On the basis of a parking space (L0) located in front of a vehicle (V) in the direction said vehicle (V) is driving, a drive controller (10) engages an acceleration restriction whereby the acceleration of the vehicle (V) is restricted in accordance with a throttle position. If, with said acceleration restriction engaged, the drive controller (10) detects that the vehicle (V) is stopped, the drive controller (10) gradually disengages the acceleration restriction. If, while the acceleration restriction is being disengaged, the drive controller (10) detects that the vehicle (V) is in motion, the drive controller (10) maintains the acceleration restriction in the state that said acceleration restriction was in when the vehicle (V) was detected as being in motion.
