Parking Assistance System

摘要

A parking assistance system includes: a light source provided at a parking position at which a power transmission coil is provided, and configured to emit light; at least two light reception units mounted away from each other on a vehicle including a power reception coil, and each configured to receive the light emitted from the light source by using a position sensitive detector; an incident-angle calculation unit configured to calculate the incident angle of the light on each of the light reception units; a distance calculation unit configured to calculate the distance between the parking position and the vehicle from the incident angles of the light on the light reception units; and a detection unit configured to detect that the vehicle has approached the parking position. The light volume of the light source is reduced when the vehicle has approached the parking position.
