Abstract
To prevent hunting in an automatic vehicle speed maintenance circuit having a closed control loop, the control element is so arranged that the controller has not only proportional, but additionally derivative control characteristics to increase the response speed while permitting loop amplification which is necessary in view of the response delay characteristic of the controlled element, namely the vehicle itself.
