Title:
WIPER DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/147140
Kind Code:
A1
Abstract:
A wiper motor control circuit performs control to cause a drive circuit to generate a voltage that eliminates a deviation between a target speed and an actual speed of an output shaft, and supply said voltage to a wiper motor, and if a state in which the deviation between the target speed and the actual speed is at least equal to a deviation threshold continues for at least a prescribed length of time, reduces the target speed, and performs control to cause the drive circuit to generate a voltage that eliminates the deviation between the reduced target speed and the actual speed of the output shaft, and supply said voltage to the wiper motor.
