Fan control rework (thermald → 4Hz):
- DT_TRML 0.5s → 0.25s (thermald loop + fan PID now at 4Hz)
- New clamp rules based on (gear, cruise_engaged, standstill):
parked → 0-100%
in drive + cruise engaged (any speed) → 30-100%
in drive + cruise off + standstill → 10-100%
in drive + cruise off + moving → 30-100%
- thermald now reads gearShifter (via carState) and controlsState.enabled,
passes them to fan_controller.update()
- Removed BENCH_MODE special case — new rules cover bench automatically
- Removed ignition-based branches — gear is the correct signal
System health overlay:
- Subscribed UI to peripheralState so we can read fanSpeedRpm
- Added FAN row: actual fan% (RPM / 65) to sit alongside LAG/DROP/TEMP/CPU/MEM.
Shows the real fan output vs. what the PID is asking for.
Migrate hot signals from paramsMemory to cereal (frogpilotCarControl):
- Added latRequested @3 and noLatLaneChange @4 to FrogPilotCarControl schema
- controlsd sets FPCC.latRequested / FPCC.noLatLaneChange (send-on-change
already gates the IPC)
- modeld reads from sm['frogpilotCarControl'] (added to its subscribers)
instead of paramsMemory (saves ~20 file-read syscalls/sec)
- carcontroller reads from frogpilot_variables (set in-process by controlsd)
instead of paramsMemory (saves ~100 file-read syscalls/sec in 100Hz path).
Dropped carcontroller's now-unused Params instance and import.
- UI (ui.cc, onroad.cc) reads from sm['frogpilotCarControl'].noLatLaneChange
- Removed LatRequested and no_lat_lane_change param registrations + defaults

- Fan controller: allow full 100% fan when offroad temp >= 75°C (startup cooling)
- ModelFps memory param: modeld publishes actual FPS (20 or 4) so downstream
consumers can adjust frame-rate-dependent logic
- Longitudinal planner: dynamically adjusts dt and v_desired_filter based on
ModelFps; FCW crash_cnt threshold scales with FPS to maintain consistent
0.15s trigger window at both 20fps and 4fps
- controlsd: suppress commIssue alerts for 2s after lateral control engages
(FPS transition from 4->20 causes transient freq check failures)
- Shutdown timer: hardcoded to 10 minutes (was 45min via FrogPilot param),
screen taps reset the countdown via ShutdownTouchReset memory param,
removed Shutdown Timer UI selector from ClearPilot menu

Standstill quiet mode was clamped to 0-10% which is dangerously low
under sustained load. Raised to 0-30%. Bench mode now forces 30-100%
onroad fan range regardless of standstill to prevent overheating
during bench testing.

- modeld: enter standby when latActive=false (not just standstill),
exception for lane changes (no_lat_lane_change). Fix Python capnp
property access (.latActive not getLatActive())
- controlsd: move model_suppress computation early, suppress radarFault,
posenetInvalid, locationdTemporaryError, paramsdTemporaryError during
model standby + 2s grace period. All cascade from modeld not publishing
- dashcamd: always_run (manages own trip lifecycle), wait for valid frame
dimensions before encoding (fix SIGSEGV on early start)
- Fan: driving range 15-100% (was 30-100%)
