Patent number: 5311173Abstract: In a navigation system which has sensors for detecting a running distance, an azimuth, etc. of a vehicle, and a memory for storing map data; a probability density of a position of the vehicle is calculated on the basis of the sensor outputs and the map data for each of quantization units with which a probability computation determined by detection accuracies of the sensors and quantization of the map data can be executed. In addition, a final stage calculation of DP matching between trajectory data obtained from the on-board sensor data from a start point of the vehicle until a current time and a candidate route estimated from the road map data is iteratively executed, whereby a plurality of estimative vehicular positions and uncertainties (costs) corresponding to the respective estimative positions are iteratively evaluated, and a correct vehicular position is estimated by selecting at least one estimative vehicular position of low uncertainty (cost).Type: GrantFiled: August 28, 1991Date of Patent: May 10, 1994Assignee: Hitachi, Ltd.Inventors: Fuminobu Komura, Yoshikazu Hirayama, Koichi Homma, Makoto Kato, Takanori Shibata, Yoji Matsuoka, Akira Kagami, Michitaka Kosaka
