In order to explore the reason of lateral instability of automobile passing by the pylon zone of cablesupported bridge under cross wind, a new evaluation method of lateral driving stability of automobile considering alternative cross wind is established based on multi-objective driving stability criteria and subjective assessment. Typical driving control process and dynamic response of automobile passing by the pylon zone is given by numerical simulation based on steering wheel fixed-control model and straight driving ideal-driver model. Finally, taking a medium-size commercial bus as an example, the reason of its lateral instability is interpreted and the influence of cross wind speed and driving speed on its lateral driving stability is shown by parameter study.
