Vehicle Rollover Warning and Control Based on Attitude Detection and Fuzzy PID

Car rollovers are a class of serious traffic accidents that can easily cause heavy casualties and property damage, particularly for special operation vehicles. To enhance the driving stability vehicles on forest roads, we developed control strategy wire-controlled auxiliary braking based body-attitude detection overall design system. Moreover, system was further investigated developed. A three-degrees-of-freedom (3-DOF) vehicle dynamics model with longitudinal, lateral, lateral tilt actual-vehicle test data. The load-transfer rate (LTR) selected as early warning algorithm rollover; differential realized by adjusting pressure wheel cylinders; automatic speed reduction achieved according to rollover attitude combining fuzzy-PID algorithm. Finally, developed, results verified effectiveness anti-rollover under extreme operating conditions.
