A method for providing a current local environmental state map for a motor vehicle, comprising the following steps in the motor vehicle: - generating own driving situation data describing a current position-relevant vehicle parameter of the motor vehicle by evaluating vehicle data of the motor vehicle; - generating environmental situation data, which describes at least one current relative arrangement of at least one different motor vehicle (34, 35, 36) arranged in a preset environment of the motor vehicle to the motor vehicle, by evaluating sensor data of a sensor device of the motor vehicle; - evaluating the own driving situation data and the environmental situation data for generating a vehicle environmental map, which describes a current local traffic situation in the preset environment of the motor vehicle; - receiving at least one further vehicle environmental map (41, 42, 43) from the respective at least one different motor vehicle (34, 35, 36) in the environment of the motor vehicle; - combining the at least one received vehicle environmental map (41, 42, 43) with the generated vehicle environmental map with application of a map data evaluation criterion for generating the current local environmental state map for the motor vehicle; - providing the generated current local environmental state map in the motor vehicle, wherein, upon application of the map data evaluation criterion, it is examined if a respective motor vehicle (10, 34, 35, 36, 37, 38, 39) described by the received vehicle environmental map (41, 42, 43) is also described by the generated vehicle environmental map, and if at least one additional motor vehicle (37, 38, 39) is described in the respective received vehicle environmental map (41, 42, 43), which is absent in the own vehicle environmental map, the at least one additional motor vehicle (37, 38, 39) is incorporated in the generated current local environmental state map, wherein the own driving situation data and/or the environmental situation data each include multiple data packets and a reliability value is associated with each of the multiple data packets, which describes, how reliable data of the data packet is, wherein upon application of the map data evaluation criterion, it is examined for each received vehicle environmental map (41, 42, 43) if a higher reliability value is associated with at least one data packet underlying the received vehicle environmental map (41, 42, 43) than with a corresponding data packet of the own driving situation data and/or environmental situation data underlying the own vehicle environmental map, and in generating the current local environmental state map for the motor vehicle, only the respective data packet of the data packets respectively compared to each other, with which the highest reliability value is associated, is considered. - generating own driving situation data describing a current position-relevant vehicle parameter of the motor vehicle by evaluating vehicle data of the motor vehicle; - generating environmental situation data, which describes at least one current relative arrangement of at least one different motor vehicle (34, 35, 36) arranged in a preset environment of the motor vehicle to the motor vehicle, by evaluating sensor data of a sensor device of the motor vehicle; - evaluating the own driving situation data and the environmental situation data for generating a vehicle environmental map, which describes a current local traffic situation in the preset environment of the motor vehicle; - receiving at least one further vehicle environmental map (41, 42, 43) from the respective at least one different motor vehicle (34, 35, 36) in the environment of the motor vehicle; - combining the at least one received vehicle environmental map (41, 42, 43) with the generated vehicle environmental map with application of a map data evaluation criterion for generating the current local environmental state map for the motor vehicle; - providing the generated current local environmental state map in the motor vehicle,
