发动机控制系统Simulink模型中MAP模块的开发

摘要

针对发动机控制系统Simulink模型自动生成的代码不支持MAP标定和烧写的问题,开发了基于S函数的MAP模块.建立使用该MAP模块的发动机模型并生成基于飞思卡尔MPC5634M单片机的控制代码.发动机台架试验结果证明,该MAP模块生成的代码可以实现MAP在线标定和离线烧写功能.%The codes of Simulink model for engine control system could not support the calibration and programming of MAP and MAP module based on S-function was hence developed .Then the corresponding engine model was built and the control codes applied to Freescale MPC5634M was generated .The test results show that the MAP module supports the online calibra-tion and offline programming .
