GTR(全球统一汽车技术法规)介绍

GTR技术法规介绍全国汽车标准化技术委员会1.GTR技术法规的制定组织和《1998年协定书》GTR法规全称为全球统一汽车技术法规,由联合国世界车辆法规协调论坛(UN/WP29)负责制定发布,WP29原为联合国欧洲经济委员会内陆运输委员会下属的车辆结构工作组,在《1958年协定书》的框架下制定并实施ECE汽车技术法规,从20世纪80年代初开始,随着经济全球化的到来,许多国家和地区的政府开始认识到各自为政的汽车技术法规体系阻碍了汽车产品在全球范围内的自由流通,限制并阻碍了商品经济规律应起的作用,于是由国际上一些汽车工业发达国家牵头,开始进行国际汽车技术法规的协调与统一的工作,以打破世界各国、各地区已形成的汽车技术法规这一贸易技术壁垒。

在当时情况下,联合国欧洲经济委员会车辆结构工作组(UN/ECE/WP29)成了开展这种世界范围内汽车技术法规协调和统一工作的主要组织。

[1]WP29于1998年6月25日制订《全球汽车技术法规协定书》,因此该协定书也就简称为《1998年协定书》。

世界各国以此协定书为法律框架,共同制修订全球统一的汽车技术法规。

该协定书在法律地位上明确原UN/ECE/WP29(联合国欧洲经济委员会车辆结构工作组)作为开展全球汽车技术法规协调和统一工作的国际组织,UN/ECE/WP29的名称随之更改为:“世界车辆法规协调论坛”(World Forum for Harmonization of Vehicle Regulations),仍简称为WP29,开始按照《全球汽车技术法规协定书》中规定的程序规则制定全球统一的汽车技术法规,到目前,《1998年协定书》的正式缔约方共计31个[2]。

历史之所以选择UN/ECE/WP29来开展全球范围内的汽车技术法规协调统一工作,其原因为:①UN/ECE/WP29成功运作《1958年协定书》,具有开展国际汽车技术法规统一工作的技术基础;②UN/ECE/WP29的广泛参与性,使其具有开展国际汽车技术法规统一工作的技术基础。

Statement of Technical Rationale and JustificationI. IntroductionCurrent regulations were designed to test for door openings in vehicles that were built in the 1960s. Aside from changes made to United States of America and Canadian requirements in the early to mid-1990s to address rear door openings, no significant changes have been made to any of the current regulations. While existing regulations governing door openings have proven largely effective, door openings continue to present a risk of serious injury or death to vehicle occupants, particularly when an occupant is unbelted.The precise size of the safety problem posed by inadvertent door openings is difficult to quantify because very few jurisdictions gather the type of crash data needed to evaluate the problem. This task is further compounded by the effect of occupant belt use on injury risk. Notwithstanding the difficulty in quantifying the overall benefit associated with the establishment of a global technical regulation internationally, the types of changes to door retention components needed to upgrade existing regulations and standards appear to be quite small. Additionally, vehicle manufacturers and the ultimate consumers of motor vehicles can expect to achieve further cost savings through the formal harmonization of differing sets of regulations and standards that already largely replicate each other.Research conducted by the United States of America indicates that there are approximately 42,000 door openings in crashes in the United States of America per year. 1/ While this number corresponds to less than one per cent of the roughly six million crashes that occur in that country each year, the majority of those crashes do not occur at speeds where a door opening is likely. Rather, door failures appear to be most common in moderate- to high-speed crashes. 2/ Structural failures of the latch and striker are the leading cause of door openings. The United States of America’s evaluation of its data indicates that about two-thirds (64.5 per cent) of door openings involve damage to the latch or striker, either alone or in combination with damage to one or more hinges. The next most likely causes of a door opening are the failure of the vehicle structure holding the door in place or the door itself. In 8.37 per cent of the evaluated cases, the door support, e.g., B-pillar or C-pillar, was damaged; while in 9.68 per cent of the evaluated cases, the door structure caused the door to open without damaging the actual door retention components. Only rarely did a door open with no damage to the door whatsoever (2.15 per cent). 1/ At the request of the Working Party on Passive Safety, the United States of America provided data on the magnitude of the door ejections and door openings based on 1994-99 National Automotive Sampling System (NASS) and Fatal Analysis Reporting System (FARS) annual estimates. No data from other jurisdictions were presented.2/ In the United States of America the average change of velocity (delta V) for crashes where a door opens is approximately 30.5 km/h; the average delta V for crashes where there is no failure of the door retention system is approximately 21 km/h.ECE/TRANS/180/Add.15pageThe type of crash also has an impact on the likely type of door failure. The primary source offailure in side impact crashes was damage to the latch/striker assembly, while damage to the doorsupports was a distant secondary source. In rollover crashes, non-structural failures, i.e., thosewhere there is no damage to the door, are more common.In 1991, the United States of America conducted an engineering analysis of door latch systems incases involving vehicle side door openings to determine the loading conditions and failure modesof door latch systems in crashes. 3/ This analysis revealed the following four distinct failuremodes:Structural FailuresStructural failures are characterized as physical damage to the latch, striker, or hinges. Othertypes of structural failures include broken attachment hardware or separation of a latch, striker, orhinge from its support structure.Detent Lever-Fork Bolt Misalignment (Bypass) FailuresDetent lever-fork bolt misalignment (bypass) failures may occur when the striker is subjected tolongitudinal forces in conjunction with lateral forces. These forces cause the fork bolt to moveand become misaligned with the detent lever, causing the latch to open. These forces mosttypically occur in frontal and oblique frontal impacts.Linkage Actuation FailuresLinkage actuation failures are caused by forces being transmitted to the door’s linkage system(i.e., the connection between the door handle and the door latch) due to vehicle deformationduring a crash. It may be possible to observe some bowing of the door after a linkage actuationfailure.Inertial Force FailuresInertial force failures are latch openings due to acceleration of latch system components relative toeach other, which produce sufficient inertial force to activate the latch. Often, there is no visibledamage to the latch or striker system. Inertial loading typically occurs in rollover crashes or whena portion of the vehicle other than the door is impacted at a high speed.These four failure modes can be categorized as either structural failures or actuation failures.Structural failures usually leave clear evidence of the component failure and result in aninoperable door retention system. Actuation failures consist of latch by-pass, linkage actuation,and inertial force failures. Often a door opening caused by an actuation failure will not leave anyreadily visible evidence that the crash caused the door to open and will not affect the retentionsystem’s subsequent ability to open and close correctly. Thus, many of the failures associatedwith a latch by-pass, linkage actuation, or inertial force failure will be represented by the 2.15 percent of crashes where no damage to the door was observed.3/ Door Latch Integrity Study: Engineering Analysis and NASS Case Review,December, 1991, Docket No. NHTSA-1998-3705.ECE/TRANS/180/Add.1page 6According to the United States of America statistics, less than one per cent of occupants who sustain serious and fatal injuries in tow-away crashes are ejected through doors. Yet, despite the relatively rare occurrence of door ejections in crashes, the risk of serious or fatal injury is high when ejection does occur. Door ejections are the second leading source of ejections in all crashes in the United States of America. They are particularly likely in rollover crashes. Door ejections constitute 19 per cent (1,668) of all ejection fatalities and 22 per cent (1,976) of all ejection serious injuries in the United States of America each year. Of the approximately 42,000 door openings in the United States of America each year, side door openings constitute approximately 90 per cent (1,501) of all door ejection fatalities and 93 per cent (1,838) of the serious injuries.The rate of ejections through doors is heavily dependent on belt use. 94 per cent of serious injuries and fatalities attributable to ejections through doors in the United States of America involve unbelted occupants. While the risk of ejection will likely vary from jurisdiction to jurisdiction, based on differing rates of belt use, the incidence of door openings should be relatively constant among various jurisdictions given the similarity in door designs and the lack of occupant behaviour patterns as a factor in door failures.BackgroundII. ProceduralDuring the one-hundred-and-twenty-sixth session of WP.29 of March 2002, the Executive Committee (AC.3) of the 1998 Global Agreement (1998 Agreement) adopted a Programme of Work, which includes the development of a global technical regulation (gtr) to address inadvertent door opening in crashes. The Executive Committee also charged the Working Party on Passive Safety (GRSP) to form an informal working group to discuss and evaluate relevant issues concerning requirements for door locks and door retention components to make recommendations regarding a potential gtr.The informal working group was established in September 2002. The United States of America volunteered to lead the group’s efforts and develop a document detailing the recommended requirements for the gtr. The United States of America presented a formal proposal to the Executive Committee of the 1998 Agreement, which was adopted in June 2003 (TRANS/WP.29/2003/49). The GRSP developed the door locks and door retention gtr. At its May 2004 session, the GRSP concluded its work and agreed to recommend the establishment of this gtr to the Executive Committee.III. Existing Regulations, Directives, and International Voluntary StandardsThere are several existing regulations, directives, and standards that pertain to door locks and door retention components. All share similarities. The Canadian and US regulations are very similar to each other and the Japanese and UNECE regulations are very similar to each other. The European Union Directive is an exact alternative of the UNECE regulation requirements. The Australian regulation has commonalities to both of the above-mentioned pairs. A preliminary analysis has been made to identify the differences in the application, requirements, and test procedures of the North American and UNECE Regulations (TRANS/WP.29/GRSP/2001/1 and TRANS/WP.29/2003/49). There are no apparent conflicts between the gtr and other existing international regulations or standards. However, the gtr does incorporate aspects of the existing regulations, directives and standards that are not common to all existing requirements. Given theECE/TRANS/180/Add.17pagegenerally minor variability in the door retention designs among these jurisdictions that currentlyregulate door design, it is not expected that the additional requirements imposed by the gtr arelikely to drive major, costly changes to existing door retention designs.IV. Discussion of Issues Addressed by the gtrThe proposed gtr provides that certain door retention components on any door leading directlyinto an occupant compartment, i.e., a compartment containing one or more seatingaccommodations, must comply with the requirements of the gtr. Tractor trailers are excludedbecause they do not meet this criterion. Likewise, doors leading into cargo compartments that areseparated by a barrier would not be regulated since an individual could not access the occupantcompartment through those doors. The gtr excludes folding doors, roll-up doors, detachabledoors, and doors that provide emergency egress, as these types of doors would require entirelynew test procedures and are not in such common use as to justify the development of newrequirements and test procedures. Thus, for certain vehicle designs, some, but not all doors wouldbe regulated by the gtr.During the development of the gtr, all issues were thoroughly discussed. The followingdiscussions reflect the evaluation of the issues that lead to the final recommendations.(a) ApplicabilityThe application of the requirements of this gtr refers, to the extent possible, to the revised vehicleclassification and definitions that the Working Party on General Safety (GRSG) Common TaskInformal Group has prepared. Difficulties were encountered in determining which vehicles wouldbe covered. Currently, UNECE Regulations only apply to M1 vehicles (passenger vehicles withup to 9 seats in total) and N1 vehicles (goods vehicles weighing up to 3,500 kg gross vehiclemass). It was posited that it would be difficult to apply full door tests, such as the proposedinertial load, to large trucks and specialized vehicles. With the decision not to propose theinclusion of two full door tests, discussed in greater detail below, these concerns were largelyresolved. Likewise, the retention of a calculation for meeting the inertial load requirements wouldallow a jurisdiction to avoid applying a full-door inertial load test for doors on heavier vehicles.To address concerns about the applicability of door retention requirements to heavier vehicles, itwas proposed that the gtr only apply to passenger cars, light commercial vehicles, and vans andthat other vehicles be excluded initially, then added in the future after further evaluation ofvarious door designs. The argument in favour of a more inclusive gtr focuses attention on thecurrent United States of America, Canadian, Japanese, and Australian requirements that alreadyapply to all vehicles other than buses (M2 and M3 vehicles) and that the applicability of existingrequirements to commercial trucks has not proven problematic for vehicle manufacturers. Thisargument supports the exclusion of specific door types rather than entire classes of vehicles.ECE/TRANS/180/Add.1page 8Heavy trucks in the United States of America have been subject to that country’s door retention requirements since 1972. The United States of America requirement was extended to trucks because researchers from a major United States of America university determined in a study published in 1969 that the rate of door ejection from truck doors was approximately twice that from doors on passenger cars that met the door retention requirements. The authors of the study concluded that at 40.3 per cent, the level of door failure in the truck fleet was approximately four times the failure rate of regulated passenger cars and roughly equivalent to the rate of failure in passenger cars manufactured before 1956. They also concluded that insufficient door retention was a problem across vehicle weight classifications, with pick-up trucks, medium-weight trucks and tractor trailers all exhibiting a door failure rate in excess of 33 per cent.To accommodate both positions, the gtr will apply to all vehicles except buses, with exceptions for specific door designs. The gtr incorporates the definitions of Category 1-1 vehicles and Category 2 vehicles developed in draft Special Resolution 1 (S.R. 1) concerning common definitions and procedures to be used in global technical regulations, which will be submitted as an informal document at the one-hundred-and-thirty-fourth WP.29 session and with an expected adoption at the one-hundred-and-thirty-fifth WP.29 session. If a jurisdiction determines that its domestic regulatory scheme is such that full applicability is inappropriate, it may limit domestic regulation to vehicles with a gross vehicle weight of 3,500 kg or less. The jurisdiction could also decide to phase-in the door retention requirements for heavier vehicles, delay implementation for a few years, or even to impose only some of the gtr requirements to these heavier vehicles. For example, it is unlikely that a jurisdiction would want to require heavier truck doors to meet the dynamic inertial test rather than the calculation. On the other hand, the longitudinal and transverse load requirements have been applicable to heavy trucks in the United States of America and Canada for over thirty years without imposing any hardship on vehicle manufacturers.(b) DefinitionsDefinitions, used in this gtr, are defined in section B, paragraph 3. of this regulation, with the exception of those related to the applicability. Definitions that relate to the applicability are drawn from a draft version of S.R. 1 and are listed in Annex 5.(c) General RequirementsGRSP agreed to recommend that the gtr should specify requirements for side and back doors, door retention components and door locks. The United States of America, Canadian, and Australian regulations have provisions for back doors and door locks, the UNECE Regulations do not. Currently, UNECE Regulations require that the sliding door systems be tested in a fully latched position and an intermediate latched position. If there is no intermediate position, when unlatched, the door must move into an apparent open position. The United States of America and Canadian regulations have no latching system requirements for the sliding doors. The Working Party decided that it was appropriate to regulate the sliding side door latching system, but recognized that the existing UNECE requirement to determine whether a sliding side door was unlatched was too subjective. Accordingly, the gtr specifies a door closure warning system that activates when the sliding side door is not latched and there is no intermediate/secondary latching position.ECE/TRANS/180/Add.19pageThe inclusion of a requirement in the gtr that side doors remain shut during vehicle dynamic crashtests, as well as a requirement that at least one door per row be operable following a crash test,was considered. Existing UNECE Regulations with dynamic crash test components alreadyrequire all doors to stay closed during the test and at least one door per seat row to be operableafterwards. It is believed that it is unnecessary to repeat this requirement in the gtr and itsinclusion would make the certification process under this regulation very difficult. However,recognizing the value of such a requirement, non-UNECE countries have agreed to considerincluding a similar requirement in their domestic regulations. This will result in a harmonizedrequirement outside of the context of the gtr.Force levels identified in the current component static tests for latches and hinges have beenharmonized to eliminate variations due to rounding of unit conversions.(d) Performance Requirements(i) Hinged Doors IssuesCurrently, UNECE Regulation No. 11 has similar hinged door requirements to the NorthAmerican regulations, although UNECE Regulation No. 11 does not distinguish between cargoand non-cargo door latches. The Working Party agreed to recommend that cargo doors (i.e.,double doors) meet the same requirements as hinged doors if they provide access to the occupantseating compartment. Additionally, the term "cargo door" has been eliminated to clarify thatdoors that do not lead into an occupant compartment with one or more seat positions are notregulated by the gtr.(ii) Load TestsBoth regulations require load tests of the hinge systems in the longitudinal and transversedirections. These tests remain, but have been reworded such that the loads are applied based onthe alignment of the hinge system and not the alignment of the vehicle. A load test in the verticaldirection was evaluated and ultimately rejected except for back doors. Since a large number ofdoor openings occur during vehicle rollovers, it was suggested that perhaps a load test in thevertical direction would help reduce these types of openings. However, it was ultimatelydetermined that the addition of a load test conducted in a direction orthogonal to the existing testscould not be justified at the present time. Those countries concerned about protecting againstrollover crash door openings may determine that such a test would be useful outside the context ofthe gtr.ECE/TRANS/180/Add.1page 10(iii) Inertial TestA dynamic inertial test requirement was added to the gtr, as an option to the inertial calculation. There are provisions for this type of testing in both the UNECE and North American regulations, but there is no specified test procedure. A test procedure was developed based on the testing currently conducted for the UNECE requirement and validated by the United States of America and Canada. In addition to the longitudinal and transverse tests, tests in the vertical direction were considered. Conducting the inertial test in the vertical direction is feasible, but it is much more difficult to conduct than the tests in the longitudinal and transverse directions. Since the most common failure mode demonstrated in the inertial tests conducted by Canada was in the direction of door opening, it was determined that a test in the vertical direction appeared to be beneficial only for back door designs, which commonly open in the vertical direction. However, those countries concerned about protecting against rollover crash door openings may determine that such a test would be useful outside the context of the gtr.(iv) New Combination Component TestThe United States of America developed a new combination test procedure for hinged side doors that is representative of the combination of longitudinal compressive and lateral tensile forces that occur in real-world latch failures. Currently, no regulation, directive, or international voluntary standard has such a requirement, although it is possible that a test developed by one vehicle manufacturer may be suitable for substitution once it has been fully evaluated and a benefits correlation has been conducted.Examples of the types of crashes in which forces addressed by the combination test could occur are crashes in which either the front or the rear of the vehicle is impacted (including in an offset mode). The proposed combination test procedure was a static bench test capable of evaluating the strength of the latching systems and designed to detect fork bolt detent bypass failures. No other test procedure within the gtr simulates these types of latch failure conditions.In the combination test, the latch is mounted on a flat steel plate that moves horizontally and the striker is mounted on a vertically moving ram device. During the test, the latch and striker, while in their primary coupled position, are simultaneously moved such that lateral tension (i.e., force applied perpendicularly to the coupled latch and striker) and longitudinal compressive forces (i.e., force applied against the latch toward the striker) are applied at their interface.The required forces for the primary position of the hinged side door latching systems would be simultaneous forces of 16,000 N longitudinal compressive force and 6,650 N lateral tensile force. The longitudinal force application device is moved at a rate of one centimeter per minute until the longitudinal force is achieved.There is widespread support for a test that addresses the door failure modes represented by this test. However, in some vehicles, the test setup is such that the striker cannot interface with the faceplate of the latch, rendering the test meaningless. While it is possible to modify the striker portion of the latch system so that the test can be conducted, there is strong concern regarding the adoption of this type of procedure and its potential for enforceability questions.The adoption of the combination test into the gtr is not supported at this time due to the technical difficulties in conducting the test. Instead, the Working Party delegates and representatives will continue to review work on the modification of the United States of America-based procedure, or the development of a new procedure, to capture the benefits associated with a test addressing door failures due to simultaneous compressive longitudinal and tensile lateral loading of latch systems in real world crashes. Any acceptable procedure developed could then be added to the gtr as an amendment.(v) Door HingesBoth the UNECE and North American regulations have the same load testing requirements for door hinges. The current side door requirements for hinges, which are based on SAE Recommended Practice J934, Vehicle Passenger Door Hinge Systems, appear to test adequately the strength and design of door hinges. The United States of America’s comprehensive analysis of its data and possible failure modes has not revealed problems with door hinges. Accordingly, these requirements have been included in the gtr. The current UNECE requirements only allow for the hinges to be mounted on the forward edge in the direction of travel. This requirement was based on the safety concern of a possible inadvertent opening while the vehicle is in motion. This requirement, as stated, was found to be design restrictive and the safety concerns were resolved by developing text to regulate the design and not prohibit it.(vi) Hinged Side Door System Tests (Full Door Tests)A new series of test procedures was designed to simulate real world door openings in crashes. These tests consist of door-in-frame quasi-static (full door) tests in both longitudinal and lateral directions, independent from the door system.The lateral full door test is designed to simulate latch failures in crashes that produce outwards forces on the door (i.e., through occupant loading or inertial loading) such as side crashes that result in vehicle spin and rollover. The longitudinal full door test is designed to simulate a collision in which the side of the vehicle is stretched, leading to the possibility that the striker could be torn from its mated latch (i.e., far side door in side impacts, and front and rear offset crashes on the opposite side door).The inclusion of the full door tests in the gtr was not supported because the tests raise concerns about unduly restricting door designs, developing a repeatable and enforceable test procedure, and addressing door openings under real world conditions. Because of the current UNECE requirement for both the component tests and a door closure requirement in dynamic tests, there is some question as to whether a full door test provides any additional value. In an analysis of the proposed tests using its FARS and NASS databases, the United States of America was unable to correlate the proposed tests with a reduction on door openings in real world crashes at a level that was statistically significant.The contemplated test procedures were evaluated and concerns were expressed that the new procedure will end up being unduly design restrictive, given the limitations of the test frame. For example, it may be that multiple test frames would be required to ensure an appropriate "fit" between the door and the test frame. This is because placement of the test load relative to the latch mechanism may be sufficiently different to produce significantly different results, andbecause door specific holes must be drilled into the test frame. Additionally, the test frame may not adequately address new latch designs that may be mounted in non-traditional locations. Likewise, the procedure does not allow manufacturers the benefit of non-latch attachments that are primarily used for side impact purposes but also may have a positive effect on door closure. Concerns were voiced that conducting the proposed tests on a test frame rather than on the full vehicle is impractical because not all loads can be applied to a closed door. However, it may be possible to cut the door frame and attach it to the test fixture, although such an approach may not fully replicate the actual door-in-frame as installed in the vehicle since cutting the door frame may change its characteristics. Such an approach may address the fit between the latch and striker, as well as the physical characteristics of the door and the doorframe. Accordingly, it was finally agreed not to include these proposals.(vii) Side Sliding Doors IssuesThe requirements and test procedures in both UNECE Regulation No. 11 and the North American standards for the track and slide combinations of side sliding doors are included in the gtr. The latch/striker system requirements of UNECE Regulation No. 11 are also included. However, neither regulation has a detailed full vehicle sliding door test procedure that simulates real world door openings in crashes.Simply testing the strength of the latch fails to fully account for the design of a sliding door. The current regulations for hinged doors adequately address door retention components because they test both the latch system and the hinge system. Since a sliding door has no hinges, only the latch is evaluated. The lack of a test for retention components other than the latch is an obvious weakness in the existing standards. Yet evaluating these components through a bench test would be impossible. The retention components simply are not amenable to a component test. The full-door test overcomes the lack of a component test similar to the hinge test for other doors by evaluating all retention components while the door interfaces with the doorframe.The procedure involves a full vehicle test in which a sliding door is tested by applying force against the two edges of the door. The test setup is initiated by placing two loading plates against the interior of the door. The loading plates are placed adjacent to the latch/striker system located at the door edge. If the door edge has two latch/striker systems, the loading plate is placed between the two systems. If a door edge does not have a latch/striker system, the loading plate is placed at a point midway along the length of the door edge. An outward lateral force of 18,000 N total is then applied to the loading plates, placing force against the two door edges. A test failure would be indicated by a 100 mm separation of the interior of door from the exterior of the vehicle’s doorframe at any point or either force application device reaching a total displacement of 300 mm. The gtr requires that there be no more than 100 mm of separation, even if the latch system does not fail, because, unlike hinged doors, the configuration of sliding doors allows for separation of the door from the frame without the latch system failing. The 100 mm limit is based on a commonly used measurement for maximum allowable open space in the United States of America and Canada for school bus opening requirements.The sliding door test procedure specifies that the test be conducted with force application devices that, when installed as part of the test setup, are each capable of reaching a total displacement of at least 300 mm after placement of the loading plates against the interior of the door. Under the test,。

GTR(全球统一汽车技术法规)介绍

GTR(全球统⼀汽车技术法规)介绍GTR技术法规介绍来源:全国汽车标准化技术委员会1.GTR技术法规的制定组织和《1998年协定书》GTR法规全称为全球统⼀汽车技术法规,由联合国世界车辆法规协调论坛(UN/WP29)负责制定发布,WP29原为联合国欧洲经济委员会内陆运输委员会下属的车辆结构⼯作组,在《1958年协定书》的框架下制定并实施ECE汽车技术法规,从20世纪80年代初开始,随着经济全球化的到来,许多国家和地区的政府开始认识到各⾃为政的汽车技术法规体系阻碍了汽车产品在全球范围内的⾃由流通,限制并阻碍了商品经济规律应起的作⽤,于是由国际上⼀些汽车⼯业发达国家牵头,开始进⾏国际汽车技术法规的协调与统⼀的⼯作,以打破世界各国、各地区已形成的汽车技术法规这⼀贸易技术壁垒。

在当时情况下,联合国欧洲经济委员会车辆结构⼯作组(UN/ECE/WP29)成了开展这种世界范围内汽车技术法规协调和统⼀⼯作的主要组织。

WP29于1998年6⽉25⽇制订《全球汽车技术法规协定书》[1],因此该协定书也就简称为《1998年协定书》。

世界各国以此协定书为法律框架,共同制修订全球统⼀的汽车技术法规。

该协定书在法律地位上明确原UN/ECE/WP29(联合国欧洲经济委员会车辆结构⼯作组)作为开展全球汽车技术法规协调和统⼀⼯作的国际组织,UN/ECE/WP29的名称随之更改为:“世界车辆法规协调论坛”(World Forum for Harmonization of Vehicle Regulations),仍简称为WP29,开始按照《全球汽车技术法规协定书》中规定的程序规则制定全球统⼀的汽车技术法规,到⽬前,《1998年协定书》的正式缔约⽅共计31个[2]。

历史之所以选择UN/ECE/WP29来开展全球范围内的汽车技术法规协调统⼀⼯作,其原因为:①UN/ECE/WP29成功运作《1958年协定书》,具有开展国际汽车技术法规统⼀⼯作的技术基础;②UN/ECE/WP29的⼴泛参与性,使其具有开展国际汽车技术法规统⼀⼯作的技术基础。

GTR_TYRE_第21_次会议围绕六大议题展开讨论

20综述SUMMARYGTR TYRE 第21次会议围绕六大议题展开讨论作者 杨 振 谢东明2019年1月21~22日,轮胎全球技术法规(GTR TYRE )第21次会议在日内瓦召开。

加拿大交通部、美国高速公路安全管理局(NHTSA )、俄罗斯国家汽车工程研究院(NAMI )、日本汽车标准化国际中心(JASIC )、中国汽车技术研究中心有限公司(CATARC )等政府及政府相关研究机构,以及美国轮胎制造商协会(USTMA )、欧洲轮胎轮辋技术组织(ETRTO )、日本汽车轮胎协会(JATMA )、印度机动车辆研究协会(ARAI )等国际组织的专家共计20余人参加了会议。

Andrei V. Bocharov 博士作为GTR TYRE 第二阶段法规协调非正式工作组主席主持了本次会议,ETRTO 秘书长Nicolas deMahieu 担任会议秘书。

据了解,2017年在莫斯科召开的GTR TYRE 第16次工作组会议上,中国代表团将中国轮胎国家标准体系成功导入GTR ,并就第二阶段轮胎法规协调内容组织行业专家搭建系统框架。

至此,美国FMVSS 、联合国UN ECE 、中国GB 三大轮胎法规体系成为GTR 法规协调的主要方向。

GTR TYRE 第二阶段法规协调主要方向是制定开发UN GTR No.16第二修正案,主要围绕轻型载重汽车轮胎(LT/C )耐久试验和引入全球轮胎标识,以及对磨耗标识、轮胎尺寸、高速试验、耐久试验、低气压试验等内容进行协调。

其中,高速、耐久、低气压测试在联合国UN ECE 及美国FMVSS 两大法规体系下存在较大差异,中国标准溯源ISO ,但在具体测试内容上又不同于以上两大标准体系,如何在三大标准法规体系下进行兼容性协调,成为GTR TYRE IWG (非正式工作组)面临的挑战。

会议第一项议题回顾并批准了2018年10月在比利时布鲁塞尔召开的第20次会议技术结论(TYREGTR-20-15)。

GTR简介

GTR简介

GT-R 一代1969年2月左右1969年至1972年间创下50场不败记录,因此成为性能车迷心目中的战神。

车型编号PGC10 & KPGC10 (双门版本) 引擎1989CC 直列式6缸DOHC自然吸气引擎最大马力160匹最大扭力180N.m 驱动系统FRGT-R 二代1973年1月推出外型采用以往的造型,前后四圆灯设计,但由于车体大幅增大,而动力单元基本没变。

造成马力重量比数值的不佳,而这也成为其在赛道上失利的主要原因。

加之石油危机,性能车种需求量下滑,因此而停产。

车型编号KPGC110 引擎S20 2.0L引擎(与一代GT-R相同) 驱动系统FRGT-R 三代1989年8月推出继承了日产著名赛车系列SKYLINE血统,配合最新技术,夺得"无敌战神"及"公路之王"的美誉,因此R32是GT-R系列车中性能取向最纯粹的版本。

头文字D中中里毅便是驾驶车型编号BNR32 引擎RB26DETT 2568cc twinturbo最大马力280匹(日本马力上限) 最大扭矩360N.m 驱动系统4WD GT-R32的动力搭配令当时可以说无人能敌,也因此在赛道重新回到了王者地位。

如在日本29场连胜。

43934的销售量对于一款纯粹性能趋向的日系跑车而言确实是不错的表现,三代也是GT-R系列车型中卖得最多的一代车型。

GT-R 四代1995年1月推出车型编号BCNR33 引擎RB26DETT 2568cc twinturbo最大马力280匹(日本马力上限) 最大扭矩375N.m(扭力较旧款提升15N.m) 驱动系统4WD R33 GT-R在各方面都有所进步,但在整体战斗力方面,其实并不如上代R32 GT-R来的优秀。

较为有说服力的说法是四代GT-R出于市场销售的表现而作了妥协与折中。

GT-R 五代1999年1月推出车型编号BNR34 引擎RB26DETT 2568cc twinturbo最大马力280匹(日本马力上限) 最大扭矩400N.m(扭力较旧款提升25N.m) 驱动系统4WDGT-R 六代2007年10月推出车型编号GT-R R35 引擎形式V6 排气量(c.c.) 3,799 压缩比9.0 最大马力(hp/rpm) 480/6400 最大扭力(kgm/rpm) 60.0/3200~5200 马力重量比(kg/hp) 3.625 驱动方式AWD 排档型式序列式六速自手排长宽高(mm) 4650*1895*1370车重(kg) 1740 油箱容量(l) 74 2010 NISSAN GT-R (CBA-R35)引擎型号:VR38DETT 引擎位置驱动方式:前中置(变速箱位于后桥)ATTESA E-TS全轮驱动(AWD)最大马力(匹):485(官方公布数据)最大扭力(牛-米):588 车体尺寸(长宽高mm):4650×1895×1370 车重(kg):1750 最高速度(km/h):310 0至100公里加速(秒):3.5 GTR35 Switzer P800 引擎形式V6 排气量(c.c.) 3,799 压缩比9.0 最大马力(hp/rpm) 800/6400 最大扭力(kgm/rpm)94.8/3200~5200 0至100公里加速2.9(秒) 曾经有50场连赢不败纪录,5次连胜JTCC总冠军。

GTR技术法规介绍
来源:全国汽车标准化技术委员会
1.GTR技术法规的制定组织和《1998年协定书》
GTR法规全称为全球统一汽车技术法规,由联合国世界车辆法规协调论坛(UN/WP29)负责制定发布,WP29原为联合国欧洲经济委员会内陆运输委员会下属的车辆结构工作组,在《1958年协定书》的框架下制定并实施ECE汽车技术法规,从20世纪80年代初开始,随着经济全球化的到来,许多国家和地区的政府开始认识到各自为政的汽车技术法规体系阻碍了汽车产品在全球范围内的自由流通,限制并阻碍了商品经济规律应起的作用,于是由国际上一些汽车工业发达国家牵头,开始进行国际汽车技术法规的协调与统一的工作,以打破世界各国、各地区已形成的汽车技术法规这一贸易技术壁垒。

在当时情况下,联合国欧洲经济委员会车辆结构工作组(UN/ECE/WP29)成了开展这种世界范围内汽车技术法规协调和统一工作的主要组织。

WP29于1998年6月25日制订《全球汽车技术法规协定书》[1],因此该协定书也就简称为《1998年协定书》。

世界各国以此协定书为法律框架,共同制修订全球统一的汽车技术法规。

该协定书在法律地位上明确原UN/ECE/WP29(联合国欧洲经济委员会车辆结构工作组)作为开展全球汽车技术法规协调和统一工作的国际组织,UN/ECE/WP29的名称随之更改为:“世界车辆法规协调论坛”(World Forum for Harmonization of Vehicle Regulations),仍简称为WP29,开始按照《全球汽车技术法规协定书》中规定的程序规则制定全球统一的汽车技术法规,到目前,《1998年协定书》的正式缔约方共计31个[2]。

历史之所以选择UN/ECE/WP29来开展全球范围内的汽车技术法规协调统一工作,其原因为:
①UN/ECE/WP29成功运作《1958年协定书》,具有开展国际汽车技术法规统一工作的技术基础;
②UN/ECE/WP29的广泛参与性,使其具有开展国际汽车技术法规统一工作的技术基础。

2. GTR法规制修订成果
经过十多年的努力,WP29在《1998年协定书》框架下建立全球统一的汽车技术法规体系的工作成果斐然,截止到2010年1月1日,已有12项成果出台,包括11项全球统一汽车技术法规(GTR)
和一项规范性技术文件(S.R.1)。

具体项目见表1:
表1 WP29已出台的GTR项目及其修订情况
3.GTR法规的重要性
长期以来,对于世界汽车行业而言,只有统一的国际标准,而技术法规一直是由各国各地区自行制定实施,从来没有统一的国际汽车技术法规,《1998年协定书》和GTR法规的出台,彻底打破了这一格局,全球不同汽车技术法规之间的协调工作有了法律依据、固定的渠道和程序,同时也有了正式的成果体现。

按照《1998年协定书》的规定,在GTR的表决中采取一票否决制,即每一项GTR法规的出台,必须获得所有参与表决的缔约方的全体一致通过,有任何一个缔约方反对,
该GTR草案就不能被通过,因此获得通过的每一项GTR法规都是全体缔约方共同协调、一致认可的结果,为今后在全球推广实施奠定了基础。

《1998年协定书》同时又规定,某项GTR草案一旦获得缔约方的一致通过,即成为全球性技术法规,所有对该GTR法规投赞成票的缔约方有义务争取迅速将该GTR法规引入各自国家或地区的法律或法规体系中。

并将是否采用该GTR法规(包括接受符合该GTR法规的产品),以及开始采用GTR法规的日期和其它相关情况以书面形式上报联合国。

因此GTR法规出台后,不同的国家和地区往往都积极以各种不同的方式将GTR法规的相关内容引入自身的汽车技术法规中,如欧盟常常采取先根据GTR法规修改ECE法规,再按照ECE法规修改与之相对应的EEC/EC指令,或直接采用该ECE法规的方式来采用GTR法规,美国则直接修改其自身的汽车技术法规来达到采用GTR法规的目的。

我国也不例外,近年来,我国根据汽车产业和标准化工作发展的实际情况和需要,在我国汽车标准的制修订工作中积极采用GTR,目前已采用GTR9制定我国国家推荐性标准:GB/T 24550-2009 汽车对行人的碰撞保护,该标准于2009年10月30日发布,2010年7月1日实施,今后将根据发展情况将其转化为强制性国家标准。

2010年年初,我国启动了参照GTR8“电子稳定控制系统(ESC)”制定我国标准的工作,计划2010年—2011年完成该标准的制定,该项目同行人保护标准一样,将先制定为推荐性国家标准,今后再过渡为强制性国家标准。

此外,在我国2009年的国标制修订计划中,已将GB15086—2006“汽车门锁及车门保持件的性能要求和试验方法”的修订列入计划,该项目的修订将参照采用GTR1。

在摩托车标准化工作领域内,2009年年底,在启动我国摩托车排放第4阶段标准的制定工作中,已考虑将GTR2(WMTC)的相关内容纳入到我国的标准中。

由此可见,我国企业充分掌握和了解GTR法规的发展动态及其具体技术内容,有助于了解国际汽车技术法规的最新发展状态,紧跟国际汽车技术法规发展的步伐,同时也了解和掌握包括我国在内的整个国际汽车市场技术法规的发展方向,使自己的产品能更好地适应整个国际汽车市场的要求。
