To broaden the range of hardware in loop simulation for electronic controlled unit in application, a study on model simulation of electronic unit pump diesel engine oriented to control is made, the requirements and selection of simulation model oriented to control in electronic unit pump diesel engine are provided, and the model of simplified nonlinearity in diesel engine and electronic unit pump system are established in Matlab/Simulink. Model verification shows that this model can achieve fairly good accuracy. With the calculation time and parameter as evaluation index, different calculation steps and methods affecting the model output are analysed and compared. Real model is applied into hardware-inloop simulation test, its results show that the model can perform real-time ECU hardware-in-loop simula- tion test accurately.
