Abstract

Système de modification des caractéristiques aérodynamiques d'un véhicule automobile comprenant au moins un volet (100) définissant une surface interne et une surface externe du volet, le volet (100) étant configuré pour augmenter la déportance du véhicule, en étant mobile entre au moins une position repliée dans laquelle la surface interne du volet est posée contre un bord de fuite de la surface extérieure du véhicule et une position déployée en fonction d'une pression d'air sur la surface externe du volet, caractérisé en ce que le système comprend un moyen de contrôle actif (110) pour permettre ou bloquer un passage entre la position repliée et la position dépliée en fonction d'une information instantanée (120) relative à la dynamique du véhicule.A system for modifying the aerodynamic characteristics of a motor vehicle comprising at least one flap (100) defining an inner surface and an outer surface of the flap, the flap (100) being configured to increase the vehicle's offset, being movable between at least a folded position in which the inner surface of the flap is placed against a trailing edge of the outer surface of the vehicle and an extended position as a function of air pressure on the outer surface of the flap, characterized in that the system comprises active control means (110) for enabling or blocking a passage between the folded position and the unfolded position as a function of instantaneous information (120) relating to the dynamics of the vehicle.
