Patent number: 10654683Abstract: An elevator system (100) includes an elevator car (102) that is configured to travel along a guide rail (104), and a braking assembly (116) coupled to the elevator car (102). The braking assembly (116) is configured to selectively operate in a disengagement mode that allows the elevator car (102) to travel along the guide rail (104), and an engagement mode that inhibits the elevator car (102) from traveling along the guide rail (104). The electronic braking assembly controller (128) is in signal communication with the braking assembly (116) and is configured to generate an electronic braking signal that activates the engagement mode of the braking assembly (116). When the engagement mode is activated, the elevator car (102) decelerates without exceeding a predetermined g-force (g) threshold regardless as to whether a load applied to the elevator car (102) changes such that the elevator car (102) is stopped at a floor landing (106).Type: GrantFiled: July 1, 2015Date of Patent: May 19, 2020Assignee: OTIS ELEVATOR COMPANYInventors: Franck Dominguez, Frederic Beauchaud, Nicolas Guillot, Pascal Rebillard
