Research on Road Vehicle Positioning Technology based on UWB Communication

Abstract

In order to accelerate the construction of intelligent transportation network, we will design and develop a high-precision vehicle lane positioning platform for highway centimeters to realize the integration of vehicle and road clouds. The design of the highway vehicle precision positioning system is based on STM32F103CBT6, UWB chip as the core to achieve the design of anchor and tag. At the same time, by adding RF amplifiers, modifying the transmitting power and optimizing the software code, it is possible to achieve high precision long distance positioning in real time and guarantee 150m communication. Finally, the QT interface presents the vehicle's trajectory. Experimental results show that the system is stable and reliable, the positioning error can be achieved within 10cm, and the high refresh rate of the second can be achieved on the QT platform.
