Abstract
Official abstract text for this publication.
A method for changing a drive unit's mechanical coupling to a motor vehicle power train, which has at least two drive units, in which at least one first drive unit of the two drive units is coupled via various mechanical couplings, including mechanical transmission ratios, during the travel of the motor vehicle, a power or torque influence of the two drive units occurring if there is a change of the mechanical coupling. To ensure a change of the mechanical coupling without the vehicle occupants perceiving it, the change of the mechanical coupling of the first drive unit of the two drive units occurs in at least two operating modes, a first operating mode causing a slower operating point change with respect to time of the two drive units, while a more rapid operating point change as to time of the two drive units is provided in a second operating mode.
First claim
Opening claim text (preview).
What is claimed is: 1. A transmission control unit, which activates a transmission including at least one clutch for shifting a mechanical coupling of a first drive unit, comprising: an arrangement configured to output a request signal for setting a first or a second operating mode, or to change between the first and second operating modes, wherein the first operating mode causes a slower torque operating point change with respect to time of a torque produced by the first drive un…
