Patent ID: 7558657

Claim:
A method for the prevention of turnover of rear wheel steered vehicles, the method comprising: providing a vehicle with a plurality of sensors, the plurality of sensors comprising a steering angle sensor, driving speed sensor, a yawing rate sensor, wherein each of the plurality of sensors has at least one output; providing slip angle restriction software in the vehicle, the software adapted to receive as inputs the outputs of the plurality of sensors, the software adapted for calculating an estimated sideslip angle based on the outputs of the plurality of sensors; calculating a slip angle on the rear wheels based on the estimated sideslip angle; calculating a maximum allowable slip angle; comparing the slip angle and the maximum allowable slip angle; and determining a steering angle correction value if the actual slip angle is greater than the maximum allowable slip angle; and applying the steering angle correction value to the rear wheels of the vehicle if the actual slip angle is greater than the maximum allowable slip angle.
