To provide a power window control device with a simple configuration that prevents erosion on electric contacts during operation when immersing in conductive liquid.SOLUTION: A control IC 10AP for a general-purpose microcomputer 10A controls a motor drive element 10B so as to detect voltage changes for one terminal of an UP switch 14A and one terminal of a DOWN switch 14B and rotate a power window motor 30. In addition, the general-purpose microcomputer 10A controls an LED driver 10AD when immersed in conductive liquid so as to let a current EC1 flow into an LED 14C for a short time. This lets a current EC2 flow into the UP switch 14A and the DOWN switch 14B to temporarily compensate a decrease in voltage for one terminal of the UP switch 14A and one terminal of the DOWN switch 14B due to short-circuit paths 60A and 60B caused by immersion in conductive liquid.SELECTED DRAWING: Figure 2
【課題】導電性液体への浸漬時の動作で電気接点の侵食が抑制される簡素な構成のパワーウィンドウ制御装置を提供する。【解決手段】汎用マイコン１０Ａの制御ＩＣ１０ＡＰは、ＵＰスイッチ１４Ａの一端及びＤＯＷＮスイッチ１４Ｂの一端の各々の電圧変化を検出してパワーウィンドウモータ３０を回転させるように、モータ駆動素子１０Ｂを制御する。また、汎用マイコン１０Ａは、導電性液体の浸漬時に、ＬＥＤ１４Ｃに電流ＥＣ１を短時間通電するようにＬＥＤドライバ１０ＡＤを制御することにより、ＵＰスイッチ１４Ａ及びＤＯＷＮスイッチ１４Ｂに電流ＥＣ２を通電させて、導電性液体の浸漬で生じた短絡路６０Ａ、６０ＢによるＵＰスイッチ１４Ａの一端及びＤＯＷＮスイッチ１４Ｂの一端の各々の電圧低下を一時的に補填する。【選択図】図２
