    摘要: According to the method the crossover phase of the friction clutches is performed by defining a linear torque profile for the first friction clutch having a given initial value and a zero final value, a linear torque profile for the second friction clutch having a zero initial value and a given final value, and a linear torque profile for the engine having a given initial value and a given final value. The final value of the torque profile of the second friction clutch is calculated, the initial value of the engine torque being known, by determining a final value of the longitudinal acceleration of the vehicle equal to a given percentage of the initial value of the longitudinal acceleration of the vehicle. The final value of the engine torque profile is calculated, the final value of the torque profile of the second friction clutch being known, on the basis of the final value determined for the longitudinal acceleration of the vehicle. The initial value of the torque profile of the first friction clutch is chosen so as to be greater than a minimum value calculated by determining the condition of synchronism of the driving shaft and of the first primary shaft.

    摘要: 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.
