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)

For locations of each component on vehicle, refer to Component Location Index

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 pided 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-
