For this study, air resistance coefficient (CD), lift coefficient (CL) according to changes in inter-vehicle distance, driving speed, and inter-vehicle separation distance of crossing vehicles, and yawing moment and rolling moment affecting the driving stability of vehicles was calculated and the driving stability of the relative movement vehicle was judged based on the result. According to the results, the lower the vehicle speed, the greater the lateral distance between the two vehicles, and the more stable the vehicle.
