The invention relates to the technical field of vehicles, in particular to a motor stalling protection method and device for a rearview mirror, a vehicle and a program product, and the method comprises the steps: obtaining a first adjustment instruction of a lens of the rearview mirror, and determining a target adjustment direction of the lens based on the first adjustment instruction; if the duration that the position difference value between the current position of the lens and the position at the last moment is smaller than or equal to a first position tolerance threshold value is greater than a preset duration, judging whether the adjustment of the lens is finished within a first preset time; and if the adjustment of the lens is not finished within the first preset time, judging that the motor is in a locked-rotor state in the target adjustment direction, and controlling the motor to stop running. Therefore, the problem that an existing locked-rotor strategy is only carried out for the folding and unfolding motor and the locked-rotor processing of the lens adjusting motor is neglected is solved, the effective protection on the locked-rotor of the rearview mirror motor is optimized, and the potential safety hazard and the economic loss caused by the locked-rotor of the motor are avoided.
本申请涉及车辆技术领域,特别涉及一种后视镜的电机堵转保护方法、装置、车辆及程序产品,方法包括:获取后视镜的镜片的第一调节指令,并基于第一调节指令确定镜片的目标调节方向;若镜片的当前位置与上一时刻位置的位置差值小于或等于第一位置容差阈值的持续时长大于预设时长,则判断在第一预设时间内镜片是否调节结束;若在第一预设时间内镜片未调节结束,则判定电机在目标调节方向上处于堵转状态,并控制电机停止运行。由此,解决了现有的堵转策略往往只针对折叠展开电机进行,忽视了镜片调节电机的堵转处理的问题,优化了对后视镜电机堵转的有效保护,避免电机堵转带来的安全隐患和经济损失。
