Abstract

For improving the load-change behavior of a motor vehicle when driving through a curve, the motor vehicle is provided with a lockable differential continuously activatable in its locking action. The activation of the locking differential takes place in the first instance in two steps dependent on power output, whereby a velocity-dependent characteristic may be superimposed additionally on this power output-dependent control.
