WIPER DEVICE FOR VEHICLE AND METHOD FOR CONTROLLING WIPER DEVICE FOR VEHICLE

WIPO Patent Application WO/2017/122643

A1

The present invention reduces delay in the extending and retracting of a wiper arm, which are synchronized with reciprocating action of the wiper arm. A microcomputer 58 controls the rotational angle of an output shaft of a second motor 12 on the basis of a rotational angle map in which the timing of rotational control for the output shaft of the second motor 12 relative to the rotational angle of an output shaft of a first motor 11 is quickened, the rotational angle map being stored in a memory 60, and on the basis of the actual rotational angle of the output shaft of the first motor 11. The microcomputer 58 thereby causes the output shaft of the second motor 12 to rotate forward, and moves a fifth axis line L5, which is the supporting point of a passenger-seat-side wiper arm 35, towards a corner above the passenger-seat side on a windshield glass 1, while rotating the output shaft of the first motor 11 forward and moving a passenger-seat-side wiper blade 36 from a lower reversed position P2P to an upper reversed position P1P; and the microcomputer 58 rotates the output shaft of the second motor 12 in reverse to return the position of the fifth axis line L5 to the original position until the passenger-seat-side wiper blade 36 reaches the upper reversed position P1P.
