1. A method of two-way communication between different nodes arranged at different positions in a vehicle, where information in the form of binary symbols is sent on at least two serial communication busses connecting said nodes, characterised in that the method includes the following steps:

  • separating said nodes into at least two groups where communication between nodes belonging to one group is more or less critical for driving the vehicle with respect to communication between the nodes in another group;

    connecting said different groups of nodes to different communication busses where one end of each bus is connected to a gateway node; and

    transferring the gateway node information within one bus to nodes which are intended for reception of the information and which are connected to another bus.
