rss_worst_case_gap — DRIVE `rss` op

• Data kinds: table → table

• Call: import fullseye as fs; fs.ledger.rss_worst_case_gap(d0: 'float', v_rear: 'float', v_front: 'float', p: 'dict', p_front: 'Optional[dict]' = None, dt: 'float' = 0.001, t_max: 'Optional[float]' = None) -> 'Dict[str, object]' (to call the implementation directly, import rsssafety; rsssafety.rss_worst_case_gap(d0: 'float', v_rear: 'float', v_front: 'float', p: 'dict', p_front: 'Optional[dict]' = None, dt: 'float' = 0.001, t_max: 'Optional[float]' = None) -> 'Dict[str, object]'; from the registry, opsdrive.get("rss_worst_case_gap"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

同方向の最悪ケース(論文 Definition 4)を時間で追う。

先行車は t = 0 から `brake_max で停止まで減速。後続車は ρ の間 accel_max(v_max_accel` で頭打ち)、

その後 `brake_min` で停止まで減速。各時刻の位置は区分ごとの等加速度の厳密式で、時刻列には ρ・頭打ち時刻・

各車の停止時刻を必ず含める(`dt` は表示密度で、min_gap は dt に依らない)。

Returns

-------

dict : `t, x_rear, x_front, v_rear, v_front, gap (ndarray)、min_gap, t_min` (float)、

`collided (min_gap < 0)、t_stop_rear, t_stop_front`。gap = x_front − x_rear

(後続の前端と先行の後端の間隔、後続は x = 0、先行は x = d0 から出発)。

`min_gap = d0 − max(d_min − min_distance, 0) が成り立つ(d_min = rss_longitudinal_same`)。

`t_max` を与えると(両車の停止より前で)打ち切る。
