PROBLEM TO BE SOLVED: To improve detection precision of an angle of inclination of a road and calculation precision of a current position. SOLUTION: An inclination angle detection device is configured to acquire information on an angleαof inclination of a vehicle by relearning, considering that weight distribution of the vehicle is changed when detecting a change of an output signal of a door opening/closing switch 12. Consequently, an angleθof inclination of the road on which the vehicle travels is correctly calculated, and a height position and a horizontal position of the vehicle are correctly calculated. The current position of the vehicle is therefore correctly calculated. COPYRIGHT: (C)2012,JPO&INPIT |
