The invention provides a vehicle braking control method and device, equipment and a storage medium, and the method comprises the steps: carrying out the validity judgment of the braking state of a target vehicle, and generating an electric braking request instruction when the target vehicle is in a braking failure state; then the electric braking request instruction is responded, and the electric braking maximum allowable recovery torque value of the target vehicle is calculated; and finally, braking control is conducted on the target vehicle according to the maximum allowable recovery torque value of electric braking, and the vehicle speed of the target vehicle is reduced. The braking failure condition of the vehicle can be recognized, and after the vehicle braking failure is recognized, the vehicle is actively braked and decelerated through the electric braking function of the motor, so that the vehicle is in a safe state. When the braking system of the electric automobile fails, backup braking can be achieved through the electric braking characteristic of the motor, deceleration braking can be conducted on the extreme working condition that the chassis braking system of the automobile fails, and safety threats to a driver and passengers of the automobile are reduced or avoided.

    本申请提供一种车辆制动控制方法、装置、设备及存储介质,包括:对目标车辆的制动状态进行有效性判断,并在目标车辆处于制动失效状态时,生成电制动请求指令;然后再响应于电制动请求指令,并计算出目标车辆的电制动最大允许回收扭矩值;最后根据电制动最大允许回收扭矩值对目标车辆进行制动控制,降低目标车辆的车速。本申请能够对车辆出现的制动失效状况进行识别,并且在识别发现车辆制动失效后,通过电机的电制动功能主动对车辆进行制动减速,从而使车辆处于安全状态。当电动汽车制动系统失效后,可以利用电机的电制动特性实现备份制动,能够对车辆出现底盘制动系统失效的极端工况进行减速制动,降低或避免车辆驾乘人员的安全威胁。
