A method for reducing the data throughput during the transmission of at least partially variable object-related data between communicating communication modules, and means for performing the method

A method for reducing the data throughput during the transmission of at least partially variable object-related data by means of a protocol between within time conditions via a data transmission device (3; 130) communicating communication modules (10, 20; 111, 112), each having at least one external unit (11 , 12, 13; 21, 22, 23; 121, 122; 123, 124, 125) is assigned to provide or use of the object-related data and the (with a timer 30, 140) are connected, wherein in each case sending communication module (10, 20; 111, 112) a temporal extrapolation of the data to be transmitted taking into account the transmission time and sending the data to the respective receiving communication module (10, 20; 111, 112) is initiated when a from the respective current data and the extrapolated data comparison value formed is reached or exceeded a predetermined size, wherein a respective receiving s communication module (10, 20; 111,112) carried out a temporal extrapolation of each received data using the same extrapolation process and a use of this data in an associated external unit, wherein the received data are respectively used as the basis of the extrapolation is replaced by more recent data as soon as they are received by the respective receiving communication module wherein the transmission time for the transmission of data from the respective transmitting is taken into account between the respective receiving communication modules in the extrapolation of the received data by the respective receiving communication module.
