摘　　要：变速箱电子控制单元(ECU)的功能越来越复杂,促使开发工程师采用新的开发方法。硬件在环仿真是替代真实环境或设备的典型方法,是现代ECU开发流程中一个比较重要的环节。基于Matlab/Simulink/RTW以及dSPACE的软硬件系统搭建了变速箱ECU硬件在环仿真系统,利用该系统对一个变速箱的电子控制单元进行了简单的测试,验证了换挡规律和换挡逻辑。结果表明:硬件在环是ECU开发的强有力的工具,能够缩短ECU的开发周期,减少开发费用。The more complicated functions of transmission electronic control unit （ECU） impel development engineers to adopt new developing methods. Hardware-in-the-loop simulation is a typical method of replacing real condition or equipment and an important link of modern ECU developing flow. The transmission ECU hardware-in-the-loop simulation system was built based on Matlab/Simulink/RTW and dSPACE to test a certain transmission ECU under many conditions and to validate the shifting rules and logic. The results show that hardware-in-the-loop simulation is a powerful ECU developing tool for shortening ECU developing cycle and reducing developing cost.
