DRIVE SYSTEM, IN PARTICULAR A DRIVE SYSTEM FOR A MOTOR VEHICLE, AND METHOD OF OPERATING THE SYSTEM

摘要

The invention concerns a drive system, in particular a drive system for a motor vehicle, with a drive unit, in particular an internal-combustion engine, and at least one electrical machine (4) which acts, in order to actively reduce rotational non-uniformity, on the drive unit, and in particular on the drive shaft (10) or a shaft which is coupled, or can be coupled, to the drive shaft. At least one drive-system sensor (16, 32) and/or at least one control parameter derived from the sensor information is used to control both the drive unit and the electrical machine (4), and/or a control device (31 or 33), respectively responsible for control of the electrical machine (4) or the drive unit, also partly or wholly controls the drive unit or the electrical machine (4). The invention also concerns a method of operating a drive system of this kind.
