发明名称 Method and device for controlling the clutch of a vehicle
摘要 The control method comprises the stages of: generating a reference torque signal (CRIF), the instantaneous value of which indicates the desired value of the torque transmitted through the clutch (5); generating a reaction signal (X) correlated to the position of an actuating member (4) of the clutch (5), the position of the actuating member (4) being comprised between a first end-of-travel position in which the clutch (5) is completely open and a second end-of-travel position in which the clutch (5) is completely closed; generating an estimated torque signal (CST), the instantaneous value of which indicates the estimated value of the torque transmitted through the clutch (5), on the basis of the reaction signal (X) and a transmissibility function (F(X)) of the clutch (5); and generating a control signal (CM) for adjusting the position of the clutch (5) as a function of the reference torque signal (CRIF) and the estimated torque signal (CST). The method comprises, moreover, the stage of updating the transmissibility function (F(X)) of the clutch (5) during operation of the clutch (for example at acceleration of the vehicle) so as to adapt it to the variations, over time, in the mechanical characteristics of the clutch (5) itself. <IMAGE>
