The portable machine includes an LF receiver receiving the response request signal and a UHF transmitter transmitting a response signal. The LF receiver in the portable machine has a reception region in which the response request signals transmitted from at least two of the LF transmitters are receivable when the portable machine approaches the vehicle. Door locking/unlocking is permitted if the LF receiver in the portable machine receives the response request signals transmitted from at least two of the LF transmitters within a predetermined time period. In contrast, door locking/unlocking is inhibited if the LF receiver receives the response request signal transmitted from one of the LF transmitters."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vehicle wireless communication system, vehicle control device, and portable machine","description":"A vehicle control device includes a plurality of LF transmitters transmitting response request signals that reach an area around a vehicle and an interior of a vehicle chamber, and a UHF receiver rece","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9805532","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.
