PROBLEM TO BE SOLVED: To control "torsional vibration" between a motor and wheels.SOLUTION: An ECU 5 includes: a condition determination part 51 which determines whether a motor generator is in a driven state; a first variation detection part 52 which detects the revolutions of the motor generator at each predetermined time to obtain a revolution variation integrated value; a first variation determination part 53 which determines whether revolution variation is occurring in the motor generator according to whether the revolution variation integrated value is equal to or larger than a threshold value; and a torque imparting part 54 which imparts torque in an opposite phase to the revolution variation to the motor generator when the motor generator is determined to be in the driven state by the condition determination part 51 and when the revolution variation is determined to be occurring in the motor generator by the first variation determination part 53. |
