The driving assistance device further includes a position estimation unit that estimates a vehicle position with respect to the past traveling positions and adds a history of the estimated position to the past traveling position, in addition to a deviation determination unit that determines deviation from the past traveling positions using a distribution of the past traveling positions, the vehicle position relative to the past traveling positions, and a reference value. The driving assistance device includes a control unit that controls the vehicle to cancel a warning or deviation when the deviation is determined."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Driving assistance device and driving assistance system","description":"A driving assistance device includes a recording unit that records vehicle past traveling positions and related position estimation information, and a relative position estimation unit that estimates ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11941983","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.
