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 (S1); - generating environmental situation data , which describes at least one current relative arrangement of at least one different motor vehicle 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 (S2); - 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 (S3); - receiving at least one further vehicle environmental map from the respective at least one different motor vehicle in the environment of the motor vehicle (S4); - combining the at least one received vehicle environmental map 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 (S5); - providing the generated current local environmental state map in the motor vehicle (S6), wherein, upon application of the map data evaluation criterion , it is examined if a respective motor vehicle described by the received vehicle environmental map is also described by the generated vehicle environmental map , and if at least one additional motor vehicle is described in the respective received vehicle environmental map , which is absent in the own vehicle environmental map , the at least one additional motor vehicle 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 if a higher reliability value is associated with at least one data packet underlying the received vehicle environmental map 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 (S1); - generating environmental situation data , which describes at least one current relative arrangement of at least one different motor vehicle 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 (S2); - 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 (S3); - receiving at least one further vehicle environmental map from the respective at least one different motor vehicle in the environment of the motor vehicle (S4); - combining the at least one received vehicle environmental map 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 (S5); - providing the generated current local environmental state map in the motor vehicle (S6), <EOS>
