Improving PLC Performance With an Integral Filtering Module

The introduction of PLC4Trucks to “light the light” introduces new complexities to the wiring system of the tractor and trailer. To electronic equipment not designed to read the PLC4Trucks signal, it appears as undesirable high-frequency noise on the input power line. In addition to the interference generated by PLC4Trucks for non-PLC electronics, these same non-PLC electronics can generate noise, which can interfere with the PLC4Trucks signal. This paper outlines the development and implementation of a filter module that reduces the both of these effects while improving the signal strength at the Tractor ABS ECU.
