Zusammenfassung:	In order to solve a technical problem that switching between an ISG path and an EFAD path cannot be performed, the present invention provides a control method for switching a torque output path of a motor of a hybrid electric vehicle, which includes: acquiring an initial path state of a torque output path of a motor; acquiring an initial vehicle speed of the vehicle; acquiring a brake pedal opening; acquiring an initial accelerator pedal opening; acquiring an initial state of charge of a vehicle battery; if the initial path state is the ISG path, the initial state of charge is less than a first preset value, the initial vehicle speed is less than a second preset value and the initial accelerator pedal opening is greater than a third preset value, controlling the torque output path of the motor to be transitioned from the ISG path to the EFAD path; if the initial path state is the EFAD path, the initial state of charge is less than the first preset value, the brake pedal opening is greater than a fourth preset value and the initial vehicle speed is greater than a fifth preset value, controlling the torque output path of the motor to be transitioned from the EFAD path to the ISG path. The invention improves the drivability, comfort and safety of the vehicle.
