Abstract

A vehicle disablement device disables a vehicle if it is determined that the vehicle disablement device is being tampered with. A signal is periodically sent from a tamper transmitter to a tamper receiver. A tamper transmitter determines whether the vehicle is being it is being tampered with. The periodic sending of the signal is inhibited if it is determined that the vehicle is being tampered with. The vehicle is disabled if the periodic sending of the signal is inhibited.

Claims

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

a vehicle disablement device, wherein the vehicle disablement device disables the critical system of the vehicle if a payment is not made on the vehicle prior to a payment due date, wherein disablement of the critical system prevents operation of the vehicle;

a tamper transmitter, wherein the tamper transmitter periodically transmits a signal; and

a tamper receiver, wherein the tamper receiver disables a critical system when a signal is not received from the tamper transmitter for a predetermined period of time.

2. The system of claim 1, wherein the tamper transmitter inhibits transmission of the signal when tampering with the vehicle is detected.

3. The system of claim 2, wherein the tamper transmitter detects the tampering.

4. The system of claim 3, wherein the tampering detected by the tamper transmitter is tampering with the vehicle disablement device.

5. The system of claim 1, wherein the critical system disabled by the vehicle disablement device and the critical system disabled by the tamper receiver are different critical systems.

6. The system of claim 5, wherein the critical system disabled by the vehicle disablement device is a starter circuit of the vehicle and the critical system disabled by the tamper receiver is a gas line of the vehicle.

7. The system of claim 1, wherein the vehicle is a motor vehicle.

8. The system of claim 1, wherein the tamper transmitter and the tamper receiver communicate with each other through a hard wired connection.

9. The system of claim 1, wherein the tamper transmitter and the tamper receiver communicate with each through a wireless connection.

10. The system of claim 1, wherein the tamper transmitter is a component of the vehicle disablement device.

11. The system of claim 1, wherein the tamper transmitter is a separate component from the vehicle disablement device, and the tamper transmitter interfaces with the vehicle disablement device.

12. The system of claim 1, wherein the vehicle disablement device further comprises:

red, yellow and green lights which illuminate to indicate whether a payment for the vehicle is due.

13. A method for disabling a vehicle comprising the steps of:

periodically sending a signal from a tamper transmitter to a tamper receiver;

determining, by a tamper transmitter, whether the vehicle is being it is being tampered with;

inhibiting the periodic sending of the signal if it is determined that the vehicle is being tampered with; and

disabling the vehicle if the periodic sending of the signal is inhibited.

14. The method of claim 13, wherein the disabling step comprises the step of:

determining, by the tamper receiver, whether a predetermined amount of time has passed since the last periodic signal has been received; and

disabling, by the tamper receiver, a critical system of the vehicle if it is determined that the predetermined amount of time has passed since the last periodic signal has been received.

15. The method of claim 14, wherein the step of disabling a critical system further comprises the step of:

interrupting power to a fuel pump of the vehicle.

16. The method of claim 14, further comprising the steps of:

determining whether a code has been entered into a vehicle disablement device prior to a due date; and

disabling, by the vehicle disablement device, a critical system of the vehicle if a code has not been entered prior to the due date, wherein the critical system disabled by tamper receiver and the critical system disabled by the vehicle disablement device are different systems.

17. The method of claim 13, wherein the tamper transmitter interfaces with a vehicle disablement device, and whether the vehicle is being tampered with is detected by detecting that a power wire of the vehicle disablement device has been severed, detecting that a ground wire of the vehicle disablement device has been severed, detecting whether a starter wire passing through the vehicle disablement device has been cut.
