Communication Systems (F-CAN) Description
F-CAN (High-speed CAN) (without CAN gateway)
The network between the powertrain and control units for chassis system is called F-CAN and it employs high speed CAN with communication rate at 500 kbps.
F-CAN (High-speed CAN), CAN Gateway (with CAN gateway)

The network between the powertrain and control unit for chassis system is called F-CAN and it employs high speed CAN with communication rate at 500 kbps. In order to increase the number of the control units connected to F-CAN bus, it is divided into two F-CAN buses, and the CAN gateway is adapted to connect between each F-CAN bus (F-CAN A: conventional F-CAN structure, F-CAN B: F-CAN structure using the CAN gateway).
Typical CAN Bus Communication Operation
The F-CAN detects the differential voltage generated between two communication wires (CAN_H and CAN_L) and uses it as a signal level. This is a digital signal that indicates "1" when equal voltage is found and "0" when unequal voltage is found.
