A power-receiving device includes a secondary-side coil which can receive a first alternating current power without contact from a power-sending device having a primary side coil into which first alternating current power is input. The power-receiving device comprises a first power transmission path, a second power transmission path, a common path positioned in common with the first and second power transmission paths, and a voltage regulator arranged on the common path. The voltage regulator rectifies the first alternating current power received by the secondary coil or the second alternating current power from a connecting portion, converts the rectified power to a predetermined specific voltage value, and outputs the power.

A contactless power transmission device includes a switching unit that switches a power transmission line so that a first power is transmitted through the first line when an AC power supply outputs a first AC power and so that a second power is transmitted through a second line when the AC power supply outputs a second AC power. An impedance conversion unit is arranged on the second line that converts an impedance from an output of the AC power supply to a variable load when the second power is transmitted through the second line to approach an impedance from the output of the AC power supply to the variable load when the first power is transmitted through the first line.

A parking assistance apparatus makes it easy for a driver to grasp a relative positional relation between a vehicle and a target parking position and makes it possible to park the vehicle at the target parking position in a parking space with accuracy. An image of a mark M in a parking space S is taken by a vehicle-side camera. A relative position calculation portioncalculates a relative positional relation between the vehicle and a target parking position T based on the taken image of the mark M. A backward locus calculation portioncalculates an expected locus when the vehicle moves based on the relative positional relation and based on a steering angle detected by a steering angle sensor. An image of the parking space S is taken by a parking-space-side cameraand transmitted to a vehicle-side apparatus. An image composition portioncomposes the image of the parking space S from the parking-space-side cameraand the expected locus calculated by the backward locus calculation portion. The composed image is displayed on the monitorlocated in the vicinity of a drivers seat of the vehicle.
