Hybrid power system and vehicle with same

The utility model discloses a hybrid power system and a vehicle with the hybrid power system. The hybrid power system comprises an engine, a power source and a controller, a driving motor; the transmission comprises a first input shaft, a second input shaft, an output shaft, a speed reduction mechanism and a speed change mechanism, the first input shaft is connected with the engine, the second input shaft is connected with the driving motor, the speed reduction mechanism is arranged between the first input shaft and the output shaft, and the speed change mechanism is arranged between the output shaft and the output shaft. The first input shaft is selectively in transmission connection with the output shaft, the speed change mechanism is arranged between the second input shaft and the output shaft, so that the second input shaft is selectively in transmission connection with the output shaft, and the speed change mechanism is provided with at least two gears and selectively switches the at least two gears. According to the hybrid power system, the engine can be kept in an efficient working interval, the vehicle speed coverage range of the driving working condition of the driving motor is wider, and economical efficiency and dynamic property are both considered.
