Abstract: A location device for locating secondary nodes of a vehicle is disclosed. The location device includes a plurality of nodes including a main node and n secondary nodes, with n=2 to N integers, with the whole forming a vehicle network. The vehicle network includes two sub-networks each independently powered by an electrical power supply. each sub-network includes m secondary nodes, with m=1 to M integers. Each secondary node has a unique network identifier indicating whether it is inside or outside the vehicle. The main node is configured for knowing the architecture of the vehicle network, independently activating and deactivating the electrical power supply of each of the two sub-networks, and identifying and locating at least one reference secondary node in at least one of the two sub-networks by means of its unique network identifier among other functions.
