Abstract

An apparatus for controlling the traveling speed of a motor vehicle with an electric control unit, which unit compares the then present actual traveling speed of a vehicle with a predetermined desired nominal traveling speed and transmits a signal which is dependent on the size of the deviation to a control stage. The control stage comprises an actuator acting on an element, preferably the throttle valve, which influences the ratio of the fuel-air mixture which is fed to the motor of the vehicle. An adjustment unit adjusts the actuator upon every movement reversal by a definite given amount in the new movement direction.
