rss_longitudinal_check — DRIVE `rss` op

• Data kinds: table → table

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

Usage

Whether the same-direction longitudinal gap d (front of the following vehicle to rear of the lead vehicle, ≥ 0) is safe.

Returns {"safe_distance", "dangerous" (d ≤ safe_distance), "margin" (d − safe_distance)}。
