The arithmetic processing portion performs zero point correction to set zero point for an output from a gyro sensor. The control portion switches the display style from the normal display style to a correction-oriented display style in which display information is limited in response to the startup of the vehicle navigation device, and maintains the correction-oriented display style during a zero point correction period that is elapsed from the startup of the vehicle navigation device to a completion of the zero point correction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vehicle navigation device","description":"A vehicle navigation device includes a detection portion detecting a position and a travel direction of a vehicle, an arithmetic processing portion specifying the position and the travel direction of ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9766770","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.
