To provide a steering assistance device for a vehicle, by which both controllability of steering assistance control and steering feeling of a driver can be achieved.SOLUTION: When a target steering torque calculation unit 32b is in an active state, a DSS_ECU 11 switches an assist steering torque calculation unit 31a from an active state to a non-active state through an assist steering torque output control unit 33 to limit output of assist steering torque. Meanwhile, in a case where a condition in which a steering is held with a handle 4 by a driver is detected even when the target steering torque calculation unit 32b is in an active state, the ECU switches the assist steering torque calculation unit 31a from a non-active state to an active state through the assist steering torque output control unit 33.SELECTED DRAWING: Figure 2

    【課題】操舵支援制御の制御性と運転者の操舵フィーリングとを両立することができる車両の操舵支援装置を提供する。【解決手段】DSS_ECU11は、目標操舵トルク算出部32bがアクティブ状態であるとき、アシスト操舵トルク出力制御部33により、アシスト操舵トルク算出部31aをアクティブ状態から非アクティブ状態へと切り替えてアシスト操舵トルクの出力を制限する一方、目標操舵トルク算出部32bがアクティブ状態であっても、運転者がハンドル4を保舵した状態が検出されている場合には、アシスト操舵トルク出力制御部33により、アシスト操舵トルク算出部31aを非アクティブ状態からアクティブ状態へと切り替える。【選択図】図2
