Title:
VIBRATION-INHIBITION CONTROL APPARATUS FOR ELECTRICALLY DRIVEN VEHICLE, AND VIBRATION-INHIBITION CONTROL METHOD FOR ELECTRICALLY DRIVEN VEHICLE
Document Type and Number:
WIPO Patent Application WO/2012/011521
Kind Code:
A1
Abstract:
Provided is an electrically driven vehicle, wherein unexpected vibration or shock is inhibited during interruption of torque transmission. An electric vehicle having an electric motor (1) as the motive power source thereof is provided with an F/F calculation unit (91), an F/B calculation unit (92), an adder (97), model evaluation units (93, 95), and target torque value switching units (94, 96). The F/F calculation unit (91) calculates a first target torque value (Tm*1) by F/F calculation. The F/B calculation unit (92) calculates a second target torque value (Tm*2) by F/B calculation using a model (Gp (s)). The adder (97) adds the first target torque value (Tm*1) and the second target torque value (Tm*2), to obtain a motor-torque command value (Tm). The model evaluation units (93, 95) evaluate whether an interruption in the transmission of torque to driving shafts (4) exists. The target torque value switching units (94, 96) stop the F/F calculation and the F/B calculation, while torque transmission is evaluated as being interrupted.
