Information Bus: Description and Operation
Multiplex Communication System - CAN
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 gateway ECU, data link connector 3, 4WD control ECU, airbag sensor assembly center, distance control ECU, engine
control module, power steering ECU, seat belt control ECU, skid control ECU (w/ vehicle dynamics integrated management), skid control ECU with
actuator (w/o vehicle dynamics integrated management), steering sensor and yaw rate sensor. Gateway ECU has communication circuit to correspond
with different types of communication data. Different types of communication data can be shared among communication parts after it goes through
gateway ECU.
