Mercedes-Benz Intelligent Drive: E-Class Coupé with Active Braking Assist

An insufficient distance and distractions are the main causes of severe accidents. Active Braking Assist protects from accidents in many ways. And this is how it works:

  • Distance warning and audible collision warning.

If the distance to the vehicle ahead drops below the safe distance for several seconds within the speed range of the distance warning system, a warning icon lights up on the multifunction display. If the distance continues to reduce quickly, the system also emits audible warning bleeps.

  • Situation-specific brake boosting effect.

If drivers respond with an emergency braking manoeuvre, they can benefit from situation-specific brake boosting. If necessary, the feature builds up additional brake pressure to try and prevent a collision.

  • Autonomous braking.

If the driver does not respond, the system initiates autonomous braking. This reduces the speed significantly. At low relative speeds, this intervention is sufficient to prevent a rear-end collision. If drivers press the brake pedal during the autonomous braking manoeuvre, the situation-specific brake booster is activated and decelerates the vehicle to a complete stop if the situation requires.

  • Autonomous emergency braking manoeuvre for pedestrians.

The emergency braking function is intended to help prevent accidents with pedestrians whom the driver overlooks or who are not paying full attention when crossing the road and to mitigate the consequences of accidents. If the radar sensors identify a potentially dangerous situation, the emergency braking manoeuvre is activated at almost exactly the same time as the visual and audible warnings are issued.
