Abstract
A method for the prevention of turnover of rear wheel steered vehicles includes providing a vehicle with a plurality of sensors, and providing slip angle restriction software adapted to receive as inputs the outputs of the plurality of sensors. The software calculates an estimated sideslip angle based on sensor outputs, calculates a slip angle on the rear wheels based on the estimated sideslip angle, calculates a maximum allowable slip angle, compares the slip angle and the maximum allowable slip angle, and determines a steering angle correction value if the actual slip angle is greater than the maximum allowable slip angle. Any steering angle correction value calculated is applied to the rear wheels of the vehicle.
