Also, the vehicle-mounted emergency report device has a first determination unit determining whether the voltage detected is lower than a battery exhaustion warning threshold, a second determination unit determining whether a second order differential coefficient calculated by differentiating a battery voltage function twice by time is negative, and a warning unit refraining from warning when the voltage detected is lower than the threshold and the coefficient is not negative, and warning when the coefficient is negative. Thus, decrease of a discharge performance of the backup battery can be detected accurately."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vehicle-mounted emergency report device","description":"A vehicle-mounted emergency report device having a function of transmitting an emergency report signal to a center device via a communication network when a vehicle has been determined to collide, inc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9616835","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.
