sight_stop_speed — DRIVE `env` op

• Data kinds: scalar × scalar × scalar → scalar

• Call: import fullseye as fs; fs.ledger.sight_stop_speed(sight: 'float', reaction: 'float', brake: 'float', theta: 'float' = 0.0, c_rr: 'float' = 0.0, k: 'float' = 0.0, g: 'float' = 9.80665) -> 'float' (to call the implementation directly, import driveenv; driveenv.sight_stop_speed(sight: 'float', reaction: 'float', brake: 'float', theta: 'float' = 0.0, c_rr: 'float' = 0.0, k: 'float' = 0.0, g: 'float' = 9.80665) -> 'float'; from the registry, opsdrive.get("sight_stop_speed"))

Usage

Maximum speed v* at which the car can stop within the visible distance sight: drivelong.stopping_distance_grade(v*) = sight.

k = 0 では v ρ + v²/(2A) = D の正の根 v* = A (√(ρ² + 2D/A) − ρ)(A = brake + g sin θ + c_rr g cos θ)。k > 0 は停止距離が v に単調なので二分法(1e-12)。A ≤ 0(下りで制動が負ける)なら 0。
