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.

Abstract: A vehicle telematics device for a vehicle that includes an electronic processor, a wireless chipset for wireless communication to and from the vehicle, and a bus interface for receiving bus messages from a communications bus in the vehicle. The vehicle telematics device includes computer readable memory storing program code that, upon execution by the processor, causes the vehicle telematics device to: (a) monitor for messages received by the bus interface from the communications bus; (b) detect a communication failure of the communication bus based on the monitoring; (c) determine a vehicle movement that is indicative of a vehicle crash; and (d) initiate a communication with a remote facility in response to both the detection of the communication failure and the determination of the vehicle movement that is indicative of a crash a notification.

Abstract: Embodiments include methods, systems and computer readable storage medium for a method for making temporal corrections to position data received a plurality of components. The method includes receiving, by a processor, vehicle location data and a time stamp associated with the vehicle location data from one or more components. The method further includes calculating, by the processor, a time difference between the time stamp and a current time received from the one or more components. The method further includes determining, by the processor, a time offset using the time difference and a distance travelled between the time stamp and an occurrence of the determination for each of the one or more components. The method further includes providing, by the processor, a corrected vehicle location using the time offset for each of the one or more component.

Abstract: A method of determining position includes providing a GNSS positioning receiver, a controller, and a non-transient computer-readable data storage. The data storage is provided with at least one 3-dimensional building model having a geographical identifier. The method also includes receiving at least one GNSS position signal. The method further includes calculating an approximate position based on the at least one GNSS position signal and that a respective GNSS position signal of the at least one GNSS position signal is a non-line-of-sight signal. The method further includes calculating, based on the building model and the respective GNSS position signal, a modeled position, and refining the modeled position based on a current heading and speed of the positioning receiver and a carrier-phase of the at least one GNSS position signal. The method still further includes calculating a final position based on the approximate position, the modeled position, and the refining step.
