PROBLEM TO BE SOLVED: To provide a torque control device for an internal combustion engine capable of controlling engine torque in suitable timing based on a rotation state of the internal combustion engine without being influenced by detection error of a rotation speed sensor in acceleration and deceleration of a vehicle, and capable of surely restraining longitudinal vibration caused by resonance of a driving system. SOLUTION: This torque control device restrains a throttle opening THfnl to be almost a half when acceleration operation is performed in order to accelerate, and releases torque restraining when a delay period corresponding to a quarter of a resonance cycle of the driving system passes after engine acceleration dNe which is a differential value of an engine rotation speed Ne is reversed from positive to negative. Reverse of the vehicle acceleration when the engine torque is increased first is offset by second increase of the engine torque. COPYRIGHT: (C)2007,JPO&INPIT
