Title:
Method for operating a drive train
Abstract:
A method of operating a drive-train comprising an auxiliary output on the engine side that can be coupled to the combustion engine via a continuously variable transmission and a generator such that when the engine is running, the generator can be driven at a constant rotational speed regardless of the speed of the engine, such that a condition parameter of the auxiliary output is regulated between a pair of limit values. The condition parameter is regulated as a function of its current actual value, the limit values of the condition parameter and also as a function of a current and/or anticipated driving situation such that parameters are determined, in the regulator, for the energy input into the auxiliary output as a function of these input data, and hence for a corresponding energy uptake from the engine.
