Abstract

A cruise control system for keeping substantially constant distance to a preceding motorcar by a position servo unit which controls a fuel supply of a car, including a pacemaker which produces a difference between an imaginary pace value which is proportional to the car velocity at an instance when a driver judges that a stable constant distance to the preceding car is attained and an actual pace value, the difference being fed to the position servo unit which functions to reduce the difference to keep a constant set distance value to the car in front. The invention modifies the difference directly or indirectly when the driver judges that the velocity of his car deviates from the set distance value which has been set previously.
