Suspension Damping Control Algorithms Using Vehicle States with Driver and Road Inputs (Second Report)

- Algorithm Configurations Based on Estimated States with Driver Inputs -

Abstract

When a vehicle runs with driver and road inputs, it is difficult to reduce vibrations of ride comfort and driving stability configuring conventional skyhook damping control suspensions. In this paper, vehicle vibrations for the driver inputs were estimated using vehicle dynamic models. A new control algorithm was proposed using the summation of conventional skyhook damping forces and estimated vibration suppressing forces for the driver. The estimated state accuracy and the vehicle performance were confirmed in actual vehicle tests.
