The accuracy of vehicle positioning is directly affected by the dynamic models. It is difficult to use a single model to describe vehicle movement precisely because of the variable motion in the running process of vehicles. By integrating the constant velocity (CV) model and the current statistical model(CSM) and introducing the adaptive switching mechanism,an algorithm for vehicle positioning and tracking is designed. The computation results are compared with those by the CSM, which verifies the effectiveness of the algorithm.
