利用标准的V型开发流程和相应开发工具,设计开发了基于转矩的柴油机高压共轨系统控制算法,重点开发了全新的以转矩为控制目标的算法架构。首先在Matlab/Simulink软件环境下进行了详细的算法设计,完成了算法快速原型验证、代码自动生成、系统集成、发动机与整车标定试验等工作,并建立了软件数据标定流程。实车测试表明:基于转矩的柴油机高压共轨系统控制算法有利于满足发动机和整车的匹配要求,缩短标定时间,同时为整车网络化集成控制打下基础。

This paper developed torque-based control algorithm for high pressure common rail system of diesel engine using V-cycle development mode,with its emphasis on the developing of torque-oriented algorithm architecture.The detailed control algorithms were first designed in Matlab/Simulink,then through rapid control prototyping validation,code generation,system integration,and engine and vehicle calibration.Vehicle test results indicate that torque-based control algorithms make the matching and calibration between engine and vehicle easier,also make it feasible for vehicle network control.
