The invention provides a shifting method and a shifting system of a hybrid electric vehicle. The hybrid electric vehicle comprises an engine, a clutch, a synchronizer, an electric generator and a drive motor. The engine, the electric generator, the clutch and the drive motor are connected in series in turn; the clutch is connected to the electric generator and the drive motor. The shifting method comprises the steps of receiving a shifting instruction and quickly reducing torque of the engine through negative torque provided by the electric generator, and determining a target gear according to the shifting instruction; separating the clutch to perform shifting operation when the input torque of the clutch is less than the safety torque of the clutch. According to the shifting method disclosed by the embodiment of the invention, the clutch is separated to perform shifting operation when the input torque of the clutch is less than the safety torque of the clutch, thus the shifting time is reduced, the efficiency of power transmission is improved, emissions are reduced, and the service life of the clutch is prolonged.
