The invention provides a hybrid power transmission system which comprises a generator, a driving motor, an engine and an output shaft, the output end of the driving motor is connected with the output shaft through a first transmission set, and the output end of the engine is connected with a planetary gear mechanism and a second synchronizer. The output end of the generator is provided with a second transmission group and a third transmission group which are distributed in parallel; the left side of the second synchronizer is connected with the third transmission group when being combined; the hybrid power transmission system further comprises a first synchronizer, and the first synchronizer is used for transmitting power of the generator or the engine to the output shaft. According to the multi-mode use of the hybrid power transmission system provided by the invention, the optimal working point of the engine can be optimized in real time, and the fuel economy is improved; the structure is simple and carrying is easy; different gears can be combined through the first synchronizer and the second synchronizer, the range extending mode, the ECVT mode and the pure electric mode are achieved, and the modes are more flexible.
