PROBLEM TO BE SOLVED: To reduce a torque to be given in a direction where a curve is curved to the inside while keeping a torque to be given in a direction where the curve is curved to the outside, in a vehicle equipped with a hydraulic power steering.SOLUTION: A lane keeping supporting device 1 includes: a first supporting section which performs steering support of a vehicle by hydraulic pressure; a second supporting section which performs the steering support of the vehicle by a motor; and a steering supporting control section 83 which, when the vehicle is determined to have entered a curve based on an image obtained by photographing a lane in the front of a travel direction of the vehicle, reduces a steering support amount by the first supporting section, and starts the steering support by the second supporting section.SELECTED DRAWING: Figure 3
【課題】油圧式パワーステアリングを搭載した車両において、カーブの外側に曲がる方向に付与するトルクを維持しつつ、カーブの内側に曲がる方向のトルクの付与を小さくする。【解決手段】車線維持支援装置1は、油圧により車両の操舵補助を行う第1補助部と、モータにより前記車両の操舵補助を行う第2補助部と、前記車両の進行方向前方の車線が撮影された撮影画像に基づいて前記車両がカーブへ進入したと判定した場合に前記第1補助部による操舵補助量を低減するとともに、前記第2補助部による操舵補助を開始させる操舵補助制御部83と、を備える。【選択図】図3
