Abstract

A vehicle security system that includes a knock detection means such as a microphone configured to detect knocking on the vehicle such as knocking on a window of the vehicle. The system includes a controller configured to receive a signal from the knock detection means and unlock a door of the vehicle if the signal corresponds to a predetermined pattern.

Claims

1. A vehicle security system comprising:

a knock detection means configured to detect knocking on the vehicle; and

a controller configured to receive a signal from the knock detection means and unlock a door of the vehicle if the signal corresponds to a predetermined pattern.

2. The system in accordance with claim 1, wherein the knock detection means is a microphone.

3. The system in accordance with claim 1, wherein the controller is further configured

to activate a light if knocking is detected.

4. The system in accordance with claim 1, wherein the controller is further configured

to detect a door handle actuation, and monitor the signal for an activation interval if a door handle actuation is detected.

5. The system in accordance with claim 4, wherein the controller is further configured

to activate a light if the door handle actuation is detected.

6. The system in accordance with claim 1, wherein the predetermined pattern comprises

a first number of knocks followed by a second number of knocks, wherein the second number of knocks begins following a pause interval after the first number of knocks.

7. The system in accordance with claim 6, wherein the end of the pause interval is

indicated by the controller activating a light.

8. The system in accordance with claim 1, wherein the predetermined pattern comprises

a plurality of knocks, wherein each subsequent knock follows the previous knock by a distinct delay interval.

9. The system in accordance with claim 1, wherein the controller is further configured

to be operated into a learn mode whereby the predetermined pattern is saved in the controller.
