To suppress occurrence of a holding/fixing state.SOLUTION: A steering wheel holding determination device is provided with: an electrostatic capacity sensor 11 that can detect, as a detected electrostatic capacity, an electrostatic capacity between an electrode and an object; a steering input value sensor 12 that can detect a steering input value which is an input value based on operation of a steering wheel by a driver in a vehicle; and a control unit 10 that is configured to renew a reference electrostatic capacity by the detected electrostatic capacity every time when a predetermined calculation time elapses and to perform holding-determination of whether the steering wheel is in a holding state where the steering wheel is held by the driver or not, on the basis of a result of whether the detected electrostatic capacity is over a holding determination threshold calculated based on the reference electrostatic capacity or not. The control unit stops renewal of the reference electrostatic capacity when the steering input value is equal to a predetermined steering input threshold or more when the detected electrostatic capacity is detected.SELECTED DRAWING: Figure 3
【課題】 保持固着状態の発生を抑制する。【解決手段】 操舵ハンドル保持判定装置は、電極と対象物との間の静電容量を検出静電容量として検出可能な静電容量センサ11と、車両の運転者による操舵ハンドルの操作に基づく入力値である操舵入力値を検出可能な操舵入力値センサ12と、所定の演算時間が経過する毎に基準静電容量を検出静電容量で更新し、検出静電容量が基準静電容量に基づいて演算される保持判定閾値を超えているか否かに基づいて操舵ハンドルが運転者により保持されている保持状態にあるか否かを判定する保持判定を行うように構成された制御ユニット10と、を備える。制御ユニットは、検出静電容量が検出された場合において操舵入力値が所定の操舵入力閾値以上であるときは基準静電容量の更新を停止する。【選択図】 図3
