Abstract
A reversing method for reversing a travel direction of a working machine with a power-split transmission in which control signals are emitted by a control unit such that a reversing clutch, for the current travel direction, is disengaged and a reversing clutch for the new travel direction is engaged. The reversing clutches are controlled by control variables. If there is a difference between a reference control magnitude and a target control variable, the control variable is adapted. An adapted control signal is emitted, with which the reversing clutches are actuated, and for determining the target control variables for the disengaging and engaging of the reversing clutches, in addition to a translational factor and a rotational factor a load-dependent factor is determined and processed.
