摘　　要：针对柴油机排放颗粒物(PM)和NOx控制,将柴油氧化催化器(DOC)、柴油颗粒捕集器(DPF)以及选择性催化还原(SCR)系统组合形成集成后处理系统方案,基于汽车开放系统架构(AUTOSAR)进行柴油机DPF和SCR集成控制系统软件分层设计。首先研究了DPF和SCR集成控制系统的应用层策略,然后进行应用层模型的搭建以及底层驱动模块的设计,最后进行应用层和底层代码自动生成。以恩智浦公司MC9S12XEP100单片机为控制平台,对柴油机后处理控制系统进行了试验测试,结果表明,该控制软件可实现基本控制功能以及对PM和NOx的控制,符合国六排放标准。For the control of diesel Particulate Matter(PM)and NOx,the DOC,DPF,and SCR system are combined to form an integrated aftertreatment system solution.The software layer of DPF and SCR integrated control system for diesel engine is designed based on AUTOSAR.Firstly,the application layer strategy of DPF and SCR integrated control system is studied.Then the application layer model is built and the underlying driver module is designed.Finally,the application layer and the underlying code are automatically generated.Then,with the MC9S12XEP100 MCU of NXP as the control platform,relevant experimental tests are carried out on the diesel engine aftertreatment control system.The results show that the aftertreatment integrated control software can realize the basic control functions,the control of PM and NOx,and meet the emission standards of the national standards(China 6).
