  • Patent number: 10373043
    Abstract: A radio IC device includes an electromagnetic coupling module includes a radio IC chip arranged to process transmitted and received signals and a feed circuit board including an inductance element. The feed circuit board includes an external electrode electromagnetically coupled to the feed circuit, and the external electrode is electrically connected to a shielding case or a wiring cable. The shielding case or the wiring cable functions as a radiation plate. The radio IC chip is operated by a signal received by the shielding case or the wiring, and the answer signal from the radio IC chip is radiated from the shielding case or the wiring cable to the outside. A metal component functions as the radiation plate, and the metal component may be a ground electrode disposed on the printed wiring board.

  • Patent number: 10147250
    Abstract: An electronic key executes keyless entry communication or RFID communication. A wireless controller mounted on a vehicle executes keyless entry communication within a range of a radius of several meters to several tens of meters. An RFID reader is assigned to each door and executes RFID communication within a range of a radius of approximately 1 meter. In regards to unlocking the door, the wireless controller issues a password by the keyless entry communication, and a wireless circuit temporarily stores the issued password. The RFID readers search for the password stored in the electronic key by the RFID communication, and the wireless controller unlocks a door corresponding to the RFID reader for which the password was detected.

  • Patent number: 9997000
    Abstract: An electronic key actively executes wireless communication following a keyless entry communication and passively executes wireless communication following a RFID communication. A vehicle control device is mounted on a vehicle and actively executes wireless communication following each of the keyless entry communication and RFID communication. An ECU/BCM unlocks a door by communicating with the electronic key using the keyless entry communication and issues a password to the electronic key in relation to this action. When a door knob or handle is pulled, an RFID-IC acquires the password issued by the ECU/BCM from the electronic key using the RFID communication and unlocks the door by authenticating the acquired password.
