Road-Adaptive Nonlinear Design of Active Suspensions
Recently we proposed a novel nonlinear control design for active suspensions, which features a lter whose band-width is a nonlinear function of suspension travel; this lter results in an improved tradeoo between ride comfort and rattlespace usage. In this paper we augment this controller with a new road-adaptive algorithm which continuously monitors suspension travel and adjusts on-line the sha...
متن کاملExperimental Evaluation of Semiactive Magneto- Rheological Suspensions for Passenger Vehicles
Mechanical Engineering This study experimentally evaluates the dynamic response of a single vehicle suspension incorporating a magneto-rheological (MR) damper. A full-scale two-degree-of-freedom (2DOF) quarter-car test apparatus has been constructed at the Advanced Vehicle Dynamics Lab at Virginia Tech to evaluate the response of a vehicle suspension under the different control schemes of skyho...
متن کاملAdaptive Super-Twisting Observer for Estimation of Random Road Excitation Profile in Automotive Suspension Systems
The estimation of road excitation profile is important for evaluation of vehicle stability and vehicle suspension performance for autonomous vehicle control systems. In this work, the nonlinear dynamics of the active automotive system that is excited by the unknown road excitation profile are considered for modeling. To address the issue of estimation of road profile, we develop an adaptive sup...
متن کاملRoad Condition Estimation Based on Heterogeneous Extended Floating Car Data
Road condition estimation based on Extended Floating Car Data (XFCD) from smart devices allows for determining given quality indicators like the international roughness index (IRI). Such approaches currently face the challenge to utilize measurements from heterogeneous sources. This paper investigates how a statistical learning based self-calibration overcomes individual sensor characteristics....
متن کاملVibration of Road Vehicles with Non linear Suspensions
In order to investigate the effects of non-linear springs in vibrating behavior of vehicles, the independent suspension of conventional vehicles could be modeled as a non-linear single degree of freedom system. The equation of motion for the system would be a non-linear third order ordinary differential equation, when considering the elasticity of rubber bushings in joints of shock absorber. It...
