DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication system, an in-vehicle apparatus, and a recording medium capable of so-called road-to-vehicle communication, for example, between an automobile and various stores.

[0002]

2. Description of the Related Art In recent years, for example, ET on highways
Road-to-vehicle communication for communication between a vehicle and a road side has been studied as C (automatic charging system). This road-to-vehicle communication is, for example, a DSRC (Dedicated Short-Range Community).
ication) It is performed by narrow-area wireless communication called wireless.

In addition to the above-mentioned ETC, as an application for road-to-vehicle communication, for example, it is conceivable to perform communication between a vehicle and various roadside facilities (for example, stores) to receive various services.

[0004]

In such road-to-vehicle communication, it is necessary to consider various problems that occur when personal information (private information) is transmitted from a vehicle to a store or the like. For example, if personal information is freely transmitted from a vehicle in response to a request from a store, its safety becomes a problem.

[0005] On the other hand, there is also a problem that necessary services cannot be received unless personal information is transmitted to the store side. Further, although the road-vehicle communication is performed by the above-described narrow-area wireless communication, even in a narrow communication area, the communicable area may reach a public road.

[0006] In this case, even if there is no intention to receive the service, the personal information is freely communicated, and the system is switched to the system installed in the adjacent store one after another, and the screen is switched in units of several seconds, so that the practical use is not possible. Not a target. The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a communication system, a vehicle-mounted device, and a recording medium which are excellent in practicality by transmitting necessary information at a required timing. It is in.

D) Next, a description will be given of a process (setup process) for incorporating the application into the on-vehicle device in order to execute the application described above. First, an overview of road-vehicle communication for setup will be described with reference to the timing chart of FIG.

Here, an example is shown in which the setup at the hangar shop is performed by road-to-vehicle communication. That is, as shown in FIG. 4, first, road-to-vehicle communication is performed between the roadside device and the on-vehicle device using a frame used in the following ARIB standard link sequence.

FCM: Frame Control Message ACTC: Activation Channel BST: Beacon Service Table VST: Vehicle Service Table After that, setup information 1 is transmitted from the roadside apparatus to the vehicle-mounted apparatus, and thereafter, the setup is sequentially performed via the FCM. The information after the information 2 is transmitted from the roadside device to the vehicle-mounted device.

After the necessary information is transmitted, the in-vehicle device performs a setup process described later. As another example, the setup can be performed using various recording media such as the IC card 19 (or CD or DVD) instead of the road-vehicle communication.

In this case, as shown in FIG.
When the card 19 is connected to the IC card interface 17 of the vehicle-mounted device, power is supplied to the IC card 19 from the vehicle-mounted device. Next, the ATR is transmitted from the IC card 19 to the vehicle-mounted device.

Next, a select file setup signal is transmitted from the vehicle-mounted device to the IC card 19 in preparation for transmitting setup data. Next, when there is a response from the IC card 19, the in-vehicle device sends the IC card 19
Then, the read signal of the lead 1 is transmitted.

Next, according to the lead 1, the IC card 19
Transmits read data, which is data necessary for setup, to the in-vehicle device. Thereafter, according to leads 2 to n,
The read data is transmitted sequentially. Then, after the necessary information is transmitted, the in-vehicle device performs a setup process described later.

Next, the setup processing of FIG. 4 or 5 will be described in detail with reference to the flowchart of FIG. In step 100 of FIG. 6, it is determined whether there is communication (roadside communication) for requesting setup from the roadside apparatus to the in-vehicle apparatus. Here, if a positive determination is made, the process proceeds to step 120, while if a negative determination is made, step 1 is performed.
Go to 10.

In step 110, it is determined whether or not the IC card 19 or the like has been inserted into the vehicle-mounted device. If the determination is affirmative, the process proceeds to step 120, while if the determination is negative, the process returns to step 100. In step 120, it is determined whether or not there is a setup request by the communication or insertion of the IC card 19. Here, if the determination is affirmative, the process proceeds to step 130, while if the determination is negative, the process returns to step 100. .

That is, steps 100 to 120 are processes for monitoring whether there is a setup request due to road-vehicle communication or insertion of the IC card 19 or the like. Then, in step 130 where it is determined that there is a setup request, a setup screen as shown in FIG. 7A is displayed, for example.

In the following step 140, setting of functions and setting of private information are performed according to the application. Specifically, screens such as those shown in FIGS. 7B and 7C are displayed, and various function settings are made. Also, a screen shown in FIG. 8A is displayed so that private information can be input, and a screen as shown in FIG. 8B can be displayed to select whether or not to transmit private information. To Here, it may be possible to select whether or not to transmit, for each item of the private information. After the process in FIG. 8B, the selection process shown in FIG. 8C is performed.

At this time, if the private information has already been input to the vehicle-mounted device, the address and the name can be read out therefrom to reduce the trouble of inputting each time. In the following step 150, system information is set. In the setting of the system information, an application program including audio data, image data, a communication command table, and the like is downloaded. Further, an application ID code is written.

The application ID code is a code for identifying what kind of application this is, and is a code sent when communicating with the roadside device. FIG.
As shown in FIG. 3 (a), for a plurality of applications set by the user, the application I
By comparing D, it is possible to determine whether to start (move) or not (stop) the application. Also, it is possible to display and process only the information required by the user.

Therefore, while driving on a public road and looking for a gas station, it is not desirable to see the advertisement of the convenience store, but in such a case, the grouping by the application ID becomes possible. Next step 1
At 60, it is determined whether the setup has been completed. If the determination is affirmative, the process proceeds to step 170, whereas if the determination is negative, the process returns to step 130.

In step 170, the setup information is recorded in, for example, the EPPROM of the microcomputer, and the process is temporarily terminated. e) Next, the implementation state of the set up application will be described. As shown in FIG. 3, when the vehicle enters the communication area 39A of the XX burger 39, the OX set up as described above from the roadside apparatus to the in-vehicle apparatus.
A command to execute the application for the burger 39 is transmitted.

The vehicle receives the command and, for example,
The image shown in (a) is displayed on the display 25. Based on the display in this menu, the driver selects an order,
The switches 25a to 25e of the order number are pressed. For example, when "1. hamburger" and "4. coffee" are selected, after pressing the switches 25a and 25d of each number,
The decision switch 25f is pressed. As a result, since the order has been instructed, the content of the order is transmitted from the vehicle-mounted device to the roadside device.

After the transmission, the confirmation image shown in FIG. 9B is displayed. Next, in FIG. 9C, a selection screen for transmitting private information is displayed. Therefore, the driver determines whether to transmit the private information and presses the switch. Therefore, when “Yes” is selected, the private information is transmitted from the in-vehicle device to the roadside device, and is not transmitted when “No” is selected.

As described above, in this embodiment, the road-to-vehicle communication is performed between the vehicle and the store. At this time, it is determined whether the private information is transmitted to the store or the like by the driver of the vehicle. Etc. can be selected. Therefore, since there is no need to transmit private information when it is not desired to transmit the information, the security of the information can be enhanced. When transmitting private information, only specific items may be selected and transmitted.

Further, the menu screen may be held on the vehicle side, and all orders may be input in advance before arriving at drive-through. As a result, the drive-through can be used quickly. Here, the members' points in FIG. 9 will be described.

The member's points are for adding points according to the paid amount for a privilege (incentive) of the user. In this embodiment, it is conceivable that the point is stored in the vehicle-mounted device (for example, an IC card or a memory) or in the database of the roadside device.

In the former case, although the security is low, there is no need to transmit private information for confirming the identity to the roadside. In the latter case, the security is high,
Need to send private information. Therefore, each has advantages and disadvantages, and it is desirable to be able to select for each application. (Embodiment 2) Next, Embodiment 2 will be described, but description of the same parts as in Embodiment 1 will be omitted.

In this embodiment, as shown in FIG. 3, road-to-vehicle communication is performed between a vehicle and an ABC dealer 45 of a vehicle. Here, an in-vehicle device that has completed the setup shown in FIG. 10 will be described as an example. That is, as shown in the figure, at the time of setup, various settings such as whether or not to send private information are made.

A) First, road-vehicle communication in the dealer's customer management system will be described with reference to the timing chart of FIG. First, as shown in FIG.
When entering the communication area 45A of the BC dealer 45, AB
DSR between the roadside device of C dealer 45 and the vehicle-mounted device
ARIB mentioned above from FCM to VSC using C radio
Performs the link sequence determined by the standard.

When the link sequence is completed, the roadside device issues an application number (N
o.) is sent. The in-vehicle device identifies the application No. and executes the corresponding application.
Therefore, for example, the private information shown in FIG. 9 is read from the memory of the vehicle-mounted device, and the operation and transmission are performed according to the setting.

Next, the roadside device transmits a request for private information (personal information) to the vehicle-mounted device. Here, FIG.
As shown in (1), since the personal information is set to “not transmit”, the in-vehicle device transmits the non-transmission of the personal information to the roadside device.

Next, the roadside device transmits a vehicle information request to the vehicle-mounted device. Here, as shown in FIG.
Since “confirmation” is set, the driver is asked by the display 25 or by voice synthesis whether vehicle information can be transmitted.

At this time, if the driver selects "do not transmit", vehicle information not transmitted is transmitted to the roadside apparatus as shown in FIG. However, the confirmation process to the driver is a function that can be executed when the vehicle is stopped, and in the traveling state, the vehicle information unconfirmation may be transmitted to the roadside device unconditionally. Whether the vehicle is running can be determined using a vehicle speed signal, a wheel signal, a side brake signal, and the like. Since these signals are linked with the navigation, it is effective to link with the navigation.

Next, the roadside device requests a vehicle state request from the vehicle-mounted device. Here, as shown in FIG. 9, since the vehicle state information is set to “automatic”,
The vehicle state response is transmitted to the roadside device. Then, the roadside device searches the database and generates a corresponding message based on the information acquired as described above, and transmits screen information having the contents shown in FIG.

In this case, since the personal information is not sent, the database cannot be searched. Therefore, only the information shown in FIG. 12A is transferred and displayed on the display 25 of the vehicle. When the personal information is transmitted, the database can be searched and, for example, the screen information of FIG. 12B can be transmitted from the roadside device in addition to FIG. 12A.

On the vehicle side, the received information is displayed on the screen, and the communication area 45A of the ABC dealer 45 is displayed.
Within allows for mutual conversations. For example, from the roadside device, "Do you consider purchasing a new car today?", "Is it a maintenance check?", Etc. In response, the user sends the information to the roadside device by inputting a switch. By doing so, conversation is possible.

Also in this embodiment, whether or not to transmit private information to the dealer side can be selected by the driver, which is suitable for protecting the privacy of the driver. Further, since the set should be sent in advance what information, you can receive only the necessary service. (Embodiment 3) Next, Embodiment 3 will be described, but description of the same parts as in Embodiment 1 will be omitted.

In this embodiment, it is possible to set or change various applications registered in the vehicle-mounted device. As shown in FIG. 13, if the application's private setting screen is facilitated, the screen is displayed,
Various settings and changes can be made by inputting a switch.

For example, since “movable” is set for the application of the xx company 35, the xx company 3
When the vehicle enters the communication area 35A of No. 5, the application of the entrance / exit management operates by communication from the roadside device. In addition, since the application of the Iroha parking lot 43 is set to “stop”, even when the vehicle enters the communication area 43A of the Iroha parking lot 43 and is communicated from the roadside device, the parking fee by the credit is used. Automatic payment applications do not work.

As described above, for example, even when many applications are registered in the on-vehicle apparatus, the user can select any application to be activated, so that a process contrary to the intention is performed. Very convenient without any. Also, even when many communication areas are continuous, only a specific application operates, so that the image on the display 25 is easy to see, which is preferable.

It should be noted that the present invention is not limited to the above-described embodiment at all, and it goes without saying that the present invention can be implemented in various modes without departing from the present invention. (1) For example, in each of the above embodiments, the in-vehicle device has been described. However, the present invention is not limited thereto, and may be applied to a recording medium storing a unit for executing the above-described processing.

As the recording medium, an electronic control unit configured as a microcomputer, a microchip,
Various recording media such as a floppy disk, a hard disk, and an optical disk are included. That is, there is no particular limitation as long as it stores means such as a program that can execute the above-described processing of the in-vehicle device.

(2) The setup includes road-to-vehicle communication and I
It is possible to send data necessary for setting up the application to the vehicle side by using a recording medium such as a C card, a CD, or a DVD. For example, an address, a name, a credit number, etc.
The information may be read from a card or the like into the vehicle-side communication device.

(3) In the above-described embodiment, the user can select whether or not to transmit the private information. However, if necessary according to the law, a request from a public agency such as the police may be made. In some cases, private information may be transmitted (executing a specific application) regardless of the setting of whether to transmit private information (or whether to execute a specific application).
