What is openpilot?
------

[openpilot](http://github.com/commaai/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](docs/CARS.md). In addition, while openpilot is engaged, a camera-based Driver Monitoring (DM) feature alerts distracted and asleep drivers. See more about [the vehicle integration](docs/INTEGRATION.md) and [limitations](docs/LIMITATIONS.md).

Running on a dedicated device in a car
------

To use openpilot in a car, you need four things
1. **Supported Device:** A comma 3/3X. You can purchase these devices from (https://comma.ai/shop/comma-3x)
  
2. **Software:** The setup procedure for the comma 3/3X allows users to enter a URL for custom software.
  To install the release version of openpilot, use the URL `openpilot.comma.ai`.
  To install openpilot master (for more advanced users), use the URL `installer.comma.ai/commaai/master`. You can replace "commaai" with another GitHub username to install a fork.

3. **Supported Car:** Ensure that you have one of [the 250+ supported cars](docs/CARS.md). openpilot supports a wide range of car makes including Honda, Toyota, Hyundai, Nissan, Kia, Chrysler, Lexus, Acura, Audi, VW, Ford, and many more.
  If your car is not officially listed as supported but has adaptive cruise control and lane-keeping assist, it's likely capable of running openpilot.
  
4. **Car Harness:** You will also need a [car harness](https://comma.ai/shop/car-harness) to connect your comma 3/3X to your car.
  We have detailed instructions for [how to install the harness and device in a car](https://comma.ai/setup).

Running on PC
------

All openpilot services can run as usual on a PC without requiring special hardware or a car. You can also run openpilot on recorded or simulated data to develop or experiment with openpilot.

With openpilot's tools, you can plot logs, replay drives, and watch the full-res camera streams. See [the tools README](tools/README.md) for more information.

You can also run openpilot in simulation [with the CARLA simulator](tools/sim/README.md). This allows openpilot to drive around a virtual car on your Ubuntu machine. The whole setup should only take a few minutes but does require a decent GPU.

A PC running openpilot can also control your vehicle if it is connected to a [webcam](https://github.com/commaai/openpilot/tree/master/tools/webcam), a [black panda](https://comma.ai/shop/products/panda), and a [harness](https://comma.ai/shop/products/car-harness).

Community and Contributing
------

openpilot is developed by [comma](https://comma.ai/) and by users like you. We welcome both pull requests and issues on [GitHub](http://github.com/commaai/openpilot). Bug fixes and new car ports are encouraged. Check out [the contributing docs](docs/CONTRIBUTING.md).

Documentation related to openpilot development can be found on [docs.comma.ai](https://docs.comma.ai). Information about running openpilot (e.g. FAQ, fingerprinting, troubleshooting, custom forks, community hardware) should go on the [wiki](https://github.com/commaai/openpilot/wiki).

You can add support for your car by following guides we have written for [Brand](https://blog.comma.ai/how-to-write-a-car-port-for-openpilot/) and [Model](https://blog.comma.ai/openpilot-port-guide-for-toyota-models/) ports. Generally, a car with adaptive cruise control and lane keep assist is a good candidate. [Join our Discord](https://discord.comma.ai) 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](https://connect.comma.ai/). 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 cameras, 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](https://comma.ai/privacy). 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](docs/SAFETY.md) for more details.
* openpilot has software-in-the-loop [tests](.github/workflows/selfdrive_tests.yaml) that run on every commit.
* The code enforcing the safety model lives in panda and is written in C, see [code rigor](https://github.com/commaai/panda#code-rigor) for more details.
* panda has software-in-the-loop [safety tests](https://github.com/commaai/panda/tree/master/tests/safety).
* 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](https://github.com/commaai/panda/blob/master/Jenkinsfile).
* We run the latest openpilot in a testing closet containing 10 comma devices continuously replaying routes.
