Known affected car model:

The issue seems not car specific, but we have seen many Hondas with the same issue. So far, it has been confirmed in Odyssey, Ridgeline, and Pilot. It is also possible that Honda is the most common car brand to use a comma pedal.

Issue:

OP disengages randomly, or OP disengages immediately after enable.

Current fix:

Code change on selfdrive/car/honda/carstate.py, increase ret.gasPressed = ret.gas > from 0 to 20.

&

Code change on panda/board/safety/safety_honda.h, increase const int HONDA_GAS_INTERCEPTOR_THRESHOLD = from 492 to 15000; then flash panda: https://github.com/commaai/openpilot/wiki/Panda-Flashing, be sure to pkill -f boardd && pkill -f openpilot first, then sudo reboot.

If you want to try the current fix, you can try the following branch

EON Gold, C2:

  • Based off Aragon 0.8.10-model-0.8.9-release-honda
  • git clone --branch Pedal-fix_aragon_089 https://github.com/fraserxiong/openpilot.git
  • https://smiskol.com/fork/fraserxiong/Pedal-fix_aragon_089

Future fix:

The signal noise from the gas pedal is unpredictable, so implementing a noise filter will be the best fix.

Fix implementation:

N/A

Other:

If it is possible, I suggest community members to get a new OEM (Honda) gas pedal and change the gas pedal to confirm that their gas pedal is malfunctioning. This issue won't affect the car without OP because the ECU will not react to a small spike, because it has a noise filter.
