Abstract
In a method for operating a drive unit comprised of an internal combustion engine and a hydraulic aggregate group, the amount of fuel supplied to the engine is limited by a proportionally acting RPM regulator. When the engine is overloaded the power absorption of the hydraulic aggregate group is reduced by an electronic maximum load regulator and under no-load operation the engine is shifted from an automatic idling circuit to the idling speed after a specified time and the power absorption of the aggregate group is reduced to a minimum. For partial-load operation, the power absorption of the aggregate group can be limited selectably to a power below the maximum power put out by the engine. In order to render such a process more economical, the engine is operated in the range of the idling control characteristic during partial-load operation. The output power of the hydraulic aggregate group and the output power of the engine is thus reduced, by which the hydraulic aggregate group can continue to operate with an approximately constant speed in spite of the reduced power.
