U1010 CONTROL UNIT (CAN)
Description
INFOID:0000000009175653
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 unit, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with two communication lines (CAN-H and CAN-L) allowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.
