Abstract
A digital speed control system including a processor performing arithmetical and logic operations in response to command inputs from the operator to maintain the present vehicle speed, to accelerate at a substantially constant rate to a new cruising speed or to a previously established cruising speed is disclosed. Certain processor operations are phased to speed sensor pulses to permit rate of change of speed computations to be performed with minimum hardware.
