A Novel Method for the Reconstruction of Road Profiles from Measured Vehicle Responses Based on the Kalman Filter Method

The estimation of the disturbance input acting on a vehicle from its given responses is an inverse problem. To overcome some issues related to ill-posed problems, this work proposes method reconstructing road roughness based Kalman filter method. A half-car model that considers both and equipment established, joint input-state used identify profile. capabilities methodology in presence noise are numerically demonstrated. Moreover, reduce influence driving speed results, choosing calculation frequency proposed. vibration test conducted benchmark proposed
