The invention discloses a torque control system for an extended-range automobile engine. The torque control system comprises an automobile controller, a sensor module, a calculation module, a judgmentmodule and a setting module. The invention further provides a torque control method of the extended-range automobile engine. The influence of generator vibration on the engine speed is tested so thatrotating speed closed-loop control is carried out by taking the difference between the actual rotating speed and the target rotating speed as reference. The rotating speed output by an engine is morestable; the influence of engine output torque caused by generator vibration impact is reduced; the actual indication torque output by the engine is ensured to be close to the actually requested target torque; on the previous basis, the influence of generator vibration on the rotating speed of the engine is considered, it is ensured that the engine outputs stable indication torque to the generatorby correcting the torque, i
