ABSTRACT:
A speed control apparatus is proposed for motor vehicles driven by internal combustion engines and having a hydraulic connecting line between a first hydraulic adjusting cylinder, which is actuatable by the gas pedal, and a second hydraulic adjusting cylinder, which is connected with the throttle valve, the regulating rod of an injection pump in the case of Diesel engines, and the like for adjusting the operating status of the engine. A multiple-position valve is furthermore disposed in the hydraulic connecting line, this valve receiving control commands from an electronic control circuit. The electronic control circuit compares its input signals, provided by transducers, from the first and second hydraulic adjusting cylinders and reacts further such as to provide a supervisory intervention in further regulating control subsystems for the purpose of engine regulation.
