DRIVING SUPPORT DEVICE

To provide a driving support device capable of eliminating fear of a driver when an own vehicle during an operation of a lane keeping support function comes into the in-parallel travel state with another vehicle.SOLUTION: A target course is set at the center of a lane on which an own vehicle V1 is traveling by an LKA function. Then, steering control is performed so as to allow the vehicle V1 to travel on the target course. When another vehicle V2 is detected and it is determined that the other vehicle V2 comes into the in-parallel travel state with the own vehicle V1 during an operation of the LKA function, the target course of the own vehicle V1 is offset to a side of separating from the other vehicle V2.SELECTED DRAWING: Figure 3 【課題】車線維持支援機能作動中の自車両と他車両とが横並びになる際のドライバの不安を払拭できる、運転支援装置を提供する。【解決手段】ＬＫＡ機能により、自車両Ｖ１が走行チュの車線の中央に目標進路が設定される。そして、車両Ｖ１が目標進路を走行するように、ステアリング制御が行われる。ＬＫＡ機能の作動中に、他車両Ｖ２が検出されて、その他車両Ｖ２が自車両Ｖ１と横並びになると判断される場合、自車両Ｖ１の目標進路が他車両Ｖ２から離れる側にオフセットされる。【選択図】図３
