Mobile radio communication for automatic toll collection system
First Claim
1. A mobile radio communication device for an automatic toll collection system which charges a toll of a mobile body by executing communications with rode-side communication devices at an entrance gate and an exit gate, the device comprising:
- antennas for receiving map data of the toll charge area from the road-side communication device at the entrance gate;
a GPS receiver I/F for receiving present position information of the mobile body;
a processor configured to facilitate storing as travel path data the present position of the vehicle on the map, calculating an accumulated travel distance covering from the entrance of the toll charge area to the present position based on the travel path data, and calculating an actual travel distance of the mobile body In a toll charge area between the entrance gate and the exit gate based on the accumulated travel distance,wherein the antenna are for transmitting the calculated distance of actual travel of the vehicle to the road-side communication device when at the toll charge area, and for receiving a toll charge calculated based on the calculated distance of actual travel from the road-side communication device; and
output means for outputting the toll charge in the vehicle,wherein the processor check whether the mobile body has traveled in a special toll area based on the map data and the present position information when the toll charge area includes a special toll area in which a special toll is charged and charges the special toll when a check result indicates that the mobile body has traveled in the special toll area, andwherein the processor calculates the special toll in correspondence with a distance which the mobile body has traveled in the special toll area.

Abstract
A mobile radio communication device for an automatic toll collection system executes toll charging processing and travel guide. It communicates with road-side communication devices at an entrance gate and an exit gate in a toll charge area to receive map data. It also receives present position information from a GPS receiver circuit. It executes processing necessary for toll charging based on the received map data and present position information. It also provides a travel guide in the toll charge area.

6. A mobile radio communication method for an automatic toll collection system comprising the steps of:
-
receiving map data of a toll charge area from road-side communication devices provided in the toll charge area upon entering and leaving the toll charge area; receiving present position information of a vehicle from a GPS system; executing predetermined processing based on the present position information and the map data, the predetermined processing including storing as travel path data the present position of the vehicle on the map, calculating an accumulated travel distance covering from the entrance of the toll charge area to the present position based on the travel path data, and calculating a distance of actual travel of the vehicle in the toll charge area based on the accumulated travel distance; transmitting the calculated distance of actual travel of the vehicle to the road-side communication device when leaving the toll charge area; calculating a toll charge in the toll charge area based on the calculated distance of actual travel; receiving the calculated toll charge through the road-side, communication device; and outputting the calculated toll charge in the vehicle, wherein the executing further includes; checking whether the vehicle is in a special toll charge area in the toll charge area the special toll charge area being for charging a special toll different from a normal toll in a normal toll charge area of the toll charge area; and calculating the special toll charge and the normal charge separately in correspondence with distance of actual travel of the vehicle in the special toll charge area and the normal charge area respectively. - View Dependent Claims (7, 8, 9, 10, 11)
