Vehicle data communications bus disrupter and associated methods
First Claim
1. A vehicle security system for a vehicle comprising an engine, at least one vehicle engine device, and a vehicle data communications bus carrying communications for the at least one vehicle engine device, the vehicle security system comprising:
- at least one vehicle security sensor;
a vehicle data communications bus disrupter for disrupting communications on the vehicle data communications bus for the at least one vehicle engine device; and
a security controller for selectively operating said vehicle data communications bus disrupter based upon said at least one vehicle security sensor to disable the vehicle engine.

Abstract
A vehicle security system may disrupt communications on a vehicle data communications bus, such as to prevent starting of the vehicle engine. The vehicle security system may include at least one vehicle security sensor, a vehicle data communications bus disrupter for disrupting communications on the vehicle data communications bus, and a security controller for selectively operating the vehicle data communications bus disrupter. The disrupter may be operated based upon the at least one vehicle security sensor to thereby disable the vehicle engine. The disrupter may alternately be operated based on a signal from a monitoring station that receives position information from the vehicle.
