- Key functions & working principle
| Working Principle | 1. Data Acquisition: The MCU receives analog/digital signals from onboard sensors (pressure, temperature, position, engine speed) via I/O ports and CAN bus. |
| 2. Logic Processing: Using pre-programmed control algorithms (Hyundai IPC software), it processes sensor data to calculate optimal engine load, hydraulic pressure, and actuator positions. |
| 3. Command Output: Sends calibrated signals (digital/PWM) to hydraulic solenoid valves, fuel injectors, and cooling fans to adjust system operation (e.g., increase hydraulic pressure for heavy digging, reduce engine RPM for idle). |
| 4. Fault Monitoring: Continuously checks for sensor/actuator faults (e.g., open circuits, short circuits); stores error codes in memory and triggers dashboard warnings for critical faults (e.g., low hydraulic pressure). |
| 5. Diagnostics/Updates: Communicates with Hyundai Hi-MATE tool via CAN/Ethernet for error code reading, performance data logging, and firmware updates to optimize control logic. |
| Core Functions | 1. Engine-Hydraulic Coordination: Balances engine power output with hydraulic system demand – improves fuel efficiency by 8–12% vs. non-IPC systems |
| 2. Real-Time System Control: Adjusts hydraulic valve opening/closing speed and fuel injection timing for smooth, responsive equipment operation |
| 3. Fault Detection & Reporting: Identifies sensor/actuator faults, stores error codes, and alerts operators via dashboard indicators – reduces unplanned downtime |
| 4. Performance Optimization: Adapts control logic to operating conditions (e.g., light load vs. heavy load) – maximizes productivity while minimizing component wear |
| 5. Telematics Integration: Transmits operational data (fuel usage, fault codes) to Hyundai’s remote monitoring system (Hi-Remote) – enables predictive maintenance |
