The electronic key stores a first threshold defining an extension of a first region in which an electric field intensity of a response request signal is strong and a second threshold for defining an extension of a second region in which an electric field intensity is weaker than the first region around the first region. The electronic key outputs, based on the electric field intensity of the response request signal and the first and second thresholds, a response signal including position information indicating whether the electronic key is in the first region, or is outside the first region but in the second region, or is outside the second region. Based on the received response signal, the in-vehicle device switches the door to an unlocked state or a locked state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Door locking device for vehicle","description":"This door locking device for a vehicle includes: an electronic key and an in-vehicle device.
