The invention discloses a vehicle braking torque compensation method, medium, equipment and device, and the method comprises the steps: obtaining the static operation current of a vehicle and a firstvehicle state parameter, and judging whether the vehicle enters a braking state or not according to the first vehicle state parameter; if the vehicle enters the braking state, judging whether a battery of the vehicle is allowed to return power or not currently; if the battery of the vehicle does not allow power return at present, acquiring bus current, and judging whether the bus current is smaller than vehicle static operation current or not; if the bus current is smaller than the vehicle static operation current, acquiring a second vehicle state parameter, and calculating compensation torqueaccording to the second vehicle state parameter; and compensating vehicle braking torque according to the compensation torque. The vehicle braking torque can be reasonably controlled under the condition that the vehicle battery does not allow power return, and the battery overcharge fault caused by unreasonable torque control is avoided.

    本发明公开了一种车辆制动扭矩补偿方法、介质、设备及装置,其中方法包括:获取车辆静态运行电流和第一车辆状态参数,并根据所述第一车辆状态参数判断车辆是否进入制动状态;如果车辆进入制动状态,则判断车辆的电池当前是否允许回电;如果车辆的电池当前不允许回电,则获取母线电流,并判断母线电流是否小于车辆静态运行电流;如果所述母线电流小于车辆静态运行电流,则获取第二车辆状态参数,并根据所述第二车辆状态参数计算补偿扭矩,以及根据所述补偿扭矩对车辆制动扭矩进行补偿;能够在车辆电池不允许回电的情况下对车辆制动扭矩进行合理控制,避免因为扭矩控制不合理而导致的电池过充故障。
