1. A method for transmitting a data element between a first control unit of a vehicle and a second control unit of the vehicle, wherein the first control unit and the second control unit are coupled to one another via at least two communication channels, comprising:
determining using the first control unit a communication channel indicator of a first communication channel of the at least two communication channels, wherein the communication channel indicator is representative of available transmission resources of the first communication channel;
receiving using the first control unit a data element from a data source;
ascertaining a priority of the data element depending on a vehicle application associated with the data element; and
determining using the first control unit a communication channel indicator of a second communication channel of the at least two communication channels, wherein the communication channel indicator of the second communication channel is representative of available transmission resources of the second communication channel; and
if the communication channel indicator of the first communication channel and the communication channel indicator of the second communication channel indicate that the available transmission resources of the first communication channel and the available transmission resources of the second communication channel are not sufficient for the transmission of the data element and the priority of the data element is less than a predefined priority threshold value, then storing the data element in a temporary memory of the first control unit for a predefined time interval.
