ABSTRACT:
An automatic activation apparatus for a differential pawl which is independent of intervention by an operator of a vehicle, the invention controls the energy supply to the actuator by means of a control logic with two signal inputs. The control logic is fed a wheel slip signal directly at one signal input, and via a break-delay timing element at its other signal input. The control logic is thereby designed so that, by the excitation of both signal inputs, it switches into a standby position and then into its active position only upon the excitation of its signal input connected with the timing element.
