Abstract:
1. A method to control a steering system ( 4 ) for a road vehicle ( 1 ), which steering system ( 4 ) adjusts the steering angle of the front wheels ( 2 ) of the road vehicle ( 1 ) by means of a steering wheel ( 6 ); the steering system ( 4 ) comprises: the steering wheel ( a steering rod ( a transmission device ( a servomechanism ( the control method comprises the following steps: determining, in a preliminary step of design and optimization, an actual transmission error (εT choosing, in the preliminary step of design and optimization, a target transmission error (εT measuring the current angular position of the steering wheel ( calculating, for each angular position of the steering wheel ( determining a variation (ΔF) on the intensity of the servoassistance force applied by the servo mechanism (
