PROBLEM TO BE SOLVED: To easily and quickly detect a hand-off state of a steering wheel.SOLUTION: A steerage holding state detection device 100 includes: a detection part 110 for detecting steering torque applied to a steering wheel 10; a filtering part 132 for filtering steering torque whose frequency is larger than a predetermined value among a plurality of steering torque which the detection part 110 has detected within a predetermined time; and a determination part 133 for obtaining a statistical value indicating variation of the torque values of the plurality of steering torque after a filtering by the filtering part 132 and if the statistical value is smaller than a predetermined value, determines that it is in a hand-off state which indicates that the steering wheel 10 is not in a steerage holding state.SELECTED DRAWING: Figure 1
【課題】ハンドルの手放し状態を容易かつ迅速に検出する。【解決手段】保舵状態検出装置100は、ハンドル10に加わる操舵トルクを検出する検出部110と、検出部110が所定時間内に検出した複数の操舵トルクの中から、周波数が所定値よりも大きい操舵トルクを除去する除去部132と、除去部132が除去した後の複数の操舵トルクのトルク値のばらつきを示す統計値を求め、統計値が所定値よりも小さい場合に、ハンドル10が保舵されていない状態を示す手放し状態であると判定する判定部133と、を備える。【選択図】図1
