PROBLEM TO BE SOLVED: To start immediately speed control for automatic parking regardless of braking-force releasing speed.SOLUTION: After a vehicle 15 is stopped at a position Q near a target parking position O, a torque variation calculation portion 50 calculates torque variations Tsum in relation to reference torque which is generated when the vehicle 15 is travelling on a flat road at predetermined speed V0, on the basis of change in vehicle speed V and an engine condition of the vehicle 15 and brake strokes Bs. Subsequently, a required braking-force calculation portion 70 calculates, on the basis of the calculated torque variations Tsum, braking force F required to be applied to the vehicle 15 in order to achieve the predetermined vehicle speed V0 when making the vehicle 15 automatically travels toward the target parking position O. An automatic parking execution portion 80 allows the vehicle 15 to automatically travel at the predetermined vehicle speed V0 by applying the calculated braking force F to the vehicle 15.SELECTED DRAWING: Figure 1 【課題】自動駐車のための速度制御を、制動力の解除速度に関係なく即座に開始する。【解決手段】車両１５を目標駐車位置Ｏの近傍位置Ｑに停止させて、トルク変動量算出部５０が車両１５の車速Ｖの変化とエンジンの状態、およびブレーキストローク量Ｂｓに基づいて、車両１５が平担路を所定車速Ｖ０で走行しているときに発生する基準トルクに対するトルク変動量Ｔｓｕｍを算出する。次に、必要制駆動力算出部７０が、算出されたトルク変動量Ｔｓｕｍに基づいて、車両１５を目標駐車位置Ｏに向けて自動走行させた際に、所定車速Ｖ０を得るために、車両１５に加える必要がある制駆動力Ｆを算出する。そして、自動駐車実行部８０が、算出された制駆動力Ｆを車両１５に加えることによって、車両１５を所定車速Ｖ０で自動走行させる。【選択図】図１
