PROBLEM TO BE SOLVED: To immediately initiate speed control for autonomous parking without a time delay.SOLUTION: When a vehicle 15 is halted at a position near a target parking position, a torque variation quantity calculation unit 50 detects on the basis of deceleration of the vehicle 15, a torque variation quantity with respect to a reference torque which occurs when a vehicle 15 is traveling on a flat road in a creeping state. A necessary braking force calculation unit 70 calculates a braking force which should be applied to the vehicle 15 in order to attain a predetermined vehicle speed that is a vehicle speed, at which the vehicle 15 travels on the flat road in the creep state, when the vehicle 15 autonomously travels toward the target parking position. An autonomous parking execution unit 80 applies the calculated braking force to the vehicle 15, whereby the vehicle 15 autonomously travels to the target parking position at the predetermined vehicle speed.SELECTED DRAWING: Figure 1

    【課題】自動駐車のための速度制御を、時間遅れなく即座に開始する。【解決手段】車両15を目標駐車位置の近傍位置に停止させたときに、トルク変動量算出部50が、車両15の減速度に基づいて、車両15が平坦路をクリープ状態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を検出して、必要制動力算出部70が、トルク変動量に基づいて、車両15を目標駐車位置に向けて自動走行させた際に、車両15が平坦路をクリープ状態で走行しているときの車速である所定車速を得るために、車両15に加える必要がある制動力を算出して、算出された制動力を、自動駐車実行部80が車両15に加えることによって、車両15を所定車速で目標駐車位置まで自動走行させる。【選択図】図1
