The invention discloses a vehicle data generation method and device, equipment and a storage medium, and relates to the technical field of vehicles, and the method comprises the steps: obtaining a plurality of groups of first historical vehicle data needed by a target scene; preprocessing is carried out on the basis of the relevancy among the multiple parameters of the first historical vehicle data, multiple sets of second historical vehicle data are obtained, and the relevancy among the multiple parameters of the multiple sets of second historical vehicle data is lower than a preset relevancy threshold value; based on the multiple groups of second historical vehicle data, multiple groups of Gaussian mixture models are constructed, and the numbers of aggregation points corresponding to the Gaussian mixture models are different; evaluating the plurality of Gaussian mixture models based on a Bayesian information criterion and/or an akaike information criterion; screening out a target Gaussian mixture model from
