1. Method of identification of the nodes (N1, N2, N3, . . . , Nn) of a computer network in an air conditioning installation of a motor vehicle comprising a plurality of peripherals (101, 102, 103, . . . , 10n) connected to respective nodes of a computer network connected to a central control unit (12), characterised in that it comprises the steps which consist of:

  • inputting at the level of each peripheral an electric signature on a common conductor (14;

    16;

    18), detecting at the level of each peripheral an electric signal depending upon the electric signatures of the peripherals situated upstream on the common conductor (14;

    16;

    18), generating at the level of each peripheral a data item representing a relative position of the peripheral on the basis of the electric signal detected at the level of this peripheral, and identifying each node of the network on the basis of the relative position data collected by the peripheral connected to this node;
