long_params — DRIVE `long` op

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

• Call: import fullseye as fs; fs.ledger.long_params(mass: 'float' = 1300.0, c_rr: 'float' = 0.012, cda: 'float' = 0.65, rho_air: 'float' = 1.2, a_drive_max: 'float' = 3.0, a_brake_max: 'float' = 6.0, reaction: 'float' = 0.75, mu: 'float' = 0.8, a_creep: 'float' = 0.3, g: 'float' = 9.80665) -> 'Dict[str, float]' (to call the implementation directly, import drivelong; drivelong.long_params(mass: 'float' = 1300.0, c_rr: 'float' = 0.012, cda: 'float' = 0.65, rho_air: 'float' = 1.2, a_drive_max: 'float' = 3.0, a_brake_max: 'float' = 6.0, reaction: 'float' = 0.75, mu: 'float' = 0.8, a_creep: 'float' = 0.3, g: 'float' = 9.80665) -> 'Dict[str, float]'; from the registry, opsdrive.get("long_params"))

縦の運動のパラメータ(既定値はすべて仮定。出典はモジュールの docstring)。

Parameters

----------

mass : 車両質量 [kg] (> 0)。空気抵抗の係数 k = ρ_air C_d A / (2 m) にだけ効く。

c_rr : 転がり抵抗係数(≥ 0、文献値 0.010〜0.015)

cda : C_d × 前面投影面積 [m²] (≥ 0。0 で空気抵抗なし)

rho_air : 空気密度 [kg/m³] (≥ 0)

a_drive_max, a_brake_max : 駆動・制動の上限 [m/s²] (> 0)。実際の上限はさらに μ g cos θ で頭打ち。

reaction : 反応時間(空走)[s] (≥ 0)

mu : 路面とタイヤの摩擦係数(> 0。乾燥 0.7〜0.8・湿潤 0.4〜0.6 —— 要確認)

a_creep : AT のクリープの駆動 [m/s²] (≥ 0。保持の間だけ)

g : 重力加速度 [m/s²] (> 0)

Returns

-------

dict : 引数と同じキー + `k`(空気抵抗の係数 [1/m])。

Raises `ValueError`: 非有限・範囲外。
