Using openpilot in a car

To use openpilot in a car, you need four things:

  1. Supported Device: a comma four, available at comma.ai/shop/comma-four.
  2. Software: The setup procedure for the comma four allows users to enter a URL for custom software. Use the URL openpilot.comma.ai to install the release version.
  3. Supported Car: Ensure that you have one of the 300+ supported cars.
  4. Car Harness: You will also need a car harness to connect your comma four to your car.

We have detailed instructions for how to install the harness and device in a car. Note that it's possible to run openpilot on other hardware, although it's not plug-and-play.

Branches

Running master and other branches directly is supported, but it's recommended to run one of the following prebuilt branches:

comma four branch comma 3X branch URL description
release-mici release-tizi openpilot.comma.ai This is openpilot's release branch.
release-mici-staging release-tizi-staging openpilot-test.comma.ai This is the staging branch for releases. Use it to get new releases slightly early.
nightly nightly openpilot-nightly.comma.ai This is the bleeding edge development branch. Do not expect this to be stable.
nightly-dev nightly-dev installer.comma.ai/commaai/nightly-dev Same as nightly, but includes experimental development features for some cars.

For chestnut, use the following installer URLs:

branch URL description
release-chestnut installer.comma.ai/commaai/release-chestnut This is openpilot's release branch.
release-chestnut-staging installer.comma.ai/commaai/release-chestnut-staging This is the staging branch for releases. Use it to get new releases slightly early.
nightly-chestnut installer.comma.ai/commaai/nightly-chestnut This is the bleeding edge development branch. Do not expect this to be stable.
nightly-chestnut-dev installer.comma.ai/commaai/nightly-chestnut-dev Same as nightly, but includes experimental development features for some cars.

Safety and Testing

  • openpilot observes ISO26262 guidelines, see SAFETY.md for more details.
  • openpilot has software-in-the-loop tests that run on every commit.
  • The code enforcing the safety model lives in panda and is written in C, see code rigor for more details.
  • panda has software-in-the-loop safety tests.
  • Internally, we have a hardware-in-the-loop Jenkins test suite that builds and unit tests the various processes.
  • panda has additional hardware-in-the-loop tests.
  • We run the latest openpilot in a testing closet containing 10 comma devices continuously replaying routes.

User Data and comma Account

By default, openpilot uploads driving data to our servers. You can also access your data through comma connect. We use your data to train better models and improve openpilot for everyone.

openpilot is open source software, and users can disable data collection if they wish.

openpilot logs the road-facing cameras, CAN, GPS, IMU, magnetometer, thermal sensors, crashes, and operating system logs. The driver-facing camera and microphone are only logged if you explicitly opt-in in settings.

By using openpilot, you agree to our Privacy Policy. You understand that use of this software or its related services will generate certain types of user data, which may be logged and stored at the sole discretion of comma. By accepting this agreement, you grant an irrevocable, perpetual, worldwide right to comma for the use of this data.
