PROBLEM TO BE SOLVED: To provide a drive support device which can set a correction amount of a steering angle command value to a further proper value corresponding to an intention of a user, in the drive support device which performs processing for correcting the steering angle command value in order to make a vehicle travel along a lane.SOLUTION: In a steering angle command value setting processing part M14, a steering angle command value θp1* is set on the basis of input torque (steering torque Trqs) inputted to a steering wheel. In a support amount calculation processing part M16, a support correction amount Δθp1* being a correction amount of the steering angle command value θp1* for performing a lane keep assist is calculated. In a gain calculation processing part M18, a gain Gm* is set to a value smaller than that in the case that consistency of steering by the support amount calculation processing part M16, and steering by a user is low compared with the case that the consistency is high on the basis of the steering torque Trqs and a steering angle θp. The steering angle command value θp1* is corrected by a value in which the support correction amount Δθp1* is corrected by the gain Gm*.SELECTED DRAWING: Figure 2 【課題】車両を車線に沿って走行させるために転舵角指令値を補正する処理を実行するものにおいて、転舵角指令値の補正量をユーザの意思に応じたより適切な値にできるようにした運転支援装置を提供する。【解決手段】転舵角指令値設定処理部Ｍ１４では、ステアリングに対する入力トルク（操舵トルクＴｒｑｓ）に基づき、転舵角指令値θｐ１＊を設定する。支援量算出処理部Ｍ１６では、レーンキープアシストを実行するための転舵角指令値θｐ１＊の補正量である支援補正量Δθｐ１＊を算出する。ゲイン算出処理部Ｍ１８では、操舵トルクＴｒｑｓと転舵角θｐとに基づき、支援量算出処理部Ｍ１６による操舵と、ユーザによる操舵との整合性が低い場合に高い場合よりもゲインＧｍ＊を小さい値とする。支援補正量Δθｐ１＊がゲインＧｍ＊にて補正された値によって転舵角指令値θｐ１＊が補正される。【選択図】図２
