Multi-car elevator system with autonomous car movers configured for collision avoidance

Abstract

Disclosed is ropeless elevator system having: a car mover operationally connected to an elevator car, the car mover configured to move the elevator car along a hoistway lane and to operate autonomously, wherein the car mover has an Autonomous Car Separation Assurance (ACSA) system that has: a sensor configured to provide sensor data representing positional information of the elevator car, a motion control system configured to control motion of the car mover, wherein the ACSA system is configured to estimate an operational state of the elevator car by processing the sensor data and velocity data, representing velocity of the car mover within the hoistway lane, via a State Observe Filter, and wherein the ACSA system is configured to control the car mover to avoid a collision between the elevator car and another object in response to estimating the operational state of the elevator car.
