Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicles lack the capability to autonomously navigate and park in spaces without pre-existing digital map data, especially in complex environments like parking garages.
Innovation Solution
A procedure that utilizes cameras to record and process image data from the vehicle environment, transforming recognized overview maps into navigable digital cards, which guide the vehicle through the spatial area without relying on digital communication interfaces or pre-loaded map data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If digital map data of parking garages is provided via download through IT interfaces, then navigation capability is improved, but device complexity and data management requirements increase
Solution Approach 1:
The system enables the vehicle to autonomously capture, process, and generate its own digital map data from visual representations in the parking garage environment, eliminating the need for external data management infrastructure and pre-loaded maps
Solution Approach 2:
The patent replaces the mechanical/data-intensive system of pre-loaded digital maps and IT interfaces with an optical system that captures visual representations using cameras and processes them into navigable data structures in real-time
2Adaptability or versatility
If visual representations are captured and processed in real-time, then adaptability to environments without pre-existing data is improved, but use of energy and computational load increase
Solution Approach 1:
The system extracts only the essential navigational features from visual representations, converting them into simplified data structures that contain only the necessary information for path planning and obstacle avoidance, reducing computational requirements
Solution Approach 2:
The system performs preliminary processing of visual data by capturing images, identifying spatial features, and generating navigable representations in advance of actual navigation needs, allowing for more efficient real-time decision-making

AI summary
In the method according to the invention for using a digital map in a vehicle, image data from the vehicle surroundings are captured (1) using one or more cameras (7) of the vehicle (5). The captured image data are processed (2) so as to identify a visually displayed overview map (9) that contains an abstract representation of spatial circumstances in the vicinity of the overview map. The image data of an identified overview map (9) are transformed (3) into a navigable digital map. The digital map is used to generate (4) guidance information for a travel route in the spatial region displayed in the overview map.
