    • The invention relates to a vehicle network (1) comprising at least two control units (2,3), which exchange data messages (7) with one another, the data content (DI) contained in said data message (7) being pre-defined in such a way that a control unit receiving a data message can deduce its significance by means of the position of the data content (DI) in the data message (7). According to the invention, at least one transmitting control unit transmits at least in one data message (7) a vehicle network version that has been assigned to said unit in the form of data content (DI) and the receiving control unit registers the transmitted vehicle network version and assigns the significance that has already been assigned to the vehicle network version of the transmitting control unit to the remaining data content (DI) of the data message (7) or messages.
    • 本发明涉及包括彼此交换数据消息(7)的至少两个控制单元(2,3)的车辆网络(1),包含在所述数据消息(7)中的数据内容(DI) 以这样的方式定义,即接收数据消息的控制单元可以通过数据消息(7)中的数据内容(DI)的位置推断其重要性。 根据本发明,至少一个发送控制单元至少在一个数据消息(7)中发送已经以数据内容(DI)的形式分配给所述单元的车辆网络版本,并且接收控制单元登记发送的车辆 网络版本,并将已经分配给发送控制单元的车辆网络版本的重要性分配给数据消息(7)或消息的剩余数据内容(DI)。
