Calibration method and system for engine intake model, and computer readable storage medium

Abstract

The invention provides a calibration method and system for an engine intake model, and a computer readable storage medium. The calibration method comprises the steps that experimental design data areread, and the experimental data comprise a plurality of variable valve timing combinations and a plurality of to-be-calibrated working conditions; one of the variable valve timing combinations in theexperimental data is set as the target variable valve timing combination; the variable valve timing combinations of an engine are adjusted to be the target variable valve timing combinations step by step; parameters of the engine are adjusted step by step, so that the engine is adjusted to be in the to-be-calibrated working conditions, and operation parameters of the engine under the to-be-calibrated working conditions are measured; and after all the to-be-calibrated working conditions are calibrated, the other variable valve timing combinations in the experimental data are set as the target variable valve timing combinations in sequence. According to the calibration method and system for an engine intake model, the engine can be accurately adjusted to be in the to-be-calibrated working conditions, and the problems that the engine calibration efficiency is low, precision is insufficient, and safety performance is insufficient are solved.
