Abstract

An automated system for immobilizing a vehicle and method therefore typically employed in a motor vehicle for disabling the throttle and deploying the brake and clutch control systems after a theft of the vehicle has occurred is disclosed. The invention includes a plurality of devices for monitoring a plurality of parameters of the vehicle and for generating the triggering signal. A central control microprocessor is employed for receiving and analyzing the plurality of parameters and for detecting the triggering signal. A throttle adjustable range actuator module is utilized for disabling the throttle of the vehicle upon detection of the triggering signal. Finally, a brake adjustable range actuator module is included for deploying the brakes to stop the vehicle. Additionally, a clutch adjustable range actuator module is included for deploying a manual clutch, if the vehicle is fitted with one, for preventing the wheels of the vehicle from being driven. The plurality of vehicle parameters monitored include the vehicle speed, status of an audio power supply and vehicle sound system, state of external triggering devices, instructions imputed from a reset keypad, microprocessor control data received across a data link, and the state of a plurality of adjustable range actuator modules.

Claims

1. An automated system for immobilizing a vehicle comprising:

first means for monitoring a plurality of parameters of said vehicle and for generating a triggering signal;

a central control microprocessor for receiving said plurality of parameters and for detecting said triggering signal;

a throttle adjustable range actuator module for disabling an accelerator pedal of said vehicle upon detection of said triggering signal from said microprocessor, said throttle actuator module including an electrically operated solenoid for positioning a vertically movable pulley to control the tension in an accelerator cable, wherein reduced tension in said accelerator cable disables said accelerator pedal without disabling the engine of said vehicle; and

A brake adjustable range actuator module for deploying a braking system of said vehicle upon detection of said triggering signal from said microprocessor, said brake actuator module including an electrically operated motor and a plurality of gears for positioning a threaded sliding bolt along a rotatable threaded shaft to control the tension in a wire cable attached to a brake pedal of said vehicle, wherein increased tension in said wire cable depresses said brake pedal and deploys said braking system to stop said vehicle.

2. The automated system of claim 1 wherein said first means monitors a speedometer of said vehicle for indicating the speed of said vehicle.

3. The automated system of claim 1 wherein said first means monitors incoming signals from an external triggering device.

4. The automated system of claim 1 wherein said first means monitors a reset keypad/receiver for imputing instructions into said central control microprocessor.

5. The automated system of claim 1 further including an audio control relay for disconnecting a vehicle sound system from a vehicle audio power supple for muting said vehicle sound system to enable the audio broadcast of a plurality of audio and sensory warnings from a warning systems controller.

6. The automated system of claim 1 further including a clutch adjustable range actuator module for disengaging the clutch of said vehicle upon detection of said triggering signal from said microprocessor, said clutch actuator module including an electrically operated motor and a plurality of gears for positioning a threaded sliding bolt along a rotatable threaded shaft to control the tension in a wire cable attached to a clutch pedal of said vehicle, wherein increased tension in said wire cable depresses said clutch pedal for deploying the clutch of said vehicle.

7. An automated system for immobilizing a vehicle comprising:

first means for monitoring a plurality of parameters of said vehicle and for generating a triggering signal;

a microprocessor for receiving said plurality of parameters and for detecting said triggering signal;

a throttle adjustable range actuator module for disabling an accelerator pedal of said vehicle upon detection of said triggering signal from said microprocessor, said throttle actuator module including an electrically operated solenoid for positioning a vertically movable pulley to control the tension in an accelerator cable, wherein reduced tension in said accelerator cable disables said accelerator Pedal without disabling the engine of said vehicle;

a brake adjustable range actuator module for deploying a braking system of said vehicle upon detection of said triggering signal from said microprocessor, said brake actuator module including an electrically operated motor and a plurality of gears for positioning a threaded sliding bolt along a rotatable threaded shaft to control the tension in a wire cable attached to a brake pedal of said vehicle, wherein increased tension in said wire cable depresses said brake pedal and deploys said braking system to stop said vehicle; and

a plurality of sensor switches Positioned within said brake actuator module for limiting the travel of said threaded sliding bolt along said rotatable threaded shaft.

8. A method for automatically immobilizing a vehicle, said method comprising the steps of:

monitoring a plurality of parameters of said vehicle and generating a triggering signal;

receiving and detecting said triggering signal at a central control microprocessor in said vehicle;

muting a sound system located within said vehicle;

activating a warning systems controller within said vehicle for enabling the broadcast of a plurality of audio and sensory warning messages;

disabling an accelerator pedal of said vehicle by positioning a vertically movable pulley with an electrically operated solenoid for controlling the tension in an accelerator cable; and

deploying the brakes of said vehicle to stop said vehicle by positioning a threaded sliding bolt along a rotatable threaded shaft using a motor and a plurality of gears for controlling the tension in a wire cable attached to a brake pedal.
