Abstract

A vehicle information system is provided that includes an interface module configured to receive operating data from a vehicle information system. The interface module is also configured to transfer the operating data to a navigation system that is not built-in to the vehicle to facilitate vehicle position determination without using external positioning signals received or processed by the vehicle.

Claims

1. A vehicle communication network, comprising:

an interface module built-in to the vehicle and configured to receive operating data from a vehicle information system, and to selectively output the operating data to an off-board vehicle navigation system for determining vehicle position without using external positioning signals received or processed by the vehicle only while the external positioning signals are not available or are unreliable, wherein the off-board vehicle navigation system is positioned remote from the vehicle and is configured to receive operating data from a plurality of vehicles via respective vehicle communication networks.

2. The vehicle communication network of claim 1, wherein the interface module comprises a first interface configured to communicate with the vehicle information system, and a second interface configured to communicate with the off-board vehicle navigation system.

3. The vehicle communication network of claim 2, wherein the first interface comprises a CAN Bus interface, a FlexRay interface, an Ethernet interface, or a combination thereof.

4. The vehicle communication network of claim 2, wherein the second interface comprises a Bluetooth interface, a WiFi interface, cellular signals, or a combination thereof.

5. The vehicle communication network of claim 1, wherein the interface module is configured to receive signals indicative of route information, destination information, or a combination thereof, from the off-board vehicle navigation system.

6. The vehicle communication network of claim 1, wherein the off-board vehicle navigation system is configured to determine road conditions, traffic conditions, or a combination thereof, based on the operating data.

7. The vehicle communication network of claim 1, comprising an on-board controller configured to determine vehicle position based on the external positioning signals.

8. The vehicle communication network of claim 7, wherein the off-board vehicle navigation system is configured to selectively receive signals indicative of the vehicle position from the on-board controller while the external positioning signals are available.

9. The vehicle communication network of claim 1, wherein the operating data comprises vehicle speed, compass heading, distance traveled, steering angle, yaw rate, acceleration, brake pedal position, antilock braking system activation, stability control system activation, regenerative braking activation, or a combination thereof.

10. The vehicle communication network of claim 1, wherein the vehicle information system comprises a speed sensor, an electronic compass, a transmission sensor, an antilock braking system, a stability control system, an electric motor controller, or a combination thereof.

11. A vehicle communication network, comprising:

a vehicle information system configured to output operating data;

an on-board controller configured to determine a position of a vehicle based on external positioning signals;

an off-board vehicle navigation system configured to selectively receive signals indicative of the vehicle position from the on-board controller while the external positioning signals are available; and

an interface module built-in to the vehicle and configured to receive the operating data from the vehicle information system, and to selectively output the operating data to the off-board vehicle navigation system for determining the vehicle position without using the external positioning signals only while the external positioning signals are not available or are unreliable;

wherein the off-board vehicle navigation system is positioned remote from the vehicle and is configured to receive operating data from a plurality of vehicles via respective vehicle communication networks.

12. The vehicle communication network of claim 11, wherein the operating data comprises vehicle speed, compass heading, distance traveled, steering angle, yaw rate, acceleration, brake pedal position, antilock braking system activation, stability control system activation, regenerative braking activation, or a combination thereof.

13. The vehicle communication network of claim 11, wherein the off-board vehicle navigation system is configured to determine road conditions, traffic conditions, or a combination thereof, based on the operating data.

14. The vehicle communication network of claim 11, wherein the interface module comprises a first interface configured to communicate with the vehicle information system, and a second interface configured to communicate with the off-board vehicle navigation system.

15. The vehicle communication network of claim 14, wherein the second interface comprises a Bluetooth interface, a WiFi interface, cellular signals, or a combination thereof.

16. A vehicle communication network, comprising:

an interface module built-in to the vehicle and configured to receive operating data from a vehicle information system, and to selectively transfer the operating data to an on-board spatial locating device only while external positioning signals are not available or are unreliable, wherein the on-board spatial locating device is not built-in to the vehicle, and the operating data facilitates vehicle position determination without using the external positioning signals; and

an electrical outlet positioned within an interior of the vehicle, wherein the electrical outlet is configured to receive a corresponding electrical connector of the on-board spatial locating device and to supply electrical power to the on-board spatial locating device via a direct current power signal, and the interface module is configured to transfer the operating data to the on-board spatial locating device by modulating the direct current power signal.

17. The vehicle communication network of claim 16, wherein the interface module comprises a first interface configured to communicate with the vehicle information system, and a second interface configured to communicate with the on-board spatial locating device.

18. The vehicle communication network of claim 17, wherein the first interface comprises a CAN Bus interface, a FlexRay interface, an Ethernet interface, or a combination thereof.

19. The vehicle communication network of claim 16, wherein the operating data comprises vehicle speed, compass heading, distance traveled, steering angle, yaw rate, acceleration, brake pedal position, antilock braking system activation, stability control system activation, regenerative braking activation, or a combination thereof.

20. The vehicle communication network of claim 16, wherein the electrical outlet comprises a cigarette lighter receptacle.
