Automated Manual Transmissions (AMTs) represent an affordable and robust driveline solution but the quality of the vehicle propulsion perceived by the driveris largely dependent on the quality of the control strategies. This paper aims at investigating the engagement performance of actuated dry clutch in AMTs by taking into account a more detailed frictional characteristic identified through specific tribological test patterns. The outcome of this analysis provides information for designers of automated clutches to overcome poor engagement performances due to defective prediction of operating condition variables as contact pressure, sliding speed and temperature influence on the frictional behaviour of facing materials.

Abstract
Automated Manual Transmissions (AMTs) represent an affordable and robust driveline solution but the quality of the vehicle propulsion perceived by the driveris largely dependent on the quality of the control strategies. This paper aims at investigating the engagement performance of actuated dry clutch in AMTs by taking into account a more detailed frictional characteristic identified through specific tribological test patterns. The outcome of this analysis provides information for designers of automated clutches to overcome poor engagement performances due to defective prediction of operating condition variables as contact pressure, sliding speed and temperature influence on the frictional behaviour of facing materials.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
