Abstract

Le système de direction, avec moteur électrique d'assistance (8), comprend des moyens de traitement (17) qui pilotent ce moteur, en déterminant un signal de pilotage (S3) en fonction d'un signal de commande (S1) déterminé à partir de la mesure (11) du couple exercé par le conducteur (13) sur le volant (2) en appliquant un gain dépendant de la vitesse longitudinale du véhicule, et en fonction d'un signal de compensation (S2) déterminé à partir de la mesure (11) du couple exercé par le conducteur (13) sur le volant (2), et d'un consigne de correction déterminée en fonction d'au moins un parmi : un paramètre caractéristique du glissement de chaque roue reliée à la direction, un paramètre caractéristique de la dynamique longitudinale du véhicule, un paramètre caractéristique de la dynamique latérale du véhicule. Ainsi, le système de direction compense l'effet de fortes accélérations des roues sur le ressenti au volant.The steering system, with electric assistance motor (8), comprises processing means (17) which control this motor, determining a control signal (S3) as a function of a control signal (S1) determined at from the measurement (11) of the torque exerted by the driver (13) on the steering wheel (2) by applying a gain depending on the longitudinal speed of the vehicle, and as a function of a compensation signal (S2) determined from the measurement (11) of the torque exerted by the driver (13) on the steering wheel (2), and of a correction setpoint determined as a function of at least one of: a parameter characteristic of the slip of each wheel connected to the steering , a parameter characteristic of the longitudinal dynamics of the vehicle, a parameter characteristic of the lateral dynamics of the vehicle. Thus, the steering system compensates for the effect of strong wheel acceleration on the feel of the wheel.
