The invention discloses a control system and method for an air door of an automobile air conditioner, and the system is characterized in that a CAN bus is provided with a main node; the LIN bus is provided with a plurality of air conditioner air door actuators serving as slave nodes; the CAN communication unit is used for monitoring addressing request signals sent by other slave nodes; the micro-control unit is used for responding to addressing request signals sent by other slave nodes; the problem that manual communication address setting is high in cost and prone to errors in the prior art is solved. Meanwhile, a current induction amplification unit is adopted, when the motor is locked, current changes in a motor loop are detected in real time, then a user is informed that an actuator breaks down on an interactive interface of the intelligent automobile in the form of exclamation marks, and motor locked-rotor detection and early warning are achieved.
本发明公开了一种汽车空调风门控制系统与方法,其中,所述CAN总线上设置有主节点;所述LIN总线上设置有多个作为从节点的空调风门执行器;所述CAN通信单元用于监听其他从节点发出的寻址请求信号;所述微控制单元用于响应其他从节点发出的寻址请求信号;解决了现有技术中人工设置通信地址成本高易出错的问题;同时本发明采用电流感应放大单元,当电机发生堵转时,实时检测电机回路中的电流变化,然后在智能汽车的交互界面上通过感叹号的形式来通知用户执行器发生故障,实现电机堵转检测与预警。
