To operate a steering input device at a transfer ratio corresponding to a body posture of a driver.SOLUTION: A steering assist device 10 for a vehicle 500 is provided to include a steering input device 41 and a wheel turning device 42. The steering input device is configured to operate at a transfer ratio which is a ratio of change of a wheel turning angle to a change of a steering angle. The steering assist device 10 includes a wheel turning device drive part 32 configured to drive the wheel turning device 42, a body posture detection part 23 configured to detect a body posture of a driver of the vehicle, a steering control part P1, 101 configured to determine a wheel turning angle on the basis of at least one of a traveling state and a traveling road information of the vehicle 500 and to execute an automatic steering mode in which the wheel turning device drive part 32 is controlled to realize the determined wheel turning angle, and a transfer ratio setting part P2, 101 configured to set a transfer ratio corresponding to the body posture detected during execution of the automatic steering mode.SELECTED DRAWING: Figure 3

    【課題】運転者の身体姿勢に応じた伝達比にて操舵入力装置を作動させること。【解決手段】操舵角の変化量に対する転舵角の変化量の比である伝達比にて差動する操舵入力装置41および転舵装置42を有する車両500の操舵支援装置10が提供される。操舵支援装置10は、転舵装置42を駆動する転舵装置駆動部32と、車両の運転者の身体姿勢を検出する身体姿勢検出部23と、車両500の走行状態または走路情報の少なくともいずれか一方に基づき転舵角を決定し、決定された転舵角を実現するように転舵装置駆動部32を制御する自動操舵モードを実行する操舵制御部P1、101と、自動操舵モードの実行中に、検出された身体姿勢に応じて伝達比を設定する伝達比設定部P2、101とを備える。【選択図】図3
