On-Board Diagnostics Based Navigation Device For Dead Reckoning
First Claim
1. A computing navigation device comprising a processor configured to execute:
- a communication module configured to receive a global positioning satellite (GPS) system signal corresponding to a vehicle position of a vehicle and configured to recognize a dropped signal condition in which no operational signal is detected from the GPS system, and configured to identify a last position of the vehicle corresponding to a time of the dropped signal condition, and configured to retrieve OBD data from an on-board diagnostics system of the vehicle corresponding with a movement of the vehicle;
a kinematic module configured to calculate a calculated position of the vehicle based on the last position and the OBD data; and
a graphical user interface configured to display a representation of the calculated position.

Abstract
A computing navigation device is disclosed that includes a processor configured to control a communication module configured to receive a global positioning satellite (GPS) system signal corresponding to a vehicle position of a vehicle. The processor may be further configured to recognize a dropped signal condition in which no operational signal is detected from the GPS system, and to identify a last position of the vehicle corresponding to a time of the dropped signal condition. The processor may be further configured to retrieve on-board diagnostics data from an on-board diagnostics system of the vehicle corresponding with a movement of the vehicle. The computing navigation device may further include a kinematic module configured to calculate a calculated position of the vehicle based on the last position and the movement of the vehicle, and a display configured to display a representation of the calculated position.

11. A method for dead reckoning, comprising:
-
receiving a GPS signal from a GPS system with a GPS receiver coupled with a moving vehicle; recognizing a lack of an operational signal from the GPS system as a dropped signal condition; passing a last position of the vehicle to a kinematic module upon reaching the dropped signal condition; retrieving OBD data corresponding with a continued movement of the vehicle from an on-board diagnostics system of the vehicle; calculating a calculated position of the vehicle with the kinematic module based on the last position of the vehicle and the OBD data; and displaying the calculated position of the vehicle on a graphical user interface. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A navigation system, comprising:
-
a computing navigation device configured to receive a operational GPS signal from a GPS system sufficient to track a position of the computing navigation device during a signal receiving condition, and to receive from an on-board diagnostic system of a vehicle OBD data indicative of a movement of the vehicle, the computing navigation device including; a processor configured to; monitor the GPS signal from the GPS system; recognize a dropped signal condition in which no operational GPS signal is detected from the GPS system; identify a last position of the vehicle upon reaching the dropped signal condition; receive OBD data from the on-board diagnostic system upon reaching the dropped signal condition; and calculate a calculated position of the vehicle based on the last position and the OBD data; and a display coupled with the processor and configured to display the tracked position during the signal receiving condition, and to display the calculated position during the dropped signal condition.
