Multiplex Communication System - CAN Bus

System Outline

CAN has two lines as a pair which make communication with operating voltage. CAN has excellent data speed and error detecting capacity. It consists of vehicle control systems such as data link connector 3, air suspension ECU, steering sensor, skid control ECU with actuator, engine control module, yaw rate sensor, distance control ECU, television camera ECU, seat belt control ECU and gateway ECU. Gateway ECU has communication circuit to correspond different types of communication data. Different types of communication data can be shared among communication parts after it go through gateway ECU.
