This is a StarPilot adapter to the September 2026 proposed library shape.
|

It is not a released BluePilot library, tag, or claim of BluePilot validation.
|

The existing curvature controller remains StarPilot-owned. Pinion curvature,
|

curvature-primary settings and the unsafe native reset bypass are not imported.

`5eedebd79e99493624f9d6af0750d1dd5713306c`). Alan Polk authored the initial

trim, model-position fallback, correction slew and default-strength changes;
|

ghbarker contributed reference/NaN guards and tests. The source explicitly credits
|
||||
StarPilot/u/jc01rho for curvature-domain placement/geometry. The core adaptation
|
||||
adds immutable host projection and conservative stale/driver-pressure suppression.

# BluePilot Ford angle control
|
||||
|
||||
StarPilot adaptation of BluePilotDev/bluepilot `bp-7.0`, pinned to
|
||||
[e1d051d7ba270261b4455068bd68f1a58db15a4a](https://github.com/BluePilotDev/bluepilot/commit/e1d051d7ba270261b4455068bd68f1a58db15a4a).
|
||||
The layout follows Alan Polk's September 2026 library proposal. This is an
|
||||
adaptation, not an upstream library release.
|
||||
|
||||
Existing curvature control remains the default. Explicit `FordLateralMode=1`
|
||||
selects angle control next drive; the saved choice persists when unavailable.
|
||||
Only this selector is exposed. Fixed defaults and bounds live in
|
||||
`params/manifest.json`; pinion-yaw correction and curvature-primary tuning are
|
||||
outside this library. Angle lane-centering trim is available as a default-disabled
|
||||
core capability, separately sourced from BluePilot bp-dev
|
||||
`e22afa6be9b881fa784c92ebb316db47728a3d81`; it adds no public settings.
|
||||
|
||||
`core/` accepts scalar/model inputs without openpilot, Params or messaging
|
||||
imports. `can/` owns encoding, `safety/ford_bp.h` owns native enforcement, and
|
||||
`hosts/starpilot.py` connects the host. `params/protocol.json` generates the wire
|
||||
constants. The folder is vendored without submodules, LFS or an external runtime.
|
||||
|
||||
## Admission
|
||||
|
||||
Classic: Bronco Sport Mk1, Escape Mk4, Focus Mk4, Maverick Mk1, Explorer Mk6.
|
||||
CAN FD: Escape Mk4.5, Expedition Mk4, F150 Mk14, F150 Lightning Mk1, Ranger Mk2,
|
||||
Mustang Mach-E Mk1.
|
||||
|
||||
Exact classic safety parameters 32/33 map to angle 128/129; CAN FD 18/19 and
|
||||
66/67 map to 130/131. Parameter 131 requires DEBUG; RELEASE retains stock 130.
|
||||
Longitudinal, radar, fingerprint and parser policy remain host-owned. Admission
|
||||
uses the final CarParams contract, not brand or steering-control enum alone.
|
||||
|
||||
AOL, alternative experiences, Transit, Edge, Mondeo, SecOC, passive, dashcam,
|
||||
notCar and unsupported static flags are excluded. Auxiliary noOutput requires
|
||||
parameter zero; production deployments with two Pandas remain unqualified until
|
||||
actual startup, bus routing and public acknowledgments are verified.
|
||||
|
||||
## Safety design
|
||||
|
||||
The extension uses small Ford hooks without changing shared safety headers or
|
||||
existing curvature namespaces. Active steering requires ordinary controls
|
||||
permission, healthy physical RX and a fresh matching public Panda acknowledgment
|
||||
of safety parameter, alternative experience, controls, RX validity, heartbeat and
|
||||
faults. Cruise, gas/brake, checksum, counter, quality and freshness checks apply.
|
||||
Neutral mode cannot grant permission.
|
||||
|
||||
The BluePilot reset-bypass latch is omitted. Rejected frames preserve accepted
|
||||
actuator history and withdraw the shadow lease; accepted neutral commands or
|
||||
permission withdrawal reset history. Lost counters recover through neutral
|
||||
resynchronization. Version or checksum failure cannot fall through to curvature
|
||||
control.
|
||||
|
||||
Active frames carry neutral curvature, offset and curvature rate, with checked
|
||||
mode, ramp, precision, path angle, counter, checksum and cadence. Native enforcement
|
||||
checks the shadow against the actual path across gains 0.95–1.3, bounds both by
|
||||
`min(0.02, 2.4114/v²)`, and bounds the full actual-curvature interval against
|
||||
measured curvature above 10 m/s. Actual path also obeys the 3.5886 m/s³ equivalent
|
||||
jerk limit and rolling message-rate limit. Core quantization and timing margins
|
||||
keep packed commands inside these bounds; an impossible intersection is neutral.
|
||||
|
||||
The versioned 0x3CA announcement preserves StarPilot's existing byte 4 bit 1
|
||||
curvature flag and requires it clear in angle mode. It carries a counter, signed
|
||||
shadow curvature, protocol version and checksum; its lease expires after 60 ms.
|
||||
The shadow derives from the final path after rate limiting and saturation.
|
||||
|
||||
Control computes at 20 Hz, announces through 33 Hz LKA, then sends the latest
|
||||
announced result at 20 Hz, adding at most one steering tick. Permission withdrawal
|
||||
sends neutral immediately. Human-turn recovery uses bounded neutral blips without
|
||||
a native bypass. The retained Dom factory steering delay is 0.22 s; pinned
|
||||
BluePilot uses 0.20 s.
|
||||
|
||||
These stricter native limits and versioned metadata intentionally differ from
|
||||
BluePilot 7.0. Identical bytes or safety decisions are not claimed for affected
|
||||
commands. Runtime and physical ECU qualification remain pending.

BluePilot: Ford CAN-FD path-angle–primary lateral control (developer).

Steering intent is c1 from κ → θ. Converts planner/model curvature into ``path_angle`` using
|
||||
PSCM short lookahead d_ref and y ≈ ½κ x² ⇒ path_angle = ½ κ d_ref (see
|
||||
``bluepilot/agent_info/20_FORD_PSCM_KNOWLEDGE_PACK.md``). Predicted curvature (modelV2) is
|
||||
blended with ``actuators.curvature`` per ``FordPathAngleBlendRatio`` (0 = planner only,
|
||||
1 = model only).
|
||||
|

**c0 (path_offset) is always zero on the wire, unconditionally.** Angle mode has no centering
|
||||
trim -- an earlier port attempt piped a small additive trim onto path_angle through the
|
||||
curv-mode ``LC_PID_controller``, but it never actually tracked lane center correctly in this
|
||||
mode and was removed; only the DBC-required zero c0 remains.
|

|

**Human-turn override**: while the driver manually turns (same sustained-press + angle criteria
|
||||
as ``lateral_curv_ext``, via the shared ``HumanTurnDetector``), lateral is forced inactive (mode
|
||||
0, all-zero signals) instead of winding path_angle into a stale command the PSCM has to reconcile
|
||||
on release -- on the Mach-E's PSCM that reconciliation cost 2-3 s of dead time before control
|
||||
resumed. Mode 0 is panda-clean by construction: every ford.h check has a legitimate
|
||||
!steer_control_enabled branch, so no reset-bypass latch involvement. On release, path_angle ramps
|
||||
back in from zero through the soft ROC below (no jump seed) -- generous at human-turn speeds, and
|
||||
admitted by ford.h's path_angle ROC check (2% looser) without any bypass.

BluePilot: angle-mode "advanced lane positioning" -- a curvature-domain trim toward true
|
||||
lane-line center (plus an optional user left/right bias), for use with path_angle-primary
|
||||
control (``lateral_angle_ext.py``).
|
||||
|
||||
Under curvature-primary control, lane positioning rode on a second DBC signal (path_angle as
|
||||
a heading trim, c3) layered on top of curvature (c1, the primary). In angle mode, path_angle
|
||||
IS the primary signal -- there is no separate trim slot on the wire. An earlier attempt ported
|
||||
the old PID controller as an additive delta on the *final* path_angle value and it never tracked
|
||||
lane center correctly: path_angle there is a derived quantity (``kappa_cmd * v_ego *
|
||||
curvature_factor``), so an additive trim in that domain has the wrong (inverted) speed-dependence
|
||||
for a lane-centering nudge, and it bypasses every limiter angle mode already applies to
|
||||
``kappa_cmd`` (deviation clip, PSCM-saturation clamp, DBC clip, soft ROC).
|
||||
|
||||
This class instead computes a small correction in the **curvature domain**, meant to be added to
|
||||
``kappa_cmd`` before any of those limiters run -- so the correction automatically inherits all of
|
||||
them, with no new safety-relevant code path. This mirrors where a GM-focused fork (StarPilot,
|
||||
u/jc01rho -- ``selfdrive/controls/lib/drive_helpers.py::LaneCenteringController`` on
|
||||
``feat/lane-centering-camera-offset``) places their own lane-centering trim: on the universal
|
||||
``desired_curvature`` signal, upstream of any car-specific actuator conversion. The geometry here
|
||||
(``raw_correction = 2*error / lookahead**2``) is the same ``y ~= 1/2 * kappa * x**2`` relation
|
||||
BluePilot already uses for PSCM d_ref / path_angle elsewhere in this package, solved for the
|
||||
curvature that would eliminate a lateral position error at the lookahead distance.
|
||||
|
||||
**Model-position fallback (blend, not hard gate)**: mirrors ``lateral_curv_ext.py``'s
|
||||
``path_offset`` blend of ``path_offset_position`` (the model's own predicted path -- a "no
|
||||
correction" baseline) vs. ``path_offset_lanelines`` (the geometric lane center), weighted by a
|
||||
laneline confidence score. The *target* we correct toward is that same blend here, so:
|
||||
|
||||
- Good lane lines (confidence -> 1): target -> lane-line center + offset (full centering + bias).
|
||||
- No/poor lane lines (confidence -> 0): target -> the model's own current path + offset, i.e. the
|
||||
correction reduces to *just* the user's left/right bias riding on top of whatever the model
|
||||
already wants to do -- it never goes to zero just because lane lines dropped out. This is the
|
||||
case that matters on center-stripe-only roads with a curbed edge: there's no reliable lane line
|
||||
to center between, but the user's bias should still nudge the car off the curb.
|
||||
|
||||
Confidence uses the exact formula and breakpoints ``lateral_curv_ext.py`` already uses for
|
||||
``laneline_confidence`` / ``min_laneline_confidence_bp`` (smooth width-tolerance + laneline probs,
|
||||
not a hard cutoff) -- reusing an already-tuned, production formula instead of inventing a second one.
