Systematic Investigation of Longitudinal Dynamics' Influence on Dynamic Stability of In-Wheel Motor Driven Car-Trailer Combinations

The longitudinal dynamics' influence on dynamic stability of in-wheel motor driven car-trailer combinations is systematically investigated, including acceleration/deceleration, rolling resistance and aerodynamics. They are simply modeled and integrated into a single-track model with a tandem-axle trailer. On this basis, sensitivity analysis to the system dynamic critical speed can be achieved through simulation. Results can be adopted to explain the experimental phenomenon and serve as a guideline for the optimal design of the dynamics and stability of car-trailer combinations.
