The invention relates to the field of hybrid electric vehicles, and provides a control method and device of a hybrid electric vehicle, a medium and the hybrid electric vehicle. The control method comprises the steps that operation parameters, driver demand power and limited power of the hybrid electric vehicle are obtained, and a first power influence factor system is constructed based on the operation parameters, the first power influence factor system comprises vehicle speed information, accelerator opening degree information, battery charge state information, brake information, engine regeneration request information and clutch information; and determining a first power influence degree based on the first power influence factor system, determining a first to-be-compared power based on the driver demand power, the limited power and the first power influence degree, and controlling switching of a pure electric mode and a hybrid mode of the hybrid electric vehicle based on a relation between the first to-be-compared power and a first preset power. In this way, mode switching can be accurately carried out according to the whole vehicle state, the driving intention of a driver and the whole vehicle power source change, and the mode switching quality of the hybrid electric vehicle is improved.
