Abstract
Apparatus for the automatic engagement and disengagement of the drive components of a motor vehicle, particularly of the drive of at least one additional axle and/or of locks for auxiliary gear and/or differential gear. The apparatus has sensors for sensing the rotary speeds of the wheels and the steering angle of the vehicle and a control unit which activates the drive components individually, simultaneously or in a given sequence as a function of: The travelling speed; the vehicle acceleration; the slip of the wheels; and the movement condition of the vehicle as a function of the steering angle. The apparatus also has an adaptively operating matching electronic system for accounting for the rotary speeds of the wheels and for the steering angle. An advantage of this apparatus is the engaging of required drive components automatically with narrow limit values and tolerances in necessary situations.
