To provide a technique capable of diagnosing failures associated with a capacitance sensor.SOLUTION: A contact detection device comprises: a capacitance sensor provided in a steering wheel of a vehicle and detecting a human body contact into the steering wheel; estimating means for estimating whether the human body is in contact with the steering wheel; and diagnosing means for diagnosing failures associated with the capacitance sensor on the basis of detection results of the capacitance sensor when the estimating means estimates that the steering wheel is in contact with the human body and detection results of the capacitance sensor when the estimating means estimates that the steering wheel is not in contact with the human body.SELECTED DRAWING: Figure 6

    【課題】静電容量センサに関わる故障診断が可能な技術を提供すること。【解決手段】接触検知装置は、車両のステアリングホイールに設けられ、前記ステアリングホイールに対する人体の接触を検知する静電容量センサと、前記ステアリングホイールに人体が接触しているか否かを推定する推定手段と、前記推定手段が接触していると推定した場合の前記静電容量センサの検知結果と、前記推定手段が接触していないと推定した場合の前記静電容量センサの検知結果と、に基づいて、前記静電容量センサに関わる故障診断を行う診断手段と、を備える。【選択図】図6
