Lateral Stability Control of 4WD Vehicle considering Ride Performance

In order to improve the lateral stability of 4WD vehicle and guarantee its ride performance, this study designs target yaw control system based on sliding mode variable structure control, proposes driving torque distribution control algorithm based on the response of vehicle stable steering characteristic, and designs semiactive suspension control system based on double-fuzzy controller. The control performance is analyzed during the step steering and the split-µ road turning. The results indicate that the combined control system is able to improve the lateral stability of this 4WD vehicle during turning, reduce its body vibration acceleration and suspension dynamic deflection during travelling on bumpy and uneven road, guarantee its dynamic property, and improve its comprehensive performance.
