An elevator system includes a microprocessor-based cab controller mounted directly on an elevator car, which controls the operation of the elevator door. Elevator door motion is commanded in response to the difference in actual door velocity from a desired, dictated door velocity in accordance with desired rates of acceleration and deceleration, maximum velocity, acceleration and deceleration, the point at which deceleration is to begin, and a velocity at which deceleration is to decrease. The disclosed invention provides selective modification in maximum velocity along with the point at which deceleration is to begin, the velocity at which deceleration is to decrease along with the point at which deceleration is to begin, and/or simply the point where deceleration is to begin, so that door velocity profiles may be tailored to suit any particular door of a given type. An exemplary environment for and details of the present invention are disclosed. |
