Abstract:
A method of operating an elevator installation and the elevator installation include elevator doors actuated by an elevator drive according to a travel curve. At least one sensor unit detects pressure relationships and/or air flows. An evaluating unit determines a travel curve, which is optimal with respect to the detected pressure relationships and/or air flows, from a plurality of travel curves.
