摘　　要：汽车后雨刮控制电路分为BCM(车身控制器)控制和非BCM控制两种,每种电路对应的电机硬件都有差异;非BCM控制成本低但是功能简单,特殊情况下停机时可能不在初始位置;BCM能通过复位信号判断雨刮进入或离开复位区,能实现精确停机,所以是目前主流的控制电路,但是需要注意控制复位区角度和定义复位信号有效值的要求,否则会出现无法停机的问题。Automotive rear wiper control circuit is divided into two kinds:BCM (body controller) control and non-BCM control,each circuit corresponding to the motor hardware is different.Non-BCM control has low cost but simple function,and may not be in the initial position when it is shut down under special circumstances.BCM can determine whether the wiper enters or leaves the reset area through the reset signal and can realize accurate shutdown,so it is the mainstream control circuit at present.However,attention should be paid to the requirements of controlling the Angle of the reset area and defining the effective value of the reset signal,otherwise the problem will not be able to stop.
