Abstract:
Disclosed is a vehicle guidance device that can easily guide a vehicle in the vicinity of a power supply point to the power supply point, even from locations away from the power supply point, by guiding the vehicle along a path of travel to the power supply point without employing image data. In this device, a charging unit (101) receives power from a power supply point (143). A power supply efficiency calculation unit (103) calculates the power supply efficiency, which is the efficiency with which power is received from the power supply point (143) by the charging unit (101). An amount of change calculation unit (105) calculates the amount of change of efficiency of power supply, which is the amount of change of efficiency of power supply calculated by the power supply efficiency calculation unit (103). A vehicle-side control unit (107) displays on a display (108) guidance to enable the vehicle (150) to reach the power supply unit (143), based on the amount of change of efficiency of power supply calculated by the amount of change calculation unit (105).
