Abstract

Direction assistée comprenant des moyens de commande sensibles au couple exercé sur le volant et des moyens moteurs d'assistance dont la mise en action est commandée par les moyens sensibles au couple lorsque ce couple devient egal ou supérieur à un seuil déterminé. Elle comprend un dispositif G propre à interdire toute mise en action des moyens moteurs d'assistance 2 lorsque le véhicule est soumis à une accélération latérale égale ou supérieure à une valeur déterminée correspondant au roulage du véhicule dans une courbe et à une vitesse telles qu'elles imposent un couple de braquage au volant inférieur au susdit seuil. Application aux véhicules automobiles.Power-assisted steering comprising control means sensitive to the torque exerted on the steering wheel and motor assistance means, the actuation of which is controlled by the means sensitive to the torque when this torque becomes equal to or greater than a determined threshold. It comprises a device G suitable for preventing any actuation of the motor assistance means 2 when the vehicle is subjected to a lateral acceleration equal to or greater than a determined value corresponding to the rolling of the vehicle in a curve and at a speed such that they impose a steering torque on the steering wheel lower than the aforesaid threshold. Application to motor vehicles.
