A method and a system in a vehicle to control the input torque to a drivetrain member (4) connected to an engine (2) is presented. The method comrises the steps of determining (101, 210) a value of the input torque (Ti) and determining (101, 210) the rotational speed (RPMi) of an input shaft (6) of the drivetrain member (4). A value of a first torque dependent function (Eoi) is calculated (105, 106, 206, 207), based on the rotational speed (RPMi), the value of the input torque (Ti) and a limit value of the input torque (TMax), the value of the input torque (Ti) exceeding the limit value of the input torque (TMax). If the value of the first torque dependent function (Eoi) exceeds a predetermined limit value of the first torque dependent function (EoMax), the input torque is reduced (109, 212).
