CONTROL METHOD FOR WIPER DEVICE

摘要

PROBLEM TO BE SOLVED: To ensure driver's field of view even when a system causes a failure in a wiper device in which right and left blades are driven by individual motors. SOLUTION: In the opposing wiping type wiper device, wiper blades on a driver's seat side and on a passenger seat next to driver side are driven by motors 3a, 3b individually. The motor 3a is directly turned ON and OFF by a wiper switch 42 and drives the wiper blade on the driver's seat side independently without interlocking with the operation of the motor 3b. The motor 3b is controlled by a wiper drive controller 10, and its operation is controlled based on a rotation signal of the motor 3a to prevent the interference of the wiper blades on the driver's seat side and on the passenger seat next to the driver seat side. Even if the wiper blade on the passenger seat next to the driver seat side stops due to a failure, the wiping operation by the wiper blade on the driver's seat side is maintained to ensure driver's field of view.
