Abstract

A pre-warn vehicle security device is for a vehicle including a data communications bus, an alert indicator, and an alarm controller. The alarm controller may interface with the data communications bus and, when in an armed mode, may cause the alert indicator to generate an alarm indication responsive to a high security threat level. More particularly, the pre-warn vehicle security device may include a pre-warn vehicle security sensor for sensing a threat level lower than the high security threat level and a pre-warn emulator. Responsive to the pre-warn vehicle security sensor, the pre-warn emulator may generate at least one signal on the data communications bus so that the alarm controller causes the alert indicator to generate an emulated pre-warn indication different from the alarm indication.

Claims

1. A pre-warn vehicle security device for a vehicle comprising a data communications bus extending throughout the vehicle, the data communications bus carrying data and address information thereover, an alert indicator, and an alarm controller interfacing with the data communications bus extending throughout the vehicle and carrying data and address information and when in an armed mode causing the alert indicator to generate an alarm indication responsive to a sensed high security threat level condition, the pre-warn vehicle security device comprising:

a pre-warn vehicle security sensor for sensing a security threat level condition lower than the sensed high security threat level condition; and

a pre-warn emulator for generating at least one signal on the vehicle data communications bus extending throughout the vehicle and carrying data and address information responsive to said pre-warn vehicle security sensor so that the alarm controller causes the alert indicator to generate an emulated pre-warn indication different from the alarm indication;

said pre-warn emulator, responsive to said pre-warn vehicle security sensor sensing the low security threat level condition, sequentially generating, on the data communications bus extending throughout the vehicle and carrying data and address information, a high security threat level signal corresponding to the sensed high security threat level condition and a duration shortening signal for the alert indicator for generating a shortened alarm indication.

2. The pre-warn vehicle security device of claim 1 wherein said pre-warn emulator sequentially generates the high security threat level signal and the duration shortening signal less than about five seconds apart.

3. The pre-warn vehicle security device of claim 1 wherein said pre-warn emulator, responsive to said pre-warn vehicle security sensor, generates a plurality of armed mode signals on the data communications bus extending throughout the vehicle and carrying data and address information.

4. The pre-warn vehicle security device of claim 1 wherein the pre-warn indication has a shorter duration than the alarm indication.

5. The pre-warn vehicle security device of claim 1 wherein the pre-warn indication is audible and has a lesser volume than the alarm indication.
