PROBLEM TO BE SOLVED: To provide a vehicular steering device that when traveling road recognizing means erroneously recognizes a traveling road, starts operation of steering control and can prevent the steering control from being wrongly operated according to a state of the erroneously recognized traveling road, and when switching between presence and absence of recognition of the traveling road by the traveling road recognizing means occurs frequently, can prevent the operation of the steering control from being started and stopped frequently.SOLUTION: The vehicular steering device comprises: traveling road recognizing means 21 which recognizes a traveling road on which a vehicle travels and determines reliability on the recognized travelling road or traveling road reliability; target traveling line setting means 22 which sets a target traveling line for the vehicle to travel following the traveling road; steering control means 24 which performs steering control so that the vehicle travels on the target traveling line; and steering control state determining means 23 which operates or stops the steering control on the basis of the traveling road reliability. The steering control state determining means starts operation of the steering control when a state where the traveling road reliability is high is continued for a prescribed time.SELECTED DRAWING: Figure 2
【課題】走行路認識手段が走行路を誤認識した場合に操舵制御の作動を開始し操舵制御が前記誤認識された走行路の状態に応じて誤作動することを防止することができ、また、走行路認識手段による走行路の認識有無の切り替わりが頻発する場合の操舵制御の作動の開始、終了が頻発することを防止することができる。【解決手段】車両が走行する走行路を認識し、認識した走行路の信頼度である走行路信頼度を判定する走行路認識手段21、車両が走行路に追従して走行するための目標走行ラインを設定する目標走行ライン設定手段22、車両が目標走行ラインを走行するように操舵制御を行う操舵制御手段24、および走行路信頼度に基づいて操舵制御を作動あるいは停止する操舵制御状態判定手段23を備え、操舵制御状態判定手段は走行路信頼度が高い状態が所定時間継続した場合に操舵制御の作動を開始する。【選択図】図2
