To highly accurately detect that a human hand contacts with or approaches a rim, without being affected by an electrostatic capacitance of a heater and heat from the heater.SOLUTION: A sensor device detects that a hand of a driver contacts with or approaches a steering device operated in a state where the driver grips it. The steering device has a heater for heating the steering device and a gripping part that is a part where the driver grips, the sensor device including an electrode that is provided in a part different from the heater of the steering device and can be capacitively coupled to the hand of the driver to be detected, and a control part which is electrically connected to the electrode and detects the change in the electrostatic capacitance of the electrode generated when the hand of the driver contacts with or approaches the gripping part, and determines whether or not the hand of the driver contacts with or approaches the gripping part on the basis of the change in the electrostatic capacitance.SELECTED DRAWING: Figure 1

    【課題】ヒータの静電容量の影響、およびヒータからの熱の影響を受けることなく、人の手がリムに接触または近接したことを高い精度で検出できるようにすること。【解決手段】運転者が握った状態で操作するステアリング装置への運転者の手の接触または近接を検出するセンサ装置であって、ステアリング装置は、ステアリング装置を加熱し温めるヒータと運転者が握る部分である把持部とを有し、センサ装置は、ステアリング装置のヒータとは異なる部分に設けられた、検出するべき運転者の手と容量結合が可能な電極と、電極と電気的に接続され、把持部に運転者の手が接触または近接した際に発生する電極の静電容量の変化を検出する制御部とを含み、静電容量の変化に基づいて運転者の手が把持部に接触または近接したか否かについて判断する。【選択図】図1
