VEHICLE GUIDANCE APPARATUS AND VEHICLE GUIDANCE METHOD
First Claim
1. A vehicle guidance apparatus to be mounted on an electric vehicle that receives supply power by a power receiving unit in the vehicle in a non-contact manner, charges a power storage device mounted in the vehicle by the received power, and is driven at least by the power stored in the power storage device, the supply power being supplied from a power supplying unit on the ground side, the vehicle guidance apparatus for guiding the electric vehicle so that a relative position between the power receiving unit and the power supplying unit is in a predetermined range,the vehicle guidance apparatus comprising:
- a power supplying parameter acquisition unit configured to acquire a power supplying parameter in the vehicle, the power supplying parameter corresponding to a specification of the power supplying unit;
a power receiving parameter storage unit configured to store a power receiving parameter corresponding to a specification of the power receiving unit;
a charge efficiency calculation unit configured to calculate a charge efficiency according to the relative position between the power supplying unit and the power receiving unit based on the power supplying parameter and the power receiving parameter; and
a display processing unit configured to display a range of the charge efficiency with respect to a center of the power receiving unit on a display unit.

Abstract
A vehicle guidance apparatus includes a power supplying parameter acquisition device, a power receiving parameter storage device, a charge efficiency calculator, and a display processing device. The power supplying parameter acquisition device is configured to acquire in a electric vehicle a power supplying parameter which corresponds to a specification of a power supplier. The power receiving parameter storage device is configured to store a power receiving parameter corresponding to a specification of a power receiver. The charge efficiency calculator is configured to calculate a charge efficiency according to a relative position between the power supplier and the power receiver based on the power supplying parameter and the power receiving parameter. The display processing device is configured to display on a display a range of the charge efficiency with respect to a center of the power receiver to guide the electric vehicle.
