Abstract

See full text

Embodiments are directed to reducing at least one dynamically generated error in terms of an actual position of an elevator car, comprising: triggering an inertial measurement unit (IMU) to compute a position of an elevator car of an elevator system, obtaining a position of a correcting vane in a hoist-way of the elevator system, obtaining a position of the elevator car as determined by an encoder of the elevator system, and estimating the position of the elevator car based on the computation of the position by the IMU, the position of the correcting vane, and the position of the elevator car as determined by the encoder.
