Abstract

本发明公开了一种EPB动态制动控制方法、装置、设备、介质和车辆,其中,方法包括以下步骤:判断车辆是否进入EPB动态制动过程,若车辆进入EPB动态制动过程,则控制EPB电机停止进入EPB初始保持阶段;获取车辆的车速值和轮速值;根据车速值、轮速值输出制动控制信号,制动控制信号为夹紧使能信号或释放使能信号;若输出夹紧使能信号,则控制EPB卡钳执行夹紧循环过程;若连续输出夹紧使能信号,则对EPB卡钳连续执行夹紧循环过程的次数进行计数;若计数大于预设计数,且仍输出夹紧使能信号,则控制EPB卡钳停止执行夹紧循环过程;直至输出至少一次释放使能信号,计数清零,返回开始步骤。这样,有利于防止夹紧过度,导致卡钳损坏,造成行车危险。

The invention discloses an EPB dynamic braking control method, device, equipment, medium and vehicle, wherein the method comprises the following steps of judging whether the vehicle enters an EPB dynamic braking process, if the vehicle enters the EPB dynamic braking process, controlling an EPB motor to stop entering an EPB initial maintaining stage, obtaining a vehicle speed value and a wheel speed value, outputting a braking control signal according to the vehicle speed value and the wheel speed value, wherein the braking control signal is a clamping enabling signal or a releasing enabling signal, if the clamping enabling signal is output, controlling an EPB caliper to execute the clamping circulating process, if the clamping enabling signal is continuously output, counting the number of times the EPB caliper continuously executes the clamping circulating process, if the count is larger than a preset count and still outputs the clamping enabling signal, controlling the EPB caliper to stop executing the clamping circulating process until at least one time of releasing enabling signal is output, and resetting the count, and returning to the starting step. Thus, excessive clamping is prevented, the calipers are damaged, and driving danger is caused.
