To suppress vibration of a steering wheel due to variation in steering torque when the steering wheel is held while improving responsiveness of steering when the steering wheel is operated.SOLUTION: An ECU (4) includes: a torque current control unit (7) for setting a first current command value to be supplied to a motor (2) in accordance with a value of steering torque; a differential control unit (8) for calculating a torque differential value that is a differential value of the steering torque and setting a second current command value in accordance with the torque differential value and a revolution speed of the motor (2); and a command value calculation unit (10) for calculating a motor current command value to be supplied to the motor (2).SELECTED DRAWING: Figure 1

    【課題】ステアリングホイールの操舵時において操舵の応答性を向上させつつ、ステアリングホイールの保舵時において操舵トルクの変動に起因するステアリングホイールの振動を抑制する。【解決手段】ECU(4)は、操舵トルクの値に応じて、モータ(2)に供給すべき第1電流指令値を設定するトルク電流制御部(7)と、操舵トルクの微分値であるトルク微分値を算出し、トルク微分値及びモータ(2)の回転速度に応じて、第2電流指令値を設定する微分制御部(8)と、モータ(2)に供給すべきモータ電流指令値を算出する指令値算出部(10)と、を備える。【選択図】図1
