| Abstract: | The function of map matching algorithm in GPS/DR integrated navigation is studied. The factor which affects the precision of map matching is analyzed. Map matching method based on fuzzy logic is simulated. Fuzzy-integrated judge is done by using direction, road-section approach degree and comparability, and in combining the topology of road network, the best matching road section is elected. The result of computer simulation has proved the validity of this method. |
