The vehicle-mounted device includes a vehicle-mounted transmission unit which simultaneously transmits radio waves having a predetermined phase difference using at least two transmission antennas disposed orthogonal to each other. The portable device includes a triaxial reception antenna receiving the at least two radio waves, and a magnetic field strength detection unit detecting a magnetic field strength on each of three axes of the triaxial reception antenna. One of the vehicle-mounted device or the portable device includes an illicitness determination unit determining, based on the detected magnetic field strength, whether the wireless communication is established through an illicit repeater."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vehicle system, portable device, and vehicle-mounted device","description":"A vehicle system includes a vehicle-mounted device mounted to a vehicle and a portable device portable by a user, and performs a control to the vehicle corresponding to a collation result performed ba","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9599984","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.
