50 years of Mercedes-Benz Accident Research: Reality as the yardstick

Comunicato Stampa disponibile solo in lingua originale. 

For 50 years now, #MercedesBenz experts have examined serious accidents involving current vehicles bearing the three-pointed star. The insights of #MercedesBenz Accident Research are incorporated into the improvement and design of updated and new models. 

Just this September, #MercedesBenz celebrated an anniversary in the field of safety: 60 years of crash testing. The first crash test in the history of the brand took place on 10 September 1959. A test car slammed head-on into a solid obstacle. A new era in safety research: because ever since then it has been possible to study the crash behaviour of vehicles and occupants in more detail based on the test cars and test dummies. Crash tests are modelled on reality. #MercedesBenz Accident Research, which also celebrates a notable anniversary this year, deals directly with real-life accidents.

Established in 1969, #MercedesBenz Accident Research is one of the oldest departments of this kind in the global #automotive industry. Since then, the teams have examined and reconstructed more than 4700 traffic accidents. "The comprehensive approach of #MercedesBenz safety development pursues two objectives, preventing accidents and mitigating the consequences of them", emphasises Professor Rodolfo Schöneburg, #MercedesBenz Centre Manager for Vehicle Safety, Operational Stability and Corrosion Protection. "Our safety philosophy is 'real-life safety'. In addition to simulations and crash tests, what actually happens in accidents is an important aspect for us. Our accident research provides crucial insights from real accidents". 

Systematic reconstruction of collisions

Mercedes-Benz Accident Research has been systematically studying accidents for 50 years. Thanks to the cooperation with the Interior Ministry of Baden-Württemberg, the police report serious accidents involving a current #MercedesBenz or smart model that occur within a radius of about 200 kilometres of Sindelfingen. The work of the researchers usually starts on the accident vehicle in the workshop to which it was taken. In the next stage, the accident scene is visited to reconstruct the course of the accident even if only one vehicle was involved. Once they possess all the information, they systematically reconstruct the collision. Finally, the results are compared with the data from other accidents, so that over time, the #automotive engineers get a precise picture of typical damage patterns and gain insights for the development of new, even more effective protection systems. In order not to jeopardise their impartiality as researchers, the accident research experts never prepare any expert opinions for parties involved in an accident or as expert witnesses for the judicial system.

All road users benefit from their painstaking detective work and their insights gained: numerous #MercedesBenz safety innovations such as ESP®, the window airbag or PRE-SAFE® have been developed on the basis of the accident research findings from real-life accidents. The results are also used as a basis for developing practice-oriented test procedures and standards. They include the off-set crash test, for example, first conducted in 1973. It is based on the realisation that the cars collide with only a one-sided and not a complete overlap of the vehicle fronts in about three fourths of all head-on collisions. The 55-km/h head-on crash test with 40-percent overlap against a rigid barrier was one of the toughest test conditions for the body shell structure for a long time, and not just for that of a #MercedesBenz passenger car. The rigid barrier was replaced by a deformable one. The reason being that accident research had shown that such a barrier as well as a test speed adjusted upwards reproduce real accidents even better.
