Powerline communication controller for communications between a vehicle and a trailer

A system for facilitating powerline communications between a vehicle and a trailer, the system comprising:

• a set of sensors coupled to the trailer and configured to provide signals indicating conditions regarding a set of defined regions of the trailer;
• a housing physically coupled to the trailer;
• a first set of contacts accessible from an exterior of the housing;
• a second set of contacts accessible from the exterior of the housing;
• a set of powerlines coupled between the first set of contacts and the second set of contacts;
• and
• a powerline communication controller contained in the housing, the powerline communication controller electrically coupled to the set of powerlines, communicatively coupled to the set of sensors, and configured to:
• receive a first signal indicating a condition detected by a sensor of the set of sensors in a defined region;
• generate, based on the first signal, a second signal representative of the condition detected;
• and
• introduce the second signal onto a first powerline signal in a first powerline of the set of powerlines.

A method, comprising:

• receiving a first power signal via a first terminal coupled to a first powerline and a second power signal via a second terminal coupled to a second powerline, the first powerline and the second powerline electrically coupling a first electrical system of a vehicle of a vehicle trailer assembly and a second electrical system of a trailer of the vehicle trailer assembly;
• receiving, via a first port of a device interface, a first signal indicating a condition detected by a sensor positioned on the trailer;
• generating, based on the first signal, a second signal representative of the condition detected;
• introducing the second signal onto the first power signal via the first terminal;
• receiving a third signal on the second power signal via the second terminal, the third signal indicating an operation to be performed by a first device positioned on the trailer;
• and
• transmitting, based on the third signal, a fourth signal representative of the operation to the first device via a second port of the device interface.
