PURPOSE: A network system of a car using a CAN(Controller Area Network) protocol is provided to allow each ECU(Electrical Control Unit) to systematically communicate through the CAN protocol so that efficient network control is possible, and to use a CAN bus so that the number of wires for electrically connecting each device is largely reduced. CONSTITUTION: A BCM(Body Control Module) block(31) communicates data related to a car body with each ECU block through a CAN bus(100). A drive door module block(33) communicates mirror operation signals, fold operation signals, Window operation signals, seat and handle tilt signals, memory-related signals, etc. with each ECU block through the CAN bus(100). An assist door module block(35) communicates data on whether an assistant seat is opened or closed, etc. with each ECU block through the CAN bus(100). A power seat ECU block(37) communicates data related to car transmission and data related to each motor for controlling a seat with each ECU block through the CAN bus(100). And a tilt ECU block(39) communicates data related to handle tilt control, telescope control, inside mirror control, etc. with each ECU block through the CAN bus(100).
