Abstract

A stairlift and a method of operating the same. The stairlift includes a stairlift rail, a carriage mounted on the rail, a chair pivotally mounted on the carriage, at least one motion sensor, a chair levelling motor operable to pivot the chair relative to the carriage as the carriage traverses the rail, memory, and a control system. The control system is operable to store a record of an undesirable movement of the chair. The record includes an indication of the position along the rail at which the undesirable movement occurred. The control system is also operable, during a subsequent traversal of the rail by the carriage, to apply a remedy to attempt to prevent a reoccurrence of the undesirable movement of the chair at the position indicated in the record, The control system is further operable to determine whether the undesirable movement of the chair reoccurred.
