Vehicle yaw stability control and its integration with roll stability control

The paper presents a vehicle yaw stability control (YSC) strategy devoted to prevent vehicles from spinning and drifting out. With yaw stability control system, counter braking was applied at individual wheels as needed until steering control and vehicle stability were regained. However, YSC system may not react properly to, or even deteriorate many on-road rollover events. An integration control system, vehicle dynamics control system (VDC), including yaw stability control and roll stability control was presented and discussed. With this improved control system, the vehicle can afford nice manoeuvrability and stability.
