Abstract
The invention concerns a drive control for motor and utility vehicles. The speeds of the wheels and the steering angle are measured by means of sensors. Driving axle slip is determined by comparing the average peripheral wheel speeds of the driven and non driven axles and by taking into account the steering geometry. Driving force and finally chassis efficiency are determined by the slip with the assistance of standard characteristic lines. The efficiencies of all-wheel drive and rear-wheel drive are compared. The drive with the higher degree of efficiency is engaged.
