  • Publication number: 20240257590
    Abstract: A smart key and a mobile terminal store therein key information to be used for authentication with a vehicle to function as a key (key device) of a vehicle. Each of the smart key and the mobile terminal performs communication for authentication with an in-vehicle system or the like by BLE communication. For power saving, the smart key basically operates in a sleep mode in which the BLE communication is not possible. On receiving a wake signal periodically transmitted from the vehicle, the smart key transitions to a state where the BLE communication is possible. When sensing the presence of the mobile terminal within a predetermined distance from the vehicle, the in-vehicle system stops the periodic transmission of the wake signal.
