Аннотация: Mongolians countryside road traffic occurring fatal accident many times in the years. Therefore sedan car accident concern 92.5 percent in total fatal accidents, tractor heavy vehicle accident concern 3.7 percent, bus accident concern 1.5 percent. Fatal accident occurring in countryside road 395 last year, metropolitan road 112 last year. Cause of fatal accident is depending on driver’s control, road condition, car’s technical problem, crosswind condition. This paper concerning crosswind condition car fatal accidents. Prius series car lighter weight for improving power performance and reducing fuel consumption, a prius with higher-speed and lighter weight will lead to the prius more sensitive to the crosswind, which will affect the stability and drivability of the prius. This paper employs the fully-coupled method to investigate a prius subjected crosswind with consideration of the car motion. Lattice-Boltzmann and dynamic mesh is adopted to investigate the unsteady aerodynamic, and the vehicle is treated as a three-freedom-system and driver’s control is considered to investigate the vehicle dynamic. Crosswind stability and drivability of high-speed prius has attracted more and more attention during the last decades, in order to promote vehicle aerodynamic design and technology to a higher level. Crosswind may threaten the safety of the running vehicle due to the unsteady aerodynamic loads (Cai 2015). Many reports (Wang et al. 2014) show that the crosswind is a significant factor causing the vehicle accidents.
