comma openpilot is an open source driver-assistance system. Currently, openpilot performs the functions of Adaptive Cruise Control (ACC) and Automated Lane Centering (ALC) for compatible vehicles. It performs similarly to Tesla Autopilot and GM Super Cruise. openpilot can steer, accelerate, and brake automatically for other vehicles within its lane. Check it out on GitHub.

In order to enforce driver alertness, openpilot includes a camera based Driver Monitoring (DM) system that alerts the driver when distracted or asleep. However, even with an attentive driver, we must make further efforts for the system to be safe. We have designed openpilot with two other safety considerations:

1. The driver must always be capable to immediately retake manual control of the vehicle, by stepping on either pedal or by pressing the cancel button.
2. The vehicle must not alter its trajectory too quickly for the driver to safely react. This means that while the system is engaged, the actuators are constrained to operate within reasonable limits.

openpilot works by taking the radar data integrated with supported car models and combining it with the camera built into comma hardware, to determine what acceleration, braking, and steering events are required.

An accurate list of compatible vehicles can be found here: https://github.com/commaai/openpilot.

After verifying that your car is compatible, we recommend purchasing a comma two in our shop. Don't forget to purchase a car harness to connect it to your vehicle. All Toyota harnesses are the same. Add to cart, check out, and you’re good to go! We offer free shipping in the US and flat rate international shipping for $30.

Yes, the driver must always be able to immediately retake manual control of the vehicle, by stepping on either pedal or by pressing the cancel button. When openpilot is engaged, a driver monitoring system actively tracks driver awareness to help prevent distractions. The openpilot system disengages if you are distracted. Drivers must keep their eyes on the road at all times and be ready to take control of the car.

openpilot Automated Lane Centering (ALC) system does not automatically drive the vehicle or reduce the amount of attention that must be paid to the area in front of the vehicle. The driver must always keep control of the steering wheel and be ready to correct the ALC system action at all times.

Many factors can impact the performance of openpilot ALC, causing it to be unable to function as intended. These include, but are not limited to:

• Poor visibility (heavy rain, snow, fog, etc.) or weather conditions are interfering with sensor operation.
• The road facing camera is 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 device is mounted incorrectly.
• When in sharp curves, like on-off ramps, intersections etc...; openpilot is designed to be limited in the amount of steering torque it can produce.
• In the presence of restricted lanes or construction zones. 
• When driving on highly banked roads or in presence of strong cross-wind.
• Extremely hot or cold temperatures.
• Bright light (due to oncoming headlights, direct sunlight, etc.)
• Driving on hills, narrow, or winding roads.

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 Adaptive Cruise Control (ACC) is not a system that allows 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, causing it to be unable to function as intended. These include, but are not limited to:

• Poor visibility (heavy rain, snow, fog, etc.) or weather conditions are interfering 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 device is mounted incorrectly.
• Approaching a toll booth. 
• 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 ultrasonic 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.

Lane Departure Warning (LDW), Lane Keep Assist (LKAS), and Automated Lane Centering (ALC) are replaced by openpilot lateral control and they only function when openpilot is engaged.

Adaptive Cruise Control (ACC) is replaced by openpilot longitudinal control.

openpilot preserves any other vehicle's stock features, including, but are not limited to: AEB, auto high-beam, blind spot warning, and side collision warning.

If your car is on the list of supported cars, openpilot will automatically recognize the model of your car by performing a scan of relevant ECU firmware versions present in your car. The presence of certain ECU firmware versions is an indication of the model year, car brand, car model, and trim.

If your car isn’t recognized as supported, your device will fall back to a dashcam only mode, preserving the stock functionalities and the user will receive a notification on the screen.

All software updates are received over-the-air (OTA). Your device will notify you on the screen when an update is available and prompt you to reboot the device to complete the update.

Supported speeds vary depending on the car. Please reference the supported car chart for vehicle specific speed limitations. Maximum speed is the same as the maximum speed that stock ACC can be set to (car dependent).

Check out your recent drives in Explorer. In Explorer, you can annotate disengagements (tell us why you took control of the vehicle) which helps improve the system and further development. 

Your drives are stored for 3 days (or 1 year with a comma prime subscription). 

Explorer (https://my.comma.ai/) is a dashboard of your recent drives. In Explorer, you can annotate disengagements (tell comma why you took control of the vehicle) which helps improve the system and further development.

comma is an MVNO, meaning we sell mobile service to all of you in the United States. Although you are buying service through comma, it should have coverage everywhere a certain major cell network does. It’s unlimited, meaning you can’t run out, though it is capped to 512 kbps of bandwidth.

All comma two ship with a comma prime SIM card and include 3 free months of comma prime (initiated on ship date). Download our app, comma connect, to claim your free comma prime; available on iOS and Android. 

With our new qlog infrastructure, you should be able to upload your routes in real time. And in the app, we’ll be rolling out more and more features that benefit from having an always connected device. We also have an SSH proxy that is available with comma prime. This, combined with the cell phone service, allows you to access your device remotely from anywhere. You’ll also have remote access to all the other methods in athena using our API.

With device version 0.6.1 or newer, enter your GitHub username on your device under Developer Settings. Your GitHub authorized public keys will become your authorized SSH keys for ssh.comma.ai. See ssh.comma.ai for further instructions.

comma does not have and does not want remote access to your device (unlike certain electric car companies), because your device is yours. You alone control your private key for remote access. Our security model is the same as SSH, so a compromise would likely mean someone has gained access to your private key (or an OpenSSH 0-day just compromised 80% of the internet!). comma does not have your private key and a comma employee will never ask you for your private key.

All EONs shipped after 7/17/2019 include a comma prime SIM card. The $24/mo service can be enabled in the comma connect app. Available on iOS and Android.
