Computerized control of automobile speed
First Claim
1. A method comprised of the following steps for computerized control and continuous variation of speed of a motor vehicle:
- ascertaining the motor-vehicle'"'"'s existing speed factor;
selecting an intended speed for the motor vehicle on a continuous basis by a driver-operated selector;
determining difference-of the intended speed from the motor-vehicle'"'"'s existing speed factor;
calculating brake horsepower required of a vehicle engine to implement an optimal speed change and change rate to attain the intended speed of the motor vehicle with at least one predetermined gear ratio of a transmission positioned intermediate the vehicle engine and a vehicle drive shaft;
calculating increase in brake horsepower required of a vehicle engine to implement the optimal speed change and change rate to attain the intended speed from the existing speed factor with at least one predetermined gear ratio of the transmission;
calculating rate of increase in fuel added to the vehicle engine to achieve rotational speed and related brake horsepower of the vehicle engine in order to attain the intended speed from the existing speed factor with optimum efficiency and minimization of exhaust smog of the vehicle engine; and
adding fuel to the vehicle engine at an increased rate calculated to attain the intended speed from the existing speed factor with select efficiency and minimization of exhaust smog of the vehicle engine.

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.
