Abstract: The research on vehicle handling stability is of great significance to ensure the driving safety of the vehicle. In this paper, based on the Trucksim simulation platform, a reasonable passenger vehicle model is constructed according to the specific design parameters of the vehicle. After the parametric modeling of the whole vehicle, four tests closely related to the vehicle rollover are selected for simulation verification. The simulation results are in line with expectations and have high precision, each parameter index conforms to relevant regulations and driving safety requirements. After in-depth research and analysis of the simulation results, the influence of each parameter on the vehicle handling stability is obtained. The appropriate use of Trucksim has positive guiding significance for the early development and later experimental verification.
