Zusammenfassung
(EN)

A method for determining the contact point for a clutch in a vehicle comprising an engine, a clutch, powered wheels and a gearbox. The gearbox has a first gearbox component which is connected to the clutch and disconnectable from the powered wheels. The method steps include estimating (405) a friction torque for the first gearbox component, whereby the torque transmitted by the clutch is a function of estimated friction torque, closing (407) the clutch, whereby a representation of a torque transmitted by the clutch is determined for a plurality of positions for the clutch, determining (409) the contact point by means of the determined representation of torque transmitted, and the further step (402), before the closure of the clutch, of accelerating the first gearbox component if its rotation speed is below a certain value. Also a system and a vehicle for performing the method are disclosed.
