Abstract

A vehicle control device for decelerating by the regenerative braking of a motor connected to a drive shaft of a drive wheel calculates a torque command value for suppressing a vibration component of the drive shaft by feeding back a torsional angular velocity of the drive shaft to a desired torque that determines the power of the motor and controls the operation of the motor on the basis of the torque command value. The control device estimates a dead zone section, in which the torque of the motor in the vehicle is not transmitted to the drive shaft, on the basis of the desired torque and limits the torque command value in the case where the vehicle is in the dead zone section.
