Abstract

A communication apparatus for communicating with both of a vehicle control device, which performs vehicle control preliminary set in a vehicle when authentication with an authentication device carried by a user is successful, and a portable device, which functions as the authentication device, the communication apparatus also functioning as the authentication device, the communication apparatus includes: a to-portable-device communicator that performs wireless communication with the portable device when performing authentication with the vehicle control device; and an authenticator that performs authentication with the vehicle control device when wireless communication with the portable device is established.

First claim

What is claimed is:

1. A communication apparatus for communicating with both of a vehicle control device, which performs vehicle control preliminary set in a vehicle when authentication with an authentication device carried by a user is successful, and a portable device, which functions as the authentication device, the communication apparatus also functioning as the authentication device, the communication apparatus comprising:
a to-portable-device communicator that performs wireless communication with the portable device when performing authentication with the vehicle control device;
an authenticator that performs authentication with the vehicle control device when wireless communication with the portable device is established; and
a communication distance setting device that communicates with another communication apparatus in a facility, and sets a communicable distance according to the facility.

2. The communication apparatus according to claim 1 , wherein:
the to-portable-device communicator performs wireless communication with the portable device to acquire authentication information required for authentication with the vehicle control device from the portable device; and
the authenticator performs authentication with the vehicle control device using the authentication information acquired from the portable device.

3. The communication apparatus according to claim 1 , further comprising:
a communication information exchanger that exchanges communication information for performing communication with the portable device using a first communication method that enables communication by bringing the portable device closer to the communication apparatus.

4. The communication apparatus according to claim 1 , further comprising:
a start signal acquirer that acquires a start signal indicating start of authentication with the vehicle control device using a second communication method, wherein:
the to-portable-device communicator performs wireless communication with the portable device using a third communication method different from the second communication method when receiving the start signal.

5. The communication apparatus according to claim 4 , wherein:
the to-portable-device communicator transmits the start signal to the portable device.

6. The communication apparatus according to claim 4 , wherein:
the communication apparatus uses low frequency communication as the second communication method, and uses radio frequency communication as the third communication method.

7. A vehicle control device that performs vehicle control preliminary set in a vehicle when authentication with an authentication device carried by a user is successful, and communicates with a communication apparatus as the authentication device, the vehicle control device comprising:
a communication monitor that monitors a communication state with the communication apparatus; and
a control inhibitor that inhibits continuation of the vehicle control when communication with the communication apparatus is interrupted, wherein:
the communication apparatus communicates with both of the vehicle control device, which performs the vehicle control preliminary set in the vehicle when the authentication with the authentication device carried by the user is successful, and a portable device, which functions as the authentication device;
the communication apparatus also functions as the authentication device;
the communication apparatus includes:
a to-portable-device communicator that performs wireless communication with the portable device when performing authentication with the vehicle control device; and
an authenticator that performs authentication with the vehicle control device when wireless communication with the portable device is established.

8. A vehicle control system comprising:
a vehicle control device that performs vehicle control preliminary set in a vehicle when authentication with an authentication device carried by a user is successful;
a portable device that functions as the authentication device; and
a communication apparatus that communicates with both the vehicle control device and the portable device, wherein:
the communication apparatus communicates with both of the vehicle control device, which performs vehicle control preliminary set in the vehicle when the authentication with the authentication device carried by the user is successful, and the portable device, which functions as the authentication device;
the communication apparatus also functions as the authentication device;
the communication apparatus includes:
a to-portable-device communicator that performs wireless communication with the portable device when performing the authentication with the vehicle control device;
an authenticator that performs authentication with the vehicle control device when wireless communication with the portable device is established; and
a communication distance setting device that communicates with another communication apparatus in a facility, and sets a communicable distance according to the facility;

the vehicle control device performs the vehicle control preliminary set in the vehicle when the authentication with the authentication device carried by the user is successful, and communicates with the communication apparatus as the authentication device; and
the vehicle control device includes:
a communication monitor that monitors a communication state with the communication apparatus; and
a control inhibitor that inhibits continuation of the vehicle control when communication with the communication apparatus is interrupted.

9. The communication apparatus of claim 1 , wherein
the communication distance setting device sets the communicable distance according to whether a notification has been received from the other communication apparatus located in the facility.

10. The vehicle control device of claim 7 , wherein
the vehicle control device further comprises a communication distance setting device that communicates with another communication apparatus in a facility, and sets a communicable distance according to the facility.
