AA – Attention Assist
It doesn't distract. Unfortunately, drowsiness is one of the most common causes of accidents and deaths on the roads, and this Mercedes-Benz Attention Assist is a step forward in the fight against attention loss due to fatigue. Considering that this level of self-awareness is required to realize this, let's take a look at how it works together.
The complex device takes into account multiple indicators of the driver's attention level to decide when to intervene. By observing the driver's behavior during each trip, the on-board computer generates and saves a profile, which is then reused as a basis for interpreting what the driver is doing while driving moment by moment.
When the system detects a significant deviation from normal behavior, it compares it with certain parameters, such as already known signs of fatigue, distance traveled since the start of the trip, time of day and driving style.
If deemed appropriate, the device intervenes to alert the driver. The warning consists of audible and visual signals that invite you to leave the guide and rest.
The level of complexity of the data stored in the on-board electronics is incredible: all parameters are not overlooked. Longitudinal and lateral acceleration, steering angle, use of direction indicators and gas and brake pedals, and even road conditions, wind speed and direction intersect to give a reliable picture of the driver's level of attention to plan an intervention. it is as efficient as possible.
Steering angle seems to be one of the most diagnostic parameters of fatigue, since as sleep approaches, the driver makes a range of typical movements and corrections that appear to be unmistakable.
