BACKGROUND OF THE INVENTION
The present invention relates to a vehicle information providing method in which an in-vehicle terminal mounted on a vehicle provides information to a user.
[0002]
[Background Art and Problems to be Solved by the Invention]
2. Description of the Related Art Conventionally, in a vehicle, a driver can listen to a baseball broadcast, a soccer broadcast, and the like on a vehicle-mounted television, a radio, and the like while driving. However, depending on the driver or the driving situation, there is a case where it is only necessary to know only the game progress information instead of such relay.
[0003]
In such a case, it is conceivable that “information that the user wants to know” is sequentially received from the outside and provided to the user. For example, in a mobile phone, by registering in advance in the information center, news bulletins and the like are automatically transmitted to the mobile phone, and the user can obtain information he wants to know.
[0004]
However, according to this method, information is only unilaterally transmitted from the information center to the mobile phone. If the information to be provided is information on the progress of a game in baseball and soccer, the user can know the progress of the game by information periodically transmitted from the information center. However, depending on the user, there is a change in the progress of the game. You may want to know the information at the time, and you may want to see scoring scenes such as baseball home run scenes or soccer goal scenes when the game progress changes.
[0005]
Such a scoring scene is transmitted as video information. However, in the case of a vehicle, the driver cannot view the video even if the video information is reproduced during driving.
[0006]
The present invention has been made in view of the above problems, and the information that the user of the vehicle wants to know can be acquired by the user when there is a change in the information. The first object is to enable acquisition of video information.
[0007]
A second object is to allow the user to view the video even when the video information is received during driving.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the invention according to claim 1 is a vehicle information providing method in which an in-vehicle terminal mounted on a vehicle provides information to a user,
Send a request to start sending information to the information center,
In response to the information transmission start request, the information center receives information transmitted about items registered in the information center in advance to the user, and provides the information to the user.
Receiving new information sent by the information center when there is a change in the information, and providing the new information to the user;
When the information transmitted by the information center includes an inquiry about whether to request reception of video information related to the information, the video information is received when it is detected that the user wants to receive the information. Send an answer to the information center,
The video information transmitted by the information center in response to the video information transmission request is received and the video information is reproduced.
[0009]
According to the present invention, the information that the user of the vehicle wants to know can be acquired by the user when there is a change in the information, and when there is video information, the video information is acquired in response to the user's request. be able to.
[0010]
In this case, as in the invention described in claim 2, if the in-vehicle terminal determines the stop state of the vehicle and reproduces the received video information, the video information is received during driving. The user can view the video.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments shown in the drawings will be described below. FIG. 1 shows a configuration of a vehicle navigation device as an in-vehicle terminal.
[0015]
The navigation device has a position detector 1 for detecting the current position of the vehicle. The position detector 1 includes a geomagnetic sensor 2, a gyroscope 3, a distance sensor 4, and a GPS receiver 5. The navigation device includes a map data input device 6 that reads map data from a map data storage medium (map data storage means) 6a such as a CDROM-ROM or DVD-ROM, and operation switches for performing various operations necessary for navigation. Group 7, a control circuit (control means) 8 that executes various processes necessary for navigation, a display device 9 that displays a map, a sound generator 10 that generates sound, and a signal from a remote controller 12 are received. Remote control sensor 11, voice recognition device 13 that recognizes the voice of a user (occupant such as a driver), communication device 14 that communicates with information center 20, and the like.
[0016]
This navigation device has a function of reading out map data from the map data storage medium 6a and performing travel guidance based on the read map data and the current position of the vehicle (this travel guidance includes route guidance for the destination). A function of communicating with the information center 20, receiving information transmitted by the information center 20 for items registered in advance in the information center 20, and providing the information to the user using display and voice. Have.
[0017]
The information center 20 includes a communication device for communicating with the navigation device of each vehicle and other in-vehicle terminals, a data processing unit for generating data to be provided to the user using a computer, and analyzing the user's request. ing.
[0018]
Hereinafter, a method of providing information to the user by communicating with the information center 20 will be described with reference to the flowcharts shown in FIGS. Before providing this information, the user registers “information to know” in the information center 20. For this registration, for example, the information center 20 is contacted by telephone, and information necessary for identifying the user, items of information to be known (for example, the month / day / day / day / giant game progress) are registered. . Alternatively, when the user inputs information necessary for the above registration using the screen of the display device 9 in the navigation device, the information may be transmitted from the communication device 14 to the information center 20 for registration.
[0019]
When the vehicle equipped with this navigation device starts its operation, the control circuit 8 determines the vehicle operation start based on a signal from an ignition switch (not shown) (step 101). A request for information transmission start (for example, “operation start” information) is transmitted to the information center 20 (step 102). This information transmission start request includes information necessary to identify the user.
[0020]
Upon receiving the information transmission start request, the information center 20 identifies a user based on the request, identifies an item registered in advance by the user, and transmits information to be provided for the item. This transmission information is composed of character data for screen display, voice data for voice generation, and the like.
[0021]
When the communication device 14 of the navigation device receives the information transmitted from the information center 20, the control circuit 8 analyzes the information and uses the display by the display device 9 and the sound generation by the sound generation device to convert the received information. Provide to the user (step 103). In this case, the received information is displayed on a part of the navigation screen of the display device 9 (for example, as shown in FIG. 4A, the Chunichi vs Giant 1-2 is displayed), and from the sound generation device, for example, , “Giant, finishes the back of five Sino-Japanese wars.
[0022]
Further, when the information transmitted by the information center 20 includes an inquiry as to whether reception of video information related to the information is requested or not (step 104), the reception of the video information from the sound generator is performed. Is generated asking whether or not to request (step 105). For example, the voice of “There is a home run scene but do you want to receive it?” Is generated. When a voice (for example, “Yes”) that the user wants to receive the voice is generated and the voice recognition device 13 recognizes the voice, the control circuit 8 receives the recognition signal from the voice recognition device 13. In response, it detects that the user wants to receive the video information (step 106), and sends a response to the video center to the information center 20 (step 107).
[0023]
When the information center 20 transmits the video information in response to this answer, the communication device 14 receives the video information (step 108). After determining the reception, the control circuit 8 determines whether or not the vehicle is stopped (step 109). Whether or not the vehicle is in a stopped state can be determined based on the vehicle speed obtained based on the signal from the distance sensor 4 or the vehicle speed obtained based on the signal from the GPS receiver 5. it can. When the vehicle is stopped, the received video information is reproduced (that is, an image is displayed on the display device) (step 110). For example, if the video information is a home run scene, the moving image of the home run scene is displayed on the display device 9 instead of the navigation screen.
[0024]
Thereafter, the control circuit 8 enters a reception waiting state and executes the processing shown in FIG. In the information center 20, the latest information on various items registered by the user is input to the computer of the information center 20. And if there is a change in the information of the above-mentioned user registration items (for example, Sino-Japanese x Giant game progress), the information center 20 transmits the new information.
[0025]
When the communication device 14 of the navigation device receives new information transmitted from the information center 20, the control circuit 8 analyzes the information and displays the received new information on a part of the navigation screen of the display device 9. (For example, as shown in FIG. 4 (b), the Chunichi vs Giant 3-2 is displayed), and from the voice generator, for example, “3 times 2 and 3 giants won in 3 runs of 6 back XX. Is generated (step 111). Further, when it is determined that the new information includes an inquiry as to whether or not to request the reception of video information related to the information (step 112), whether or not the audio generation device requests reception of the video information. A questioning voice is generated (step 113). For example, the voice of “There is a home run scene but do you want to receive it?” Is generated. When the user generates a voice indicating that the user wants to receive it and the voice recognition device 13 recognizes the voice, as described above, the control circuit 8 sends a response indicating that the video information is received to the information center. The video information transmitted in response to the answer from the information center 20 is received, the stop state of the vehicle is determined, and the video information, for example, the video of the home run scene is displayed on the display device (step 113). ~ 118).
[0026]
Thereafter, the above-described processing is repeated every time there is a change in information about items registered in the information center 20 by the user.
[0027]
Then, when the vehicle stops operating, the control circuit 8 ends the above processing.
[0028]
In the above-described embodiment, the vehicle navigation device is used as the vehicle-mounted terminal, but a vehicle-mounted terminal different from the vehicle navigation may be used.
[0029]
Also, although the voice recognition device 13 is used to detect the user's response to the question of whether to request the reception of video information, the user's response is detected by other means such as an operation switch. May be.
[0030]
Further, when the information center 20 can transmit the video information, the video information may be transmitted to the in-vehicle terminal without inquiring the in-vehicle terminal about the reception request. In this case, the video information is reproduced after determining the stop state of the vehicle, as in the above-described embodiment.
