CAN FD Protocol
An enhanced version of the Controller Area Network supporting higher data rates.
CAN FD (Flexible Data Rate) improves upon traditional CAN by allowing faster data transmission and larger payloads per message. This enables advanced ECUs to share complex diagnostic and sensor data efficiently. Automotive engineers adopted CAN FD for high-speed communication in powertrain and ADAS systems. It coexists with classic CAN, ensuring backward compatibility. CAN FD is a key step toward more data-intensive architectures like Automotive Ethernet.
