Vehicle cruise control

摘要

An automatic control of speed for a vehicle is based on using speed setting, actual speed, acceleration and the change of the slope of the road to set fuel flow for improved fuel mileage. The proposed system of sensors and a programmed computer automatically manages fuel flow to the engine as the truck moves in gusting winds and through transitions from one slope of the road to another. As the conventional cruise control operates to maintain or change speed according to a speed setting Vs the actual speed, the added control of this invention results in a modification of the signal to fuel flow depending upon what road slope change and acceleration is detected. The result is an improvement in fuel mileage.
