Abstract

A method for determining a degraded guide rail condition in an elevator system, a computer program product, and an elevator system are disclosed. The method includes obtaining first data including information about movement of an elevator component relative to a guide rail, and obtaining second data including information about movement of an elevator component. The method further includes comparing the first data and the second data to each other, and detecting, based on the comparison, a deviation fulfilling a deviation criterion. Still further, the method includes creating a signal indicating the degraded, such as misaligned, guide rail condition, such as of the first or the second guide rail.
