Dual antenna initiator coils are mounted to a vehicle such that each wheel end has one directional antenna directed toward it. Each initiator coil is programmed to modulate its transmission frequency by a predetermined modulation frequency such that each antenna transmits using a different modulation frequency. Each sensor receives a modulated signal, identifies the modulation frequency, and performs a table lookup to determine its axle and wheel end location. The sensor transmits its identified wheel end and axle location to a controller unit along with tire pressure status information for its wheel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"TPMS sensor autolocation through low frequency programming","description":"In order to mitigate a need for reprogramming tire pressure sensors after tire rotation, tire change, etc., all sensors on a vehicle are preprogrammed with a lookup table that correlates modulation fr","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9851227","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.
