The company behind openpilot

An open source progressive web app used to view drives and interact with the device remotely

link to docs

A universal interface to your car. A unique harness exists for each of the supported makes and models of cars. This replaces the older giraffe Connector

A device that provides stop-and-go capability on cars that don't currently support it. This device is not sold by comma.ai (not officially supported by them), but supported in openpilot.

Awarded for various activities you perform on the platform. Good for bragging rights.

Use your car's OBD-II port to power your Toyota, Bosch, or FCA giraffe. CPv1 was the initial version, for use w/ giraffes. CPv2 came out later, used with comma harness, and has an RJ45 jack.

A subscription service from comma.ai offering a specific list of benefits

The latest generation devkit from comma. Runs Ubuntu linux and suppors the latest openpilot releases. Has an integrated panda (dos). Supports using an external red panda to interface with CAN-FD vehicles.

A smartphone running a customized version of Android and a custom case with additional cooling. This device runs the openpilot software and has an integrated panda (uno)

The previous generation of the comma two devkit. It did not have an integrated panda

A list of CAN bus signals unique to a particular vehicle. Allows openpilot to recognize which car it is connected to. CAN-based FPv1 is now deprecated; emphasis is now on firmware-based FPv2.

"Free EON"... an open source variant of the EON case. The repository contains files that can be used for 3D printing a case. Developed by @Chase#7213

An adapter board that lets you read buses that aren't exposed on the main OBD-II connector, with variants for different vehicle makes/models.

Activate the turn signal and gently nudge the wheel in the direction you wish to travel to when it's safe. Change lanes while always paying attention.

The phone used in comma two and EON Gold devkits

A continually updated file (ie. "Live") that stores learned calibration data for the vehicle.

One of the phones used in the previous generation EON devkits. It was discontinued due to a lack of supply. Known model numbers: A3000(US version) A3010(Asian version)

An open source driver assistance system developed by comma.ai

CAN bus interface. Available in 3 variants: white (last supported 0.7.6.1) / grey (last supported 0.7.10) / black. Internal pandas are also found inside the

A device to help you unbrick a panda.

Model == neural network. Full frame is 1164x874, little model is a 512x256 crop, big model is a 1024x512 crop, 4x bigger than little. Make box bigger, drive better. Useful for signs and lights.

End to end means the model reacts like a human would. It assesses the whole picture and acts accordingly. Unlike other approaches where things must be labeled by hand, end to end learns all the nuances of driving. A model is basically trained on what human drivers would do in a certain situation and attempts to reproduce that behavior.

Refers to gas and brake control

Refers to steering control

An advanced method of process control that is used to control a process while satisfying a set of constraints. Used for longitudinal and lateral control.

Selected radar point from your car's radar by the driving model of openpilot using the camera. Used for longitudinal MPC. Usual attributes: distance, speed, and acceleration

A cruise control system that automatically adjusts the vehicle speed to maintain a safe distance from vehicles ahead.

Electronic systems that aid the driver.

A system designed to keep a car centered in the lane, relieving the driver of the task of steering.

A system designed to prevent or reduce the severity of a collision.

A system that uses infrared sensors and/or cameras to monitor driver attentiveness

A cruise control system that automatically adjusts the vehicle speed to maintain a safe distance from vehicles ahead.

An undesired behavior where the vehicle drives too closely to one side of the lane.

Lane keep assist is what comes with most cars sold today. It will assist the driver if they go over a lane line, but will not keep the car centered in the lane.

Lane departure warning will beep when a car goes over a lane line.

A system that uses computer and artificial intelligence technology to recognize pedestrians and bicycles in an automobile's path to take action for safety.

An undesired behavior where the vehicle sways from one side of the lane to the other repeatedly. The desired behavior is to stay in the center of the lane.

Similar to ping pong, but where the vehicle drives mostly centered in the lane but sways slightly from side to side. Primarily due to improper tuning of the steering control system, influence from wind, or poor lane/path perception due to rain, dirt, and/or debris on the vehicles windshield.

A system by which a vehicle is able to recognize the traffic signs put on the road e.g. "speed limit" or "children" or "turn ahead".

The ability for the car to be brought to a standstill and then resume driving without needing to disengage or reengage openpilot.

The exclusive use of cameras instead of radar to provide adaptive cruise control functions.

A message-based protocol that provides a standardized way for ECUs to communicate with each other.

A newer version of CAN that supports higher data rates and longer messages. A red panda is required to interface with CAN-FD vehicles for Comma 2 and Comma 3. Not required for Comma 3x, as the Panda is built in.

Any embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a vehicle.

Uses an electric motor to assist the driver of a vehicle. Sensors detect the position and torque of the steering column, and a computer module applies assistive torque via the motor, which connects to either the steering gear or steering column.

OBD systems give the vehicle owner or repair technician access to the status of the various vehicle sub-systems. The comma power v2 uses this port to provide constant power to the comma two as well as access the diagnostic bus for FW query.
