To reduce a sense of discomfort when an own vehicle is decelerated on the basis of a speed profile according to a relative distance between a target position in front and the own vehicle.SOLUTION: A braking-driving force control method includes: calculating a relative distance between a target position in front and an own vehicle (S3); calculating a first target speed on the basis of a first speed profile which is a speed profile showing a vehicle speed according to a distance to the target position, and in which a prescribed set speed is reached before the target position by decelerating at first deceleration (S4); calculating a second target speed on the basis of a second speed profile which is set as a speed profile according to a distance to the target position, and in which the set speed is reached at the target position by decelerating at second deceleration greater than the first deceleration (S5); and correcting braking-driving force according to accelerator operation by subtracting the greater amount of correction with the increase of a ratio obtained by dividing a difference obtained by subtracting the first target speed from a relative speed of the own vehicle with respect to the target position, by a difference obtained by subtracting the first target speed from the second target speed (S7, S8).SELECTED DRAWING: Figure 8

    【課題】前方の目標位置と自車両との相対距離に応じた速度プロファイルに基づき自車両を減速する際の違和感を軽減する。【解決手段】前方の目標位置と自車両との間の相対距離を算出し(S3)、目標位置までの距離に応じた車速を示す速度プロファイルであって第1減速度で減速して目標位置より手前で所定の設定速度に達する第1速度プロファイルに基づいて第1目標速度を算出し(S4)、目標位置までの距離に応じた速度プロファイルとして設定され且つ第1減速度よりも大きな第2減速度で減速して目標位置で設定速度となる第2速度プロファイルに基づいて第2目標速度を算出し(S5)、目標位置に対する自車両の相対速度から第1目標速度を減算した差分を第2目標速度から第1目標速度を減算した差分で除算した割合が大きいほどより大きな補正量で減算して、アクセル操作に応じた制駆動力を補正する(S7、S8)。【選択図】図8
