The invention relates to the technical field of hybrid electric vehicles, in particular to a gear shifting reminding method of a hybrid electric vehicle. The method comprises the steps that under the condition of meeting a gear shifting activation condition, the running parameters of the hybrid electric vehicle are obtained, and comprise the current vehicle speed, the current engine rotating speed, the current engine output torque and the current motor output torque; the current gear value is calculated according to the proportional relation between the current vehicle speed and the current engine rotating speed; upshift target vehicle speed and down-shift target vehicle speed corresponding to the current gear value are determined through the sum of the current engine output torque and the current motor output torque; if the current vehicle speed is larger than the upshift target vehicle speed, a user is reminded of upshift information; and if the current vehicle speed is smaller than the down-shift target vehicle speed, the user is reminded of down-shift information. By means of the method, optimal fuel economy gear recommendation is carried out, and a driver is helped to achieve the aim of improving the fuel economy of the hybrid electric vehicle.
