Automatic calibration method and system for engine air system

The invention discloses an automatic calibration method and system for an engine air system. The automatic calibration system comprises a processor, a controller, a data acquisition device and a data storage device; the processor is used for loading and analyzing the calibration multi-dimensional table, and generating a test data input structure body according to the test logic; the controller controls the test data input structural body to be sequentially input into an engine air system for testing; the data acquisition device detects in real time to obtain multiple groups of output data and transmits the data to the processor; the processor compares the difference value between one group of output data and the previous group of output data with a preset error threshold value; and finally, based on a comparison result, it is determined whether to store the group of test data and the corresponding output data. The method and the system can be applied to calibration of working parameters of an air compressor a
