Abstract

An integrated security door lock system which combines a vehicle security system with a remote controlled engine starting system so as to start a vehicle'"'"'s engine, air conditioning; and to start an engine at a preset time or temperature and the alarm system of a vehicle by way of a remote control transmitter.

Claims

1. An integrated security door lock system comprising:

a microprocessor including software;

an alarm unit;

a remote-control engine ignition unit including a relay;

an ignition device;

and an engine started by an engine starter;

and wherein the microprocessor is coupled to the remote-control engine ignition unit;

and wherein the alarm unit is coupled to the remote-control engine ignition unit by only an output wire.

2. The improvement according to claim 1, wherein the relay delays a detecting function of the alarm unit.

3. The improvement according to claim 1, wherein the door lock system keeps doors locked when the engine comes to a stop.

4. A method of operating a vehicle engine starting and security system including a software-controlled microprocessor controlling an engine starter and an anti-theft alarm;

the method comprising;

starting a first time interval when a remote signal is received by the security system;

setting the anti-theft system to a bypass mode only if an ignition switch is turned during the first interval; and

setting the anti-theft system out of bypass mode when the ignition switch is turned off;

wherein the anti-theft alarm includes first sensors responsive to engine running conditions and second sensors responsive to break-in conditions, and wherein only the engine running conditions are bypassed.

5. The method according to claim 4, wherein the first time interval is approximately 1.5 seconds long.

6. An integrated security door lock system comprising:

a microprocessor including software;

an alarm unit;

a remote-control engine ignition unit including a relay;

an ignition device;

and an engine started by an engine starter;

and wherein the microprocessor is coupled to the remote-control engine ignition unit;

and wherein the alarm unit is coupled to the remote-control engine ignition unit by only an output wire;

the remote-control engine ignition unit and the alarm are connected to the ignition device; and

the ignition device includes an output terminal coupled to the engine starter;

wherein the relay delays a detecting function of the alarm unit;

wherein the door lock system keeps doors locked when the engine comes to a stop.
