The goal of this project is to design and test a hydraulic hose and fitting assembly that has the ability to transmit electrical power as well as SAE J1939 CAN bus signal. The intended applications included mobile machinery, automotive, aerospace, manufacturing, and process equipment. The benefits of this approach to power and signal transmission included improved robustness and durability, reduction in parts and faster machine assembly times. Multiple conceptual designs have been generated, including sending current through the existing steel reinforcing layers of the hose, or utilizing a dedicated wire or wires that are embedded in the outer rubber layer or are wrapped around the hose and encased with and additional sheath. Each design will be evaluated according to SAE standards J1939, J343, and J1405, which specify testing procedures for the physical ability of the hose and the requirements for CAN Bus signal protocol.
