Abstract
A drive system for an axle of a motor vehicle can be controlled. The drive system can have at least one drive unit driving a drive shaft, a first output shaft, and a second output shaft, as well as first and second clutches connecting the drive shaft to the first and second output shafts, respectively. A control unit of the drive system controls the clutches to operate at least at certain operating points with a micro-slip control in which a speed differential between the drive shaft and the output shaft of >0 revolutions per minute (RPM) and <50 RPM is set for the respective clutch. A travel state of the motor vehicle can be detected, including detecting: traveling straight ahead and cornering in the pull mode, and a control strategy can be selected and applied for each clutch, wherein the control strategy is different for different travel states.
