Abstract

A vehicle with all-wheel drive is described, in which not only are the wheels of one axle connected to the drive shaft but the drive shafts are also connected to the engine by way of a differential gear. An electronic differential lock is described in which pressure is adjusted on the individual wheel brakes according to the occurrence of wheel slip.
