Abstract
A method is described for adjusting a setpoint operating state of a hybrid drive in a motor vehicle, the hybrid drive including an internal combustion engine and at least two electric motors as the drive motors, and the output shafts of the drive motor being capable of being operatively connected to a drive train of the vehicle, a setpoint operating point of the hybrid drive being adjusted as a function of an instantaneous power demand (output torque) on the hybrid drive and an instantaneous electrical power demand of an electrical system of the vehicle, by determining the speeds and the torques of the drive motors. At least one of the electric motors () is controlled by voltage regulation and the other electric motor(s) () is/are controlled by speed regulation.
