This vehicle positioning device is connected to a first sensor that outputs satellite positioning data, a second sensor that detects a vehicle state quantity and outputs the same as state quantity data, and at least one from among a third sensor that detects an object and outputs data about the relationship between the object and the vehicle and a fourth sensor that detects a road line shape and outputs the same as road line shape data. An observation value processing unit of this vehicle positioning device receives the satellite positioning data and at least one from among the relationship data and road line shape data and integrates the same so as to produce an actual observation value. A sensor correction unit is connected to the second sensor and corrects sensor error in the state quantity data. An inertial positioning unit uses a corrected sensor value corrected by the sensor correction unit to carry out inertial positioning and outputs the result of the inertial positioning. An observation value predict
