Electronic speed control for vehicle - has impulse generator delivering signals to counter with flip=flop reset forming independent control

摘要

The vehicle speed is converted into signal pulses by an impulse generator to feed a counter. When the required speed is reached, the count is stored permanently by comparing the output of the counter, through a resistor array with the output of the signal generator. The counter is controlled by a flip-flop which automatically resets the counter when the ignition is switched off. The control operates independently to variations in the resistors and is unaffected by capacitance drain etc. in the storage circuit.
