Modular method has been applied in the design of the hardware; the paper focuses on layout of track ing circuit for the car and desig n ideas for the software. The experime nt result proves that the desig ned in tellige nt car is stable in operati on and good in track ing performa nee.Keywords: ARM In tellige nt Tracki ng1、IntroductionIn the 21st century, with development of scienee and tech no logy, researches on in tellige nt car and its correlative techniques have become the focus in this field. Aiming to enhance practical ability ,innovation, and teamwork performa nee of college stude nts across the coun try, theEducatio n Departme nt spon sored Natio nal Un dergraduate In tellige nt Car Con test. Based on the backgro und, the paper in troduces the desig n of multifu ncti onal in tellige nt car controller on embeddedplatform, including design of hardwarecircuit and software implementation for key functional modules.2、Design of hardwareBy fun cti on and applicati on, the con troll ing platform for the in tellige nt car is divided into several modules as show n below.2.1 Desig n of core moduleAT91SAM7S256 microprocessor produced by ATMEL has bee n adopted for the controller of the car, which a 32-bit low-power RISC microprocessor chip based on ARM7 TDMI-S core, and embedded with 64KB SARM, 256KB high-speed Flash and JTAG port for downloading or debugging of the program. As the core comp onent of the car, the microprocessor plays a key role in con troll ing all running statuses of the car. PWM gen erat ing module in side it can be cha nge duty cycle of outputted square wave by programming, and thus change the voltage loaded on the DC motor, which is amplified to con trol the revoluti on speed of the motor. The ports PA0, PA1, PA2 and PA3 of the PWMnodule respectively con trol the DC motor and the steeri ng motor to perform fun cti ons such as go forward, retreat and turn etc.2.2 Desig n of power moduleThe car is powered by four AA dry batteries. The voltage is outputted through low-Noise LDO regulator MIC5209-3.3 to supply power for ARM7 chips and peripheral circuits. The working current of MIC5209-3.3 is as high as 500mA. Wheninput voltage is above 3.5V, the module of MIC5209-3.3 can output stable voltage of 3.3V and achieve low power con sumpti on.2.3 Temperature detecti on ModuleMono-li ne digital temperature sen sor DS18B20 is used to detect temperature in the car. The measure range is from - 55C to +125C, with in creme nt of 0.5 C. It is low in power con sumpti on and small in size, occupy ing only one I/O port.2.4 Auto track ing module2.4.1 Prin ciples for track ing of i ntellige nt carTrack ing means that the car goes along the two-centimeter-wideblack guide line on the white floor.Infrared acquisition and camera shooting acquisition are com monly used for it.Infrared acquisition: Taking advantage of the feature thatin frared light can cha nge its reflective quality accord ing toobject surface of various colors. During running the car continu ously sends in frared light to the gro und, which will, either bereflected back by the white floor and received by the recei ving tube in the car, or be absorbed by the black guide line and thus missed by the receivi ng tube. By this means the black guide line is positioned to identify the path for the car.Camerashooting acquisition: In certain resolution samplethe image by in terlaced sca nning. Whensca nning a point, image sensor transfers the gray threshold into corresponding voltage which will be outputted via video sig nal port. As the car achieves auto track ing by recog nizing the black guide line on the track, the image processing is a process of extracting the dest in atio n guide line. The task of image process ing program is to identify the dots in the black-and-white image and filterno ise, record dot positi ons relative to the image, and fin ally, by algorithm of control strategy, realize tracking and turning of the car along the guide line.2.4.2 In stallati on of tracki ng in frared probeChoosing proper detection method and sensor is the importa nt factor to achieve track ing. Here we choose in frared acquisition.Correct installation of device is also a decisivefactor for accomplishme nt of track ing circuit. In terms ofsimplicity, eas in ess, practicality and reliability, four in frared probes n eed be in stalled on the front chassis of the car to fulfill two-staged directi onal correcti on con trol to enhance the reliability of tracking. Four tracking sensors have bee n fixed, all in one line, among which L1 and R1 are primary sen sors for directi on con trol; L2 and R2 are sec on dary sen sors. The distanee between the two ipsilateral sensors should nor be more tha n width of the black directi on con trol. When the car is running, the black guide line is always kept right betwee n the two primary sen sors L1 and L2. When the car goes off the black line, the primary sen sors detect it, and thus the ARM7 chip detect level jump and execute the pre-prepared correction program to n avigate the car back onto the track. The sec on dary sen sors are actually a back-up for the primary. Once the car offsets the track for in ertia, bey ond the reach of detecti on of the primary probes, the sec on dary perform to correct the motion of the car, so as to ensure the reliability of tracking.3 Desig n of softwareThe software is developed in C Ian guage in Keil Uvisi on3IDE, debugged and downloaded in J-Link ARMemulator. J-Link is a JTAGemulator which was brought out by SEGGER USAto supportemulati on chips with ARM core. It works with IDEs such asIAREWARMADS, Keil, WINARM, and RealView, supports allARM7/ARM9 core chips simulatio n, and seamlessly conn ects with various IDE by RDI in terface. Easy to operate and to connectto, it is the most practical tool for study and development of ARM.The key for the desig n of software lies in the con trolprocess of track ing. The sen sors are equipped with E3F-DS10C4in tegrated in frared probes with photoelectric switch. Thereare only three wires (power wire, ground wire, and signal wire ) at the output pin of the module. Connect the signal wire to I/O port of ARM7 chip, and execute enquiry check. Low level will be detected for the black guide line, while high level for the white floor. Accord ing to the prin ciples stated above, flows of the algorithm for con trol tracki ng of the car. Two-stagecon trol method is adopted to en sure the car' s adhere nee to the black guide line, and the effect is satisdied.4 Debugg ing of the fini shed carBased on the design scheme presented above, finish making of PCB board for hardware circuit of the car, welding of components, and debugging and downloading of the software. Test the car for several times on the track made of white KT board in the middle of which a two-ce ntimeter-wide black guide line is pasted. The results have showed that, the car runs steadily eve n at a high speed along straight blackguide line. Whe n around the curve, if con trol the speed properly, the car goes smoothly as well. Two pieces of experie nee as show n below: (1) E3F-DS10C4Dhotoelectric sensor should be fixed as close tothe ground as possible to minimize the interferenee of environmental light to it. Vertical height of the sensor had better be 5~8mm.Too far distanee from the ground causes weak reflective sig nal and unstable output of up level sig nal;too close dista nee may damage the sen sor and inten sify the effect of diffuse reflecti on.(2) Due to com mon DC motor adopted for it, the control of thecar is not accurate and stable eno ugh to perform a break tur n uni ess several same photoelectric sen sors are added to the bottom of the car.5 Con clusi onIn tellige nt car is a front subject which has syn thesizedmany other subjects and has a widely-applied prospect. It particularly helps to develop the prese nt Chin ese undergraduates ' imagination,practical abilities, teamaware ness, and hi-tech inno vati on capacity.Refere nces[1] Wu Binghua, Huang Weihua, Cheng Lei among others,Systematic Desig n of In tellige nt Car Based on RouteIden tificati on [J].

大学智能汽车英文作文
大学智能汽车英文作文英文:As a university student, I am excited about the development of intelligent cars. Intelligent cars, also known as self-driving cars, are vehicles that can drive themselves without human intervention. They use advanced technologies such as sensors, cameras, and GPS to navigate and make decisions on the road.One of the biggest advantages of intelligent cars is their potential to reduce accidents caused by human error. According to the National Highway Traffic Safety Administration, 94% of accidents in the United States are caused by human error. With intelligent cars, this number could be significantly reduced. For example, if a driver falls asleep at the wheel, the car's sensors can detect this and take over the driving.Intelligent cars also have the potential to reducetraffic congestion. With their ability to communicate with each other and with traffic management systems, they can optimize routes and speeds to reduce congestion on the roads.However, there are also concerns about the safety and security of intelligent cars. Hackers could potentially take control of the car's systems, causing accidents or even using the car as a weapon. There are also concerns about the ethical decisions that intelligent cars may have to make in certain situations, such as deciding between hitting a pedestrian or swerving into oncoming traffic.Overall, I believe that the development of intelligent cars is an exciting step forward in transportation technology. While there are certainly challenges to overcome, the potential benefits are significant.中文:作为一名大学生,我对智能汽车的发展感到兴奋。

智能车辆英文作文Smart vehicles are revolutionizing the way we travel. With advanced technology, these vehicles are equipped to make driving safer and more efficient. They can communicate with each other and with traffic signals, reducing the risk of accidents and improving traffic flow.One of the key features of smart vehicles is their ability to navigate without human input. Using GPS and sensors, they can determine the best route to take and adjust their speed and direction accordingly. This not only reduces the burden on drivers, but also minimizes the likelihood of getting lost or stuck in traffic.In addition to their navigation capabilities, smart vehicles are also designed to be more environmentally friendly. Many of them are electric or hybrid, reducing the reliance on fossil fuels and lowering emissions. This is a crucial step in combating climate change and creating a more sustainable transportation system.Another benefit of smart vehicles is their potential to reduce congestion on the roads. By communicating with each other, they can coordinate their movements to avoid bottlenecks and minimize delays. This can lead to a smoother and more efficient flow of traffic, benefiting everyone on the road.Furthermore, smart vehicles have the potential to make transportation more accessible to people with disabilities or limited mobility. With features such as autonomous driving and advanced assistive technologies, these vehicles can provide greater independence and freedom to those who may have difficulty driving traditional vehicles.Overall, smart vehicles have the potential to revolutionize the way we think about transportation. With their advanced technology and innovative features, they are paving the way for a safer, more efficient, and more inclusive future of mobility.。

中英文资料对照外文翻译Intelligent VehicleOur society is awash in “machine intelligence” of various kinds.Over the last century, we have witnessed more and more of the “drudgery” of daily living being replaced by devices such as washing machines.One remaining area of both drudgery and danger, however, is the daily act ofdriving automobiles. 1.2million people were killed in traffic crashes in 2002, which was 2.1% of all globaldeaths and the 11th ranked cause of death . If this trend continues, an estimated 8.5 million people will be dying every year in road crashes by 2020. in fact, the U.S. Department of Transportation has estimated the overall societal cost of road crashes annually in the United States at greater than $230 billion .when hundreds or thousands of vehicles are sharing the same roads at the same time, leading to the all too familiar experience of congested traffic. Traffic congestion undermines our quality of life in the same way air pollution undermines public health.Around 1990, road transportation professionals began to apply them to traffic and road management. Thus was born the intelligent transportation system (ITS). Starting in the late 1990s, ITS systems were developed and deployed。

Traffic Technology International, 2013,3(1):31-41.英文原文The Intelligent Vehicle InitiativeG StarkIn the wake of the computer and information revolutions, motor vehicles are undergoing the most dramatic changes in their capabilities and how they interact with drivers since the early years of the century.In 1908, the emergence of the Henry Ford Model T represented a major breakthrough in car design. It not only pioneered the easy replacement of parts and mass production, but also its "user-friendly" mode of operation, so that anyone can easily drive. In the past 90 years, with fewer and fewer simple cars like the Ford Model T, the car has quickly become a sophisticated “mobile computer” that plays the role of a navigator, escort, and even a second driver. These new features not only changed our driving style, but also improved the quality of transportation services and the ability to save lives, and provided support for the competitiveness of the US industry.However, the performance of smart cars is not only that. Conversely, these components that make vehicles more intelligent, such as newinformation, safety and automation technologies, arrive on the market as spare parts, or as optional equipment, or as special accessories for after-sales services. In order to improve driver safety, these technologies have been continuously developed and put on the market. However, individual technologies have not yet been integrated and they cannot create fully intelligent vehicles that are highly collaborative with drivers.The automotive industry has realized and solved the influx of potential uncoordinated technologies. But their progress is hindered by technical and economic barriers, uncertain consumer preferences, and imperfect standards and guidelines. In addition, neither traditional car manufacturers nor government regulators (unless the security issues are obvious) can control the use of aftermarket products, especially in the use o f trucks and buses. However, there is no “people-oriented” smart vehicle that attempts to integrate and coordinate various technologies to solve problems. We may not only lose the opportunity to implement new in-vehicle technology, but may even unintentionally reduce the safety and performance of driving.Recognizing the importance of intelligent vehicles and the potential dangers of human factors in vehicle design, the Ministry of Transport launched the Intelligent Vehicles Initiative (IVI) in 1997. This initiative aims to accelerate the development and integration of automotive systems to help cars, trucks and bus drivers operate more safely and effectively.The 1980s TV series “Knight Ranger” features smart vehicles that can cross over tall buildings, seem to drive the supersonic itself, spy on bad guys, and have English words and housekeepers. This car is not only smart but smart. Although smart vehicles in the real world will not be able to fly over traffic, they will have strong capabilities. As envisioned by the International Vaccine Research Institute, smart vehicles will be able to provide route instructions, feel objects, warn drivers that collisions will occur, auto signals help drivers stay alert in emergency situations, and may eventually be able to take over driving.The computer-based technology of information and motor vehicles, however, is not a new use. A wide range of automotive computers began the 1980s with the aim of improving vehicle operation and driver comfort. These technologies include the electronic control of the performance of fuel injection engines, especially the reduction of vehicle emissions, improved fuel economy, anti-lock braking systems to help drivers maintain control over slippery roads, and cruise control systems to reduce driver's driving for a long period of time. tedious. And these technologies are mainly to strengthen the vehicle, the latest wave in vehicle technology, of which the most interested is the purpose of the IVI's capabilities, and is intelligent transportation systems designed to strengthen the capabilities of the driver. These systems include early warning and information, driving assistance and automation technology.Research Plan The original research plan for the Mack IVI FOT included requirements to install the LDWS, TSA, and ACN systems on a test fleet of 36 tanker trucks operated by McKenzie Tank Lines in normal revenue service over a 19-month period. The final research plan was a revision of the original plan, because several technical problems with the data-acquisition and transmission systems delayed the start of the FOT. This in turn created logistical problems with the installation of systems and deployment of trucks in the test fleet. Consequently, the FOT was performed over a 12-month period, with a primary focus on the safety benefits of the LDWS, which was installed on 22 trucks. Since the Eaton VORAD (EVT-300) collision warning system (CWS) was standard equipment on the McKenzie Tank Lines tractors used in the FOT, this system was active throughout the FOT. The CWS was not disabled during the FOT, because driving with the CWS was considered to be valid baseline driving for McKenzie Tank Lines drivers, and it would be difficult to separate the effects of removing the CWS and adding the LDWS. All trucks were also equipped with data acquisition and communications equipment. LDWS Evaluation. Use of the LDWS was expected to affect driving performance in two ways. First, there is the immediate effect of warning the driver of a potential lane excursion, which gives the driver an opportunity to change his or her driving behavior before making a large lane excursion. Second, after gainingexperience using the LDWS, the driver’s overall driving performance may improve even without the use of the system. Another possibility is that a driver’s driving performance may decline when the system is disabled, because the driver may become dependent on the system. Three conditions were compared in the experimental design: ♦Phase I –Baseline Period: Data collected during this period would characterize the driving behavior of drivers who were not receiving LDWS feedback.♦ Phase II – Active Period: Data collected during this period would characterize the driving behavior of drivers receiving LDWS feedback.♦ Phase III – Post-Active Period: Data collected during this period would characterize the driving behavior of drivers after the LDWS feedback had been deactivated.Just as people have different professional capabilities, different types and levels of vehicle-mounted smart vehicle technology give “intelligence” to complement this driver. The driver information system expands the knowledge of the driver's route and location. Early warning systems, such as collision avoidance techniques, improve the driver's perception of what is happening in the surrounding environment. Automate and drive technical assistance and simulate the driver's thoughts and actions to actual operations or in case of emergency, long-term vehicles are temporary. However, in smart vehicles will expand the driver's ability, it may also increase the driver's traditional role. Inparticular, within the technology of the new car, the role of the person is expanded from sensory motor skills, writes Thomas Sheridan, professor who is responsible for the Human Machine Systems Laboratory at the Massachusetts Institute of Technology (MIT), "this plan, Programmers, ITS studies in automation, diagnosticians, monitoring learners and managers show the feasibility of the benefits of many technologies that will be applied in smart vehicles.The route guidance system will help drivers to better drive in unfamiliar streets or Finding the fastest route to their destination In 1992 and 1993, field trials conducted by the Department of Transportation at Orlando TravTek showed that a tourist-guided vehicle equipped with a route guidance system reduced the problem of 30% of vehicles turning the wrong corner. Compared with tourists with paper maps, it saves 20% of the time.The collision avoidance system can strengthen traffic safety regulations and completely prevent traffic accidents. According to studies, if drivers can respond for more than half a second, they can avoid 60% of the time. Road traffic accidents and 30% of head-on collisions, and 75% of vehicle accidents are caused by driver's devastation.The National Highway Traffic Safety Administration (NHTSA) estimates that each year The country’s use of these three types of collision avoidance system can avoid 1.1 million traffic accidents and account for 17% of the total number of traffic accidents, which can save 17,500 lives (belt and airbags save about10,500 people) and restore 26 billion US dollars. The other safety facilities are under test, including the automatic collision notification system. When the airbag of a car pops up, the system will automatically send a distress signal, and the drowsy driver warning system can prevent the driver from getting drowsy while the car is driving. To sleep.The in-vehicle automation system can take over driving in case of an emergency or autopilot if it allows long periods of driving. In 1996, the National Highway Traffic Safety Administration began field testing an intelligent cruise control system that can automatically adjust the vehicle's speed to maintain a safe distance from the vehicle in front of it to assess the safety impact of this technology. The more dramatic scene appeared in the drive called "Let's open your hands and let your feet go." Last summer, the National Association of Autonomous Highway Systems (NAHSC), jointly organized by the Ministry of Transport and nine other public and private organizations, demonstrated a prototype of a future fully-automated vehicle on a 12-km section of the I-15 road in Santiago. In the future, the automatic road management system will increase the supervision of traffic managers by 2-3 times at higher speeds and shorter distances. The system may also eliminate the occurrence of human-induced traffic accidents and improve road safety.In addition to providing passengers with safe and efficient transportation, the federal government expects that the inherentdevelopment trend of smart cars may also increase the economic competitiveness of the United States.In order for smart cars to reach their maximum potential, they must be able to communicate with intelligent transportation infrastructure systems and other smart cars. For example, communicating with intelligent infrastructure systems can enable smart cars to understand the occurrence of accidents and then actively choose routes in real time. . The smart car can also act as a probe and send information about the road conditions to the intelligent infrastructure system to create richer road conditions basic information. In addition, fully automated vehicles should also be able to rely, to some extent, on the guidance provided by intelligent infrastructure systems and other smart cars. For example, not long ago, the American Helicopter Association (AHS) in San Diego showed that an automatic car equipped with a magnetic sensor under a bumper was successfully guided by a 1.2 m magnet implanted under the surface of the road.In the next 5 to 10 years, we should be able to see the first generation of products with special drive information and alarm system capabilities. With the development of information these systems will be increasingly perfect. Although the anti-collision system will provide some automatic assistance, drivers still have full control of the car. In addition, because of the initial communication capabilities with the intelligentinfrastructure system, the car will be more intelligent in terms of real-time detection of road conditions.In about 10 to 15 years, the application of some improvement measures will bring us better and smarter second-generation products. Although the driver still has full control of the car, the collision avoidance system will be able to take temporary control in emergency situations. In addition, more sophisticated voice recognition systems will be incorporated into the driver's interaction with the car. Vehicles can communicate with each other to improve their anti-collision ability. Of course, communication with intelligent infrastructure systems will also be more active and effective.In about 20 years, in the third generation of products, we will be able to see fully automated road systems, integrated systems for vehicles and infrastructure, and closer interaction between drivers and cars, such as the use of visual enhancements and visual displays.Looking back at a century of flooding technology, cars stand out as a particularly dynamic invention. In the next century, this vitality will promote the development of information and computer technology. Our next challenge is to integrate new information, security and automation technologies to create people-oriented smart vehicles that improve safety, ground drive efficiency and economic competitiveness.中文译文智能车辆研究G Stark本世纪初期,在计算机和信息革命的影响下,汽车经历了性能和与驾驶者之间的互动方面最富戏剧性的变革。

关于智能汽车总结英文作文
关于智能汽车总结英文作文英文:Smart cars, also known as intelligent vehicles, have been a hot topic in recent years. As a virtual assistant, I have been asked many questions about this topic. In my opinion, smart cars are a revolutionary development in the automobile industry.Firstly, smart cars are equipped with advanced sensors and cameras that can detect and analyze the surrounding environment. This allows the car to make decisions and take actions based on real-time information. For example, if a pedestrian suddenly appears in front of the car, the smart car can automatically apply the brakes to avoid a collision.Secondly, smart cars are connected to the internet and can communicate with other vehicles and infrastructure.This enables them to share information about traffic conditions, road hazards, and weather conditions. As aresult, smart cars can optimize their routes and avoid congestion, saving time and reducing fuel consumption.Thirdly, smart cars are equipped with advanced driver assistance systems (ADAS) that can assist drivers invarious ways. For example, lane departure warning systems can alert drivers when they are drifting out of their lane, while adaptive cruise control can maintain a safe distance from the vehicle in front.In conclusion, smart cars represent a majorbreakthrough in the automobile industry, and their benefits are numerous. They can improve safety, reduce congestion, save time, and enhance the driving experience.中文:智能汽车,也被称为智能化车辆,近年来成为了热门话题。

智能车辆研究外文文献翻译(含:英文原文及中文译文)文献出处:G Stark. The Intelligent Vehicle Initiative[J]. Traffic Technology International, 2013,3(1):31-41.英文原文The Intelligent Vehicle InitiativeG StarkIn the wake of the computer and information revolutions, motor vehicles are undergoing the most dramatic changes in their capabilities and how they interact with drivers since the early years of the century.In 1908, the emergence of the Henry Ford Model T represented a major breakthrough in car design. It not only pioneered the easy replacement of parts and mass production, but also its "user-friendly" mode of operation, so that anyone can easily drive. In the past 90 years, with fewer and fewer simple cars like the Ford Model T, the car has quickly become a sophisticated “mobile computer” that plays the role of a navigator, escort, and even a second driver. These new features not only changed our driving style, but also improved the quality of transportation services and the ability to save lives, and provided support for the competitiveness of the US industry.However, the performance of smart cars is not only that. Conversely, these components that make vehicles more intelligent, such as newinformation, safety and automation technologies, arrive on the market as spare parts, or as optional equipment, or as special accessories for after-sales services. In order to improve driver safety, these technologies have been continuously developed and put on the market. However, individual technologies have not yet been integrated and they cannot create fully intelligent vehicles that are highly collaborative with drivers.The automotive industry has realized and solved the influx of potential uncoordinated technologies. But their progress is hindered by technical and economic barriers, uncertain consumer preferences, and imperfect standards and guidelines. In addition, neither traditional car manufacturers nor government regulators (unless the security issues are obvious) can control the use of aftermarket products, especially in the use o f trucks and buses. However, there is no “people-oriented” smart vehicle that attempts to integrate and coordinate various technologies to solve problems. We may not only lose the opportunity to implement new in-vehicle technology, but may even unintentionally reduce the safety and performance of driving.Recognizing the importance of intelligent vehicles and the potential dangers of human factors in vehicle design, the Ministry of Transport launched the Intelligent Vehicles Initiative (IVI) in 1997. This initiative aims to accelerate the development and integration of automotive systems to help cars, trucks and bus drivers operate more safely and effectively.The 1980s TV series “Knight Ranger” features smart vehicles that can cross over tall buildings, seem to drive the supersonic itself, spy on bad guys, and have English words and housekeepers. This car is not only smart but smart. Although smart vehicles in the real world will not be able to fly over traffic, they will have strong capabilities. As envisioned by the International Vaccine Research Institute, smart vehicles will be able to provide route instructions, feel objects, warn drivers that collisions will occur, auto signals help drivers stay alert in emergency situations, and may eventually be able to take over driving.The computer-based technology of information and motor vehicles, however, is not a new use. A wide range of automotive computers began the 1980s with the aim of improving vehicle operation and driver comfort. These technologies include the electronic control of the performance of fuel injection engines, especially the reduction of vehicle emissions, improved fuel economy, anti-lock braking systems to help drivers maintain control over slippery roads, and cruise control systems to reduce driver's driving for a long period of time. tedious. And these technologies are mainly to strengthen the vehicle, the latest wave in vehicle technology, of which the most interested is the purpose of the IVI's capabilities, and is intelligent transportation systems designed to strengthen the capabilities of the driver. These systems include early warning and information, driving assistance and automation technology.Research Plan The original research plan for the Mack IVI FOT included requirements to install the LDWS, TSA, and ACN systems on a test fleet of 36 tanker trucks operated by McKenzie Tank Lines in normal revenue service over a 19-month period. The final research plan was a revision of the original plan, because several technical problems with the data-acquisition and transmission systems delayed the start of the FOT. This in turn created logistical problems with the installation of systems and deployment of trucks in the test fleet. Consequently, the FOT was performed over a 12-month period, with a primary focus on the safety benefits of the LDWS, which was installed on 22 trucks. Since the Eaton VORAD (EVT-300) collision warning system (CWS) was standard equipment on the McKenzie Tank Lines tractors used in the FOT, this system was active throughout the FOT. The CWS was not disabled during the FOT, because driving with the CWS was considered to be valid baseline driving for McKenzie Tank Lines drivers, and it would be difficult to separate the effects of removing the CWS and adding the LDWS. All trucks were also equipped with data acquisition and communications equipment. LDWS Evaluation. Use of the LDWS was expected to affect driving performance in two ways. First, there is the immediate effect of warning the driver of a potential lane excursion, which gives the driver an opportunity to change his or her driving behavior before making a large lane excursion. Second, after gainingexperience using the LDWS, the driver’s overall driving performance may improve even without the use of the system. Another possibility is that a driver’s driving performance may decline when the system is disabled, because the driver may become dependent on the system. Three conditions were compared in the experimental design: ♦Phase I –Baseline Period: Data collected during this period would characterize the driving behavior of drivers who were not receiving LDWS feedback.♦ Phase II – Active Period: Data collected during this period would characterize the driving behavior of drivers receiving LDWS feedback.♦ Phase III – Post-Active Period: Data collected during this period would characterize the driving behavior of drivers after the LDWS feedback had been deactivated.Just as people have different professional capabilities, different types and levels of vehicle-mounted smart vehicle technology give “intelligence” to complement this driver. The driver information system expands the knowledge of the driver's route and location. Early warning systems, such as collision avoidance techniques, improve the driver's perception of what is happening in the surrounding environment. Automate and drive technical assistance and simulate the driver's thoughts and actions to actual operations or in case of emergency, long-term vehicles are temporary. However, in smart vehicles will expand the driver's ability, it may also increase the driver's traditional role. Inparticular, within the technology of the new car, the role of the person is expanded from sensory motor skills, writes Thomas Sheridan, professor who is responsible for the Human Machine Systems Laboratory at the Massachusetts Institute of Technology (MIT), "this plan, Programmers, ITS studies in automation, diagnosticians, monitoring learners and managers show the feasibility of the benefits of many technologies that will be applied in smart vehicles.The route guidance system will help drivers to better drive in unfamiliar streets or Finding the fastest route to their destination In 1992 and 1993, field trials conducted by the Department of Transportation at Orlando TravTek showed that a tourist-guided vehicle equipped with a route guidance system reduced the problem of 30% of vehicles turning the wrong corner. Compared with tourists with paper maps, it saves 20% of the time.The collision avoidance system can strengthen traffic safety regulations and completely prevent traffic accidents. According to studies, if drivers can respond for more than half a second, they can avoid 60% of the time. Road traffic accidents and 30% of head-on collisions, and 75% of vehicle accidents are caused by driver's devastation.The National Highway Traffic Safety Administration (NHTSA) estimates that each year The country’s use of these three types of collision avoidance system can avoid 1.1 million traffic accidents and account for 17% of the total number of traffic accidents, which can save 17,500 lives (belt and airbags save about10,500 people) and restore 26 billion US dollars. The other safety facilities are under test, including the automatic collision notification system. When the airbag of a car pops up, the system will automatically send a distress signal, and the drowsy driver warning system can prevent the driver from getting drowsy while the car is driving. To sleep.The in-vehicle automation system can take over driving in case of an emergency or autopilot if it allows long periods of driving. In 1996, the National Highway Traffic Safety Administration began field testing an intelligent cruise control system that can automatically adjust the vehicle's speed to maintain a safe distance from the vehicle in front of it to assess the safety impact of this technology. The more dramatic scene appeared in the drive called "Let's open your hands and let your feet go." Last summer, the National Association of Autonomous Highway Systems (NAHSC), jointly organized by the Ministry of Transport and nine other public and private organizations, demonstrated a prototype of a future fully-automated vehicle on a 12-km section of the I-15 road in Santiago. In the future, the automatic road management system will increase the supervision of traffic managers by 2-3 times at higher speeds and shorter distances. The system may also eliminate the occurrence of human-induced traffic accidents and improve road safety.In addition to providing passengers with safe and efficient transportation, the federal government expects that the inherentdevelopment trend of smart cars may also increase the economic competitiveness of the United States.In order for smart cars to reach their maximum potential, they must be able to communicate with intelligent transportation infrastructure systems and other smart cars. For example, communicating with intelligent infrastructure systems can enable smart cars to understand the occurrence of accidents and then actively choose routes in real time. . The smart car can also act as a probe and send information about the road conditions to the intelligent infrastructure system to create richer road conditions basic information. In addition, fully automated vehicles should also be able to rely, to some extent, on the guidance provided by intelligent infrastructure systems and other smart cars.

I. INTRODUCTION Many researchers have worked on vehicle motion planning. The form of the vehicle includes car-like, differential drive, omni-directional, and other models. Balkcom [3] developed the time optimal trajectories for the bounded velocity model of differential drive robots. Jung [4] and Moore [5] dealt with omnidirectional vehicles; the control strategy employed by these papers consists of building a geometric path and tracking the path by using feedback control. Huang [6] proposed an approach to vision-guided local navigation for nonholonomic robot based upon a model of human navigation. The approach uses the relative headings to the goal and to obstacles, the distance to the goal, and the angular width of obstacles, to compute a potential field. The potential field controls the angular acceleration of the robot, steering it toward the goal and away from obstacles. Hamner [7] maneuvered an outdoor mobile robot that learns to avoid collisions by observing a human driver operate a vehicle equipped with sensors that continuously produce a map of the local environment. The paper describes implementation of steering control that models human behavior in trying to avoid obstacles while trying to follow a desired path. Hwang [8] developed the trajectory tracking and obstacle avoidance of a car-like mobile robot within an intelligent space via mixed H2 /H∞ decentralized control. Two CCD cameras are used to realize the position of the robot and the position of the obstacle. A reference command for the proposed controller of the robot is planned based on the information from these cameras.

单片机智能小车中英文对照外文翻译文献(文档含英文原文和中文翻译)基于单片机的智能小车单片机之所以被称为微控制器,是因为它最早被用在工业控制领域。
单片机是由芯片内仅有CPU的专用处理器发展而来。
最早的设计理念是通过将大量外围设备和CPU集成在一个芯片内,INTEL的Z80是最早按照这种思想设计出的处理器,从此以后,单片机和专用处理器的发展便分道扬镳。
早期的单片机都是8位或4位的。
其中最成功的是INTEL的8031,因为简单可靠而且性能不错获得了广泛的好评。
此后在8031基础上研制出了MCS51系列单片机系统。
基于这一系统的单片机系统直到现在还在广泛使用。
随着工业控制领域要求的提高,开始出现了16位单使计算机系统更小,更容易集成进复杂的但是对其要求严格的控制设备当中。
片机,但因为性价比不理想并未得到很广泛的应用。
90年代后随着消费电子产品大发展,单片机技术得到了巨大的普遍的认可。
随着INTEL i960系列特别是后来的ARM系列的广泛应用,32位单片机迅速取代16位单片机的高端地位,并且进入主流市场。
而传统的8位单片机的性能也得到了飞速提高,处理能力比起80年代提高了数百倍。
目前,高端的32位单片机主频已经超过300MHz,性能直追90年代中期的专用处理器,而普通的型号出厂价格跌落至1美元,最高端的型号也只有10美元。
当代单片机系统已经不再只在裸机环境下开发和使用,大量专用的嵌入式操作系统被广泛应用在全系列的单片机上。
而在作为掌上电脑和手机核心处理的高端单片机甚至可以直接使用专用的Windows和Linux操作系统。
单片机与专用处理器相比适合应用于嵌入式系统,因此它得到了最多的应用。
事实上单片机是世界上数量最多的计算机。
现代人类生活中所用的几乎每件电子和机械产品中都会集成有单片机。
手机、电话、计算器、家用电器、电子玩具、掌上电脑以及鼠标等电脑配件中都配有1-2部单片机。
而个人电脑中也会有为数不少的单片机在工作。

One of the most exciting developments in recent years is the emergence of smart or intelligent cars. These vehicles are equipped with advanced technology such as sensors, cameras, andartificial intelligence to enhance the driving experience and improve safety on the road.One of the key features of smart cars is their ability to communicate with other vehicles and with the infrastructure around them. This can help to prevent accidents and reduce traffic congestion. For example, smart cars can receive real-time traffic information and adjust their routes to avoid congested areas. They can also communicate with each other to coordinate lane changes and merges, making driving safer and more efficient.In addition to improving safety, smart cars also offer a range of convenience features. For instance, some smart cars are equipped with voice recognition technology, allowing drivers to control various functions of the vehicle with simple voice commands. This can be especially useful for tasks like adjusting the climate control, selecting music, or making hands-free phone calls while driving.Furthermore, smart cars can also be connected to the internet, allowing drivers and passengers to access a wide range of services and information while on the go. For example, they can provide real-time weather updates, navigation assistance, and even access to entertainment content. This connectivity can make long drives more enjoyable and help drivers stay informed and connected even when they're on the road.In terms of environmental impact, smart cars also have the potential to reduce emissions and improve fuel efficiency. By optimizing driving patterns and reducing idling time, smart cars can help to minimize their carbonfootprint and contribute to a more sustainable transportation system.Overall, the development of smart cars represents a significant leap forward in automotive technology.
