PARKING ASSISTANCE APPARATUS
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. Next, in processing S403, 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 S404 where vehicle speed control or the like is performed for the automatic parking in accordance with the malfunction of the external recognition device.

AUTONOMOUS VEHICLE FLEET MANAGEMENT FOR REDUCED TRAFFIC CONGESTION
Techniques are provided for autonomous vehicle fleet management for reduced traffic congestion. A request is received for a vehicular ride. The request includes an initial spatiotemporal location and a destination spatiotemporal location. A processor is used to generate a representation of lane segments. Each lane segment is weighted in accordance with a number of other vehicles on the lane segment. A vehicle located within a threshold distance to the initial spatiotemporal location is identified such that the identified vehicle has at least one vacant seat.
