Deceleration time for an elevator car

摘要

A method of adjusting an elevator speed comprising the steps of determining a desired creep period (tcreep), determining an actual creep period (tactual-creep), determining a difference between the desired creep period and the actual creep period, determining a deceleration time (Tdec) for minimizing the difference between the desired creep period and the actual creep period, and adjusting the elevator speed in response to the deceleration time.
