Abstract

A charging support device is used in charging a battery of a vehicle having a power reception unit on a bottom surface of the vehicle with power supplied from a power transmission device located outside the vehicle. The charging support device includes a controller that generates an overhead view image that displays a vehicle image of the vehicle and an image of a surrounding area of the vehicle captured by a camera. The controller displays, in the overhead view image, (i) a first mark indicating a position of the power reception unit and (ii) a second mark indicating a position of the power transmission device. The controller varies a color or a size of the second mark in a case where a positional relationship between the position of the power reception unit and the position of the power transmission device achieves a predetermined charging efficiency.

Claims9

Dependent claims

A charging support device comprising:

a controller that (A) acquires (i) an image which is captured by an imaging unit which captures a surrounding area of a vehicle so as to include a power transmission device which supplies a power to the vehicle in a non-contact manner, and (ii) a movement direction and a movement distance of the vehicle, (B) detects a position of the power transmission device based on the image, the movement direction, and the movement distance, (C) calculates a charging efficiency based on a distance between (1) a position of a power reception unit which is included in the vehicle and that is configured to receive the power from the power transmission device and (2) the position of the power transmission device, and (D) outputs a notification based on the calculated charging efficiency to an output unit,
wherein the notification includes changing a color or a size of an image of the power transmission device that is displayed as part of an overhead view image in which the image of the power transmission device is overlaid with an image of the vehicle, based on the charging efficiency.
