Navigation System Sample Route Formation from Exploration Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation systems are ineffective in areas lacking or having unusable geodata, such as during adverse weather conditions, where they cannot provide reliable route guidance due to the absence of necessary spatial information.
Innovation Solution
A method to form a sample route by identifying and removing reversing sections from an exploratory route traveled, allowing the navigation system to create a usable route guidance even in areas with no or unusable geodata, by determining if a route section can be shortened and removing it from the exploratory route.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If navigation systems use traditional geodata-based route guidance, then route guidance is reliable in areas with complete geodata, but navigation systems become ineffective in areas lacking or having unusable geodata
Solution Approach 1:
The route is segmented into individual route sections that can be independently evaluated for reversals. By dividing the exploratory route into discrete segments, the system can identify and remove specific reversing sections while preserving the valid portions of the route, enabling navigation in areas without complete geodata.
Solution Approach 2:
The system performs preliminary analysis of the exploratory route to identify reversing sections before final route guidance is provided. By pre-processing the route data to detect and mark reversing sections, the system prepares a cleaned sample route that can be reliably used for navigation without requiring complete geodata for the entire area.
2Quantity of substance
If the exploratory route is used directly for navigation, then the route includes all traveled paths, but incorrect paths such as dead ends are included in the navigation route
Solution Approach 1:
The system extracts and removes reversing sections from the exploratory route to create a cleaned sample route. By identifying route sections where the vehicle reversed direction and removing these problematic segments, the system preserves the complete valid portions of the route while eliminating incorrect paths like dead ends, thus maintaining route completeness while improving correctness.
3Reliability
If reversing sections are removed from the exploratory route, then the sample route avoids dead ends and incorrect paths, but the route processing complexity increases
Solution Approach 1:
The system uses dynamic evaluation of route sections based on directional changes and spatial relationships. By continuously assessing whether consecutive route sections represent reversals (using tolerance distances and direction analysis), the system adaptively identifies and removes only the necessary problematic segments without requiring complex manual processing of the entire route.

AI summary
The invention relates to a navigation system (100) and a method for operating a navigation system (100). In this process, a reconnaissance route (300, 400, 500) is determined using the navigation system (100), it is checked whether the reconnaissance route (300, 400, 500) has a turning section (320, 420), and, if the reconnaissance route (300, 400, 500) has a turning section (320, 420), a model route that does not have the turning section (320, 420) is generated from the reconnaissance route (300, 400, 500).
