The invention relates to the technical field of automobile control, and particularly discloses a backup anti-lock control method and system based on ABS decentralized control and a vehicle. The method comprises the steps that vehicle acceleration signals, wheel speed signals of all wheels and brake pedal stroke signals are continuously collected; according to the vehicle acceleration signal and the wheel speed signal of each wheel, whether a single wheel of the vehicle is in a locked state or not is judged; when a single wheel of the vehicle is in a locked state, whether the vehicle executes a first anti-lock control strategy or not is judged according to the acceleration signal of the vehicle and the wheel speed signal of each wheel; if the vehicle does not execute the first anti-lock control strategy, a fault activation signal is generated, and the vehicle is controlled to execute the second anti-lock control strategy. According to the method, the anti-lock function of a single wheel can be achieved, function redundant backup is increased, the safety performance of the vehicle is improved, meanwhile, a main cylinder oil outlet pipe is directly connected to a wheel edge brake, and the service life of the vehicle is prolonged. System arrangement space is saved; and oil pipe length is reduced.
本申请涉及汽车控制技术领域,具体公开了一种基于ABS分散控制的备份防抱死控制方法、系统及车辆,方法包括持续性采集车辆加速度信号、各个车轮的轮速信号以及制动踏板行程信号;根据车辆加速度信号以及各个车轮的轮速信号,判断车辆是否出现单车轮抱死状态;当车辆出现单车轮抱死状态时,根据车辆加速度信号以及各个车轮的轮速信号,判断车辆是否执行第一防抱死控制策略;若车辆未执行第一防抱死控制策略,生成故障激活信号并控制车辆执行第二防抱死控制策略,本申请方法可以使单轮实现防抱死功能,增加功能冗余备份,提高车辆安全性能,同时实现主缸出油管直接到轮边制动器,节约系统布置空间和减少油管长度。
