Abstract

Natural wind and the road itself brings the airflow changes, together constitute the vehicle driving process of the side wind environment. It directly affects the vehicle's operational safety and driving stability. On the basis of the domestic research on driving safety under the wind outside, this paper collects the unsteady flow parameters on the real road to establish a database of crosswind aerodynamic test conditions with regional characteristics, obtains and analyzes the air, vehicle and other parameters to analyze the change trend of crosswind, and uses a single factor to analyze the specific influencing factors of crosswind environment on vehicle driving safety. The driving simulation experiment in crosswind environment is carried out by using the dynamics simulation software CarSim to evaluate the driving safety and stability in crosswind environment. The air flow characteristics of the change of side wind environment have a great influence on driving safety and driving stability, and through the analysis and simulation of road measurement data, it is very important to analyze the factors influencing the safety of vehicle operation and the stability of driving.
