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 EON 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.
