Abstract

In a method for determining the torque of an internal combustion engine of a motor-vehicle hybrid drive device which further includes a secondary electric motor coupled to the internal combustion engine, the torque of the internal combustion engine is determined at at least one operating point by comparison to the known torque of the secondary motor.
