The embodiment of the invention discloses a mode switching control method and device for a transmission, electronic equipment and a storage medium, and the method comprises the steps that under the condition that it is detected that a to-be-controlled vehicle is switched from a range extending mode to a direct drive mode, the engine rotating speed synchronization difference, the engine torque reduction value and the accelerator pedal opening degree are obtained; determining clutch engagement time according to the opening degree of the accelerator pedal; rotating speed synchronous control is carried out according to the engine rotating speed synchronous difference and the engine torque reduction value, so that the engine rotating speed is in a coupling state; when the engine speed is in the coupled state, the clutch is controlled to engage at an interval of the clutch engagement time. Therefore, on one hand, rotating speed synchronous control is carried out through the engine rotating speed synchronous difference and the engine torque reduction value, and active speed regulation of the generator and rapid torque reduction of the engine can be achieved; and on the other hand, by setting the clutch engagement time, driving smoothness can be guaranteed, meanwhile, it can be ensured that dynamic response follows in time, and the dynamic property and the NVH performance are improved.
