The research course and main contents of vehicle-pavement interactions are reviewed, and the relationship between three research fields of vehicle system dynamics, tire dynamics and pavement structure dynamics is analyzed. The research progress was reviewed from three levels, including random vibrations of vehicle and pavement-friendly suspensions, tire-pavement contact dynamics, pavement structure dynamics under dynamic load, thus proposing the problems existing in the research on vehicle-pavement interactions as well as the future development direction. Currently, research on vehicle-pavement interactions mostly focuses on a single field or the simple superposition of three fields, but ignoring or simplifying the complex dynamic coupling relationship between vehicle-pavement interactions and mutual restraints. However, to meet the higher control accuracy and dynamic performance optimization of vehicles, the interactions between vehicles and pavements need to be considered. As for the tire-pavement contact relationship, most of the existing researches are based on the specific parameters of the pavement to describe the hysteresis characteristics of the tire itself. The dynamic coupling characteristics between the tire and the pavement needs to be further studied. The simple pavement roughness model is insufficient to describe the topography of the pavement, which restricts the study of vehicle-pavement interactions. It is still significant to conduct the extraction, description and reconstruction of the pavement topography. The realization of vehicle motion control and the design of the controller mostly depend on the dynamic response of the mass center and the pavement adhesion. The vehicle-tire-pavement transient coupling mechanism as well as the high-precision and rapid identification of pavement parameters will be very theoretically difficult with huge engineering application prospects. In addition, the application of in-wheel motors in the new generation of intelligent electric vehicles has changed the chassis configuration and load distribution of vehicles. Considering the comprehensive effects of pavement random excitation, motor excitation and vehicle-pavement coupling excitation, research on vehicle-pavement interactions and intelligent control is also a challenging scientific issue. © 2021 Journal of Mechanical Engineering.
