The ninth-generation Mercedes-Benz E class features a new lighting technology from Germanys Hella KGaA Hueck & Co.
The optional system, which Mercedes calls Adaptive Main Beam Assist (Adaptive High Beam Assist in the United States), causes the E-class headlamps to automatically switch from high beams to low beams when another vehicle is detected.
A windshield-mounted camera views the road ahead and passes the data to image-processing software.
The high-beam assistant starts working at speeds of more than 55kph and automatically switches the headlamps to low beams when another car is less than 800 meters away.
When switching to low beams, the system makes sure that the illumination angle is adjusted to prevent temporarily blinding the driver ahead while still providing as much light as possible for the road ahead.
Tests showed that the high-beam assistant makes traveling at night safer. For example, roadside pedestrians were visible at a distance of about 260 meters, compared with 110 meters for the conventional low beam.
Another E-class safety feature comes from Rehau. The German suppliers bumpers have crash sensors that trigger the cars hood to pop up a couple of centimeters if the car hits a pedestrian. By raising the hood there is more so-called crush space between the pedestrian and the hard parts under the hood such as the engine and radiator. This is supposed to increase the pedestrians chances of surviving the collision.
Delphi provides direct-acting piezo injectors for the E-class highest performance diesel engines. The piezo injectors physical properties allow their thickness to be adjusted in nanoseconds by applying an electrical current. Unlike conventional systems, the injector needles are operated directly by the piezo, enabling them to spray fuel into the combustion chamber faster and more accurately, thereby improving combustion and reducing emissions.
