To provide a vehicle steering support device that can automatically and appropriately change the magnitude of steering guide torque without making a driver feel uncomfortable.SOLUTION: In a vehicle steering support device, a steering support ECU calculates a target steering angle θt for allowing a vehicle to travel along a traveling road, calculates target steering guide torque Tsgt by which steering of a driver is guided such that an actual steering angle θ becomes the target steering angle, and controls a torque application device such that steering guide torque becomes the target steering guide torque. The steering support ECU acquires at least one of information on traveling environments of the vehicle and information on a state of the driver, calculates an index value Ka that indicates a need of the steering guide torque based on at least one information, and corrects the target steering guide torque based on the index value such that the target steering guide torque increases as the need of the steering guide torque is higher.SELECTED DRAWING: Figure 2
【課題】ドライバが煩わしさを覚えることなく操舵ガイドトルクの大きさを自動的に適宜変化させることができる車両用操舵支援装置を提供する。【解決手段】操舵支援ECUが、車両を走行路に沿って走行させるための目標操舵角θtを演算し、実際の操舵角θが目標操舵角になるようにドライバの操舵をガイドする目標操舵ガイドトルクTsgtを演算し、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トルク付与装置を制御する車両用操舵支援装置であって、操舵支援ECUは、車両の走行環境の情報及びドライバの状態についての情報の少なくとも一方を取得し、少なくとも一方の情報に基づいて操舵ガイドトルクの必要性を示す指標値Kaを演算し、操舵ガイドトルクの必要性が高いほど目標操舵ガイドトルクが大きくなるように、指標値に基づいて目標操舵ガイドトルクを修正する。【選択図】図2
