A method for validating information, wherein a first information item is detected essentially continuously, at least for the duration of its relevance, by a vehicle-to-X communication device, wherein a second information item is detected at the same time as the first information item by at least an individual sensor or a group of sensors, wherein the at least one individual sensor or the group of sensors is coupled at the data level to the vehicle-to-X communication device and wherein the first and/or second information items are validated by reconciling an information content of the first and second information items in the case of corresponding information content. The method is distinguished by the fact that the second information item is detected in an essentially discontinuous fashion.

Method and system for validating information

By reducing the packet size for C2X data transmission, it is possible to increase the transmission range and the number of transmitted data packets per unit time. By way of example, only component information items are transmitted, which can be converted into a full information item by the receiver using supplementary information items that come from a different source. In order to obtain the full information items, it is possible to utilize firstly transmission properties of the radio medium and secondly common information bases as determined by the system.
