PROBLEM TO BE SOLVED: To provide a vehicle acceleration-deceleration control apparatus capable of smoothly changing the direction and magnitude of inertia force exerted on a vehicle or passenger in the process of entering a curve to exiting it.SOLUTION: A vehicle acceleration-deceleration control apparatus (10) includes: a maximum lateral acceleration obtainment part (12) for obtaining maximum lateral acceleration that a vehicle (1) can generate while turning; a curve form information obtainment part (14) for obtaining form information, including a curvature radius, of a curve existing ahead of the vehicle; a target acceleration-deceleration setup part (16) for setting a target acceleration to be applied to a start point of the curve as deceleration equivalent to the maximum lateral acceleration, setting target deceleration to be applied to a minimum curvature radius point of the curve at zero ("0"), and setting target deceleration to be applied to between the start point of the curve and the minimum curvature radius point thereof so as to decrease from the start point toward the minimum curvature radius point; and an acceleration-deceleration control part (18) for controlling deceleration of the vehicle in its progress direction along the set target deceleration applied when the vehicle travels from the start point of the curve and the minimum curvature radius point thereof.
【課題】カーブへの進入から脱出までの走行過程において、車両や乗員に働く慣性力の方向や大きさを滑らかに変化させることができる車両加減速制御装置を提供する。【解決手段】車両加減速制御装置(10)は、車両(1)が旋回中に発生させることのできる最大横加速度を取得する最大横加速度取得部(12)と、車両の前方に存在するカーブの曲率半径を含む形状情報を取得するカーブ形状情報取得部(14)と、カーブの開始地点における目標減速度を最大横加速度と等しい大きさの減速度に設定し、カーブの曲率半径最小地点における目標減速度を0に設定し、カーブの開始地点と曲率半径最小地点との間の目標減速度を、この開始地点から曲率半径最小地点に向かって減少するように設定する目標加減速度設定部(16)と、車両がカーブの開始地点から曲率半径最小地点まで走行するときに、設定された目標減速度に従って車両の進行方向の減速を制御する加減速制御部(18)とを有する。【選択図】図1
