4.6.2019 Stuttgart/Eindhoven. Together for more safety in road traffic: Daimler, BMW, Ford and Volvo are testing in co-operation with HERE Technologies, TomTom, as well as the transport authorities in six European countries, such as information on acute risk situations in real time via Car-to-X technology to share.
The project partners have signed yesterday in Eindhoven, the Netherlands a Memorandum of Understanding (MoU). The experimental phase is designed to last for twelve months and starts in the Netherlands.
How the Information can be a sudden danger – for example, freezing or accident as quickly as possible to the following or oncoming road users to pass on? Daimler already uses since 2013, the standard technologies of mobile networking, to convey hazard information from vehicle-to-vehicle (“Car-to-Car”). Now leading OEM and navigation services to work first on a common, manufacturer-independent and EU-wide solution. The traffic and transport ministries of Germany, Spain, Finland, Luxembourg, the Netherlands and Sweden support the project. The aim of the today launched the pilot project is to explore technical, economic and legal questions about “Car-to-X” more. Car-to-X communication between vehicles and with the transport infrastructure.
Sajjad Khan, Executive Vice President, Member of the Divisional Board, Mercedes-Benz, CASE: “Car-to-X communication has the potential to increase safety on the roads significantly. With this project, we highlight the current approaches to a new level: for the First time, many performance and range of distribution partners on Board, so that hazard information will reach almost in real time, a large number of traffic participants. This can save lives. The Foundation for this development has laid Daimler already years ago: The Mercedes-Benz vehicles already have the technology, the information is for a comprehensive and secure exchange of safety-ceiling-related traffic is necessary.“

In line with EU targets
The focus of the project is safety-related traffic information – at the EU level under the heading of “Safety Related Traffic Information” (SRTI) wants to discussed be. With their Initiative, the project partners support the efforts of the EU Commission, in the development of networked and intelligent transport systems forward. Long-term goal of the EU is to reduce the number of deaths and serious injuries in road transport up to 2050 significantly. Improved information flows could contribute to this considerably.
In the EU-regulation 866/2013 is determined, inter alia, that a minimum level of General for road safety-related traffic information to all users as possible, free of charge. The agreement signed today is based on this political base.
The project partners are set in principle on a technology-open testing and development of the flows of information through Car-to-X technology. For the pilot project which is already built-in, mobile radio-based communication systems are used. These are tried and tested and ready to use.
The flow of data: How the information is delivered
After the signing of the Memorandum of Understanding in the framework of the ITS European Congress in Eindhoven, the project partners have demonstrated an example of how the dissemination of the information via Car-to-X communication works. Three scenarios illustrated the transmission of information. Here, a “channel simulated in each case” of a breakdown or emergency situation:
Scenario 1: The driver of a Mercedes-Benz vehicle is actuated, the flashing hazard lights.
Scenario 2: The driver of a BMW vehicle via the on-Board system, emergency call (“eCall”).
Scenario 3: A traffic authority to inform you about a sudden danger in the environment, such as a wall construction site.
The two station vehicles were positioned along a route from the centre to the Evoluon Congress Center in Eindhoven. The “Receiver vessels” – test vehicles of the brands Mercedes-Benz, BMW, and Ford went along this path and simulated as following or oncoming cars in a critical traffic situation. Immediately after the first pulse in the channel receiving the
The occupants of the recipients of the vehicles on the on-Board system a note.
The principle of data transmission works as follows: Each of the actions puts a pulse and thus the data flow in motion. A message from the Sender – i. e. the vehicle or the transport authority, on an anonymous basis and, in General, mobile radio based transmitted to a so-called “Aggregator”. This role, for example, the experts for navigation systems, TomTom and HERE.
Under real conditions, the Aggregator collects the information and brings them together, until a critical number of messages is reached. Then a “Service Creator is composed of the “Aggregator””: He creates a warning message. About the navigation system or the communication systems provided by the car manufacturer, this warning is sent to the recipient vehicles that are in the vicinity of the Danger. Due to the high market penetration of the parties, navigation services can thus set a large number of road users at an early stage of an acute danger situation.
Objectives and limits of testing: data security in the focus
The subject of the investigation will be in the next twelve months, among other things, issues of data compatibility and cloud-based data processing. The companies involved in the use of the currently installed communications technologies and file formats, and develop them in the next step, if necessary, and to harmonize. The cooperation of the project partners starts in the Netherlands and will gradually be extended to other EU countries increased.
The security of the data at any stage of the project a top priority. The flow of information takes place for the period of the pilot project within a closed “Ecosystem”, to which only project partners can access. Daimler uses for the project, only the test fleet, customer data will not be collected. In addition, the involved Mercedes-Benz vehicles, send all of the data in anonymised Form: Each message contains only the Information for the event and a time stamp. A reference to the transmitter vehicle can not be produced.
Background: Car-to-X technologies at Daimler
Daimler brings to the collaboration project a high level of Expertise to Car-to-X technologies. As the first automotive manufacturer in the world Mercedes-Benz 2013 vehicle-to-vehicle communication in a series of vehicles put on the road. Since 2016, the Car-to-X communication modules in series are installed, initially in the E-class, now available in all Mercedes-Benz vehicles with navigation system.
For more than ten years, Daimler is also involved in research projects on the topic: among other things, the largest field trial for Car-to-X communication “sim TD – Safe and Intelligent mobility – test field Germany”. From 2008 to 2013, 500 participants have placed more than 1.6 million kilometres, in order to investigate the contribution of intelligent communication systems to improving traffic safety and mobility. In this project, Daimler has worked with other automotive manufacturers and suppliers together. It could be shown that Car-to-X functions significantly increase the safety during the travel. Therefore, environmental pollution can be eliminated by a more efficient use of the transport routes to avoid, according to the researchers. Networked, intelligent communication systems might contribute crucial.
