A method for determining operating conditions of a working machine () having a vehicle drive-train () while the working machine () is operating. The operating conditions are determined by a classifier generated by a machine learning process. By way of the classifier, the values of at least one operating variable of the vehicle drive-train (), determined while the working machine () is operating, can be assigned to respective predefined categories which, in each case, represent at least one operating condition of the working machine.

Method for determining operating conditions of a working machine comprising a vehicle drive train while operating the working machine

A power-split transmission which is designed to be operated with either first or second deceleration logics. The second deceleration logic has a higher deceleration dynamic than the first deceleration logic, and is designed to disengage an engaged range clutch immediately so as to reduce the transmission ratio by way of a hydrostatic unit with a maximum dynamic. A method of operating the transmission includes: monitoring various vehicle parameters while the vehicle is operated with the first deceleration logic; detecting that at least one set limit value has been exceeded while the vehicle operated with the first deceleration logic; activating the second deceleration logic, to immediately disengage an engaged range clutch; reducing a transmission ratio to a maximum using the hydrostatic unit, the hydrostatic unit being displaced with a maximum dynamic; and engaging the range clutch and activating the first deceleration logic.
