Abstract:
A car jacking prevention system comprising:a programmable control unit in controlling connection with:a multi-timer unit having an output in connection with a mono-timer, an on board audio warning output system, and a manual disarm switch; anda mono-timer having an activation output in electrical connection with each of the activation inputs of an engine cut-off mechanism, a hood lock assembly, an audible alarm system, and a visual alarm system;the car jacking prevention system further including:a manual activation input in connection with a manual activation switch that may be hidden within a vehicle passenger compartment at a location known only to regular drivers of the vehicle, anda radio signal switch having a receiving antenna for receiving a radio transmitted activation signal and a radio switch activation output in connection with a radio activation input of the control unit;the radio signal switch being responsive to receipt of the radio transmitted activation signal by transmitting a system activation signal to the radio activation input of the control unit;the manual activation switch generating a system activation signal to the control unit when depressed by a user;the control unit being programmed to trigger the multi-timer circuit upon receipt of a system activation signal;when triggered, the multi-timer circuit activating the on board audio warning system to audibly warn a driver of the vehicle that a car jacking prevention system has been enabled and that within a time period vehicle disabling and attention attracting events will be occurring, triggering the mono-timer, and activating the manual disarm switch which when depressed by the user before the mono-timer times out resets the control unit and thereby the car jacking prevention system;the mono-timer generating a control signal at its activation output upon timing out to simultaneously activate the engine cut-off mechanism, the hood lock assembly, the audible alarm system, and the visual alarm system.
