The embodiment of the invention provides a control method and device for a vehicle brake control system and a vehicle, the brake control system comprises a brake-by-wire system and a power domain system, and the method comprises the steps that in response to a brake request of a driver, whether the brake control system breaks down or not is detected; if the brake control system has the fault, determining the fault type of the brake control system; based on the fault type, determining a braking strategy suitable for completing the braking request; and based on the braking strategy, the vehicle is controlled to be braked, so that the actual braking deceleration generated by the vehicle meets the braking pedal feeling curve of the vehicle. According to the technical scheme provided by the embodiment of the invention, under the condition that the brake control system of the vehicle breaks down, the foot feeling of a driver does not change remarkably in the braking process of the vehicle, and therefore the driving safety of the vehicle is improved.
本申请的实施例提供了一种车辆制动控制系统的控制方法、装置及车辆,所述制动控制系统包括线控制动系统和动力域系统,所述方法包括:响应于驾驶员的制动请求,检测所述制动控制系统是否存在故障;如果所述制动控制系统存在故障,则确定所述制动控制系统存在的故障类型;基于所述故障类型,确定适于完成所述制动请求的制动策略;基于所述制动策略,控制所述车辆进行制动,以使得所述车辆产生的实际制动减速度满足所述车辆的制动踏板感曲线。本申请的实施例提供的技术方案使得在车辆的制动控制系统出现故障的情况下,车辆在制动过程中驾驶员的脚感也无显著变化,从而提升车辆的行车安全。
