摘　　要：为提高电子换挡器的换挡性能,基于英飞凌TC234微处理器设计了电子换挡控制器的硬件平台,利用AUTOSAR工具建立了电子换挡控制器,包含基础软件、运行时环境和应用层软件的层次化软件架构,并在MATLAB/Simulink中完成应用层核心控制算法的图形化开发和代码自动生成,最后在变速器总成上对系统功能进行了试验验证。结果表明,控制系统的硬件与软件设计较好地实现了系统目标,挡位角度自学习结果偏差远小于0.5°,换挡电机的位置控制偏差小于0.35°,挡位角度自学习算法与换挡电机位置控制算法均具有良好的一致性和控制精度,系统性能满足电子换挡器的使用要求。In order to improve shift performance of electronic gear shifter,the hardware platform of the electronic shift controller is designed based on Infineon TC234 MCU,and the hierarchical software architecture of the electronic shift controller which includes basic software,runtime environment and application layer is established by using AUTOSAR tool.In addition,the graphical development of the core control algorithm of the application layer and the automatic generation of code are completed in MATLAB/Simulink.Finally,the function of the system is tested and verified on the transmission assembly.The test results show that the hardware and software design of the control system achieve the system design objectives well,the deviation of self-learning result of gear angle is far less than 0.5°,and the position control deviation of shift motor is less than 0.35°,the test self-learning algorithm of gear angle and the control algorithm of motor position have good consistency and control precision,and the system performance can meet the requirements of electronic gear shifter.
