The invention provides a wheel end braking device with a wheel speed closed-loop function, a braking system and a control method, and relates to the technical field of electric automobiles. The wheel end braking device comprises a wheel end controller and a wheel end actuator, and the wheel end controller is used for controlling the wheel end actuator to output clamping force to a brake disc of the electric vehicle in the vehicle braking process so as to brake wheels of the electric vehicle; the wheel end controller is specifically used for receiving the clamping force signal and the wheel speed signal from the central controller and controlling the wheel end actuator to output clamping force according to the clamping force signal or the wheel speed signal; wherein the clamping force signal is used for indicating the clamping force output by the wheel end braking device to the corresponding wheel, and the wheel speed signal is used for indicating the wheel speed of the wheel corresponding to the wheel end braking device. In this way, the control precision of the braking system is improved, and therefore the driving safety is improved.

    本申请提供一种具有轮速闭环功能的轮端制动装置、制动系统和控制方法,涉及电动汽车技术领域。轮端制动装置包括轮端控制器和轮端执行器,轮端控制器用于在车辆制动过程中控制轮端执行器向电动车辆的刹车盘输出夹紧力以制动电动车辆的车轮;轮端控制器具体用于:接收来自中央控制器的夹紧力信号和轮速信号,并根据夹紧力信号或轮速信号控制轮端执行器输出夹紧力;其中,夹紧力信号用于指示轮端制动装置向对应的车轮输出的夹紧力,轮速信号用于指示轮端制动装置对应的车轮的轮速。如此,提高了制动系统的控制精度,从而提高驾乘安全。
