ADAS CONTROL UNIT : Description
INFOID:0000000006227995
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 high 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-28, "CAN COMMUNICATION SYSTEM : CAN Communica-
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 style (two lines twisted) for noise immunity.
