An initial value θ0 of a vehicle deflection angle θ and an initial value L0 of a distance L are set, a normalized coefficient R is determined from the ratio of the vehicle deflection angle θ or the distance L to the initial value θ0 or the initial value L0 when vehicle stop control is started, and the target speed VREF of a body speed VL is determined by that coefficient R. Since the body speed V of the vehicle VL is very low when the vehicle VL arrives at a target parking position, the vehicle VL can be stopped precisely at the target parking position.
