Abstract: When one sensors fails and thus malfunctions during automatic parking of a vehicle, only the other sensor functions. Accordingly, depending on the behavior of the vehicle, the detection characteristics of the other sensor cause degradation in recognition of the vehicle, hindering the automatic parking from being continued. In processing S401, a determination is made whether or not an external recognition device, such as a camera or sonar, malfunctions. In processing S402, based on the determination on malfunction of the external recognition device, a determination is made whether or not to restrict vehicle speed or to restrict a path, with reference to restriction information for parking control. The restriction information for parking control provides information for restricting the vehicle speed in accordance with the malfunction of the camera, and for restricting the path in accordance with the malfunction of the sonar.
