A motion of a first car and a second car in a multi-car elevator system, wherein the first car and the second car move independently in an elevator shaft, is controlled by generating a command to move the first car according to a first deceleration curve, if a relationship between a position and a velocity of the first car corresponds to a value on the first deceleration curve; and by generating a command to move the second car according to a second deceleration curve, if a relationship between position and a velocity of the second car corresponds to a value on the second deceleration curve, wherein a distance between the first and the second deceleration curve is equals or greater than a minimum distance. |
