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.
