Method, system and infrastructure system for supporting at least partially automated driving, at least partially automated guided vehicle

According to a first aspect of the invention, in particular at a non-intersection, for example before a tunnel entrance, a method for supporting at least partially automated driving in the region of a driving road section supported by a light signaling device is proposed. According to the invention, a V2X message is sent by means of a roadside unit (also referred to as a "roadside unit" or "RSU") of the infrastructure system, said V2X message comprising information about the current state of at least one light signaling device of the infrastructure system, in particular an SPAT message and subordinate map data. The V2X message is received by at least one at least partially automatically guided vehicle comprising a communication control unit. According to the invention, both the infrastructure system and the at least partially automated guided vehicle are provided to identify an error of the infrastructure system on the basis of not sending and/or not receiving a V2X message, or on the basis of the reception o
