VEHICLE STABILITY ENHANCEMENT BY SIMULTANEOUS TRACTION AND BRAKING CONTROL IN VEHICLES UTILIZING ACTIVE DIFFERENTIALS

摘要：

This paper investigates the improvement of the vehicle dynamics performance by the use of a rear limited slip differential.A front arrti lock braking system will support active differential in generating yaw moment, if necessaryan optimal linear quadratic regulator (LQR) controller is employed together with an elaborate six-degree-of-freedom (DOF) linear vehicle model.Simulation results by 9DOF nonlinear vehicle model and magic formula in different maneuvers and road conditions shows the capability of designed robust integrated controller in keeping stability in various conditions especially at cornering situations while accelerating, at which the other control methods based on braking decelerate the vehicle not in favour of the drivers desires.
