ABSTRACT:
An apparatus for preventing a vehicle from deviating from the correct locus of movement thereof when the vehicle travels in a direction opposite to the direction designated by a gear selecting lever during an automatic parking control operation. When automatic parking control operation is started, the wheels are automatically steered on the basis of the relation between the traveling distance of the vehicle and a standard steering angle which is stored in advance in a storage device, and the vehicle is guided automatically to a parking position. When the vehicle, for which the automatic parking control operation has been started from a position O, moves back from a position Q due to the inclination of the road surface, the automatic parking control operation necessarily continues to be carried out unless the forward movement or backward movement of the vehicle is recognized and the vehicle travels to a different position O'. When the forward or backward movements of the vehicle is recognized, and when the vehicle moves back from the position Q, the standard steering angle .theta.ref is reproduced reversely from the position Q and outputted, whereby the vehicle can be returned to the original position O.
