Abstract

A self-contained safety and security system and method that performs the multiple functions of theft deterrence, battery saving, battery analysis system, accident protection, and telemetry and control data communication for vehicles is disclosed. The present invention is an electronically-based system for a vehicle having an existing power transmission circuit including a battery that can be readily installed and made operational by an individual having no special training using common household tools. The safety and security system requires the installation of no dedicated wiring in the vehicle. Furthermore, the system preferably installs without any cutting or splicing of the wiring in the vehicle's electrical system. A preferred embodiment of the present invention includes an electrical activity sensor coupled to and sensing electrical activity on the direct current power transmission circuit, a motion sensor sensing vibration associated with the vehicle, a battery-disconnect switch electrically interposed in the direct current power transmission circuit; and a controller having inputs to receive signals from the electrical activity and motion sensors and an output to communicate with and control the switch. The electrical activity sensor has an electrical activity sensor output producing an electrical activity output signal functionally related to a voltage detected on the direct current power transmission circuit. Similarly, the motion sensor includes a motion sensor output that is electrically coupled to the input of the controller and produces a motion sensor output signal functionally related to any vibration detected within the vehicle.
