How Does Mercedes-Benz Attention Assist Work?

When you own a Mercedes-Benz, long trips don’t seem quite as daunting. With superior comfort and ride quality, exceptional sound, and plenty of horsepower to keep things exciting, a Mercedes-Benz will change the way you look at lengthy business travel or weekend trips back home to visit the folks. No matter how great the driving experience, long trips are prone to drowsiness. To help drivers recognize inattentive driving due to fatigue, Mercedes-Benz developed Attention Assist, one of many active safety features available in new models.

What is Mercedes-Benz Attention Assist?

Mercedes-Benz Attention Assist is an industry-first technology designed to alert drivers when they begin showing signs of fatigue behind the wheel. The system not only makes the driver aware of behavior that may be influenced by drowsiness, but also helps drivers correct their errors.

Driver Fatigue Mercedes-Benz Attention Assist SleepyDriver fatigue may sound like an incredibly difficult factor to monitor, but much like Lane Keeping Assist and Blind Spot Assist have helped drivers be more aware of there surroundings, Mercedes-Benz Attention Assist helps drivers be more aware of themselves.

So how does Mercedes-Benz Attention Assist work? Well, it all starts within a few minutes of entering the vehicle. Soon after drivers begin on their journey, the system creates an individual profile of the driver, recognizing behavior while the driver is fully alert. That profile is used as the basis for comparison during the rest of the drive.

Mercedes-Benz Attention Assist uses a highly sensitive sensor that monitors and records steering movement and speed. Research done by Mercedes-Benz showed that when drivers are fatigued, they will change their steering behaviors and make more errors, which are normally corrected quickly. When Attention Assist recognizes the vehicle drifting and being quickly readjusted back onto the center of the road or notices a change in driving behavior, it will go on to check several other parameters to see if the change is due to fatigue or other factors.

Attention Assist will examine considerations such as time behind the wheel, driver activity, weather, and road surface influences, and a variety of other factors that may be causing the irregular driving behavior. If the system determines drowsiness is the cause, it will send an audible and visible alert letting the driver know it’s time to take a break.

While Mercedes-Benz offers a number of technologies to help drivers be more aware of their surroundings, Attention Assist is the industry’s only technology that helps drivers monitor their own behavior.

    Is it possible to post-install attention assistance system into coaches? We have one year old MB Tourismo coaches, without AA, but it would be necessary to install it into the coaches. Allegedly, Mercedes Benz doesn’t do it additional, but it’s hard to believe. How can it be solved?

    Thank you!
