steady_cornering — DRIVE lateral 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.steady_cornering(speed: 'float', radius: 'float', params: 'dict') -> 'Dict[str, float]' (to call the implementation directly, import drivelateral; drivelateral.steady_cornering(speed: 'float', radius: 'float', params: 'dict') -> 'Dict[str, float]'; from the registry, opsdrive.get("steady_cornering"))

Usage

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

線形 2 輪等価モデルの定常円旋回(速さ u、旋回半径 R = u/r、左旋回を正)。

R は前向きの速さ u とヨーレート r で定義する(線形モデルの慣習)。重心の軌跡の実際の半径は合成の速さ / r =

R √(1 + tan²β) で、β が小さい範囲で R に等しい(門で確かめた差は β² の桁)。

返り値: `steer δ = L/R + K u²/R [rad]、yaw_rate r = u/R、lateral_accel` u²/R、

`sideslip β = l_r/R − m l_f u²/(C_r L R)、yaw_gain r/δ = (u/L)/(1 + K u²/L)、front_slip・rear_slip`

(軸の横すべり角)、`K`。R < 0 で右旋回(符号がそのまま反転)。

Raises `ValueError`: u ≤ 0、R = 0 / 非有限、母数の誤り、1 + K u²/L ≤ 0(臨界速度以上)。
