System interconnection logic
Implement attitude sensors, pressure/displacement sensors, operating handles and load monitoring signals are connected to the IMCU, completing operating-condition recognition, closed-loop computation and action correction; it outputs precise control commands to drive the hydraulic valve groups and implement actuators, and synchronously cooperates in real time over the bus with the VCU, HCU, TCU and IO unit, matching vehicle powertrain and speed, avoiding conflicts among implement, powertrain and speed conditions, and achieving independent and precise control of operating implements together with a coordinated closed loop of complete-machine conditions.
1. Precise closed-loop control of implement attitude and operation.
Supports multi-dimensional closed-loop management of implement tilt angle, displacement and pressure, accurately locking tillage depth, excavation angle and leveling height, automatically correcting operating deviation caused by bumping and terrain undulation, and completely solving the problems of uneven tillage depth, poor leveling precision of engineering equipment and low operating repeatability.
2. Variable-load adaptive operation strategy.
Real-time recognizes implement operating resistance and sudden load changes, and dynamically adjusts hydraulic flow, pressure and action speed — speeding up and increasing efficiency under light load and slowing down and stabilizing force under heavy load — adapting to hard soil, gravel, mud and rugged terrain, and eliminating implement stalling, action jamming and operation failure.
3. Smooth buffering control of implement actions.
Equipped with action slope filtering and impact buffering algorithms, it optimizes the timing of implement start/stop, lifting/lowering and reversing actions, suppresses hydraulic shock and mechanical jitter, greatly reducing implement structural fatigue, valve group wear and pipeline impact, and improving operating smoothness and control feel.
4. Multi-level implement overload protection and anti-jamming.
Features load-overlimit judgment, pressure peak limiting, stall reverse force relief and automatic back-off logic, providing automatic protection for scenarios such as implement burial jamming, sudden load surge and foreign-object blockage, avoiding implement structural deformation, hydraulic component damage and motor overload burnout.
5. Field-condition adaptive parameter calibration.
Adapted to the complex field environments of high/low temperature, humidity and dust, it supports self-learning of implement operating parameters and wear adaptive compensation, offsetting control deviations caused by oil temperature changes, valve body aging and sensor drift, and ensuring consistent long-term operating precision of equipment.
6. Vehicle-condition cooperative matching management.
Can link vehicle speed, powertrain output and gear shift status to realize the cooperative logic of “precision operation at low speed, transit at high speed”: automatically limiting vehicle speed and boosting implement power during operation, and resetting implement attitude during transit, eliminating conflicts between operating and driving conditions.
7. Unmanned implement autonomous operation adaptation.
Adapts to the automated operation needs of unmanned agricultural machinery and unmanned engineering equipment, supports preset operation processes, automatic attitude adjustment and fault shutdown protection, and can link with the intelligent driving domain controller to achieve unmanned precision tillage, leveling and excavation operations.
1. Operating precision greatly improved, construction quality standardized.
Abandoning the traditional extensive manual operation logic, it achieves standardized implement operation through precise closed-loop control, eliminating manual operation errors; tillage, leveling and excavation operations are uniform and regular, and equipment operating consistency and finished-product quality are significantly improved.
2. Dedicated implement control algorithms under independent control.
The full set of strategies for implement closed-loop control, load adaptation, anti-jamming and condition coordination is independently developed, with no overseas technology authorization binding, and dedicated control logic can be quickly customized for different implements such as excavation, loading, harvesting and rotary tillage.
3. Greatly reducing implement failure rate and O&M costs.
Through flexible operation, overload protection and impact buffering strategies, it effectively reduces wear and damage to implement structures, hydraulic valve bodies and transmission components, lowering equipment failure downtime, extending implement service life and reducing after-sales maintenance investment.
4. Rapid iteration adaptation for all categories of off-highway equipment.
The modular software and hardware architecture supports upfront MIL/SIL/HIL simulation verification, and most implement operating parameters can be calibrated and iterated virtually, greatly shortening the R&D and adaptation cycles of new equipment and new implements.
5. Industrial-grade high reliability for high-intensity field operation.
The hardware meets industrial-grade standards for wide temperature range, dust protection, shock resistance and electromagnetic interference resistance, adapts to the harsh conditions of construction sites, fields and mining areas, and supports long-term continuous high-intensity implement operation with stable and reliable operation.
6. Complying with off-highway equipment mass-production compliance standards.
Has completed the full set of verification tests for high/low temperature durability, vibration and shock, EMC and extreme load protection, directly meeting the needs of off-highway implement equipment for inspection, type testing and mass-production support.
