ABSTRACT:
A method for determining a transmittable torque of a clutch of an automatic transmission of a motor vehicle, in particular an automated shift transmission, uses the clutch for transmitting torque from an engine shaft to a transmission input shaft and uses a synchronizing device for selectively engaging and disengaging a gear stage in the automatic transmission. The gear stage is pre-synchronized with the synchronizing device by applying a given synchronizing force to the synchronizing device but without engaging the gear stage. Speeds of the engine shaft and of the transmission input shaft are measured. The torque transmitted by the clutch is determined by comparing the speeds of the engine shaft and of the transmission input shaft while taking into account a current synchronizing force.
