Method and device for changing the mechanical coupling of a drive unit to a drive train of a motor vehicle whose drive train is equipped with at least two drive units

摘要

The invention relates to a method for changing the mechanical coupling of a drive unit to a drive train of a motor vehicle, the drive train of which is equipped with at least two drive units, in which at least a first (2) of the two drive units (2, 3) during the journey of the motor vehicle over different mechanical couplings, in particular mechanical transmissions (iEIM), is coupled, with a change in the mechanical coupling a power or torque influence of the two drive units (2, 3) takes place. In order to ensure a change in the mechanical coupling without the vehicle occupants noticing it, the mechanical coupling of the first (2) of the two drive units (2, 3) is changed in at least two operating modes, with a first operating mode changing the operating point of the two slowly over time Drive units (2, 3) causes, while in a second operating mode a faster change in the operating point of the two drive units (2, 3) is made possible.
