【摘要】：研究与制定了尿素喷射控制单元(DCU)的控制策略,包括尿素喷射控制策略和OBD诊断策略。搭建了SCR系统的半实物仿真平台,自主开发了CAN总线仿真软件,包括CAN初始化设置、CAN网络环境创建、数据发送及接收模块、用于扩展的信息解析模块等。基于CAN总线仿真软件对DCU的尿素喷射控制及OBD功能进行半实物仿真分析,结果表明,本文尿素喷射控制程序及OBD模块程序设计正确。
[Abstract]:The control strategy of urea injection control unit (DCU), including urea injection control strategy and OBD diagnosis strategy, was studied and formulated. The hardware-in-the-loop simulation platform of SCR system is built, and CAN bus simulation software is developed, including CAN initialization setting, can network environment creation, data sending and receiving module, extended information analysis module and so on. Based on CAN bus simulation software, the in-the-loop simulation analysis of urea spray control and OBD function of DCU is carried out. The results show that the design of urea spray control program and OBD module program in this paper is correct.
