| Abstract: | The paper introduced the basic frame of vehicle location and navigation system, which is divided seven function modules. One kind of data structure of navigation electronic map is proposed. The truth degree for map matching calibration and its implementation algorithm are presented based on the fuzzy logic comprehensive judgment theory, which provides explicit references in evaluating the reliability of map matching results. Based on the analysis of optimal route guidance theory, a high efficient implementation method of hierarchical searching algorithm is proposed. Finally, the system design and the application of vehicle location & navigation are investigated and an original design scheme based on the above research works is presented. |
