Japanese Patent Laid-Open No. 2002-190092 (page 3, FIG. 4) JP 2002-286474 A (page 4, FIG. 3)

  In the thing of patent document 1, since the possibility of turning left and right is evaluated based on the driving history, when the driver does not have a land record, that is, when the driving history is hardly accumulated, the right or left turn The possibility is zero or very low. However, if the driver does not have a land record, the driver can easily make a sudden right / left turn, but the possibility of turning left / right is zero or extremely low. Gender was not consistent. That is, it is impossible for the user to ensure an appropriate distance between the host vehicle and the other vehicle.

  On the other hand, in the thing of patent document 2, since the timings, such as a break guide, differ only according to driving | running | working frequency, it can make a user ensure the appropriate distance of the own vehicle and other vehicles. could not.

  A data processing apparatus according to the present invention is a data processing apparatus that calculates a land survey using travel history data, and includes a communication control unit that transmits land survey data corresponding to the evaluation of the land survey to a communication device. Is. The interpretation of the lexical terms in the present invention is as follows.

  The “running history data” is a concept including past position data and time data associated with the past position data.

  “Evaluation of land guide” is a concept that includes alternative evaluation for land guide and numerical evaluation for land guide. An example of “an alternative evaluation for a land guide” is whether or not there is a land guide. As an example of “numerical evaluation of a land guide”, there is a land guide level 10 or the like.

  “Determining” is a concept including an operation and a lookup table.

  The “communication device” is a concept including a device for communication via a public line and a device for communication not via a public line. An example of “communication via a public line” is the Internet. On the other hand, as an example of “communication not via a public line”, there is so-called DSRC (narrow band wireless communication).

  The data processing apparatus according to the present invention is a data processing apparatus that receives data transmitted on the other vehicle side, and outputs a guide relating to the evaluation of the land inspection corresponding to the land inspection data transmitted on the other apparatus side. And an output control unit for outputting the output. The interpretation of lexical terms in the present invention is different from the above-described interpretation of lexical terms as follows.

  “Transmitted on the other device side” is a concept including transmission via a public line and transmission not via a public line, and the source of data may be any other device.

  “Guidance” is a concept that includes a voice, an image, a light, and a vibration.

  The “output unit” is a concept including a speaker, a display, a light, and a vibrator.

  The data processing device according to the present invention is a data processing device that receives data transmitted on the other vehicle side and obtains evaluation of the land identification using the travel history data, and the land identification data transmitted on the other device side. If the evaluation of the land guide corresponding to is less than or equal to the evaluation of the land guide obtained by the own device, it is provided with an output control section for outputting the attention guidance corresponding to the attention guidance data stored in the storage medium to the output section. is there. The interpretation of lexical terms in the present invention is different from the above-described interpretation of lexical terms as follows.

  As an example of “if below”, equivalent and more negative evaluations are applicable if the evaluation of land records is alternative. On the other hand, if the evaluation of the land cover is numerical, the same and lower evaluations are applicable.

  The “attention guidance” is sufficient if it is a starting point for the user to ensure an appropriate distance between the host vehicle and the other vehicle.

  The data processing device according to the present invention is a data processing device that receives data transmitted on the other vehicle side, and the speed of the vehicle according to the evaluation of the land image corresponding to the land image data transmitted on the other device side. The vehicle control part which controls is provided. The interpretation of lexical terms in the present invention is different from the above-described interpretation of lexical terms as follows.

  As an example of “controlling the speed of the vehicle according to the evaluation of the land record”, if the evaluation for the land record is alternative, the speed of the vehicle decreases if the evaluation of the land record is negative. On the other hand, if the evaluation of the land record is numerical, the vehicle speed decreases as the evaluation of the land record becomes negative.

  The data processing apparatus according to the present invention is a data processing apparatus that receives data transmitted on the other vehicle side, and seeks evaluation of the land records of others using the travel history data transmitted on the other vehicle side, The output control part which makes the output part output the guidance which concerns on the said land pick-up is provided. The interpretation of the lexical terms in the present invention is as described above.

  The present invention has an effect that the user can be ensured an appropriate distance between the own vehicle and the other vehicle since the evaluation of the land guide relating to one vehicle is used by another vehicle.

Hereinafter, the best mode for carrying out a data processing apparatus according to the present invention will be described with reference to FIGS.
<Overall Configuration> The overall configuration of the inter-vehicle communication system 1 according to the present embodiment will be described with reference to FIG. The vehicle 1a and the vehicle 1b following the vehicle 1a include a navigation device 10a and a navigation device 10b, respectively. The navigation device 10a and the navigation device 10b perform data communication by DSRC or the like. In the following description, it is assumed that the user of the vehicle 1a has a land record for area A and does not have a land record for area B.
<Device Configuration> The configuration of the navigation device 10 according to the present embodiment will be described with reference to FIG. The navigation device 10 is stored in an input interface (hereinafter referred to as an input IF) 11 for inputting various data, an HDD 12 for storing various programs and various data, a ROM 13 for storing basic programs, an HDD 12 and a ROM 13 and the like. CPU 14 (corresponding to “output control unit”, “communication control unit”, “vehicle control unit” and “control unit”) that interprets and executes the program, RAM 15 that holds data from the input IF 11, CPU 14, etc., An audio processor 16 that controls audio output in accordance with data from the CPU 14, an image processor 17 that controls image output in accordance with data from the CPU 14, a VRAM 18 that holds image data, and an output interface that outputs various data ( (Hereinafter referred to as output IF) 19 and for DSRC And a signal unit 20, which are connected by a bus.

  The input IF 11 includes a GPS receiver 21 that receives GPS data from a satellite, an azimuth sensor 22 that outputs azimuth data corresponding to the azimuth, a speed sensor 23 that outputs speed data corresponding to the velocity, and an object. A touch panel (corresponding to an “operation unit”) 24 that outputs data related to contact coordinates in response to the contact is connected.

  In addition to the navigation program, the HDD 12 sends a communication control unit that asks the communication device to transmit the land inspection data corresponding to the evaluation of the land inspection by using the travel history data, and is transmitted from the other device side. A program for causing the CPU 14 to function as an output control unit that causes the output unit to output guidance relating to the evaluation of the land record corresponding to the land record data and the evaluation of the land record obtained by the own device is stored. Further, the HDD 12 stores travel history data in which the position, date, and time are associated, guidance voice and guidance data corresponding to the guidance image (corresponding to “attention guidance data”), and the like.

Connected to the output IF 19 are a speaker 31 (corresponding to “guidance unit”) that outputs sound corresponding to the audio data and a display 32 (corresponding to “guidance unit”) that displays an image corresponding to the image data. Has been. The display 32 is located on the back surface of the touch panel 24 so that the contact coordinates of the touch panel 24 coincide with the display coordinates of the display 32.
<Transmission Processing> The operation of the navigation device 10 configured as described above will be described with reference to FIGS. As shown in FIG. 3, in the navigation device 10a provided in the vehicle 1a, the CPU 14 expands the program stored in the HDD 12 in the RAM 15 and executes the following processing.

  The CPU 14 calculates the travel time T using the travel history data stored in the HDD 12 (step S1). The travel history data (see FIG. 4A) is organized for each user, and further organized for each region using position elements. For each region, the sum of time is calculated to obtain the travel time (see FIG. 4B). In the present embodiment, it is assumed that the travel time of the vehicle 1a is 350 hours in the region A and 6 hours in the region B.

  When the travel time T is calculated in step S1, the CPU 14 determines whether or not the travel time T is larger than the threshold value α (step S2). In the present embodiment, it is assumed that threshold value α is 100 hours.

  When it is determined in step S2 that the traveling time T is greater than the threshold value α (Yes in S2), the CPU 14 sets the land record data to “1” (step S3). “Landbook data = 1” means that there is a landbook.

  On the other hand, when it is determined in step S2 that the traveling time T is equal to or less than the threshold value α (No in S2), the CPU 14 sets the land record data to “0” (step S4). “Landbook data = 0” means that there is no landbook.

When the land record data is obtained in step S3 or step S4, the CPU 14 transmits the land record data D1a to the communication device 20 (step S5). In the present embodiment, since the DSRC format is used as the communication method, the format of the land record data is also adapted to the DSRC format.
<About Guidance Processing> The operation of the navigation device 10 configured as described above will be described with reference to FIGS. As shown in FIG. 5, in the navigation device 10b provided in the vehicle 1b, the CPU 14 expands the program stored in the HDD 12 in the RAM 15 and executes the following processing. This process is started by using the land inspection data D1a transmitted by the navigation device 10a as an interrupt signal.

  The CPU 14 determines whether or not the land record data D1a transmitted by the navigation device 10a is “0” (step S11). The land record data D1a is transmitted by the navigation device 10a, then received by the navigation device 10b, and held in the RAM 15.

  When it is determined in step S11 that the land record data D1a is “0” (Yes in S11), the CPU 14 outputs a guidance indicating that there is no land record to the speaker 31 or the display 32 (step S12). ). Specifically, when the fact that there is no land record is output by voice, the voice processor 16 receives the control data from the CPU 14, reads the guidance data corresponding to the guidance that there is no land record from the HDD 12, and reads the land record. A sound indicating that there is no sound is output to the speaker 31. On the other hand, when an image indicating that there is no land record is output, the image processor 17 receives the control data from the CPU 14 and expands the guide data corresponding to the guide indicating that there is no land record from the HDD 12 to the VRAM 18. A guide image indicating that there is no signature is output to the display 32 (see FIG. 6A).

  On the other hand, if it is determined in step S11 that the land record data D1a is not “0” (No in S11), that is, if it is determined that the land record data D1a is “1”, the CPU 14 A guidance to the effect that there is a land record is output to the speaker 31 or the display 32 (step S13).

  When the guidance is output in step S12 or step S13, the CPU 14 determines whether or not the land record data D1b is held in the RAM 15 (step S14). Here, the land record data D1b is data obtained in the navigation device 10a, and is data corresponding to the evaluation of the land record related to the vehicle 1b.

  When it is determined in step S14 that the land record data D1b is held in the RAM 15 (Yes in S14), the CPU 14 determines whether or not the land record data D1b held in the RAM 15 is “0”. (Step S15).

  If it is determined in step S15 that the land record data D1b is “0” (Yes in S16), the CPU 14 causes the speaker 31 or the display 32 to output guidance indicating that there is no land record (step S16). ). Specifically, when the fact that there is no land record is output by voice, the voice processor 16 receives the control data from the CPU 14, reads the guidance data corresponding to the guidance that there is no land record from the HDD 12, and reads the land record. A sound indicating that there is no sound is output to the speaker 31. On the other hand, when an image indicating that there is no land record is output, the image processor 17 receives control data from the CPU 14 and expands guide data corresponding to the guide indicating that there is no land record from the HDD 12 to the VRAM 18. A guide image indicating that there is no signature is output to the display 32 (see FIG. 6B).

On the other hand, if it is determined in step S15 that the land record data D1b is not “0” (No in S15), that is, if it is determined that the land record data D1b is “1”, the CPU 14 A guidance to the effect that there is a land record is output to the speaker 31 or the display 32 (step S17).
<Effects in the present embodiment> As described above, according to the present embodiment, since the evaluation of the land record obtained by the vehicle 1a is guided by the subsequent vehicle 1b, the vehicle 1a and the vehicle 1b are appropriately selected for the user. A long distance can be secured.

For example, in the region A, since the evaluation of the land record obtained by the vehicle 1a is affirmative and it is unlikely that the vehicle 1a will make a sudden lane change, the user of the vehicle 1b You do n’t have to be so conscious. Moreover, since the user of the vehicle 1a is highly likely to be familiar with the escape route, the user of the vehicle 1b may follow the vehicle 1a in order to avoid a traffic jam. On the other hand, in the region B, since the evaluation of the land record obtained by the vehicle 1a is negative and there is a high possibility that the vehicle 1a will make a sudden lane change, the user of the vehicle 1b is the distance between the vehicle 1a and the vehicle 1a. It is sufficient to ensure sufficient.
<Other Embodiment 1> As another Embodiment 1, the HDD 12 asks the HDD 12 to evaluate the land record using the travel history data, and transmits the land record data transmitted on the other device side (for example, the navigation device 10a). CPU 14 as an output control unit that outputs guidance for calling attention to the speaker 31 or the display 32 if the evaluation of the land record corresponding to is less than or equal to the evaluation of the land record obtained by the own device (for example, the navigation device 10b). A program for functioning is stored. The HDD 12 stores guidance data corresponding to guidance for calling attention. Specifically, if the land inspection data D1a obtained by the navigation device 10a is “0” and the land inspection data D1b obtained by the navigation device 10b is “0” or “1”, the vehicle 1a. In the vehicle 1b following this, a guidance for calling attention is output (see FIG. 6C).

According to this embodiment, if the evaluation of the land guide obtained by the vehicle 1a is equal to or less than the evaluation of the land guide obtained by the vehicle 1b, a guidance for alerting is output. An appropriate distance between the vehicle 1a and the vehicle 1b can be ensured.
<Other Embodiment 2> As another embodiment 2, the HDD 12 stores the vehicle 1b according to the evaluation of the land record corresponding to the land record data transmitted on the other device side (for example, the navigation device 10a). A program for causing the CPU 14 to function as a vehicle control unit that controls the speed is stored. Specifically, it is determined whether or not the land identification data obtained by the navigation device 10a is “0”. If the land identification data is “0”, a signal for reducing the speed of the vehicle 1b is generated. Is output.

According to this embodiment, if the land survey obtained by the vehicle 1a is negative, a signal for reducing the speed of the vehicle 1b is output, so the vehicle 1a and the vehicle 1b An appropriate distance can be automatically secured.
<Other Embodiment 3> As another Embodiment 3, the HDD 12 is requested to evaluate the land records of others using the travel history data transmitted on the other vehicle side (for example, the navigation device 10a). A program for causing the CPU 14 to function as a control unit that causes the speaker 31 or the display 32 to output guidance related to the evaluation of the land record is stored. Specifically, the process of step S1 thru | or step S5 should just be performed with the navigation apparatus 10b.

According to this embodiment, since the land inspection for each vehicle is all evaluated by one apparatus, it is possible to use the same evaluation standard.
<Modification> It goes without saying that the present invention is not limited to this embodiment, and various modifications can be considered. In the above embodiment, the evaluation of the land record is an alternative of “Yes” or “No”, but numerical evaluation such as “Level 3” may be used.

  In the above embodiment, the land record data is directly transmitted and received between the vehicle 1a and the vehicle 1b. However, a method of transmitting and receiving via a public line may be used.

  As described above, the present invention has an effect that the user can ensure an appropriate distance between the host vehicle and the other vehicle, and is useful as a navigation device or the like.
