TL;DR: In this article, the authors describe a vehicle implementing a processing module for receiving data from a high-speed CAN bus and sending data to a low speed CAN bus, which is designed to be replaceable and/or upgradable without affecting other components during the life cycle of the vehicle.

Abstract: The present disclosure describes a vehicle implementing a processing module for receiving data from a high-speed CAN bus and sending data to a low-speed CAN bus. The processing module shunts into the data from the high-speed CAN bus without affecting the self-contained data flow of the high-speed CAN bus. The processing module analyzes the received data and generates data (by forwarding or other means) to be sent to a low-speed CAN bus according to the received data. The processing module is designed to be replaceable and/or upgradable without affecting other components during the life-cycle of the vehicle. The processing module may further contain expansion modules that perform tasks in response to the received data.
