The invention discloses a method, device, equipment and medium for preventing a motor from stalling during slope slipping prevention of a vehicle, and the method comprises the steps: after a driving motor enters a stalling state, the torque of the driving motor is adjusted according to the internal temperature of the driving motor, so that the driving motor stops stalling; and after the driving motor stops locked-rotor, the torque of the driving motor is adjusted again according to the slope sliding distance of the vehicle and the temperature of the driving motor, so that the driving motor enters the locked-rotor state again. The locked-rotor phase of the driving motor is adjusted when the vehicle is prevented from sliding on the slope, overheating and damage of the driving motor caused by long-time locked-rotor of the driving motor are avoided, meanwhile, the retreating distance when the vehicle slides on the slope is controlled, and the driving safety of the vehicle and the driving experience of a user are greatly improved.
本申请公开了一种车辆防溜坡时防止电机堵转的方法、装置、设备及介质,通过在驱动电机进入堵转状态后,根据所述驱动电机的内部温度调整所述驱动电机的扭矩,使得所述驱动电机停止堵转;在所述驱动电机停止堵转后,根据车辆的溜坡距离和所述驱动电机的温度,再次调整所述驱动电机的扭矩,使得所述驱动电机再次进入所述堵转状态。实现了在车辆防溜坡时对驱动电机的堵转相位进行调整,避免了驱动电机长时间堵转造成的驱动电机过热和损坏,同时又对车辆溜坡时后退的距离进行控制,大大提升车辆的驾驶安全和用户的驾驶体验。
