PROBLEM TO BE SOLVED: To make it possible to detect a hand-free state such that steerage of a handle is not held, with high accuracy.SOLUTION: A steerage holding state detection device 1 has: a detection part 11 which detects steering torque which is added to a handle 2; a lead-out part 131 which leads out variation in plural steering torque values which indicate plural steering torque magnitudes which are detected by the detection part 11 within a prescribed period; and a judgement part 132 which judges a hand-free state such that steerage of the handle 2 is not held when variation in the plural steering torque values is smaller than a prescribed value.SELECTED DRAWING: Figure 1
【課題】ハンドルが保舵されていない手放し状態を高い精度で検出する。【解決手段】保舵状態検出装置1は、ハンドル2に加わる操舵トルクを検出する検出部11と、検出部11が所定期間内に検出した複数の操舵トルクの大きさを示す複数の操舵トルク値のばらつきを導出する導出部131と、複数の操舵トルク値のばらつきが所定値より小さい場合に、ハンドル2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132と、を有する。【選択図】図1
