Mercedes Benz: New testing facility for EMC and antenna systems inaugurated
Electromagnetic compatibility (EMC) is a key prerequisite for the future topics connectivity, autonomous driving, shared, and electric drivetrain. With the new test facility, Mercedes-Benz takes an important step as a pioneer in the digitisation of the automotive industry. The new reverberation chamber makes efficient and comprehensive EMC measurements possible. New measuring methods allow vehicle antennas to be measured quickly and realistically. The complex simulation of the global mobile communication services in the new antenna testing hall makes system development in terms of maximum data protection possible. Daimler invested about 50 million euros in the new building at the Mercedes Benz Technology Centre (MTC) in Sindelfingen.
A highlight of the new test facility is a unique reverb (short for reverberation chamber). It allows interference immunity measurements to be conducted there in an especially efficient manner and in particular self-driving vehicles to be tested comprehensively for their immunity to electromagnetic interference.
The reverb houses three large mechanical "stirrers". These spiral reflector structures rotate at speeds of ten or 120 revolutions per minute, which constantly distributes the electromagnetic waves in the room. It is possible to demonstrate that this electromagnetic field distribution is locally equivalent to irradiation with an antenna from all directions.
ART Engineering has produced and delivered the rotating mechanical stirrers.
