In order to investigate the crosswind stability, the new prediction methods of transient inputs are considered in this paper. One is the measuring method on the road, the other is the prediction of the inputs from the stationary data in the wind tunnel. The conclusions are followed. By means of the investigation of the pressure profile at each time measured on the adequate nominal points of body surface, reasonable transient aerodynamic forces and moments when passing through crosswind can be obtained. The transient inputs caused by crosswind can be predicted approximately from the stationary pressure date measured in the wind tunnel. In this case, it is important to consider the response of pressure according to the turbulence of the flow.
