Abstract
A method is for controlling the torque of a hybrid drive unit, which includes a combustion engine and at least one electric machine capable of being operated alternatively as a motor or as a generator. The electric machine, when operated as a motor, is powered by an energy storage device and supplies a positive electric motor torque which together with a combustion engine torque of the combustion engine produces a total drive torque of the hybrid drive unit. A hybrid drive unit includes a respective torque control. In the event that a desired torque is greater than a consumption-optimized combustion engine maximum torque, the electric machine is operated as a motor having an electric motor torque. An electric motor maximum torque is specified as a function of at least one state parameter of the energy storage device.
