The invention provides a wheel end braking device with a parking re-clamping function, a braking system and a method, relates to the field of new energy automobiles, and can be applied to pure electric vehicles and hybrid vehicles. The wheel end braking device comprises a braking unit, a parking unit and a wheel end controller. The braking unit comprises a braking motor and braking calipers, the braking motor is used for outputting braking torque to drive the braking calipers to output clamping force to a brake disc of the vehicle, and the parking unit is used for locking the braking motor. The wheel end controller responds to the situation that the difference value between the clamping force output by the braking unit and the target clamping force is smaller than the preset difference value for a preset duration, and the wheel end controller is used for controlling the parking unit to lock the braking motor. According to the scheme, the vehicle sliding risk caused by insufficient clamping force output by the brake calipers in the vehicle parking process can be reduced, and therefore the parking safety and reliability are improved.

    本申请提供一种具有驻车再夹紧功能的轮端制动装置,制动系统和方法,涉及新能源汽车领域,可应用于纯电动车辆及混动车辆。该轮端制动装置包括制动单元、驻车单元以及轮端控制器。制动单元包括制动电机和制动卡钳,制动电机用于输出制动扭矩以驱动制动卡钳向车辆的刹车盘输出夹紧力,驻车单元用于锁止制动电机。轮端控制器响应于制动单元输出的夹紧力和目标夹紧力的差值小于预设差值持续预设时长,轮端控制器用于控制驻车单元锁止制动电机。本申请的方案可以降低车辆驻车过程中由于制动卡钳输出的夹紧力不足而导致的溜车风险从而提高驻车的安全性和可靠性。
