A method for driving a hybrid vehicle during a load reversal includes: the application of a first torque on a first hybrid vehicle axle during an acceleration reversal; and the application of a second torque on a second hybrid vehicle axle during the acceleration reversal, a direction of action of the second torque being opposite to a direction of action of the first torque.

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.

A method is described for starting an internal combustion engine having an E-machine coupled to it in a motor vehicle, after the input of a certain torque command at a drive control of the internal combustion engine, the internal combustion engine being accelerated for the start by the E-machine, and the internal combustion engine being set by the drive control, via actuators, to specified characteristics values for the start. To reduce exhaust gas emissions at the start of the internal combustion engine, the internal combustion engine is accelerated by the E-machine, without the injection of fuel, until the engine torque that is able to be implemented by the internal combustion engine, essentially corresponds to the torque command, and the injection of fuel into the internal combustion engine is only then released.
