汽车安全性分析毕业设计

摘要

随着汽车工业的迅速发展，汽车保有量的逐渐增多，交通事故也节节攀升，汽车的安全性逐渐成为人们关注的首要话题，人们对汽车安全性的需求也不断增高，因此也涌现了很多汽车安全新技术、新装置。

本论文介绍了汽车安全性（制动系统、悬架系统、车身稳定系统）和被动安全系统。

汽车制动系统中介绍了ABS（防抱死制动系统）、EBD（电子制动动力分配系统），并对二者的控制进行比较，在汽车ASR（加速防滑控制系统）中讲述其原理、组成、功用、控制。

汽车悬架系统分别介绍了被动悬架、主动悬架、半主动悬架的优缺点，以及应用现状及发展趋势，并把它们进行对比。

车身稳定系统中介绍了ESP(电子稳定程序控制系统)系统结构组成、工作原理、ESP 系统的应用并与ABS进行了对比。还对ESP系统进行了全面的适用性和可靠性检测试验，并且说明了ESP系统的性能。

被动安全性中介绍了安全带分类，及汽车安全带作用过程，安全气囊及安全气囊开发上存在的两种思想，另外介绍了能量吸收式转向柱、护膝板、座椅头枕等被动安全装置。

安全新技术介绍了福特汽车公司的一些概念车采用的安全新技术，介绍说明了EyeCar技术，CamCar技术，SensorCar技术，外部安全气囊技术和SecurCar技术。

在科技高速发展的今天轿车主动安全技术和被动安全技术虽然都有很大的发展，但是它们各自为阵，两者并没有整合起来。所以将主动安全技术和被动安全技术进行有效的整合将是未来轿车安全技术的新研究方向。

Abstract

Along with the automobile industry rapid development, automobile population increases gradually, the transportation accident rate also successively climbs, the automobile security becomes the most important topic gradually which the people pays attention to, the people also unceasingly advance to the automobile secure demand, therefore also has emerged the very many automobiles peaceful brand-new technology, the new installment. The paper reviews the automobile initiative security (Brake System, Suspension System, Vehicle Stability Control System) and passive security

In the automobile braking system introduced ABS (Anti-lock Brake System), EBD (Electronic Braking Distribution), and the control has carried on the comparison to the two, actuates ASR (Acceleration Skid Control System) narrates its principle, the composition, the function, the control.

The automobile suspension fork system introduced separately the passive suspension fork, the active suspension fork, the semi-active suspension fork good and bad pionts application present situation and the development tendency, and have carried on them the contrast.

In the automobile body stable system introduced the ESP (Electronic Stabilization Program Control System) system structure composition, the principle of work, the ESP system application and has carried on the contrast with ABS and ASR. Also has carried on comprehensive serviceable and the reliable examination experiment to the ESP system, and explained the ESP system performance.

In the passive security introduced the safety belt classification, and the automobile safety belt function process, the security aerocyst and has two kind of though in the security aerocyst development development, moreover introduced the energy absorption type steering column, protects the knee swell, the chair head rest and so on the passive safety device.

The peaceful brand-new technology introduced the Ford Motor Company’s some concept EyeCar technology, the CamCar technology, the SensorCar technology, the outside security technology and the SecurCar technology.
