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.
