Further, the aim of the present invention is to provide a method for establishing an improved traffic information, warning and/or guiding system in a vehicle-to-everything environment with improved functionality, convenient applicability, wide range, easy connectivity and enhanced safety. Also, the aim of the invention is to provide a corresponding traffic server. Besides, the aim of the invention is to provide an improved a traffic information, warning and/or guiding system in a vehicle-to-everything environment. Further, the aim of the invention is to provide a computer program product for a corresponding method.

According to the first aspect, embodiments of the invention provide a method for establishing an improved traffic information, warning and/or guiding system in a vehicle-to-everything environment with the features of the independent method claim. According to the second aspect, embodiments of the invention provide a traffic server with the features of the independent device claim. According to the third aspect, embodiments of the invention provide a traffic information, warning and/or guiding system in a vehicle-to-everything environment comprising a corresponding traffic server with the features of the independent system claim.

According to the fourth aspect, embodiments of the invention provide a corresponding computer program product for a respective method with the features of the independent product claim. Details and features disclosed on individual aspects of the invention also apply to the other aspects of the invention and vice versa.

According to the first aspect, embodiments of the invention provide a method for establishing a traffic information, warning and/or guiding system (may also be called only system) in a vehicle- to-everything environment (which method may further preferably be used for organizing, controlling, supporting, assisting, relieving, rerouting, protecting and/or supporting traffic in such a system), the method comprising: providing a traffic server for supplying traffic services (especially comprising information, organization, control, support, relieve, reroute, protection and/or assistance services) to at least one vehicle in the vehicle-to-everything environment, collecting (especially comprising at least receiving, determining, measuring and/or predicting) a traffic information at the traffic server, evaluating (especially comprising processing, verification, consolidation, adaptation and/or refining) the traffic information by the traffic server, transmitting a message containing an evaluated traffic information from the traffic server to the at least one vehicle.

Embodiments of the method may be carried out in the given order or in a modified order. Individual actions of the method may be carried out simultaneously and/or repeatedly to allow a flowing process.

A traffic server within the meaning of the invention is a computer or a group of computers providing a high computational power, a large memory and easy access to updates as well as to different sensor data, environment data and/or weather data in order to provide a reliable and accurate traffic information that may be used by the at least one vehicle and preferably by many or even all participants of the vehicle-to-everything environment. The backend device within the meaning of the invention is the representative of the cloud.

A traffic information within the meaning of the invention may comprise row or processed sensor data, road condition data, traffic signs data, traffic news data, traffic events data, environment data, weather data and so on, that is several data which may be relevant for a traffic information. Preferably all data as well as all data sources relevant for traffic information may be collected, considered and evaluated (especially comprising processing, verification, consolidation, adaptation and/or refining) by the traffic server for providing a reliable and accurate traffic information that may be used by the at least one vehicle and preferably by many or even all participants of the vehicle-to-everything environment.

An evaluated traffic information serves as a reliable and accurate traffic information that may be used by the at least one vehicle and preferably by many or even all participants of the vehicle- to-everything environment.

The idea is to provide a third party server as a central traffic server which collects several data of various sensors, sources, applications and/or techniques for collecting data, which may be relevant for a traffic information. Preferably, the traffic server may use various methodologies for analyzing data by evaluating a traffic information, combine them or their results and/or verify the results and/or compare the results with the actual traffic situation. Thus, a reliable and accurate traffic information may be centrally provided, especially independently of vehicle brand, sensor equipment, methodologies and technics. After evaluation a reliable and accurate traffic information may be distributed within the vehicle-to-everything environment to all participants of traffic services, especially independently of V2V technologies for connection of the vehicles, preferably by commonly used techniques, like radio waves or Bluetooth. Moreover, warnings may be provided to increase safety in traffic. Also, recommendations may be provided to vehicles how to act according to the current traffic situation.

With other words the idea is to provide an improved traffic information, warning and/or guiding system in a vehicle-to-everything environment. The system may use a vehicle-to-vehicle environment of interconnected cars of different brands, preferably build by generally accessible technology, to guide and to warn one another. Through the integration of third party services/applications by providing traffic information in a vehicle-to-everything environment a centralized provider for improved traffic information may be created for all participants. Thus, the road accidents may be minimized and even avoided. Further, participants may be provided with the ability to assess the message, to forward the message along their way according to the assessment, to confirm receiving and/or accuracy of the evaluated traffic information. The conformation may be provided for example by voice command.

For example, if all the vehicles of different brands on a road are connected and they integrate a third party service, then they may easily share the evaluated traffic information amongst themselves without a need to adapt it to a different technology.

The evaluated traffic information may further include time to destination, traffic jam information along the route, traffic signs/traffic sign recognition, road works, emergency info, conditions of the road or hazard info along the route (icy road, snow on road, flood, reflection road, oil on road, objects on road etc.), and so on.

The warning system may provide messages with an audio/video/augmented/haptic feedback, for example steering vibration for 2-3 sec.

Preferably a private or local network, preferably a mesh network, may be formed by the traffic server through the at least one vehicle with nearby vehicles over a certain distance and/or along the road. This private or local network may be used to integrate third party services and/or to exchange the evaluated traffic information.
