The procedure makes it possible to estimate the torque (C FC ) transmitted by a friction clutch coupled to the shaft of a motor vehicle engine and controlled by means of an actuator, the procedure comprising the operations of:
- measuring or otherwise determining the angular speed (É E, meas ) of the engine shaft and the torque (C E ) developed by this shaft;
- calculating the difference or error between the measured value (É E, meas ) of the engine shaft's angular speed and an estimated value (É E ) of the said angular speed; and, using an electronic controller (3), determining an estimated value (C FC ) of the torque transmitted by the clutch, corresponding to the calculated value of the said difference or error in the engine shaft angular speed; the estimated value (C FC ) of the torque transmitted by the clutch being used, along with the value measured or otherwise determined (C E ) of the torque developed by the engine shaft, to obtain the said estimated value of the angular speed of the engine shaft (É E ) on the basis of a predetermined mathematical model.
