The invention belongs to the technical field of automobile power control, and particularly relates to a gear shifting method of a gearbox and application of the gear shifting method. The invention provides a gear shifting method of a gearbox. The gear shifting method comprises the steps of torque redistribution, gear shifting fork detection, gear shifting execution and torque returning. The invention further provides application of the gear shifting method in new energy automobile gearbox software control. According to the technical scheme, in the torque redistribution step, after the rotating speed reaches the preset gear shifting rotating speed, one motor gradually stops outputting the torque to complete gear shifting, and the other motor continuously outputs the torque and tends to be gradually increased, so that the loss caused by torque reduction is made up, it is guaranteed that the torque can be continuously output in the gear shifting process, and the gear shifting efficiency is improved.
