Fatigue detection
The fatigue detection system (hereinafter referred to as the system) recom-
mends the driver takes a break from driving when driver fatigue can be detec-
ted due to the driver's steering behaviour.
From the starting of the journey, the system evaluates the steering behaviour
at speeds 65-200 km/h. If, while driving, there have been changes in the steer-
ing behaviours that are evaluated by the system as indicating possible fatigue,
a break recommendation is issued.
Conditions under which a break from driving is detected by the system
▶
The vehicle is stopped and the ignition switched off.
▶
The vehicle is stopped, the seat belt removed and the driver's door opened.
▶
The vehicle is stopped for more than 15 minutes.
