Gasoline engine starting calibration control parameter optimization method

The invention discloses a gasoline engine starting calibration control parameter optimization method. The method comprises the steps of acquiring starting calibration control parameters and starting weighting target parameters; performing dimensionality reduction on the starting calibration control parameters based on a contribution degree relation model between the starting calibration control parameters and the starting weighting target parameters; and establishing a final relationship model based on the relationship between the starting calibration control parameters and the starting weighting target parameters after dimension reduction. According to the method, the gasoline engine starting calibration parameter optimization time can be effectively shortened, a reasonable and effectivestarting control optimization direction can be given, and the method has great benefits for shortening the gasoline engine starting calibration development period and accumulating starting calibrationdevelopment experience. 本
