VEHICLE WIPER DEVICE
20230046669 · 2023-02-16 · ·

In a vehicle wiper apparatus, rotation of an output shaft of a wiper motor is converted to reciprocal rotation of a pivot shaft, and a wiper member, attached to the pivot shaft, reciprocally rotates between closed and open positions. A nozzle, provided in the wiper member, sprays a cleaning fluid towards a front side in an advancing direction of the wiper member on at least one of forward and return paths of the reciprocal rotation. A washer pump supplies the cleaning fluid to the nozzle. A round-trip time of the wiper member is detected based on a detection result of a detecting unit that detects at least a state in which the wiper member is positioned in the closed position. The washer pump is controlled based on a detected round-trip time, and is operated during rotation of the wiper member on at least one of the forward and return paths.
