[0002] Gasoline engine starting calibration control faces the problems of complex control strategy, many control parameters, and difficult parameter adjustment
Relying on experience to adjust the starting calibration control parameters such as fuel injection, ignition and intake air, it is impossible to make fuel injection, ignition and intake control reasonable or optimal in a short time
Poor fuel injection, ignition, and air intake control will make it difficult to start the gasoline engine, worsen fuel consumption and emissions, and reduce vehicle comfort; good fuel injection, ignition, and intake control can reduce gasoline engine fuel consumption and emissions, and ensure gasoline engine starting reliability , to improve the NVH performance of the vehicle; at the same time, consumers’ requirements for vehicle performance have increased, and gasoline engine electronic control systems have become increasingly complex, making it more difficult to optimize gasoline engine start-up calibration control parameters based on experience

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.
