Abstract:
PROBLEM TO BE SOLVED: To determine meandering movement with higher accuracy.SOLUTION: A direction change detection unit 117 determines that meandering movement is detected when a cumulative angle is greater than or equal to a prescribed value and assumes that meandering movement is detected when the cumulative angle is less than the prescribed value and an expansion angle is greater than or equal to a prescribed value. When it is determined that meandering movement is detected and a direction change point of a route exists within a prescribed range on the route in the direction of travel from the current estimated position, a matching unit 115 specifies a next estimated position along the route from the direction change point forward in the direction of travel on the basis of an acquired movement distance. On the other hand, when being nonexistent, the matching unit 115 determines that the user has come off the route. Furthermore, when it is assumed that meandering movement is detected and the direction change point exists within a prescribed range on the route in the direction of travel from the current estimated position, the matching unit 115 specifies a next estimated position along the route from the direction change point forward in the direction of travel on the basis of the movement distance, and when being nonexistent, specifies a next estimated position on the basis of the movement distance.SELECTED DRAWING: Figure 2
