Car to Car or Car to X technology represents the future of the automotive world, as this advanced technology enhances safety and security, increases traffic fluidity and reduces accidents, by exchanging cars. Information together and infrastructure on the road.
Professor Horst Fecker, from the Saarland University of Applied Sciences, explained that cars equipped with this technology are equipped with a type of router that can send and receive data even when traveling at high speeds, and the German Professor stressed that the range of coverage of the router - which is 100 meters - meets most uses within the cities.
Safe WLAN standard
These cars send messages every second by means of the safe "WLAN" standard. These messages include information about speed, location and direction, and data about the vehicle's control operations such as severe braking or activation of the warning lights set is transmitted.
In the case of "Car to x" communication technology, communication is not only about cars, but cars "talk" to the traffic infrastructure.
In addition to enhancing safety and security aspects, this information increases traffic fluidity, as traffic lights can tell cars in real time about speed, which helps in saving fuel and reducing accidents.
With more network connections available, this system can warn drivers in advance of sightings or cyclists when cornering or before entering intersections.
ETSI G5 Standard
"The Volkswagen company relies in its communications on the ETSI G5 standard, which is used by many other companies, including the companies producing traffic lights or the Austrian company for infrastructure (highways and charging) Transit)".
For his part, Professor Andre Seck of the Federal Road Research Institute pointed out that "the more cars equipped with Car-to-Car or Car-to-X communications technology, the better the warnings are transmitted," and then the system can reduce the number of dangerous accidents.
Experts expect that it will take 17 years until the market is covered by 100% of the cars equipped with this technology, but the supply of 10% to 15% of the cars only is sufficient to cause positive effects on traffic, and this can be achieved within three to four years If all companies supply their new models with this technology.
Volkswagen Golf
Volkswagen introduced its new Golf icon and equipped it with Go To X technology for the first time. The advantage of this technology is to make direct contact in real time in a few parts of a second, in addition to that it does not cost motorists any additional fees, given Because the communication does not take place via the telephone network.
Thomas Pele, a developer at Volkswagen, explained that golf cars communicate with each other and warn each other in cases of breakdowns, accidents, traffic jams, emergency braking and unstable driving conditions.
Safe cloud service
There is no consensus on the best telecommunications standard yet, and Mercedes has been relying since 2016 on network communication technology, which directs vehicle information to other Mercedes vehicles via a secure cloud service.
"Through the data, we have created an extended sensor that can travel the road several kilometers in front of the car," said Nicholas Kleiner, a developer at Mercedes.
Cars do not need any special devices or components in order to share information with the other group of cars, but the vehicle must be equipped with a navigation device and the LiveTraffic function be activated.
Connected Drive
The German company, BMW, has been adopting a similar path and has been adopting internal communications technology since 2016 through the "Connected Drive" system, which alerts the driver to specific driving situations.
Joachim Gotel from BMW Company explained that the system communicates with the data that is transferred from cars for long distances through the company's servers to other cars, and therefore the importance of this information is not limited to warning other cars within a distance of a few hundred meters, but a distance that extends to Several kilometers.
The German company announced the use of the new data standard "5G" in its iNext car, starting in 2021, which allows the ability to send and receive data in short distances.
In contrast to Volkswagen, BMW is dependent on C V2X mobile technology and LTE in 2017, and there are many other car companies that rely On this standard to develop their own systems.
BMW is seeking to develop a platform through which safety data can be shared between carmakers and road users, and BMW has cooperated with Daimler, Ford, Volvo, and HERE and TomTom. A few months ago, a neutral "server" was launched to share safety traffic data.
