The invention discloses a locked-rotor protection method, device and equipment for a rearview mirror folding and unfolding driving motor. Comprising the steps that real-time current of a rearview mirror folding and unfolding driving motor is detected, and starting current of the rearview mirror folding and unfolding driving motor is obtained; determining a locked-rotor protection threshold value according to the starting current; and when it is detected that the real-time current reaches the locked-rotor protection threshold value, the rearview mirror folding and unfolding driving motor is closed, and locked-rotor protection is conducted on the rearview mirror folding and unfolding driving motor. The locked-rotor protection threshold value is determined through the starting current obtained by detecting the real-time current of the rearview mirror folding and unfolding driving motor, the locked-rotor protection threshold value serves as a motor closing basis, locked-rotor protection of the motor is achieved, and therefore the locked-rotor protection is not affected by environmental factors during locked-rotor protection, and the service life of the motor is prolonged. And the motor can be timely and accurately turned off without adding extra hardware detection equipment, so that the damage caused by long-time stalling of the rearview mirror folding and unfolding driving motor is reduced.

    本发明公开了一种后视镜折叠展开驱动电机的堵转保护方法、装置和设备。包括:对后视镜折叠展开驱动电机的实时电流进行检测,获取后视镜折叠展开驱动电机的启动电流;根据启动电流确定堵转保护阈值;当检测到实时电流达到堵转保护阈值时,将后视镜折叠展开驱动电机进行关闭,以对后视镜折叠展开驱动电机进行堵转保护。通过对后视镜折叠展开驱动电机的实时电流检测所获取的启动电流来确定堵转保护阈值,将堵转保护阈值作为电机关闭依据,实现了对电机的堵转保护,从而在进行堵转保护时无需受环境因素影响,也无需增加额外的硬件检测设备就可以及时准确的关闭电机,减少后视镜折叠展开驱动电机长时间堵转带来的损害。
