Part 1. Human vs AV

1. Cognitive Differences

First, the process of mechanical and human drivers making decisions in the car is not so different. The control loop, called OODA (Observe-Orient-Decide-Act), shows a cyclical process of control machine which was first devised by the United States Air Force.

  1. Look around with multiple sensors.
  2. Localize themselves in the situation with a computer and cloud networking in the vehicle.
  3. Based on data from all sensors and the cloud, judge the next action.
  4. Operating the vehicle.

2. Communication failure

Another factor causing unstable autonomous driving is the failure of communication between humans and machines.

  • Information for human drivers
    With the development of autonomous driving technology, the human role is now closer to a supervisor, not a real driver. Human is on top of the loop with semi-AV. In other words, the information we need while driving has also changed. Inside the vehicle, indicators that evaluate the operating ability of a machine driver are more important, not information necessary for driving, such as speedometers and traffic information.

  • Communication methods for human drivers
    The medium of the interface is as important as the contents of the information to be delivered to human drivers. With the development of technology, communication with cars while driving has become possible not only with physical keys and buttons, but also with cell phones, hand gestures, and voices.
