Abstract-Intelligent vehicle driving performance is safe and stable, which can significantly improve the efficiency of road traffic and reduce energy consumption, and intelligent vehicle is also the development direction of modern transport. Its core technology is intelligent environment perception module, by using a variety of sensors on the car in which the surrounding environment for data collection, processing module to provide effective control for the basis. In this paper, a new SINS / CNS / GPS integrated navigation observation equation is proposed, and a new federated data fusion structure is designed for the integrated navigation system. The particle filter is used to fuse the multi-source data of the federated filter subsystem, thus eliminating the limitations of the classical Kalman filter. The traditional Kalman filter structure and the federal particle filter mechanism are designed. The comparison shows that the proposed algorithm is effective in the information fusion of the integrated navigation system, and the filtering effect is superior to the traditional filtering method.

IntroductionWith the progress of society, the car has become an essential travel means of transport, vehicle congestion, traffic accidents and other issues are increasingly apparent. The rapid growth in the number of cars is caused by the low efficiency of public transport which leads to frequent traffic accidents. The establishment of a modern intelligent transportation system will be mentioned on the agenda. Intelligent Vehicles, as an important part of Intelligent Transportation Systems, is also the main body of the system, which not only improves driving safety and road traffic efficiency, but also reduces energy consumption [1][2][3]. Due to many advantages, the technology research has been increasingly concerned about the relevant institutions at home and abroad. Intelligent transportation system can effectively relieve traffic pressure, rational allocation of public transport resources and road resources. Based on machine sensing technology and control technology, the driving system uses information transmission technology and computer vision technology helps to monitor the road 88
