hill_start_command — DRIVE long op

• Data kinds: scalar × scalar × scalar × scalar → any

• Call: import fullseye as fs; fs.ledger.hill_start_command(t_release: 'float', tau: 'float', a_drive: 'float', b_hold: 'float', a_creep: 'float' = 0.0, technique: 'str' = 'gap', v_cruise: 'Optional[float]' = None) -> 'Callable' (to call the implementation directly, import drivelong; drivelong.hill_start_command(t_release: 'float', tau: 'float', a_drive: 'float', b_hold: 'float', a_creep: 'float' = 0.0, technique: 'str' = 'gap', v_cruise: 'Optional[float]' = None) -> 'Callable'; from the registry, opsdrive.get("hill_start_command"))

Usage

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

坂道発進の指令。t_release までは保持(クリープ + 制動 b_hold)。

• `technique="gap"`: t_release でブレーキを離し、τ 後に駆動 a_drive(足を踏み替える間 = ずり下がる。閉形式は

:func:hill_start_rollback)。

• `technique="overlap"`: t_release から τ の間、ブレーキを保ったままアクセルを踏み(駆動 a_drive)、τ 後にブレーキを離す

(教習で教える「アクセルを踏んでからブレーキを離す」)。駆動 > 坂なら逆行 0。

`v_cruise` を与えると、その速さに達したら駆動を止める(惰行)。
