Because of the fact that one in five road accidents occur due to driver fatigue, driver fatigue monitoring system is an important safety feature. Driver fatigue monitoring system installed on the X-Trail, significantly increases the level of safety. Initially studying the driving style, the system analyzes and monitors the control action of the driver. If the system detects that the driver is tired, on the instrument panel the appropriate indicator will illuminate, reminding the driver to rest.
The pioneer in this difficult matter was the Volvo, production cars which have received Driver Alert Control workable system some of the first. The central role in it, as in many modern technologies, is given to electronics, which with the help of video cameras track the movement of the car with respect to road markings. Once the system determines that the frequency of precision steering and waggings exceeds the permitted limit, the driver will be “waken up” by the audio signal, and except this icon will light in the form of a coffee cup at the instrument panel.
