Faced with the need to reduce development time and cost, the hardware-in-the-loop simulation increasingly proves to be an efficient tool in the development of automotive engine control system. In this article, the rapid prototyping technology is used to develop a hardware-in-the-loop simulation system for the diesel engine electronic control unit development.The hardware-in-the-loop simulation presented in this paper is based on Linux RTAI system, an open source hard real-time extension of the Linux Operating System, at low costs and within industrial standards. It exploits standard x86-based computing platforms provided with real-time Linux software in combination with generic computer-aided design software (Matlab/Simulink). One of its main characteristics is that it can automatically generate the real-time simulation code for many target processors, which runs under Linux RTAI operating system. The computer-aided design has benefits in reducing development period and optimizing the control parameters. It also enhances the adoption for software and relative hardware in various environments.The core of the real-time simulation system is the dynamic models, it affect the workability and the reliability of the whole system. In this paper, a combination of mean value model and “filling and emptying” model that can perform real-time simulation of turbocharged diesel engine is adopted. Finally, an application of a turbocharged diesel engine was implemented to validating the effect of the hardware-in-the- loop simulation system.
