  • Publication number: 20250042362
    Abstract: A master communication device causes a slave communication device connected to the master communication device to perform a distance measurement communication for measuring a distance between a terminal and a vehicle that wirelessly communicates with the terminal. The master communication device notifies a controller connected to the master communication device of a first result of the distance measurement communication performed by the slave communication device. The master communication device further notifies the controller of a second result of the distance measurement communication performed by the master communication device. The vehicle is permitted to be actuated in response to any one of the first result or the second result indicating that the distance is valid.
