Digital Map Release Using Infrastructure Suitability Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital maps used for infrastructure-based, at least partly automated guidance of motor vehicles within infrastructure are often outdated, leading to potential safety and security issues due to inaccuracies in object locations and properties, necessitating a method to ensure the map's suitability before use.
Innovation Solution
A method that involves receiving area signals from infrastructure, testing the digital map for suitability by comparing it with actual infrastructure conditions, and releasing the map only if it is found suitable, with updates made if discrepancies are detected, ensuring the map is up-to-date and accurate for safe and secure automated vehicle guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital maps are used for infrastructure-based automated guidance without prior suitability testing, then the system operates with higher speed and productivity, but the reliability and safety deteriorate due to outdated map data
Solution Approach 1:
The patent applies preliminary action by performing suitability testing of digital maps before they are released for use in automated guidance systems. The testing process compares digital map data with actual infrastructure conditions (using area signals from sensors) in advance, ensuring map accuracy is verified prior to deployment. This prevents outdated maps from being used while maintaining efficient operations.
2Reliability
If digital maps are frequently updated to maintain accuracy, then the reliability improves, but the device complexity and processing requirements increase
Solution Approach 1:
The system applies self-service by enabling automated suitability testing where the digital map is automatically compared against actual infrastructure conditions using area signals from environmental sensors. The process autonomously determines whether the map remains suitable for use without requiring manual intervention, reducing operational complexity while maintaining high reliability through continuous validation.
