Zusammenfassung:The invention provides a dead zone identification and compensation control method for a power system, a vehicle and a storage medium. The dead zone identification and compensation control method for the power system comprises the steps that a mathematical model and a first simplified model for complete torque transmission of the power system are established; discretizing the first simplified model to obtain a segmented nonlinear equation set which comprises a first dead zone boundary cl (p), a second dead zone boundary cr (p) and dynamic characteristics; iteratively solving the first dead zone boundary cl (p), the second dead zone boundary cr (p) and the dynamic characteristics to obtain a second simplified model; designing a full-dimensional state observer according to the second simplified model, and predicting rotating speed output and input torque through the full-dimensional state observer; and performing feedback control and selecting an optimal point according to the second simplified model, the rotati
