An embodiment is a powerline communications (PLC) apparatus including a communications interface that implements a first communication protocol including of a transceiver that communicates over an electrical power distribution wiring of a vehicle. The first communication protocol includes a powerline communications automotive network (PLCAN) delimiter type (DT) (PLCAN-DT), and a PLCAN variant length field in a frame control comprising payload length, a number of symbols used, a PHY block size, and a number of repetitions used, wherein broadcast addressing is used in the network to transmit messages. 实施例是一种电力线通信(PLC)设备，包括实施了第一通信协议、由在交通工具的电力分布布线之上通信的收发器构成的通信接口。第一通信协议包括电力线通信汽车网络(PLCAN)定界符类型(DT)(PLCAN-DT)，以及在帧控制中的PLCA变量长度字段，包括有效载荷长度、使用的符号数目、PHY组块大小、以及使用的副本数目，其中在网络中使用广播寻址以传输消息。
