Abstract

The present invention relates to an apparatus and method for a vehicle navigation service using a DSRC(Dedicate Short Range Communication) capable of providing a traffic information to which a current traffic state is adapted to a vehicle driver, so that the vehicle driver is notified of an optimum way, not a traffic congestion way, among the ways formed from the current location to a destination. Therefore, it is possible to prevent a traffic load of the traffic congestion region by avoiding the traffic congestion regions and distribute the traffic loads of the vehicles.

Claims

1. In a vehicle navigation service apparatus using a DSRC(Dedicate Short Range Communication) system, a vehicle navigation service apparatus using a DSRC, comprising:

a traffic information service unit for generating a traffic information in real time;

a road side unit for gathering a vehicle information and a road side information needed for generating traffic information;

a remote access controller for receiving a traffic information from the traffic information service unit, transferring the received information to the road side unit, receiving a vehicle information and road side information from the road side unit and transferring to the traffic information service unit; and

a terminal unit for generating a vehicle information and displaying the traffic information and a location information of the road side unit.

2. The apparatus of claim 1, wherein said road side unit includes a road side equipment(RSE).

3. The apparatus of claim 1, wherein said remote access controller includes:

a data communication network for receiving and outputting a traffic information from the traffic information service unit and transferring the vehicle information and the road side information to the traffic information service unit; and

a remote access means for receiving a traffic information from the data communication network, transferring the received information to the road side unit, receiving a vehicle information and road side information from the road side unit and transferring the received information to the data communication network.

4. The apparatus of claim 1, wherein said terminal unit includes:

an on-board means for forming a DSRC(Dedicate Short Range Communication) region and generating a vehicle information; and

a terminal apparatus for generating a map data, displaying the current location and the traffic information and performing a way guide function.

5. The apparatus of claim 4, wherein said on-board means is an on-board equipment(OBE).

6. In a vehicle navigation service method using a DSRC(Dedicate Short Range Communication) apparatus, a vehicle navigation service method using a DSRC apparatus, comprising:

a first step having;

a first sub-step for transferring a traffic information generated by a traffic information service unit to a road side unit through a remote access controller;

a second sub-step in which the road side unit which received the traffic information from the traffic information service unit transfers a traffic information and a location information to a terminal unit having an on-board means; and

a third sub-step for displaying the current location and an optimum way of a vehicle in the terminal unit which receives the traffic information and location information by the road side unit; and

a second step having;

a fourth sub-step in which the terminal unit transfers a vehicle information to the road side unit;

a fifth sub-step in which the road side unit which received the vehicle information transfers a road side information needed for generating the traffic information to the traffic information service unit through the remote access controller; and

a sixth step in which the traffic information service unit which received the vehicle information and the road side information gathers a vehicle information and road side information and generates a new traffic information.

7. The method of claim 6, wherein in said sixth sub-step of the second step, a real time traffic information is generated using a road side information transferred from the road side unit when the traffic information is generated.
