Vehicle track coupling dynamics is a new theory developed on the basis of the conventional vehicle dynamics and track dynamics. In the past decade, great progress was made in the theoretical study and a theory system was formed. In the paper, the research history background of the vehicle track coupling dynamics is reviewed. The research progress made at home and abroad is reviewed. Recent research work of the author′ task force is presented in detail, including the dynamic models, computer simulation, experimental validation, parameter identification and applications. Recommendations are made for the future research on the vehicle track coupling dynamics.
