Abstract (en)

[origin: EP0903257A2] When an accelerator pedal (25) is suddenly stamped on, the amount of fuel injected into an engine (12) increases sharply, and the rotating force of a crankshaft (14) is increased, so that when the rotation is transmitted from the shaft (14) to an automatic transmission (23), a force which tends to twist an automobile (11) in the rotating direction of the shaft (14) is applied to the automobile (11). Consequently, the automobile (11) vibrate in the back-and-forth direction, and variations occur in the engine speed. The variations in the engine speed and the vibrations of the automobile (11) are suppressed by executing fuel-injection-amount correction corresponding to the variations in the engine speed with a predetermined phase difference and an incremental pattern with respect to the variations. As the phase difference (θ) is thus provided, the output torque of the engine (11) which changes by lagging behind the fuel-injection-amount correction can be suitably regulated so as to suppress the variations in the engine speed. <IMAGE>
