Procedure to improve the accuracy of a key point measurement of an automated coupling in a vehicle with an internal combustion engine

摘要

The invention relates to a method for improving the precision when ascertaining the touch point of an automatic clutch in a motor vehicle with an internal combustion engine, wherein the clutch characteristic curve is adapted using the touch point. In order to improve the torque precision, the touch point is ascertained on the basis of the torque of the clutch (4), which is ascertained depending on the drag torque of the coasting internal combustion engine (2).
