Abstract: In Matlab/Simulink, basing on the real-time vehicle dynamics simulation software TESIS DYNAware, and by using dSPACE single board DS1103, hardware control signals are connected to the model vedyna_traffic; Selecting “Standard” version of vehicle dynamics model veDYNA in DYNAware, and changing this model by the veDYNA module embedded in Simulink, a virtual experiment system based on DYNAware is established. The simulation control strategy of the adaptive cruise (AC) is analysed, the control model in a “. mdl” mode is integrated into the experiment system. In the main working interface of veDYNA, data of the simulated type vehicle are input through the graphical editor of parameter file and “. m” interface of text editor, and the controllable items of simulation control and the user procedures are set respectively. By veDYNA, simulation traffic module and animation tool module playing their role together, the virtual tests of vehicle AC are carried out in the control of hardware signals, the related parameters are traced and their corresponding curves are compared with the curves which are acquired from the simulated type vehicle having AC function in quality. The results show that this method of AC virtual test research is a good research method.
