摘　　要：针对汽车制动过程及制动力的测试方法进行了分析,对近年来我国制定的制动力性能检验标准的优缺点进行了阐述。指出,GB 7258—87未对整个制动过程加以控制,导致通过了检测的车辆也会出现制动甩现象;GB7258—97对初始制动阶段缺乏考虑,导致一部分合格车辆通不过检测线;GB 7258—2004标准比较科学合理。对标准中存在的不足给出了相应的解决方法。Analysis is made to vehicle＇s braking process and braking force test method, and superiorities and deficiencies of the test standards of braking force performance formulated by China in recent years are elaborated. It is pointed out in the paper that standard GB7258--87 fails to control the whole braking process, resulting in braking swerve of the vehicles which already pass test; GB7258--97 doesn＇t consider the initial braking stage, causing some qualified vehicle can not pass test; GB7258--2004 is comparatively scientific and reasonable, which gives corresponding solution to deficiencies existing in standard
