What is openpilot?

openpilot is an open source driver assistance system. Currently, openpilot performs the functions of Adaptive Cruise Control (ACC), Automated Lane Centering (ALC), Forward Collision Warning (FCW) and Lane Departure Warning (LDW) for a growing variety of supported car makes, models and model years. In addition, while openpilot is engaged, a camera based Driver Monitoring (DM) feature alerts distracted and asleep drivers. See more about the vehicle integration and limitations here.

Running in a car

To use openpilot in a car, you need four things

• This software. It's free and available right here.
• One of the 140+ supported cars. We support Honda, Toyota, Hyundai, Nissan, Kia, Chrysler, Lexus, Acura, Audi, VW, and more. If your car is not supported, but has adaptive cruise control and lane keeping assist, it's likely able to run openpilot.
• A supported device to run this software. This can be a comma two, comma three, or if you like to experiment, a Ubuntu computer with webcams.
• A way to connect to your car. With a comma two or three, you need only a car harness. With an EON Gold or PC, you also need a black panda.

We have detailed instructions for how to install the device in a car.

Running on PC

To run and develop openpilot, you do not need a car or any special hardware.

The easiest way to get started is with the CARLA simulator. This allows openpilot to drive around a virtual car on your Ubuntu machine. The whole setup should only take a few minutes.

You can also plot logs from a device and replay a drive. See the tools README for more information.

Community and Contributing

openpilot is developed by comma and by users like you. We welcome both pull requests and issues on GitHub. Bug fixes and new car ports are encouraged. Check out the contributing docs.

You can add support for your car by following guides we have written for Brand and Model ports. Generally, a car with adaptive cruise control and lane keep assist is a good candidate. Join our Discord to discuss car ports: most car makes have a dedicated channel.

User Data and comma Account

By default, openpilot uploads the 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: the user is free to disable data collection if they wish to do so.

openpilot logs the road facing camera, CAN, GPS, IMU, magnetometer, thermal sensors, crashes, and operating system logs. The driver facing camera is only logged if you explicitly opt-in in settings. The microphone is not recorded.

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.

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.
