CAN COMMUNICATION
CAN (Controller Area Network) is a serial communication
line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control units , and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN-H, CAN-L) allowing a hi gh rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads the required data only.
CAN communication signal chart. Refer to LAN-32, "CAN COMMUNICATION SYSTEM : CAN Communica-
tion Signal Chart".
ITS COMMUNICATION
• ITS communication is a multiplex communication system . This enables the system to transmit and receive
large quantities of data at high speed by connecting control units with 2 communication lines.
• ITS communication lines adopt twisted-pair line st yle (two lines twisted) for noise immunity.
