CONTROL SYSTEM OF VIBRATION SUPPRESSION FOR ELECTRIC DRIVE VEHICLE AND METHOD OF VIBRATION SUPPRESSION FOR IT

摘要

FIELD: motor vehicle industry.;SUBSTANCE: electric vehicle having an electric motor (1) as its power source comprises a module (91) of F/F-calculation or operation, a module (92) of F/B-calculation or operation, an adder (97), modules (93, 95) of the model definition and modules (94, 96) of switching the values of the target torque. The module (91) of F/F-calculating calculates the value (Tm*1) of the first target torque by F/F-operation. The module (92) F/B-calculating calculates the value (Tm*2) of the second target torque by F/B-operation using the model (GP(s)). The adder (97) adds the value (Tm*1) of the first target torque and the value (Tm*2) of the second target torque to obtain a value (Tm) of the torque command of the motor. The modules (93, 95) of the model definition evaluate whether the interruption in the transmission of torque to the drive shafts (4) occurs or not. The modules (94, 96) of switching the values of the target torque stop F/F- and F/B-operations, when the interruption of transmission of the torque is confirmed.;EFFECT: suppression or damping of unexpected vibrations or impact shocks during the interruption in the transmission of torque.;10 cl, 9 dwg
