  • Vehicle speed regulation system
    Patent number: 3952236
    Abstract: A digital tachometer provides a signal proportional to output speed which clocks a multivibrator whose "on" time is selectively set as a function of desired speed. The output is filtered and any deviation from one-half the peak voltage becomes the speed error signal which is pulse width modulated to provide an error signal to the prime mover. Proper selection of multivibrator parameters provides for a plurality of output pulse widths which accommodate sensitive speed regulation over a low speed range.
