Car-to-car and car-to-infrastructure communication technology research is on the rise, but it has reached a new high with the announcement of a major real-world test taking place in Germany. Commonly referred to as car-to-X communication, inter-car and inter-infrastructural networks are being studied by a number of automakers for a variety of safety- and driver-assistance-related uses. The basic idea: Cars that can talk to one another as well as the infrastructure they interact with will make for a safer and more informed driving environment. (For example, GM most recently announced that it is looking to tap into short-range Wi-Fi networks to help its pedestrian-detection systems determine the location and trajectories of pedestrians via their cell phones.) The test is happening in and around Frankfurt, Germany, and is backed by a consortium of automakers, tech institutions, and government agencies operating under the SimTD banner. It will involve a fleet of 120 cars operating on actual roads until the end of the year.
Included in the 120-car fleet will be specially equipped Audi A4s, BMW X1s, Ford S-Maxes, Mercedes-Benz C-classes, Opel Insignias, and Volkswagen Passats. SimTD’s public-road–based test will be used to gather data on the effectiveness of car-to-X–enabled technologies such as:
- Electronic Brake Light: When a car brakes, it sends a signal to any cars behind it; this way, drivers in following cars are informed of the braking event ahead of them during inclement weather, low-visibility situations, or even if the view ahead is obstructed by a hill or curve.
- Traffic Management: Cars monitor traffic situations and feed data such as speed or stoppages to other cars.
- Obstacle Warning: Like traffic management, obstacle warning serves to alert other drivers of road obstructions or dangers.
The real-world test is essential for finding out more about car-to-X’s crowd-sourced update capabilities, which could influence future driver-warning systems. But besides potentially helping drivers make better decisions, the tech’s effectiveness also has significant ramifications for the future of autonomous vehicles and semi-autonomous active-safety systems. That’s because in addition to offering crowd-sourced updates on roadway conditions, another aspect of car-to-X tech involves cars identifying the location and behavior of other cars around them. Volvo is putting this functionality to use in its road-train research, while BMW is using it to help bad drivers turn left. It’s not a huge jump from the aforementioned Electronic Brake Light, giving drivers a heads-up that they need to brake, to the computer disregarding the driver completely and automatically applying the car’s brakes—many cars already do this using radar and some software code.

Not to sound too alarmist to driving enthusiasts, but car-to-X very much is yet another stepping stone toward autonomous vehicles becoming a reality. But on the upside, it also has the potential to help save your tuchis in a jam. So there’s that, which is nice.
