A vehicle lift has a communication and/or a lift control assembly, including a processor, which is functional to control the raising and lowering of the lift and to enable the display of, and communication of, a variety of lift data. The vehicle lift includes sensors in communication with the control, where the pre-programmed processor recognizes and categorizes lift data and lift faults before sending warnings, notices, and other lift data to lift users, maintenance providers, or a central headquarters. The visual display unit of the assemblies may include a processor and may be detachable or adjustable.

Electronically controlled vehicle lift and vehicle service system

A vehicle lift has an electronic control which is functional to control the raising and lowering of the lift and to enable the display of a variety of information regarding the operation of the lift. The electronic control includes control logic which generates an operation fault indication signal based on the application of predetermined criteria to operation conditions, with concomitant display of data indicative of the operation fault indication signal accompanied by inhibiting or altering raising or lowering of the lift. The electronic control also includes maintenance control logic which generates a maintenance condition indication signal to enable generation of maintenance notice data. A vehicle service system includes a network placing controls of such vehicle lifts in communication with each other or a central computer processor.

A vehicle lift control maintains multiple points of a lift system within the same horizontal plane during vertical movement of the lift engagement structure by synchronizing the movement thereof. A vertical trajectory is compared to actual positions to generate a raise signal. A position synchronization circuit synchronizes the vertical actuation of the moveable lift components by determining a proportional-integral error signal.
