  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The communication system according to the first embodiment of the present invention is configured as shown in FIG. As shown in the figure, the communication system 1 can be connected to a server device 10 connected to the Internet, and the server device 10 via a network such as the Internet and a predetermined mobile communication network (for example, a mobile phone communication network). The vehicle-mounted device 100 and the receiving device 200 are provided.

  The server device 10 is configured by a computer device having a communication function, collects information from the in-vehicle device 100, processes the information, and distributes information based on the processing result to the in-vehicle device 100 and the receiving device 200. The in-vehicle device 100 and the receiving device 200 have a navigation unit that supports vehicle driving such as route guidance to a destination, and are both mounted on the vehicle. Note that the in-vehicle device 100 is mounted on a vehicle that can be operated by selecting one of the manual operation mode and the automatic operation mode. The receiving device 200 is different from the in-vehicle device 100 in that it is mounted on a vehicle that does not support automatic driving, but the basic configuration is the same as that of the in-vehicle device 100, and the description of the configuration is omitted below. To do.

  The in-vehicle device 100 is configured as shown in FIG. In FIG. 2, the in-vehicle device 100 is configured by a computer unit (for example, including a CPU), and includes a processing unit 11 that executes various processes according to a program. The processing unit 11 includes an AV unit 17 capable of reproducing various sound sources and video sources (for example, CD, DVD, etc.), and a navigation unit 18 (navigation) that performs navigation processing such as route guidance to a vehicle destination. Device) is connected. Further, an output circuit 15 connected to the speaker 16 is connected to the processing unit 11, and an audio signal based on the processing of the AV unit 17 and the navigation unit 18 is output under the control of the processing unit 11. Is provided to the speaker 16 and the sound based on the audio signal is emitted from the speaker 16. Further, the processing unit 11 includes a storage unit 14 (for example, a hard disk drive) that stores various information such as music information and map information used in the AV unit 17 and the navigation unit 18, and an LCD. The display unit 13 is connected to an operation unit 12 that includes a touch panel on the display unit 13 and is used to input processing instructions and various information. Under the control of the processing unit 11, the display unit 13 is based on video from the AV unit 17, images such as maps and guide routes based on processing in the navigation unit 18, and information distributed from the server device 10 described above. Various information such as notification information is displayed.

  The in-vehicle device 100 includes a communication unit 19 that communicates with various devices that provide information, such as the server device 10 on the Internet, through a predetermined mobile communication network. Under the control of the processing unit 11, the communication unit 19 can communicate with the server device 10 that is an external device of the in-vehicle device 100 to transmit or receive various information.

  As described above, the vehicle on which the in-vehicle device 100 is mounted has a configuration capable of automatic driving, for example, steering while grasping the surrounding situation of the vehicle based on images obtained by a plurality of cameras, An automatic operation control device 300 that controls the operation of the accelerator and the brake is provided. By the operation control of the steering, the accelerator, and the brake by the automatic driving control device 300, traveling in the automatic driving mode not depending on the driving operation of the occupant is realized. The automatic driving control device 300 is in a state where it is operating effectively, i.e., in an automatic driving mode, and in a state where it is not operating effectively, i.e., normal driving in which the vehicle travels according to the driving operation of the occupant. A state signal representing any state of the (manual operation) mode is provided to the processing unit 11 of the in-vehicle device 100. The processing unit 11 can determine whether or not the driving mode of the vehicle has been switched based on the state signal from the automatic driving control device 300, and the type of switching (from the normal driving mode to the automatic driving). Whether the mode is switched to the normal operation mode or the automatic operation mode).

  In the communication system 1 configured as described above, the in-vehicle device 100 performs processing described below.

  After a switch operated when the vehicle starts, for example, an accessory switch (ACC) is turned on, a function for providing information to the server device 10 is activated in the in-vehicle device 100 (for example, activated in conjunction with ACC) Then, the processing unit 11 of the in-vehicle device 100 executes transmission processing according to the procedure shown in FIG.

  In FIG. 3, the processing unit 11 determines whether or not the vehicle operation mode has been switched based on the state signal input from the automatic driving control device 300 (S <b> 11). If the operation mode is not switched (NO in S11), the processing unit 11 maintains the current state (S12).

  In a situation where the operation mode is not switched (NO in S11), the processing unit 11 has a predetermined termination such as a condition that the ACC is turned off, a condition that the function of providing information to the server device 10 is terminated, or the like. While confirming that the condition is not satisfied (NO in S13), the current state is maintained (S12). In the process, when the driving mode is switched (YES in S11), the processing unit 11 generates mode switching position information as position information indicating the switching position of the driving mode (S14: vehicle side information generating means).

  As illustrated in FIG. 4, the mode switching position information has a configuration in which an operation mode switching position, a switching type, and a switching time are associated with each other. Specifically, the processing unit 11 controls the navigation unit 18, and the position where the switching is performed by the positioning function such as the GPS system of the navigation unit 18 (the position of the own device when the switching is performed). Information is acquired, and information indicating time such as the date and time when the switching is performed is acquired by a time measuring function. Note that the processing unit 11 acquires the information indicating the switching type by determining the state signal as described above.

  Next, the processing unit 11 controls the transmission function of the communication unit 19 to transmit the generated mode switching position information to the server device 10 that is an external device (S15: vehicle-side transmission means), and the process proceeds to S13. Move. Then, when the end condition is satisfied (YES in S13), the transmission process is ended. As described above, when the driving mode is switched for the vehicle, the in-vehicle device 100 generates the mode switching position information indicating the switching position of the driving mode, and transmits the generated mode switching position information to the server device 10. .

  The mode switching position information transmitted from the in-vehicle device 100 is processed in the server device 10 as follows. As shown in FIG. 5, when the server device 10 receives the mode switching position information by the communication function, the server device 10 accumulates the received mode switching position information in a storage device such as a database. As shown in FIG. 1, specifically, mode switching position information (mode switching position information transmitted by each of the plurality of in-vehicle devices 100) representing each position where the driving mode is switched for a plurality of vehicles is collected. Thus, big data is constructed (S21: collection means). And the server apparatus 10 analyzes the area with high switching frequency of the driving mode in a road or a lane based on this accumulated mode switching position information, and generates mode switching recommended position information as position information based on the analysis result ( S22: Server side information generating means). The recommended mode switching position information includes an area (area H) where the switching frequency of the driving mode is high in an area where the driving in the automatic driving mode is possible (an area where there is a track record of the automatic driving driving) as shown in FIG. This is information that can be discriminated from the other area (area L). In addition, it can be estimated that the area (area N) in which there is no actual switching of the operation mode is a place that does not support traveling in the automatic operation mode (an area that travels in the normal operation mode). The server device 10 transmits (distributes) the generated mode switching recommended position information to the in-vehicle device 100 and the receiving device 200 by a communication function (S23: server-side transmitting means). Thus, the server device 10 generates mode switching recommended position information based on the operation mode switching position, and distributes the mode switching recommended position information to the in-vehicle device 100 and the receiving device 200. Note that the server device 10 may have a configuration for publishing information based on this mode switching recommended position information on the web. Thereby, the mode switching recommended position information can be widely provided.

  The in-vehicle device 100 and the receiving device 200 execute notification processing for notifying information based on the distribution information. In the following, for simplification, the processing of the in-vehicle device 100 will be described, but the processing in the receiving device 200 is the same.

  After a switch operated when the vehicle starts, for example, an accessory switch (ACC) is turned on, a function for receiving provision of distribution information from the server device 10 is activated (for example, activated in conjunction with ACC) If good, the processing unit 11 of the in-vehicle device 100 executes notification processing according to the procedure shown in FIG.

  As illustrated in FIG. 7, the processing unit 11 controls the reception function of the communication unit 19 to acquire distribution information, that is, mode switching recommended position information from the server device 10 to acquire the information (S31). : Vehicle side receiving means). At this time, the processing unit 11 determines the reception status (S32), and if the mode switching recommended position information is received (YES in S32), if the previously acquired mode switching recommended position information exists. Then, the latest mode switching recommended position information is acquired by updating the information to the received information (S33).

  Then, after acquiring the latest recommended mode switching position information or when the recommended mode switching position information is not received (NO in S32), the processing unit 11 controls the navigation unit 18 to determine its own position. Acquired (S34), and compares the own machine position and the area (area H) with a high switching frequency in the mode switching recommended position information (S35). As a result of the comparison, the processing unit 11 determines whether or not a predetermined condition such that the position of the own machine has entered the area H or is within a predetermined distance to the area H is satisfied (S36). If it is determined that the predetermined condition is satisfied (YES in S36), the processing unit 11 controls the notification means such as the output circuit 15 and the speaker 16 and the display unit 13 as shown in FIG. Notification information indicating that the operation mode can be switched is notified. Specifically, the processing unit 11 notifies the person in the vehicle (for example, the driver) that the driving mode switching frequency is high, thereby recommending the switching of the driving mode (S37: Notification). means). Then, the processing unit 11 determines whether or not a predetermined termination condition such as a condition that the ACC is turned off and a condition that the function of receiving distribution from the server device 10 is terminated is satisfied (S38). If not satisfied (NO in S38), the process returns to S31. If satisfied (YES in S38), the notification process is terminated.

  According to the distribution system according to the first embodiment as described above, the in-vehicle device 100 can transmit the mode switching position information indicating the position where the operation mode is actually switched to the server device 10, and The server device 10 that receives the position information can be notified of the position where the operation mode is actually switched. The server device 10 can transmit mode switching recommended position information based on the collected plurality of mode switching position information to the in-vehicle device 100 and the receiving device 200. The in-vehicle device 100 and the receiving device 200 that receive the information can acquire the recommended mode switching position information based on the position where the operation mode is actually switched, and the acquired mode switching recommended position information Based on this, it is possible to notify the user that the operation mode can be switched. Specifically, the in-vehicle device 100 and the receiving device 200 that receive the information compare the area where the operation mode switching frequency represented by the received information is frequently compared with the position of the own apparatus, May be notified to the user that the frequency of switching the operation mode is high when a predetermined condition is met, such as when the vehicle overlaps or the position of the aircraft is within a predetermined distance from the area. it can. Thereby, the user can know in advance a place where the switching frequency of the driving mode is high, and thus can predict that the vehicle for switching the driving mode may be nearby. Since the user of the in-vehicle device 100 mounted on the vehicle that can be switched to automatic driving can know in advance the place where the switching frequency of the driving mode is high, the switching of the driving mode can be handled smoothly.

  Moreover, since it is the structure which has the server apparatus 10, the mode switching position information transmitted from the several vehicle-mounted apparatus 100 in the server apparatus 10 can be collected, and the mode switching recommended position information based on it can be produced | generated.

  In addition, since the in-vehicle device 100 transmits mode switching position information including type information indicating the switching type, the server device 10 that receives the information manually selects the type of operation mode switching, that is, the operation mode switching. It is possible to know whether the operation was switched from driving to automatic driving or from automatic driving to manual driving, and the position where automatic driving can be performed can be known. Thereby, it can be used for the road environment maintenance for making the driving environment which does not respond | correspond to automatic driving into a corresponding driving environment.

  Further, since the in-vehicle device 100 transmits mode switching position information including time information indicating the switching time, the server device 10 that receives the information can know the switching time of the operation mode, and according to the time. You can know the switching tendency of the operation mode.

  Further, the in-vehicle device 100 does not always transmit to the server device 10 whether the operation mode is the normal operation mode or the automatic operation mode, but transmits it when the operation mode is switched. Can be done efficiently.

  Next, a communication system according to the second embodiment of the present invention will be described. The communication system according to the second embodiment is configured as shown in FIG. The communication system 2 is different from the first embodiment in that communication (V2V: inter-vehicle communication) is directly performed between vehicles without using a server device.

  In other words, the communication system 2 includes the in-vehicle device 100 and the receiving device 200, and the in-vehicle device 100 and the receiving device 200 that are the other receiving sides from the in-vehicle device 100 that is the transmitting side where the operation mode is switched. The mode switching position information described above is transmitted via a predetermined network by a wireless LAN (Local Area Network) or the like. This transmission process is performed in the same procedure as in the first embodiment. Specifically, the in-vehicle device 100 transmits so that a vehicle whose distance from the own vehicle is within a predetermined distance is targeted. In the case of a road that is not face-to-face, transmission may be performed so that a vehicle that follows the rear of the own vehicle (including an oblique rearward of an adjacent lane) is targeted.

  The in-vehicle device 100 and the receiving device 200 on the receiving side receive the mode switching position information, compare the position represented by the received mode switching position information with the own device position, and compare the result as in the first embodiment. Is satisfied, that is, the position indicated by the mode switching position information is compared with the position of the own device, and the comparison result satisfies the condition), the fact that the operation mode can be switched is notified.
