随着汽车行业的快速发展,汽车作为日常交通工具被广泛普及,车辆驾驶安全性能的需求便随之而来,车辆的制动功能和驻车安全性则是其中最为重要的安全性能指标。当整车电子换挡系统出现故障时,驾驶员往往难以察觉,且因未及时识别故障而未采取主动制动,易导致车辆溜车和前冲,从而造成驾驶员和公众生命财产安全受到损害。本文提出一种驻车挡位故障的制动控制方案,通过检测到整车电子换挡系统故障后,变速器控制器判断车辆安全制动状态,并在安全制动状态下自动驻车,控制车辆保持制动状态,避免了在驾驶员未采取主动制动的情况下,车辆出现溜车和前冲问题,极大地保护了驾驶员和公众安全。

With the rapid development of the automotive industry, cars have been widely popularized as daily means of transportation, and the demand for vehicle driving safety performance has emerged accordingly. Among them, the braking function and parking safety of vehicles are the most important safety performance indicators. When the electronic gear shifting system of the entire vehicle malfunctions, drivers often fail to notice it. Moreover, due to the failure to identify the fault in time, they do not take active braking measures, which can easily lead to the vehicle rolling back and surging forward, thereby causing damage to the lives and property of drivers and the public. This paper proposes a braking control scheme for parking gear faults. After detecting faults in the vehicle's electronic shift system, the transmission controller determines the vehicle's safe braking state and automatically parks the vehicle in this state to control it to maintain braking. This avoids the problem of the vehicle rolling back and sudden acceleration when the driver does not take active braking measures. It has greatly protected the safety of drivers and the public.
