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

Abstract

The present invention relates to an active vibration damping control device and method for a hybrid vehicle. Provided are an active vibration damping control device and method of a hybrid vehicle for generating a reference signal of a first motor corresponding to a vibration signal extracted from a second motor. The amplitude and phase of the reference signal are adjusted based on the frequency characteristics of the drive system transfer function to generate damping torque of the first electric motor in the hybrid vehicle. A first electric motor, a torsional vibration damper, an engine, a connector (pulley, chain, gear, etc.), and a second electric motor are sequentially connected in a 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...
