Research on Vehicle Motion Equation Location Principle and Its Application

Utilizing the vehicle movement equation to obtain the vehiclei¯srunning distance, and regarding the road direction of the present position of vehicle as the direction angle, the vehicle position in real time was reckoned according to the dead reckon principlei¤The applications of this location technology in in-vehicle navigation system and control center were analyzed by field experimenti¤The field experimental result show that (1) the technol can realize the vehicle navigation in blind area of GPS; (2) the technology can reduce the flow of information between the individual vehicle and control center greatly theoretically in control centeri¤Its practical application still awaits further perfection of the Intelligent Transport Systemsi¤
