The invention provides an electronic mechanical braking system for controlling redundancy, a wheel end braking device and an electric vehicle. The electronic mechanical braking system comprises a central controller and four wheel end braking devices, each wheel end braking device comprises a wheel end controller and a braking actuator, and the wheel end controllers are used for controlling the braking actuators to output braking force to a brake disc of the electric vehicle. The central controller is used for being connected with one brake pedal sensor, and one of the four wheel end controllers is used for being connected with the other brake pedal sensor. According to the electronic mechanical braking system, one of the four wheel end controllers is used for being connected with the brake pedal sensor, and when the central controller fails, the wheel end controller connected with the brake pedal sensor can continuously control the four wheel end braking devices to brake the vehicle; therefore, the braking safety and the operation reliability of the mechanical braking system of the motor can be improved.
本申请提供了一种控制冗余的电子机械制动系统、轮端制动装置以及电动车辆。该电子机械制动系统包括中央控制器以及四个轮端制动装置,每个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。中央控制器用于连接一个制动踏板传感器,四个轮端控制器中的一个轮端控制器用于连接另一个制动踏板传感器。本申请提供的电子机械制动系统的四个轮端控制器中的其中一个用于连接制动踏板传感器,在中央控制器失效时,连接制动踏板传感器的轮端控制器可以继续控制四个轮端制动装置制动车辆,从而可以提高电机机械制动系统的制动安全性和运行可靠性。
