Travel Control Map Route Association Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing travel control systems face difficulties in associating route information from navigation maps with travel control maps, leading to unclear sections where automatic driving is challenging, and it is hard to predefine travel control impossible roads.
Innovation Solution
A travel control system that includes a route search map unit and a travel control map unit, which collate and associate route information using coordinate and attribute data, and adjust search routes to avoid unclear sections by re-routing around correspondence-unclear areas, ensuring accurate mapping and continuous travel control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If route search is performed using navigation map information, then route guidance can be provided to occupants, but the route information cannot be directly associated with travel control map information due to different expression formats
Solution Approach 1:
The patent introduces an intermediary process that converts navigation map route information into travel control map compatible format. The route search unit obtains routes from navigation maps, then the system performs format conversion and association processing to bridge the two different map expression formats, enabling both route guidance and accurate travel control execution
Solution Approach 2:
The patent segments the route information processing into distinct components: route search based on navigation maps, format conversion processing, and travel control execution based on converted maps. This segmentation allows each component to handle its specific function while maintaining overall system reliability
2Adaptability or versatility
If travel control is performed using separate map information management, then navigation and travel control can operate independently, but it becomes indispensable to manually associate route information with travel control map information
Solution Approach 1:
The patent merges the route search function and travel control function into a unified system architecture. The route search unit and travel control map unit operate independently for their respective functions, but the system automatically combines them through format conversion and association processing, eliminating manual association requirements while maintaining independent operation capabilities
3Adaptability or versatility
If abstraction conversion to industry standard format is performed, then map association becomes possible, but correspondence-unclear sections remain where travel control cannot be substantially performed
Solution Approach 1:
The patent performs preliminary format conversion and association processing before travel control execution. By pre-converting navigation map route information into travel control map format and identifying correspondence-unclear sections in advance, the system can plan alternative routes or provide advance notices to occupants, ensuring travel control continuity

AI summary
The present invention provides an information processing apparatus and a travel control system capable of reducing a correspondence-unclear section, generated when associating route information to a destination on a travel control map, as small as possible in a driving support function of supporting driving by automating some or all of driving operations of an occupant so as to continue travel control along an appropriate route in as long a section as possible. In the present invention, a search route searched based on a route search map different from a travel control map is collated with the travel control map, and correspondence unclearness information is output when a part or a whole of the search route has unclear correspondence with the travel control map. In addition, a search for a search route different from the initial search route is performed based on the output correspondence unclearness information.
