The invention discloses a control method for a non-controller type hidden rear windscreen wiper, which comprises the following steps of: dividing a BCM (Body Control Module) control logic of the rear windscreen wiper in a working area and a BCM deviation correction control logic of the rear windscreen wiper in a non-working area according to the working condition of the rear windscreen wiper; when the wiper arm and wiper blade assembly of the rear windscreen wiper wipes out of the maximum wiping angle position, the rear windscreen wiper wipes back and forth at the non-working area power-off stop position and the working area motor reverse rotation power-on position; continuously capturing a motor pin signal of a maximum scraping angle position of the driving motor, a motor pin signal of a non-working area power-off stop position and a motor pin signal of a working area motor reverse rotation power-on position through a BCM (Body Control Module); and then the BCM controls the driving motor to be reversely electrified through the relay, so that the rear windscreen wiper forcibly reversely scrapes back to the motor working area where the initial wiping position B and the maximum wiping angle position C of the continuous wiping are located, and the normal wiping function is recovered under the control of the BCM control logic of the rear windscreen wiper in the working area.

    本发明公开了一种非控制器类隐藏式后雨刮器控制方法,按照后雨刮器所处工况,分为后雨刮器在工作区内的BCM控制逻辑,以及后雨刮器在非工作区内的BCM纠偏控制逻辑;当后雨刮器刮臂刮片总成刮出最大刮角位置时,后雨刮器在非工作区断电停靠位置与工作区电机反转通电位置来回刮刷,通过BCM连续捕捉:驱动电机的最大刮角位置的电机pin脚信号、非工作区断电停靠位置的电机pin脚信号以及工作区电机反转通电位置的电机pin脚信号;然后BCM通过继电器控制驱动电机反向通电,让后雨刮器强制反刮刮回连续刮刷初始刮刷位置B和最大刮角位置C所在的电机工作区,受到后雨刮器在工作区内的BCM控制逻辑控制,恢复正常的刮擦功能。
