To promptly and highly accurately detect a steering wheel hands-off state.SOLUTION: A steering holding state detection device 100 includes: a torque acquisition unit 122 configured to sequentially acquire steering torque applied to a vehicle steering handle; a calculation unit 124 configured to calculate an average value of the steering torque sequentially acquired and a standard deviation of the steering torque; and a state determination unit 126 configured to determine, based on the calculated average value and the calculated standard deviation of the steering torque, whether the steering wheel is in a hands-off state in which the steering wheel is not held while a vehicle is traveling.SELECTED DRAWING: Figure 2
【課題】ハンドルの手放し状態を迅速かつ高精度に検出する。【解決手段】保舵状態検出装置100は、車両のハンドルに加わる操舵トルクを順次取得するトルク取得部122と、順次取得した操舵トルクの平均値と、操舵トルクの標準偏差とを求める算出部124と、求めた操舵トルクの平均値及び標準偏差に基づいて、車両走行中にハンドルが保舵されていない状態を示す手放し状態であるか否かを判定する状態判定部126とを備える。【選択図】図2
