摘要
本文研究基于MPC5534微控制器的柴油机高压喷射ECU的多次喷射控制,按照AUTOSAR标准构建ECU系统框架,根据功能将ECU划分为由传感器和信号处理硬件构成的输入模块、硬件和软件的结合控制策略层和由驱动硬件组成的输出模块。在MATLAB平台上进行来模型描述和参数影响分析,建立了五次喷射控制策略。实验结果表明,喷射控制精度满足实时性和可靠性要求。
Studies of high pressure common rail diesel engine ECU was conducted and the whole system was divided into input module,control strategy and output modules according to functions.The input module was made up of sensors and hardware for signal processing,control strategy was the combinations of hardware and software,and the output module is actuators.The model was described and analyzed on MATLAB for 5 injections control.The results showed that the precision of injection control and the real time performance can meet the requirement of engine.
