Abstract
An application method of ICA on vibration of an automobile considering dynamical properties is introduced and its performance is examined through a numerical simulation using a half car model. The proposed method separates mixed signals considering dynamical properties, while original ICA assumes a static mixture. Also, methods for fixing order of independent components and amplitude are proposed for the estimation of road irregularity. By applying the proposed method, road irregularity with information of amplitude is estimated without knowing parameters such as mass and spring constant.
