• There are four controllers as shown below with MC – Main Controller – installed at their center.
  · MC: Main Controller
  · ICF: Information Controller
  · ECM: Engine Control Module
  · Monitor Unit
• Controllers are mutually connected through CAN, and each controller uploads analog signals detected by sensors and switches as well as analog output signals to solenoid valves on the CAN by converting them into digital ones.
• As the signals are processed into the digital ones, a large amount of signals detected at each controller can be transmitted through few wires in a short time.
• MC, ECM, and monitor unit display indications on monitors and make various controls of the vehicle body by using analog signals received by each controller as well as digital signals detected on the CAN.
• ICF stores machine history, receives digital signals for various adjustments from Dr-ZX, transmits them to the CAN, and transmits the vehicle body signal (digital signal) received by each controller to Dr-ZX. A GPS-provision (optional) vehicle makes location arithmetic operation, utilising signals received by artificial sattelites, and transmits body information to the e-service host computer through artificial satellites.
