The invention provides an automobile hybrid power system, and belongs to the technical field of automobiles. The problems that an existing automobile engine shakes during intervention and retreating, the fuel economy is poor, reverse gear power is insufficient under the condition that the electric quantity of a power battery is insufficient, and a transmission is difficult to arrange due to the 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 gear ring, 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 planet carrier clutch and a brake capable of braking the planet carrier, the planet carrier clutch is used for achieving transmission connection or disconnection between the planet carrier 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.
