Abstract

The method involves first disengaging the clutch with the vehicle brake operated and a gear selected, determining the engine torque of the drive engine with the clutch disengaged in idle, engaging the clutch until the touching point originating from the previous adaptation cycle or starting value and determining the engine torque, then defining the touching point based on the determined engine torque and idling torque difference. Independent claims are also included for the following: (a) an arrangement for implementing the inventive method (b) and an arrangement for monitoring a position change of a brushless electrical motor.
