摘要：Improving rollover and stability of the vehicles is the indispensable part of automotive research to prevent vehicle rollover and *** 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 *** 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 *** effectiveness of proposed controller and vehicle model were evaluated during fishhook and single lane-change *** 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 ***,the sensitivity and robustness analysis of developed controller for varying longitudinal speeds were investigated.
