System and method for disabling a vehicle

1. A system for disabling a vehicle, the system comprising:

an antenna adapted for attachment to the vehicle, the antenna configured to transmit and receive communication transmissions; and

a telematics unit communicatively connected to the antenna, the telematics unit being adapted for attachment to the vehicle and configured to:

communicatively connect to a necessary sub-system of the vehicle,

receive telecommunications from a user through the antenna, and

disable the necessary sub-system in response to receiving an instruction from the user to disable the vehicle,

wherein the instruction from the user to disable the vehicle comprises a temporal criterion specified by the user for disabling the vehicle and wherein the telematics unit is further configured to automatically disable the necessary sub-system when the temporal criterion is satisfied, and

wherein the instruction from the user to disable the vehicle further comprises a geographic restriction specified by the user for disabling the vehicle and wherein the telematics unit is further configured to automatically disable the necessary sub-system when the geographic restriction is exceeded by the vehicle.

2. The system of claim 1 , wherein the telematics unit is further configured to disable the necessary sub-system by inhibiting the necessary sub-system from functioning when attempts are made by a person to start the vehicle.

3. The system of claim 1 , wherein the telematics unit is further configured to receive the instruction from the user through an Interactive Voice Response interface.

4. The system of claim 1 , wherein the necessary sub-system is a powertrain controller module.

5. The system of claim 1 , wherein the temporal criterion comprises one of a time restriction, a data restriction and a restriction on total hours of engine operation during a specified time period.

6. The system of claim 1 , wherein the telematics unit is further configured to require satisfaction of a security measure before the telematics unit will disable the necessary sub-system.

7. A system for disabling a vehicle, the system comprising:

a call center;

an antenna adapted for attachment to the vehicle, the antenna configured to transmit and receive communication transmissions to and from the call center; and

a telematics unit communicatively connected to the antenna, the telematics unit being adapted for attachment to the vehicle and configured to:

communicatively connect to a necessary sub-system of the vehicle,

receive telecommunications from a user through the antenna, and

disable the necessary sub-system in response to receiving an instruction from the user to disable the vehicle,

wherein the instruction from the user to disable the vehicle comprises a temporal criterion specified by the user for disabling the vehicle and wherein the telematics unit is further configured to automatically disable the necessary sub-system when the temporal criterion is satisfied, and

wherein the temporal criterion comprises one of a time restriction, a date restriction and a restriction on total hours of engine operation during a specified time period, and

wherein the instruction from the user to disable the vehicle further comprises a geographic restriction specified by the user for disabling the vehicle and wherein the telematics unit is further configured to automatically disable the necessary sub-system when the geographic restriction is exceeded by the vehicle.

8. The system of claim 7 , wherein the telematics unit is further configured to disable the necessary sub-system by inhibiting the necessary sub-system from functioning when attempts are made by a person to start the vehicle.

9. The system of claim 7 , wherein the telematics unit is further configured to receive the instruction from the user through an Interactive Voice Response interface.

10. The system of claim 7 , wherein the call center is configured to receive the instruction to disable the vehicle from the user and to communicate the instruction to disable the vehicle to the telematics unit.

11. The system of claim 10 , the system further comprising an Internet website communicatively connected to the call center, the Internet website being configured to receive the instruction to disable the vehicle from the user and to transmit the instruction to disable the vehicle to the call center.

12. The system of claim 7 , wherein the necessary sub-system is a powertrain controller module.

13. The system of claim 7 , wherein the telematics unit is further configured to require satisfaction of a security measure before it can disable the necessary sub-system.

14. The system of claim 13 , wherein the security measure comprises requiring one of a PIN and a password.

15. A method for disabling a vehicle that requires a necessary sub-system for operation, the method comprising the steps of:

receiving at a telematics unit an instruction originating from a user to disable the vehicle, the instruction comprising a temporal criterion specified by the user, the temporal criterion comprising one of a time restriction, a date restriction and a restriction on total hours of engine operation during a specified time period, and the instruction further comprising a geographic restriction specified by the user for disabling the vehicle and wherein the telematics unit is further configured to automatically disable the necessary sub-system when the geographic restriction is exceeded by the vehicle; and

disabling the necessary sub-system of the vehicle when the criterion is satisfied.

16. The method of claim 15 , the method further comprising the steps of:

monitoring for an occurrence of a condition that satisfies the criterion; and

disabling the necessary sub-system when the condition is present.

17. The method of claim 16 further comprising the steps of:

monitoring for a cessation of the condition that satisfies the criterion; and

enabling the necessary sub-system when the condition has ceased.
