Abstract

An information exchange system is capable of realizing useful information exchange both for the service provider located along the road and providing services and the vehicular driver, by effectively using limited communication capacity of the road-vehicle radio communication. The information exchange system has a vehicle-mounted unit and a road-side unit providing information to the vehicle-mounted unit using a road-vehicle radio communication. The vehicle-mounted unit includes receiving unit receiving information transmitted from the road-side unit through a radio communication and transferring unit transferring at least a part of a content of the received information to a vehicular occupant. The road-side unit including storage unit storing information to be transmitted to the vehicle-mounted unit and transmitting unit transmitting information to the vehicle-mounted unit through the radio communication. The storage means stores at least information relating to a service provider where a service is provided at the location thereof. The road-side unit also includes editing unit editing information stored in the storage means on the basis of a relative position between the service provider and a communication region of the transmitting means and generating an edited information to be transmitted from the transmitting means.

Claims

1. An information exchange system comprising:

a vehicle-mounted unit mounted on a vehicle;

a road-side unit providing information to said vehicle-mounted unit using a road-vehicle radio communication;

said vehicle-mounted unit including means for receiving information transmitted from said road-side unit and means for transmitting information relating to a kind of the vehicle through the road-vehicle radio communication to said road-side unit;

said road-side unit including means for storing information to be transmitted to said vehicle-mounted unit and means for transmitting and receiving information to and from said vehicle-mounted unit through the road-vehicle radio communication;

said storage means of said road-side unit storing at least information relating to service providers of which services are available when the vehicle moves to the locations thereof; and

said road-side unit further including means for editing information relating to the service providers stored in said storage means on the basis of the information relating to kind of the vehicle received from the transmitting means of said vehicle mounted unit and generating edited information relating to the service providers to be transmitted to the vehicle mounted unit concerned from said transmitting means of said road-side unit, said edited information arranged in an order of priority relating to service providers, and varying depending on the on the kind of vehicle.

2. An information exchange system according to claim 1, wherein the edited information relating to service providers is a list of service providers arranged in a priority order.

3. An information exchange system comprising:

a vehicle-mounted unit mounted on a vehicle;

a road-side unit providing information to said vehicle-mounted unit using a road-vehicle radio communication;

said vehicle-mounted unit including means for receiving information transmitted from said road-side unit and means for transmitting information relating to destination of the vehicle through the road-vehicle radio communication to said road-side unit;

said road-side unit including means for storing information to be transmitted to said vehicle-mounted unit and means for transmitting and receiving information to and from said vehicle-mounted unit through the road-vehicle radio communication;

storage means of said road-side unit storing at least information relating to service providers of which services are available when the vehicle moves to the locations thereof; and

said road-side unit further including editing means for editing information relating to the service providers stored in said storage means on the basis of the information relating to a destination of the vehicle received from the transmitting means of said vehicle mounted unit and generating edited information relating to the service providers to be transmitted to the vehicle mounted unit concerned from said transmitting means of said roadside unit said edited information arranged in an order of priority relating to service providers, and varying depending on the destination of the vehicle.

4. An information exchange system according to claim 3, wherein the edited information relating to service providers is a list of service providers arranged in a priority order.

5. An information exchange system comprising:

a vehicle-mounted unit mounted on a vehicle;

a road-side unit providing information to said vehicle-mounted unit using a road-vehicle radio communication;

said vehicle-mounted unit including receiver and a transmitter to transmit information relating to a kind of the vehicle through the road-vehicle radio communication to said road-side unit;

said road-side unit including storage to store information to be transmitted to said vehicle-mounted unit and a transmitter and a receiver;

said storage storing at least information relating to service providers of which services are available when the vehicle moves to the locations thereof; and

said road-side unit further including an editor to edit information relating to the service providers stored in said storage on the basis of the information relating to kind of the vehicle received from the transmitter of said vehicle mounted unit and generating edited information relating to the service providers to be transmitted to the vehicle mounted unit concerned from said transmitting means of said road-side unit, said edited information arranged in an order of priority relating to service providers, and varying depending on the on the kind of vehicle.

6. An information exchange system according to claim 5, wherein the edited information relating to service providers is a list of service providers arranged in a priority order.

7. An information exchange system comprising:

a vehicle-mounted unit mounted on a vehicle;

a road-side unit providing information to said vehicle-mounted unit using a road-vehicle radio communication;

said vehicle-mounted unit including receiver and a transmitter to transmit information relating to destination of the vehicle through the road-vehicle radio communication to said road-side unit;

said road-side unit including storage to store information to be transmitted to said vehicle-mounted unit and a transmitter and a receiver;

said storage storing at least information relating to service providers of which services are available when the vehicle moves to the locations thereof; and

said road-side unit further including an editor to edit information relating to the service providers stored in said storage on the basis of the information relating to the destination of the vehicle received from the transmitter of said vehicle mounted unit and generating edited information relating to the service providers to be transmitted to the vehicle mounted unit concerned from said transmitting means of said road-side unit said edited information arranged in an order of priority relating to service providers, and varying depending on the destination of the vehicle.

8. An information exchange system according to claim 8, wherein the edited information relating to service providers is a list of service providers arranged in a priority order.
