Abstract:
1. A method for operating a hybrid drive system, which has a first drive unit, which is an internal combustion engine, and a second drive unit, which is an electric motor, the method comprising: activating the first drive unit and the second drive unit so that the first drive unit and the second drive unit each provide an output variable for providing a total output variable; limiting the output variable provided by the first drive unit to a preset limiting value which is less than a maximum output variable provided by the first drive unit; and canceling the limiting of the output variable provided by the first drive unit when the output variable provided by the second drive unit corresponds to a maximum output variable provided by the second drive unit and a kickdown is detected in which an accelerator pedal of a vehicle equipped with the drive system is fully deflected at least at a predetermined rate of change.
