Title:
METHOD AND APPARATUS FOR CONTROLLING DEGREE OF ROTATIONAL SMOOTHNESS OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPH04219443
Kind Code:
A
Abstract:
PURPOSE: To provide a method and apparatus to damp approximately all vibrations generated and control smooth rotation.
CONSTITUTION: A closed loop control or open loop control is conducted for the degree of smoothness in rotation in accordance with the applicable operating condition. The rotational smoothness control with the closed loop is shut when the frequency F of the control deviation DN reaches the limit value or the absolute of the control deviation goes beyond the threshold.
