A developing method of transmission electronic control unit based on hardware-in-the-loop simulation

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.
