Study Of Electronic Control Of Diesel Based On Rhapsody

The aim of the research and production of the diesel is to increasing the power,economic of the diesel,decreasing the emission and noise. The demand for better vehicle performance, coupled with the increased regulatory on emission level and fuel economy have caused increasing functionality and complexity of engine electronic control units, which results in a more difficult, more costly and time_consumption development work. In this paper, the studying of programme based on the model has been developed to improve the efficiency of developing electronic control of diesel.A standard personal computer is used as host computer to serve as the soft design; the environment of the application design is the Rhapsody, which is base on the UML; Using the MPC564EVB as the target board, A 32 bit microprocesser is the PowerPc MPC563 of MOTOROLA, and using OSEKTurbo, which is a real-time operation system(RTOS) and special for the electronic control of the automobile. In this paper, in the development environment of Rhapsody, analyzing the function of the electronic control uint and designing a model of the diesel electronic control unit, after do it ,Rhapsody can product code by itself; RTOS is configured in the OSEKBuilder. In Rhapsody, model is the core and base of the designing programme.All the application is compiled and linked in the CodeWarrior IDE and product executable code that is suit to the hardware desktop. In the CodeWarrior IDE, there is an Debugger, which can download the executable code to the target hardware then code can be executed and tested on the board.
