To reduce force necessary for steering while maintaining straightforward stability of a vehicle.SOLUTION: A steering assist apparatus for use in assisting the steering of a vehicle having a king-pin offset includes: a detection part for detecting a steering angle of a steering wheel; and an assist part for changing travel torque on the basis of assist torque being a value that increases with the steering angle in the case of the steering angle being equal to or higher than a threshold and, and a value equal to or less than a minimum value in the case of the steering angle being equal to or more than the threshold in the case of the steering angle being less than the threshold. Further, while the steering angle is increasing, the assist part increases travel torque of a first motor for use in driving a steering wheel of the vehicle on the internal side of turning by an amount equivalent to the assist torque, and increases travel torque of a second motor for use in driving the steering wheel of the vehicle on the outer side of turning by the amount equivalent to the assist torque.SELECTED DRAWING: Figure 2

    【課題】車両の直進安定性を維持しつつ、操舵に必要な力を小さくする。【解決手段】操舵アシスト装置は、キングピンオフセットを有する車両の操舵をアシストする操舵アシスト装置であって、ステアリングホイールの舵角を検出する検出部と、前記舵角が閾値以上である場合には前記舵角が大きいほど大きく、前記舵角が閾値未満の場合には、前記舵角が閾値以上である場合の最小値以下の値であるアシストトルクに基づいて、走行トルクを変化させるアシスト部と、を備え、前記アシスト部は、前記舵角が増加している間、前記車両の旋回内側の操舵輪を駆動する第1のモータの走行トルクを、前記アシストトルク分減少させ、前記車両の旋回外側の操舵輪を駆動する第2のモータの走行トルクを、前記アシストトルク分増加させる。【選択図】図2
