Automatic setting of the parameters of a profile generator for a high performance elevator door system

A method for opening or closing an elevator door, comprising:

• a) providing a requested flight time for said elevator door opening or closing;
• b) providing a requested creep in distance for said elevator door opening or closing;
• c) providing a requested creep out distance for said elevator door opening or closing;
• d) providing a requested creep speed for said elevator door opening or closing;
• e) calculating a requested acceleration distance, for setting the distance that said opening or closing elevator door is in an acceleration or deceleration state, in response to said requested creep speed, requested creep in distance, requested creep out distance, requested flight time, a doorway width, and a constant maximum velocity distance;
• f) providing a maximum elevator door speed, in response to said acceleration distance and a jerk-in/jerk-out time which is proportional to said requested flight time, for dictating a maximum speed said elevator may obtain when opening or closing;
• g) calculating an acceleration, dictated for said elevator door to experience in said acceleration state, in response to said maximum speed and jerk-in/jerk-out time;
• h) providing a jerk, which said elevator door will obtain during said opening or closing, said jerk being provided in response to said acceleration;
• i) providing a constant acceleration time, for which said elevator door is opening or closing at said acceleration in response to said maximum speed and said acceleration;
• j) providing a calculated flight time in response to said requested flight time, said maximum speed and said requested creep speed;
• and
• k) moving said elevator door from a closed or opened state to the alternate state at said requested creep speed for said creep in distance, then moving said elevator door in response to said jerk and acceleration for approximately said acceleration distance and time, then decelerating said elevator door at a rate proportional to said acceleration and jerk for approximately said acceleration distance and time, then moving said elevator door at said requested creep speed for said creep out distance, the total time for said elevator door movement being equal to said calculated flight time.
