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 independently). 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 required data only.
