Abstract

A system for remotely controlling a vehicle in a service area divided into plural service sectors includes: an infra sensor module installed in each service sector for periodically sensing obstacles and vehicles within the service sector; a vehicle controller mounted in each vehicle for requesting the driving guidance service and automatically controlling the vehicle in accordance with a vehicle control signal; and a local server installed in each service sector for communicating with the vehicle controllers through a driving guidance network based on information on the obstacles and vehicles sensed by the infra sensor module. The system further includes a global server for allocating network resources of the driving guidance network to allow the local server to communicate with the vehicle controllers using the allocated network resources.

Claims

1. A system for remotely controlling a vehicle in a service area divided into plural service sectors, comprising:

an infra sensor module installed in each service sector for periodically sensing obstacles and vehicles within the service sector;

a vehicle controller mounted in each vehicle for requesting the driving guidance service and automatically controlling the vehicle in accordance with a vehicle control signal;

a local server installed in each service sector for communicating with the vehicle controllers through a driving guidance network based on information on the obstacles and vehicles sensed by the infra sensor module; and

a global server for allocating network resources of the driving guidance network to allow the local server to communicate with the vehicle controllers using the allocated network resources.

2. The system of claim 1, wherein the local server includes:

a network interface for communicating with the global server;

a database for storing therein the sensed information on the obstacles and the vehicles, and a list of the vehicles having the vehicle controllers which request the driving guidance service;

a vehicle control signal generation unit for generating a vehicle control signal of the vehicles based on the sensed information on the obstacles and vehicles to provide the vehicle control signal to the vehicle controllers requesting the driving guidance service; and

a second network interface for communicating with the vehicle controllers within the service sector.

3. The system of claim 2, wherein the allocated network resources includes a frequency band through which the local server communicates with the vehicle controllers within the service sector and a communication time interval during which the local server communicates with each of the vehicle controllers requesting the driving guidance service.

4. The system of claim 2, wherein the second network interface receives a request for the driving guidance service from the vehicle controllers and transmits the vehicle control signal to the vehicle controllers.

5. The system of claim 4, wherein the local server broadcasts a checking packet to examine whether there is any vehicle controller to require participating in the driving guidance network to the vehicle controllers within the service sector, and upon receipt of a request packet for a network connection from a vehicle controller, transmitting an inquiry message, inquiring to the global server whether the vehicle controller transmitting the request packet is allowed to participate in the driving guidance network.

6. The system of claim 1, wherein the global server includes:

a network interface for communicating with the local servers; and

a wireless resource allocation unit for allocating a communication time interval and a dedicated frequency band of the network resources of the vehicle driving guidance network a vehicle requesting the driving guidance service to each local server.

7. The system of claim 6, wherein the global server further includes:

a handover management unit for detecting a vehicle moving from a service sector where the vehicle has been served the vehicle guidance service to another service sector and transmitting a handover command to a local server in the another service sector.

8. The system of claim 7, wherein the global server further includes a priority management unit for giving a priority to the vehicles for the driving guidance service.

9. The system of claim 8, wherein the priority is given to the vehicles based on a preceding vehicle in the traveling direction thereof.

10. The system of claim 8, wherein the priority is given to the vehicles based on the order of the request for driving guidance service.

11. The system of claim 1, wherein the infra sensor module includes at least one of an image pickup device, a laser scanner and an ultrasonic sensor and geomagnetic sensor.

12. The system of claim 1, wherein the vehicle controller includes:

a network interface for communicating with the local server; and

a vehicle control unit for making the request for the driving guidance service and controlling the vehicle based on the vehicle control signal.

13. A method for a driving guidance service periodically to remotely control vehicles in a service area divided into plural service sectors, each vehicle having a vehicle controller mounted therein to request for the driving guidance service, comprising:

detecting obstacles and vehicles periodically within each service sector;

generating, at a local server, a remote control signal based on information about the obstacles and vehicles sensed by an infra sensor module within each service sector; and

transmitting, at the local server, the remote control signal to the remote control signal to the vehicle controller which had requested the driving guidance service.

14. The method of claim 13, wherein said generating a remote control signal includes:

receiving, at the local server, information of the divided service sector allocated from the global server;

collecting the information on the obstacles and the vehicles from the infra sensor module to store the information in a database;

upon the receipt of the request for the driving guidance service from the vehicle controller within the service sector, transmitting an inquiry message inquiring to the global server whether the vehicle controller requested for the driving guidance service is allowed to get the driving guidance service;

generating the remote control signal based on the collected information on the obstacles and the vehicles; and

transmitting the vehicle control information to the vehicle controller requesting the driving guidance service.

15. The method of claim 14, wherein the allocated network resources includes a frequency band through which the local server communicates with the vehicle controllers within the service sector and a communication time interval during which the local server communicates with each of the vehicle controllers requesting the driving guidance service.

16. The method of claim 14, wherein said generating a remote control signal further includes logging information about the in a list of the vehicles having the vehicle controllers which request the driving guidance service.

17. The method of claim 14, wherein said generating vehicle control information further includes:

broadcasting a checking packet to examine whether there is any vehicle controller to require participating in the driving guidance network to the vehicle controllers within the service sector.

18. The method of claim 13, further comprising giving a priority to the vehicles for the driving guidance service based on a preceding vehicle in the traveling direction thereof or the order of the request for driving guidance service.

19. The method of claim 13, wherein said allocating a local server further includes:

detecting a vehicle moves from a service sector where the vehicle has been served the vehicle guidance service to another service sector; and

transmitting a handover command to a local server in the another service sector.

20. The method of claim 17, further comprising:

upon receipt of the checking packet from the local server, determining whether or not there is a request for the driving guidance service to transmit a request message for the driving guidance service to the local server; and

upon receipt of the remote control signal from the local server, driving the vehicle based on the remote control signal.
