Non-contact power receiving apparatus, non-contact power transmitting apparatus, and non-contact power transmitting and receiving system
First Claim
1. A non-contact power receiving apparatus comprising:
- a power reception unit that receives electric power in a non-contact manner transmitted from a power transmitting apparatus external to a vehicle;
a control device that controls the transmitted power from the power transmitting apparatus, the control device controlling the transmitted power based on (i) a monitoring result obtained by monitoring surroundings of the vehicle, and (ii) an occupant detection result obtained by detecting whether or not an occupant enters the vehicle;
a monitoring unit that monitors a monitored region around the vehicle and outputs the monitoring result to the control device; and
a vehicle entry detection unit that detects whether or not the occupant enters the vehicle, whereinafter an approach of a moving object to the vehicle is detected based on an output from the monitoring unit, when it is detected that the moving object has moved to a non-monitored region, the control device detects whether or not the occupant enters the vehicle with the vehicle entry detection unit.

Abstract
A non-contact power receiving apparatus includes a power reception unit for receiving electric power in a non-contact manner from a power transmitting apparatus external to a vehicle, and a control device for controlling the transmitted power from the power transmitting apparatus. The control device controls the transmitted power based on a monitoring result obtained by monitoring the surroundings of the vehicle, and an occupant detection result obtained by detecting whether or not an occupant enters the vehicle. When the monitoring result indicates the approach of a moving object to the vehicle, the control device causes the power transmitting apparatus to reduce the transmitted power. The power transmitting apparatus and the power reception unit transmit and receive electric power in a non-contact manner by electromagnetic field resonance.
