Abstract: A device for regulating the traveling speed of a motor vehicle, comprising an electric regulator acted upon by a speed-responsive signal, which regulator compares the prevailing travel-speed with a prespecified desired traveling speed and, in the case of a deviation of the actual traveling speed from the prespecified one, emits a signal proportional to the deviation variable. The device comprises a pneumatic adjusting drive, preferably the accelerator, which acts upon an element affecting the ratio between fuel and air in the fuel-air mixture fed to the motor vehicle engine. The adjusting drive is in turn acted upon by a vacuum or excess pressure or normal pressure by way of a control stage which is responsive to a signal emitted by the regulator.
