Abstract:
A position/attitude storage unit (3) retains the values of the present position and the present attitude. A road-end distance storage unit (6) determines a reference road end and a road-end distance. A traveling direction identification unit (4) identifies the traveling direction. A moving amount calculation unit (7) determines the moving distance after a preset period of time has elapsed. A position update unit (8) makes, on the basis of the road-end distance and the reference road end, and on the basis of the traveling direction and the moving distance, a movement by the amount of the moving distance in the traveling direction along the road-end shape of the reference road end from the present position and then updates the present position of the position/attitude storage unit (3) at a position situated at the road-end distance from the reference road end.
