PROBLEM TO BE SOLVED: To effectively support a driving operation of a driver for parking without requiring a sensor with high accuracy. SOLUTION: Because a steering wheel Wf is automatically steered based on a preliminarily stored advancing moving locus while a vehicle V moves forward from a parking starting position P1 up to an advancing direction switching position P2, the vehicle V can be rightly stopped at the advancing direction switching position P2. Therefore, only if a driver holds a steering angle θ max at the advancing direction switching position P2 while the vehicle V moves backward from the advancing direction switching position P2 to a parking termination position P3, the vehicle V can be rightly guided to the parking termination position P3. Because the driver can perform a fine adjustment for an advancing direction by operating a steering wheel while the vehicle V moves backward, even if a slight error exists at a stop position of the vehicle V at the advancing direction switching position P2, a highly accurate sensor is not required to be used as each kind of sensor for performing the automatic steering and it can be contributed to reduction of cost. |
