Abstract

Data acquisition from a sampling of vehicle sensors includes identifying a vehicle population density for a defined region, calculating a proportional representation ratio from the vehicle population density, and transmitting a request for data over a network. The request includes the response criteria configured with the proportional representation ratio. The data acquisition also includes receiving the data from vehicles that are located in the defined region and that fall within the proportional representation ratio, and which meet the response criteria.

Claims

1. A system for data acquisition from a sampling of vehicle sensors, comprising:

a host system computer; and

logic executable by the host system computer, the logic configured to;

identify a vehicle population density representing a number of vehicles in a defined region, each of the vehicles corresponding to the vehicle population density having communication components configured to communicate with the host system computer;

calculate a proportional representation ratio as a percentage of the vehicle population density;

transmit, via at least one of a base station and a satellite system, a request for the data over a network, the request including response criteria configured with the proportional representation ratio, the response criteria specifying which vehicles, of the number vehicles, are directed to respond with the data; and

receive the data from the vehicles in the defined region that fall within the proportional representation ratio, and which meet the response criteria.

2. The system of claim 1, wherein the vehicle population density is calculated from population density census data in combination with previously transmitted responses to requests for the data and a number of roads in the defined region.

3. The system of claim 1, wherein the proportional representation ratio is a user-configurable value and is a function of an anticipated volume of vehicles in the defined region at a point in time.

4. The system of claim 1, wherein the network includes at least one of an FM broadcast network and a radio data system protocol-enabled broadcast network, the host system is a telematics service provider, the communications components in the vehicles are implemented as telematics devices, and the response criteria is used to filter a number of the vehicles for responding to the request;

wherein the data is received from the vehicles through the telematics devices.

5. The system of claim 1, wherein the request for the data includes a portion of a vehicle identification number and the response criteria is configured to use the portion of the vehicle identification number to identify the vehicles from which the data is received.

6. The system of claim 1, wherein the logic is further configured to:

communicate, over the network, with a non-vehicle support device in the defined region, the non-vehicle support device including a camera and a weather antenna; and

receive data indicating an occurrence of a condition, the condition including weather conditions and at least one of a traffic accident and road construction;

wherein the request for the data is transmitted upon the occurrence of the condition detected in the defined region.

7. The system of claim 1, wherein the data subject to the request includes vehicle speed and at least one of:

temperature;

vehicle volume;

vehicle occupancy;

windshield wiper usage;

radio usage;

lane occupancy;

toll collection information;

freight tracking information;

weather conditions; and

roadway conditions.

8. The system of claim 1, wherein the response criteria includes a vehicle type, and the request for the data directs only those vehicles having the vehicle type to respond.

9. The system of claim 1, wherein the logic is further configured to:

provide to subscribers, via a website, access to the data received from the vehicles.

10. The system of claim 1, wherein the logic is further configured to:

communicate, over the network, with a non-vehicle support device in the defined region;

receive at least one of lane occupancy data and toll collection data from the non-vehicle support device; and

combine the data from the non-vehicle support device with the data received from the vehicles to determine events and conditions.

11. A method for data acquisition from a sampling of vehicle sensors, comprising:

identifying, via a host system computer, a vehicle population density representing a number of vehicles in a defined region, each of the vehicles corresponding to the vehicle population density having communication components configured to communicate with the host system computer;

calculating a proportional representation ratio as a percentage of the vehicle population density;

transmitting, via at least one of a base station and a satellite system, a request for data over a network, the request including response criteria configured with the proportional representation ratio, the response criteria specifying which vehicles, of the number of vehicles, are directed to respond with the data; and

receiving the data from the vehicles in the defined region that fall within the proportional representation ratio, and which meet the response criteria.

12. The method of claim 11, wherein the vehicle population density is calculated from population density census data in combination with previously transmitted responses to requests for the data, and a number of roads in the defined region.

13. The method of claim 11, wherein the proportional representation ratio is a user-configurable value and is a function of an anticipated volume of vehicles in the defined region at a point in time.

14. The method of claim 11, wherein the network is at least one of an FM broadcast network and a radio data system protocol-enabled broadcast network, and the response criteria is used to filter a number of the vehicles for responding to the request.

15. The method of claim 11, wherein the request for the data includes a portion of a vehicle identification number and the response criteria is configured to use the portion of the vehicle identification number to identify the vehicles from which the data is received.

16. The method of claim 11, further comprising:

communicating, over the network, with a non-vehicle support device in the defined region, the non-vehicle support device including a camera and a weather antenna; and

receiving data indicating an occurrence of a condition, the condition including weather conditions and at least one of a traffic accident and road construction;

wherein the request for the data is transmitted upon the occurrence of the condition detected in the defined region.

17. The method of claim 11, wherein the data subject to the request includes vehicle speed and at least one of:

temperature;

vehicle volume;

vehicle occupancy;

windshield wiper usage;

radio usage;

lane occupancy;
