A hardware-in-the-loop simulating platform is developed to avoid designing de fects caused by the complicated logical structure and multiple-functional build up of the electronic control unit(ECU)in modern diesel engines, and to diminis h potential damages on components or human exposure to dangers in R&D endeavor. This platform consists of a computer installed with software Matlab/Simulink/RTW and dSPACE/ControlDesk; a diesel engine ECU, and a dSPACE autobox which runs a real-time diesel engine model. A typical model of diesel engine with turbocharg er and intercooler is presented. Based on this model our research is carried out with a real ECU to test its software control strategies. Results show that by u sing the diesel engine model downloaded inside, the hardware-in-the-loop plat form can simulate diesel engine’s working conditions and generate all kinds of s ensor signals which ECU needs on a real-time basis. So the ECU control strategi es can be validated and relevant parameters roughly calibrated.
