Abstract

A wireless tracking device located in a vehicle, the device including a positioning system to periodically determine a location of the device, a processor connected to the positioning system to receive a vehicle sensor input indicating the vehicle status, a scanner to scan for an available wireless area network access point, and a wireless radio connected to the processor to transmit data to the available wireless area network access point.

Claims

1. A method of monitoring a vehicle, the method comprising:

from the vehicle, periodically determining a vehicle location;

scanning to locate an available wireless data network access point; and

transmitting a status of the vehicle through the located access point to an endpoint receiver.

2. The method according to claim 1 wherein the current vehicle location is determined according to a global positioning system (GPS) signal.

3. The method according to claim 1 wherein the wireless data network access point is an IEEE 802.16 (WiMAX) access point.

4. The method according to claim 1 further comprising:

determining that the vehicle is being used by an unauthorized operator; and

transmitting an alert message.

5. The method according to claim 4 including shutting down operation of the vehicle in response to determining that the vehicle is being used by an unauthorized operator.

6. The method according to claim 1 including providing an access code or login to the wireless data network access point to enable access to the wireless data network.

7. The method according to claim 1 where the wireless data network access point is located using passive scanning.

8. The method according to claim 7 wherein the transmitting of the status information includes transmitting at least one of location data and vehicle sensor data.

9. The method according to claim 1 where the wireless data network access point is located using active scanning.

10. The method of claim 1, wherein the transmitting the status of the vehicle includes transmitting logged vehicle data corresponding to the path of the vehicle over a period of time.

11. A wireless tracking device locatable in a vehicle, the wireless tracking device comprising:

a positioning system configured to periodically determine a location of the device;

a processor connected to the positioning system and configured to receive vehicle sensor input indicating a vehicle status;

a scanner configured to scan for an available wireless area network access point;

and

a wireless radio connected to the processor and configured to transmit data including at least one of location data and vehicle sensor data to the available wireless area network access point.

12. The wireless tracking device according to claim 11 wherein the processor is configured to receive the vehicle sensor data and generate vehicle condition data for transmission by the wireless radio to the wireless area network access point.

13. The wireless tracking device according to claim 12 wherein the vehicle sensor input includes at least one of vehicle speed, vehicle direction, car alarms signal, or key ignition detection signal.

14. The wireless tracking device according to claim 12 wherein the scanner is configured to scan at least one of the available wireless area network access points including a WLAN or WMAN configured to IEEE standards 802.11 or 802.16 (WiMAX).

15. The wireless tracking device according to claim 14 wherein the wireless radio passively scans for the available wireless area network access.

16. The wireless tracking device of claim 11, further comprising the wireless radio to transmit logged data corresponding to the path of the vehicle over a period of time.

17. A vehicle monitoring system comprising:

a positioning system configured to periodically determine a location of a vehicle;

a sensor configured to receive sensor data including vehicle status data;

a microcontroller configured to receive the sensor data from the sensor, to determine a vehicle condition and to receive vehicle location data from the positioning system, wherein the microcontroller is further configured to shut down vehicle operation when the determined vehicle condition corresponds to the vehicle being operated by an unauthorized operator; and

a wireless transmitter communicatively coupled to the microcontroller and configured to scan for and connect to an available wireless data network remote access point, and when connected, to transmit the vehicle condition and the vehicle location data to the remote data network access point.

18. The vehicle monitoring system according to claim 17 including a configuration device that provides at least one selectable mode of operation.

19. The vehicle monitoring system according to claim 18 wherein the at least one selectable mode of operation is selected from modes including passive scanning, active scanning, data transmission standard, or account management of the remote data network access point.

20. The vehicle monitoring system according to claim 17 wherein the wireless transmitter is further configured to transmit data to an endpoint, wherein the endpoint includes at least one of a computer, a website, a short message service (SMS) or an e-mail account.
