A vehicle includes a power receiving unit and an RFID tag. The power receiving unit contactlessly receives electric power output from a power transmission unit. The RFID tag preliminarily stores information which is identification information for identifying the vehicle in the power transmission device and can be contactlessly read by the power transmission device. Here, the RFID tag is arranged at a vehicle body front end (a vehicle body trailing end) in a vehicle traveling direction when the vehicle is guided into a parking frame.

Vehicle, power transmission device, and power feeding system

In a non-contact electric power feed system, electric power is supplied in a non-contact manner from an electric power transmission device to a vehicle representing an electric power reception device. The electric power transmission device includes an electric power transmission unit, a communication unit for radio communication with the electric power reception device, and a control device for controlling the electric power transmission unit. The control device varies transmitted electric power from the electric power transmission unit while the electric power transmission unit transmits electric power, and determines whether or not pairing between the vehicle specified as an electric power transmission target and the electric power transmission unit is appropriate, based on information on variation in electric power from the vehicle specified as the electric power transmission target through radio communication.

Electric power transmission device, electric power reception device, vehicle, and non-contact electric power feed system

A vehicle is able to contactlessly receive electric power from a power transmitting device and to charge a mounted electrical storage device (electric load). The vehicle includes a communication unit that carries out wireless communication with the power transmitting device and a vehicle ECU (control unit) that controls the communication unit. The communication unit is able to switch a communication range between a wide communication range (wire-area communication) and a narrow communication range (narrow-area communication). The vehicle ECU, at the time of identifying a power transmitting device from which electric power should be received, controls the communication unit such that the communication unit communicates with the power transmitting device using the narrow-area communication.

Vehicle, power receiving device, power transmitting device, and contactless power supply system

A contactless power transfer system supplies power from a power transmitting device to a vehicle in a contactless manner. The power transmitting device and the vehicle are configured to be capable of exchanging information with each other through radio communication. The vehicle is provided with an RFID tag in which information on the vehicle is stored in advance. The power transmitting device includes an RFID reader that reads out information from the ID tag in a contactless manner. A power transmitting ECU recognizes that the vehicle is a vehicle to be supplied with power from the power transmitting device if vehicle information indicated by information from the ID tag corresponds to vehicle information indicated by information received through radio communication.

A viewpoint location computation device that computes a viewpoint location of a driver includes: a first estimated viewpoint location computation unit that computes a first estimated viewpoint location based on the angle of the right side-view mirror and a driver's seating center plane of the vehicle; a second estimated viewpoint computation unit that computes a second estimated viewpoint location based on the angle of the left side-view mirror and the driver's seating center plane of the vehicle; an identical condition determination unit that determines whether the estimated viewpoint locations are identical; and a viewpoint location computation unit that computes the estimated viewpoint location as the viewpoint location of the driver when it is determined that the estimated viewpoint locations are identical, wherein the viewpoint location computation unit computes the viewpoint location based on the estimated viewpoint locations when it is determined that the respective estimated viewpoint locations are not identical.
