The invention discloses a transmission system of a series-parallel hybrid oil-electric vehicle. The transmission system comprises a power battery, an auxiliary storage battery and a hybrid power control unit, wherein the input end of the hybrid power control unit is connected with an accelerator pedal position sensor, a gear position sensor, a braking sensor and a vehicle speed sensor separately; the first output end of the hybrid power control unit controls an engine to run through an engine control unit; the second output end of the hybrid power control unit controls a motor to work through a frequency changer; the third output end of the hybrid power control unit controls the output shaft of the engine to be connected with a gear ring in a single-row planetary gear mechanism through a first clutch; the output end of the hybrid power control unit controls the gear ring in the single-row planetary gear mechanism to be connected with a planet carrier through a second clutch. The transmission system disclosed by the invention has the advantages of being energy-saving and environment-friendly; the engine control unit and the hybrid power control unit can cooperate and coordinate with each other, so that the optimization of working modes is realized.
