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 communicate data but selectively reads required data only.
