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.
