【Abstract】In this paper,a physical model of AMT was constructed based on dSPACE real-time simulation system,including engine model,clutch model,transmission model,vehicle dynamics model,etc. in order to obtain more close to the real vehicle vehicle dynamics simulation model. Based on this hardware in the loop system,the main control functions of TCU are verified,which can meet the needs of software testing. Through this system,problems are found in advance,and the cost of controller development is reduced.
