Dynamic Map Scale Adjustment for Destination Approach
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems fail to provide drivers with sufficient dynamic map scaling and relevant environmental information when approaching a destination, leading to potential missed arrivals, especially in unfamiliar areas.
Innovation Solution
A navigation system with a dynamic map display apparatus that automatically changes map scale and prioritizes map attributes based on a predefined list, searching for and displaying relevant features like major streets, POIs, or landmarks within a predetermined distance of the destination to enhance driver awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the map scale is changed dynamically to display more environmental information near the destination, then the driver's ability to visualize the destination environment is improved, but the system complexity increases
Solution Approach 1:
The map scale is changed dynamically based on the vehicle's distance to the destination. When the vehicle approaches within a predetermined distance of the destination, the system automatically switches to a larger map scale to display more detailed environmental information such as major streets, landmarks, and points of interest near the destination, rather than using a fixed map scale throughout the journey.
Solution Approach 2:
The system applies different map scales to different spatial regions: a smaller scale is used for the overall route display when the vehicle is far from the destination, while a larger scale is applied locally when the vehicle approaches the destination to show detailed environmental information. This localized adjustment provides relevant information without overwhelming the driver with unnecessary detail throughout the entire journey.
2Loss of information
If the map displays detailed environmental information near the destination, then the driver can better visualize the destination environment, but the driver may become distracted from safe driving
Solution Approach 1:
The system dynamically adjusts the map scale based on the vehicle's proximity to the destination, automatically switching to a detailed view only when the vehicle is within a predetermined distance. This eliminates the need for manual driver intervention to change map scales, reducing distraction while ensuring detailed information is available when most needed for destination identification.
Solution Approach 2:
The navigation system automatically determines when to switch map scales based on GPS position data and predetermined distance thresholds, without requiring driver input. The system self-adjusts the display to provide detailed environmental information at the appropriate moment, reducing cognitive load on the driver compared to manual operation.
3Ease of operation
If the map scale is changed manually by the driver, then the driver can control the information displayed, but the driver is distracted from safe driving
Solution Approach 1:
The system performs the map scale adjustment function automatically based on the vehicle's position relative to the destination, eliminating the need for manual driver operation. The navigation system monitors GPS data and autonomously switches between map scales, providing the benefits of manual control without the distraction of manual intervention.
Solution Approach 2:
The system continuously monitors the vehicle's position through GPS and uses this feedback to automatically adjust the map scale. When the vehicle approaches within a predetermined distance of the destination, the system detects this condition and automatically switches to a larger map scale to display detailed environmental information, creating a closed-loop control system that responds to real-time conditions.
4Measurement precision
If the map displays the highest possible scale at specific points, then the driver can visualize those specific points, but the destination may still be difficult to visualize if the search ending point is far from the destination
Solution Approach 1:
The system replaces the conventional approach of displaying fixed predetermined points (starting point, search beginning point, search ending point) with a dynamic destination-centered display. When the vehicle approaches within a predetermined distance of the destination, the system automatically switches to a larger map scale centered on the destination, ensuring that detailed environmental information is always displayed relative to the actual destination rather than arbitrary predetermined points.
Solution Approach 2:
The system applies detailed map display quality specifically in the destination area when the vehicle is within a predetermined distance, rather than uniformly applying high detail throughout the entire route. This localized high-detail display ensures that the destination environment is clearly visualized when the driver needs it most, while maintaining efficient overall route overview during the journey.

AI summary
A map display apparatus and method for a navigation changes a map scale dynamically to help the driver visualize the environment of the destination when the vehicle is approaching the destination. The map scale is changed dynamically to display the destination along with at least one map attribute near the destination to provide more information to the driver. The navigation system includes, among others, a searching unit and a scale changing unit to change the map scale to display the destination along with at least one map attribute when the vehicle is approaching the destination. The navigation system also includes a priority table to prioritize the map attributes and the searching unit searches the map attributes near the destination according to order in the priority table.
