PROBLEM TO BE SOLVED: To provide a temperature detection system for an on-vehicle relay, in which a temperature correction to a thermistor is not inappropriately made.SOLUTION: A temperature detection system for an on-vehicle relay comprises thermistors 24A to 24C that detect temperatures of system main relays SMRB, SMRG, and SMRP. A monitor unit 20 of a relay temperature detection system is configured to, when an average value of currents IB flowing through the system main relays SMRB, SMRG, and SMRP during a prescribed period of time exceeds a threshold, add a correction value to the detection temperatures of the thermistors 24A to 24C on the basis of the current IB flowing through the system main relays SMRB, SMRG, and SMRP, and output the detection value having the correction value added as the temperature values of the system main relays SMRB, SMRG, and SMRP.SELECTED DRAWING: Figure 2

    【課題】サーミスタに対する温度補正が不適切に行われることのない、車載リレーの温度検出システムを提供する。【解決手段】車載リレー温度検出システムは、システムメインリレーSMRB,SMRG,SMRPの温度を検出するサーミスタ24A〜24Cを備える。リレー温度検出システムの監視ユニット20は、システムメインリレーSMRB,SMRG,SMRPに流れる電流IBの所定期間における平均値が閾値を超過したときに、システムメインリレーSMRB,SMRG,SMRPに流れる電流IBに基づいてサーミスタ24A〜24Cの検出値に補正値を加算し、これをシステムメインリレーSMRB,SMRG,SMRPの温度値として出力する。【選択図】図2
