【Abstract】Based on the principle of energy conservation and data fusion,this paper constructs afuel consumption predictionmodel.Byemployingfeaturedimensionreduction,parameteridentification,andpiecewisefiting,whichaimsto balance accuracyandreal-time performance.Experimental results show that this method improvesthe predictionaccuracy andreduces thecomputationalload,providing technical supportforon-board energy-saving controland inteligent driving.

【Key words】 mathematical modeling;fuel consumption prediction; conservation of energy；feature dimensionality reduction;piecewise fitting
