Testing method and device for circulating air braking of locomotive intelligent driving system

The invention provides a testing method and device for circulating air braking of a locomotive intelligent driving system, and the method comprises the steps: obtaining an air braking force correction coefficient set corresponding to a to-be-tested line, and enabling the air braking force correction coefficient set to comprise the value ranges of air braking force correction coefficients of different application intensities of each air braking; according to the air braking force correction coefficient set, selecting the application intensity of each air braking of the to-be-tested line to form a combined sequence subset; and sequentially performing air braking on each time of the line to be tested, selecting an air braking force correction coefficient according to the combined sequence subset to correct the air braking force calculated by the air braking simulation model, and transmitting the corrected air braking force to the train operation simulation model to perform air braking test. And the circulating a
