Mercedes-Benz Celebrates 10 years of Pre-Safe Technology

October 15th, 2015 by


For the past few years, many car makers have been putting the idea of safety that looks ahead and helps to act to avoid an accident forward. In the last two to three years, this has become one of the most sought-after safety systems in the industry. While some companies are touting this as new technology, Mercedes-Benz has had versions of this technology for over a decade now, as standard equipment on numerous models.

What is Pre-Safe Technology?

Pre-Safe is active safety technology that detects probable collisions and helps drivers react appropriately or, if they do not respond, will act to try to avoid an accident. It is a system that was developed to make accidents more avoidable, and more survivable. Initially developed and put into Mercedes vehicles in 2002, it paved the way for many of the forward collision detection and mitigation systems that are in use today.

Pre-Safe uses sensors to detect conditions that can lead to accidents. In addition to detecting rapidly closing distance between the Mercedes and other cars or objects, it can detect a loss of traction or grip. It can also calculate lateral acceleration, steering angle, and car yaw, and can evaluate if loss of control is imminent. It will even provide limited steering feedback, small corrections that may help to bring the car back under control. Other triggers that can activate the Pre-Safe system includes panic braking, critical steering maneuvers, or detection inputs from the automatic cruise control system.

Pre-Safe has evolved over the years as well, adding more capabilities as Mercedes engineers figure out more parts of the puzzle. For instance, in the recent 2014 model year, pedestrian detection that can initiate autonomous baking was added to the system. This follows such evolutions as the ability to detect driver fatigue level, which was added in 2009, and the 2005 redesign that saw Brake Assist Plus become a bigger part. Best of all, Pre-Safe Technology is open-ended, so it is easy for Mercedes engineers to add on even more in the years to come.

How Does Pre-Safe React in an Accident?

Once Pre-Safe detects potential issues, it responds first by warning the driver using visual and audio warnings. If the driver does not react, the system automatically tightens the seat belts for extra safety, moves power seats automatically into the upright position, and primes the brakes for faster response. As stated before, it will even apply the brakes to an extent, but not to bring the car to a complete stop. This at least reduces the severity of the impending impact. Airbags are also primed for fast deployment at the moment of impact.

If the driver loses control, and the possibility of skidding or rollover is detected, Pre-Safe can also act in other ways to make the possible incident more survivable. Pre-Safe will automatically close the sunroof and all open windows, to prevent debris from flying in or body parts from flying out and becoming more vulnerable.

Mercedes-Benz now includes the Pre-Safe Technology on over 40 models of vehicles, vehicles that are available at Mercedes-Benz of Massapequa. From the C-Class to the S-Class, and on to the crossover and SUV ranges, Pre-Safe helps to makes Mercedes vehicles some of the safest on the road.
