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.

Abstract: Method for the prevention of turnover of rear wheel steered vehicles, wherein the rear wheels are steered to attain desired steering angles driven with a desired speed in which method actual slip angles are determined which are compared with pre-set slip angles, in order to intervene in a vehicle steering when an actual slip angle is in a predetermined relation to the pre-set slip angle, in which method further only the slip angles of the steered rear wheels of the vehicle are determined and compared with a predetermined slip angle maximum value, and the steering angle being controlled such that the slip angle is below the predetermined maximum value.
