ks_step — DRIVE commonroad op

• Data kinds: any × any → any

• Call: import fullseye as fs; fs.ledger.ks_step(state, u, dt: 'float', params=None) -> 'np.ndarray' (to call the implementation directly, import drivecommonroad; drivecommonroad.ks_step(state, u, dt: 'float', params=None) -> 'np.ndarray'; from the registry, opsdrive.get("ks_step"))

Usage

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

運動学単線(KS)モデルを区分一定入力 u = (δ̇, a) で dt だけ RK4 で進める。参照点 = 後軸中心。

state = (x_rear, y_rear, δ, v, ψ)。式: ẋ = v cos ψ、ẏ = v sin ψ、δ̇ = u₀、v̇ = u₁、ψ̇ = v / l_wb · tan δ

(commonroad-vehicle-models `vehicle_dynamics_ks、入力の飽和 steering_constraints / acceleration_constraints` も同じ)。

門: δ = 0 で x = x₀ + v t(1e-9)、一定 δ で半径 l_wb / tan δ の円(1 周で始点へ 1e-6)、commonroad-io があれば

`vehicle_dynamics_ks` の odeint と 1 step で 1e-6 一致。

Raises `ValueError`: state が (5,) でない・非有限、u が (2,) でない、dt ≤ 0、params が不正。
