The invention provides an engine control method and device of a hybrid vehicle, the vehicle and a storage medium, and belongs to the technical field of vehicles. The method comprises the following steps: determining a charging coefficient based on the speed of the hybrid vehicle, the current SOC, the target SOC and the road surface type of the road surface; when the charging coefficient indicates that charging is conducted through the engine and the speed of the hybrid vehicle is not larger than a first threshold value, the hybrid vehicle enters a range extending mode, and a first corresponding relation is obtained based on the charging coefficient; determining driver demand power of the hybrid vehicle based on the vehicle speed and the pedal torque of the hybrid vehicle; determining generated power corresponding to the driver demand power based on the first corresponding relation and the determined driver demand power; and based on the generated power, the rotating speed and torque located in the economic area are determined, and the engine is controlled to charge the hybrid vehicle according to the rotating speed and the torque. According to the scheme, the engine is controlled in the economic area, and the economical efficiency of the hybrid vehicle is improved.
