Claim One:
1. A procedure for estimating the torque Ĉ 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 of the engine shaft ω E,meas and the torque developed by this shaft C E ; calculating the difference or error between the measured value of the engine shaft's angular speed ω E,meas and an estimated value of the angular speed {circumflex over (ω)} E ; and, using an electronic controller, determining an estimated value of the torque transmitted by the clutch Ĉ FC , corresponding to the calculated value of the difference or error in the engine shaft angular speed; the estimated value of the torque transmitted by the clutch Ĉ FC being used, along with the value measured or otherwise determined of the torque developed by the engine shaft C E , to obtain the estimated value of the angular speed of the engine shaft {circumflex over (ω)} E on the basis of a predetermined mathematical model.
