A comprehensive analysis of the E class LED intelligent lighting system for Mercedes Benz

The easy train is in the car circle, dare to take his own car light to say something is really not a few. Audi is one of the "lamps and lanterns factory", and the angel eye of BMW has been enjoyed by people. Mercedes Benz, past the old "four eyes" light design, it is difficult to arouse people's praise for the Mercedes and Mercedes. However, with the arrival of the new generation of Mercedes Benz family, the Mercedes Benz is removed from the "eyes", and the world is bright with a bright face. Not only that, the Mercedes also added more wisdom to his eyes. What do they all have?

After the Benz brand new S level, the Mercedes Benz E class also has a full LED lamp design (luxury version), including two LED daytime traffic lights, 8 LED steering lights and LED near light light. According to the introduction, the Mercedes Benz adopted the LED energy saving lamp with a power of only 34W. The traditional halogen lamp needs 120W, and the xenon lamp also has 84W. Thus, it can be seen that the energy saving effect of LED is very significant.

Functional introduction

In addition to beauty and energy saving, the Mercedes also assembles the intelligent lighting system and the adaptive light lamp auxiliary system for the new E level headlights. These two configurations are also from the new S level. Before we carry out the measurement, let us first introduce these two functions in theory.

Although some exaggerated and ridicule means, the intelligent lighting system invented by Mercedes Benz is the first in the industry. As a matter of fact, the system, which was introduced in 2006, is a lighting system that provides five different luminescent modes with a double xenon light bulb as the light source. Now, after 9 years of evolution, the system has been fully converted to LED light source. The five modes of luminescence correspond to urban roads, highways, and are combined with enhanced fog lamps, elbow auxiliary lighting and active turning lighting.

Rural lighting

It can brighten the driver's side of the road, making it easier for drivers to judge the road conditions in the dark, and to be able to react more easily when other vehicles or people travel through their path.

Expressway lighting

When driving on the freeway at night, when the speed reaches the predetermined speed, the brightness of the LED lamp will increase by 60% more than the traditional mode of light. And divided two gear: at 90 kilometers per hour, an automatic activation can effectively improve the distance vision of the night freeway. When the speed exceeds 110 kilometers, the two gear is enabled, the lighting range is further enhanced, the recognition distance is increased again, the visibility of the cone center is more visible than the traditional mode. Increase 50 meters.

Enhanced fog lamp

In the fog (haze also applicable) weather, the function is within 70km/h speed and is activated when the rear fog lamp is opened. The driver's side LED lamp can rotate about 8 degrees and reduce the height of the light, in order to better illuminate the near side of the road, but also to lighten the glare of the reflecting lamp in the fog. The model will automatically shut down at a speed of more than 100 kilometers.

Active turning lighting

According to the different speed and steering angle, the active turning lighting will be automatically opened. At this time, the active lamp can swiftly turn in the direction of the turning (up to 15 degrees), and the lighting effect of the direction of the turning angle is about 90%.

Elbow auxiliary lighting

When the speed is lower than 40km/h, when turning the steering wheel or using a turning signal, the lighting function of the bend will be automatically activated. This will illuminate the area of about 65 degrees in front of the front of the car, about 30 meters away. Compared to the traditional car lamp technology, the pedestrian crossing the road can be found earlier.

In addition to the above five lighting modes, Mercedes has also introduced the function of the Adaptive Highbeam Assist Plus for the new E level. The system can realize the long light light in the lasting lighting, and can effectively avoid the glare interference to other vehicles or pedestrians. Through the front stereo multi-function camera detection, the LED lamp group will automatically press the light down to the front or under the vehicle under the control of the ECU, so that other vehicles are not affected by the light light. According to the different traffic flow and road lighting conditions, the distance of the far light can extend from 65 meters to 300 meters.

A measured Mercedes Benz E enhanced adaptive light lamp system

Before it is measured, let's get a rough understanding of the role of an enhanced adaptive light lamp through a few diagrams.

As you can see, the Mercedes Benz's enhanced adaptive light light system is not only limited to a single vehicle, but two same vehicles appear in the above, and the system is equally applicable. The reason is that, as long as the camera recognizes the light source to enter the light range, the system will automatically adjust the lighting layout and cover the LED light source in the front of the vehicle, so that other vehicles are not affected by the long light light. Let's formally enter the test link below.

In order to make people more intuitive to feel the difference between Mercedes and Mercedes, we first carried out the image of the human body. The purpose is to be able to distinguish between a light light area and a near light lamp in the next test. Of course, we will also do the corresponding marking on the map, well, the real car test starts.

When the car is coming to the front or there is a vehicle ahead, the part of the light source of the LED long light module automatically closes and each forms a "U" type of dark light mode. The light lamp will continue to illuminate the other areas of the road (part of the light light). If it is identified to be driving on the highway and choosing a freeway light, the adaptive light lamp auxiliary system will enable a part of the light light function suitable for the freeway according to the traffic condition. This targeted lighting mode avoids the dazzling of other road users. However, it should be noted that the model can be activated only at a speed of more than 30 kilometers per hour and the environment is in a dark state.

As the world's oldest car life brand, Mercedes always gives people a sense of maturity and stability, but also once appeared "old and old", "old and old" and other disharmonious voices. However, with the advent of the new S level, the new generation of Mercedes Benz family design elements subvert this traditional view. If the new generation of Benz is 10 years younger than the old Mercedes, then at least 8 years of credit is due to the headlight design. It also gives a lesson to people who laugh at the Mercedes and do not understand the design - ginger or old hot!
