With the world’s first public crash take a look at involving two totally electrical automobiles, Mercedes-Benz goes above and past not solely the authorized necessities but additionally these of the scores trade. Euro NCAP stipulates a frontal influence take a look at utilizing a 1,400 kg trolley with an aluminium honeycomb barrier replicating the entrance of one other automobile.
In accordance with the specs, the take a look at automobile and the trolley collide with an overlap and at a velocity of fifty km/h. Mercedes-Benz, nonetheless, used two actual automobiles, an EQA and an EQS SUV, that are considerably heavier at round 2.2 and three tonnes respectively. As well as, each fashions had been quicker, every going 56 km/h, which meant that the general crash vitality was significantly increased than required by legislation. The automobiles’ intensive deformation following the collision could appear alarming to the non-expert.
For the Mercedes-Benz engineers, nonetheless, it reveals that the automobiles had been in a position to successfully take in the vitality of the collision by deforming. Consequently, the passenger security cell of each electrical fashions remained intact and the doorways might nonetheless be opened. In an emergency, this may make it doable for occupants to exit the automobile on their very own or for first responders and rescue personnel to achieve them. The high-voltage system within the EQA and the EQS SUV switched off robotically in the course of the collision.
The crash take a look at on the Group’s Know-how Centre for Car Security in Sindelfingen demonstrates Mercedes Benz’s real-life security philosophy: To make vehicles that maintain up not solely in outlined crash take a look at situations, but additionally in real-life accidents. The take a look at situation involving a velocity of 56 km/h and 50 p.c frontal overlap corresponds to a sort of accident frequent on rural roads, for instance throughout a failed overtaking manoeuvre. The velocity chosen for the take a look at takes under consideration that, in a real-life accident, the drivers would nonetheless attempt to brake earlier than the worst case of a collision.
“Security is a part of Mercedes-Benz’s DNA and one among our core commitments to all street customers. And to us, defending human lives is just not a query of drive system. The current crash take a look at involving two totally electrical automobiles demonstrates this. It proves that every one our automobiles have an equally excessive stage of security, it doesn’t matter what expertise drives them. We’re working onerous to attain our imaginative and prescient of accident-free driving, which works past the “Imaginative and prescient Zero” aims set by the WHO and the United Nations Regional Commissions. We don’t simply need zero visitors fatalities by 2050 and a halving within the variety of visitors fatalities and severe accidents by 2030 in comparison with 2020. Our objective by 2050 is zero accidents involving a Mercedes-Benz automobile,” says Markus Schäfer, Member of the Board of Administration of Mercedes-Benz Group AG, Chief Know-how Officer.
The EQA and the EQS SUV every carried two grownup dummies – a complete of three females and one male. Evaluation of the as much as 150 measuring factors per dummy point out a low threat of great to deadly damage. Which means that the outlined crumple zones and superior restraint programs in each automobiles provide excellent safety potential for the occupants in a crash of this severity. All security gear, resembling airbags and belt tensioners with belt power limiters, labored as meant. The crash take a look at thus confirmed the outcomes that the engineers had beforehand calculated in quite a few laptop simulations. Actual-life automobile testing at all times additionally serves as a last comparability with the simulations. Moreover, the crash take a look at clearly reveals that compatibility (i.e. the interplay of the deformation constructions of various automobiles concerned in an accident) is a part of the security necessities for Mercedes-Benz vehicles.
One other focus of the crash take a look at was the kind of dummy that the security specialists positioned within the driver’s seat of each automobiles – the Hybrid III fifth Percentile Feminine, which is the feminine dummy at present used within the automotive trade for frontal collision exams. It corresponds to a lady of roughly 1.5 metres tall and weighing round 49 kilograms. In response to the underlying statistics, solely 5 p.c of girls worldwide are smaller or lighter. For a few years, Mercedes-Benz has used frontal crash exams with fifth percentile feminine dummies within the entrance seat to design its safety programs for the widest doable vary of shoppers. Rankings by shopper safety associations in addition to numerous authorized necessities worldwide now embody specs for testing with fifth percentile feminine dummies. One other fifth percentile feminine was a passenger within the EQA. Within the passenger seat of the EQS SUV was a Hybrid III fiftieth Percentile dummy, representing a 78-kilogram male of common top.
Mercedes-Benz has developed a multi-stage high-voltage safety idea for its electrical automobiles. The system has eight key components to make sure the security of the battery and all parts with a voltage above 60 volts. Examples embody separate constructive and unfavorable wiring and a self-monitoring high-voltage system that robotically switches off within the occasion of a severe collision. In lots of instances, the corporate’s excessive inside security requirements exceed the authorized necessities or these of shopper safety organisations. Mercedes Benz has impressively demonstrated this as soon as once more with the most recent crash take a look at.
A brand new marketing campaign on electrical automobile security focuses on the groundbreaking frontal crash involving the EQA and the EQS SUV. The marketing campaign reveals the cut up seconds of the crash, which lasts not than the blink of an eye fixed, in tremendous sluggish movement. What actually issues on this fraction of a second throughout an accident is that every one security programs work collectively in a coordinated method at simply the appropriate time to guard life as greatest as doable. This interplay of all security programs and ideas is sort of a classical symphony. Right here, too, the proper concord of all components creates one thing really nice. That’s why the brand new marketing campaign movie is entitled “Security Symphony”. In an unprecedented method, it visualises artistically how the totally different security programs work collectively as one at simply the appropriate time.
The movie and quite a few associated property will seem on all Mercedes-Benz social media channels later this 12 months with the hashtag #allforsafety. The goal group and channel-specific property vary from video clips and interactive quizzes to an informative documentary in regards to the crash take a look at of the EQA and EQS SUV.
Since 2016, Mercedes-Benz has been conducting crash exams on the new Group-owned Know-how Centre for Car Security in Sindelfingen. The take a look at centre is likely one of the largest and most fashionable of its form on this planet. It has three extremely versatile crash lanes main into a big, support-free space measuring over 8,000 sq. metres (90 m × 90 m). Its capability can be spectacular: In Sindelfingen alone, Mercedes-Benz conducts as much as 900 crash exams and 1,700 sled exams yearly.
The model with the star has over 60 years of expertise with crash exams. Together with evaluation by the Group’s Accident Analysis unit, this expertise types the idea for the real-life security philosophy. Based in 1969, the Accident Analysis unit analyses accidents involving fashionable Mercedes-Benz automobiles. The intention is to grasp how accidents occur and which security programs might have prevented them or diminished their severity.
