Abstract
A process that estimates the torque transmitted by a friction clutch coupled to the shaft of a motor vehicle engine. The process includes determining the angular speed of the engine shaft and the torque developed by this shaft; calculating the difference between the measured value of the engine shaft's angular speed and an estimated value of the angular speed; and determining an estimated value of the torque transmitted by the clutch, corresponding to the calculated value of the difference or error in the engine shaft angular speed. The estimated value of the torque is used, along with the value measured or otherwise determined of the torque developed by the engine shaft, to obtain the estimated value of the angular speed of the engine shaft on the basis of a predetermined mathematical model.
