法装置。 An in-vehicle navigation device that estimates the current location of a vehicle from the outputs of a direction sensor and a mileage sensor and displays it on a road map, which regards the road described on the road map as a set of straight lines connecting nodes at both ends. When the created road information table is given and the vehicle changes its course, if it has been traveling straight until then, it will match the estimated current location to a node with high reality validity and drive on a continuously curving road. An on-vehicle navigation device equipped with a map matching means that interrupts matching until the vehicle continues to travel straight for a certain distance.
