Daimler gives its EQ electric vehicle a giant display screen
The Hyperscreen contains three screens that are joined together under a curved cover glass. This cover glass takes shape at 650° Celsius. The glass itself is made of scratch-resistant aluminium silicate, which is extremely break-resistant at a very low thickness. The control electronics for these displays contain 8 CPU cores that access the RAM (capacity: 24 gigabytes) via a fast memory bus with 46.4 gigabytes per second. For haptic feedback during operation, a total of 12 actuators are located under the touchscreen surfaces. If the finger touches certain points there, they trigger a perceptible vibration of the cover plate. The brightness of the screen is adjusted to the ambient conditions using the measurement data from a multifunction camera and an additional light sensor. And because such a large glass in a vehicle also poses a potential risk to occupant safety, the manufacturer has provided an unspecified number of predetermined breaking points as well as five special brackets that can specifically yield in the event of a crash.
In addition to the function display in front of the steering wheel, the MBUX includes a central display and a separate infotainment and control display for the front passenger. The latter two are designed in OLED technology to achieve a particularly high contrast range.
The user interface is designed in such a way that the most important functional areas are directly accessible without having to dive deep into any menus; Daimler calls this level “Zero Layer”. Controlled by AI algorithms, the MBUX system is intended to develop a context-sensitive awareness in which both environmental changes and user behaviour permanently lead to an optimisation of processes. Mercedes-Benz has investigated the usage behaviour of the first MBUX generation. The vast majority of use cases fall into the areas of navigation, radio/media and telephony. The navigation application, with its full range of functions, is therefore always at the centre of the screen unit. The system stores the application preferences of up to seven people.
