Abstract
A method and device for dynamic torque coordination of power units of a hybrid drive of a vehicle, in particular a motor vehicle. The method has a plurality of successive coordination stages, each coordination stage being assigned an operating range for at least one of the power units, and each coordination stage making at least one demand on a first power unit and/or a second power unit as a function of an overall setpoint torque requested from the hybrid drive, a subsequent coordination state having an enlarged operating range compared to a preceding coordination stage, and the subsequent coordination stage is used if the demand was unable to be satisfied within the operating range of the assigned coordination stage.
