Navigation System Detects Route Segments for Map Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users driving frequently traveled routes without active route guidance are not informed of changes in the road network, such as speed limits, traffic conditions, or roadworks, which can lead to dangerous situations due to unexpected changes.
Innovation Solution
A computer-implemented method that determines if a vehicle is likely to travel along frequently covered route segments, selects associated map data changes, and generates travel information based on these changes, providing early warnings or instructions to the driver, even when route guidance is inactive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the user travels along frequently covered routes without active route guidance, then the user can drive more efficiently and quickly, but the user will not be informed of map data changes or road network modifications which may lead to dangerous situations
Solution Approach 1:
The system continuously monitors the vehicle's position and compares it with stored frequently covered routes, then provides feedback information about map data changes along those routes. This feedback mechanism ensures drivers are informed of road network modifications without requiring active route guidance, thus maintaining driving efficiency while preventing information loss.
Solution Approach 2:
The navigation device automatically detects when the vehicle is traveling along a frequently covered route and autonomously provides information about map data changes without requiring user input or activation of route guidance. The system serves itself by utilizing its own stored route data and map data to generate relevant notifications.
2Ease of operation
If the user does not enter destination information for frequently visited locations, then the user can avoid unnecessary route guidance interruptions, but the navigation device cannot provide updated information on road network changes
Solution Approach 1:
The system pre-stores frequently covered routes and their associated map data changes in the navigation device. Before the user even enters destination information, the system has already prepared the route data and can immediately provide information about road network changes when the vehicle is detected to be traveling along these pre-stored routes.
Solution Approach 2:
The system uses the vehicle's position data and stored route information as an intermediary to bridge the gap between the user's frequent travel patterns and the need for updated road information. Instead of requiring direct user input, the system mediates by automatically matching current position with stored routes and providing relevant map data change information.
3Reliability
If the map data database is frequently updated to reflect road network changes, then the information on route segments is kept current, but the user traveling without active route guidance remains unaware of these changes
Solution Approach 1:
The system segments the map data updates by identifying specific route segments that have changed and only providing information about changes along the user's current frequently covered route. Instead of notifying the user of all database updates, the system divides and delivers only the relevant segment-specific information, making the user aware of changes without overwhelming them.
Solution Approach 2:
The system applies local quality by providing customized information about map data changes specific to the user's current location and route. The information delivery is tailored to the local context of the user's travel, providing details about road network changes only in the relevant geographic area where the user is currently driving.

AI summary
A technique is described for providing travel information for route segments repeatedly covered by a vehicle, wherein the travel information is indicative of map data changes extractable from map data update information. A method aspect comprises the steps of determining whether the vehicle is likely to travel along repeatedly covered route segments; selecting map data changes that are associated with the repeatedly covered route segments the vehicle is likely to travel; and generating travel information on basis of the selected map data changes and providing the travel information to a driver. Provided are also a computer program product and a device implementing the described method.
