Abstract (en)

[origin: EP0027865A1] 1. Apparatus for regulating the travel speed of a motor vehicle having a multi-cylinder internal combustion engine, with an electrical controller (5) whose desired value input (4) is fed with the output signal of a first electrical position pickup (1) coupled with an accelerator pedal (2) and whose actual value input (6) is fed with the output signal of a second electrical position pickup (7) which is connected with a regulating element of an electrical regulating unit (8) which is operatively connected with an element (throttle valve 9) influencing the fuel-air mixture, characterised in that for putting at least one of the cylinders of the internal combustion engine out of operation there are provided switchoff elements controllable electrically in dependence on at least one operating parameter and means (10 to 15) producing electrical control signals for the switchoff elements, the output signal of the first position pickup (1) being fed into said means, and that means (23 to 30) controlled in dependence on the control signals for controlling the switchoff elements are arranged in the line (3) between the output of the first position pickup (1) and the desired value input (4) of the controller (5), for producing a throttle valve jump.
