PROBLEM TO BE SOLVED: To control a return steering angle speed at the time when a vehicle travels in a relaxation section in the latter half of a curve to a preferable return steering angle speed according to the curve.SOLUTION: A steering support device for vehicle is configured to acquire information on the curve in a travel path, identify a section with the fixed curvature of the curve on the basis of the information on the curve, calculate the basic target return steering angle speed at the time when the vehicle travels in a relaxation section in the latter half on the basis of the steering angle at the time when the vehicle travels in the section with the fixed curvature (S10-150), calculate the target return steering angle speed by correcting the basic target return steering angle speed on the basis of the relationship between the actual vehicle speed at the time when the vehicle travels in the section with the fixed curvature and the restricted vehicle speed set for the section with the fixed curvature (S160), and control an electric power steering device so that the return steering angle speed at the time when the vehicle travels in the relaxation section in the latter half becomes the target return steering angle speed (S170-200).SELECTED DRAWING: Figure 2

    【課題】車両がカーブの後半の緩和区間を走行する際における戻し操舵角速度をカーブに応じた好ましい戻し操舵角速度に制御すること。【解決手段】走行路のカーブの情報を取得し、カーブの情報に基づいてカーブの一定の曲率の区間を特定し、車両が一定の曲率の区間を走行する際の操舵角に基づいて車両が後半の緩和区間を走行する際の基本目標戻し操舵角速度を演算し(S10〜150)、車両が一定の曲率の区間を走行する際の実際の車速と車両が一定の曲率の区間について設定された制限車速との関係に基づいて、基本目標戻し操舵角速度を補正することにより目標戻し操舵角速度を演算し(S160)、車両が後半の緩和区間を走行する際の戻し操舵角速度が目標戻し操舵角速度になるように電動パワーステアリング装置を制御する(S170〜200)よう構成された車両用操舵支援装置。【選択図】図2
