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.
