The embodiment of the invention provides a driving condition construction method and device. The method can comprise the steps: collecting driving record data of a target vehicle, and carrying out segmentation of the driving record data to obtain condition fragments; obtaining characteristic parameters corresponding to the working condition fragments, and grouping the working condition fragments according to the characteristic parameters to obtain working condition groups; and calculating an evaluation value of each working condition fragment in the working condition group, determining a target working condition fragment according to the evaluation value, and constructing a driving working condition corresponding to the working condition group through the target working condition fragment.In the embodiment of the invention, the driving record data do not need to be tested and acquired under artificially specified conditions, the cost is low, and human interference is little; the evaluation values calculated according to the characteristic parameters of the working condition fragments can actually reflect the quality of the working condition fragments, so that target working condition fragments selected according to the evaluation values can construct more accurate driving working conditions; and grouping of different road types can be performed on the working condition fragments according to the characteristic parameters so as to adapt to wider actual scenes.

    本发明实施例提供了一种行驶工况构建方法及装置,该方法可以包括:采集目标车辆的行车记录数据,并对行车记录数据进行分段获得工况片段;获取工况片段对应的特征参数,根据所述特征参数对工况片段进行分组,获得工况分组;并计算工况分组中每一个工况片段的评价值,根据评价值确定目标工况片段,再通过目标工况片段构建工况分组对应的行驶工况。本发明实施例中,行车记录数据无需人为指定条件进行试验采集,成本低,人为干扰少;其次,根据工况片段的特征参数计算的评价值能够实际反应工况片段质量,使得根据评价值选择的目标工况片段可以构建更准确的行驶工况;最后,可以根据特征参数对工况片段进行不同道路类别的分组,适应更广泛的实际场景。
