To control, with an inexpensive configuration, an injection direction and an injection quantity of a washer liquid in accordance with the position of a wiper blade for a wiping operation.SOLUTION: A washer control signal generating circuit 106 generates a washer injection quantity control signal and a washer injection direction control signal, from a signal indicating a change in rotation angle of the output shaft of a wiper motor 18 detected by a rotation angle sensor 54. The washer injection quantity control signal makes a quantity of injected washer liquid maximum when a wiper blade starts a wiping operation from one inverting position to the other inverting position, makes it smaller when the wiper blade approaches the other inverting position, makes it maximum when the wiper blade starts a wiping operation at the one inverting position after inverting the wiping operation at the other inverting position, and makes it smaller when the wiper blade approaches the one inverting position. The washer injection direction control signal switches an advancing direction of the wiper blade after the injecting direction of the washer liquid is inverted when the wiping operation of the wiper blade is inverted at one of the two different inverting positions.SELECTED DRAWING: Figure 2

    【課題】低廉な構成で、払拭動作するワイパブレードの位置に応じてウォッシャ液の噴射方向及び噴射量を制御する。【解決手段】ウォッシャ制御信号生成回路106は、ウォッシャ液の噴射量を、ワイパブレードが一方の反転位置から他方の反転位置に払拭動作を開始する際に最大でワイパブレードが他方の反転位置に近付くに従って少なくなり、ワイパブレードが他方の反転位置で払拭動作を反転させて一方の反転位置に払拭動作を開始した際に最大でワイパブレードが一方の反転位置に近付くに従って少なくするウォッシャ噴射量制御信号、及び異なる2つの反転位置のいずれかでワイパブレードの払拭動作を反転させた際に、ウォッシャ液の噴射方向を反転後のワイパブレードの進行方向に切り替えるウォッシャ噴射方向制御信号を、回転角センサ54が検出したワイパモータ18の出力軸の回転角の変化を示す信号から生成する。【選択図】図2
