摘要
为检验所设计的SCR系统添蓝计量泵控制策略是否正确和CAN总线通讯是否正常,建立了基于CANoe和Simulink的联合仿真模型。利用联合仿真模型进行了包含计量泵节点的仿真分析和OBD诊断仿真分析,验证了计量泵控制策略和CAN总线通讯的正确性,并根据仿真结果完善了计量泵驱动程序和CAN通讯程序的设计。
In order to test and verify the control strategy and CAN communication of SCR Adblue dosing pump, we establish a co-simulation model based on CANoe and Simulink, in which, the simulation analysis of the dosing pump nude and OBD is carried out, and the correctness of the control strategies and CAN communication of the dosing pump is verified. In addition, the design of the drive program and CAN communication program is improved in accordance with the simulation results.
