To reduce an uncomfortable feeling of a driver while ensuring an assisting effect in assisting to steer a motor vehicle.SOLUTION: A steering assist device includes: a target steering angle deriving unit that derives a target steering angle corresponding to a situation related to traveling of an own vehicle, such as a target track of the own vehicle; a steering assist torque calculating unit that calculates a steering assist torque having a magnitude corresponding to a difference between a steering angle of the own vehicle and the target steering angle; and a target steering angle correcting unit that, based on at least one of a physical quantity of the difference between the steering angle of the own vehicle and the target steering angle and a physical quantity of the steering assist torque, instructs the target steering angle deriving unit to correct the target steering angle so that the target steering angle is smaller than an angle corresponding to the difference between the steering angle of the own vehicle and the target steering angle.SELECTED DRAWING: Figure 2
【課題】自動車の操舵支援において、支援効果を確保しつつ、ドライバの違和感を低減する。【解決手段】操舵支援装置は、自車両の目標軌道等の自車両の走行に関係する状況に応じた目標操舵角を導出する目標操舵角導出部と、前記自車両の操舵角と前記目標操舵角との差に応じた大きさの操舵支援トルクを算出する操舵支援トルク算出部と、前記自車両の操舵角と前記目標操舵角との差、及び前記操舵支援トルクの少なくとも一方の物理量に基づいて、前記目標操舵角が前記自車両の操舵角と前記目標操舵角との差に対応する角度より小さい角度になるように前記目標操舵角導出部に対して前記目標操舵角の修正の指示を行う目標操舵角修正部と、を含む。【選択図】図2
