Problems solved by technology

[0008] However, we have found that when the vehicle is started or driven, the above structural approach can make the rumbling noise worse as the vibrations of the engine are directly transmitted
[0009] At the same time, according to the above control method of increasing the rotational speed when the engine is at idle, we have found that the fuel consumption and overall noise of the vehicle may be worse

Embodiment Construction

[0036] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0037] Throughout the specification, unless expressly stated to the contrary, the word "comprise" and variations thereof such as "comprises" or "comprises" will be understood to imply the inclusion of stated elements but not to the exclusion of any other elements.

[0038] figure 1 is a block diagram illustrating an engine drive system according to one form of the present disclosure.

[0039] refer to figure 1 , according to one form of the present disclosure, the engine drive system includes an engine inertial part 10 connected to the engine, an auxiliary inertial part 20 that has an effect on the engine speed, and a vibration damper disposed between the engine inertial part 10 and the auxiliary inertial par...

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2015-0131193 filed on September 16, 2015, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to systems and methods for controlling engine vibration. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] Generally, vehicles with a dual clutch transmission (DCT) or a dual mass flywheel (DMF) have external shock absorbers. Such vehicles can produce a certain amount of noise when the engine is idling. [0006] We have found that in a drive system in which the inertial part of the engine (such as the main flywheel) is connected to the auxiliary inertial part (such as the auxiliary flywheel) via a shock absorber, when the engine is in an idle state,...
