PROBLEM TO BE SOLVED: To avoid causing a driver to feel discomfort as much as possible when temporary release of acceleration/deceleration control of his/her own vehicle is reset.SOLUTION: A command operation part 20 is configured to determine target speeds at respective points on a road in front of a subject vehicle on the basis of a road shape in front of the vehicle and a current position of the vehicle, and when calculating a forward/backward drive command value to be generated in the vehicle on the basis of the target speeds and the current speed of the vehicle, to adjust the drive command value using an acceleration limit value to limit an acceleration of the vehicle, or a jerk limit value to limit a jerk of the vehicle. An output control part 30 is configured to control an output of the drive command value on the basis of one or more inputs from at least one of a driver's operation of the vehicle and other control systems in the vehicle, so as to temporarily make at least one of values of the acceleration limit value, the jerk value and the drive command value small, when the output of the drive command value is restarted after the stop thereof.SELECTED DRAWING: Figure 4
【課題】自車両の加減速制御が一時的に解除された後に復帰するに際して、運転者になるべく違和感を与えないようにする。【解決手段】指令演算部20は、自車両前方の道路形状および自車両の現在位置に基づいて、自車両前方の道路上の各地点における目標速度を算出し、この目標速度および自車両の現在速度に基づいて、自車両に発生させる前後方向の駆動指令値を演算する際に、自車両の加速度を制限する加速制限値、又は自車両の加加速度を制限する加加速制限値を用いて前記駆動指令値を調整するように構成される。出力制御部30は、自車両の運転者の操作および自車両における他の制御システムのうちの少なくとも一方による入力に基づいて、駆動指令値の出力を制御することにより、駆動指令値の出力を停止させた後に再開させる際に、加速制限値、加加速制限値および駆動指令値のうちの少なくとも一つの値を一時的に小さくするように構成される。【選択図】図4
