Claim 3:
4. The vehicle positioning device according to claim 1, wherein
the vehicle positioning device is connected to the first, second, and fourth sensors, and is connected to a road information storage storing road information,
the vehicle positioning device further comprises a road line shape calculator configured to calculate a road line shape used in calculation of the predicted observed value in the observed value prediction circuitry,
the road line shape calculator calculates the road line shape by using the road information stored in the road information storage,
the observed value processing circuitry generates the actual observed value by integrating the satellite positioning data and the road line shape data, and
the observed value prediction circuitry calculates the predicted observed value by using the inertial positioning results and the road line shape calculated in the road line shape calculator.
