Vehicular electrical system that provides power and communications to controllable vehicular devices includes an electrical bus having elongate wires, an electrical source connected to the bus, and control units each attached to one or more of the devices. Couplers couple transceivers to the bus to enable messages generated by the transceiver to be provided to the bus and messages on the bus to beretrieved by the transceiver using an identification protocol. Each coupler includes an annular magnetic unit arranged around the wires, and a coil wound around part of the magnetic unit and connected to a respective transceiver. Power and communications are provided to the devices from a power source and communications source coupled to the bus through the bus, the transceivers and the control units coupled to the transceivers to cause a change in operation of the devices based on messages on the bus.
向可控制的车辆设备提供电力和通信的车辆电气系统包括具有细长电线的电气总线,连接到总线的电源以及分别附接到一个或多个设备的控制单元。耦合器将收发器耦合到总线,以使收发器使用标识协议将由收发器生成的信息提供给总线,并使总线上的信息被收发器检索。每个耦合器包括围绕导线布置的环形磁性单元,以及缠绕在磁性单元的一部分周围并连接到相应收发器的线圈。电源和通信从通过总线耦合到总线的电源和通信源,收发器和耦合到收发器的控制单元提供给设备,以基于总线上的信息引起设备操作的改变。
