A mathematical model based on the principles of the mean-value model of the 16V396TE94 diesel was created to test the functions,performance and accuracy of the electronic control system.From the mathematical model,Tesis and DYNAware were used to build a parametric model simulating the demands of the diesel engine over a wide range of controller inputs.In addition,a powertrain simulation model was also established.A semiphysical simulation platform for the diesel electronic control system was designed and implemented beginning with the simulation model on the dSPACE platform.This was linked with a physical I/O board,an electronic control system and the real actuator.The semi-physical platform was used to test engine startup,speed regulation,and sequential turbocharger working conditions.When compared with test data,the simulation results were 90% correct,and the characteristics followed a consistent trend.The simulation test platform generates high-precision real-time results.It effectively meets electronic control system functions and performance testing requirements.
