1. An Anti-Collision System for use with a vehicle having a hydraulic fluid braking system comprising:

  • a laser rangefinder mountable upon a front side of the vehicle for generating a first electronic signal;

    a self-speed determining means for generating a second electronic signal;

    a controller for processing the first electronic signal to determine the distance between the vehicle and an obstacle located in front of the vehicle and for processing the second electronic signal to determine the self-speed of the vehicle;

    an alarm means functionally connected to the controller for producing an alarm upon the receipt of an alarm signal from the controller; and

    a braking means functionally connected to the controller for applying a braking force to the vehicle upon the receipt of a braking signal from the controller, the braking means further comprising a solenoid driver responsive to the braking signal, the solenoid driver being coupled to a solenoid, and a piston slidably and sealingly disposed within a sealed fluid reservoir in fluid flow communication with the vehicle'"'"'s hydraulic fluid braking system, the piston being fixedly attached to a shaft, the shaft being spring biased against the sealed fluid reservoir and further comprising a solenoid core, the piston exerting a force upon a hydraulic fluid disposed within the sealed fluid reservoir upon the activation of the solenoid, the hydraulic fluid exerting a hydraulic pressure upon the vehicle'"'"'s hydraulic fluid braking system.
