Abstract

A vehicle security apparatus includes a portable transmitter generating at least one discrete coded signal. A receiver mounted in the vehicle in response to the first receipt and recognition of a discrete coded signal from the transmitter arms an anti-theft system in the vehicle security apparatus. The anti-theft system includes a starter interrupt which prevents the starting of the vehicle when the anti-theft system is armed and/or alarms, both visual and/or audible, to indicate an attempted access to the vehicle. The receiver is capable of learning one or more codes associated with specific transmitters. A sensor is mounted on the vehicle to detect attempted access to the vehicle. The receiver, when armed and receiving an output from the sensor, activates the starter interrupt and/or the alarm for a predetermined time. The receiver is optionally capable of automatically operating the vehicle door locks, the vehicle hood latch and trunk latches, as well as the inside vehicle lights automatically during the arming and disarming sequences.

Claims

1. A vehicle security apparatus comprising:

transmitter means carried by a user for transmitting a first discrete coded signal identifying a specific transmitter means;

sensor means mounted on the vehicle for sensing attempted access to the vehicle;

receiver means, mountable in the vehicle, for receiving and recognizing the first discrete coded signal from the transmitter means, the receiver means including;

anti-theft means;

means for learning a first discrete coded signal associated with a specific transmitter means while the first discrete coded signal is being transmitted by the transmitter means and received by the receiver means; and

means for arming the anti-theft means upon the first receipt and recognition of a learned discrete coded signal and for disarming the anti-theft means upon the second receipt and recognition of the learned discrete coded signal.

2. The vehicle security apparatus of claim 1 wherein the transmitter means includes:

means for storing a discrete code.

3. The vehicle security apparatus of claim 2 wherein the storing means comprises:

a plurality of selectively severable electrical conductors connected in parallel to a source of electrical power and forming a discrete binary code when electrical power is applied thereto.

4. The vehicle security apparatus of claim 2 wherein the storing means comprises:

controller means for receiving a code from the transmitter means; and

memory means, responsive to the controller means, for storing the discrete code.

5. The vehicle security apparatus of claim 1 wherein the transmitter means further includes:

a first push button for activating the transmitter means to transmit a first discrete coded signal.

6. The vehicle security apparatus of claim 2 wherein the transmitter means further includes:

means for storing a plurality of discrete codes;

a plurality of push buttons, each associated with one of the plurality of stored discrete codes; and

controller means, responsive to the push buttons, for transmitting the stored discrete code associated with the depressed push button.

7. The vehicle security apparatus of claim 6 wherein the learning means further includes:

means for learning a plurality of discrete coded signals while each discrete coded signal is being transmitted by any transmitter means and received by the receiver means; and

means, responsive to the successive receipt and recognition of each discrete coded signal, for arming and disarming the anti-theft means.

8. The vehicle security apparatus of claim 1 wherein the anti-theft means comprises:

means for inhibiting the starting of the vehicle when armed.

9. The vehicle security apparatus of claim 8 wherein the means for inhibiting starting of the vehicle comprises:

switch means, responsive to the receiver means and connected between the vehicle battery and the vehicle starter, for disconnecting electrical power to the starter of the vehicle when the anti-theft means is armed.

10. The vehicle security apparatus of claim 1 wherein the anti-theft means comprises:

alarm means, responsive to the receiver means and the sensor means, for generating an alarm when an attempted access to the vehicle is sensed by the sensor means while the anti-theft means is armed.

11. The vehicle security apparatus of claim 10 wherein the alarm means is an audible alarm mounted on the vehicle.

12. The vehicle security apparatus of claim 10 wherein the alarm means is a visual alarm mounted on the vehicle.

13. The vehicle security apparatus of claim 12 wherein the visual alarm is a light.

14. The vehicle security apparatus of claim 10 wherein the alarm means comprises audible and visual alarms.

15. The vehicle security apparatus of claim 1 wherein the anti-theft means comprises:

means for inhibiting starting of the vehicle when armed; and

alarm means, responsive to the receiver means, for generating an alarm when an attempted access to the vehicle is sensed by the sensor means and the anti-theft means is armed.

16. The vehicle security apparatus of claim 15 wherein the alarm means comprises audible and visual alarms.
