Abstract
An illustrative example elevator system includes an elevator car, a machine that selectively causes movement of the elevator car, and a drive that controls the machine to control movement of the elevator car at an intended elevator car speed. The drive is configured to use information regarding operation of the machine to determine whether an abnormal passenger behavior (APB) condition exists that affects movement of the elevator car. The drive is configured to alter the elevator car speed when the APB condition exists.
