rss_longitudinal_same — DRIVE rss op

• Data kinds: table → scalar

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

Usage

Minimum safe distance [m] in the same direction (paper Lemma 2 / lib calculateSafeLongitudinalDistanceSameDirection).

> The detailed description below is the original text — the summary and the headings are translated.

d_min = [ v_r ρ + ½ a ρ² + (v_r + a ρ)²/(2 b_min) − v_f²/(2 b_max) ]_+ + min_distance。後続車 c_r のパラメータが p(ρ, accel_max, brake_min, v_max_accel, min_distance)、先行車 c_f の brake_max は p_front(None なら p)から取る。v_rear, v_front ≥ 0。
