摘要
为降低汽车研发过程的碰撞试验成本和缩短研发周期,对无牵引装置的汽车正面碰撞试验进行系统研究,论述正面碰撞试验车自主控制系统的设计.根据C-NCAP碰撞试验法规,对车辆进行了行进方向和行车速度控制的实车试验.结果表明:试验车行进方向与纵向中心线的重合度最大正负偏差分别为+95mm和-105mm,在汽车碰撞试验法规规定范围±150mm内,车速快速提高到64km·h-1后,系统仍能够保证汽车直线稳速行驶,满足现有试验法规的基本要求,具有实用性和推广价值.
In order to reduce the vehicle cost crash test and shorten the development cycle in vehicle research process,in this paper,a towingless vehicle frontal crash test is systematically studied and the autonomous control system is discussed as well.According to C-NCAP crash test standards,travelling direction control experiment and travelling speed control experiment were carried out on the vehicle.Test results indicate that,the maximum positive and negative deviations of the contact ratio between test car travelling direction and longitudinal center line are ＋95 mm and -105 mm respectively, which are within the range of ± 150 mm stipulated by car crash test regulations.Meanwhile the system is still able to en-sure the test car driving 64 km·h-1 ,which meets the basicrequirements of existing test regulations and possesses practi-cal and popular value of the system.
