<P>PROBLEM TO BE SOLVED: To prevent strong resonance and engine stop from occurring by performing a resonance prevention treatment at a proper timing while considering the state of the approach of the rotational speed of an internal combustion engine to the resonance rotational speed of a dual mass flywheel in controlling the internal combustion engine. Ž<P>SOLUTION: A reference rotational speed value A and a reference rotational speed variation amount value B are set according to an engine rotational speed deceleration Dne and a shift stage SFT (S112, S114). These values A, B are compared with an average rotational speed Nea and a rotational speed variation amount ΔNe (S116, S118). The state of the adjustment of the reference values A, B is changed by more increasing the reference rotational speed value A and more reducing the reference rotational speed variation amount value B as the engine rotational speed deceleration Dne is higher, and by making these values to correspond to the resonance rotational speed which changes according to the shift stage. Since the resonance prevention treatment can be performed at a proper timing, the strong resonance and the engine stop are prevented from occurring. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
