The CAN- FD protocol, CAN Flexible Data (CAN-FD), is a further development of the CAN protocol for automotive technology that meets the increasing bandwidth requirements in automotive applications. The data rates supported by the CAN-FD protocol are above 1 Mbit/s.
The CAN-FD bus has a higher data rate than the CAN bus and is also more flexible. During the development of the CAN-FD protocol, the main focus was on increasing the data throughput. This was achieved by the fact that if only a single node transmits in the CAN bus, the data rate can be increased many times over.
