Abstract
For improving the load-change behavior of a four-wheel drive motor vehicle when driving through curves, the vehicle is provided with a longitudinal clutch continuously controllable and with a lockable differential continuously controllable in its locking action. The activation of the longitudinal clutch takes place in the first instance in dependence on velocity whereas the activation of the lockable differential is undertaken in the first instance in two stages dependent on power output whereby a velocity-dependent characteristic can additionally be super-imposed on this power output dependent control.
