PROBLEM TO BE SOLVED: To switch reaction control according to an increase or decrease in steering input, in a vehicle using a steer-by-wire system.SOLUTION: In a vehicle in which a steering wheel that receives steering input from a driver and a turning wheel that changes the direction of a vehicle are mechanically separated, steering reaction torque corresponding to a traveling state of the vehicle is applied to the steering wheel, thereby exerting vehicular lane sustentation control. At this time, as processing for obtaining a steering reaction torque corresponding to a traveling state of the vehicle, first processing for obtaining steering reaction torque when the vehicle approaches a direction in which the vehicle deviates from a lane and second processing in which steering reaction torque is obtained when the vehicle approaches a direction in which the vehicle avoids deviation from a lane, can separately be performed. In addition, when the traveling state of the vehicle are identical, steering reaction torque obtained by the first processing is greater than steering reaction torque obtained by the second processing.SELECTED DRAWING: Figure 15

    【課題】ステアバイワイヤシステムを用いた車両において、操舵入力の切り増し又は切り戻しに応じて反力制御を切り替える。【解決手段】運転者の操舵入力を受けるステアリングホイールと車両の向きを変える転舵輪とが機械的に切り離された車両において、車両の走行状況に応じた操舵反力トルクをステアリングホイールに付与することで、車両の車線維持制御を行う。このとき、車両の走行状況に応じた操舵反力トルクを求める処理として、車両が車線の逸脱方向に近づく際に操舵反力トルクを求める第1処理と、車両が車線の逸脱回避方向に近づく際に操舵反力トルクを求める第2処理と、を別々に実施可能となっている。また、車両の走行状況が同一のとき、第1処理により求められる操舵反力トルクのほうが、第2処理により求められる操舵反力トルクよりも大きい。【選択図】図15
