Control apparatus and method for motor vehicle parking system
First Claim
1. A control apparatus for a motor vehicle parking system having a plurality of laterally moving pallets located on a ground-level floor, a plurality of lifting pallets located on an upper level column and whose number is at least one more than the number of the laterally moving pallets, a driving unit installed on each of the pallets supplying a driving force to move the pallets, and a control unit controlling the driving unit, the control apparatus comprising:
- a parking state backup unit storing both data indicating the identification of the lifting pallet called by the control unit during automatic parking operation and data indicating the operation status of the pallets caused by an operation of the lifting pallet; and
an automatic parking resuming unit resuming the automatic parking operation by detecting the data indicating a current parking state of the system when power is recovered after a failure by comparing between the data stored in the parking state backup unit and data indicating the current parking state.

Abstract
A control apparatus and method for motor vehicle parking system capable of resuming an automatic parking operation when a power failure is recovered by the backup of the previous operation status data required for the automatic parking operation, thereby reducing the time spent in a stand-by condition for storing or retrieving a motor vehicle. The control apparatus for the parking system includes a plurality of vertically and laterally moving pallets, a driving section for driving the pallets, and a control section. The control section includes a manipulation section for selecting a pallet number, an operation status detector for detecting the operation status of the pallets, a controller having first and second memories for storing the pallet number data from the manipulation section, and the pallet operation status data from the operation status detector and for outputting drive signals for driving the vertically and laterally moving pallets so that a vertically moving pallet moves up or down without collision with the laterally moving pallets, a DC power supply for supplying to the controller a DC power and a backup battery for supplying a backup power to the controller when a normal power supply is cut off.

3. A control apparatus for a motor vehicle parking system having a plurality of laterally moving pallets located on a ground-level floor, a plurality of lifting pallets located on an upper level column and whose number is at least one more than the number of the laterally moving pallets, and a driving unit installed on each of the pallets for supplying a driving force to shift move pallets, the control apparatus comprising:
-
a manipulation unit having a pallet number selection unit selecting the number of the lifting pallet to be called for storage or retrieval, and outputting a corresponding pallet number signal when the pallet number is selected by the pallet number selection unit; operation status detecting unit installed on the lifting pallets and on the laterally moving pallets detecting the operation status of the pallets to output a detected operation status signal; a control unit storing pallet number data defined by the pallet number signal inputted from the manipulation unit and storing pallet operation status data defined by the pallet operation status signal inputted from the operation status detecting unit, the control unit outputting both a first drive signal driving the lifting pallet corresponding to the pallet number signal to move the lifting pallets up or down and a second drive signal driving the laterally moving pallets to provide a space for the lifting pallet to move down without a collision with the laterally moving pallets to the driving unit of the lifting pallet assigned by the pallet number signal and to the driving unit of the laterally moving pallets;
respectively, said control unit controlling automatic resumption of a parking operation after recovering from a power failure;a direct current power supply unit supplying to the control unit a direct current power source; and a backup battery unit connected to the normal alternating current power source recharging with the direct current power source converted from the alternating current power source during normal operation and supplying a backup power source to the control means when the power failure occurs. - View Dependent Claims (4, 5)

6. A control method for a motor vehicle parking system having a plurality of laterally moving pallets located on a ground-level floor and a plurality of lifting pallets located on an upper level column, the control method comprising:
-
(a) storing a parking state including a pallet identifier of the called pallet and an operation status of the called pallet; and (b) automatically resuming a parking operation if the condition meets the requirement to resume the automatic parking operation as a result of comparing the stored parking state with a current parking state of the system when power is restored after a failure. - View Dependent Claims (7, 8, 9, 10, 11)

12. An automatic parking resumption apparatus for a motor vehicle parking system, comprising:
-
a parking state backup unit storing parking state of an automatic parking operation, said parking state including a pallet identifier of a pallet and an operation status of the pallet; and an automatic operation detecting unit determining if parking operation can be automatically resumed, when power is restored after a failure, by comparing a current parking state of said parking system and said parking state of said automatic parking operation stored in said parking state backup unit. - View Dependent Claims (13)

14. An automatic motor vehicle parking system, comprising:
-
a plurality of laterally moving pallets; a plurality of vertically moving pallets; and a control unit controlling a parking operation including controlling said pluralities of laterally and vertically moving pallets, said control unit storing a parking state including a pallet identifier and an operation state of a pallet as operations are carried out, said control unit automatically resuming said parking operation, when power is restored after a failure, if said control unit determines that said parking operation can be resumed by comparing a current parking state of the parking system to said stored parking state of said parking operation. - View Dependent Claims (15, 16)
