Frequently Asked Questions

FAQ

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:

  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.
How does openpilot work?

openpilot works by taking the radar data integrated with supported car models and combining it with the camera built into comma hardware, to determine what acceleration, braking, and steering events are required.

Is my car compatible with openpilot?

A regularly updated list of compatible vehicles can be found here: https://comma.ai/vehicles.

What should I buy to run openpilot in my car?

After verifying that your car is compatible, we recommend purchasing a comma two in our shop. Don't forget to purchase a car harness to connect it to your vehicle. All Toyota harnesses are the same. Add to cart, check out, and you’re good to go! We offer free shipping in the US and flat rate international shipping for $30.

Do I have to pay attention?

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