Networking Heavy-Duty Vehicles Based on SAE J1939
ثبت نشده
چکیده
In networking ECUs in heavy-duty vehicles, it is the J1939 protocol that plays a key role. J1939 networks are based on the CAN bus (high-speed CAN per ISO11898); they are primarily used in powertrain and chassis components. The protocol creates a uniform basis for communication between electronic control units, and it supports the plug-and-play principle. Special J1939 tools and software components spare developers from needing to train in the details of the J1939 protocol, and they improve the quality of the development process.
