Abstract

A method and system for collecting meteorological data. A plurality of vehicles travel on roads in a geographic region. Each of the vehicles includes sensor equipment that senses at least one meteorological condition. The sensor equipment may be used to support other vehicle systems, such as vehicle safety systems or a vehicle navigation system. Each of the vehicles includes a program run on a computing device in the vehicle that prepares messages containing data indicative of the one or more meteorological conditions sensed by the sensor equipment. The messages are sent wirelessly from the vehicle to a meteorological data collection service that collects the data and uses the data for weather modeling or forecasting.

Claims

1. A method of collecting meteorological data comprising:

receiving messages from each of a plurality of vehicles traveling along roads in a geographic region, wherein each message includes meteorological data pertaining to the geographic region; and

using said meteorological data from said plurality of vehicles for weather forecasting, wherein said weather forecasting predicts a future state of meteorological conditions for the geographic region including off-road portions of the geographic region.

2. The method of claim 1 wherein each message also includes data indicating a time that said meteorological data was collected.

3. The method of claim 1 wherein said meteorological data comprises data indicating temperature.

4. The method of claim 1 wherein each of said messages includes data indicating a geographic position at which said meteorological data was collected.

5. The method of claim 1 wherein each of said messages includes data indicating an RDS/TMC location reference code indicating a geographic position at which said meteorological data was collected.

6. The method of claim 1 wherein said meteorological data comprises data indicating precipitation.

7. The method of claim 1 further comprising:

prior to the step of receiving, collecting meteorological data with each of said plurality of vehicles using sensor equipment installed in each of said plurality of vehicles.

8. The method of claim 7 further comprising:

prior to the step of receiving, transmitting said messages from each of said plurality of vehicles.

9. The method of claim 7 further comprising:

in at least some of said plurality of vehicles, using said meteorological data collected with said sensor equipment in a safety system installed in the vehicle.

10. The method of claim 7 further comprising:

in at least some of said plurality of vehicles, using said meteorological data collected with said sensor equipment in a navigation system in the vehicle.

11. The method of claim 1 further comprising:

transmitting RDS/TMC messages that include weather-related information derived from the meteorological data from each of said plurality of vehicles.

12. The method of claim 1 further comprising:

determining positions of the plurality of vehicles remotely using equipment that indicates locations from which the messages were sent.

13. A method of collecting meteorological data comprising:

gathering meteorological data with a plurality of vehicles that are traveling along roads in a geographic region;

transmitting data messages wireless from the plurality of vehicles that are traveling along roads in the geographic region, wherein each data message includes meteorological data; and

using said meteorological data from said plurality of vehicles for weather modeling, wherein said weather modeling simulates meteorological conditions for the geographic region including off-road portions of the geographic region.

14. The method of claim 13 wherein each of said data messages also includes data indicating a geographic position at which the meteorological data in said message was collected.

15. The method of claim 13 wherein each of said data messages also includes data indicating a time that said meteorological data included in said data message was collected.

16. The method of claim 13 wherein said meteorological data comprises data indicating temperature.

26. The method of claim 13 wherein said weather modeling provides a map of isotherms.

17. A meteorological data collection system comprising:

a plurality of vehicles each of which is equipped with sensor equipment that senses at least one meteorological condition and a wireless communication system that sends data representing the meteorological condition sensed by said sensor equipment; and

a meteorological data collection service that collects the data transmitted from each of said plurality of vehicles and uses said data for weather modeling that simulates meteorological conditions or forecasting that predicts a future state of meteorological conditions for the geographic region including off-road portions of the geographic region.

18. The invention of claim 17 wherein at least some of said plurality of vehicles includes a navigation system that receives data from the sensor equipment.

19. The invention of claim 17 wherein at least some of said plurality of vehicles includes at least one safety system that receives data from the sensor equipment.

20. The invention of claim 17 wherein said meteorological condition represented by said data is temperature.

21. The invention of claim 17 wherein said meteorological condition represented by said data is precipitation.

22. The invention of claim 17 wherein said meteorological condition represented by said data is barometric pressure.

23. The invention of claim 17 wherein each of said plurality of vehicles also sends data indicating a geographic location.

24. The invention of claim 17 wherein each of said plurality of vehicles also sends data indicating a time associated with said meteorological condition.

25. A business model for collection meteorological data comprising:

gathering meteorological data with a plurality of vehicles that are traveling along roads in a geographic region, wherein each of said plurality of vehicles is equipped with sensor equipment that senses at least one meteorological condition and a wireless communication system that sends data representing the meteorological conditions sensed by said sensor equipment;

using said meteorological data from said plurality of vehicles for simulating or predicting meteorological conditions for the geographic region including off-road portions of the geographic region; and

in exchange for receiving meteorological data from said plurality of vehicles, providing said vehicles with weather-related data.

27. A method of collecting meteorological data comprising:

receiving messages from each of a plurality of vehicles traveling along roads in a geographic region, wherein each message includes meteorological data pertaining to the geographic region; and

using said meteorological data from each of said plurality of vehicles for weather modeling or forecasting to provide meteorological conditions for the geographic region including off-road portions of the geographic region.
