A study of the High-speed vehicle real-time accurate positioning algorithm

Accurate real-time vehicle location technology in the fast-moving condition is one of the core content of the research field of vehicle active safety and automatic driving. The traditional technologies, like vehicular device-based distance sensors, satellite positioning, roadside beacon, the electronic map matching, are difficult to achieve precise positioning of the vehicle at high speed. In this paper, the self-adaptive and self-organizing local wireless mobile networks is built on the basis of V2V/V2R High-speed wireless self-organized communication (WAVE IEEE 802.11p) technology, and the vehicle location in fast-moving is realized on the basis of vehicle-road collaboration with RFID technology. Then the model of real time differential positioning of vehicle is established utilized high-speed self-organizing network, focusing on solving the error compensation of high-speed mobile positioning, and the corresponding algorithm for real-time positioning is designed in this article. The simulation results show that the research idea is feasible.
