汽车防误踩加速踏板系统的研发

摘要

为减少和防止紧急制动时误踩加速踏板此类事故的发生,利用汽车加速操作和紧急制动操作存在可分辨的角速度和角加速度的差别,设计了防误踩加速踏板系统,并对系统进行了台架试验和实车测试.结果表明,该系统缩短了汽车的制动距离,有效地防止误踩事故的发生,极大地提高了行车的主动安全性.%To avoid misoperation on accelerator pedal in emergency braking, a vehicle accelerator pedal system with misoperation prevention function is designed, taking the advantage of the perceptible differences in angular speed and acceleration between operations of acceleration and emergency braking. Both bench test and real vehicle test are conducted on the system. The results show that the system can reduce the braking distance and effectively prevent the misoperation of accelerator pedal, greatly enhancing the active safety of vehicle driving.
