Commander

The Figure 19 shows the block diagram of the commander as referred in the Figure 18. The protocol commander

uses a standard CAN FD protocol controller that may be already implemented in the automotive microcontroller in

hardware or software. An additional CAN FD protocol extension software controls this protocol controller to make

it act as CAN FD light compatible commander and implements the commander side of the CAN FD light

compatible protocol.

To access the physical interface of the CAN FD network a standard CAN FD transceiver is used.
