SAE J2284-4 CANFD規(guī)范 The objective of SAE J2284-4 is to define a level of standardization in the implementation of a 500 kbps arbitration bus with CAN FD Data at 2 Mbps vehicle communication network using the Controller Area Network (CAN) protocol. The goal is to achieve a standard Electronic Control Unit (ECU) Physical Layer, Data Link Layer, and Media Design Criteria which will allow ECU and tool manufacturers to satisfy the needs of multiple end users with minimum modification to a basic design. Likewise, end users will benefit in lower ECU cost achieved from the high volumes of the basic design.
