THE SYSTEM FOR CONTROLLING CONTINUOUS VARIABLE MR DAMPER USING VEHICLE BODY ACCELERATION AND DAMPER RELATIVE DISPLACEMENT

摘要

The present invention relates to a continuously variable MR damper control system using the vehicle body acceleration and the relative displacement of the damper, using four vertical acceleration sensors attached to the vehicle body and the relative displacement sensor of the four dampers, It is a characteristic object of the present invention to provide a system for controlling a magnetic fluid damper by classifying the characteristics of a road surface being driven.;The present invention for achieving this object relates to a continuously variable MR damper control system using the vehicle body acceleration and the relative displacement of the damper, by using the acceleration value of the vehicle body and the relative displacement value of the damper, the moving average value of the vehicle body speed and A signal processor for obtaining a moving average value of wheel relative speeds; A control gain calculation unit which receives a moving average value of the vehicle body speed and a moving average value of the wheel relative speed from the signal processor, determines a road surface, and calculates a control gain accordingly; And a damper controller configured to drive a damper based on a control gain value calculated through the control gain calculator, a signal value of the vehicle body resonance frequency band extracted from the signal processor, and a signal value of the resonance frequency band of the wheel. Characterized in that it comprises a.;Magnetic Fluid Damper, Acceleration, Control Gain
