Abstract
Multiplex communication in a vehicle is provided by a multiplex bus using complementary signals, such as a CAN bus. Bus redundancy for providing a backup communication channel in the event of a fault on the primary multiplex bus is achieved using power line communications (e.g., sending data over the already available DC power line). The need for additional circuitry is minimized by preserving the same message protocols (e.g., framing), because only signal conversion, filtering, and switching functions are required in order to divert messages via the power line.
