The invention provides a vehicle braking control method and device, a controller and a vehicle. The method comprises the steps that in the static state of the vehicle, when the pedal depth is reduced and a motor reverse rotation signal is received, a rollback DBR parameter in the pedal releasing process is obtained, and the rollback DBR parameter comprises the mapping relation between the pedal depth and the brake system pressure; the brake system pressure corresponding to any pedal depth in the rollback DBR parameters is greater than the brake system pressure corresponding to any pedal depth in the pressure buildup DBR parameters; and according to the pedal depth and the rollback DBR parameters, the brake system pressure of the vehicle is controlled, so that the time of creeping noise in the pedal releasing process is shortened. In the method, the brake system pressure determined according to the rollback DBR parameters in the pedal release process is larger than the brake system pressure in the pedal treading process, and compared with the mode that the same DBR parameter is adopted for pressure building and release in the prior art, pressure release is faster, and creeping noise in the pedal release process is reduced.
本申请提供一种车辆制动的控制方法、装置、控制器及车辆。该方法包括:车辆静止状态下,当踏板深度减小,并且接收到电机反转信号时,获取踏板释放过程的回退DBR参数,回退DBR参数包括踏板深度和制动系统压力的映射关系,回退DBR参数中任一踏板深度对应的制动系统压力大于建压DBR参数中任一踏板深度对应的制动系统压力;根据踏板深度和回退DBR参数,控制车辆的制动系统压力,以减少踏板释放过程中蠕动噪音的时间。在本方法中,踏板释放过程根据回退DBR参数确定的制动系统压力大于踏板踩踏过程的制动系统压力,相比于现有技术中建压和释放采用同一种DBR参数的方式,压力释放的更快,减少在踏板释放过程中的蠕动噪音。
