Abstract
A speed selector (24, 25, 40) actuates a computer (32, 35, 38, 39) to calculate optimum engine speed, speed-change rate and gear ratio for achieving a selected speed of a motor vehicle (18). An actuator (36) then accomplishes throttling of an engine (19) with a throttling means (20) and gear changes of a transmission (21) as necessary to achieve the selected vehicle speed with least-possible fuel consumption and exhaust smog. When a desired change in speed is made, it is maintained in a cruise-control mode with optimized rates of change of throttling and gear-shifting for necessary changes in engine speed for varying terrain and driving conditions.
