PROBLEM TO BE SOLVED: To provide a vehicle travel controlling apparatus which prevents excessive closing to a following target vehicle and which may reduce the possibility of providing a potent uncomfortable feeling to a driver in a case where there is a possibility of cut in by another vehicle.SOLUTION: A vehicle travel controlling apparatus acquires object information with a forward radar apparatus, and specifies a following target vehicle based on the object information and expects a probability of cut in by the expected interruptive vehicle. A controlling apparatus calculates target acceleration for keeping following distance from the following target vehicle at a first setting following distance as a following target acceleration and calculates target acceleration for keeping following distance from the expected interruptive vehicle having first threshold or more of interruption probability at a second setting following distance as counter-interruption target acceleration. The controlling apparatus selects a smaller one among the following target acceleration and the counter-interruption target acceleration as a mediated target acceleration and controls driving power and control power of the present vehicle in a manner where actual acceleration of the present vehicle approaches the mediated target acceleration.SELECTED DRAWING: Figure 3
【課題】他車両が割り込んでくる可能性がある場合に、追従対象車両に過剰に接近せず且つ運転者に強い違和感を与える可能性を低下させることができる車両走行制御装置を提供する。【解決手段】車両走行制御装置は、前方レーダ装置を用いて物標情報を取得し、その物標情報に基いて追従対象車両を特定し且つ予想割込み車両の割込み確率を推定する。制御装置は、追従対象車両との車間距離を第1設定車間距離に維持するための目標加速度を追従用目標加速度として演算し、且つ、割込み確率が第1閾値以上である予想割込み車両との車間距離を第2設定車間距離に維持するための目標加速度を割込み対応用目標加速度として演算する。制御装置は、追従用目標加速度及び割込み対応用目標加速度のうちの小さい方を調停後目標加速度として選択し、自車両の実際の加速度が調停後目標加速度に近づくように自車両の駆動力及び制動力を制御する。【選択図】図3
