Title: Control method for wiper device
Inventor: FURUSAWA TORU
IPC: B60S1/28
Filed: 2001-03-14
Abstract: PROBLEM TO BE SOLVED: To suppress overrun of a blade at an inversion position in an opposing wiping type wiper device. SOLUTION: Right and left wiper blades driven by separate motors, respectively, are reciprocated and operated so as to wipe opposingly between an upper inversion position and a lower inversion position Y. When the wiper blade exists in a limit compensation region Q set in the vicinity of the lower inversion position Y, an output of the motor is regulated to below a limit value V set in advance. Even if a motor output is increased in the vicinity of the lower inversion position Y due to the enlargement of a difference in angle between the blades, the output can be suppressed to below the limit value V. Consequently, the motor output is increased and the blades are accelerated though close to a lower inversion position Y to suppress overrunning the lower inversion position Y.
