MODELS FOR PRESSURE CONTROL OF AUTOMATED DRY CLUTCHES: TEMPERATURE INFLUENCE ON FRICTIONAL AND ELASTIC BEHAVIOUR

Automated Manual Transmissions (AMTs) 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 investigating the influence of the temperature on the engagement performance of an actively closed dry clutch.
