Bus system i.e. local interconnect network bus, operating method for motor vehicle, involves performing communication between master and slave nodes by conductor and ground and supplying slave node with energy by conductor at separate time

摘要

The method involves performing communication between a master node i.e. local interconnect network-master, and a slave node i.e. local interconnect network-slave, by a conductor (BUS) and a ground (GND), and supplying the slave node with energy by the conductor at separate time. A transmission/receiving unit (TCslave) and a communication controller (CCslave) of the slave node are supplied with energy from a local storage (C13) in an operating case of the communication. Messages and conditions defined in a bus system are processed during an operating case of the energy supply.
