Patent ID: 7593799

Claim:
A torque transmission device in a motor vehicle for the variable transmission of a torque from a first shaft, assigned to a first wheel pair, to a second shaft, assigned to a second wheel pair, the device comprising: a clutch unit for variable torque-transmitting coupling of the first and second shafts, said clutch unit having at least one first clutch element connected in rotation-transmitting manner to the first shaft and at least one second clutch element connected in a rotation-transmitting manner to the second shaft, said first and second clutch elements being disposed to be, or to be placed, into torque-transmitting interaction with one another; controllable actuating means for setting an intensity of the interaction between said first and second clutch elements by adjusting at least one of a relative position and a mechanical pressing force of said clutch elements; a control device for actuating said actuating means, said control device including a data processing unit configured to: calculate a first control signal based on a plurality of input signals and in accordance with predefined rules; superimpose a second control signal on the first control signal, the second control signal being a measure of a difference between a rotational speed of the first shaft and a rotational speed of the second shaft, wherein a change in the second control signal due to a change in the difference brought about by a given driving situation temporally precedes a change in the first control signal caused by the given driving situation; and output an output signal with the first control signal and the second control signal superposed thereon for actuating said actuating means.
