The method also includes forming a polygon or a closed curve from the mathematical hull of all points in the maximum theoretical range having a value function solution less than corresponding limit, and displaying a perimeter of the closed curve via the display screen to indicate the effective range of the vehicle for the criterion. A vehicle includes an energy storage system, a motor/generator unit for propelling the vehicle in an electric-only (EV) mode, the display screen, and host machine, wherein the criterion is the EV mode. A method of operating the display system is also disclosed herein."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for calculating and displaying travel range information","description":"A display system for a vehicle includes a display screen and host machine operable for calculating a maximum theoretical range for a predetermined criterion, formulating a value function for each poin","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8527121","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.
