Abstract
The method for control of an automated starting element such as a starting clutch or starting brake according to the thermal load of the starting clutch, which method regulates the control parameters according to a determined driving state, a tractional resistance and/or an actual clutch temperature, has one control module () which, below a critical control parameter limit starting from which an increased thermal load or an increased wear appears, reduced the friction work of the starting element. The reduction takes place by a reduction of the slipping time by regulating the slip in the starting element and/or by influencing at least one of the parameters (μ, proportional/integral or differential parts, M_Control, p_Gradient or n_Nominal), the number of steps simultaneously used for reducing the friction work increasing with the temperature of the clutch.
