Title:
WIPER CONTROL METHOD AND WIPER CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2021187260
Kind Code:
A
Abstract:
To set an inversion position of wiper blades by using an overrun prevention rotation stop mechanism which is not used at a normal operation.SOLUTION: A wiper device 1 has a wiper blade overrun prevention wiper operation regulation mechanism 50, and wiper control devices 10a, 10b perform the learning setting of the inversion position of the wiper blades by using a protrusion 55a of the wiper operation regulation mechanism 50 and a stopper 54a. In learning processing, a motor is operated up until the protrusion 55a interferes with the stopper 54a (S2→S6→S8), and after that, the abutment and the separation of the protrusion and the stopper are repeated up until the protrusion 55a does not abut on the stopper 54a (S7→S1→S2 and so on) while reducing an inversion target angle (S7). Then, when the protrusion 55a does not likely abut on the stopper 54a, the upper inversion position U is set on the basis of the inversion target angle at that time (S8→S10).SELECTED DRAWING: Figure 3
