The invention relates to a power transmission device, a hybrid electric vehicle and a control method of the hybrid electric vehicle. The power transmission device comprises an engine, a generator, a driving motor, a planetary gear transmission mechanism, a synchronizer, a brake, a first transmission shaft, a second transmission shaft, a first-third gear output gear, a second-gear input gear and a second-gear output gear meshed with the second-gear input gear. Wherein the engine is in transmission connection with the generator through the first transmission shaft, and the first transmission shaft is driven by the engine to achieve the power generation function of the generator; the planetary gear transmission mechanism comprises a gear ring, and a planet wheel, a planet carrier and a sun wheel which are connected in the gear ring; the sun gear and the synchronizer are fixedly connected to the first transmission shaft; the first-gear and third-gear output gear and the second-gear output gear are fixedly connected to the second transmission shaft, and the first-gear and third-gear output gear is further meshed with the planet carrier. The driving motor is in transmission connection with the second transmission shaft. Multiple driving modes can be provided, and the dynamic property and economical efficiency can be effectively improved.
