Information e.g. component stand-by/wake information, exchange system for motor vehicle, has controllers and unit with respective transmitting/receiving units that transmit/receive information by current carrier on electric energy feed line

摘要

The system has controllers (1, 4) and a unit (10) provided with respective transmitting/receiving units (16, 18, 17). The units (16-18) transmit/receive information by current carrier on an electric energy feed line (13). The units (16-18) are implemented uniquely or in combination with information transmission multiplexed network. A controller (7) is connected to a diagnosis bus (14).
