In-Vehicle Lane Display Layout for Recommended Lane Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation devices struggle to display all travel lanes in the same direction as a recommended lane, making it difficult for drivers to determine optimal lane changes, especially in complex environments.
Innovation Solution
A display system that identifies and displays a recommended lane and the maximum number of travel lanes in the same direction within a predetermined number of display boxes, allowing drivers to easily assess lane changes and reduce unnecessary movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the navigation device displays only a limited number of lanes (including travel lane and recommended lane), then the display complexity is reduced, but the driver cannot see all lanes in the same direction as the recommended lane, making it difficult to determine optimal lane changes
Solution Approach 1:
The display is divided into multiple display boxes, each showing a specific lane. This segmentation allows the system to present multiple lanes (including all lanes in the same direction as the recommended lane) in an organized, non-overlapping manner, enabling drivers to see more lanes without creating display chaos
Solution Approach 2:
The system transitions from displaying lanes in a single linear sequence to a two-dimensional grid arrangement with multiple display boxes. This dimensional change allows simultaneous presentation of multiple lanes (travel lane, recommended lane, and other lanes in the same direction) without increasing horizontal scroll complexity
2Loss of information
If the navigation device displays all available lanes, then the driver has complete information about all lanes, but the display becomes complex and difficult to read when the number of lanes exceeds the display capacity
Solution Approach 1:
The display area is segmented into multiple fixed display boxes arranged in a grid. Each box independently displays one lane, creating a structured layout that prevents display chaos even when showing multiple lanes simultaneously
Solution Approach 2:
Different display boxes are assigned specific functions: some display the travel lane, others display the recommended lane, and others display additional lanes in the same direction. This local differentiation allows each box to serve its specific purpose while contributing to the overall comprehensive display
3Ease of operation
If the navigation device prioritizes displaying the recommended lane, then the recommended lane is always visible, but other lanes in the same direction may be omitted, reducing the driver's ability to assess alternative options
Solution Approach 1:
The display is segmented into multiple boxes where the recommended lane occupies one box and other lanes in the same direction occupy additional boxes. This segmentation ensures the recommended lane remains prominently visible while simultaneously displaying alternative lanes for comparison
Solution Approach 2:
The multiple display boxes serve universal functionality by all displaying travelable lanes in the same direction as the recommended lane. Each box can independently show a different lane, making the display system versatile in presenting various lane options while maintaining focus on the recommended lane

AI summary
An in-vehicle device displaying travel lanes of a vehicle in a predetermined number of display boxes includes an identifying part that identifies travel lanes to be displayed in the display boxes, and identifies travel lanes so a recommended lane which is a travel lane recommended for the vehicle to travel is displayed in one of the display boxes and a maximum number of recommended travel lanes which are travel lanes coinciding with a traveling direction of the recommended lane each are displayed in one of the display boxes; and a display part that displays the identified travel lanes in the display boxes. The identifying part identifies travel lanes while relatively shifting in turn a plurality of travel lanes and the display boxes from a travel lane at one end of the plurality of travel lanes that are on a traveling direction side of the vehicle and being adjacent to each other.
