Description

Method for determining the usefulness of data for road traffic-related functions The present invention relates to a method for determining the usefulness of data for road traffic-related functions. Furthermore, the present invention relates to a station, a computer program, and a storage medium for this purpose. The structure of vehicle-to-everything (V2X) messages is determined by standard development organizations (SDOs), including the European Telecommunications Standards Institute (ETSI) or the Society of Automotive Engineers (SAE International). Specific V2X messages, such as CAM [Cooperative Awareness Message, ETSI], VAM [VRU Awareness Message, ETSI], CPM [Collective Perception Message, ETSI], or BSM [Basic Safety Message, SAE], have already been standardized. Currently, V2X data can typically be derived from cluster-based outsourced information. Additionally, the driver is responsible for responding to V2X information and determining the need for action, such as gradual deceleration based on collision warnings. Due to the lack of robust safety attributes, the vehicle cannot directly use V2X data for safety-critical driving actions, such as initiating sudden braking (Automatic Emergency Braking, AEB) or steering. The development of safe CAD systems [CAD: Cooperative Automated Driving] focuses primarily on building comprehensive systems where safety is embedded in the overall concept. Such systems may be described as safe "closed world" environments where both the transmitter and receiver adhere to the same safety concept and homologation. These environments may also be tailored to specific use cases. An example of such a system is Automated Valet Parking (AVP), which may currently be in the standardization phase at ETSI. In a disadvantageous way, whenever a new vehicle is developed, entirely new homologation may be required for every conceivable combination of garage/vehicle AVP pairs to ensure safety for all possible combinations. US2021219139 A describes a method for increasing the reliability of received V2X data by including transmitter-side metadata, such as vehicle manufacturer, technical equipment, vehicle year, hardware and software implementation details, and the authentication level of the transmitting vehicle, in V2X messages. WO2022/122450 A1 describes including a "safety section" in V2X messages to enable its usefulness for safety-related driving functions. The safety section may include a safety level, failure rate, development process indication, validity period, error model, and/or reliability of the V2X data. US20230059220 A1 describes a method for validating the validity of received V2X messages by comparing the data of the received V2X messages with the same data from other sources (e.g., objects detected by onboard sensors, validity of transmitter location using RSSI, previous V2X messages). The stated objective is solved by a method having the features of claim 1, a station having the features of claim 9, a computer program having the features of claim 10, and a computer-readable storage medium having the features of claim 11. Further features and details of the invention are disclosed in the dependent claims, description, and drawings. Features and details described in relation to the method according to the invention also apply to the station according to the invention, the computer program according to the invention, and the storage medium according to the invention, and vice versa, and thus may always be referenced to one another in relation to disclosures concerning individual embodiments of the invention. The objective is addressed by a method for determining the usefulness of data, particularly for road traffic-related functions, said method comprising the following steps, namely - A step of receiving a message for a road traffic-related function of a station at a station, wherein the message includes data, in particular measurements and/or estimates, and metadata, and the metadata includes information about the data related to the road traffic-related function; - A step of analyzing data for road traffic-related functions based on an evaluation of metadata, wherein the evaluation includes checking whether the received data of a message satisfies at least one requirement of a road traffic-related function; and - Includes a step of determining the usefulness of data for road traffic-related functions based on the analysis step. This can, preferably, improve the more efficient evaluation of received messages. Additionally, this potentially prevents the occurrence of risks, for example, in relation to road traffic-related functions. Furthermore, this has the advantage that the method according to the present invention supports more effective decision-making, for example, regarding whether data within a received message satisfies the requirements of a road traffic-related function executed at a receiver station. Additionally, the method according to the present invention can im
