Novel car window descending clamping stagnation preventing method
The invention discloses a novel method for preventing clamping stagnation during car window descending, and relates to the technical field of car window control, and the method is characterized by comprising the following steps: step 1, connecting a Hall element with a car window lifting motor and an ECU module, and setting the disappearance duration of a Hall pulse signal in a clamping stagnation state as a monitoring threshold value Ta millisecond; step 2, Hall pulse signal disappearance duration transmission; 3, the disappearance duration time of the Hall pulse signal and the monitoring threshold value Ta millisecond are compared in real time, when the disappearance duration time of the Hall pulse signal is larger than the monitoring threshold value Ta millisecond, the clamping stagnation prevention function is triggered, the car window lifting motor is closed, and otherwise, the step 1 is continued; and 4, the car window lifting motor is automatically and reversely started. According to the anti-clamping stagnation device, the orthogonal Hall waveform is obtained through the Hall element, so that when the car window descends and runs and the disappearance duration of the Hall pulse signal exceeds the monitoring threshold value Ta millisecond, motor output is immediately closed, reverse rotation is started, and therefore the purpose of effectively preventing clamping stagnation is achieved.
本发明公开了一种新型车窗下降防卡滞的方法，涉及车窗控制技术领域，其技术方案要点包括如下步骤：步骤1、将霍尔元器件与车窗升降电机和ECU模块连接，设定卡滞状态下霍尔脉冲信号消失持续时间为监测门槛值Ta毫秒；步骤2、霍尔脉冲信号消失持续时间传输；步骤3、实时比较霍尔脉冲信号消失持续时间与监测门槛值Ta毫秒，并当霍尔脉冲信号消失持续时间大于监测门槛值Ta毫秒时触发防卡滞功能，关闭车窗升降电机，否则继续步骤1；步骤4、车窗升降电机自动反向启动。本发明通过霍尔元器件获取正交霍尔波形，以在当车窗下降运行时，当霍尔脉冲信号消失持续时间超过监测门槛值Ta毫秒时，立即关闭电机输出，再启动反转，从而达到有效的防卡滞的目的。
