Document Type and Number:
WIPO Patent Application WO/2015/137185
Kind Code:
A1
Abstract:
An electronic key (10) executes keyless entry communication or RFID communication. A wireless control unit (32) is mounted on a vehicle and executes keyless entry communication within a range of a radius of several meters to several tens of meters. An RFID reader (34a-34c) is assigned to each door (DR1-DR3) and executes RFID communication within a range of a radius of approximately 1 meter. In regards to unlocking the door (DR1-DR3), the wireless control unit (32) issues a password by way of the keyless entry communication, and a wireless circuit (14) temporarily stores the issued password. The RFID reader (34a-34c) searches for the password stored in the electronic key (10) by way of the RFID communication, and the wireless control unit (32) unlocks a door corresponding to the RFID reader for which the password was detected.
