METHOD FOR CONTROLLING DRIVING MODE SWITCHING OF HYBRID ELECTRIC VEHICLE, VEHICLE AND STORAGE MEDIUM

A method for controlling driving mode switching of a hybrid electric vehicle, the method comprising: when the driving mode of a hybrid electric vehicle is switched from a series driving mode to a parallel driving mode, adjusting a torque of an engine (1) to a target torque in the parallel driving mode, and adjusting the rotation speed of the engine to be the same as the current rotation speed of a driving electric motor (4); closing a clutch (3); and reducing a torque of an electric generator (2) to zero and synchronously reducing a torque of the driving electric motor by an adjustment amount of the torque of the electric generator; and when the driving mode of the hybrid electric vehicle is switched from the parallel driving mode to the series driving mode, increasing the torque of the electric generator to absorb the torque of the engine, and transferring, to the driving electric motor and with the same amplitude, the torque absorbed by the electric generator; releasing the clutch; and adjusting the torque and the rotation speed of the engine to a target torque and a target rotation speed of the engine in the series driving mode respectively. Also disclosed are a vehicle and a storage medium.
