How Does the ATTENTION ASSIST® Feature Work in Mercedes-Benz?

Maintaining focus can be challenging when going on long journeys or navigating monotonous stretches of highway. Fortunately, Mercedes-Benz has equipped its vehicles with cutting-edge safety technologies to make driving safer and more comfortable.  

One such innovation is the ATTENTION ASSIST® feature. Available in many Mercedes-Benz models, this intelligent system acts as a co-pilot, monitoring the driver’s behavior and providing timely warnings to prevent fatigue-related accidents. This page by our experts at Mercedes-Benz of Arrowhead in Peoria, AZ, will help you better understand the ATTENTION ASSIST® feature.

Understanding ATTENTION ASSIST®

The ATTENTION ASSIST® system is specifically designed to assist drivers during extended trips or under conditions that can lead to drowsiness. By continuously analyzing various factors, including steering behavior and other inputs, the system identifies signs of fatigue or lapses in concentration. If it detects these indicators, ATTENTION ASSIST® suggests taking a break to ensure driver safety and attentiveness.

However, it’s important to note that ATTENTION ASSIST® is an aid, not a replacement for an alert and well-rested driver. Regular and timely breaks remain essential, especially on long road trips.

How ATTENTION ASSIST® Works

The ATTENTION ASSIST® feature analyzes the driver’s actions and patterns during the journey. Here’s how the system functions:

Monitoring Behavior

When you start driving, ATTENTION ASSIST® begins monitoring factors such as steering patterns, driving speed, and other subtle movements. It compares these data points to the typical characteristics of an attentive driver.

Detecting Fatigue

If the system identifies deviations indicating fatigue or lapses in concentration, a warning message appears on the driver’s display: “ATTENTION ASSIST: Take a Break!” A sound alert often accompanies this warning to ensure the driver’s attention.

Microsleep Detection

With the help of a driver camera, ATTENTION ASSIST® can detect signs of microsleep—brief moments of unintended dozing off. When this occurs, the system displays an urgent “Nodding Off Take a Break!” warning, prompting immediate action.

Break Suggestions

If a break is needed, the multimedia system can assist by suggesting nearby rest areas and navigating to them. This thoughtful integration helps drivers find suitable resting places before resuming their journey.

Attention Level Feedback

The system also provides real-time feedback on the driver’s attention level through a visual indicator on the display. A circular graphic shows the detected attention level, with fewer segments displayed as concentration decreases.

Customizing ATTENTION ASSIST® Sensitivity 

Mercedes-Benz understands that every driver is different, which is why the ATTENTION ASSIST® system offers two sensitivity settings: 

  • Standard Mode: Normal system sensitivity, ideal for most driving conditions. 
  • Sensitive Mode: Higher sensitivity, providing earlier warnings to drivers who may require additional alerts. 

These customizable options ensure the system adapts to your needs, enhancing its effectiveness.

Key Considerations and Limitations 

While ATTENTION ASSIST® is a remarkable technological innovation, it’s essential to understand its limitations. 

  • The system operates effectively from 37 mph to 124 mph for general fatigue detection and 12 mph or higher for microsleep detection. 
  • External factors, such as poor road conditions, strong winds, or incorrect clock settings, may impact the system’s performance.
  • Certain conditions, such as obscured vision due to eyeglasses, low light, or steering column positioning, can limit microsleep detection capabilities.
