Abstract
A power line communication system includes a master ECU for supplying electric power, a plurality of slave ECUS and a plurality of power-supply lines connecting the slave ECUS to the master ECU respectively. The power-supply lines including at least one first power-supply line on which a control signal is superimposed and at least one second power-supply line on which no control signal is superimposed. The control signal is superimposed on the first power-supply line by the master ECU and also communicated between the master ECU and the slave ECUS connected to the first power-supply line. Impedance per unit length of the first power-supply line is set smaller than impedance per unit length of the second power-supply line.
Claims7
A power line communication system comprising:
- a master station for supplying electric power;
- a plurality of slave stations driven by the electric power;
- and
- a plurality of power-supply lines connecting the slave stations to the master station respectively, the power-supply lines including at least one first power-supply line on which a control signal is superimposed and at least one second power-supply line on which no control signal is superimposed,
- wherein the control signal is superimposed on the first power-supply line by the master station and also communicated between the master station and at least one slave station connected to the first power-supply line, and
- impedance per unit length of the first power-supply line is set smaller than impedance per unit length of the second power-supply line.
