Patent ID: 6845362

Claim:
A charging system comprising: a GPS positioning device for detecting a position of a moving body; a monitor device which, by using the GPS positioning device, generates information expressing a ground position of the moving body; and a charging processing device which, by using the information generated by the monitoring device, judges whether or not the ground position is within a charge region, and if the charging processing device judges that the ground position is within a charge region, the charging processing device carries out data processing for charging the moving body, wherein the monitor device has simple data including at least absolute positions and configurations of facilities or geographical features which make it impossible to receive a GPS positioning signal, and when it is impossible to receive the GPS positioning signal, by the information generated by the monitoring device which was generated before it became impossible to receive the GPS positioning signal, the monitor device detects, from the simple data, a facility or geographical feature which made it impossible to receive the GPS positioning signal at a current time, and changes the detected absolute position of the facility or the geographical feature to the information generated by the monitoring device and makes the information generated by the monitoring device be the current ground position of the moving body and the information includes data expressing positions of both ends of a radio wave blocked interval of a facility or a geographical feature.
