The in-vehicle communication device may include: a first determination unit that determines whether messages received by the reception unit are periodic or non-periodic messages; and a second determination unit that, for a message determined as being periodic by the first determination unit, determines whether or not the periodic message has been transmitted at a predetermined cycle, and the abnormality detection unit may detect abnormalities in information included in periodic messages determined as having been transmitted at predetermined cycles by the second determination unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"In-vehicle communication device and information replacement method","description":"An in-vehicle communication device includes: an abnormality detection unit detecting abnormalities in in messages received by a reception unit receiving messages from one or more other devices; an est","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11936494","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.
