The new EQS SUV: the equipment highlights DIGITAL LIGHT and head-up displays

DIGITAL LIGHT headlamp technology (special equipment) enables innovative functions, such as the projection of auxiliary markings or warning symbols onto the road. Other equipment highlights are the head-up displays, available in two sizes. The large Augmented Reality Head-up Display (AR-HUD) shows relevant information and actions three-dimensionally in the real driving situation. The technology of DIGITAL LIGHT and AR-HUD is known from video projectors.

DIGITAL LIGHT has a light module with three extremely powerful LEDs in each headlamp, whose light is refracted and directed by 1.3 million micro-mirrors. The micro-mirrors occupy the area of a thumbnail. A control unit with a powerful graphic processor uses an HDMI-like connection to generate a continuous video stream to the mirrors.

These assistance functions are special features[1]:

  • Warning of recognised roadworks by projecting an excavator symbol onto the road surface
  • Aiming a spotlight at pedestrians detected at the roadside as a warning
  • Traffic lights, stop signs or no-entry signs are pointed out by projecting a warning symbol onto the road surface
  • Assistance on narrow road lanes (roadworks) by projecting guiding lines onto the road surface
  • Indication of the start of cooperative lane change
  • Warning and directional guidance when Lane Keeping Assist or Blind Spot Assist detects a hazard

The topographic light takes hills into account on the basis of navigation maps, especially crests and dips:

Two different head-up displays (HUD) are optionally available, including an innovative augmented reality variant (AR-HUD) with an especially large image. The opening angle of the display is 10 degrees horizontally and 5 degrees vertically, the image is at a virtual distance of 10 metres (basic HUD: 4.5 metres: This display area corresponds to a monitor with a 77-inch diagonal. The AR-HUD provides extensive augmented reality content for driving assistance systems and navigation information. They blend into the surroundings ahead of the vehicle for the driver, and can therefore contribute to reducing distraction further. The imaging unit consists of a high-resolution matrix of 1.3 million individual mirrors and a highly efficient light source.
