The apparatus of Patent Document 1 registers points by distinguishing the traveling direction, and determines whether or not to reproduce the utterance content by distinguishing the traveling direction.

JP 2001-141498 A

  The device of Patent Document 1 is a device that reproduces registered utterance content when the host vehicle approaches a registered point. Since an unexpected event such as a puncture of another vehicle in front of the host vehicle cannot be registered in advance, the technique disclosed in Patent Document 1 transmits the unexpected event to the vehicle occupant. I can't.

  In recent years, it has become possible to share information in real time using a portable terminal. If information is transmitted using this portable terminal, a sudden event can be transmitted to the surroundings in real time.

  However, in the case of information transmission by a portable terminal, it is difficult to limit the area where information is transmitted. On the other hand, the vehicles that need information that a sudden event has occurred on the road and its surroundings are only vehicles that exist around the point where the sudden event has occurred.

  More precisely, information that the sudden event has occurred is necessary only for the vehicle traveling in the lane in the same traveling direction as the lane where the sudden event has occurred and going to the point where the sudden event has occurred. .

  Therefore, if information indicating that a sudden event has occurred is transmitted using the mobile terminal, there is a problem that information indicating that a sudden event has occurred is reported even in a vehicle that does not require the information.

  The present invention has been made based on this circumstance, and the purpose of the present invention is to suppress information indicating that a sudden event has occurred from being notified by a vehicle that does not require the information. On the other hand, there are provided a vehicle information transmission device, a vehicle information transmission system, and a vehicle information notification device that can prevent a vehicle that needs information from being notified of the information.

  The above object is achieved by a combination of the features described in the independent claims, and the subclaims define further advantageous embodiments of the invention. Further, the reference numerals in parentheses described in the claims indicate the correspondence with the specific means described in the embodiments described later as one aspect, and limit the technical scope of the present invention. is not.

  An invention relating to a vehicle information transmitting apparatus for achieving the above object includes an event input unit (16, 17) used by a vehicle to input event specifying information for specifying an unexpected event to be registered by a vehicle occupant. The direction input unit (16, 17) in which the occupant inputs a notification direction, which is a direction to notify that a sudden event has occurred, and the sudden event specified by the event specifying information indicate that a sudden event has occurred. A transmission process in which event occurrence information is transmitted from the transmission unit by performing a direction limitation process for limiting the direction in which the event occurrence information is notified by an information notification device used in another vehicle to the notification direction input from the direction input unit. Part (S8B, S8C, S9, 9A, 9B).

  According to the present invention, event occurrence information indicating that a sudden event has occurred is transmitted from the transmission unit. However, the event occurrence information is transmitted by performing a direction limiting process for limiting the direction in which the event occurrence information is notified by the information notification device used in the other vehicle to the notification direction input from the input unit. And this direction limitation process is a process which limits the direction which alert | reports event occurrence information to the alerting | reporting direction which the passenger | crew input from the input part.

  For example, an occupant who has seen a sudden event determines that the sudden event only needs to be reported to the rear of the vehicle on which the occupant is riding, and the direction in which the occupant is behind the vehicle on which the occupant is riding is reported. Let us consider a case where a direction is input from the direction input unit. In this case, the direction in which the event occurrence information is notified is limited to the rear of the vehicle on which the occupant is riding by the direction limiting process.

  Thus, since the direction in which the event occurrence information is notified is limited to the notification direction input by the occupant, event occurrence information indicating that a sudden event has occurred is notified by a vehicle that does not require that information. It is also possible to prevent the information from being notified in a vehicle that needs information while suppressing the above.

  An invention relating to a vehicle information transmission system for achieving the above object includes a vehicle information transmission system (1) including the vehicle information transmission device and a server device (20) installed outside the vehicle. The server device receives the event occurrence information transmitted by the vehicle information transmission device, and the notification period for setting the notification period of the event occurrence information received by the server side reception unit. A setting unit (S36) and a server side transmission unit (21b) for transmitting event occurrence information during the notification period set by the notification period setting unit are provided.

  In addition, the invention relating to the vehicle information notification device for achieving the above object includes the vehicle information transmission device, a receiving unit (12, 13) for receiving event occurrence information transmitted from the outside of the vehicle, And an informing unit (15, 18) for informing the event specifying information received by the receiving unit.

<First Embodiment>
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a vehicle information notification system 1 including an in-vehicle device 10 having a function as a vehicle information notification device of the present invention. In addition, this vehicle information alerting | reporting system 1 is equipped with the function as a vehicle information transmission system of a claim.

  The vehicle information notification system 1 includes a server device 20 in addition to the in-vehicle device 10. The in-vehicle device 10 and the server device 20 can communicate with each other via the public communication line network 30. Moreover, if the other vehicle equipment 10 exists in the communicable range of the near field communication part 12 shown in FIG. 2, the vehicle equipments 10 can communicate with each other using the near field communication part 12. .

  For convenience of explanation, one vehicle shown in FIG. 1 is a first vehicle C1, the other vehicle is a second vehicle C2, the in-vehicle device 10 mounted in the first vehicle C1 is an in-vehicle device 10A, and the second vehicle. The in-vehicle device 10 mounted on C2 is referred to as an in-vehicle device 10B. When it is not necessary to distinguish between the first vehicle C1 and the second vehicle C2, it is referred to as a vehicle C. Further, when it is not necessary to distinguish between the in-vehicle devices 10A and 10B, they are described as the in-vehicle device 10.

  As shown in FIG. 2, the in-vehicle device 10 includes a storage unit 11, a short-range communication unit 12, a wide-area communication unit 13, a position detection unit 14, a display unit 15, a touch panel 16, a microphone 17, a speaker 18, and an ECU 19. .

  The storage unit 11 stores road map data, event identification information, and notification required types. The event specifying information is information for specifying an unexpected event such as a puncture or an accident. The process of storing the event specifying information in the storage unit 11 will be described later with reference to FIG.

  The notification required type is a type of event specifying information that needs to be notified. The type of event specifying information is set in advance. For example, this type includes traffic jam information, enforcement information, accident information, and the like. The notification required type is set based on a user operation performed in a state where the list of event specifying information is displayed on the display unit 15.

  The short-range communication unit 12 performs inter-vehicle communication with the short-range communication unit 12 mounted on another vehicle using radio waves in a predetermined frequency band such as a 5.8 GHz band and a 700 MHz band. The short-range communication unit 12 performs road-to-vehicle communication with a short-range communication unit provided in a roadside device installed on the roadside.

  The wide area communication unit 13 communicates with the wide area communication unit 21 included in the server device 20 using the public communication line network 30. In this embodiment, communication between the wide area communication unit 13 and the server device 20 is also performed by unicast. The wide-area communication unit 13 receives event occurrence information transmitted from the vehicle-mounted device 10 used in other vehicles and temporarily stored by the server device 20 from the server device 20. The wide area communication unit 13 corresponds to a transmission unit and a reception unit in claims.

  The position detection unit 14 sequentially detects the current position of the host vehicle. For example, the position detection unit 14 includes a GNSS receiver that receives radio waves from a satellite included in a GNSS (Global Navigation Satellite System). Based on the signal received by the GNSS receiver, the current position is detected.

  The display unit 15 includes a display screen, and a road map around the current position is displayed on the display screen. The display unit 15 corresponds to a notification unit. The touch panel 16 is provided as an event input unit and a direction input unit, and is stacked on the display screen of the display unit 15. The touch panel 16 may be a capacitance type or a pressure sensitive type. The microphone 17 is also equivalent to an event input unit, and detects the voice spoken by the occupant and converts it into an electrical signal. The speaker 18 outputs event occurrence information indicating that a sudden event has occurred. The speaker 18 also corresponds to the notification unit.

  The ECU 19 is a computer including a CPU, a ROM, a RAM, and the like, and the CPU executes various functions by executing a program stored in the ROM while using a temporary storage function of the RAM.

  For example, the current position detected by the position detection unit 14 is sequentially transmitted to the server device 20 using the wide-area communication unit 13 and transmitted to the surroundings of the host vehicle using the short-range communication unit 12. The processing shown in FIGS. 4 and 8 is also executed. Note that some or all of the functions executed by the ECU 19 may be configured in hardware by one or a plurality of ICs.

  The ECU 19 can communicate with other ECUs mounted on the same vehicle via the in-vehicle LAN 50. Also, various sensor signals such as a vehicle speed signal detected by the vehicle speed sensor can be acquired via the in-vehicle LAN 50.

  Next, the configuration of the server device 20 will be described with reference to FIG. As illustrated in FIG. 3, the server device 20 includes a wide area communication unit 21 and a control unit 22. The wide area communication unit 21 includes a reception unit 21a and a transmission unit 21b. The wide area communication unit 21 has the same function as the wide area communication unit 13 included in the in-vehicle device 10. The receiving unit 21 a receives information transmitted by the wide area communication unit 13 of the in-vehicle device 10 via the public communication line network 30, and the transmission unit 21 b receives the wide area communication of the in-vehicle device 10 via the public communication line network 30. Information is transmitted to the unit 13. The receiving unit 21a and the transmitting unit 21b correspond to a server-side receiving unit and a server-side transmitting unit in claims.

  Next, among the processes executed by the ECU 19 of the in-vehicle device 10, a process for transmitting speech data will be described with reference to FIG. The ECU 19 repeatedly executes the process shown in FIG. 4 at a preset cycle. The description of FIG. 4 will be described using the in-vehicle device 10A mounted on the first vehicle C1 as an example.

  In step S1, it is determined whether or not a registration start operation has been performed. Various specific operations can be set as the registration start operation. For example, in a state where the registration start button is displayed on the display unit 15, the operation corresponding to the registration start button on the touch panel 16 is set as the registration start operation. Alternatively, a registration start operation may be performed by inputting a predetermined message instructing the start of registration from the microphone 17.

  For example, as shown in FIG. 5, the occupant of the first vehicle C1 is punctured when the first vehicle C1 passes next to a vehicle with punctured wheels (hereinafter, punctured vehicle) Cp. When the existence of Cp is known, a registration start operation is performed.

  If the determination in step S1 is NO, the process in FIG. 4 is terminated. If judgment of step S1 is YES, it will progress to step S2. In step S <b> 2, a message requesting an utterance explaining the sudden event is output from the speaker 18. Further, the message may be displayed on the display unit 15.

  In step S3, utterance data, which is voice data uttered by the occupant in response to the request for utterance in step S2, is stored in the storage unit 11. In the example of FIG. 5, the passenger speaks, for example, “There is a punctured vehicle”. In this case, “there is a punctured vehicle” spoken by the occupant is stored in the storage unit 11 as speech data as it is. This utterance data is information that can specify that the sudden event is an event that a punctured vehicle exists, and corresponds to the event specifying information in the claims.

  In step S4, a direction designation screen is displayed on the display unit 15. The direction designation screen is a screen that displays the current position of the first vehicle C1 and the surrounding road map. If this road map is already displayed, the process of step S4 can be omitted. FIG. 6 illustrates a direction designation screen. In FIG. 6, reference numeral 40 denotes a vehicle position mark.

  In step S5, it is determined whether or not there has been a direction designation operation for designating the notification direction. The direction specifying operation in the first embodiment is an operation of tracing the road map displayed on the display unit 15 with an operating body such as a finger. In the following description, it is assumed that the operating body is a finger.

  In FIG. 6, the traced range and direction are illustrated by dashed arrows. In FIG. 6, the road where the vehicle position mark 40 is located is traced backward in the traveling direction, starting from the vicinity of the vehicle position mark 40.

  If there is no direction designation operation, the determination in step S5 is NO, and the determination in step S5 is repeated. If there is a direction designation operation, the determination in step S5 is YES, and the process proceeds to step S6.

  In step S6, the direction designated by the direction designation operation is stored. In the first embodiment, the direction uses the position of the host vehicle, that is, the position of the first vehicle C1 as a reference position. The direction in which the finger moves from the vicinity of the reference position is set as the direction specified by the direction specifying operation. Therefore, when the direction specifying operation shown in FIG. 6 is performed, it is stored that the direction specified by the direction specifying operation is behind the host vehicle.

  In subsequent step S7, the vehicle position is acquired. This own vehicle position is acquired from the position detection unit 14.

  The subsequent step S8 corresponds to a notification range determination unit. In step S8, the notification range is determined from the direction stored in step S6 and the vehicle position acquired in step S7. In the first embodiment, the size of the notification range is determined in advance. For example, the size of the notification range is a fixed distance. Further, the size of the notification range may be a polygon or circle having a certain size. When the size of the notification range is a fixed distance, in step S8, the fixed distance is determined as the notification range in the direction stored in step S6 with the vehicle position acquired in step S7 as a reference. In addition, when the size of the notification range is a polygon or a circle, the vehicle position is set to a predetermined position on the circumference of the polygon or circle, and the center of gravity of the polygon or circle is determined from the vehicle position. The notification range is determined so that the passing direction is the direction stored in step S6.

  In step S9, the utterance data stored in step S3, the notification range data indicating the notification range determined in step S8, and the event occurrence position data indicating the event occurrence position are transmitted from the wide area communication unit 13 to the server device 20. The event occurrence position is approximately the own vehicle position acquired in step S7.

  The utterance data and the event occurrence position data correspond to the event occurrence information in the claims, and the notification range data corresponds to the notification range information in the claims. Moreover, the process which attaches alerting | reporting range data and transmits speech data and event occurrence position data is equivalent to the alerting | reporting range limitation process of a claim.

  Next, the process of the server apparatus 20 in 1st Embodiment is demonstrated using FIG. The server device 20 periodically executes the process shown in FIG.

  In step S11, the probe position is acquired. The probe position is a current position at which the vehicle C including the in-vehicle device 10 sequentially transmits to the server device 20. As described above, the in-vehicle device 10 sequentially transmits the current position detected by the position detection unit 14 to the server device 20 using the wide area communication unit 13. Therefore, in step S11, a process of receiving the current position transmitted from the in-vehicle device 10 is performed.

  In step S12, it is determined whether utterance data, notification range data, and event occurrence position data have been received. If this determination is NO, the process of FIG. 7 is terminated. If judgment of step S12 is YES, it will progress to step S13.

  In step S13, the utterance data and event occurrence position data determined to have been received in step S12 are transmitted to the vehicle-mounted device 10 mounted on the vehicle whose probe position acquired in step S11 is within the notification range. In addition to the probe position being within the notification range, the utterance data or the like may be transmitted only for vehicles that are heading toward the event occurrence position. In addition, it is determined whether it is moving away from the event occurrence position, not whether it is moving toward the event occurrence position, and even if the probe position is within the notification range, the vehicle is moving away from the event occurrence position. Data or the like may not be transmitted.

  Next, among the processes executed by the ECU 19 of the in-vehicle device 10, a process for receiving and notifying utterance data will be described using FIG. The ECU 19 also periodically executes the process shown in FIG. The description of FIG. 8 will be described by taking as an example the case where the in-vehicle device 10B mounted on the second vehicle C2 executes.

  In step S21, it is determined whether utterance data and event occurrence position data have been received. As described with reference to FIG. 7, the server device 20 transmits the utterance data to the in-vehicle device 10 mounted on the vehicle positioned within the notification range. If the current position of the in-vehicle device 10B is within the notification range, the server device 20 transmits the utterance data to the in-vehicle device 10B. If the in-vehicle device 10B receives this utterance data, the determination in step S21 is YES. If determination of step S21 is NO, the process shown in FIG. 8 will be complete | finished.

  In subsequent step S22, the speech data is analyzed. In this analysis, first, speech recognition processing is performed on speech data using a known speech recognition algorithm. Further, based on the words recognized by the speech recognition process, it is determined which type of utterance data is a plurality of types of event specifying information. For example, if there is a word “punk”, the type is determined to be accident information.

  In step S23, with reference to the notification required type memorize | stored in the memory | storage part 11, it is judged whether the classification determined by step S22 is a notification required type. If this determination is NO, the process of FIG. 8 is terminated. On the other hand, if determination of step S23 is YES, it will progress to step S24.

  In step S24, the speech data is output from the speaker 18. Further, in step S25, a map indicating the event occurrence position is displayed on the display unit 15. Steps S22 to S25 correspond to a notification processing unit.

  As described above, according to the first embodiment described above, the utterance data which is the event occurrence information and the event occurrence position data are transmitted (S9). However, the notification range for notifying the utterance data and event occurrence position data is determined based on the direction specified by the occupant in the direction specifying operation (S8), and the notification range data indicating the notification range is set as the utterance data, the event It is transmitted along with the location data.

  In the examples of FIGS. 5 and 6, the occupant of the first vehicle C1 who has seen the punctured vehicle determines that the presence of the punctured vehicle needs to be reported only behind the first vehicle C1. The rear direction is input as the notification direction from the first vehicle C1. Therefore, the notification range is limited to the rear of the first vehicle C1.

  Accordingly, in the examples of FIGS. 5 and 6, the information that the punctured vehicle is present is not necessary, and it is not notified that the punctured vehicle is present ahead of the first vehicle C <b> 1. On the other hand, it is notified that a punctured vehicle is present in a vehicle located behind the first vehicle C1. Therefore, since there is a possibility of traveling in a future location where the punctured vehicle exists, it is possible to prevent the information from being reported to the vehicle that needs information that the punctured vehicle exists.

Second Embodiment
Next, a second embodiment will be described. In the following description of the second embodiment, elements having the same reference numerals as those used so far are the same as elements having the same reference numerals in the previous embodiments unless otherwise specified. In addition, when only a part of the configuration is described, the embodiment described above can be applied to other parts of the configuration.

  FIG. 9 is a part of a flowchart showing a process executed by the ECU 19 in place of FIG. 4 in the second embodiment, and the omitted part executes the same process as in FIG.

  In step S4A, a range designation screen is displayed on display unit 15. FIG. 10 is an example of a range designation screen. The range designation screen shown in FIG. 10 is a road map screen around the current position. The scale of the road map can be changed by pressing the detail button 41 and the wide area button 42 shown in FIG. The road map can also be scrolled by a scroll operation.

  In a succeeding step S5A, it is determined whether or not a range designation operation for designating a notification range has been performed. The range specifying operation in the second embodiment is an operation of tracing the road map displayed on the display unit 15 with a finger. The point of tracing with the finger is the same as in the first embodiment, but in the second embodiment, not only the direction but also the range is determined by this operation. In FIG. 10, a thick line 43 exemplifies a range that the occupant traces with a finger. A thick line 43 is a road on which the first vehicle C1 has traveled.

  In FIG. 10, reference numeral 46 is a graphic (hereinafter referred to as an event generation graphic) indicating a position where a sudden event occurs, such as the presence of a punctured vehicle. This event occurrence figure 46 is for explanation here, and is not actually displayed on the display unit 15. In the example shown in FIG. 10, if the ECU 19 automatically determines the notification range based on the condition that it is behind the host vehicle, the notification range may be set to a range indicated by a two-dot chain line. There is sex. Therefore, the roads 44 and 45 may also be in the notification range. However, the vehicle traveling on these roads 44 and 45 does not pass through the position of the event occurrence graphic 46. Therefore, the information is transmitted even to a vehicle that does not need information that a sudden event has occurred at the position of the event occurrence graphic 46.

  On the other hand, if the occupant designates the notification range by an operation of tracing the road on the road map with a finger, the range indicated by the thick line 43 is set as the notification range without setting the road 44 and the road 45 as the notification range. Can do.

  If the determination in step S5A is no, step S5A is repeated. If the determination in step 5A is yes, the process proceeds to step S6A. The process in step S6A is the same as step S8 in FIG. Therefore, step S6A corresponds to a notification range determination unit.

<Third Embodiment>
In the third embodiment, the control unit 22 of the server device 20 executes the process shown in FIG. 11 instead of the process shown in FIG.

  Steps S31 and S32 are the same as steps S11 and S12 of FIG. 7, respectively. In step S33, the content of the utterance data is determined. In order to determine the content of the speech data, first, speech recognition processing is performed on the speech data using a known speech recognition algorithm. Further, the content of the utterance data is determined based on the words recognized by the voice recognition process.

  In step S34, it is determined whether or not a notification period can be set for the contents of the utterance data determined in step S33. The notification period is until the sudden event indicated by the utterance data disappears. Therefore, in step S34, it is determined whether or not a period until the sudden event indicated by the utterance data can be determined can be determined.

  For example, when the content of the utterance data indicates construction, the construction period for the construction performed at the event occurrence position is searched from the construction period database. The construction period database may be provided in the server device 20, or may be provided in a device different from the server device 20, and the server device 20 may communicate with the device and use the construction period database. Good. If the content of the utterance data indicates an accident, it is determined whether the scheduled processing end time of the accident can be obtained from a computer that manages the road accident. Note that this computer may be used as the server device 20.

  If judgment of step S34 is NO, it will progress to step S35. The process of step S35 is the same as step S13 of FIG. If judgment of step S34 is YES, it will progress to step S36. In step S36, a notification period is set. This step S36 corresponds to a notification period setting unit. The notification period is a period until the sudden event indicated by the utterance data disappears.

In the subsequent step S37, the same processing as in step S35 is executed. In step S38, the probe position is acquired again. In step S39, it is determined whether or not the notification period determined in step S36 has ended. If this determination is NO, the process returns to step S37, and if YES, the process of FIG. 11 is terminated. In addition,
According to the third embodiment, when the notification period can be set from the content of the utterance data (S34: YES), the notification period is set (S36), and the notification range is continuously maintained until the notification period ends. The utterance data and event occurrence position data are transmitted to (S37 to S39). Therefore, even when the server device 20 is not located in the notification range when transmitting the utterance data for the first time, the utterance data, even if the vehicle enters the notification range before the sudden event disappears, Event location data can be transmitted.

<Fourth embodiment>
FIG. 12 is a part of a flowchart showing a process executed by the ECU 19 of the in-vehicle device 10 in place of the process shown in FIG. 4 in the fourth embodiment, and the omitted parts are the same as those in FIG. Run.

  In step S8A, it is determined whether the notification period has been set by the passenger. The occupant uses the touch panel 16 to set the notification period. Further, the notification period may be set by voice input. In the present embodiment, when the notification period is not set within a certain time after the notification range is determined, the notification period is not set (S8A: NO). If the determination in step S8A is NO, step S9 described in FIG. 4 is executed.

  When the notification period is set, the determination in step S8A is YES. In this case, the process proceeds to step S9A. In step S9A, in addition to the utterance data, the notification range data, and the event occurrence position data, notification period data indicating the notification period is also transmitted to the server device 20.

  FIG. 13 shows processing executed by the control unit 22 of the server device 20 in the fourth embodiment. FIG. 13 is different from FIG. 11 only in that step S34A is executed instead of steps S33 and S34 in FIG.

  In step S34A, it is determined whether the notification period data is received together with the speech data determined to have been received in step S32. When the ECU 19 of the in-vehicle device 10 executes Step S9A in FIG. 12, the determination in S34A is YES. On the other hand, when the ECU 19 of the in-vehicle device 10 executes Step S9 of FIG. 12, the determination in S34A is NO. If the determination in step S34A is YES, the process proceeds to step S36, and if NO, the process proceeds to step S35.

  In the fourth embodiment, a vehicle occupant sets a notification period. In many cases, such as small-scale construction or small-scale accidents, the period until completion is not managed by the center. However, even for small-scale construction, the scheduled construction period is often written at the construction position. Also, if an accident passes through the site, it can often be predicted that it will soon end. Therefore, if the vehicle occupant can set the notification period as in the fourth embodiment, the notification period is set even in the event that the period until the end at the center or the like is not managed. , Utterance data, and event occurrence position data can be transmitted.

<Fifth Embodiment>
In the fifth embodiment, the ECU 19 of the in-vehicle device 10 executes the process shown in FIG. 14 instead of the process shown in FIG. The description of FIG. 14 will be described by taking as an example the case where the in-vehicle device 10B mounted on the second vehicle C2 executes, as in the description of FIG.

  Steps S41 to S43 are the same as steps S21 to S23 of FIG. If the determination in step S43 is yes, the process proceeds to step S44. In step S44 corresponding to the travel schedule determination unit, a planned travel route of the second vehicle C2, which is a vehicle that is executing the processing of FIG. 14, is determined. The planned travel route is a route closer to the destination than the current position in the route being guided if route guidance is being performed. When route guidance is not in progress, the vehicle is going straight on the road. In other words, the traveling route ahead of the current position is set as the planned traveling route on the traveling road.

  In step S45, it is determined whether or not there is an event occurrence position on the planned travel route determined in step S44. If the second vehicle C2 is traveling on the same road as the event occurrence position and goes straight, the second vehicle C2 passes through the event occurrence position, but if the planned travel route is a route that turns right and left before the event occurrence position, this step The determination in S45 is NO. In addition, when the notification range includes not only the road where the event occurrence position is located but also another road around the road, the second vehicle may not be traveling on the road where the event occurrence position is located. . Also in this case, the determination in step S45 may be NO.

  If the determination in step S45 is NO, steps S46 and S47 are executed. Steps S46 and S47 are the same as steps S24 and S25 in FIG. 8, respectively. In step S46, the utterance data is output from the speaker 18, and in step S47, a map indicating the event occurrence position is displayed on the display unit 15.

  If the determination in step S45 is yes, the process proceeds to step S48. In step S48, it is determined whether there is a branch point between the current position and the event occurrence position. Steps S45 and S48 correspond to a branch presence / absence determining unit. If the determination in step S48 is NO, steps S46 and S47 are executed.

  If the determination in step S48 is YES, the event occurrence position can be bypassed via the branch point. Therefore, in step S49 corresponding to the detour determination unit, a detour that can return to the planned travel route via the branch point and at a position ahead of the event occurrence position is searched.

  Step S50 is the same as step S46, and the utterance data determined to have been received in step S41 is output from the speaker 18. In step S51, in addition to the event occurrence position, a map showing the detour searched in step S49 is displayed on the display unit 15.

  In the fifth embodiment, the information to be notified varies depending on whether or not the event occurrence position is scheduled to travel and whether or not detouring is possible. That is, if the event occurrence position is scheduled to travel (S45: YES) and the event occurrence position can be bypassed (S48: YES), in addition to notifying the utterance data and the event occurrence position, the detour is also notified. (S50, S51). On the other hand, if the event occurrence position is not scheduled to travel (S45: NO), or the event occurrence position is scheduled to travel but cannot be bypassed (S48: NO), only the utterance data and the event occurrence position are notified. (S46, S47). For example, in FIG. 5, the in-vehicle device 10 mounted on the vehicle Ca reports only the utterance data and the event occurrence position, but the in-vehicle device 10 mounted on the vehicle Cb has a detour in addition to the utterance data and the event occurrence position. Will be notified.

  In this way, by notifying the information to be notified depending on whether or not the event occurrence position is scheduled to travel and whether or not detouring is possible, it is possible to suppress notification of the detour in vehicles that do not require detour information. On the other hand, the information on the detour is notified by the vehicle that needs the detour information.

<Sixth Embodiment>
In 6th Embodiment, ECU19 of the vehicle equipment 10 performs the process shown in FIG. 15 instead of the process shown in FIG. The description of FIG. 15 will also be described by taking as an example the case where the in-vehicle device 10B mounted on the second vehicle C2 executes.

  Steps S61 and S62 are the same as steps S21 and S22 of FIG. 8, respectively. In step S63 corresponding to the necessity determination unit, it is determined whether or not a driving operation is required from the contents of the utterance data analyzed in step S62 and the event occurrence position.

  For example, in the case of utterance data indicating that lane regulation is performed due to construction or an accident, and referring to the travel lane of the second vehicle C2, lane change is necessary. Judgment is YES. In the case where the second vehicle C2 is provided with a lane recognition device that recognizes the travel lane by recognizing the surroundings of the vehicle, the travel lane acquires the travel lane recognized by the lane recognition device. In addition, after the driving lane can be acquired when passing under the light beacon and the steering operation is not performed to change the lane, the vehicle is traveling in the driving lane notified from the light beacon. Shall.

  Another example of determining that a driving operation is necessary is when there is a traffic jam ahead. In this case, a deceleration operation is required.

  If judgment of step S63 is NO, it will progress to step S64. In step S64, the speech data is output from the speaker 18. In step S65, a map showing the event occurrence position is displayed on the display unit 15. Therefore, when it is not determined that the driving operation is necessary, the utterance data and the event occurrence position are notified immediately after the utterance data is received.

  On the other hand, if the determination in step S63 is YES, in step S66, the notification position is determined from the driving characteristics of the driver learned in advance and the driving operation determined to be necessary in step S63.

  The ECU 19 also learns driving characteristics. As a method for learning driving characteristics, for example, in the case of a lane change, during the route guidance, in the driving operation history in which the lane change is made before the intersection that turns right or left, the average value of the distance from the lane change point to the intersection, The learning value for changing lanes. If the vehicle is decelerating, the average value of deceleration start points when stopping at an intersection is used as a learning value in the deceleration operation. In these, the intersection is used because it is clear as a point where the driving operation needs to be completed. However, you may learn the driving | running characteristic of lane change and deceleration operation by methods other than this. The lane change and the deceleration operation are examples of driving characteristics to be learned, and the driving characteristics may be learned for other driving operations. The learning of driving characteristics may be performed for each driver by identifying the driver. For identification of the driver, various known methods such as ID input are used.

  In step S67, it is determined whether or not the notification position has been reached. If this determination is NO, the determination in step S67 is repeated. If the determination in step S67 is yes, the process proceeds to step S68.

  In step S68, in addition to the speech data, the necessary driving operation is also output from the speaker 18. In a succeeding step S69, a map indicating the event occurrence position is displayed on the display unit 15.

  In the sixth embodiment, when driving characteristics are learned and it is determined that it is necessary to perform a driving operation on an unexpected event indicated by the utterance data (S63: YES), the utterance data is immediately obtained. The notification position is determined from the driving characteristics (S64). When the notification position is reached, the driving operation determined to be necessary is notified in addition to the speech data (S68). Therefore, since it is informed to the driver that the driving operation is necessary at the driving operation timing at which the driver often performs the driving operation, the driver can easily perform the driving operation.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the above-mentioned embodiment, The following modification is also contained in the technical scope of this invention, Furthermore, the summary other than the following is also included. Various modifications can be made without departing from the scope.

<Modifications 1 and 2>
For example, in the above-described embodiment, the server device 20 transmits the utterance data and the event occurrence position data to the in-vehicle device 10 mounted on the vehicle existing within the notification range. I can't. The server device 20 broadcasts the utterance data, the event occurrence position data, and the notification range data by broadcasting to a range wider than the notification range, and the vehicle-mounted device 10 that has received these data performs notification from the current position. It may be determined whether or not (Modification 1).

  In addition, when the in-vehicle device 10 that has received the speech data, the event occurrence position data, and the notification range data determines whether or not to perform notification from the current position, it is not the server device 20 but the step S9 in FIG. Speech data, event occurrence position data, and notification range data may be transmitted by broadcast from the in-vehicle device 10 using the distance communication unit 12 (Modification 2).

<Modification 3>
Further, the utterance data and the event occurrence position data may be transmitted by unicast using the short-range communication unit 12. FIG. 16 shows the processing. FIG. 16 is a part of a flowchart showing processing executed by the ECU 19 in place of FIG. 4 in the third modification, and the omitted portion executes the same processing as FIG.

  In step S <b> 8 </ b> B, the surrounding vehicle position is acquired by inter-vehicle communication using the short-range communication unit 12. The position of the surrounding vehicle acquired here corresponds to the position of the transmission destination candidate. In step S8C, the transmission destination is determined from the transmission range determined in step S8 and the surrounding vehicle position acquired in step S8B. In step S9B, utterance data and event occurrence position data are transmitted to the transmission destination determined in step S8C by unicast using the short-range communication unit 12. The processing in the in-vehicle device 10 performed to receive these data is the same as in FIG. In the second and third modifications, the short-range communication unit 12 corresponds to a transmission unit and a reception unit in claims.

<Modification 4>
Moreover, the short range communication part 12 provided with the variable directivity antenna is provided, utterance data and event occurrence position data may be transmitted from the short range communication part 12 by limiting the transmission direction. In this case, the notification range need not be determined. This is because the communication range of the short-range communication unit 12 is originally about several hundred meters.

<Modification 5>
In the above-described embodiment, an example in which event specifying information is input from the microphone 17 has been shown. However, a list of event specifying information is displayed on the display unit 15, and the event specifying information is selected from the list using the touch panel 16. You may make it do.

<Modification 6>
In the first embodiment, the size of the notification range is determined in advance, but the size of the notification range is large enough to reach the event occurrence position within the time until the sudden event specified by the event specifying information disappears. You may set it. The time until the sudden event disappears is determined in the same manner as in the third embodiment. The time until this sudden event disappears is multiplied by the average movement speed to determine the size of the neglected range.

<Modification 7>
In the first embodiment, the notification required type is stored in the storage unit 11 and the utterance data is notified when the type of the received utterance data is the notification required type. However, the present invention is not limited to this. The notification-unnecessary type is stored in the storage unit 11, and as shown in FIG. 17, it is determined in step S23A whether the type of the received utterance data is the notification-unnecessary type. When it is determined that the type of utterance data is a notification-unnecessary type (S23A: NO), notification is not performed, but when it is determined that the type of utterance data is not a notification-unnecessary type, the same as in the first embodiment. Steps S24 and S25 may be executed. In the modified example 7, steps S22 to S25 correspond to the notification processing unit.

<Modification 8>
The operation for designating the notification range using the touch panel 16 is not limited to the tracing operation. The notification range may be designated in predetermined block units such as between intersections by a tap operation. In the example of FIG. 18, reference numerals 51 to 54 indicate the notification range set by one tap operation.

<Modification 9>
In the above-described embodiment, the vehicle-mounted device 10 is exemplified as the vehicle information transmission device and the vehicle information notification device. However, the vehicle information transmission device and the vehicle information notification device are portable and brought into the vehicle. It may be used.

<Modification 10>
In the above-described embodiment, the utterance data input as the event specifying information is used as part of the event occurrence information, and the utterance data is output as it is from the speaker 18 in step S24. However, the present invention is not limited to this. The speech data may be analyzed and characters corresponding to the speech data may be displayed on the display unit 15.

<Modification 11>
In the above-described embodiment, even when the in-vehicle device 10 receives utterance data or the like, the in-vehicle device 10 may not notify the utterance data when it is not directed to the event occurrence position. In addition, it is determined whether it is away from the event occurrence position instead of whether it is toward the event occurrence position, and when it is away from the event occurrence position, the utterance data or the like may not be notified.
