Elevator horizontal vibrations are actively controlled by retrieving data stored in memory indicative of the out-of-straightness of the elevator car's guide rails. The stored data is compiled during a learning run by summing the car's relative displacement with respect to the rail with a doubly integrated acceleration signal indicative of the car's deviation from true vertical.

Contrôle actif des vibrations horizontales d'un ascenseur par la récupération de données stockées en mémoire servant à indiquer que les rails-guides de la cabine ne sont pas droits. Ces données stockées sont compilées lors d'un trajet d'apprentissage effectué par la cabine, au cours duquel on ajoute le déplacement relatif de la cabine par rapport au rail à un signal d'accélération ayant subi une double intégration qui rend compte de la déviation de la cabine par rapport à la verticale vraie.
