The A7 concept is able to drive itself at speeds below 70 mph thanks to the combination of radar sensors and laser cameras. The A7 concept can make lane changes and passing maneuvers on its own—but before initiating a lane change, the vehicle adapts its speed to surrounding vehicles. If the speed and distance calculation is deemed safe, the vehicle initiates the lane change with precision and in a timely manner. The A7 concept is only capable of driving autonomously on the highway, so once a city environment is detected the system requests that the driver take over with multiple warning signals.
Audi hasn’t announced when it will release an autonomous vehicle, but does state that the technologies are production ready for vehicle production in the near future.
The Audi also drove itself around a race track and in First Person view.
