A method for controlling a steering system having an electric assistance motor in view of reducing shocks against end-of-travel stop, the method including getting a distance information of the rack with respect to the end of travel stop, getting an actual rotation speed information of the steering wheel, identifying a maximum allowed acceleration for the steering wheel, the maximum allowed acceleration being such that, in view of the distance information and the actual rotation speed information, the rotation speed of the steering wheel can decrease pursuant to a target deceleration value of a target deceleration profile so as to be lower than a required maximal speed when arriving at the end-of-travel stop, determining a maximum power assistance torque from the maximum allowed acceleration for controlling the power assistance torque applied to the assistance motor so as to target the deceleration value or profile of the rotation of the steering wheel.
