Journal ArticleDOI
Dual extended Kalman filter for vehicle state and parameter estimation
TL;DR: In this paper, the dual extended Kalman filter (DEKF) technique is used for combined estimation of vehicle states and parameters, which can be used to switch off the parameter estimator, once a sufficiently good set of estimates has been obtained.
Journal ArticleDOI
Kalman filter as a virtual sensor: applied to automotive stability systems:
TL;DR: In this paper, the authors demonstrate the use of an extended Kalman filter (KF) as a virtual sensor for non-measurable vehicle states and unknown vehicle parameters.
Proceedings ArticleDOI
Closed-loop driver/vehicle model for automotive control
TL;DR: In this paper, the authors demonstrate the implementation of a comprehensive vehicle model combined with a driver model in closed loop for the purpose of developing and testing of vehicle stability systems, using a model of an active front steering controller.
Journal ArticleDOI
Control of a hydropneumatic active suspension based on a non-linear quarter-car model
TL;DR: In this article, it is shown that maintaining simultaneously a high standard of ride, handling, and body control in a vehicle with a conventional passive suspension is extremely difficult, and it is well known that it is difficult to maintain simultaneously high ride, body control, and ride quality.
Hybrid genetic algorithms / extended kalman filter approach for vehicle state and parameter estimation
TL;DR: In this article, a hybrid approach to estimate the states and parameters of a vehicle is described. But the results of the approach when applied to a four-wheel-vehicle model and the advantages and limitations are discussed.
