摘要
车辆定位精度与采用的动力学模型直接相关。文章针对单一的动力学模型难以精确描述车辆行驶过程中的运动状态变化,提出复合CV模型和CSM模型,引入自适应切换机制,设计一种车辆定位跟踪算法。通过与CSM模型实验结果进行比较,验证了该算法的优越性。
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.
