[H1] openpilot is an
open source
advanced driver assistance system that works on 325+ car models of Toyota,
Hyundai, Honda, and many other brands.
Automated Lane Centering Adaptive Cruise Control Lane Change Assist Driver Monitoring (no wheel nags) Can drive for hours without intervention Open source and developed on GitHub 01
[H2] Makes driving chill
Currently, openpilot performs the functions of Adaptive Cruise Control
(ACC) and Automated Lane Centering (ALC). openpilot can accelerate,
brake automatically for other vehicles, and steer to follow the
road/lane. When openpilot is enabled, a driver monitoring system watches the driver
and ensures the driver is attentive and ready to take over at all times. When used correctly, these features reduce your workload as a driver,
and can make long drives relaxing instead of tedious. 02
[H2] Connects to your car
openpilot works by connecting to your car's CAN network. 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. 03
[H2] Modern machine learning
openpilot contains a state-of-the-art neural network that understands
the road scene and predicts where to drive. This neural network has
learned to drive by watching the millions of miles of driving data
openpilot has recorded. This makes openpilot exceptionally good at
nuanced situations such as driving in areas with faded lanelines,
different countries, and more. 04
[H2] Open source and community supported
openpilot is developed by comma and by users like you. We welcome both
pull requests and issues on

Our 20,000+ users have driven over 300 million miles with a device
running openpilot. Over 56% of those miles were driven by openpilot,
with the driver supervising. What is openpilot?

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:

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.
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.
How does openpilot work?
openpilot works by connecting to your car's CAN network. Most modern cars
accept electronic steering, gas, and brake commands to allow for driver assistance
features. openpilot can use these commands to provide much better driver assistance
features than the car manufacturers can provide.
Is my car compatible with openpilot?
A complete list of compatible vehicles can be found on our
Compatibility page.
What should I buy to run openpilot in my car?
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!
Do I have to pay attention?
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.
What is the openpilot safety model?
More info about the openpilot safety model can be found
here.
What are the limitations of openpilot Automated Lane Centering?

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.
What are the limitations of openpilot Adaptive Cruise Control?

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.
Do I retain my car factory safety features with openpilot installed?

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.
Does openpilot support manual transmission cars (with the driver shifting)?
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.
How does openpilot recognize the car model it is connected to?

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.
How do I update openpilot?
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.
Will all versions of openpilot work with my comma device?

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.
Does openpilot work at all speeds?
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.
Does openpilot work outside of the United States of America?
Yes, openpilot is not region locked and can be used in any country. You are
responsible for complying with local laws and regulations.
What is a fingerprint?

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.
Where is my dongle ID?
The dongle ID of your device can be found in Settings of the device in the
Device tab.
How do I leave feedback for openpilot?
Feedback, good or bad, can be given in the #openpilot-experience channel on
our community Discord.
