To determine the best driving trajectory in an autonomous driving vehicle.SOLUTION: In one embodiment, in response to detecting an obstacle on the basis of a driving environment surrounding an autonomous driving vehicle (ADV), a system projects the obstacle onto a station-time (ST) graph, where the ST graph indicates a location of the obstacle relative to a current location of the ADV at different points in time. The system determines a first set of end points that are not overlapped with the obstacle within the ST graph, where each of the end points of the first set represents a possible end condition. The system generates a first set of trajectory candidates between a starting point representing the current location of the ADV and the end points of the first set on the basis of the ST graph. The system selects one of the trajectory candidates from the first set using a predetermined trajectory selection algorithm to control the ADV in view of the obstacle.SELECTED DRAWING: Figure 7

    【課題】自動運転車において、最善の運転軌道を決定する。【解決手段】一実施形態において、自動運転車両(ADV)の周囲の運転環境に基づいて障害物が検出されたことに応じて、システムは、障害物を停留所−時間(ST)グラフに投影し、STグラフは、異なる時点におけるADVの現在位置に対する障害物の位置を示す。システムは、STグラフにおける障害物と重ならない終端点の第一セットを決定し、第一セットにおける終端点のそれぞれは、可能な終端状況を示す。システムは、STグラフに基づいて、ADVの現在位置を示す開始点と第一セットにおける終端点との間の軌道候補の第一セットを生成する。システムは、予め規定された軌道選択アルゴリズムにより第一セットから軌道候補における1つを選択して、障害物に応じてADVを制御する。【選択図】図7
