Abstract
A system for automatically controlling driving speed includes a fixed speed driving device for keeping the driving speed at a predetermined speed and a control device for maintaining an optimum interval between the vehicle and the vehicle driving ahead. A hold circuit for holding the optimum driving speed, based on the distance from the vehicle driving ahead, is actuated by a circuit for detecting curves in the road, whereby the hold circuit maintains the driving speed of the vehicle as it rounds a curve at the optimum driving speed determined for the vehicle before it entered the curve.
