The in-vehicle system operates in an alert mode when a vehicle is parked, and transmits an authentication signal including a strength change signal. When the in-vehicle system operates in an alert cancellation mode, the mobile device returns a response signal only when there is a change in the strength of the received authentication signal. When the in-vehicle system succeeds in authentication of the mobile device in an authentication process in the alert mode, the in-vehicle system shifts to the alert cancellation mode. When the in-vehicle system operates in the alert cancellation mode, the mobile device returns the response signal irrespective of whether there is the change in the strength of the received authentication signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vehicular electronic key system with determination of transmission strength adjustment","description":"An in-vehicle system executes authentication of a mobile device multiple times from a parking state until an engine is started.
