ABSTRACT:
In an internal combustion engine, a vibration period and a vibration amplitude are measured when the surging of a vehicle is detected and the detected vibration period is compared with a natural vibration period prestored in accordance with a driving condition of the vehicle when the detected vibration amplitude is larger than a predetermined value, and if the detected vibration period is equal to the natural vibration period under the driving condition at which the vibration period is detected, surging due to variations of a combustion cycle of the engine is determined to be occurring, and accordingly, a surging reducing process is activated.
