The invention discloses an automobile hybrid power system which comprises an engine, a first brake, a second brake, a third brake, a first clutch, a second clutch, a motor, a planetary gear mechanism and an output gear mechanism. According to the automobile hybrid power system, the engine and the motor are connected through the planetary gear mechanism, meanwhile, power output is conducted through the output gear mechanism, three driving modes of a pure electric driving mode, a range extending power generation mode and a hybrid power mode can be achieved, and stepless speed regulation is achieved while torque output is conducted; the three driving modes can be freely switched in a full vehicle speed range; a pure electric drive mode, a range extending mode, a power dividing mode and two direct drive modes with different speed ratios can be achieved, loss is reduced, and the efficiency of an automobile hybrid power system is improved. And only one motor is used while a multi-drive mode is realized, so that the cost is reduced, and the economic applicability of the automobile hybrid power system is improved.
