METHOD AND SYSTEM FOR CONTROLLING RELATIVE POSITION BETWEEN VEHICLES USING A MOBILE BASE STATION
First Claim
1. A system for controlling a relative position between vehicles using a mobile base station, the system comprising:
- a mobile bases station configured to transmit a differential global positioning system (DGPS) correction data,the mobile base station including;
a first global positioning system (GPS) reception unit configured to receive GPS information from a satellite;
a position calculation unit configured to calculate current position information based on the received GPS information and a value detected by an internal sensor;
a DGPS correction data generation unit configured to generate a DGPS correction data based on the calculated position information and the GPS information received from the first GPS reception unit; and
a first V2X communication unit configured to transmit the DGPS correction data generated from the DGPS correction data generation unit to the control target vehicle; and
a control target vehicle configured to receive the DGPS correction data from the mobile base station and perform position control,the control target vehicle including;
a second V2X communication unit configured to receive the DGPS correction data transmitted from the first V2X communication unit of the mobile base station;
a second GPS reception unit configured to receive GPS information from a satellite;
a DGPS-based position information correction unit configured to calculate its own position information based on the DGPS correction data received from the second V2X communication unit and the GPS information received from the second GPS reception unit and perform position correction; and
a traveling control unit configured to control a speed and direction of a vehicle based on the position information output from the DGPS-based position information correction unit.

Abstract
A method and system of controlling a relative position between vehicles using a mobile base station is provided. GPS information is received from a satellite at a mobile base station and a target vehicle. The current position information the mobile base station is calculated with reference to a moving speed and direction based on the received GPS information. DGPS correction data is then generated by calculating the calculated position information and the received GPS information through a preset algorithm and the generated DGPS correction data is transmitted to one or more target vehicles. In the control target vehicle, the transmitted DGPS correction data is received, GPS information is received from a satellite, position information is calculated based on the received GPS information and the received DGPS correction data to execute position correction, and a speed and direction of the control target vehicle is adjusted according to the calculated position information.
