PROBLEM TO BE SOLVED: To make it possible to monitor a lighting state of a direction indicator lamp with a good accuracy.SOLUTION: A display device M for a vehicle, which is a control device M for a direction indicator lamp which blinks a direction indicator lamp 11, comprises: driving means 2 which outputs a first electric current and outputs a first voltage proportional to the first electric current to the direction indicator lamp 11; control means 6 which outputs a changeover signal, which causes the driving means 2 to switch on and off the output of the first electric current, and determines a state of the direction indicator lamp 11 on the basis of the state of the changeover signal and a comparison result between the first voltage and a prescribed threshold; and temperature detection means 5 which detects a temperature of the driving means 2. The control means 6 corrects the first voltage or the prescribed threshold on the basis of the temperature detected by the temperature detection means 5.SELECTED DRAWING: Figure 1
【課題】 方向指示灯の点灯状態を精度良く監視する。【解決手段】 本発明の一実施形態である車両用表示装置Mは、方向指示灯11を点滅表示する方向指示灯の制御装置Mであって、方向指示灯11に第1電流を出力すると共に第1電流に比例した第1電圧を出力する駆動手段2と、駆動手段2に第1電流の出力をオン/オフさせる切替信号を出力すると共に切替信号の状態と第1電圧と所定の閾値との対比結果とに基づいて方向指示灯11の状態を判定する制御手段6と、駆動手段2の温度を検出する温度検出手段5と、を備え、制御手段6は、温度検出手段5が検出した温度に基づいて第1電圧または所定の閾値を補正する。【選択図】 図1
