Abstract
A method (and apparatus) includes that a duty ratio of a driving voltage output to each wiper motor be required to be set according to several conditions. That is, while each wiper blade is moved in an interval from a starting position to a predetermined first wiping position in an upward operation, the duty ratio of a wiper motor on a driver's seat side is set so that the duty ratio is larger than the duty ratio of a wiper motor on a passenger seat side. Also, while each wiper blade is moved in another interval from each upper return position to a predetermined second wiping position in a return operation, the duty ratio of the wiper motor on the passenger seat side is set so that the duty ratio is larger than the duty ratio of the wiper motor on the driver's seat side.
