VIBRATION-INHIBITION CONTROL APPARATUS FOR ELECTRICALLY DRIVEN VEHICLE, AND VIBRATION-INHIBITION CONTROL METHOD FOR ELECTRICALLY DRIVEN VEHICLE

摘要

Provided is an electrically driven vehicle, wherein unexpected vibration or shock is prevented during interruption of torque transmission. An electric vehicle having an electric motor (1) as the power source thereof is provided with an F/F calculation or operation unit (91), an F/B calculation or operation unit (92), an adder (97), model determination 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 operation. The F/B calculation unit (92) calculates a second target torque value (Tm*2) by F/B operation 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 determination units (93, 95) evaluate whether or not an interruption in the torque transmission to drive shafts (4) occurs. The target torque value switching units (94, 96) stop the F/F and F/B operations while torque transmission interruption is confirmed.
