Beschreibung
Zusammenfassung:	The invention provides a sequential supercharged engine and a transient loading method and device thereof, and relates to the technical field of electromechanics, the method comprises the steps that the operating parameter change rate of the sequential supercharged engine is obtained in real time, and the sequential supercharged engine comprises a plurality of superchargers; and if the running parameter change rate exceeds a preset threshold value, it is determined that transient loading happens to the sequential supercharged engine, and an intake and exhaust bypass valve of the sequential supercharged engine is controlled to be opened. Therefore, by taking the operating parameter change rate capable of reflecting transient loading of the sequential supercharged engine as the threshold value, transient loading is performed and the intake and exhaust bypass valve of the sequential supercharged engine is opened when the operating parameter change rate exceeds the threshold value, so that the transient loading r
