Parking Assist Candidate Display Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking assist systems face challenges in allowing occupants to easily select their desired parking position without overwhelming processing loads and complicating the selection operation, as they can only set parking spaces within a predetermined region as targets.
Innovation Solution
A parking assist system that includes a parking position candidate detector to identify available parking spaces, a display device to show these candidates, and a control device to manage the display and autonomously move the vehicle to the selected position, with features like prioritizing display based on proximity and type of parking space, and limiting the number of candidates to prevent overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all detected parking position candidates are displayed on the display device, then the occupant can select from more parking options, but the processing load increases and the selection operation becomes complicated
Solution Approach 1:
The parking position candidates are segmented into multiple pages, with each page displaying a limited number of candidates (e.g., 3-5 positions). The control device divides the full set of detected candidates into manageable groups, allowing the occupant to navigate through pages rather than being overwhelmed by all options at once. This segmentation maintains selection flexibility while reducing the cognitive and operational burden on the occupant.
Solution Approach 2:
The display device dynamically adjusts the number of parking position candidates shown based on the current page and occupancy input. The control device responds to occupant inputs (such as directional controls or scrolling gestures) to dynamically change the displayed set of candidates, transitioning between pages as needed. This dynamic presentation maintains versatility while managing complexity through adaptive information display.
2Ease of operation
If the parking assist system allows selection of any parking position around the vehicle, then the occupant can choose their desired position, but the selection operation becomes complicated
Solution Approach 1:
The control device segments the parking position candidates into logical groups or pages, presenting only a subset of candidates at any given time. This segmentation approach allows the occupant to easily select from a manageable number of options displayed on the screen, while still providing access to all detected parking positions through page navigation. The segmentation reduces selection operation complexity while maintaining the ability to choose any desired position.
3Adaptability or versatility
If a large number of parking position candidates are displayed, then more parking options are available, but the processing load becomes excessive
Solution Approach 1:
The control device segments the display of parking position candidates into multiple pages, with each page containing a limited number of candidates. This segmentation reduces the processing load for each display update, as the control device only needs to manage and render a small subset of candidates at any given time, rather than handling all candidates simultaneously. The full set of parking options remains available through page navigation.
Solution Approach 2:
The control device performs partial action by displaying only a portion of the detected parking position candidates at any given time, rather than all candidates. This partial display approach reduces the processing load and energy consumption associated with rendering and managing the complete set of candidates, while still providing sufficient parking options through multi-page navigation. The system processes and stores all candidates but selectively displays subsets to manage computational resources efficiently.

AI summary
A parking assist system includes a control device configured to control screen display of a display device, to set a parking position candidate selected by an occupant as a target parking position, and to control an autonomous parking operation to autonomously move the vehicle to the target parking position. When a number of the parking position candidates detected by a parking position candidate detector exceeds a predetermined upper limit number, the control device selects, from among the detected parking position candidates, the upper limit number of parking position candidates to be displayed on the display device according to a predetermined rule and causes the display device to display the parking position candidates that have been selected.
