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 S, a determination is made whether or not an external recognition device, such as a camera or sonar, malfunctions. In processing S, 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. Next, in processing S, a determination is made whether or not the automatic parking is in progress. When the automatic parking is in progress, the process proceeds to processing Swhere vehicle speed control or the like is performed for the automatic parking in accordance with the malfunction of the external recognition device.
