Abstract

A vehicle security system 10 having a “panic” and/or “alarm tripping” feature which is adapted to allow the activation of a siren/horn/visual indicator in a pseudo-random or “human-like” manner. The system may comprise a portable system to protect an individual or non-automotive object.

Claims

1. A vehicle security system comprising:

an audible indicator; and

a controller having a memory unit containing data derived from experimentation with at least one human subject, said data corresponding to previously generated horn activation signals which have been generated by several individuals and which have been previously probabilistically analyzed and said controller being effective to selectively activate said audible indicator by use of said data, thereby causing said audible indicator to generate a signal.

2. The vehicle security system of claim 1 wherein said audible indicator comprises a siren.

3. The vehicle security system of claim 1 wherein said audible indicator comprises a horn.

4. The vehicle security system of claim 1 wherein said data comprises a plurality of time periods during which said audible indicator is activated and deactivated.

5. The vehicle security system of claim 1 further comprising:

a remote transmitter which selectively generates a command signal; and

wherein said controller is further effective to receive said command signal and to activate said audible indicator in response to said receipt of said command signal.

6. The vehicle security system of claim 1 wherein said data is stored within at least one look-up table held within said memory unit.
