Feasibility Study on Controller Virtualization and Control Strategy Verification Based on Virtual Platform
The text utilizes the ETAS VECU-BUILDER software to generate a virtual electronic control unit(VECU)for high-pressure common rail pressure control through controller virtualization means,and establishes the controlled object of the high-pressure diesel common rail system model using Simulink software.Utilizing the ETAS COYSM platform,the generated virtual controller VECU and corresponding plant model for the high-pressure diesel common rail system are configured and integrated,thus establishing a closed-loop testing environment for VECU and plant model based on a PC.Based on the constructed virtual testing platform,the validation of high-pressure common rail pressure control strategy is completed.Experimental results demonstrate good tracking performance be-tween actual rail pressure and target rail pressure,indicating that the virtual controller can effectively control the controlled object model in both steady-state and transient conditions.This integrated testing method based on virtual environments not only improves testing efficiency but also helps identify potential issues in the early stages,thereby accelerating the development of control strategies and reducing testing time and development costs associated with actual engine benches.Such forward-looking research not only acceler-ates the application of new technologies but also lavs the foundation for the sustainable development of future vehicles.
