An induction motor control apparatus controls an induction motor connected to drive wheels by setting a motor torque command value on the basis of vehicle information. The induction motor control apparatus 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 a rotor magnetic flux on the basis of the first excitation current command value. The induction motor control apparatus calculates a first torque command value on the basis of an estimated value of the rotor magnetic flux and the first torque current command value. Further the induction motor control apparatus calculates a second torque command value by applying filter processing to the first torque command value, a natural vibration frequency component of a drive shaft torque transmission system in a vehicle being removed in the filter processing. Then the induction motor control apparatus controls drive of the induction motor on the basis of the first excitation current command value and the second torque current command value.
