SYSTEM / Control System GENERAL 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 The controllers are mutually connected through CAN, and each controller uploads the analog signals de- tected by the sensors and switches as well as the analog output signals to the solenoid valves on CAN by converting them into the digital signals. As the signals are processed into the digital signals, a large amount of signals detected by each controller can be transmitted through few wires in a shirt time.
MC, ECM and the monitor unit display indications on the monitors and make various controls of the vehicle body by using the analog signals received by each controller as well as the digital signals detected on CAN. ICF stores machine history, receives the digital signals for various adjustments from Dr. ZX, transmits them to CAN, and transmits the vehicle body information (digital signal) received by each controller to Dr. ZX. A GPS-provision (optional) vehicle makes location arithmetic operation, utilising the signals received by artificial satellites and transmits body information to the e-service host computer through the artificial satellites.
