双离合器自动变速器硬件在环仿真试验研究

TCU hardware-in-loop simulation system based on MATLAB/Simulink/dSPACE was developed, and the system model was divided into six submodels which include system dynamics model, TCU model, DCT model, driver model, engine and EMS model. The structure and principle of each submodel was introduced in detail. Based on this, the TCU hardware-in-loop simulation test platform was set up by embedding the real TCU hardware into the simulation circuit to instead of the TCU model in the pure simulation model. The test principle and method of the starting and shifting of DCT vehicle were introduced and tested on the TCU hardware-in-loop simulation platform. The results show that DCT control effect is favourable, TCU hardware-in-loop simulation system has a clear structure, distinct gradation, strong portability and functional division of each submodel is explicit. It can complete the test of controller under the experimental conditions, and also the cost of development was reduced, the cycle of development was shorten.
