ABSTRACT:
When an automatic parking control operation is carried out, while allowing a vehicle to creep at a low speed, a net braking force applied to the vehicle is appropriately estimated. That is, not only a braking force generated by operation of a brake pedal but also a braking force generated due to an inclination or unevenness of a road surface or the like are taken into consideration. When the vehicle speed is, for example, in a range of 3 km/hr to 10 km/hr, it is determined that a suitable braking force has been generated for carrying out the automatic parking control operation. To bring the vehicle speed into the predetermined range, it is necessary a) to generate a braking force by operation of the brake pedal on a flat road, b) to generate a negative braking force (a driving force) by operation of an accelerator pedal on a steep ascending slope and c) to generate a larger braking force by operation of the brake pedal on a descending slope.
