CAN Communication
For California
CAN COMMUNICATION
System Description
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high
data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, 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 line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
