[jyoung8607]

Checklist

• added entry to CAR in selfdrive/car/*/values.py and ran selfdrive/car/docs.py to generate new docs
• test route added to routes.py
• route with openpilot: TBD
• route with stock system: TBD
• car harness used (if comma doesn't sell it, put N/A): VW_A

To-Do

• FCA Giorgio: Alfa Romeo Stelvio opendbc#1043
• FCA Giorgio: Alfa Romeo Stelvio panda#1980
• UDS/VIN fingerprinting
• Locate gearshift position signal
• Locate driver gas signal
• Locate cruise button signals
• Locate driver seatbelt signal
• Locate BSM signals
• Verify turn signal correctly processed (comfort vs latched, blink vs continuous)
• Plot out and test known HUD messaging (lane lines, etc)

Notes

The good: this platform uses the same Bosch MFK2 camera as earlier Volkswagen. The CAN messaging is entirely different, but we're able to use the VW_A harness unmodified straight from comma's store. So far, it seems to be getting down the road nicely, no apparent EPS lockout.

The not-so-good: the CAN topology seems to keep a lot of powertrain stuff away from the camera. On our first couple RE passes, I haven't been able to locate a CC button message or even a driver gas-press signal. We could maybe discuss NDOG-only operation if we truly can't find driver gas-press, but if we can't cancel-spam to sync ACC engagement state, that's going to be a problem for upstream. Now that we've proven drivability with no EPS lockout, I'll go a little more tryhard on those signals.

Wikipedia thinks the FCA Giorgio platform also covers Alfa Romeo Giulia, certain Maserati, and newer Jeep Grand Cherokee, but we won't be able to verify that without individual testing.
