Hardware-In-the-Loop Simulation of electronic control unit used on Automated Mechanical Transmission

The development of Automated Mechanical Transmission (AMT) can lightening drivers´ labor intensity, improving vehicle power and economic performance. Simulation technology can accomplish tests rapidly, shorten developing time and save study expense. A Hardware In the Loop Simulation (HILS) system can be developed to debug, examine and evaluate the performance of Automated Mechanical Transmission Electronic Control (AMTECU). The system consists of data acquisition card, computer, AMT electronic control unit, and engine and chassis simulation model. And Engine´s partial velocity characteristics model and universal characteristics model were established. The optimum dynamic performance and economic performance shift law was analyzed. An optimal work model of AMT was discussed. Dynamic and economic parameters are deduced. A simulation system was developed.
