Automobile tail door controller protection method and device
The invention discloses a protection method for an automobile tail gate controller. The protection method comprises the following steps: detecting a power supply voltage after the tail gate controller is powered on; judging whether the power supply voltage is power supply voltage or reverse electromotive force; and if the power supply voltage of the tail gate controller is the reverse electromotive force and the reverse electromotive force reaches the reverse breakdown voltage of the MOS tube, the two ends of the supporting rod motor are controlled to be conducted to the ground to release the reverse electromotive force. According to the scheme, the tail gate controller and related electrical components can be effectively protected, the stability and safety of the system are improved, and the after-sale cost is reduced.
本发明公开了一种汽车尾门控制器保护方法，包括：检测尾门控制器上电后的供电电压；判断供电电压是电源电压还是反向电动势；如果尾门控制器的供电电压为反向电动势且反向电动势达到MOS管反向击穿电压，则控制撑杆电机两端对地导通释放反向电动势。本方案能够有效地保护尾门控制器和相关的电气部件，提高系统的稳定性和安全性，降低售后成本。
