Abstract

A vehicle system is in communication with a mobile device. The vehicle system receives information from the mobile device and determines the quality of the information. If the quality of the information is acceptable, the vehicle system may use the information from the mobile device. In addition, the quality of the information may be used to determine if the information should be sent to other vehicles.

First claim

What is claimed is:

1. A vehicle system for a motor vehicle comprising:
an electronic control unit configured for installation and use as part of a motor vehicle;
an onboard navigation system;
an interface configured for enabling communication between the onboard navigation system and a mobile device;
a display device; and
a computer-readable medium in communication with the electronic control unit having stored thereon computer-readable instructions for instructing the electronic control unit to perform actions comprising:
receiving information from the mobile device;
computing a mobile device validity and quality rating for the information received from the mobile device;
computing an onboard validity and quality rating for information from the onboard navigation system;
evaluating the mobile device quality rating to determine whether the information received from the mobile device is accurate;
notifying a user, via the display device, whether the information received from the mobile device is determined to be accurate;
prompting the user, via the display device, to select whether to integrate at least one feature of the mobile device; and
integrating the at least one feature of the mobile device with the onboard navigation system for receiving further information from the mobile device when the information received from the mobile device is determined to be accurate and when the user selects, via the display device, to integrate the at least one feature of the mobile device.

2. The vehicle system according to claim 1 , wherein the computer-readable instructions for instructing the electronic control unit to perform actions further comprise:
transmitting the information from the mobile device to another vehicle via vehicle-to-vehicle communications.

3. The vehicle system according to claim 1 , wherein the computer-readable instructions for instructing the electronic control unit to perform actions further comprise:
determining the information received from the mobile device is accurate if the mobile device quality rating meets a quality threshold.

4. The vehicle system according to claim 3 , wherein the quality threshold includes the information received from the mobile device substantially matching map information associated with the onboard navigation system.

5. The vehicle system according to claim 4 , wherein the quality threshold includes a match between data point locations of the information received from the mobile device and data point locations of map data from the onboard navigation system within a predetermined variance.

6. The vehicle system according to claim 4 , wherein the map information includes data for mapped objects and sensor feedback information for mapped objects sensed by the onboard navigation system.

7. The vehicle system according to claim 6 , wherein the quality threshold includes data point locations of the information received from the mobile device matching data point locations of the map data and sensed object information.

8. The vehicle system according to claim 1 , wherein evaluating the mobile device quality rating of the information from the mobile device includes performing location information error analysis calculations for the information received from the mobile device.

9. The vehicle system according to claim 8 , wherein performing location information error analysis calculations includes performing error computations selected from the group consisting of: user equivalent range error calculations (UERE), position dilution of precision calculations (PDOP), geometric dilution of precision computations (GDOP), interference calculations, and receiver autonomous integrity monitoring calculations (RAIM).

10. The vehicle system according to claim 1 , wherein the further information received from the mobile device is used to augment navigation information of the onboard navigation system.

11. The vehicle system according to claim 1 , wherein integrating the mobile device with the navigation system for receiving the further information from the mobile device includes setting the further information as a primary source of information over the information from the onboard navigation system.

12. The vehicle system according to claim 1 , wherein the computer-readable instructions for instructing the electronic control unit to perform actions further comprise:
comparing the mobile device validity and quality rating of the information received from the mobile device with the onboard validity and quality rating of the information from the onboard navigation system; and
setting the mobile device as the primary source for information over the onboard navigation system when the mobile device validity and quality rating of the information received from the mobile device is higher than the onboard validity and quality rating of the information from the onboard navigation system.

13. A method for providing navigation information for a motor vehicle, the method comprising:
automatically sensing a presence of a mobile device proximate the motor vehicle;
establishing communications between an onboard navigation system of the motor vehicle and the mobile device;
receiving information from the mobile device;
computing a mobile device validity and quality rating for the information received from the mobile device;
computing an onboard validity and quality rating for information from the onboard navigation system;
evaluating the mobile device quality rating to determine whether the information received from the mobile device is accurate;
notifying a user, via a display device, whether the information received from the mobile device is accurate;
prompting the user, via the display device, to select whether to use the information received from the mobile device to augment an operation of the onboard navigation system;
using the information received from the mobile device to augment the operation of the onboard navigation system when the information received from the mobile device is determined to be accurate and when the user selects, via the display device, to use the information received from the mobile device; and
preventing the onboard navigation system from using the information received from the mobile device when the information received from the mobile device is determined to be inaccurate and when the user selects, via the display device, not to use the information received from the mobile device.

14. The method according to claim 13 , further comprising:
determining the information received from the mobile device is accurate if the mobile device quality rating meets a quality threshold.

15. The method according to claim 14 , wherein the quality threshold is determined by comparing the information received from the mobile device with map information associated with the onboard navigation system.

16. The method according to claim 13 , wherein the information received from the mobile device is used as a primary source of information over the onboard navigation system when the mobile device quality rating of information from the mobile device is greater than the onboard quality rating of information determined for the onboard navigation system and when the user selects, via the display device, to use the information received from the mobile device.

17. The method according to claim 13 , wherein the information received from the mobile device is map information.

18. The method according to claim 13 , wherein the information received from the mobile device is image information.
