Claims (1)
し、推定現在地が地図情報の道路状況に合致しな
いときは、該推定現在地を妥当な道路の中心線上
に移動させ、地図情報との整合を図る車載用航法
装置であつて、車両が幅員が大きい道路を左折し
たときは右折したときより推定現在地の進む距離
を大きくして前記整合に供する補正手段を設けて
なる車載用航法装置。 An in-vehicle system that estimates the current location based on the vehicle's travel distance and direction, and when the estimated current location does not match the road conditions in the map information, moves the estimated current location to the center line of the appropriate road to match the map information. This on-vehicle navigation device is provided with a correction means for making the distance traveled by the estimated current location larger when the vehicle turns left on a wide road than when turning right, thereby providing for the alignment.
