Following the offline optimization, control rules are extracted from the DP data through outlier detection and graphical methods. This step is crucial for transitioning from complex offline optimization to a practical, real-time implementable strategy, ensuring both efficiency and adaptability for continuous operation.
Adaptive Control for Real-world Scenarios
For real-time adaptability, the proposed EMS integrates a Relevance Vector Machine (RVM) for driving cycle recognition and an Improved Particle Swarm Optimization (IPSO) algorithm for online parameter optimization. This allows the system to dynamically adjust control parameters based on identified driving conditions, achieving variable-parameter optimal control in a continuous operational environment.
| Metric | DP Control (L/100km) | Logic Threshold (L/100km) | Proposed Control (L/100km) | Improvement vs. Logic Threshold (%) |
|---|---|---|---|---|
| Urban Cycle Fuel Economy | 16.97 | 19.45 | 17.51 | 14.6% |
| Mixed Cycle Fuel Economy | 17.68 | 20.12 | 18.20 | 13.8% |
| Real-world Cycle Fuel Economy | 16.45 | 18.95 | 17.02 | 15.2% |
The comparison clearly demonstrates that the proposed adaptive control algorithm consistently delivers significant fuel economy improvements over traditional logic threshold control across various driving cycles. This highlights its effectiveness in balancing global optimality with real-time, adaptive performance, making it highly suitable for enterprise fleet management.
Simulation & HIL Test Outcomes
The proposed adaptive EMS was rigorously validated through both offline simulations and Hardware-in-the-Loop (HIL) tests. These validation steps confirm the algorithm's real-time performance and its ability to achieve near-optimal energy-saving effects under practical operating conditions.
Hardware-in-the-Loop Validation Results
The HIL test platform confirmed the real-time performance and fuel efficiency of the proposed adaptive EMS. Comparison between offline simulation and HIL test under urban cycle shows negligible difference:
- Offline Simulation: 17.35 L/100km
- HIL Test: 17.40 L/100km
- Initial/Final SOC: 70%/70.25%
This demonstrates the algorithm's robustness and capability to maintain SOC balance in real-world conditions, validating its readiness for deployment in complex operational environments.
