Method for controlling non-contact electric power supply system, and non-contact electric power supply system

A non-contact electric power supply system in which an electric power receiving coil mounted on a host vehicle is to be opposed to an electric power transmitting coil set on a ground, and electric power is to be supplied from the electric power transmitting coil to the electric power receiving coil in a non-contact manner, the non-contact electric power supply system comprising:

• distance sensors that detect whether another vehicle is parked adjacent to the host vehicle;
• a moving object sensor that detects whether a moving object is present around the host vehicle;
• and
• an electric-power-supply control circuit that stops or reduces the electric power supply when a moving object is detected by the moving object sensor, wherein
• when it is detected that the another vehicle is parked, a detection region of the moving object sensor is expanded as compared to when it is not detected that the another vehicle is parked,
• a distance to the another vehicle is detected by using the distance sensors that are respectively provided on a side in a front and a side in a rear of the host vehicle, and
• the detection region is set according to the distance to the another vehicle detected by the respective distance sensors.
