Summary:To provide a steering guide torque controller improved to minimize the risk that a driver may feel a steering resistance attributable to a steering guide torque in a situation where the driver performs a steering maneuver to deviate from a lane by correcting the steering guide torque according to the possibility the driver may perform the steering maneuver for lane deviation.SOLUTION: A control unit that controls a reaction force actuator which applies a steering guide torque to a steering wheel computes a target steering guide torque Tsgt, which is used to force a vehicle to travel along a lane, on the basis of information on the lane ahead of a vehicle which is detected by a camera sensor (S50 to S120), corrects the target steering guide torque so that the target steering guide torque will get smaller as the possibility that a driver may perform a steering maneuver to deviate from a lane is higher (S100 to S150), and controls the reaction force actuator so that the steering guide torque will be equal to the target steering guide torque (S160 to S180).SELECTED DRAWING: Figure 3 【課題】ドライバーが車線逸脱の操舵操作を行う可能性に応じて操舵ガイドトルクを修正することによりドライバーが車線逸脱の操舵操作を行う状況において、操舵ガイドトルクに起因する操舵抵抗を感じる虞が低減されるよう改良された操舵ガイドトルク制御装置を提供する。【解決手段】ステアリングホイールに操舵ガイドトルクを付与する反力アクチュエータを制御する制御ユニットは、カメラセンサにより検出された車両の前方の車線の情報に基づいて車両を車線に沿って走行させるための目標操舵ガイドトルクTsgtを演算し(S50~S120)、ドライバーが車線逸脱する操舵操作を行う可能性が高いほど小さくなるように目標操舵ガイドトルクを修正し(S100~S150)、操舵ガイドトルクが目標操舵ガイドトルクになるように反力アクチュエータを制御する(S160~S180)。【選択図】図3
