It is provided that the slope of the voltage-lambda characteristic curve is determined for an output voltage of the two-point lambda sensor and is compared to the slope of a reference voltage-lambda characteristic curve at equal output voltage, and the voltage offset is determined from a deviation of the determined slope of the voltage-lambda characteristic curve from the slope of the reference voltage-lambda characteristic curve. Also described is a control unit for carrying out the method. The method and the control unit enable the determination of and compensation for a voltage offset of a two-point lambda sensor caused by aging or manufacturing tolerances."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and control unit for compensating for a voltage offset of a two-point lambda sensor","description":"A method is described for compensating for a voltage offset in a voltage-lambda characteristic curve of a two-point lambda sensor in relation to a reference voltage-lambda characteristic curve of the ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9696289","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.
