Abstract: An information providing system includes a plurality of vehicles, and a server configured to communicate with the plurality of vehicles. A vehicle-side controller of each of a plurality of first vehicles of the plurality of vehicles determines whether or not an act detected by an act detector is an abnormal act that meets a predetermined condition, and, when the vehicle-side controller determines that the act is the abnormal act, the vehicle-side controller transmits, to the server, abnormal act occurrence information including a position of each first vehicle detected by a position detector. A server-side controller collects the occurrence information transmitted from the first vehicles as collected information, and transmits the collected information to a second vehicle of the plurality of vehicles to notify a user of the second vehicle of the collected information.

Abstract: A controller of a first vehicle specifies a position of an unoccupied parking space, from a detected position of the first vehicle and an image shot with a camera. A server-side controller transmits target parking space information indicating a position of a parking space within a predetermined range from a position of a second vehicle which has transmitted a request, of the positions of the parking spaces indicated by vacant parking space information from the first vehicle, to the second vehicle. A controller of the second vehicle obtains the target parking space information from the server. An informer of the second vehicle informs the position of the parking space indicated by the obtained target parking space information.

Abstract: A traffic light information providing system includes a vehicle and a server configured to communicate with the vehicle, and provides information on change in color of a traffic light to the vehicle. The vehicle transmits to the server, vehicle data including time information and position information of the vehicle at the time when the vehicle resumes running from a state of stop at an intersection. The server operates and stores a period of change from the red light to the green light of a traffic light provided at the intersection based on the vehicle data. The server transmits information indicating timing of change to the green light of the traffic light based on the stored period of change, to a vehicle which approaches the intersection.

The server includes: a provision DB configured to store one or more pieces of association information in which respective pieces of location information are associated with respective acceptance periods; a determination device configured to determine a power supply facility corresponding to the desired location and the desired starting time; and a communicator configured to notify a location of the power supply facility.

Abstract: A vehicle management system includes a vehicle controller mountable in a vehicle, and a commercial facility management system for managing a parking lot and payment in a commercial facility. The commercial facility management system includes a system controller. The system controller performs processing for associating the vehicle with a user of the vehicle when the vehicle enters the parking lot, and cooperates with the vehicle controller of the vehicle associated with the user to control the vehicle to travel from a parking place to a pick-up/drop-off place for the user when the user finishes payment.

Abstract: A vehicle search system includes a vehicle incorporating a vehicle-mounted camera and a server configured to communicate with the vehicle. The server transmits search target vehicle data for specifying a search target vehicle to the vehicle. The vehicle is configured to (a) store the search target vehicle data from the server and (b) transmit, when a vehicle detected by the vehicle-mounted camera falls under search target vehicles included in the search target vehicle data, detection information on the detected vehicle to the server.

Abstract: The electric rotating machine includes a rotor relatable around a rotating shaft disposed horizontally, a stator core formed with slots, and a stator coil constituted of in-slot portions each of which is accommodated in a corresponding one of the slots, and turn portions each of which connects corresponding adjacent two of the in-slot portions at a position outside the stator core. The turn portions form a coil end projecting axially outward from an end surface of the stator core at each of both axial end sides of the stator core. The coil end is formed in a cylindrical shape including an axial end surface of a flat shape, and inner and outer peripheral surfaces of a circular shape. The electric rotating machine further includes a coolant supply section to supply coolant to an upper part of the outer peripheral surface of the coil end.

Abstract: A rotating electric machine includes a stator and a rotor. The tip of a salient pole portion of the rotor is bilaterally asymmetrically provided with a cut. The effect of the cut reduces torque ripple during a regenerative running mode. The regenerative running mode is not performed during low speed running but is often performed during high speed running and the driver is more sensitive to in the regenerative running mode noise than in a power running mode. As for the regenerative running mode, measures against torque ripple are taken based on the structure of the rotating electric machine. Preferably, as for the power running mode which bothers the driver about noise during very low speed running, a controller allows a compensation current to be fed to take measures against torque ripple. A compact and high power vehicle drive system with torque ripple reduced and a vehicle incorporating the vehicle drive system can be provided.

Abstract: There are provided a rotor of a rotating electric machine that can implement high-speed rotations with improved energy efficiency, as well as the rotating electric machine and a vehicle drive apparatus. The rotor of the rotating electric machine includes two magnets arranged within an electrical angle in the range of 127° to 140°, the electrical angle having its center at the center of rotations of the rotor, and the magnets being arranged along a V-shape with its acute end facing toward the center of rotations. The rotor further includes a rotor body having two openings housing the two magnets respectively. The rotor body has a support portion placed at the acute end of the V-shape and serving as a partition between the two openings.

Abstract: A rotor is provided with slits each of which serves as a flux barrier blocking a magnetic flux. A direction shown by an arrow is a forward direction along which the rotor rotates when a vehicle moves forward. Each of the slits has a width tapering down from a trailing position toward a leading position with respect to the forward direction. The rotation in a reverse direction opposite to the forward direction shown by the arrow causes larger magnetic flux linkage than the rotation in the forward direction, and hence generates high torque and high counterelectromotive force. Therefore, in the reverse direction, the rotor cannot serve as a motor to produce an output unless high voltage is applied thereto. Accordingly, the torque generated in the reverse direction is used for regenerative operation. It is thereby possible to provide a vehicle drive system capable of exhibiting performance in a well-balanced manner between power running and regenerative operation, and a vehicle provided with the same.
