Patent ID: 7949453

Claim:
A method for the control of a clutch arrangement which serves, in a powertrain of a motor vehicle, for the transmission of a torque from an input element to an output element, comprising: activating the clutch arrangement; calculating an estimated torque value (M_est) in repeating calculation cycles including: calculating a torque build-up value (ΔM_up) in dependence on at least one speed difference value (Δn) that corresponds to a speed difference between the input element and the output element; calculating a torque reduction value (ΔM_down) in dependence on at least the last calculated estimated torque value (M_est); recalculating the estimated torque value (M_est) on the basis of the last calculated estimated torque value by up integration of the calculated torque build-up value and down integration of the calculated torque reduction value; and comparing the recalculated estimated torque value (M_est) with a torque threshold value (Thresh_M); and deactivating the clutch arrangement when the recalculated estimated torque value is below the torque threshold value.
