The vehicle-mounted device includes a plurality of antennas that is provided in different positions of a vehicle and is configured to transmit radio waves every predetermined time. A response signal based on the reception strength of the radio waves transmitted from the plurality of antennas is transmitted from the portable device to the vehicle-mounted device. The vehicle-mounted device determines that a moving direction of the portable device heads for any one of the antennas based on the response signal, and when it is determined that a distance between the vehicle and the portable device is equal to or less than a predetermined threshold, control is performed such that a door becomes unlocked."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electronic key device","description":"An electronic key device includes a portable device capable of being carried by a user, and a vehicle-mounted device configured to perform mutual communication with the portable device to perform pred","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9682684","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.
