Abstract: A method and a device for controlling mode switching of a hybrid electric vehicle, and a vehicle is provided, and belongs to the field of hybrid electric vehicles. The method includes: performing, if the drive state information indicates that a current drive mode of the hybrid electric vehicle is a forward mode of a non-hybrid drive and in a case that a current speed reaches a speed limit, a pre-gear operation when a transmission gear of the hybrid electric vehicle is a neutral gear, to switch the transmission gear from the neutral gear to a second gear. The technical solution provided by the embodiments of the present disclosure can make the hybrid electric vehicle unable to switch to the hybrid drive mode due to the limitation of the ability of synchronizer on gear shifting when driving at a high speed.
