SYSTEM AND METHOD FOR CONTROLLING VIBRATION OF ENGINE

摘要

The present disclosure relates to a system for controlling vibration of an engine including an engine inertia portion which rotates together with the engine and a sub-inertia portion which influences a rotation speed of the engine and is separately provided, and a damper which is disposed between the engine inertia portion and the sub-inertia portion for reducing a vibration. The present disclosure includes: determining whether a vehicle is in an idle state; sensing rotation speeds of the engine inertia portion and the sub-inertia portion, respectively; calculating an average value of the rotation speeds of the engine inertia portion and the sub-inertia portion; calculating an error value from the average value; and PI controlling by receiving the error value.

1. A system for controlling vibration of an engine, including an engine inertia portion which rotates together with the engine and a sub-inertia portion which is separately provided in order to influence a rotation speed of the engine, and a damper which is disposed between the engine inertia portion and the sub-inertia portion for reducing a vibration, comprising:
an engine rotation speed sensor which senses a rotation speed of the engine inertia portion; a sub-rotation speed sensor which senses a rotation speed of the sub-inertia portion; and a control portion which receives each of the rotation speeds obtained from the engine rotation speed sensor and the sub-rotation speed sensor and stores signals which are converted from each of the rotation speeds, respectively, wherein the control portion is configured to control the rotation speed of the engine using an error value which is calculated by subtracting an average value which is between each of the rotation speeds obtained from the engine rotation speed sensor and the sub-rotation speed sensor, from a predetermined engine rotation speed value in an idle state.
