01

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

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

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

Open source and community supported

openpilot is developed by comma and by users like you. We welcome both pull requests and issues on GitHub. Bug fixes and new car ports are strongly encouraged. Check out the contributing docs.
