| As diesel engine with a high-torque, low fuel consumption, low emissions, and other characteristics of a diesel engine vehicles and construction machinery to resolve the issue of energy the most realistic and most reliable means. But relying on the traditional mechanical control fuel injection system has been unable to meet fuel injection volume, pressure and jet fuel injection is the best time in light of the requirements of operating conditions. In recent years, with computer technology, sensor technology and the rapid development of information technology, electronic fuel injection control is very easy.Since electronic diesel system performs high accuracy as well as rapid respond and is suitable to various algorithms, and has obvious effect on improving of derivability and emissions for diesel engine, electronic control technique has been the main trendy in diesel engine field, Control parameters must be calibrated by the calibration system during the applied development of engine electronic control system in order to have good performance of engine and to guarantee the requirements of emission regulations as well as stable performance.In this thesis, the software development of control unit is researched. The topic-based real-time operating systems and embedded micro-news MMB bus integrated development platform to achieve through the use LABVIEW software electronically controlled engine calibration system without manual control and data acquisition and control system by setting the parameters of calibration, to seek optimal The control parameters, and the optimal control parameters automatically saved to the corresponding ECU memory, shortened the testing process and reduce the labor intensity.Under the LABVIEW circumstance, the calibration platform software for communication between person and system is development. The user-interface is clear, simple and easily manipulative. The use of the calibration platform software cuts down the calibration work by a long way. |
