Improving rollover and stability of the vehicles is the indispensable part of automotive research to prevent vehicle rollover and crashes. The main objective of this work is to develop active control mechanism based on fuzzy logic controller (FLC) and linear quadratic regulator (LQR) for improving vehicle path following, roll and handling performances simultaneously. 3-DOF vehicle model including yaw rate, lateral velocity (lateral dynamic) and roll angle (roll dynamic) were developed. The controller produces optimal moment to increase stability and roll margin of vehicle by receiving the steering angle as an input and vehicle variables as a feedback signal. The effectiveness of proposed controller and vehicle model were evaluated during fishhook and single lane-change maneuvers. Simulation results demonstrate that in both cases (FLC and LQR controllers) by reducing roll angle, lateral acceleration and side slip angles remain under 0.6g and 4° during maneuver, which ensures vehicle stability and handling properties. Finally, the sensitivity and robustness analysis of developed controller for varying longitudinal speeds were investigated.

“…In addition, an active anti-roll bar (AARB) was applied to control the roll dynamics. Yim and et al [12][13][14][15] employed the integrated chassis control by coordinating the four-wheeled drive (4WD), continuous damping control (CDC) and electronic stability control (ESC) systems to investigate the ROP and the lateral stability. The coordination of the AFS, DYC and active tilt systems is discussed by Goodarzi et al 16 Various vehicle models were used to simulate the roll dynamics in the pre-rollover manoeuvres.…”

This article presents an integrated control of yaw, roll and vertical dynamics based on a semi-active suspension and an electronic stability control with active differential braking system. During extreme manoeuvres, the probability of vehicle rollover is increased and the stability of lateral and yaw vehicle motions is deteriorated because of the saturation of tyre forces. Furthermore, when the road excitation frequencies are equal to the natural frequencies of the unsprung masses, the resonance phenomena occurs, which causes some oscillations getting revealed on responses of the yaw and lateral vehicle dynamics. In these situations, the active braking alone cannot be helpful to improve the vehicle handling and stability, considerably. In order to overcome these difficulties, a coordinated control of the semi-active suspension and the active braking is proposed, using a fuzzy controller and an adaptive sliding mode controller, respectively. A non-linear full vehicle model with 14 degrees of freedom is established and combined with the modified Pacejka tyre model. As the majority of vehicle dynamics variables and the road profile inputs cannot be measured in a cost-efficient way, a non-linear estimator based on unscented Kalman filter is designed to estimate the entire vehicle dynamics states and the road unevenness. Simulation results of the steering manoeuvres on the random road inputs show that the proposed chassis system can effectively improve the vehicle handling, stability and ride comfort.

“…A comprehensive state of the art on Integrated Vehicle Dynamics Control (IVDC) is presented by Yu et al [1]: some methodologies devoted to IVDC are reviewed and some control strategies to coordinate chassis control systems are summarized; the focus is on integration techniques applied to steering and braking. [2] present a method for designing an active roll control system, combined with integrated chassis control for hybrid four-wheel-drive vehicles: weighted pseudoinverse-based control allocation and simulation-based optimization are proposed to distribute the control yaw moment. A combination of active front steering with rear torque vectoring actuators in an integrated controller is investigated by Bianchi et al [3] for vehicle stability and trajectory tracking.…”

This paper deals with improving comfort and handling for a ground vehicle through the coordinated control of different active systems available in passenger cars, e.g., electronic stability control, active roll control and engine torque control. The authors first describe separate control systems, each with its logic, showing advantages and limits, then propose various possible integrations, aiming at exploiting the benefits of a coordinated approach. Finally, the proposed control logics are tested on a vehicle model: simulation results prove the effectiveness of the approach in improving vehicle response during typical handling maneuvers.
