Automated Manual Transmission (AMT) systems are generally constituted by a dry or wet clutch assembly and a multi-speed gearbox, both equipped with electro-mechanical or electro-hydraulic actuators, which are driven by a control unit, the transmission control unit (TCU). In this transmission type the quality of the vehicle propulsion as perceived by the driver is largely dependent on the quality of the control strategies. This paper aims at providing to control engineers a reliable mathematical model of the frictional torque characteristic of 'actively closed' dry clutch along with the influence of the temperature on the characteristic.

Abstract
Automated Manual Transmission (AMT) systems are generally constituted by a dry or wet clutch assembly and a multi-speed gearbox, both equipped with electro-mechanical or electro-hydraulic actuators, which are driven by a control unit, the transmission control unit (TCU). In this transmission type the quality of the vehicle propulsion as perceived by the driver is largely dependent on the quality of the control strategies. This paper aims at providing to control engineers a reliable mathematical model of the frictional torque characteristic of 'actively closed' dry clutch along with the influence of the temperature on the characteristic.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
