Patent ID: 7869918

Claim:
A method of identification of the nodes (N 1 , N 2 , N 3 , . . . , N n ) of a computer network in an air conditioning installation of a motor vehicle comprising a plurality of peripherals ( 10 1 , 10 2 , 10 3 , . . . , 10 n ) connected to respective nodes of a computer network connected to a central control unit ( 12 ), said method comprising the steps 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 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 signature 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, wherein after input of the electric signatures at the level of the peripherals, a data string is transmitted by the central control unit ( 12 ) over the computer network ( 14 ), the data string comprising relative position data of peripherals each associated with a respective address data item, and each peripheral extracts from the data string transmitted the address data item associated with the relative position data item corresponding to that generated at the level of this peripheral.
