The invention relates to the field of a hybrid power vehicle, in particular to a double-mode planet series-parallel connecting system and a control system thereof. The double-mode planet series-parallel connecting system is characterized in that a torque sensor is connected between an output shaft of an engine and a planet row system in series, the torque sensor is connected with a whole vehicle controller, accurate torque Eng_Trq actually output by the engine can be obtained through the feedback of the torque sensor, and closed loop PI correction on the torque control of the engine is realized, i.e. (1) the situation that the torque output of the engine is enlarged when the torque is smaller than a target torque is realized; (2) the situation that when an actual torque is greater than the target torque, the engine stops outputting a target command, and a load of the engine is in reverse drawing is realized. When the double-mode planet series-parallel connecting system disclosed by the invention is used, analog quantity signals can be collected by the torque sensor in real time, a current actual torque value of the engine can be calculated by the whole vehicle controller according to the obtained analog quantity signals, accurate closed loop control on the engine can be realized through control strategy calculation, and thus the problem that working points of the engine of the planet row system cannot be accurately controlled is solved.
