Abstract
A power line communication device for a vehicle is provided with an internal electronic control unit connected to a connection point on a power line, which communicates with an external electronic control unit by a communication signal superimposed on a supply voltage applied to the power line, and an impedance element inserted between the connection point and an external load. The impedance element suppresses attenuation of the communication signal.
