The invention provides a braking system for a vehicle, a wheel end braking device and the vehicle. The brake system comprises a main controller and at least one wheel end brake device, each wheel end brake device comprises a brake motor, a brake motor controller and an actuator, and the brake motor controller is used for controlling the brake motor to output brake torque so as to drive the actuator to output friction brake force to a brake disc of the vehicle. The brake motor controller is used for responding to a brake torque signal output by the main controller, firstly controlling the brake motor to output a first brake torque and then controlling the brake torque output by the brake motor to be reduced to a second brake torque, the second brake torque is smaller than the first brake torque, and the second brake torque is smaller than the first brake torque. The difference value between the friction braking force output by the actuator driven by the first braking torque and the friction braking force output by the actuator driven by the second braking torque is smaller than a preset value, and therefore the braking performance of the braking system is guaranteed, and meanwhile a braking motor is prevented from being overheated.

    本申请提供一种用于车辆的制动系统,轮端制动装置以及车辆。该制动系统包括主控制器和至少一个轮端制动装置,每个该轮端制动装置包括制动电机、制动电机控制器以及执行器,该制动电机控制器用于控制该制动电机输出制动扭矩以驱动该执行器向该车辆的刹车盘输出摩擦制动力。该制动电机控制器用于响应于主控制器输出的制动扭矩信号,先控制该制动电机输出第一制动扭矩,再控制该制动电机输出的制动扭矩降低至第二制动扭矩,该第二制动扭矩小于该第一制动扭矩,其中,该第一制动扭矩驱动该执行器输出的该摩擦制动力与该第二制动扭矩驱动该执行器输出的该摩擦制动力的差值小于预设值,从而在保证制动系统的制动性能的同时,防止制动电机出现过热。
