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"))
Advances the kinematic single-track (KS) model by dt with RK4 under a piecewise-constant input u = (δ̇, a). Reference point = center of the rear axle.
state = (x_rear, y_rear, δ, v, ψ). Equations: ẋ = v cos ψ, ẏ = v sin ψ, δ̇ = u₀, v̇ = u₁, ψ̇ = v / l_wb · tan δ (commonroad-vehicle-models vehicle_dynamics_ks; the input saturation steering_constraints / acceleration_constraints is also the same).
Gates: with δ = 0, x = x₀ + v t (1e-9); with constant δ, a circle of radius l_wb / tan δ (back to the start after one lap, 1e-6); if commonroad-io is available, agrees with the odeint of vehicle_dynamics_ks to 1e-6 over 1 step.
Raises ValueError: state not (5,) or non-finite, u not (2,), dt ≤ 0, invalid params.
