Excessive speed and theft deterrent system
First Claim
1. An excessive speed and theft deterrent system for automotive vehicles comprising means for generating a signal having a magnitude which is proportional to the speed of said vehicle, comparator means responsive to said generated speed proportional signal for generating an output signal when the magnitude of said generated speed proportional signal is greater than a preselected voltage level, said preselected voltage level corresponding to a predetermined speed, scaling means for varying the magnitude of said speed proportional signal to thereby vary the speed at which the output of said means for generating a speed proportional signal is equal to said preselected voltage, means responsive to the output signal of said comparator means for generating a pulse train, said pulse train having a predetermined frequency, means for delaying the generation of said pulse train after said comparator means has generated said comparator output signal, means for recording the number of pulses generated by said pulse generating means to thereby indicate to total time in which said vehicle has operated at speeds exceeding said predetermined speed, said comparing means generating a second output signal when the magnitude of said generated speed proportional signal is greater than a second preselected voltage level, said second output signal being generated when the speed of said vehicle approaches said predetermined vehicle speed, and means responsive to said second signal for energizing an indicator when the speed of said vehicle approaches the predetermined vehicle speed level.

Abstract
An excessive speed and theft deterrent system wherein a signal is generated having a magnitude which is proportional to the speed of the vehicle. A comparator generates an output signal when the magnitude of the generated signal is greater than a preselected voltage level. In response to the output signal, a pulse train is generated having a predetermined pulse rate wherein the pulse train is counted to thereby indicate a total time in which the vehicle is operated at speeds exceeding a predetermined speed. The system also includes sounding devices for generating a warning signal when a door or the ignition system is operated without authorization.
