基于硬件在环仿真的变速箱电子控制-基于硬件在环仿真的变速箱电子控制.rar 变速箱电子控制单元 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。 Abstract: The more complicated functions of transmission electronic control unit impel develop2 ment engineers to adopt new developing methods. Hardware2in2the2loop simulation is a typical method of replacing real condition or equipment and an important link of modern ECU developing flow. The t ransmission ECU hardware2in2the2loop simulation system was built based on Matlab/ Simulink/ RTW and dSPACE to test a certain t ransmission ECU under many conditions and to validate the shifting rules and logic. The result s show that hardware2in2the2loop simulation is a powerful ECU developing tool for shortening ECU developing cycle and reducing developing cost .
