PROBLEM TO BE SOLVED: To reduce or overcome driver's uncomfortable feeling in steering operation upon steering intervention is executed during automatic steering.SOLUTION: A steering support apparatus 10 in a vehicle 500 comprising a steering operation input apparatus 41 and a stirring transmission apparatus 42 which differentially function at a transmission ratio as a ratio of a stirring transmission angle change level relatively to a stirring operation angle change level, comprises: a stirring transmission apparatus driving part 32 driving the stirring transmission apparatus 42; and a controlling part 100 which determines a stirring transmission angle based on at least either of a traveling mode or traveling road information of the vehicle 500 and executing an automatic steering mode where the stirring transmission apparatus driving part 32 is controlled to achieve the determined stirring transmission angle. When an input change is detected from the steering operation input apparatus 41 during execution of the automatic steering mode, the controlling part 100 changes a transmission ratio to a smaller value than a transmission ratio for the automatic steering mode and gives priority to a manual steering mode where the stirring transmission apparatus 42 acts depending on steering angle input via the steering operation input apparatus 41 rather than the automatic steering mode.SELECTED DRAWING: Figure 2

    【課題】自動操舵中に操舵介入が実行された際における、運転者の操舵操作の違和感を低減または解消する。【解決手段】操舵角の変化量に対する転舵角の変化量の比である伝達比にて差動する操舵入力装置41および転舵装置42を有する車両500における操舵支援装置10は、転舵装置42を駆動する転舵装置駆動部32と、車両500の走行状態または走路情報の少なくともいずれか一方に基づき転舵角を決定し、決定された転舵角を実現するように転舵装置駆動部32を制御する自動操舵モードを実行する制御部100を備える。制御部100は、自動操舵モードの実行中に操舵入力装置41からの入力変動が検出されると、伝達比を自動操舵モード時における伝達比よりも小さい値に変更し、操舵入力装置41を介して入力される操舵角に応じて転舵装置42が作動する手動操舵モードを自動操舵モードに優先させる。【選択図】図2
