| Abstract: | Map matching method plays an important role in vehicle location and navigation systems.It employs the information in a digital map to compensate the positioning error.This paper presents a fuzzy logic based probabilistic map matching algorithm used in GPS/INS integrated navigation systems,in which the reliability degree of map matching resolution is given explicitly as the decision basis in selecting matching road segment by utilizing the fuzzy comprehensive judgement.The results of experimental simulations have shown that the system performance gained significant enhancement by introducing this algorithm. |
