MODULE FOR THE TORQUE CONTROL OF FRICTION COUPLING MEANS OF A MOTOR VEHICLE DRIVE TRAIN COMPRISING A STATE OBSERVER

摘要

The present invention provides a means of frictional engagement between jonjo motor vehicle gearbox input shaft associated with the drive shaft belonging to the drive train relates to a torque control module , in particular comprising the observer 50 of the observer type influenza Berger , observer implements the dynamic mathematical model (52) simulating the dynamic performance of the units of the transmission chain (13) of the vehicle and the transmission chain estimates of the state variables representing the current dynamic state of complete (13) (X *) is the state variable measured (Y), the preceding command in response to the measured variable (U) and the evolution matrix (A) and the correction matrix (L) and calculating on the basis of the estimate (X *) of the state variables . ;
