To make it possible to grasp the margin of washer liquid with a simple system configuration without providing a plurality of washer level sensors.SOLUTION: The amount of washer liquid used is calculated from a motor current value and a motor energization time by a microcomputer 31. The amount of remaining washer liquid is estimated by subtracting the amount used after the amount of remaining washer liquid reaches a predetermined value, from the predetermined value. As a result, it becomes possible to grasp the margin of the washer liquid with a simple system configuration without providing a plurality of washer level sensors 20. In addition, by providing notification of the use time limit of the washer liquid, a driver can be made to grasp the margin of the washer liquid, and can be urged to replenish the washer liquid before the washer liquid is exhausted.SELECTED DRAWING: Figure 1

    【課題】ウォッシャレベルセンサを複数備えることなく、簡素なシステム構成でウォッシャ液の余裕を把握することを可能とする。【解決手段】マイコン31にて、モータ電流値とモータ通電時間からウォッシャ液の使用量を算出し、ウォッシャ液の残量が所定値になってからの使用量を所定値から差し引くことでウォッシャ液の残量を推定する。これにより、ウォッシャレベルセンサ20を複数備えることなく、簡素なシステム構成でウォッシャ液の余裕を把握することが可能となる。また、ウォッシャ液の使用期限を報知することで、ドライバにウォッシャ液の余裕を把握させられ、ウォッシャ液が枯渇する前にウォッシャ液の補充を促すことも可能となる。【選択図】図1
