Devices, methods, and programs that provide vehicle guidance for power reception
First Claim
1. A power reception guidance device for installation in a vehicle having a power receiving unit, the device providing guidance to a non-contact power supply of a power supply unit installed in a parking area, the device comprising:
- a controller that;
calculates an amount of required power that should be received by the power receiving unit;
calculates an estimated parking time of the vehicle based on an average parking time associated with a type of facility where the parking area is located;
calculates a power receiving efficiency of the power receiving unit at a current parking position of the vehicle in the parking area;
calculates a power receiving amount to be received by the power receiving unit while the vehicle is parked, the power receiving amount being calculated based on the calculated power receiving efficiency and the calculated estimated parking time; and
determines whether the current parking position must be changed based on the calculated power receiving amount and the calculated required power amount; and
an output unit that outputs information based on the determination.

Abstract
Power reception guidance devices, methods, and programs guide a vehicle having a power receiving unit to a non-contact power supply of a power supply unit installed in a parking area. The devices, methods, and programs calculate a power receiving efficiency of the power receiving unit at a current parking position of the vehicle in the parking area, determine whether the current parking position must be changed based on the calculated power receiving efficiency, and output information based on the determination to an output unit.
