Abstract

L'invention concerne un système d'ascenseur comprenant une cabine, qui est disposée dans une cage de manière mobile en direction horizontale le long d'un rail. Une unité d'entraînement, p. ex. un entraînement linéaire (ou entraînement à moteur linéaire) est réalisée pour déplacer la cabine le long du rail. Une unité de freinage est réalisée pour freiner la cabine. Le système d'ascenseur comprend en outre une unité de commande qui est réalisée pour, dans le cas d'un changement de vitesse imminent de la cabine, initier en premier une accélération B2 sur une personne se trouvant dans la cabine et pour ensuite commander l'unité de freinage ou l'unité d'entraînement de telle façon que celles-ci transmettent le changement de vitesse au moyen d'une accélération B1 sur la cabine, l'accélération B2 étant supérieure en valeur absolue à l'accélération B1. L'accélération B2, qui agit sur la personne dans la cabine, est avantageusement une impulsion, c'est-à-dire un changement de vitesse de courte durée mais de forte intensité.
