Summary:To provide a steering control device that is able to achieve stable execution of drive assistance control.SOLUTION: In a case where a flag F is input and the absolute value of a detection torque Th is smaller than a threshold, an assist control unit 71 calculates an amount Tas* of assist control, which has an opposite sign of the detection torque Th, in order to offset the detection torque Th. Then, using an amount Ta* of assist control, calculated by the assist control unit 71, and an ADAS command value Tad*, input to a steering control device 50 from an ADAS control device 100, an adder 75 calculates a final command value T*.SELECTED DRAWING: Figure 2 【課題】運転支援制御の安定した実行を実現できる操舵制御装置を提供する。【解決手段】アシスト制御部７１は、フラグＦが入力され、かつ検出トルクＴｈの絶対値が閾値未満である場合、検出トルクＴｈを相殺するべく検出トルクＴｈと逆符号のアシスト制御量Ｔａｓ＊を演算する。そして、加算器７５は、アシスト制御部７１により演算されたアシスト制御量Ｔａ＊及びＡＤＡＳ制御装置１００から操舵制御装置５０に入力されたＡＤＡＳ指令値Ｔａｄ＊を用いて、最終指令値Ｔ＊を演算する。【選択図】図２
