The present invention relates to a motor vehicle comprising an internal
combustion engine and a first electronic control unit (48) for
controlling the engine depending on the setting of a manual throttle, an
electronic control unit (45) for controlling the transmission, depending
on a set position of a manual gear selector (46). The invention is
characterized in that one of the control units is disposed, with fed-in
parameters and thus at least knowledge of the target speed of the
vehicle, the surrounding topology and the throttle opening position, to
reduce the throttle opening, in those cases where the vehicle, relative
to the target speed, has a speed below target speed and gravity can
subsequently accelerate the vehicle. In a similar manner, the kinetic
energy of the vehicle is used, in those cases where the vehicle has an
above target speed and gravity can subsequently retard the vehicle.
