Method of operating a combustion engine

The invention relates to a method of operating a combustion engine (10), wherein a clutch torque (M_cl) of said combustion engine (10) is determined, characterized in that a value (M_É_k) of said clutch torque (M_cl) for a specific, particularly k-th, operating cycle of said combustion engine (10) is determined depending on a value (M_É_k-1) of said clutch torque (M_cl) for a preceding, particularly (k-1)-th, k=1, 2, 3, .., operating cycle of said combustion engine (10), and on a delta torque value (”M) characterizing a change of said clutch torque (M_cl) between said preceding operating cycle and said specific operating cycle.
