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).
To start using openpilot in a car
------
To use openpilot in a car, you need four things:
1. **Supported Device:** a comma 3/3X, available at [comma.ai/shop](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. Use the URL `openpilot.comma.ai` to install the release version.
3. **Supported Car:** Ensure that you have one of [the 250+ supported cars](docs/CARS.md).
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). Note that it's possible to run openpilot on [other hardware](https://blog.comma.ai/self-driving-car-for-free/), although it's not plug-and-play.
To start developing openpilot
------
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).

Safety and Testing
----
* openpilot observes [ISO26262](https://en.wikipedia.org/wiki/ISO_26262) 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.
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.
