Patent ID: 8167065

Claim:
A method for dynamic torque coordination of power units of a hybrid drive of a motor vehicle, comprising: assigning each of a plurality of successive coordination stages an operating range for at least one of the power units; making, by each coordination stage, at least one demand on at least one of a first power unit and a second power unit, as a function of an overall setpoint torque demanded from the hybrid drive; and using a subsequent coordination stage if the demand was unable to be satisfied within the operating range of the assigned coordination stage, the subsequent coordination stage having an enlarged operating range as compared to a preceding coordination range; wherein, if a demand on a power unit is unable to be satisfied within the operating range of the coordination stage, the demand is forwarded, in full or in part, to another power unit, and wherein one of the power units is an electric machine, and wherein the electric machine is operated in at least one of the coordination stages at an electric machine setpoint torque having one of a restricted torque or a restricted torque gradient.
