    摘要: A method for controlling a motor vehicle drive, in particular a hybrid drive, is provided, the motor vehicle drive having at least two individual motors. In a first method step, at least one total setpoint torque is calculated. In a second step, the at least one total setpoint torque is split into at least two individual setpoint torques of the at least two individual motors. Subsequently, in a first individual torque comparison step, the sum of the at least two individual setpoint torques is compared with the total setpoint torque. In the event of a difference by more than a predefined tolerance value, a limitation step is initiated. In this limitation step, the at least two individual setpoint torques are each multiplied by a limiting factor to generate at least two limited individual setpoint torques.

    摘要: A method is provided for regulating the rotational speed in a hybrid drive of a vehicle having a first drive source, in particular an internal combustion engine, and a second drive source, in particular an electric motor. A rotational speed variable which is a function of a rotational speed of the first drive source and of a rotational speed of the second drive source is determined. The rotational speed of the first drive source or of the second drive source is regulated based on the rotational speed variable for oscillation reduction.The rotational speed variable used is preferably a mean value of the two rotational speeds. The two rotational speeds may be weighted on the basis of inertia in order to form the mean value as well.

    摘要: A method and a device for operating a drive unit which enable better torque coordination for a speed controller. A load-reversal damping component is provided, which filters a first setpoint value for an output variable of the drive unit to damp a load reversal. A speed controller is provided, which specifies a second setpoint value for the output variable of the drive unit in order to adjust an actual value for an engine speed of the drive unit to a setpoint value for the engine speed. A first component of the second setpoint value for the output variable specified by the speed controller is taken into account in the formation of the first setpoint value. A remaining second component of the second setpoint value for the output variable specified by the speed controller, together with the filtered first setpoint value, is taken into account only when forming a resulting third setpoint value for the output variable, the first component of the second setpoint value for the output variable specified by the speed controller being formed as a function of at least one characteristic of the load-reversal damping component, in such a way that it is not or only negligibly affected by the filtering.
