Abstract: A multi-car ropeless elevator system includes at least one lane. An elevator car is arranged in the at least one lane. A linear motor system includes a plurality of stationary motor primary sections extending along the at least one lane and at least one moveable motor secondary section mounted to the elevator car. A plurality of sensors is operatively connected to the linear motor system. Each of the plurality of sensors is operatively associated with a corresponding one of the plurality of stationary motor primary sections. A sensor failure detection and fusion system is operatively connected to each of the plurality of sensors. The sensor failure detection and fusion system operates to identify failures in one or more of the plurality of sensors and fuse data received from remaining ones of the plurality of sensors.

Abstract: An elevator car separation assurance system and method of operation includes determining a position and velocity of each one of a plurality of cars by a safety motion state estimator. A safety assurance module of the system is configured to determine a separation map associated with a first car and an adjacent second car of the plurality of cars. The system is further configured to initiate a first separation assurance-induced event associated with at least one of the first and the second cars and based on the separation map. A recovery manager of the system is configured to detect the first separation assurance-induced event, and upon detection, slow at least a third car of the plurality of cars down.

Abstract: An elevator car is constructed and arranged to move along a hoistway. The car includes a cab support from below by a platform. A vertical member is connected to the platform via a flex joint and extends upward from platform for further elevator cab support. The flex joint facilitates cab isolation from vibration and noise.

Abstract: According to an aspect, an elevator system includes a propulsion system having a plurality of motor segments forming a primary portion and a plurality of drives to impart force on a secondary portion coupled to an elevator car. The elevator system also includes a controller operable to identify a local neighborhood of the drives and determine a health status of each of the drives within the local neighborhood. The controller is further operable to adjust a thrust command per active drive of the local neighborhood based on at least one of the health status and a position of each active drive of the local neighborhood with respect to the secondary portion.
