Abstract
The invention relates to a method for controlling a coupling device between an input shaft driven by a motor and an output shaft that can transmit a maximum torque according to the position of an actuator of the coupling devicecomplying with a law of behavior of the coupling means according to which: a set value (Cemb,cons) of maximum torque to be transmitted is defined; the actual position (Xemb,mes) of the actuator of the coupling device is measured; a set value (Xemb,cons) is determined for actuating the coupling device and is sent to the actuator of the coupling device, while using a law of behavior of the coupling means obtained by interpolation between a first law of reference of behavior of the coupling means and at least one second law of reference of behavior of the coupling means, and; an auto-adaptation of the law of behavior of the coupling means is carried out for taking into consideration its evolution resulting from the use. The method can be used for controlling the clutch of a drive train of a motor vehicle.
