Abstract
A method to control a road vehicle with rear steering wheels and having, while driving along a curve, the steps of: determining a desired steering angle for the rear wheels; comparing the desired steering angle with a threshold value; applying, while driving along a curve and if the desired steering angle is greater than the threshold value, to both rear wheels a same actual steering angle that is equal to the desired steering angle; and applying, while driving along a curve and if the desired steering angle is smaller than the threshold value, to a rear wheel on the outside of the curve an actual steering angle greater than the desired steering angle and applying to a rear wheel on the inside of the curve a zero actual steering angle.
