Abstract

A system determines dew point and temperatures through a mobile platform. The system identifies a likelihood of condensation forming on a roadway surface. A controller may process the data to determine the likelihood of frost, ice, and/or black ice conditions. Some systems provide aural, visual, and/or tactile signals or feedback to identify a condition or a change in conditions. The change, condition, and/or data may be associated with position data.

Claims

1. A system that determines air temperatures and humidity from a mobile platform comprising:

a first mobile sensor that measures a dew point and an ambient air temperature;

a second mobile sensor that measures a roadway surface temperature; and

a mobile processor that processes sensor data from the first sensor and the second sensor to determine the likelihood of condensation forming on the roadway surface;

where the processor is programmed to determine the likelihood of the condensation forming frost, ice, or black ice on the roadway surface.

2. The system of claim 1 further comprising an interface that connects the processor to a user interface in a vehicle.

3. The system of claim 1 further comprising a transceiver that transmits sensor information to a remote destination from the processor.

4. The system of claim 1 further comprising a transceiver configured to transmit the processed data and location data of a vehicle when a measured weather condition changes.

5. The system of claim 2 where the graphical user interface generates indicators identifying weather conditions based upon measured and derived data elements generated by the processor.

6. The system of claim 1 further comprising a transceiver configured to wirelessly transmit the processed in vehicle data to a remote Internet site.

7. The system of claim 1 further comprising a transceiver configured to wirelessly transmit a plurality of dew point data packets to a remote server in real-time.

9. The system of claim 1 where the processor is programmed to generate a visual or an auditory signal that indicates the presence of the frost, the ice, or the black ice condition.

10. The system of claim 1 further comprising a transceiver programmed to transmit sensor data to a remote location as sensor data is processed by an in-vehicle processor.

11. A system that compares surface temperature and dew point in a mobile environment comprising:

a first mobile sensor that measures a dew point and an ambient air temperature;

a cover assembly that forms an uninterrupted curved airway that originates at an air inlet and terminates at an air outlet that feeds an enclosed air pocket that partially surrounds the first mobile sensor;

a second mobile sensor that measures roadway surface temperature; and

an in-vehicle processor that processes sensor data from the first sensor and the second sensors and predicts the likelihood of condensation forming on the roadway surface at a plurality locations while the first mobile sensor, the cover assembly, the second mobile sensor and the in-vehicle processor are in motion.

12. The system of claim 11 further comprising a transmitter configured to transmit data to a local and a remote destination.

13. The system of claim 12 where the in-vehicle processor is programmed to compare dew point data to the ambient air temperature data and roadway surface temperature data in the vehicle to predict the likelihood that the condensation forms a frost, an ice, or a black ice condition.

14. The system of claim 12 where the transmitter couples a first vehicle and communicates with a mesh network that conveys the sensor data to a second vehicle.

15. The system of claim 12 where the transmitter couples a first vehicle and communicates with a stationary network that conveys the sensor data to a second vehicle.

16. The system of claim 12 where the transmitter couples a first vehicle and communicates with a stationary network.

17. The system of claim 11 where the cover assembly comprises a plurality of cylindrical truncated elements that forms the air inlet, air outlet, and the airway.

18. The system of claim 17 further comprising a filter tube disposed between the air inlet and the air outlet.

19. A system that compares air temperature and dew point data in a mobile environment comprising:

a first mobile sensor that measures a dew point and an ambient air temperature;

a cover assembly that forms an uninterrupted airway that originates at an air inlet and terminates at an air outlet and feeds an air filter and an enclosed air pocket formed by the cover assembly, where the cover assembly and the air filter partially surrounds the first mobile sensor;

a second mobile sensor that measures roadway surface temperature;

an in-vehicle processor that processes sensor data from the first mobile sensor and the second mobile sensor and predicts the likelihood of condensation forming on the roadway surface; and

a local in-vehicle bus that facilities a data transfer between the in-vehicle processor and the first mobile sensor.

20. The system of claim 19 where the vehicle processor communicates with an in-vehicle transmitter that conveys the results to an in-vehicle display.

21. The system of claim 20 further comprising an output device that generates a visual and an audible warning when the in-vehicle processor predicts a likelihood of the condensation forming frost, ice, or black ice condition on the roadway surface.

22. The system of claim 19 further comprising a transmitter configured to transmit the sensor data to a display and to a remote server based in part on the vehicle processor'"'"'s comparison of a dew point to a measured roadway surface temperature.
