The invention provides a wheel end braking device, an electronic mechanical braking system, a braking redundancy control method and an electric vehicle. The wheel end braking device comprises a wheel end controller and a braking actuator, and the wheel end controller is used for controlling the braking actuator to output braking force to a brake disc of the electric vehicle. The wheel end controller is used for receiving a first braking control signal from the central controller or a second braking signal from the whole vehicle controller, and the first braking control signal and the second braking control signal are used for controlling the wheel end braking device to output braking force. And under the condition that the central controller fails, the wheel end controller can be controlled by the second brake control signal. According to the wheel end braking device, the electronic mechanical braking system, the braking redundancy control method and the electric vehicle, backup redundancy control of the electronic mechanical braking system is achieved under the condition that the hardware cost is not increased, and the braking safety and reliability of the electric vehicle are improved.

    本申请提供了一种轮端制动装置、电子机械制动系统、制动冗余控制方法以及电动车辆。轮端制动装置包括轮端控制器和制动执行器,轮端控制器用于控制制动执行器向电动车辆的刹车盘输出制动力。轮端控制器用于接收来自中央控制器的第一制动控制信号或者来自整车控制器的第二制动信号,第一制动控制信号和第二制动控制信号用于控制轮端制动装置输出制动力。在中央控制器失效的情况下,轮端控制器可以由第二制动控制信号进行控制。本申请提供的轮端制动装置、电子机械制动系统、制动冗余控制方法以及电动车辆在不增加硬件成本的情况下实现了电子机械制动系统的备份冗余控制,提高了电动车辆的制动安全可靠性。
