摘　　要：针对目前高压共轨柴油机电控系统开发周期较长以及开发成本较高的问题,通过研究基于模型的软件开发流程,在Matlab/Simulink环境下建立了高压共轨柴油机主喷油量控制算法模型,其中包括烟度限值控制模型、启动油量控制模型、怠速油量控制模型、怠速PID控制模型以及油量脉宽转换模型;对控制算法模型的关键MAP图进行了标定以验证该控制算法模型的有效性,并在使用INCA标定软件建立监控和标定的发动机试验台架上进行了一系列试验。试验结果表明,发动机启动过程迅速,且正常工况下转速稳定,并能根据环境情况和发动机的当前需求自动调节目标油量;该控制算法能够较好地满足发动机起动、怠速以及正常工况的控制需求。Aiming at the problem that the development period of the electronic control system of high pressure common rail diesel engine is longer and the development cost is higher, through the research on the model based software development process, the model of the main fuel injection quantity control of high pressure common rail diesel engine was established under the Matlab/Simulink environment. The control al- gorithm model includes the model of the limit value of smoke, starting the oil quantity control model, the model of the idle oil quantity control, the PID control model and the pulse width conversion model. The key MAP diagram of the control algorithm model was calibrated to verify the validity of the proposed control algorithm. A series of experiments were carried out on the engine test bench using INCA calibration software. The results indicate that, the engine starts up quickly and steadily, and can adjust the target oil automatically according to the envi- ronment and the current requirement of the engine. The algorithm can meet the requirement of engine starting, idle and normal operation.
