Mercedes-Benz Brake Assist System

November 13th, 2015 by




One of the most humorous commercials making the rounds on television right now involves giving children a set of Mercedes-Benz toy cars, and letting them try to crash them into each other, like we all did with our Matchbox and Hot Wheels cars when we were kids. Unlike our cars though, these have a little trick inside – powerful magnets that prevent the toy cars from crashing head-first into each other. Watching the kids get frustrated at not being able to crash their toy cars into each other is sure to bring a bit of a smile to your face. Underneath it all lies our aim of creating vehicles that make it nearly impossible to get into an accident with, starting with our Brake Assist System and our PRESAFE® system.

The Science Behind the System

The Mercedes-Benz Brake Assist System doesn’t quite work that way – after all, that would certainly cause some issues on the roadways. How our Brake Assist System (BAS®) actually functions is that it uses multiple sensors that scan the area ahead of the vehicle. These sensors include a long-range forward-facing system that projects up to 200 meters ahead, and the width of three traffic lanes. A mid-range radar system covers a shorter length at a higher beam angle, while two extremely wide-angle short-range sensors have a range of only 30 meters, but a full 80-degree range of vision. These staggered systems allows for better predictability regarding a collision or a miss. The system will then optimize the brakes to stop when the driver steps on the brake or, if no braking is detected, the system will initiate emergency braking. When emergency braking happens, the brake lights in the equipped vehicle flash rapidly to warn drivers in vehicles behind you to help prevent a rear-ending.

Thanks to recent advances, the BAS® doesn’t just detect other vehicles on the road either. It can detect pedestrians, even at speeds up to 45 miles per hour, and avoid hitting a pedestrian at a speed up to 30 miles per hour. Cross-Traffic Assist helps to detect potential collisions with cross traffic, such as at four-way intersections, thanks to additional stereo camera and radar sensors.

Mercedes-Benz PRESAFE® System

The Brake Assist System is just one of the many tools that is part of the Mercedes-Benz suite of safety systems. Of course, preventative measures can only go so far, so Mercedes-Benz has the PRESAFE® system for its vehicles. This exclusive system can sense an imminent collision and automatically prepares the vehicle for an incident. This includes:

  • Tightening the front seat belts
  • Adjusting the front head rest and front passenger seat
  • Closing the windows and sunroof

These help the restraint system, including the multiple available airbags, to deploy safely and effectively, increasing the chance for driver and passengers to survive the accident. When this is combined with the Brake Assist System, both the passengers in your vehicle plus others on the road can know they are safe and secure around your Mercedes-Benz.

While Mercedes-Benz is a little humorous when it comes to commercials, they are incredibly serious when it comes to keeping you and your family safe in your vehicle. Every vehicle sold here at Mercedes-Benz of Massapequa comes with some of the best active and passive safety systems on the market, not to mention many optional safety systems to increase your confidence and sense of safety behind the wheel. Whether you are in Babylon, Islip, or elsewhere on Long Island, it is worth the drive to our showroom in Amityville to see the Brakes Assist System, PRESAFE® system, and all of the other Mercedes systems in person, and learn more from our dedicated staff.
