Car-to-X Communication
Car-to-x communication is the wireless exchange of information between vehicles and between vehicles and transport infrastructure.

In Germany, the simTD research project (Safe Intelligent Mobility - test field Germany) is examining the everyday practicality of Car-to-X communication under the direction of Daimler. simTD uses wireless technology based on the conventional WLAN standard and integrates UMTS and GPRS mobile technologies to enable any vehicle to generate and transmit important information for the traffic on the road.
The use of such car-to-X communication will greatly expand a vehicle’s visual field, the “telematic horizon”, by enabling vehicles to communicate with each other and with fixed transmission stations to improve local traffic flows.
For example, simTD provides an early warning about the end of a traffic jam over the crest of a hill, notifies the driver of vehicles he cannot yet see in blind side roads or reports black ice on bridges before the danger zone is reached. As well as safety-related applications, convenient functions such as suggested routes to the next free parking space can be implemented. Conversely, vehicles can send signals to traffic signal systems so that they can adapt their switching behaviour to the current traffic volume. This enables traffic flows to be organised more efficiently - quicker, more safely and with less stress. | ||||||||
