The American Automobile Association has tested autonomous driver attention monitoring systems to determine their effectiveness. Modern cars are equipped with two types of such systems. In the first case, a set of sensors monitors the frequency of rotation of the steering wheel. The second technology allows you to track the movement of the driver’s eyes. Subaru Forester, Cadillac Escalade, as well as Tesla Model 3 and Hyundai Santa Fe took part in the tests. According to the results of the research, the experts concluded that both existing technologies are not effective enough.
All four vehicles are equipped with a level 2 autonomous system that requires drivers to keep their hands on the wheel and keep their eyes on the road. During the tests, experts found that the complex, following the direction of sight, takes about ten seconds to respond to an emergency situation. For example, if the driver released the steering wheel or closed his eyes. At a speed of one hundred kilometers per hour, a car travels about one and a half kilometers in ten seconds. During this time, anything can happen on the road. In addition, the camera-based complex may fail if the driver uses sunglasses.
The situation is even worse with the control system using sensors on the steering wheel. Such a complex notifies that the driver removed his hands from the steering wheel in a minute. During this time, when driving at a speed of one hundred kilometers per hour, the car will travel approximately ten kilometers. According to the results of the research, the experts concluded that it is necessary to increase the reaction rate of such systems. However, it is still not clear how quickly such complexes should notify the driver.
