Abstract

A remotely operable vehicle disabling system for terminating operation of a vehicle. The system has a remotely operable transmit unit for transmitting a command shutdown message to a command-receiver vehicle unit in a vehicle. The vehicle unit is in communication with at least one operational component and capable of shutting down that component to thereby terminate vehicle operation. The transmit unit can initially transmit a query message prior to the shutdown message to confirm vehicle identity or to confirm the presence of the vehicle disabling system. Correspondingly, the vehicle unit is capable of receiving both the query message and the shutdown message and of responding to the query message, with all such communication activities preferably being encoded with a continuously changing key. The disabling system provides a safe and efficient manner for law enforcement personnel to apprehend criminals attempting to escape in vehicles.

Claims

1. A remotely operable vehicle disabling system for terminating operation of a vehicle, the system comprising:

a) a remotely operable transmit unit for transmitting a query message and a shutdown message and for receiving a response to the query message;

b) a transmitter hand unit for remotely activating the transmit unit; and

c) a vehicle unit capable of receiving the query message and the shutdown message and for providing a query message response, with said vehicle unit being in communication with at least one operational component of the vehicle and capable of shutting down said component upon receipt of a shutdown message from the transmit unit to thereby terminate vehicle operation.

2. A remotely operable vehicle disabling system as claimed in claim 1 wherein the transmit unit is an infrared transmitter transmitting an infrared laser beam bearing the query message and the shutdown message.

3. A remotely operable vehicle disabling system as claimed in claim 1 wherein the query message, shutdown message and query message response are encoded with a continuously changing key determined by time of day and an algorithm common to the query message, shutdown message and query message response.

4. A remotely operable vehicle disabling system as claimed in claim 1 wherein the remotely operable transmit unit is mounted within a law enforcement vehicle.

5. A remotely operable vehicle disabling system as claimed in claim 1 wherein the remotely operable transmit unit is handheld.

6. A remotely operable vehicle disabling system as claimed in claim 1 wherein the operational component is a fuel flow termination device.

7. A remotely operable vehicle disabling system as claimed in claim 6 wherein the fuel flow termination device is a closable valve disposed in a fuel line leading from a fuel source to an engine, said valve being closable by the vehicle unit upon receipt of a shutdown message from the transmit unit to thereby close the valve.

8. A remotely operable vehicle disabling system as claimed in claim 1 wherein the operational component is an electrical power termination device for terminating electrical operating power leading from a power source to an engine.

9. A remotely operable vehicle disabling system as claimed in claim 8 wherein the electrical power termination device is a power disconnection switch situated between the power source and a power distributor for the engine, said switch being operable by the vehicle unit upon receipt of a shutdown message from the transmit unit to thereby shut down electrical power.

10. A remotely operable vehicle disabling system as claimed in claim 1 additionally comprising a visually observable tamper-evident indicator in communication with the operational component and disposed at an external site of the vehicle whereby tampering with the operational component activates the indicator.

11. A remotely operable vehicle disabling system as claimed in claim 10 wherein the visually observable tamper-evident indicator is a light disposed at an external site of the vehicle.

12. A remotely operable vehicle disabling system as claimed in claim 1 wherein the query message and the shutdown message of the transmit unit are encoded and the query message response of the vehicle unit is encoded with a code complimentarily to the code of the query message.

13. A remotely operable vehicle disabling system as claimed in claim 12 wherein the query message, shutdown message and query message response are encoded with a continuously changing key determined by time of day and an algorithm common to the query message, shutdown message and query message response.

14. A remotely operable vehicle disabling system for terminating operation of a vehicle, the system comprising:

a) a remotely operable transmit unit for transmitting a shutdown message;

b) a transmitter hand unit for remotely activating the transmit unit;

c) a vehicle unit capable of receiving the shutdown message, with said vehicle unit being in communication with at least one operational component of the vehicle and capable of shutting down said component upon receipt of the shutdown message from the transmit unit to thereby terminate vehicle operation; and

d) a visually observable tamper-evident indicator in communication with the operational component and disposed at an external site of the vehicle whereby tampering with the operational component activates the indicator.

15. A remotely operable vehicle disabling system as claimed in claim 14 wherein the transmit unit is an infrared transmitter transmitting an infrared laser beam bearing the shutdown message.

16. A remotely operable vehicle disabling system as claimed in claim 14 wherein the visually observable tamper-evident indicator is a light disposed at an external site of the vehicle.

17. A remotely operable vehicle disabling system as claimed in claim 14 wherein the remotely operable transmit unit is mounted within a law enforcement vehicle.

18. A remotely operable vehicle disabling system as claimed in claim 14 wherein the remotely operable transmit unit is handheld.

19. A remotely operable vehicle disabling system as claimed in claim 14 wherein the operational component is a fuel flow termination device.

20. A remotely operable vehicle disabling system as claimed in claim 19 wherein the fuel flow termination device is a closable valve disposed in a fuel line leading from a fuel source to an engine, said valve being closable by the vehicle unit upon receipt of a shutdown message from the transmit unit to thereby close the valve.

21. A remotely operable vehicle disabling system as claimed in claim 14 wherein the operational component is an electrical power termination device for terminating electrical operating power leading from a power source to an engine.

22. A remotely operable vehicle disabling system as claimed in claim 21 wherein the electrical power termination device is a power disconnection switch situated between the power source and a power distributor for the engine, said switch being operable by the vehicle unit upon receipt of a shutdown message from the transmit unit to thereby shut down electrical power.
