In particular on long trips and when driving at night ATTENTION ASSIST can increase driving safety. Based on the driver's steering behaviour the system recognises typical signs of fatigue and severe inattentiveness and issues visual and audible warnings of impending microsleep.
A five-level bar graph in the instrument cluster multifunction display represents the current attention level of the driver. The time elapsed since the last break is also shown.
If the driver's attention level declines too far, a coffee cup icon is displayed to inform that a break is advisable; an audible warning sounds as well. At the same time COMAND Online offers to search for a Services Area. If the setting "Sensitive" is selected, the system warns the driver even earlier.
ATTENTION ASSIST works at speeds between 60 and 200 km/h: it can be set to display a warning in the instrument cluster at a determined (in)attention level and can be switched off entirely.
