【Abstract】 An ASR Co-simulation model for JETTA GTX is presented in this article. ADAMS/CAR is used to build ASR mechanical dynamics model and MATLAB/SIMULINK is used to build the control model of ASR. We consider about the most important fa ctor that may have impact on the process of ASR, and use semi empirical model to describ e some important subsystem that is difficult to describe with formula. The model ’s rationality is validated by the co-simulation for μ-split road test, and the co-simulation model can simulate the vehicle’s dynamic response with the contro l of ASR in various operating conditions. As a result, it is an exacter and fe asible model for speeding up the development of the ASR algorithm.更多还原
