Patent attributes
A method for operating an elevator control system for controlling and monitoring the movements of at least one elevator car when the elevator car approaches individual floors in a building, and in the process stops at a respective floor in a prescribed stopping position, the method including, in conjunction with a floor stop, determining an overall error in the form of a deviation between an actual position of the elevator car and a position of the elevator car assumed as the current position. The elevator control system generates service signals based on a statistical acquisition of several values for the overall error, and/or wherein the overall error is used to ascertain a derivative value, which is taken into account along with the current or stopping position during a comparison between the current position and stopping position performed by the elevator control system for approaching the respective stopping position.
