Embodiment 1

1 and 2 are block diagrams showing the configuration of the DSRC vehicle mounting apparatus according to the first embodiment of the present invention.

As shown in FIG. 1, the DSRC vehicle mounting apparatus according to Embodiment 1 of the present invention includes a vehicle mounting apparatus main body 10, an antenna portion 11, a push button switch 12, a display portion 13, and an audio. The generator 14 is provided.

The on-board main body 10 has a digital circuit 15 and a connection portion 16 built therein.

In addition, the connection part 16 is arrange | positioned so that it may be connected with the IC card 18 inserted from the IC card insertion opening 17 of the vehicle mounting body main body 10. As shown in FIG.

The IC card 18 stores vehicle information indicating a registration number of the vehicle and the like.

In addition, although the structure in which the antenna part 11 is provided in the exterior of the vehicle mounting body main body 10 is shown in FIG. 1, the antenna part 11 may be built in the vehicle mounting body main body 10. As shown in FIG.

As the display unit 13, a display device such as LCD or FL tube is used.

The push button switch 12, the display portion 13 and the sound generator 14 are connected to the digital circuit 15 via a cable.

The digital circuit 15 has a CPU (not shown).

The CPU modulates or demodulates the information communicated between the hearth (not shown) and the antenna unit 11, or calculates various kinds of information for recording on the IC card 18 inserted into the connection unit 16. Has the function

The information items stored in the IC card 18 inserted from the IC card insertion opening 17 or the information stored in the digital circuit 15 can be selected through the push button switch 12.

3 and 4 are conceptual diagrams for illustratively displaying a situation in which the DSRC vehicle mounting apparatus of the present invention is installed in a vehicle.

As described above, the DSRC vehicle mounting apparatus of the present invention has a push button switch 12 serving as an operation unit independent of the vehicle mounting body main body 10, and the display unit 13 and the sound generating device 14 are also mounted on the vehicle mounting body main body 10. Since it is independent from the vehicle, the vehicle mounting body main body 10 can be miniaturized.

3 and 4 also show a remote control receiver 21 to be described.

Therefore, as shown in FIG. 3 and FIG. 4, the DSRC vehicle mounting apparatus of the present invention can be efficiently installed using a large amount of space in the vehicle.

For example, the antenna unit 11 may be installed in a place having a good radio sensitivity such as above the dashboard.

The display unit 13 and the sound generating device 14 may be installed at a place where visibility is good and sound is good, such as a dashboard center.

In addition, the display part 13 shown in FIG. 3 is fitted in the dashboard, and the display part 13 shown in FIG. 4 is being fixed to the dashboard surface.

Since the push button switch 12 can be provided in the place which is easy to operate, respectively, it can provide the DSRC vehicle mounting apparatus which is easy to use.

In addition, the IC card insertion opening 17 may be provided in a place where the user can easily insert the IC card 18. Since the vehicle mounting body main body 10 is small, the IC card insertion opening 17 may be installed using a little space such as under the seat.

As described above, the DSRC vehicle mounting apparatus of the present invention separates the vehicle mounting body main body 10, the push button switch 12, and the like, so that the range that can be installed is widened, and the freedom in designing the vehicle can be realized. have.

In addition, although the antenna part 11 shows the DSRC vehicle mounting machine independent from the vehicle mounting body main body 10, the antenna part 11 does not necessarily need to be independent of the vehicle mounting body main body 10, It may be built in the main body 10.

Even when the DSRC vehicle is mounted in such a configuration, the push button switch 12 display portion 13 and the sound generating device 14 are independent of the vehicle body main body 10, and thus the same effects as described above can be obtained.

In addition, although the sound generating device 14 shows a DSRC vehicle mounting unit independent from the vehicle mounting body main body 10, since the audio generating device 14 has a relatively high degree of freedom in placement, the vehicle mounting body main body 10 It is not necessary to be independent from the), and may be incorporated in the vehicle body main body 10, as shown in FIG.

Even in the DSRC vehicle mounting apparatus having such a configuration, since the antenna unit 11, the push button switch 12, and the display unit 13 are independent of the vehicle mounting body main body 10, the same effects as those described above can be obtained.

In a vehicle equipped with a navigation system, the display unit 13 and the voice generator 14 may be used as a display unit or a voice generator of the navigation system. Cost reduction of utilization and DSRC vehicle mounting can be achieved.

In addition, the display unit 13 may be incorporated in a speed meter, and the audio generator 14 may use a car audio speaker.

In addition, if a connector is provided at one end or both ends of the cable connecting the digital circuit 15, the push button switch 12, the display portion 13, and the sound generating device 14, the installability of the DSRC vehicle mounter can be improved. have.

Embodiment 2

5 is a diagram conceptually showing a configuration of a DSRC vehicle mounting apparatus according to Embodiment 2 of the present invention.

As shown in FIG. 5, the DSRC vehicle mounting apparatus according to the second embodiment of the present invention replaces the push button switch 12 of the DSRC vehicle mounting apparatus according to the first embodiment with a remote control operation unit 20 and a reception unit 21. ).

Other configurations are the same as those shown in FIG.

The receiver 21 is provided outside the vehicle mounting apparatus 10 and is connected to the digital circuit 15 via a cable.

In the DSRC vehicle mounting apparatus having such a configuration, when the remote control operation unit 20 uses the remote control operation unit 20 to transmit a command to the reception unit 21, the driver can operate the DSRC vehicle mounting unit at any place.

Moreover, since the receiving part 21 is generally smaller than a push button switch, the freedom degree at the time of installation can be improved rather than the DSRC vehicle mounting apparatus which concerns on Embodiment 1 provided with a push button switch.

The remote control operation unit 20 may be incorporated into the remote control operation unit of the navigation system, or may be incorporated into the remote control operation unit of the car audio.

In addition, when the receiving unit 21 is provided near the display unit 13, the user can select various types of information through the limiter operating unit 20 while looking at the display unit 13, thereby achieving a representative improvement in operability.

Embodiment 3

6 is a diagram conceptually showing the configuration of the DSRC vehicle mounting apparatus according to the third embodiment of the present invention.

As shown in FIG. 6, the DSRC vehicle mounting apparatus according to the third embodiment of the present invention is separated from the vehicle mounting apparatus main body 10 by the IC card insertion opening 17.

All other configurations correspond to the configurations shown in FIG. 1.

In this way, if the IC card insertion opening 17 is independent from the vehicle mounting body 10, not only can the vehicle mounting body 10 be reduced in size, but also the freedom of installation place of the vehicle mounting body 10 is further increased. For example, the vehicle mounting body 10 may be installed in a trunk room of a vehicle.

Moreover, since the IC card insertion opening 17 itself is small, it can be arranged in a place where the user can easily insert the IC card 18, and the operability of the DSRC vehicle mounting device can be greatly improved.
