Abstract: An elevator control system is configured to control an elevator car constructed and arranged to move along a hoistway defined by a stationary structure. The elevator system may include a communication pathway and a hoistway control system supported by the stationary structure and configured to send a continuous brake command signal over the pathway. A car control system is carried by the elevator car and is configured to receive the continuous brake command signal and initiate a brake Ustop mode upon a loss of the brake command signal, and independent of the hoistway control system.

Abstract: An elevator system with an elevator car 14, a linear propulsion system to impart force to the elevator car in a hoistway 11, a hoistway communication network 106, 206, a local communication network 110, 210, 310 and motion controls. One of the motion controls proximate to the elevator car is designated as a primary control 61 operable to command at least one drive 42A-42F via the local communication network. The at least one drive is coupled to one or more motor segments 22 of the linear propulsion system. The elevator system further includes a controller 46 operable to command the primary control via the hoistway communication network to reposition the elevator car within the hoistway. The designation of the primary control transitions between the motion controls as the elevator car moves in the hoistway.

Abstract: An elevator car travels in a lane (113, 115, 117) of an elevator shaft (111). A linear propulsion system imparts force to the car (214). The system includes a first part (116) mounted in the lane of the shaft and a second part (118) mounted to the elevator car configured to co-act with the first part to impart movement to the car. Car state sensors (360a-c) are disposed in the lane and determine a state space vector of the car within the lane. A sensed element (364) on the car is sensed by the plurality of car state sensors when the car is in proximity to the respective car state sensor. A control system (225) applies an electrical current to at least one of the first part and the second part and the plurality of car state sensors communicate with the control system and the linear propulsion system to provide state space vector data.
