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

摘要

The invention observer of such, in particular influenza Burger observer type on torque control module of the frictional engagement means for jonjo between the input shaft gear box associated with the drive shaft belonging to a motor vehicle drive train including the 50 and observer an estimate (X *) of the state variables representing the complete current dynamic state of the dynamic mathematical model 52 implementation, the transmission chain 13 for simulating the dynamic performance of the unit transmission chain (13) of the vehicle according to the measured state variables (Y), measured command variable (U) and the evolution matrix (a) and the correction matrix (L) is calculated on the basis of the estimate (X *) of the state variable to the preceding.
