The invention provides a gear shifting control method and system of a hybrid power system and electronic device.The gear shifting control method comprises the steps that after a vehicle is powered on, the synchronizer rotating speed difference of the hybrid power system is continuously obtained; judging whether the duration of the synchronizer rotating speed difference exceeding a preset rotating speed difference threshold value is greater than preset time or not; and if the duration of the synchronizer rotating speed difference exceeding the preset rotating speed difference threshold value is longer than the preset time, an out-of-gear fault is reported, and out-of-gear degradation protection is carried out. Therefore, compared with the scheme that the gear shifting driving system conducts out-of-gear judgment in the related technology, the synchronizer rotating speed difference serves as the out-of-gear judgment condition, and the out-of-gear fault detection accuracy and reliability can be improved.
