Publication number: 20240116736Abstract: A position measuring unit detects a present position of a car. A point-of-origin detecting unit detects a 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. Each of pattern generating units generates a run pattern based on mutually different algorithms. In each run pattern, an acceleration from before the car passes the point-of-origin position until the car stops is continuous. A pattern selecting unit selects a run pattern which minimizes a landing time as a run pattern which a run control unit causes a run of the car to follow based on a present position. The pattern selecting unit makes the selection based on a speed of the car at a timing when the car passes the point-of-origin position.Type: ApplicationFiled: April 12, 2021Publication date: April 11, 2024Applicant: Mitsubishi Electric CorporationInventors: Eiji YOKOYAMA, Hidetaka ISHIGURO, Hiroyuki ENOKIJIMA
