Overview

openpilot is an open-source advanced driver assistance system (ADAS) designed to enhance driving by automating key functions like lane centering and adaptive cruise control. It works with over 325 supported car models, including brands like Toyota, Hyundai, and Honda, by connecting directly to the vehicle’s CAN network.

The system can steer, accelerate, and brake automatically while following the road, helping reduce driver workload on long trips. A built-in driver monitoring system ensures the driver remains attentive and ready to take control at all times.

Powered by modern machine learning, openpilot uses a neural network trained on millions of miles of driving data to handle real-world scenarios, including faded lane markings and diverse road conditions. It is community-driven, with active contributions on GitHub and continuous updates.
