In digital wireless communication performed between a vehicle and an electronic key terminal, the electronic key terminal and the vehicle periodically perform advertising transmission at a first time interval, periodically perform, at a second time interval, verification communication of confirming whether authentication of the electronic key terminal is established after the advertising transmission, periodically perform, at a third time interval, periodic communication performed after the authentication is established in the verification communication, and set the third time interval of the periodic communication to be longer than the second time interval of the verification communication. Accordingly, the responsiveness of the communication between the electronic key terminal and the vehicle can be improved. In addition, the first time interval of the advertising transmission is set to be longer than the second time interval of the verification communication. Accordingly, a reduction in power consumption of the vehicle 1 can be achieved.
