Support & FAQs

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 connecting to your car's CAN network. Most modern cars accept electronic steering, gas, and brake commands to allow for ADAS features. openpilot can use these commands to provide much better ADAS features than the car manufacturers can provide.

A complete list of compatible vehicles can be found on our Compatibility page.

After verifying that your car is compatible, we recommend purchasing a comma device in our shop. Don't forget to purchase a car harness to connect it to your vehicle. Add to cart, check out, and you’re good to go!

Yes, the driver must always be able to immediately retake manual control of the vehicle, by stepping on the brake 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.

More info about the openpilot safety model can be found here.

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.

When openpilot is enabled in settings, Lane Keep Assist (LKAS), and Automated Lane Centering (ALC) are replaced by openpilot lateral control and only function when openpilot is engaged. Lane Departure Warning (LDW) works whether engaged or disengaged.

On certain cars, Adaptive Cruise Control (ACC) is replaced by openpilot longitudinal control.

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

On certain cars, manual transmissions are supported if they have the packages listed in the compatibility table. If you’d like to learn more, join us on Discord, where some of our members are supporting manual cars.

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). openpilot will automatically check for updates when connected to the internet. Your device will notify you on the screen when an update is available and prompt you to reboot the device to complete the update.You may also manually check for updates in the settings, under the "software" tab.

The comma 3X can only run openpilot 0.9.4 and above. Running earlier versions requires making modifications to the software so that a newer AGNOS is installed.

If you face issues after installing an older version of openpilot, you can re-flash AGNOS on your device by following the instructions at flash.comma.ai.

Supported speeds vary depending on the car. Please reference the supported car list for vehicle specific speed limitations. Maximum speed is the same as the maximum speed that stock ACC can be set to (car dependent) with a hard limit at ~92mph.

A fingerprint is the method openpilot uses to determine which vehicle it is connected to.

Current methods use vehicle ECU firmware logging. openpilot will fingerprint the vehicle on each start up.

If openpilot detects a firmware version not previously logged, it will need to be added to the codebase. Guides on adding new firmware can be found here.

The dongle ID of your device can be found in Settings of the device in the Device tab.

Feedback, good or bad, can be given in the #openpilot-experience channel on our community Discord.

The free prime offer must be claimed within 30 days of purchase and a credit card must be provided.

Live outside the United States? You can still sign up for prime lite by bringing your own active SIM card.

connect (connect.comma.ai) is a dashboard of your recent drives.

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

connect provides other features such as battery voltage, snapshot, and navigation guidance.

With prime ($24/mo), domestic data is included (comma 3/3X only).

With prime lite ($16/mo), you must also provide your own SIM card with an active data connection.

We aren't able to transfer comma prime subscriptions between devices. To do so, you must cancel your existing prime subscription through connect.comma.ai and sign up with the new device.

We've made the Refund Policy as straightforward as we can, no hidden clauses and no fine print.

• You may cancel your subscription by selecting the "Cancel subscription" option on connect.comma.ai in the settings cog -> "Prime Settings". You can do this at any time without incurring a cancellation fee. Upon canceling your comma prime membership, no further fees will be charged.
• If you have a free trial period, we will charge your credit card with the monthly subscription fee at the end of the trial period.
• We will continue to charge your credit card account on a monthly basis until you cancel your subscription. For example, if you joined on April 5 your credit card will be charged on May 5; June 5; July 5; and so on until you cancel your subscription.
• Your cancellation takes effect immediately.

Installing a comma device does not require any permanent modifications to your car. With the car harness, most car trims remain in place.

We recommend the mount be centered on the windshield below the trim (see pictures in the Installation Guide). Be sure to leave enough room to remove the trim in the future. First, clean the windshield with the included alcohol wipe. Ensure the top of the mount is fully visible from the driver’s seat. Adhere mount: peel off the 3M tape’s cover on the mount. Press firmly in the center of the mount, then the edges to ensure no bubbles form.

Let the mount cure: the mount must cure for 48 hours before installing the comma device. Skipping this step will compromise the integrity of the mount.

The 3X mount may be difficult to slide onto the device before it’s installed on the windshield. This is expected and will be easier to do once the mount is installed and fully cured. Some force may be necessary to initially slide the device on the mount. Before applying any force, ensure the device mount is parallel to the mount on the windshield so it will slide in correctly.

IT IS THE USER’S RESPONSIBILITY TO MOUNT THE DEVICE IN COMPLIANCE WITH ALL APPLICABLE LAWS AND ORDINANCES.

From the FTC website: "Simply using an aftermarket or recycled part does not void your warranty. The Magnuson-Moss Warranty Act makes it illegal for companies to void your warranty or deny coverage under the warranty simply because you used an aftermarket or recycled part."

Contact your insurance provider directly; insurance coverage is between the user and their insurance provider. comma hardware users have been able to get coverage and discuss this on reddit here.

Insurance companies are beginning to understand the safety benefits of ADAS and LKAS systems like openpilot and we have not heard of any providers rejecting coverage to comma hardware users.

Although there's no official support for any software, it is comma's policy to continue providing software updates to hardware for 1 year after it is the latest generation sold.

comma body is “the future of people.” You buy a comma body, buy a comma 3X (the head), attach the comma 3X to the body, and watch it come to life.

We believe that in order to solve AI, for most people’s definition, you must be embedded in the real world. We define AI as a machine that can do every task at least as well as a human. And in order to do human tasks, it helps a lot to have a human like body. The comma body is the beginning of that journey.

Today it’s a mobile platform for the comma 3X, but we will be building a knee and arms for it. Like everything we do, we try to distill the problem down to its essence, so unlike some companies, we aren’t focused on the humanoid shape. Wheels are a fine form of locomotion for cooking and cleaning, the dream tasks of the comma body. Two arms, a knee, and a comma 3X should complete a comma person (sold separately, knee and arm coming in 2023).

The comma body runs openpilot! From openpilot's perspective, the comma body is a car. It runs the same camera and logging software, so we'll be able to learn from the fleet of bodies in the same way we learn from our fleet of cars.

At launch, the software will balance the body (using the same localizer as the car!) and allow you to drive it around via web interface. Shortly we’ll add video streaming to that web interface, allowing you to drive your body outside line of sight. We’d also like to add a VR app to drive the body from a first person view, this will be needed by the time we ship the arms.

Once we start getting data back from our body fleet, we can train models. The first model we will train (jointly with the driving model!) is a posenet, allowing inside out position tracking. When this model is shipped, the localizer will change from 3-DoF to 6-DoF. And once the dead reckoning is similar quality to what we have on the cars, adding a SLAM system will be very simple to allow drift free localization in your environment.

Every vehicle is a little different and the experience can be hard to describe which is why we offer this trial. If you don’t love the comma 3X, you can return it for a full refund–no questions asked.

Our comma shop return policy applies: you have 30 calendar days to return the 3X from the date you received it. We offer return labels for $9.99 which will be deducted from your return (US only). All refunds must be initiated through comma.ai/returns

All comma 3Xs (shipped in the US) come with a SIM card. The SIM slot is a push/pull mechanism, where you must push on the card to release it and then guide it out.

Make sure your SIM is inserted correctly by following the step-by-step guide below:

How to replace the SIM card in a comma 3X

1. With the comma 3X off and unplugged, tap/push the SIM card with the big SIM card, credit card, or other narrow hard object to release the SIM (you will hear a click).

2. Gently pull the SIM card from the SIM slot (try tweezers)

3. Push the SIM card into the SIM slot (with the metal contacts facing downwards) with your fingernail or plastic card until you hear a click or reach resistance. If you've done this step correctly, the SIM card should stay completely recessed inside the comma 3X.

We recommend you clean the camera lenses with a microfiber cloth before using the comma 3X again.

How to activate the new SIM card

Once your new SIM card is installed, your comma 3X will need to connect to Wi-Fi to activate the SIM card. Best ways to get your comma 3X online: hotspot from your phone, bring your car somewhere with Wi-Fi or connect your comma 3X to a USB charger in a place with Wi-Fi. Your comma 3X requires about 5 minutes of Wi-Fi connection and then can take up to 30 minutes to activate and might require a reboot. You will know the activation started when the device displays "CONNECT ONLINE".

After the next reboot, your SIM card should connect to the internet and you should have prime again!

comma 3X has supercapacitors. When unplugged, allow them to fully drain for 30 seconds before plugging the device back in.
