Anti-theft system with remote controlled verification of arming
First Claim
1. A remote controlled anti-theft system for a transportation vehicle providing on-demand audible verification of anti-theft system operation, comprising:
- a portable transmitter transmitting a lock code in response to a manual activation;
door lock actuators for locking doors of said transportation vehicle in response to a lock command signal;
door position sensors associated with said doors, each generating a respective door-closed signal when a respective one of said doors is closed;
a sound transducer producing an audible sound output in response to an energizing signal; and
a vehicle-mounted control module responsive to a first occurrence of said lock code to
1) generate said lock command signal which is sent to said door lock actuators and
2) enter an armed state of said anti-theft system if each of said door position sensors produces a door-closed signal, said control module further being responsive to a second occurrence of said lock code received within a predetermined time of said first occurrence of said lock code to generate a first energizing signal to produce a first audible sound output verifying that said armed state has been entered if said lock command has been sent and each of said door position sensors produces a door-closed signal or to generate a second energizing signal to produce a second audible sound output verifying that said armed state has not been entered if at least one of said door position sensors fails to produce a door-closed signal, said control module not producing any energizing signal absent said second occurrence of said lock code regardless of whether said armed state has been entered.

Abstract
A remote controlled anti-theft system for transportation vehicles allows the user to easily determine at will if a faulty door position sensor or an open door will inhibit proper operation of the anti-theft system by pressing the lock button on the remote transmitter in a predetermined sequence. A first lock code from the remote transmitter initiates a locking and arming sequence of the anti-theft system. A second lock code received within a predetermined time of the first lock code causes an audible verification to be produced identifying whether the anti-theft system is successfully arming or whether a door ajar or faulty door sensor is preventing the anti-theft system from arming.

4. A method of operating a remote controlled anti-theft system for a transportation vehicle comprising the steps of:
-
transmitting a first occurrence of a lock code from a portable transmitter; locking at least one door of said transportation vehicle in response to said first occurrence of said lock code; sensing the open/closed position of said door; entering an armed state of said anti-theft system in response to said first occurrence of said lock code if said door is sensed to be in a closed position; if a second occurrence of said lock code is transmitted within a predetermined time of said first occurrence of said lock code, then either
1) producing a first audible sound output to verify if said armed state has been entered, or
2) producing a second audible sound output to verify if said armed state has not been entered; andwithholding any production of an audible sound output absent said second occurrence of said lock code, whereby no verification is produced concerning said armed or unarmed state of said anti-theft system.
