MERC DEVELOPS CARS THAT TALK TO EACH OTHER



The Mercedes-Benz stand at the 15th World Congress on Intelligent Transport Systems (ITS) highlighted vehicle-to-vehicle and vehicle-to-infrastructure communication systems, technologies for monitoring vehicle surroundings, and systems for measuring driver stress. Mercedes-Benz also used the occasion of the ITS to unveil myCOMAND — the completely Internet-based in-vehicle infotainment system of the future.

With some 10,000 international participants, the ITS World Congress is the world’s biggest exhibition of state-of-the-art information and communication technologies for automotive applications.


Improved Safety Through Vehicle-To-Vehicle Communication

Mercedes-Benz are supporting the Vehicle Infrastructure Integration (VII) initiative, which tests concepts for vehicle-to-vehicle communication as well as communication between vehicles and transmission/ receiving stations along a route.

The technical basis for VII is provided by dedicated short-range communication (DSRC) technology, which enables vehicles to communicate with each other and their surrounding environment. Information obtained via DSRC can make drivers more attentive and enable dangerous situations to be recognised, and, in the ideal case, avoided.


Preventing the Unintentional Running of Red Lights

If a vehicle equipped with the new system approaches a VII-enabled traffic light and the system’s camera-based traffic light recognition unit registers that the light is red, the vehicle receives a DSRC signal containing information on the current state of the light. If the driver continues on toward the red light, he or she is warned by a beep and a symbol on the dashboard display, which give the driver enough time to brake the vehicle before it runs the light. Should the driver fail to react, the next acoustic and visual warning stage is engaged, which still allows the driver enough time to avoid running the light, although harder braking will now be required. If the driver still doesn’t respond, the vehicle itself initiates an autonomous emergency braking manoeuvre, whereby the driver can still overrule the system at any time.


Improved Safety Due to Relaxed Drivers

“Mindlab” is a method developed by Mercedes researchers that uses brainwave measurements to evaluate driver stress, whereby the scientists are also working to determine the best way to issue warnings in such stress situations. Here, electrodes attached to the heads of test subjects provide the scientists with an image of the processes occurring in the individuals’ brains. These images depict the characteristic patterns of brainwaves, which allow experts to determine, for example, how attentive a person is, or how much stress and/or fatigue he or she is currently suffering.

Improved Safety Through Predictive Technologies

Ensuring that assistance systems can effectively support drivers requires precise and reliable analyses of traffic situations. The “6D-Vision” system from Mercedes-Benz uses two cameras that view their surroundings in the same manner that a human being’s two eyes do. This stereo arrangement enables 3D depiction of the vehicle’s surroundings in real time. The system uses this information to identify every object around the vehicle and assess the risk it might pose for a potential collision. The Mercedes researchers are particularly hopeful that the system can be used in the future to significantly reduce accidents involving pedestrians, and also lessen the severity of those accidents that occur nevertheless.

Improved Comfort Through Internet-Based Infotainment System

MyCOMAND is a brand-new infotainment system developed by Mercedes-Benz. As a completely Internet-based application, it offers a preview of the vehicle telematics systems of the future. MyCOMAND uses the Web to continually update all data and information, which it makes available through a single interface. Users can thus access individual services at any time — and in accordance with their current position and situation — via an attractive and intuitive operating system.
