Claim 10:
11. A control unit for a motor vehicle, the motor vehicle at least having a drive system for at least one axle of the motor vehicle, wherein the drive system has at least one drive unit, a drive shaft driven by the drive unit, a first output shaft and a second output shaft, and a first clutch connecting the drive shaft to the first output shaft and a second clutch connecting the drive shaft to the second output shaft, and furthermore a control unit for controlling the clutches, wherein the control unit comprises a computer including a processor and is configured for operating the drive system, including by:
a) establishing a travelling state of the motor vehicle, wherein at least the following travel states are detected: traveling straight ahead, cornering in a push mode, and cornering in a pull mode; and
b) selecting and applying one of a plurality of control strategies for each clutch, wherein the selected and applied control strategy is different for different travel states, and
wherein the plurality of control strategies include:
a first control strategy for a straight-ahead travel state;
a second control strategy for the cornering in the push mode travel state comprises a micro-slip control for the clutch on the inside of the curve, wherein the clutch on the outside of the curve as a function of the clutch on the inside of the curve is controlled so that a first outside torque transmitted by the clutch on the outside of the curve corresponds to a second inside torque of the clutch on the inside of the curve, said second inside torque having been varied by a factor; and
a third control strategy for the cornering in the pull mode travel state comprises a micro-slip control for the clutch on the outside of the curve, wherein the clutch on the inside of the curve is controlled as a function of the clutch on the outside of the curve such that a first inside torque transmitted by the clutch on the inside of the curve corresponds to a second outside torque of the clutch on the outside of the curve, said second outside torque having been varied by a second factor.
