Vehicle Dynamic Stability Improvements Through Gain-Scheduled Steering and Braking Control

Active Coordination of The Individually Actuated Wheel Braking and Steering To Enhance Vehicle Lateral Stability and Handling ⋆

In this paper, a novel vehicle dynamics controller is proposed by combining two control loops which are formed by the individually actuated wheel braking and steering regulator. The inner braking loop regulates the individual tire force generation and prevents tire force saturation with respect to tire slip. When the tire forces are regulated to operate in the linear region of their nonlinear c...

Discussion on "Integrated vehicle dynamics control via coordination of active front steering and rear braking"

This paper investigates the coordination of active front steering and rear braking in a driver-assist system for vehicle yaw control. The proposed control system aims at stabilizing the vehicle while achieving a desired yaw rate. During normal driving situations, active steering control is involved for braking collaborate together to ensure vehicle stability. The coordination of these actuators...

Modeling and Optimal Control of 4 Wheel Steering Vehicle Using LQR and its Comparison with 2 Wheel Steering Vehicle

In this paper, kinetic and kinematic modeling of a 4 wheel steering vehicle is done and its movement is controlled in an optimal way using Linear Quadratic Regulator (LQR). The results are compared with the same control of two-wheel steering case and the advantages are analyzed. In 4 wheel steering vehicles which are nowadays more applicable the number of controlling actuators are more than the...

Application of Braking/Traction Control Systems to the Scaled Active Steering Testbed in the Railway Vehicle

Active steering system of railway vehicles has proven its ability to bridge the gap between stability and curve friendliness. Generally scaled railway vehicles were developed to reproduce the fundamental dynamic behavior of the full size railway vehicle in laboratory conditions. This paper describes the design of the braking/traction control systems as a part of a 1/5 scaled railway vehicle for...
