PROBLEM TO BE SOLVED: To reduce drivers' fatigue during turning while performing a lane keeping control.SOLUTION: Assist torque for lane keeping in a direction to avoid a deviation of its own vehicle from a traffic lane is applied at a level within a range drivers can overcome. When a lateral G applied to its own vehicle is equal to or more than a prescribed value set in advance, an increase in the assist torque for lane keeping is suppressed. Suppression of the assist torque for lane keeping is performed, for examples, by such as: gradually reducing a gain for calculating the assist torque for lane keeping in response to an increase in a lateral G; keeping the assist torque for lane keeping at the level when the lateral G became the prescribed value; or limiting the assist torque for lane keeping so that lateral direction friction force M to a seat back 13 of a driver 20 does not become smaller than lateral force Y.

    【課題】車線維持制御を行いつつ旋回中における運転者の疲労を低減する。【解決手段】自車両が走行車線から逸脱するのを防止する方向への車線維持用アシストトルクが、運転者が打ち勝てる範囲の大きさで付与される。自車両に作用する横Gがあらかじめ設定された所定値以上のときに、車線維持用アシストトルクの増大が抑制される。車線維持用アシストトルクの増大抑制として、例えば、車線維持用アシストトルクを演算するゲインを横Gの増大に応じて徐々に低減したり、横Gが所定値となった時点の車線維持用アシストトルクの大きさに保持したり、運転者20のシートバック13に対する横方向摩擦力Mが横力Yよりも小さくならないように車線維持用アシストトルクを制限する等により行われる。【選択図】 図13
