passing_decision — DRIVE traffic op

• Data kinds: none → any (an op determined by its arguments alone — it takes no image or data input)

• Call: import fullseye as fs; fs.ledger.passing_decision(dist_oncoming: 'float', parked_len: 'float', margin_front: 'float', margin_back: 'float', v_ego: 'float', v_oncoming: 'float', *, lane_change_time: 'float', ego_length: 'float' = 0.0, pet_min: 'float' = 0.0, v_obstacle: 'float' = 0.0) -> 'str' (to call the implementation directly, import drivetraffic; drivetraffic.passing_decision(dist_oncoming: 'float', parked_len: 'float', margin_front: 'float', margin_back: 'float', v_ego: 'float', v_oncoming: 'float', *, lane_change_time: 'float', ego_length: 'float' = 0.0, pet_min: 'float' = 0.0, v_obstacle: 'float' = 0.0) -> 'str'; from the registry, opsdrive.get("passing_decision"))

Usage

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

対向車までの距離 `dist_oncoming`(判断時、自車が x_in にいるとき)で "go" か "wait" を返す。

D ≥ D*(`passing_gap_required の d_required`)なら "go"(境目ちょうどは PET = pet_min で go)。

`dist_oncoming = +inf` は「対向車なし」= "go"(他の引数の検査はする)。−inf・NaN は ValueError。

`v_obstacle > 0 は走っている障害物(passing_gap_required`)。

門: D* ± ε で判断が切り替わる / `passing_simulate` の PET が pet_min になる境目と D* が一致。
