CONTACTLESS POWER TRANSFER SYSTEM AND VEHICLE
First Claim
1. A contactless power transfer system, comprising:
- a charging station including a first communication unit and a power transferring unit; and
a vehicle including a second communication unit, a power receiving unit, a display unit and an electronic control unit, the second communication unit being configured to communicate with the first communication unit, the power receiving unit being configured to contactlessly receive electric power from the power transferring unit, the display unit being configured to indicate a relative positional relationship between the power receiving unit and the power transferring unit, and the electronic control unit being configured to control the second communication unit, the power receiving unit and the display unit, whereina vehicle parking region is a region in which the vehicle is positioned in a state where the power receiving unit is disposed so as to face the power transferring unit, the first communication unit is configured to output a first signal so that the first signal reaches the outside of the vehicle parking region and the second communication unit is configured to receive the first signal from the charging station at outside the vehicle parking region, and the electronic control unit is configured to start a display of the positional relationship on the display unit, when the second communication unit receives the first signal, whereina plurality of parking bays are provided in the charging station, and the first communication unit of the charging station is configured to output the first signal when determination is made that another vehicle is not parked over at least one of the power transferring unit.

Abstract
A contactless power transfer system includes a vehicle and a charging station. The charging station includes a first communication unit and a power transferring unit. The vehicle includes a second communication unit configured to communicate with the first communication unit, a power receiving unit configured to contactlessly receive power from the power transferring unit, a display unit for indicating a relative positional relationship between the power receiving unit and the power transferring unit, and a control unit (vehicle ECU) controlling the second communication unit the power receiving unit and the display unit. The vehicle ECU starts display of a relative positional relationship between the power receiving unit and the power transferring unit, on the display unit, when the second communication unit receives a broadcast signal from the first communication unit.
