ABSTRACT OF THE DISCLOSURE A hydraulic elevator system includes a hydraulic jack for raising and lowering the car and a distributed intelligence microprocessor control system, containing a number of subsystems, each having designated control respon- sibilities. A door operator microprocessor subsystem initi- ates stored open and close cycles responsive to external commands. A selector microprocessor subsystem determines target floor and distance values, produces slowdown interrupt signals when the car nears a target floor, and produces levelling signals for stopping the car at a landing. A car logic controller includes a microprocessor for issuing run commands to a relay-based power controller, issuing door open and door closed commands to the door operator microprocessor, issuing run signals to the selector microprocessor, and con- trolling elevator slowdown. A serial communications link is provided among the various microprocessors in the system.
