Abstract: A control system for controlling the motion of a hydraulic elevator calculates a deceleration distance based upon the elevator velocity and begins the deceleration phase of the elevator motion upon the elevator reaching the calculated distance from the landing. In a particular embodiment, the control system includes a hydraulic valve (38), a space encoder (16), and a controller (42). The space encoder (16) produces velocity and position measurements. The controller (42) uses the velocity inputs to determine the deceleration distance and, upon the elevator car (14) reaching the calculated distance from the landing as measured by the position inputs from the space encoder (16), commands the hydraulic valve (38) to actuate and begin the deceleration phase. In an alternate embodiment, an interface unit (56) connected between the controller (43) and the hydraulic valve (38) calculates a delay between the deceleration command based upon a predetermined distance and the calculated deceleration distance based upon car velocity. Upon expiration of the delay, the interface unit (56) commands the hydraulic valve (38) to actuate and begins the deceleration phase.

Abstract: A transition valve for a hydraulic elevator includes a block, a spool, an actuator, and an end cap. The actuator may be either a solenoid type actuator or an electric motor type actuator. The end cap includes an opening permitting engagement between the actuator and the spool. In a particular embodiment, the actuator is an electric motor engaged with the spool via a crank and arm. This arrangement translates the rotational motion of the motor into linear motion of the spool with a sine curve profile.

Abstract: An elevator system is provided that includes an elevator car, a counterweight, a load bearing flexible member, a motor having a drive, and an elevator control system. The car and counterweight are operable to be translated within a hoistway. The load bearing flexible member extends between the elevator car and the counterweight. The motor is operable to move the load bearing member and thereby drive the elevator car and counterweight within the hoistway. The elevator motor and drive are configured to selectively produce regenerative power. The elevator control system includes a power manager unit and a power storage device. The power storage device includes a supercapacitor unit and a battery unit. The power manager unit is operable to selectively manage the flow of power between the power storage device and the motor drive, and the flow of regenerative power from the motor drive to the power storage device.
