The invention relates to an automobile outside rear-view mirror anti-freezing system and a control method thereof.The automobile outside rear-view mirror anti-freezing system is mainly composed of an outside rear-view mirror control mechanism, a temperature and humidity sensor, an automobile door controller and an outside rear-view mirror position sensor, the outside rear-view mirror control mechanism is used for starting the system, and the temperature and humidity sensor is used for detecting the relative humidity and temperature of the automobile body environment; the BCM/vehicle door controller is connected with the outside rear-view mirror assembly and can obtain the temperature and humidity values, judge whether the temperature and humidity values reach threshold values or not and drive an outside rear-view mirror motor in the outside rear-view mirror assembly to operate, and the outside rear-view mirror position sensor is used for recognizing whether an outside rear-view mirror is folded or unfolded in place or not after the outside rear-view mirror motor acts. According to the anti-freezing system for the automobile outside rear-view mirror and the control method of the anti-freezing system, the outside rear-view mirror can be automatically unfolded when rainwater or dew condensation occurs and the air temperature is close to the freezing point in the automobile locking and folding mode of the outside rear-view mirror, the anti-freezing function of the outside rear-view mirror in the automobile locking and closing state is achieved, and the awkward situation that the outside rear-view mirror cannot be unfolded during unlocking is avoided.

    本发明涉及一种汽车外后视镜防冻结系统及其控制方法,主要由外后视镜控制机构、温湿度传感器、车门控制器以及外后视镜位置传感器构成,外后视镜控制机构用于启动系统,温湿传感器用于检测车身环境相对湿度、温度,BCM/车门控制器与外后视镜总成相连,能获取温、湿度的数值,判断是否达到阈值,并驱动外后视镜总成内的外后视镜电机运转,外后视镜位置传感器用于在外后视镜电机动作后,识别外后视镜是否折叠/展开是否到位。本发明汽车外后视镜防冻结系统及其控制方法,使得在锁车外后视镜折叠模式下,当出现雨水或结露且气温接近冰点时,外后视镜能自动展开,实现外后视镜锁车闭合状态防冻结功能,以避免解锁时无法展开外后视镜的窘境。
