Methods and systems for vehicle positioning feedback

1. A method of calculating a position of a vehicle on a road segment, the method comprising:

providing the vehicle with at least one vehicle sensor and a controller in electronic communication with the at least one vehicle sensor, wherein the at least one vehicle sensor comprises a vehicle heading sensor;

receiving, by the controller, vehicle characteristic data corresponding to at least one vehicle characteristic from the at least one vehicle sensor;

receiving, by the controller, map data corresponding to a vehicle location;

determining, by the controller, a lane change status indicating whether the vehicle has executed a lane change maneuver within a calibratable time interval;

calculating, by the controller, the vehicle position using the map data in response to the vehicle not having executed a lane change maneuver within the calibratable time interval;

calculating, by the controller, the vehicle position using the vehicle characteristic data in response to the vehicle having executed a lane change maneuver within the calibratable time interval;

calibrating, by the controller, the vehicle heading sensor using the map data in response to the lane change status indicating the vehicle has not executed a lane change maneuver within the calibratable time interval; and

calibrating, by the controller, the vehicle heading sensor using the vehicle characteristic data in response to the lane change status indicating the vehicle has executed a lane change maneuver within the calibratable time interval.

2. The method of claim 1 , wherein the at least one vehicle sensor includes one or more of an accelerometer, a vehicle speed sensor, and an optical sensor.

3. The method of claim 2 , wherein the map data includes lane information of a mapped road segment.

4. The method of claim 3 , wherein the vehicle characteristic data is indicative of one of crossing a lane boundary of a road lane and maintaining a vehicle trajectory within the road lane.

5. The method of claim 4 , wherein the vehicle not having executed the lane change maneuver comprises the vehicle maintaining the vehicle trajectory within the road lane.

6. The method of claim 4 , wherein the vehicle executing the lane change maneuver comprises the vehicle crossing the lane boundary of the road lane.

7. An automotive vehicle, comprising:

a vehicle body and a plurality of wheels coupled to the vehicle body;

at least one vehicle sensor configured to detect at least one vehicle characteristic, wherein the at least one vehicle sensor comprises a vehicle heading sensor; and

a controller in communication with the at least one vehicle sensor, the controller configured to

receive vehicle characteristic data corresponding to the at least one vehicle characteristic from the at least one vehicle sensor;

receive map data corresponding to a location of the vehicle;

determine a lane change status indicating whether the vehicle has executed a lane change maneuver within a calibratable time interval;

calculate the vehicle position using the map data in response to the vehicle not having executed a lane change maneuver within the calibratable time interval;

calculate the vehicle position using the vehicle characteristic data in response to the vehicle having executed a lane change maneuver within the calibratable time interval;

calibrate the vehicle heading sensor using the map data in response to the lane change status indicating the vehicle has not executed a lane change maneuver within the calibratable time interval; and

calibrate the vehicle heading sensor using the vehicle characteristic data in response to the lane change status indicating the vehicle has executed a lane change maneuver within the calibratable time interval.

8. The automotive vehicle of claim 7 , wherein the at least one vehicle sensor includes one or more of an accelerometer, a vehicle speed sensor, and an optical sensor.

9. The automotive vehicle of claim 8 , wherein the map data includes lane information of a mapped road segment.

10. The automotive vehicle of claim 9 , wherein the vehicle characteristic data is indicative of one of crossing a lane boundary of a road lane and maintaining a vehicle trajectory within the road lane.

11. The automotive vehicle of claim 9 , wherein calculating the vehicle position using the map data comprises matching the vehicle position to the map data.

12. The automotive vehicle of claim 8 , wherein calculating the vehicle position using the vehicle characteristic data comprises updating the vehicle position.

13. A system for calculating a position of a vehicle on a road segment, comprising:

at least one vehicle sensor configured to detect a vehicle characteristic, the at least one vehicle sensor comprising a vehicle heading sensor; and

a controller in communication with the at least one sensor, the controller configured to receive map data corresponding to a location of a vehicle, receive vehicle characteristic data corresponding to the at least one vehicle characteristic from the at least one vehicle sensor, determine a lane change status indicating whether the vehicle has executed a lane change maneuver within a calibratable time interval, calculate the vehicle position and calibrate the vehicle heading sensor using the vehicle characteristic data in response to the vehicle having executed a lane change maneuver within the calibratable time interval, and otherwise calculate the vehicle position and calibrate the vehicle heading sensor using the map data in response to the vehicle not having executed a lane change maneuver within the calibratable time interval.

14. The system of claim 13 , wherein the at least one vehicle sensor includes one or more of an accelerometer, a vehicle speed sensor, and an optical sensor.
