Automatic Parking Route Data Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automatic parking systems, long travel routes result in large data sizes for route information transmission, increasing the time required to start automatic parking control due to longer download times.
Innovation Solution
An automatic parking management apparatus that transmits a common route, shared among multiple vehicle paths, before determining the specific travel route, and then transmits the non-common route after the travel route is determined, reducing the overall data transmission time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the complete travel route information is transmitted to the vehicle before automatic parking starts, then the vehicle has full route guidance, but the transmission time becomes excessively long when the route is long
Solution Approach 1:
The travel route information is segmented into two parts: common route information (shared among multiple vehicles) and non-common route information (specific to each vehicle's destination). The common route information is transmitted first to reduce initial transmission time, while the non-common route information is transmitted later or on-demand, thus resolving the contradiction between information completeness and transmission time.
Solution Approach 2:
The system performs preliminary transmission of common route information that is shared among multiple vehicles before the vehicle actually needs the complete route data. This allows the vehicle to start with partial route information already loaded, reducing the critical transmission time for destination-specific route details.
2Quantity of substance
If the system waits until the travel route is determined to transmit route information, then the transmission data size is optimized, but the time to start automatic parking increases
Solution Approach 1:
Route information is divided into common route segments (transmitted early with larger data size) and non-common route segments (transmitted later with smaller data size). This segmentation allows the system to prioritize transmission timing over strict data size optimization, reducing startup time while maintaining efficient data usage.
Solution Approach 2:
The system transmits common route information in advance before the vehicle's specific destination is confirmed. This preliminary action accepts larger initial data transmission in exchange for reducing the critical path time for starting automatic parking, as the vehicle can begin preparation with partial route information already available.
3Loss of information
If route information is transmitted in full before vehicle positioning, then the vehicle has complete navigation data, but pick-up/drop-off places become congested due to simultaneous vehicle arrivals
Solution Approach 1:
The system transmits common route information to vehicles in advance before they arrive at the pick-up/drop-off places. This allows vehicles to be staged or held in waiting areas with navigation data already loaded, enabling sequential processing rather than simultaneous arrival and data reception, thus reducing congestion at critical locations.
Solution Approach 2:
By segmenting route information transmission into common (early) and non-common (later) portions, the system enables vehicles to receive essential navigation data before arriving at congested areas, allowing for better traffic flow management and reduced simultaneous arrivals at pick-up/drop-off places.

AI summary
An automatic parking management apparatus is configured to manage an automatic parking control of automatically parking a vehicle in an empty parking space. The automatic parking management apparatus is provided with: an acquirer configured to obtain a common route, which is a common part of a plurality of routes on which the vehicle, which is about to start the automatic parking control, possibly travels in the automatic parking control; a first transmitter configured to transmit information associated with the common route to the vehicle, before a travel route on which the vehicle travels in the automatic parking control is determined; and a second transmitter configured to transmit information associated with a non-common route, which excludes the common route from the travel route, to the vehicle, after the travel route on which the vehicle travels in the automatic parking control is determined.
