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
