Abstract
Methods and systems are provided for calculating a position of a vehicle on a road segment and updating a calibration of a heading sensor based on a lane change status of the vehicle. In one embodiment, a method includes receiving vehicle characteristic data from at least one vehicle sensor; receiving map data corresponding to a vehicle location; determining a lane change status of the vehicle; calculating the vehicle position using the map data if the vehicle has not executed a lane change maneuver and calculating the vehicle position using the vehicle characteristic data if the vehicle has executed a lane change maneuver, and calibrating a heading sensor based on one or more of the map data and the vehicle characteristic data.
