A method for controlling a driving dynamics function of a working machine with at least two vehicle axles. A current actual wheel rotational speed of at least one wheel is detected and sent to a control unit for comparison with an acceptable wheel rotational speed of the same wheel and wheel slip is calculated from that comparison. The control unit emits a control signal to lock at least one differential gear system if the wheel slip has an unacceptable value. For the differential gear system () concerned, an unlocking control signal is periodically emitted and the wheel rotational speeds are compared afresh. A control signal to lock the differential gear system concerned is emitted again if the value of the wheel slip is still unacceptable, and a trajectory is detected with reference to detection elements, along which the value of the wheel slip of the at least one wheel has been unacceptable.

Method for controlling a driving dynamics function of a working machine

A method of starting or holding a mobile vehicle and, in particular, a working machine. The method determines whether the vehicle is rolling backward on an inclined surface and, as a function of that knowledge, the rotational speed of the drive engine is increased, or a downshift by one gear is carried out in the transmission.
