Abstract

A device and method for communication among vehicle components operating on different electronic vehicle bus communication protocols is disclosed. The current invention is specifically designed with the capabilities and reliability required for permanent integration of an incompatible device into a vehicle bus network. This allows for installation and permanent integration of incompatible devices onto new and advanced vehicles which are manufactured using the latest electronic vehicle bus communication protocols.
