Dynamic Map Centering for Vehicle Fleet Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display technologies cannot easily allow users to select and focus on specific vehicles among multiple vehicles on a map image, as the display order is fixed, making it difficult to find and manage desired vehicle information.
Innovation Solution
A display control device and method that acquires location and status information of vehicles, allows users to set display conditions, and positions the icon of a vehicle satisfying the conditions at the center of the map image, along with its corresponding location, enabling easy identification of desired vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed sequential order is used to display vehicles at the center of the map image, then the display process is simple and automatic, but the user cannot easily find and focus on specific vehicles of interest
Solution Approach 1:
The display control device dynamically changes the center position of the map image based on user selections. Instead of a fixed sequential display order, the system allows the user to select any vehicle from a list, and the map automatically repositions to center that vehicle. This dynamic adaptation resolves the contradiction by making the display flexible and user-driven while keeping the underlying mechanism simple.
Solution Approach 2:
A vehicle list is introduced as an intermediary element between the user and the map display. The list presents vehicles in a selectable format, allowing users to easily identify and choose vehicles of interest. This intermediary layer simplifies the user's task of finding desired vehicles while the system handles the complex repositioning automatically.
2Quantity of substance
If multiple vehicles are displayed on the map image, then comprehensive vehicle information is provided, but it becomes difficult to focus on and manage information for specific vehicles
Solution Approach 1:
The display is segmented into two functional areas: a vehicle list showing multiple vehicles with their basic information, and a map image showing spatial positions. This segmentation allows users to browse multiple vehicles systematically in the list while the map provides spatial context. The user can focus on specific vehicles by selecting them from the list, which then becomes the center of attention on the map.
Solution Approach 2:
The map image dynamically adjusts its center position based on the selected vehicle. When a user selects a vehicle from the list, the map automatically repositions to center that vehicle, making it the focal point. This dynamic behavior allows comprehensive display of multiple vehicles while enabling easy focus on specific ones when needed.
3Ease of operation
If the map image center is fixed, then the map structure is simple and stable, but the user cannot easily view information on desired vehicles by positioning them at the center
Solution Approach 1:
The map image center position is made dynamic rather than fixed. The system automatically calculates and adjusts the center position based on the selected vehicle's location. This dynamic adjustment is achieved through programmatic control that determines the appropriate center position and updates the map display accordingly, resolving the contradiction between fixed simplicity and flexible usability.
4Ease of operation
If sequential button operation is required to display different vehicles, then the control mechanism is simple, but the user cannot directly select and focus on vehicles of interest
Solution Approach 1:
The system performs preliminary actions by preparing a sorted and organized vehicle list that presents all vehicles with their key information in an easily scannable format. Users can quickly identify vehicles of interest from this pre-organized list and select them directly, eliminating the need for sequential button operations. The system is ready to immediately reposition the map when a selection is made.
Solution Approach 2:
The vehicle list serves as an intermediary that provides direct access to all vehicles. Instead of requiring sequential navigation through buttons, the list presents vehicles in a structured format where users can visually scan and directly select the desired vehicle. This intermediary layer dramatically reduces the time to find and select vehicles of interest.

AI summary
A display control device including: an acquiring unit configured to acquire location information items representing locations of each of a plurality of vehicles and a plurality of status information items representing statuses of each of the plurality of vehicles, the plurality of vehicles being registered in advance in association with a user using a user terminal; a setting receiving unit configured to receive a display condition set by the user; and a display control unit configured to display a map image on the user terminal such that an icon image representing a vehicle whose status information item satisfies the display condition is positioned at the center of the map image and a position of the icon image of the vehicle in the map image corresponds to the location of the vehicle represented by the location information item.
