The invention provides an automobile hybrid power system, and belongs to the technical field of automobiles. The problems that an engine of an existing automobile hybrid power system intervenes in and exits from the system and shakes, fuel economy is poor, reverse gear power is insufficient when the electric quantity of a power battery is insufficient, and a transmission is difficult to arrange due to too long axial distance are solved. The automobile hybrid power system comprises an engine, a generator, a planetary gear train, a power transmission shaft and a driving motor in transmission connection with the power transmission shaft, an output shaft of the engine is in transmission connection with a planet carrier, and a rotating shaft of the generator is in transmission connection with a sun gear. The hybrid power system further comprises a sun gear clutch, a gear ring clutch and a brake capable of braking the gear ring, the gear ring clutch is used for achieving transmission connection or disconnection between the gear ring and the power transmission shaft, and the sun gear clutch is used for achieving transmission connection or disconnection between the sun gear and the power transmission shaft. The automobile hybrid power system has the advantages of being good in NVH performance, good in fuel economy, high in reverse gear power performance and the like.
