The invention relates to a vehicle out-of-control state analysis method and device for a long longitudinal slope section of an expressway, and relates to the field of vehicle state analysis. The method comprises the following steps: acquiring road condition data of a long longitudinal slope section; dividing multiple groups of road unit sections based on the inflection port information; based on the segmented road surface information, the segmented road surface state of the road unit segment is judged; when the segmented pavement state is responded to be a pavement high-risk state, the high-risk type of the segmented pavement is judged based on the segmented pavement information, and a first segmented out-of-control parameter is determined; when the segmented road surface state is a road surface normal state in response, whether the segmented road surface has a high-risk type is judged based on the segmented road information, and if the segmented road surface has the high-risk type, a second segmented out-of-control parameter is determined; and determining an out-of-control risk level based on the multiple groups of first section out-of-control parameters and/or the multiple groups of second section out-of-control parameters. According to the method, the dimension of data analysis can be increased by judging the road surface information and the road information, so that the problem of low accuracy of out-of-control analysis is avoided.

    本发明涉及一种针对高速公路长纵坡段的车辆失控状态分析方法及装置,涉及车辆状态分析领域。该方法包括:获取长纵坡段的路况数据;基于拐口信息划分多组道路单元段;基于分段路面信息判断道路单元段的分段路面状态;响应于分段路面状态为路面高危状态时,基于分段路面信息判断分段路面的高危类型,并确定第一分段失控参数;响应于分段路面状态为路面正常状态时,基于分段道路信息判断分段路面是否具有高危类型,若具有高危类型,则确定第二分段失控参数;基于多组第一分段失控参数和/或多组第二分段失控参数确定失控风险等级。该方法通过对路面信息和道路信息的判断,能增多数据分析的维度,从而避免失控分析精准度低的问题的发生。
