Elevator control system and method for controlling elevator

An elevator control system, comprising:

• a position detector which detects a present position of a car in a run direction;
• a point-of-origin detector which detects passage of the car at a point-of-origin position which is separated by a distance set in advance from a landing position of the car;
• a plurality of pattern generators, each of which generates, based on mutually different algorithms, a run pattern from the point-of-origin position to the landing position in which acceleration is continuous from before the car passes the point-of-origin position until the car stops;
• a run controller which causes a run of the car to follow a run pattern generated by any of the plurality of pattern generators based on a present position of the car which is detected by the position detector;
• and
• a pattern selector which selects a run pattern that minimizes a landing time required by a run from the point-of-origin position to the landing position as the run pattern which the run controller causes the run of the car to follow from among the run patterns respectively generated by the plurality of pattern generating units based on a speed of the car at a timing when the point-of-origin detector detects a passage of the car.

A method for controlling an elevator, comprising:

• detecting passage of a car at a point-of-origin position which is separated by a distance set in advance from a landing position of the car;
• acquiring the speed of the car at a timing when the passage of the point-of-origin position by the car is detected;
• selecting a run pattern which minimizes a landing time required by a run from the point-of-origin position to the landing position based on the acquired speed of the car from a plurality of run patterns based on mutually different algorithms from the point-of-origin position to the landing position in which acceleration is continuous from before the car passes the point-of-origin position until the car stops;
• and
• causing a run of the car to follow the selected run pattern based on a present position of the car.
