The invention belongs to the technical field of vehicle hybrid power systems, and particularly relates to a dual-motor automatic transmission range-extending hybrid power driving system and an automobile using the same. The dual-motor automatic transmission range-extending hybrid power driving system comprises an engine, a generator and a motor, the power generation main shaft and the electric main shaft are rotationally connected with an electric coupling gearbox. The electric coupling gearbox is used for being connected with a power output shaft. The electric coupling gearbox comprises a gear executing mechanism, a mode switching mechanism and a gearbox intermediate shaft connected with the gear executing mechanism and the mode switching mechanism. The gear executing mechanism realizes the connection or disconnection of the electric main shaft and the power output shaft; and the mode switching mechanism realizes connection or disconnection of the power generation main shaft and the power output shaft. According to the invention, multiple driving modes are realized; pure motor driving energy consumption at a high speed is reduced, and the power following performance and the climbing performance are improved; matching speed ratios of the engine and the generator; the system is compact and reliable in structure and efficient in power transmission.
