Hydrogen fuel cell vehicle endurance mileage prediction method based on XGBoost algorithm

Abstract

The invention discloses a hydrogen fuel cell vehicle endurance mileage prediction method based on an XGBoost algorithm, the core of the method is that an algorithm model is preset, the algorithm model is an XGBoost (eXtremeGradient Boosting, extreme gradient boosting) algorithm, the method comprises the following steps: firstly, obtaining various current related data of a vehicle, analyzing and judging the current vehicle working condition, and also obtaining vehicle fuel cell data, hydrogen system data and other vehicle data, performing proportional combination on the current data and historical data corresponding to the vehicle working condition and then inputting into the algorithm model, and predicting a future consumption curve of hydrogen under the current working condition. The algorithm has the advantages that the algorithm model required by the current operation for predicting the endurance mileage is optimized and adjusted by continuously utilizing the residual error of the previous algorithm model so that the algorithm model required by the prediction operation is more and more convergent along with the increasing and increasing of the data volume and the increasing and increasing of the number of iterations, and the prediction precision is continuously improved.
