The systems, methods, and programs generate course guidance information based on the determined estimated connection angle when the vehicle is determined to be exiting. Based on the vehicle location information and the road information, the systems, methods, and programs detect whether an actual traveling road and the guidance road differ. Based on the vehicle location information and the road information, the systems, methods, and programs correct the estimated connection angle at the exit/entrance node based on a relative angle between the actual traveling road and the guidance road, and record the corrected estimated connection angle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Course guidance system, course guidance method, and course guidance program","description":"Course guidance systems, methods, and programs determine that a vehicle is exiting from a facility to an out-of-facility road via an exit lane, and determine an estimated connection angle of the exit ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8489322","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
