Towards power line communication in vehicle

This paper is a review of studies dealing with Power Line Communication (PLC) in vehicle. The electronic control units (ECUs) that replace mechanical or hydraulic systems require specific buses in order to exchange information between sensors and actuators. Different networks as LIN, CAN, Flexray have been proposed, from low up to high data rate. Considering these networks, we can observe that each solution uses its specific wires and communication system. The growth of the complexity leads to the necessity to commit to a limited set of networks which answers to these multiple applications. An attractive solution to reduce the wires is the power line communication (PLC) using the power lines (12/42V) to transmit both the power and the messages without functional barriers domain. The channel characterizations of the PLC lines, the impact of the noise, and the resulting system parameters are presented. Taking into account the PLC channels, optimizations of the system parameters are carried out especially the CP length and the bandwidth, Numerical results show obtained significant improvements.
