This induction motor control device, which sets a motor torque command value on the basis of vehicle information and controls an induction motor connected to the drive wheels, calculates a first torque current command value and a first excitation current command value on the basis of the motor torque command value and estimates the rotor flux on the basis of the first excitation current command value. This device further calculates a first torque command value on the basis of the estimated rotor flux value and the first torque current command value, and calculates a second torque command value by performing filter processing on the first torque command value to remove the natural resonance frequency component of the drive shaft torque transmission system of the vehicle. This device then calculates a second torque current command value on the basis of the second torque command value and the estimated rotor flux value, and controls the driving of the motor on the basis of the first excitation current command value and the second torque current command value.
