The invention provides a hybrid power transmission system of an automobile, and belongs to the technical field of automobiles. The problem that the rotational inertia of an output shaft in an existing transmission transmission system is high is solved. The hybrid power transmission system of the automobile comprises an engine, an output shaft, four planetary gear trains, a second clutch, a motor connected with the output end of the engine and an input shaft connected with the motor. The four planetary gear trains are a second planetary gear train of which a second planet carrier is connected with the input shaft, a first planetary gear train of which a first sun gear is connected with a second sun gear of the second planetary gear train, a third planetary gear train of which a third sun gear is connected with a second outer gear ring of the second planetary gear train, and a fourth planetary gear train; a third planet carrier of the third planetary gear train is connected with a fourth planet carrier of the fourth planetary gear train through the second clutch, and the fourth planet carrier of the fourth planetary gear train is connected with the output shaft. The hybrid power transmission system of the automobile achieves the purpose of reducing the rotational inertia of the output shaft, so that the output efficiency is higher.
