Abstract

Methods and systems are provided for using remote sensor data for a vehicle. The vehicle includes a control system, an interface, and a processor. The interface is configured to automatically obtain one or more remote sensor values via a wireless network from a remote source that is remote from the vehicle. The processor is coupled to the control system and the interface, and is configured to control one or more functions of the control system using the one or more remote sensor values.

Claims

1. A method comprising:

automatically obtaining, via an interface onboard a vehicle, one or more remote sensor values via a wireless network from a remote source that is remote from the vehicle;

obtaining one or more vehicle sensor values from one or more sensors that are disposed onboard the vehicle;

comparing the one or more remote sensor values with the one or more vehicle sensor values, generating a comparison between the one or more remote sensor values and the one or more vehicle sensor values; and

controlling, via a processor, one or more functions of the vehicle using the comparison between the one or more remote sensor values and the one or more vehicle sensor values.

2. The method of claim 1, wherein the vehicle includes a front dash having a front dash display, and the step of controlling the one or more functions comprises automatically providing the one or more remote sensor values on the front dash display.

3. The method of claim 1, wherein the vehicle includes an engine and an engine control system, and the step of controlling the one or more functions comprises using the comparison between the one or more remote sensor values and the one or more vehicle sensor values in the engine control system for controlling one or more functions of the engine.

4. The method of claim 1, wherein the one or more remote sensor values are selected from the group consisting of:

one or more temperature values, one or more barometric pressure values, and one or more humidity values from the remote source.

5. The method of claim 1, wherein:

the step of comparing the one or more remote sensor values with the one or more vehicle sensor values comprises calculating a difference between the one or more remote server values and the one or more vehicle sensor values; and

the method further comprises providing a notification if the difference is greater than a predetermined threshold.

6. The method of claim 1, wherein:

the step of comparing the one or more remote sensor values with the one or more vehicle sensor values comprises calculating a difference between the one or more remote server values and the one or more vehicle sensor values; and

the step of controlling the one or more functions of the vehicle comprises controlling, via the processor, the one or more functions of the vehicle using an average of the one or more remote sensor values and the one or more vehicle sensor values, if the difference is greater than a predetermined threshold.

7. The method of claim 1, wherein:

the step of comparing the one or more remote sensor values with the one or more vehicle sensor values comprises calculating a difference between the one or more remote server values and the one or more vehicle sensor values; and

the step of controlling the one or more functions of the vehicle comprises controlling, via the processor, the one or more functions of the vehicle using the remote sensor values and not the vehicle sensor values, if the difference is greater than a predetermined threshold.

8. The method of claim 1, wherein:

the step of comparing the one or more remote sensor values with the one or more vehicle sensor values comprises calculating a difference between the one or more remote server values and the one or more vehicle sensor values; and

the step of controlling the one or more functions of the vehicle comprises controlling, via the processor, the one or more functions of the vehicle;

using an average of the one or more remote sensor values and the one or more vehicle sensor values, if the difference is greater than a first predetermined threshold; and

using the remote sensor values and not the vehicle sensor values, if the difference is greater than a second predetermined threshold.

9. A system comprising:

an interface disposed onboard a vehicle, the vehicle including a front dash having a front dash display, the interface configured to automatically obtain one or more remote sensor values via a wireless network from a remote source that is remote from the vehicle; and

a processor coupled to the interface, the processor configured to automatically provide the one or more remote sensor values on the front dash display of the vehicle;

wherein;

the interface is configured to obtain one or more vehicle sensor values from one or more sensors onboard the vehicle; and

the processor is configured to conduct a rationality check for the one or more vehicle sensor values using the one or more remote sensor values.

10. The system of claim 9, wherein:

the vehicle includes an engine and an engine control system; and

the processor is configured to use the one or more remote sensor values in the engine control system for controlling one or more functions of the engine.

11. The system of claim 9, wherein the one or more remote sensor values are selected from the group consisting of:

one or more temperature values, one or more barometric pressure values, and one or more humidity values from the remote source.

12. The system of claim 9, wherein the interface is configured to obtain the one or more remote sensor values from a weather station via the wireless network.

13. The system of claim 9, wherein the interface is configured to obtain the one or more remote sensor values from one or more additional vehicles via the wireless network.

14. The system of claim 9, wherein:

the interface is configured to obtain the remote sensor values from multiple remote sources that are remote from the vehicle, the multiple remote sources each having a respective distance from the vehicle; and

the processor is configured to;

generate one or more interpolated values by interpolating the remote sensor values utilizing the respective distances of the multiple remote sources from the vehicle; and

automatically controlling one or more functions for operation of the vehicle using the one or more interpolated values.

15. The system of claim 9, wherein the processor is configured to provide a notification if an error is detected for the one or more sensors onboard the vehicle based on the rationality check.

16. The system of claim 9, wherein the processor is further configured to mathematically approximate position specific data by applying a non-linear curve fit to existing sensor values from sensors onboard the vehicle.

17. The system of claim 9, wherein the processor utilizes stationary sensor values to evaluate ambient temperature conditions for a vehicle.
