In a parking assistance system comprising: a power transmission device provided on a ground side and configured to transmit power; and a power receiving device provided in a vehicle and configured to receive the power transmitted by the power transmission device and supply the power to an electric load, the power transmission device includes: a power transmission coil configured to transmit the power; imaging means for imaging the power transmission coil; and sending means for sending the power receiving device an image captured by the imaging means, and the power receiving device includes: a power receiving coil configured to receive the power transmitted by the power transmission coil; receiving means for receiving the image; and display control means for displaying the image received by the receiving means on display means.

Parking assistance system and parking assistance device

A parking assistance method provides parking assistance when parking a vehicle in a parking space equipped with a ground coil for supplying electric power via a wireless connection to a vehicle coil mounted on the vehicle, at least two ground marks indicating a position of the ground coil, and a parking frame. The parking assistance method switches from a bird's-eye image including the vehicle and a circumference of the vehicle as viewed from above the vehicle to an enlarged image showing a relative position between the ground coil and the vehicle coil on a larger scale than the bird's-eye image when an absolute value of a relative angle between a longitudinal direction of the parking frame and a front-rear direction of the vehicle is a predetermined value or smaller.

Parking assistance method and parking assistance device

A wireless power supply device includes a marker provided closer to a side where a vehicle enters when parked than a power transmission coil unit housing a power transmission coil. The marker includes at least two segments not parallel to each other, and an end portion of one segment is connected to another segment. The power transmission coil is separated by a predetermined distance from a point of intersection of the two segments in a direction in which the one segment extends.

Parking assist device

A parking assistance device includes: imaging means mounted on a vehicle to image a periphery of the vehicle; a coil for a vehicle installed on a bottom surface of the vehicle; a displaying means that displays an image; and a controlling means that performs a display control on the displaying means. The controlling means stores a parking initial image, simultaneously showing a power transmission coil installed on a road surface in a parking space and ground marks provided at a predetermined distance from the power transmission coil, displays the power transmission coil on the displaying means with reference to the ground marks imaged by the imaging means and the parking initial image when a distance between the vehicle and a target parking position falls below a predetermined value, and superposes and displays an image indicating the coil for a vehicle on the displaying means.

Parking assistance device and parking assistance method

In a parking assistance device, a ground mark indicating the coil axis direction and position of a ground coil is placed at a parking space, and a vehicle mark indicating the coil axis direction and position of a vehicle coil is displayed in an image displayed on a display unit. Then, the vehicle mark is displayed in the image in such a way as to be superimposed on the ground mark when the vehicle on which the vehicle coil is mounted reaches a position and angle at which the vehicle can be wirelessly charged.
