a method is aimed at controlling a steer - by - wire steering system of a vehicle having at least one steering axle having at least two steer wheels electronically controlled by a control member . in the case of asymmetric adhesion conditions , the method anticipates steering into the skid for the first steer wheel that is on the surface exhibiting the higher coefficient of adhesion — for example asphalt — so as to counter a moment applied to the z - axis . at the same time , the second steer wheel which is on the surface having the lower coefficient of adhesion — for example a sheet of black ice — remains in the vehicle direction of travel or is oriented towards the second steer wheel in a snow plough mode . the vehicle stability is vastly improved when the vehicle regains an area of uniform adhesion .
