Study on the model-based development approach for the electronically controlled system of a high-pressure common-rail diesel engine

Abstract

A model-based V-cycle development approach is investigated in this paper. The control algorithms are modelled, simulated, and optimized using Matlab/Simulink/Stateflow tools. TargetLink is used to translate the control algorithm model made in Matlab/Simulink/Stateflow into embedded production ANSI C codes. Based on the controller of a high-pressure common-rail electronic control system for a diesel engine (ECU) and the hardware-in-the-loop simulation system (HILSS), the codes of control algorithms can be tested and modified again. The results of the investigation show that both Simulink and TargetLink are effective development tools that can guarantee control precision and rationality of control algorithms, and can also help to shorten the development time. The Simulink, TargetLink, ECU, HILSS, and calibration tools form an effective V-cycle development platform for the control algorithm of a high-pressure common-rail electronic control system.
