  By the way, in the apparatus described in the above-mentioned document, it is necessary to perform personal authentication, that is, to associate them while monitoring the positions of both the occupant and the mobile terminal in the vehicle. For this reason, an increase in calculation load is inevitable, for example, the processing logic accompanying the recognition of these positions becomes complicated.

  The target of association with the passenger in the vehicle is not limited to the above portable terminal, but may be any portable information medium that can specify personal information such as an IC (Integrated Circuit) card for personal possession.

  The present invention has been made in view of such a situation, and an object of the present invention is to provide a vehicular authentication apparatus capable of more easily performing personal authentication, that is, associating an occupant in a vehicle with a portable information medium. It is to provide.

Hereinafter, means for solving the above-described problems and the effects thereof will be described.
An authentication device for a vehicle that solves the above-described problem is provided at a specific position in a vehicle, and obtains personal information of an owner from a portable information medium through wireless communication, and around the communication unit at the specific position. An imaging unit that captures an image; an image processing unit that recognizes an operator of the portable information medium based on an image indicating an approaching operation of the portable information medium to the communication unit captured by the imaging unit; and the communication unit A personal authentication processing unit that personally authenticates the operator of the portable information medium by associating the acquired personal information with the information of the operator recognized by the image processing unit.

  According to the above configuration, the personal information of the owner acquired from the portable information medium by the communication unit when the operator brings the portable information medium closer to the communication unit corresponds to the operator information recognized by the image processing unit at that time. As a result, the operator of the portable information medium is personally authenticated. Therefore, personal authentication, that is, the association between the passenger in the vehicle and the portable information medium can be performed more easily.

The block diagram which shows schematic structure of one Embodiment of the authentication apparatus for vehicles. The perspective view which shows an example of the structure in the vehicle by which the authentication apparatus for vehicles of the embodiment was mounted.

Hereinafter, an embodiment of a vehicle authentication device will be described with reference to the drawings.
As shown in FIG. 1, the vehicular authentication apparatus of the present embodiment includes a communication unit 11 that performs short-range wireless communication with a mobile terminal T owned by a vehicle occupant. The communication unit 11 receives the owner's personal information (for example, “Mr. A's mobile terminal”) from the mobile terminal T, and outputs the received personal information to the personal authentication processing unit 12.

  In addition, the authentication device includes a distance image sensor 13 that detects an occupant of the vehicle by imaging an area including the periphery of the communication unit 11 in the vehicle. As a detection method of such a distance image sensor 13, for example, a TOF (Time Of Flight) method can be adopted. The distance image sensor 13 outputs image information of the vehicle occupant to the image processing unit 14.

  The image processing unit 14 performs image recognition processing on the occupant image information acquired from the distance image sensor 13. In this image recognition process, the image processing unit 14 determines whether or not the tip of the passenger's arm is within a predetermined distance from the communication unit 11. And when it determines with it being in the same range, it recognizes that the passenger | crew who is the object of the image recognition process is operating the portable terminal T close to the communication part 11. Then, the image processing unit 14 outputs the recognized operator information (for example, “the passenger in the driver's seat is operating the mobile terminal to approach”) to the personal authentication processing unit 12.

  The personal authentication processing unit 12 associates the occupant operator information acquired from the image processing unit 14 with the personal information acquired from the communication unit 11. Then, the personal authentication processing unit 12 personally authenticates the occupant who has operated the mobile terminal T close to the communication unit 11, and generates authentication information (for example, “A passenger in the driver's seat is Mr. A”).

Next, operation | movement of the authentication apparatus for vehicles of this Embodiment is demonstrated with reference to FIG.
In the example shown in FIG. 2, the communication unit 11 is provided at the center position in the vehicle body width direction of the dashboard 15 in the vehicle, and the distance image sensor 13 is provided at a location in front of the driver's seat on the dashboard 15.

  And in this example, since the passenger | crew P of a driver's seat is operating the portable terminal T approaching to the communication part 11, the communication part 11 receives the personal information of the owner of the portable terminal T from the portable terminal T. At the same time, the received personal information is output to the personal authentication processing unit 12 (FIG. 1).

  At this time, the distance image sensor 13 captures an image of the occupant P in the driver's seat performing the approaching operation, and outputs image information of the occupant P to the image processing unit 14 (FIG. 1). Then, the image processing unit 14 performs image recognition processing on the image information acquired from the distance image sensor 13, thereby recognizing that the subject of the approaching operation is the occupant P in the driver's seat. Then, the image processing unit 14 outputs the recognized operator information to the personal authentication processing unit 12.

  Thereafter, the personal authentication processing unit 12 associates the operator information indicating that the subject of the approaching operation is the driver's seat occupant P with the personal information of the owner of the mobile terminal T, thereby determining the driver's seat occupant P. Personal authentication. And the personal authentication process part 12 outputs the authentication information to various vehicle equipment. This authentication information is used as information that makes it possible to provide services suitable for the owner of the portable terminal T in the driver's seat, such as mirror position control and seat position control.

As described above, according to the above embodiment, the following effects can be obtained.
(1) When the vehicle occupant P brings the mobile terminal T close to the communication unit 11, the personal information of the owner acquired by the communication unit 11 from the mobile terminal T is stored in the mobile terminal T recognized by the image processing unit 14 at that time. By associating with the operator information, the operator who brings the mobile terminal T close to the communication unit 11 is personally authenticated. Therefore, personal authentication, that is, the association between the passenger P in the vehicle and the portable terminal T can be performed more easily.

In addition, the said embodiment can also be implemented with the following forms.
In the above embodiment, a pattern method, a stereo method, or the like may be adopted as the detection method of the distance image sensor 13.

  In the above embodiment, the distance image sensor 13 may be provided at a location in front of the passenger seat on the dashboard 15. The distance image sensor 13 may be provided in front of both the driver seat and the passenger seat on the dashboard 15. The distance image sensor 13 is not limited to the dashboard 15 and may be provided in a heater control panel, a meter panel, an overhead console, or the like.

  In the above-described embodiment, the configuration using the distance image sensor 13 that three-dimensionally captures the vehicle occupant and its operation has been described as an example. You may make it use the vehicle-mounted camera imaged dimensionally. When the angle of view of the in-vehicle camera is narrow, the vehicle occupant and its operation may be captured by complementing images captured by a plurality of in-vehicle cameras.

  In the above embodiment, instead of the portable terminal T, a portable information medium that can specify personal information, such as an IC card for personal use, may be the target of the association. In this case, the operator of the portable information medium is authenticated by the occupant operating the portable information medium close to the communication unit 11.
