Problems solved by technology

However, in the first method, the optimal operating point is deviated; in the second method, the vibration reduction effect is low due to the limitation of low stiffness; and in the third method, the fuel consumption is degraded due to the weight increase , and increases manufacturing costs by incurring additional charges

Embodiment Construction

[0045] It should be understood that the term "vehicle" or "vehicular" or other similar terms as used herein includes motor vehicles in general, such as passenger cars (including sports utility vehicles (SUVs)), buses, trucks, various commercial vehicles , watercraft (including boats and ships of all kinds), aircraft, etc., and includes hybrid vehicles, electric vehicles, plug-in hybrid electric vehicles, hydrogen-powered vehicles and other alternative fuel vehicles (for example, those derived from sources other than petroleum fuel). As referred to herein, a hybrid vehicle is a vehicle that has two or more sources of power, eg, a vehicle that is both gasoline-powered and electric-powered.

[0046] Although the exemplary embodiment is described as using a plurality of units to perform the exemplary process, it should be understood that the exemplary process may also be performed by one or a plurality of modules. Furthermore, it should be understood that the term controller / cont...

Abstract

An active vibration reduction control apparatus and method of a hybrid vehicle are provided to generate a reference signal of a first motor that corresponds a vibration signal extracted from a second motor. An amplitude and phase of the reference signal is adjusted based on frequency characteristic of a drive system transfer function to generate vibration reduction torque of a first motor within the hybrid vehicle. The first motor, a torsional damper, an engine, a connector (a belt-pulley, a chain, a gear, and so on), and the second motor are sequentially connected within the hybrid vehicle.

Description

technical field [0001] The present disclosure relates to an active vibration damping control device and method for a hybrid vehicle, and more particularly to a method for extracting a vibration signal (vibration component) transmitted via a drive system (power system) during an explosion stroke of an internal combustion engine and converting the extracted A technology in which the reverse phase torque of the vibration signal is applied to the electric motor installed in the drive system to actively reduce vibration due to engine knock. Background technique [0002] A hybrid vehicle refers to a type of eco-friendly vehicle that is driven by efficiently combining two or more types of different power sources, and in general, refers to a ) to obtain rotational power with an engine and a motor driven vehicle using battery power to obtain rotational power. [0003] The engine generates rotational power through combustion pressure during the cylinder explosion stroke. In particul...
