To provide a steering wheel gripping detection device capable of exactly detecting gripping of a steering wheel even when the vibration of a vehicle itself is large, such as running on a rough road.SOLUTION: A steering wheel gripping detection device 10 includes: an exciter 20 for executing exciting in the rotational direction of a steering wheel 12; a pair of vibration detection sensors 22A and 22B provided symmetrically with regard to a rotating shaft of the steering wheel 12 and detecting vibration of the steering wheel 12; and a control section 24 for determining gripping of the steering wheel 12 by an occupant, using a difference between detection results of the pair of vibration detection sensors 22A and 22B, obtained when the steering wheel 12 is excited by the exciter 20.SELECTED DRAWING: Figure 1

    【課題】悪路走行などのように車両自身の振動が大きい状況でも正確に把持検出可能なステアリング把持検出装置を提供することを目的とする。【解決手段】ステアリング把持検出装置10は、ステアリングホイール12の回転方向に加振する加振器20と、ステアリングホイール12の回転軸に対して対称に設けられ、ステアリングホイール12の振動を検出する一対の振動検知センサ22A、22Bと、加振器20によってステアリングホイール12を加振した場合の一対の振動検知センサ22A、22Bの検出結果の差分を用いて、乗員によるステアリングホイール12の把持を判定する制御部24と、を含む。【選択図】図1
