In response to motor speed exceeding a threshold, the controller is configured to generate driver signals to operate the inverter switches to produce an active short circuit in the motor to prevent battery overcharging. A processor and electric circuit are each configured to independently generate an active short circuit control signal operative to effectuate generation of the driver signals, the active short circuit produced based on an active short circuit control signal from the electric circuit in an absence of an active short circuit control signal from the processor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for producing an active short circuit condition in an electric motor of a hybrid electric vehicle","description":"A system for producing an active short circuit in an electric motor of a hybrid electric vehicle having a traction battery includes an inverter to be provided in communication with the motor and batte","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11462920","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.
