Abstract
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.

Claim 2
Dependent Claim
110 words
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.
Claim 3
Dependent Claim
32 words
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.
Claim 4
Dependent Claim
47 words
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.
Claim 5
Dependent Claim
24 words
A remotely operable vehicle disabling system as claimed in claim 1 wherein the remotely operable transmit unit is mounted within a law enforcement vehicle.
Claim 6
Dependent Claim
19 words
A remotely operable vehicle disabling system as claimed in claim 1 wherein the remotely operable transmit unit is handheld.
Claim 7
Dependent Claim
21 words
