Title (EN) METHOD FOR THE CONTROL OF VEHICLE STEERING
(FR) PROCÉDÉ PERMETTANT DE COMMANDER LA DIRECTION D'UN VÉHICULE
Abstract:
(EN) The present invention relates to a method for controlling a feedback torque actuator (130) in a steering system (100), comprising said feedback torque actuator and an assistance actuator (140), incorporating the following method steps for the feedback torque control: - measurement of at least one input signal with the aid of a sensor, - determination of a steering angle from the above-mentioned input signal, - transformation of the above-mentioned input signal of a steering angle to a target steering-wheel torque, and - control of the mentioned feedback torque actuator via a closed loop current control to achieve said target steering-wheel torque, and according to the invention, the above-mentioned assistance actuator is given a very high gain resulting in the fact that the torque in the axle above this assistance actuator is so low that the steering-wheel torque will be close to the above-mentioned target steering-wheel torque whereby acceptable steering feel is achieved.
(FR) La présente invention concerne un procédé permettant de commander un actionneur de couple de rétroaction (130) dans un système de direction (100), comprenant ledit actionneur de couple de rétroaction et un actionneur d'assistance (140), comprenant les étapes de procédé suivantes permettant de commander le couple de rétroaction : - la mesure d'au moins un signal d'entrée à l'aide d'un capteur, - la détermination d'un angle de braquage à partir du signal d'entrée susmentionné, - la conversion du signal d'entrée d'angle de braquage susmentionné en un couple au volant cible, et - la commande de l'actionneur de couple de rétroaction susmentionné par l'intermédiaire d'une commande de courant en boucle fermée pour obtenir ledit couple au volant cible, et selon l'invention, l'actionneur d'assistance susmentionné reçoit un gain très élevé de sorte que le couple de l'axe situé au-dessus de cet actionneur d'assistance est si faible que le couple au volant sera proche du couple au volant cible susmentionné, ce qui permet d'obtenir une sensibilité au braquage acceptable.
