Navigation Schematic Lane View Segmentation for Driver Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems struggle to maintain user orientation during multiple lane-changing maneuvers, as static schematic lane views can overwhelm drivers with irrelevant information, leading to disorientation.
Innovation Solution
The method involves continuously updating the schematic lane view based on the vehicle's current position, displaying only relevant lane-changing maneuvers within a predefined distance, and using a three-dimensional perspective representation to prioritize the next maneuver, ensuring a smooth and intuitive display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the maneuvering scheme view is displayed continuously showing all upcoming maneuvers, then the user has complete information about the route, but the user loses orientation due to the large number of maneuvers displayed simultaneously
Solution Approach 1:
The maneuvering scheme view is segmented into multiple individual images, each showing only the next maneuver to be performed. As the user progresses through the route, the display transitions from one maneuver image to the next, presenting information in manageable segments rather than overwhelming the user with all maneuvers at once. This segmentation maintains information completeness while improving orientability.
Solution Approach 2:
The maneuvering scheme view transitions from a static display showing all maneuvers to a dynamic sequence of individual maneuver images. The display updates automatically as the user progresses along the route, showing only the relevant next maneuver at each stage. This dynamic adaptation keeps the displayed information both complete and oriented to the user's current position.
2Loss of information
If the schematic lane view shows all lane-changing maneuvers in sequence, then the user has full route guidance, but the driver becomes disoriented due to the large number of maneuvers
Solution Approach 1:
The schematic lane view is divided into a sequence of individual lane diagrams, with each diagram showing only the next lane-changing maneuver. The system transitions through these diagrams sequentially as the driver progresses, presenting complete route guidance in segmented, manageable portions that prevent driver disorientation.
Solution Approach 2:
The schematic lane view transitions from a static comprehensive display to a dynamic sequential presentation. The system automatically advances through individual lane diagrams based on the vehicle's progress along the route, maintaining complete route guidance while adapting the display to show only relevant upcoming maneuvers, thereby preserving driver orientation.
3Loss of information
If multiple maneuvers are displayed in the schematic lane view, then the user has comprehensive navigation information, but the display becomes cluttered and hard to interpret
Solution Approach 1:
The navigation display segments the comprehensive maneuver information into individual maneuver images or lane diagrams. Each segment presents a single maneuver clearly and simply, while the sequence of segments collectively provides complete navigation information. This segmentation reduces display complexity while maintaining information completeness.
Solution Approach 2:
The display system dynamically transitions between segmented maneuver presentations rather than displaying all maneuvers simultaneously. This dynamic sequencing maintains navigation information completeness while keeping each individual display state simple and easy to interpret, avoiding clutter and reducing perceived device complexity.

AI summary
The method involves calculating a route from a starting point to a destination point, and obtaining the route from a sequence of route segments (02a to 02d) and nodes (03a,03b). The route is selected with a route calculation process from a database, in which a geographical area is described by route segments and nodes. The current position of the vehicle is detected during the display of a lane pattern plan. The lane pattern plan is displayed on a display unit.
