The invention provides a hybrid power gearbox gear shifting device and a control method. Comprising an intermediate shaft, a gear shifting assembly connected to the intermediate shaft in series, a first motor assembly, a second motor assembly, a first rotary transformer arranged on the side, away from the gear shifting assembly, of the first motor assembly, and a second rotary transformer arranged on the second motor assembly, wherein the first motor assembly and the second motor assembly are connected with the two sides of the gear shifting assembly correspondingly. The gear shifting assembly comprises a first-gear gear shifting tooth and a second-gear gear shifting tooth which are connected with the first motor assembly and the first rotary transformer in series correspondingly, and a combined gear sleeve which is connected with the second motor assembly and the second rotary transformer in series correspondingly. The rotating speed information and the rotating angle information of the first gear shifting tooth and the second gear shifting tooth in the output process can be obtained through the first rotary transformer, and the rotating speed information and the rotating angle information of the combined gear sleeve in the output process can be obtained through the second rotary transformer. And the rotating speeds of the first gear shifting tooth, the second gear shifting tooth and the combined gear sleeve are adjusted according to the differential information, so that impact-free gear shifting is achieved.
