Problems solved by technology

However, since a complicated technique for accurately controlling relative positions between vehicles using DGPS, etc. is required, considerable cost is required, so that necessary sensors and devices must be installed in each vehicle
[0006] In some cases, the exact location of the vehicle cannot be accurately discovered, so there is a need for techniques to improve the relative position accuracy between vehicles
However, DGPS as described above is limited to fixed base station locations
Therefore, when commercial DGPS correction data is used and the vehicle is located far from the base station, the position accuracy cannot be improved even with DGPS

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.

Description

technical field [0001] The present invention relates to a technology for controlling the relative position between vehicles, and more particularly to a method and system for controlling the relative position between vehicles by using a mobile base station, which improves the accuracy of the relative position between vehicles and performs position Control, while communicating with the vehicle acting as a mobile base station for the Differential Global Positioning System (DGPS), via vehicle-to-vehicle (V2X) communication. Background technique [0002] Global Positioning System (GPS) A space-based satellite navigation system that provides location and time information to remote devices located anywhere on or near Earth. However, in order for most GPS devices to function properly, there must generally be an unobstructed line of sight for four or more GPS satellites. These systems are freely available to anyone with the aid of a GPS receiver. [0003] Most GPSs have a typical k...
