[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](#supported-cars). In addition, while openpilot is engaged, a camera based Driver Monitoring (DM) feature alerts distracted and asleep drivers.
* Stock Lane Keep Assist (LKA) and stock ALC are replaced by openpilot ALC, which only functions when openpilot is engaged by the user.
* Stock LDW is replaced by openpilot LDW.
Additionally, on specific supported cars (see ACC column in [supported cars](#supported-cars)):
* Stock ACC is replaced by openpilot ACC.
* openpilot FCW operates in addition to stock FCW.
openpilot should preserve all other vehicle's stock features, including, but are not limited to: FCW, Automatic Emergency Braking (AEB), auto high-beam, blind spot warning, and side collision warning.
At the moment, openpilot supports the [EON DevKit](https://comma.ai/shop/products/eon-dashcam-devkit) and the [comma two](https://comma.ai/shop/products/comma-two-devkit). A [car harness](https://comma.ai/shop/products/car-harness) is recommended to connect the EON or comma two to the car. In the future, we'd like to support other platforms as well, like gaming PCs.
<sup>1</sup>Requires a [panda](https://comma.ai/shop/products/panda-obd-ii-dongle) and open sourced [Hyundai giraffe](https://github.com/commaai/neo/tree/master/giraffe/hyundai), designed for the 2019 Sante Fe; pinout may differ for other Hyundai and Kia models. <br/>
<sup>2</sup>28mph for Camry 4CYL L, 4CYL LE and 4CYL SE which don't have Full-Speed Range Dynamic Radar Cruise Control. <br/>
<sup>3</sup>Requires a [custom connector](https://community.comma.ai/wiki/index.php/Volkswagen#Integration_at_R242_Camera) for the [car harness](https://comma.ai/shop/products/car-harness) <br/>
<sup>4</sup>When disconnecting the Driver Support Unit (DSU), openpilot ACC will replace stock ACC. For DSU locations, see [Toyota Wiki page](https://community.comma.ai/wiki/index.php/Toyota). ***NOTE: disconnecting the DSU disables Automatic Emergency Braking (AEB).*** <br/>
<sup>5</sup>[Comma Pedal](https://community.comma.ai/wiki/index.php/Comma_Pedal) is used to provide stop-and-go capability to some of the openpilot-supported cars that don't currently support stop-and-go. Here is how to [build a Comma Pedal](https://medium.com/@jfrux/comma-pedal-building-with-macrofab-6328bea791e8). ***NOTE: The Comma Pedal is not officially supported by [comma](https://comma.ai).*** <br/>
<sup>6</sup>Requires a [panda](https://comma.ai/shop/products/panda-obd-ii-dongle) and [community built giraffe](https://zoneos.com/volt/). ***NOTE: disconnecting the ASCM disables Automatic Emergency Braking (AEB).*** <br/>
Community Maintained Cars and Features are not verified by comma to meet our [safety model](SAFETY.md). Be extra cautious using them. They are only available after enabling the toggle in `Settings->Developer->Enable Community Features`.
Install openpilot on a EON by entering ``https://openpilot.comma.ai`` during the installer setup.
Follow this [video instructions](https://youtu.be/3nlkomHathI) to properly mount the EON on the windshield. Note: openpilot features an automatic pose calibration routine and openpilot performance should not be affected by small pitch and yaw misalignments caused by imprecise EON mounting.
Before placing the device on your windshield, check the state and local laws and ordinances where you drive. Some state laws prohibit or restrict the placement of objects on the windshield of a motor vehicle.
openpilot ALC and openpilot LDW do not automatically drive the vehicle or reduce the amount of attention that must be paid to operate your vehicle. The driver must always keep control of the steering wheel and be ready to correct the openpilot ALC action at all times.
While changing lanes, openpilot is not capable of looking next to you or checking your blind spot. Only nudge the wheel to initiate a lane change after you have confirmed it's safe to do so.
Many factors can impact the performance of openpilot ALC and openpilot LDW, causing them to be unable to function as intended. These include, but are not limited to:
The list above does not represent an exhaustive list of situations that may interfere with proper operation of openpilot components. It is the driver's responsibility to be in control of the vehicle at all times.
openpilot ACC and openpilot FCW are not systems that allow careless or inattentive driving. It is still necessary for the driver to pay close attention to the vehicle’s surroundings and to be ready to re-take control of the gas and the brake at all times.
Many factors can impact the performance of openpilot ACC and openpilot FCW, causing them to be unable to function as intended. These include, but are not limited to:
* Poor visibility (heavy rain, snow, fog, etc.) or weather conditions that may interfere with sensor operation.
* The road facing camera or radar are obstructed, covered, or damaged by mud, ice, snow, etc.
* Obstruction caused by applying excessive paint or adhesive products (such as wraps, stickers, rubber coating, etc.) onto the vehicle.
* The EON is mounted incorrectly.
* Approaching a toll booth, a bridge or a large metal plate.
* When driving on roads with pedestrians, cyclists, etc...
* In presence of traffic signs or stop lights, which are not detected by openpilot at this time.
* When the posted speed limit is below the user selected set speed. openpilot does not detect speed limits at this time.
* In presence of vehicles in the same lane that are not moving.
* When abrupt braking maneuvers are required. openpilot is designed to be limited in the amount of deceleration and acceleration that it can produce.
* When surrounding vehicles perform close cut-ins from neighbor lanes.
* Driving on hills, narrow, or winding roads.
* Extremely hot or cold temperatures.
* Bright light (due to oncoming headlights, direct sunlight, etc.).
* Interference from other equipment that generates radar waves.
The list above does not represent an exhaustive list of situations that may interfere with proper operation of openpilot components. It is the driver's responsibility to be in control of the vehicle at all times.
The list above does not represent an exhaustive list of situations that may interfere with proper operation of openpilot components. A driver should not rely on openpilot DM to assess their level of attention.
By default, openpilot uploads the driving data to our servers. You can also access your data by pairing with the comma connect app ([iOS](https://apps.apple.com/us/app/comma-connect/id1456551889), [Android](https://play.google.com/store/apps/details?id=ai.comma.connect&hl=en_US)). We use your data to train better models and improve openpilot for everyone.
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://my.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.

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.
You can add support for your car by following guides we have written for [Brand](https://medium.com/@comma_ai/how-to-write-a-car-port-for-openpilot-7ce0785eda84) and [Model](https://medium.com/@comma_ai/openpilot-port-guide-for-toyota-models-e5467f4b5fe6) 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.
