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

FIG. 1 is a diagram showing an information notification system 1 according to an embodiment of the present invention.
This information notification system 1 is used when an event that may affect the traveling of the vehicle 2 occurs in front of the traveling direction K of the route R (hereinafter referred to as “traveling route”) along which the vehicle 2 travels. Is a system for notifying the driver of the vehicle 2 as a user.
As shown in FIG. 1, the information notification system 1 includes an in-vehicle information notification device 4 that is an in-vehicle device mounted in each of a plurality of vehicles 2, and each of the in-vehicle information notification devices 4 performs predetermined wireless communication. The event information 5 indicating the occurrence of the event is transmitted and received by the inter-vehicle communication W used. In addition, when the event information 5 is acquired, the in-vehicle information notification device 4 notifies the driver of the vehicle 2 of the occurrence of the event of the event information 5. Furthermore, the in-vehicle information notification device 4 also has a function of a so-called navigation device.

FIG. 2 is a diagram illustrating a functional configuration of the in-vehicle information notification device 4.
The in-vehicle information notification device 4 includes a control unit 10, an event information transmission unit 6, an event information reception unit 8, an information notification unit 9, and a storage unit 12.

The control unit 10 controls each unit of the in-vehicle information notification device 4 and is configured by a macro computer including a CPU, a ROM, a RAM, and the like, and by executing a predetermined control program by the CPU, in-vehicle information notification Each part of the apparatus 4 is controlled.
The control part 10 of this embodiment implement | achieves the function of the navigation function part 14, the vehicle control part 16, and the notification control part 18 by running the said predetermined | prescribed control program.

The navigation function unit 14 includes general functions that the navigation device has such as display of a map, display of a vehicle position on the map, setting of a guidance route, and route guidance.
The vehicle control unit 16 controls the traveling of the vehicle 2. In the present embodiment, the vehicle control unit 16 has a control function of operating the brake while the vehicle 2 is traveling to stop the vehicle 2.
The notification control unit 18 controls notification to the driver based on the event information 5 described above. This control will be described later.

  The event information transmission unit 6 is a unit that transmits an event to the surroundings by inter-vehicle communication W when an event occurs in the own vehicle 2, and includes a state detection unit 20, a position detection unit 22, and a user input unit. 24 and an event information transmission unit 26.

The state detection unit 20 detects the occurrence of an event in its own vehicle 2.
In the present embodiment, the state detection unit 20 detects the occurrence of sudden braking in the vehicle 2 and the occurrence of a failure in the vehicle 2 as the occurrence of this event. The sudden braking is a driving operation that is performed in an emergency for the purpose of avoiding an accident or the like while the vehicle 2 is driving the vehicle 2. For example, sudden braking corresponds to this driving operation. Examples of the failure of the vehicle 2 include a tire puncture and a trouble of a power mechanism such as an engine.

  The state detection unit 20 includes various sensors for detecting the traveling state, the vehicle state, and the driving state of the vehicle 2 in order to detect sudden braking and failure of the vehicle 2 itself. This type of sensor includes a vehicle speed sensor, an acceleration sensor, a steering angle sensor that detects the steering angle of a steering wheel, a sensor that detects an operation of an accelerator and a brake pedal, a sensor that detects tire air pressure, a power mechanism such as an engine, etc. And a sensor for detecting the state of the above.

  The position detection unit 22 detects an event occurrence point A in the own vehicle 2. In the present embodiment, the position detector 22 includes a GPS receiver 28 that receives GPS signals from each of a plurality of GPS satellites and identifies the current position. Further, the position detection unit 22 has a function of specifying the current time based on the GPS signal, and a general navigation device also includes various sensors such as a gyro sensor for autonomous driving. In addition, you may provide the time measuring device which time-measures the present time separately.

  The user input unit 24 is an operation device that allows the driver to input the cause of the event.

  The event information transmission unit 26 generates the event information 5 and transmits the event information 5 by the inter-vehicle communication W.

FIG. 3 is a diagram showing a configuration of the event information 5.
As shown in the figure, the event information 5 includes event title information 50, occurrence point information 52, time information 54, occurrence cause information 56, and elimination information 58.
The event title information 50 is information serving as a so-called headline that indicates an event that has occurred in its own vehicle 2 with a small number of characters. For example, when a sudden braking operation is detected, “rapid braking” is stored in the event title information 50, and when a tire puncture or engine trouble is detected, “failure” is stored in the event title information 50. .
The occurrence point information 52 stores the current position detected by the position detection unit 22 when the occurrence of the event is detected by the state detection unit 20.
The time information 54 stores a transmission time, a generation time, and a cancellation time. The transmission time is the time when the event information 5 is transmitted (the time when the event information 5 is generated), and the occurrence time is the time when the event occurs. The cancellation time is the time when the event is resolved. The resolution of the event will be described later.
The occurrence cause information 56 stores detection information of various sensors that cause the state detection unit 20 to detect the occurrence of the event as the cause of the occurrence of the event. For example, when the event title information 50 is “sudden braking”, detection information of driving operation such as “sudden braking” or “sudden steering operation” is stored as the cause. For example, when the event title information 50 is “failure”, vehicle state detection information such as “tire tire puncture” or “engine trouble” is stored.
The resolution information 58 stores information indicating that the event is resolved when the event is resolved. The cancellation information 58 notifies the other vehicle 2 that the event that has occurred in its own vehicle 2 has been resolved. In the present embodiment, the state detection unit 20 detects the resumption of traveling of the vehicle 2 after the occurrence of the event as the cancellation of the event.

The event information transmission part 26 of this embodiment transmits the event information 5 at the following three timings.
The first timing is when the occurrence of an event is detected by the state detection unit 20, and the second timing is when the cancellation of the event is detected by the state detection unit 20. The third timing is when the cause information is input from the user input unit 24.
When the event information transmission unit 26 transmits the event information 5 at the first and second timings, the event information transmission unit 26 does not wait for an input from the user input unit 24 in order to promptly notify the surroundings of the occurrence and resolution of the event. Event information 5 is generated and the event information 5 is transmitted.
On the other hand, when the event information transmission unit 26 transmits the event information 5 at the third timing, the event information transmission unit 26 stores the information input by the user in the occurrence cause information 56 even if the occurrence of the event is not detected by the state detection unit 20. Event information 5 is generated and the event information 5 is transmitted. At this time, the event information transmission unit 26 stores “other” or information designated by the user in the event title information 50. Thereby, for example, when the driver stops the vehicle 2 without sudden braking due to the fall of the load of the own vehicle 2 or the occurrence of falling rocks, and the occurrence of the event is not detected by the state detection unit 20 However, the driver can notify the other vehicle 2 of an event occurring in the route R in front of the own vehicle 2 by inputting the reason from the user input unit 24.

  Returning to FIG. 2, the event information receiving unit 8 acquires the event information 5 transmitted from the other in-vehicle information notification device 4 by receiving the inter-vehicle communication W.

The information notification unit 9 notifies the driver of the occurrence of the event based on the event information 5, and further outputs a display and sound for route guidance of the vehicle 2 in the present embodiment.
Specifically, the information notification unit 9 includes a display device 30 and an audio output unit 32.
The display device 30 is a device having a display area 40 (see FIG. 11) having a predetermined size for displaying various information, and is, for example, a liquid crystal display panel or an organic EL display panel. In addition, the display device 30 according to the present embodiment includes a touch operation unit 34 that receives a user's touch operation.
The audio output unit 32 is, for example, a speaker device that outputs various sounds.

At the time of route guidance by the navigation function unit 14, the display area 40 of the display device 30 displays the travel route and the vehicle position along with the surrounding map, and the voice output unit 32 provides guidance voice for guidance. Is output.
When the event information 5 is received, the occurrence of the event of the event information 5 is notified by display or sound under the control of the notification control unit 18.

The storage unit 12 stores various kinds of information, and the storage unit 12 stores map data 36 and notification control data 38.
The map data 36 is map data used for route guidance by the navigation function unit 14.
The notification control data 38 includes various data used for notification control by the notification control unit 18. This data includes voice data for notifying the occurrence of an event by voice, and data for determining a time margin until the vehicle 2 reaches the event occurrence point A (a short distance d1, a short distance described later). d2 and medium distance d3).

Next, the operation of the information notification system 1 will be described.
First, an operation when an event occurs in the vehicle 2 will be described.
FIG. 4 is a flowchart of the transmission process of the event information 5 of the in-vehicle information notification device 4.
When the driver performs a driving operation such as sudden braking while the vehicle 2 is traveling, the sudden braking by the driving operation is detected by the state detection unit 20 as an occurrence of an event (step S1). In step S1, even if the occurrence of the event is not detected by the state detection unit 20, when the driver inputs the cause of the event from the user input unit 24, the input of the cause is regarded as the occurrence of the event. It is detected by the information transmission unit 6.
And the event information transmission part 26 produces | generates the event information 5 of the event detected by step S1, and transmits the event information 5 to the circumference | surroundings by the vehicle-to-vehicle communication W (step S2).

Thereafter, in order to detect whether or not the event has been resolved, the state detection unit 20 detects whether or not the own vehicle 2 has resumed traveling at regular intervals (step S3).
If the vehicle 2 has not resumed running (step S3: NO), the processing procedure returns to step S2 to continuously notify the occurrence of the event, and the event information transmission unit 26 transmits the event information 5.
On the other hand, when the vehicle 2 resumes running (step S3: YES), in order to notify the cancellation of the event, the event information transmission unit 26 stores the event information 5 in which information indicating the cancellation is stored in the cancellation information 58. The event information 5 is generated and transmitted to the surroundings (step S4).

Next, an operation when the event information 5 is transmitted from the in-vehicle information notification device 4 of another vehicle 2 will be described.
5 and 6 are diagrams for explaining the event information receiving operation of the in-vehicle information notifying device 4, and FIG. 5 is a diagram showing the positional relationship between the event occurrence point A and the own vehicle 2. . FIG. 6 is an explanatory diagram when a plurality of pieces of event information are transmitted locally and at the same time.

When the event information receiving operation is outlined, in the information notification system 1, when the in-vehicle information notification device 4 receives the event information 5, based on the event information 5, notification of the occurrence of the event and cancellation of the notification are performed.
In the notification of the occurrence of the event, the driver is notified of the occurrence of the event, limited to the occurrence of the event that may affect the traveling of the own vehicle 2. This makes it easy for the driver to grasp only important notifications when the vehicle 2 is traveling without being bothered by a large number of notifications.
In addition to this, in the notification of the occurrence of an event, the occurrence of the event is determined according to a predetermined time until the vehicle 2 reaches the event occurrence point A, that is, the driver's time margin corresponding to the occurrence of the event. The notification mode is changed. Thereby, since the occurrence of the event is notified in a notification mode commensurate with the time margin, the driver can understand the urgency of the occurrence of the event and appropriately deal with the urgency.

This section outlines the limited operation for notification of event occurrence.
In general, not all events that occur around a certain vehicle 2 necessarily affect the traveling of the vehicle 2. Examples of the event that does not affect the traveling of the vehicle 2 include “an event that has not occurred on the traveling path of the vehicle 2”. That is, since the possibility that the vehicle 2 travels at the occurrence point A of this event is low, this event can be regarded as an event that does not affect the travel of the vehicle 2.

  Here, the “advance route” refers to a route R on which the vehicle 2 may travel after the present time. Specifically, the route R on which the vehicle 2 is currently traveling and the route on which the vehicle 2 is scheduled to travel. Includes both paths of R.

As the route R scheduled to travel, the following three may be mentioned.
The first is a route R included in the guidance route guided by the navigation function unit 14.
Second, when the guide route is not set by the navigation function unit 14, as shown in FIG. 5, the other route that joins at the junction P1 ahead of the traveling direction of the route R1 on which the vehicle 2 is traveling is shown. Route R.
Third, when the guide route is not set by the navigation function unit 14, as shown in FIG. 5, other routes intersecting at the intersection P2 ahead of the traveling direction of the route R2 on which the vehicle 2 is traveling. Route R.

  Further, it may be desirable to limit notification even for an event that affects the traveling of the vehicle 2. Specifically, this is a case where a plurality of events occur locally and at the same time (for a short time).

More specifically, as shown in FIG. 6, when a sudden braking occurs in the leading vehicle 2 when a plurality of vehicles 2 are traveling on the route R in the same traveling direction K, this sudden braking is caused. Thus, sudden braking also occurs in the following vehicle 2. At this time, since the event information 5 is transmitted from each of the head and the following vehicles 2, a plurality of event information 5 in which the occurrence points A are locally concentrated are transmitted at the same time.
However, in terms of the influence on the traveling of the other vehicle 2, if the event that occurred in the leading vehicle 2 that is the origin of these events is notified to the other vehicle 2, the notification of the other events is not necessary. is there. Rather, if all of these events are notified to the driver of the other vehicle 2, a large number of notifications are output all at once, making it very difficult for the driver to grasp each notification.
For this reason, when multiple events occur locally and at the same time (for a short period of time), other events other than the event that occurred first are excluded from the notification target and the notification is restricted. Is done.

  In the present embodiment, when the occurrence time of each event is within a predetermined time and the generation point A is within the range C of the predetermined distance f as shown in FIG. And at the same time (short period). The center of the range C is the occurrence point A of the event that has occurred first.

Next, an outline of the notification mode commensurate with the time margin will be described.
As shown in FIG. 5, the time required to reach the occurrence point A, that is, the time margin differs depending on the distance d along the route R from the occurrence point A to the vehicle 2. In the present embodiment, the distance d is classified into three, that is, the closest distance d1, the short distance d2, and the medium distance d3, based on the viewpoint of the time margin for the driver to deal with the event.
Even if the route including the event occurrence point A is the route R that the vehicle 2 is scheduled to travel and is not the currently traveling route R, the distance d is a straight line connecting the occurrence point A and the current position of the vehicle 2. Instead of the distance, the distance along the route R to the point of occurrence A is used.

The close distance d1 is a distance at which the driver has no time to respond to the event even if the driver is notified of the occurrence of the event.
The short distance d2 is a distance having a time margin enough to deal with an event if the driver responds promptly.
The intermediate distance d3 is a distance where the driver has a time margin for responding to the event and the time margin is not too large. A state where there is too much time means a state where it is unlikely that the driving of the vehicle 2 will be affected even if the driver does not recognize the occurrence of the event at that time.

  The event occurrence notification mode is controlled according to whether the distance d of the vehicle 2 corresponds to the closest distance d1, the short distance d2, or the intermediate distance d3, thereby meeting the time margin of the driver. Appropriate notifications are made.

  The setting data for the close distance d1, the short distance d2, and the intermediate distance d3 are stored in the notification control data 38 in advance. In the present embodiment, it is assumed that the legal speed of each route R is the same, and therefore the time required for the vehicle 2 to reach the generation point A is estimated by the distance d. When the speed of the vehicle 2 is different, the time required for the vehicle 2 to reach the generation point A also depends on the speed of the vehicle 2, so that the close distance d 1, the short distance d 2, and the intermediate distance d 3 Data that varies at a speed of 2 is used.

These outlined operations are then described in detail.
7-10 is a flowchart which shows the event information reception notification process of the vehicle-mounted information notification apparatus 4. FIG. FIG. 8 is a flowchart showing a process following A shown in FIG. 7, and FIG. 9 is a flowchart showing a process following B shown in FIG. FIG. 10 is a flowchart showing processing subsequent to C shown in FIG.

  As shown in FIG. 7, when the event information 5 is received (step S10), the notification control unit 18 executes the following two determination processes in order to determine the necessity of limiting the notification of the occurrence of the event. To do.

That is, first, the notification control unit 18 determines whether or not a plurality of events have occurred within a predetermined time and within a predetermined distance based on the occurrence time and the occurrence point A included in the event information 5. (Step S11).
If this determination result is affirmative (step S11: YES), since a plurality of events have occurred locally and in a short time, the notification control unit 18 selects the event information 5 with the earliest occurrence time. The other event information 5 is excluded from the notification target (step S12).
If the determination result of step S11 is negative (step S11: NO), there is no event information 5 to be excluded, and therefore all received event information 5 is selected as a notification target.

Next, secondly, the notification control unit 18 determines whether or not the event information 5 to be notified is information related to an event that has occurred on the travel route of the vehicle 2.
Specifically, the notification control unit 18 determines whether or not the own vehicle 2 is traveling on the route R including the event occurrence point A toward the occurrence point A (that is, on the road including the occurrence point A). It is determined whether or not its own vehicle 2 is present (step S13).
Further, when the own vehicle 2 is not present on the route including the occurrence point A (step S13: NO), whether or not the route R including the occurrence point A is the above-described scheduled travel route R of the own vehicle 2 is determined. Is determined (step S14).

  If the determination results in steps S13 and S14 are negative (step S13: NO, and step S14: NO), the event to be notified is not an event that has occurred on the traveling route of the vehicle 2 itself, so notification is made. The control unit 18 makes the notification of the occurrence of the event unnotified (step S15).

Here, in step S14, when the route R including the generation point A corresponds to another route R that intersects at the intersection in front of the traveling direction of the route R on which the vehicle 2 is traveling, the vehicle 2 starts from the intersection. Positioning within a certain distance along the route R is added to the determination condition. That is, when there is a certain amount of time or more until the vehicle 2 enters the intersection on the route R including the generation point A (when the vehicle 2 is more than a certain distance from the intersection), the route R including the generation point A is The traveling route of the vehicle 2 is not considered.
Therefore, there is a high possibility that the vehicle 2 enters the route R including the occurrence point A at the intersection, and the occurrence of the event is not notified until the necessity of notification occurs. This prevents the driver from being notified of the event in a situation where the event can be resolved before the vehicle 2 approaches a certain distance from the intersection.

If the determination result of any of the above steps S13 and S14 is affirmative (step S13: YES or step S14: YES), an event of event information 5 has occurred on the travel route of the vehicle 2 Will be.
In this case, the notification control unit 18 performs the following process in order to notify the driver of the occurrence of the event in a notification mode commensurate with the time margin.
That is, the notification control unit 18 first determines whether or not the distance d (the distance along the road) from the vehicle 2 to the event occurrence point A is equal to or less than the closest distance d1 (step S16). When this determination result is affirmative (step S16: YES), even if the driver is notified of the occurrence of the event, the driver does not have time to respond to the event. Therefore, the notification control unit 18 uses the brake control by the vehicle control unit 16 to stop the vehicle 2 until it reaches the generation point A (step S17). Accordingly, even when there is no time for the driver to perform a driving operation with respect to the occurrence of the event, the driving is appropriately assisted.
In step S17, the fact that the vehicle control is automatically executed and the notification about the event may be performed together with the vehicle control by display or voice.

On the other hand, when the vehicle 2 is away from the event occurrence point A by the closest distance d1 or more (step S16: NO), the notification control unit 18 is connected to the vehicle 2 and the event in steps S20 and S21 as shown in FIG. It is determined whether the distance d to the generation point A is a short distance d2 or less, a short distance d2 or more, a medium distance d3 or less, or a medium distance d3 or more.
When the distance d between the vehicle 2 and the event occurrence point A is equal to or greater than the medium distance d3 (step S21: NO), there is no necessity for notifying the occurrence of the event, and there is no urgency. The occurrence of the event is not notified and is not notified (step S22).

On the other hand, when the distance d between the vehicle 2 and the event occurrence point A is the short distance d2 or less, or the short distance d2 or more and the middle distance d3 or less (step S20: YES or step S21: YES), the notification control unit 18, the occurrence of the event is notified in a manner that is more easily recognized by the driver as the distance d is shorter.
Specifically, when the distance d between the vehicle 2 and the event occurrence point A is equal to or less than the short distance d2, the notification control unit 18 displays a notification screen 60 for notifying the occurrence of the event in the display area 40 of the display device 30. Display in full screen. Further, along with this display, the notification control unit 18 outputs audio data for notifying the occurrence of the event from the audio output unit 32 (step S23).
On the other hand, when the distance d between the vehicle 2 and the event occurrence point A is not less than the short distance d2 and not more than the medium distance d3, the notification control unit 18 partially displays the notification screen 60 on the display area 40 of the display device 30. The voice data is not output (step S24).

FIG. 11 is a diagram illustrating an example of a full screen display of the notification screen 60, and FIG. 12 is a diagram illustrating an example of a partial display of the notification screen 60.
As shown in FIG. 11, in the full screen display of the notification screen 60, the notification screen 60 is displayed on the entire display area 42 of the display device 30. On the notification screen 60, a message 61 that prompts attention and warning due to the occurrence of an event, an icon 62, and distance information 63 from the vehicle 2 to the point of occurrence A are displayed. Furthermore, the road 64 on which the vehicle is traveling is displayed on the notification screen 60 during full screen display. In the display of the road 64, the lane 64A in which an event has occurred (that is, the driver should be careful) is displayed in an identifiable manner (colored black in the illustrated example).

  On the other hand, in the partial display of the notification screen 60, the notification screen 60 is displayed so as to overlap with a part of the normal screen 59 (for example, a map screen during route guidance) that is normally displayed in the display area 40. (So-called superimposition). On the notification screen 60 at the time of partial display, the message 61, the icon 62, and the distance information 63 are displayed, and the display of the road 64 is omitted. In the partial display, when a map is displayed on the notification screen 60, the notification control unit 18 displays the icon 62 at the event occurrence point A, so that the driver can easily grasp the occurrence point A.

  Thus, the distance d between the vehicle 2 and the event occurrence point A becomes shorter, and the time required for the vehicle 2 to reach the occurrence point A becomes shorter, that is, the driver has less time margin for the event. Since the ratio of the notification screen 60 occupying the display area 40 is increased, the driver can quickly notice the notification screen 60 and can respond quickly.

Further, when the distance d between the vehicle 2 and the event occurrence point A is short, a voice message for warning the occurrence of the event is output together with the notification screen 60, so that the driver is surely and promptly notified of the event. The occurrence can be recognized.
As an example of this voice message, for example, “There is a possibility that a dangerous event has occurred in the distance of OOm. Reduce speed and drive carefully.” "!"
In this case, the output volume of the voice message may be increased as the distance d between the vehicle 2 and the event occurrence point A is shorter.
Further, in addition to or instead of display and audio output, there may be a form of notification in which the driver's seat is vibrated and the vibration is increased as the distance d is shorter.

In this embodiment, as shown in FIGS. 11 and 12, when the notification screen 60 is displayed, a release button 66 is displayed as an operator that inputs an instruction to erase the screen display of the notification screen 60.
The driver recognizes the occurrence of the event on the notification screen 60 and then operates the release button 66 to delete the notification screen 60, so that the entire normal screen 59 in the display area 40 is not harmed by the notification screen 60. Visible to.

After notifying the occurrence of the event, the notification control unit 18 executes the following process in order to stop the notification as the event is resolved.
That is, as shown in FIG. 9, the notification control unit 18 determines whether or not the vehicle 2 that has transmitted the event information 5 has resumed running after a predetermined time from the transmission time of the event information 5 (step S30). .
If an event has occurred locally and at the same time in a plurality of vehicles 2, it is determined in step S30 whether any one of the vehicles 2 has resumed traveling. As a result, even if the vehicle 2 that has transmitted the event information 5 of the event that has occurred first cannot subsequently transmit the event information 5 indicating that it has been resolved for any reason, the event of any other vehicle 2 Based on the information 5, the resolution of the event can be acquired, and the notification can be stopped promptly.
In step S30, the determination as to whether or not to resume traveling is made based on whether or not the vehicle 2 that has transmitted the event information 5 has subsequently transmitted the event information 5 including the cancellation information 58 indicating that the event has been resolved.

  When the determination result of step S30 is affirmative (step S30: YES), the event that has occurred on the travel route is resolved, indicating that the vehicle 2 can travel on the travel route. In this case, the notification control unit 18 stops the display of the notification screen 60 in order to stop the notification of the occurrence of the event (step S31).

On the other hand, when the determination result of step S30 is negative (step S30: NO), the notification control unit 18 continues to notify the occurrence of the event. However, at this point in time, as the vehicle 2 subsequently travels, there is a possibility that the occurrence point A of the event notified earlier is off the traveling path of the vehicle 2. Therefore, the notification control unit 18 executes the same processes as those in steps S13 and S14 described above in steps S32 and S33.
And when the judgment result of step S32 and S33 is negative (step S32: NO and step S33: NO), the occurrence point A of the event notified previously deviates from the traveling route of the own vehicle 2. Therefore, the notification control unit 18 stops displaying the notification screen 60 that notifies the occurrence of the event (step S34).

When the determination result of either step S32 or S33 is affirmative (step S32: YES or step S33: YES), the previously notified event continuously occurs on the traveling path of the vehicle 2 Will be.
In this case, the notification control unit 18 informs the driver that the event is continuously generated by the processing of steps S40 to S44 shown in FIG. 10 in a manner corresponding to the time margin at that time. Notice. Each of these steps S40, S41, and S43, S44 is the same as steps S20, S21, S23, and S24 shown in FIG.

  On the other hand, in step S42, since the previously notified event has not been resolved, the display of the notification screen 60 is not stopped even if the vehicle 2 is separated from the event occurrence point A by the intermediate distance d3 or more. Continue to display. In this case, in this embodiment, the amount of information included in the notification screen 60 is reduced. Specifically, as shown in FIG. 13, in the display area 40 of the display device 30, a notification screen 60 showing only the icon 62 is displayed on the normal screen 59.

  In addition, when the previously notified event continues to occur on the traveling route of the vehicle 2 (step S32: YES or step S33: YES), the event occurrence point A continues to be unpassable. It has become. Therefore, when displaying the notification screen 60, the notification control unit 18 displays on the notification screen 60 that the occurrence point A cannot pass according to the elapsed time from the occurrence time of the event, and notifies the driver. Further, detouring of the occurrence point A may be promoted.

  The embodiment described above has the following effects.

The in-vehicle information notification device 4 according to the present embodiment includes an event information receiving unit 8 that receives an event that has occurred in the traveling route of the vehicle 2 and an event information 5 that includes the occurrence point A, and an information notification unit 9 that notifies the occurrence of the event. And a notification control unit 18 that controls the mode of the notification in the information notification unit 9 based on the time required for the vehicle 2 to reach the generation point A.
According to this configuration, the events to be notified are limited to events that have occurred in the traveling path of the vehicle 2 instead of all events that have occurred around the vehicle 2. As a result, the driver recognizes only the occurrence of an event that affects the progress of the vehicle 2 and is not bothered by the occurrence of other events.
In addition, the event notification mode is not uniform, and the notification mode is controlled based on the time required for the vehicle 2 to reach the event occurrence point A. Thereby, it is possible to notify the driver of the occurrence of the event in a manner suitable for the time margin that the driver corresponds until the point of occurrence A is reached.

When the distance d along the route R from the vehicle 2 to the generation point A is equal to or greater than the intermediate distance d3, that is, the required time is equal to or greater than the first threshold corresponding to the intermediate distance d3. If the event is expected to occur, the occurrence of the event is not notified.
Thereby, when there is too much time for the driver to respond before the vehicle 2 reaches the generation point A, the event can be prevented from being notified. Therefore, the driver is not bothered by the occurrence of an event of relatively low urgency in the progress of the vehicle 2 and is not bothered.

The in-vehicle information notification device 4 of the present embodiment includes a vehicle control unit 16 that controls the traveling of the vehicle 2, and the notification control unit 18 has a distance d along the route R from the vehicle 2 to the generation point A that is the closest distance d1. In the following case, that is, when the required time is expected to be equal to or less than the second threshold corresponding to the closest distance d1, the vehicle is stopped by the control of the vehicle control unit 16.
Thereby, when there is no time margin for the driver to reach the event occurrence point A, the driver's driving is appropriately assisted.

In this embodiment, the event information 5 includes an event occurrence time, and the notification control unit 18 receives a plurality of event information 5 in which the occurrence point A is within a predetermined distance and the occurrence time is within a predetermined time. In such a case, the information notification unit 9 notifies the event information 5 having the earliest occurrence time among these event information 5.
As a result, when multiple events occur locally and simultaneously due to the occurrence of one event, only the occurrence of the earliest event that caused it is notified, and the occurrence of other events is notified. Can be limited. Therefore, the driver is not bothered by the notification of the occurrence of the main factor, and the occurrence of the main factor is easily grasped without being bothered by the notification of the occurrence of another event.

In the present embodiment, the event information 5 includes the resolution information 58 indicating the resolution of the event, and the notification control unit 18 receives the notification in the information notification unit 9 and the event information 5 including the resolution information 58 indicating the resolution of the event. Continue until is received.
Since the notification of the occurrence of the event is continued until the event is resolved, the driver can more reliably recognize the occurrence of the event. In addition, the driver can grasp that the event has been resolved when the notification is stopped.
In addition to this, while the notification of the occurrence of the event is continued, the notification mode changes according to the required time. As a result, even if it is difficult for the driver to recognize the notification at the beginning of the notification, the driver can surely recognize the notification as there is no time margin.

In the present embodiment, the event information 5 includes resolution information 58 indicating the resolution of the event, and the notification control unit 18 includes a plurality of events in which the occurrence point A is within a predetermined distance and the occurrence time is within a predetermined time. After the information 5 is received, the notification in the information notification unit 9 is continued until the event information 5 including the resolution information 58 indicating the resolution of any one of the event information 5 is received.
As a result, when a plurality of events occur locally and at the same time due to the occurrence of one event, the notification is continued if none of the events are resolved.
Further, not only the event of the main factor but also any event is resolved, the notification is stopped, so that the vehicle 2 that sent the earliest event has event information 5 thereafter for some reason. Even if the call cannot be transmitted, the resolution of the event can be acquired based on the transmission of another vehicle, and the notification can be stopped immediately.

In the present embodiment, a release button 66 for inputting an instruction to stop the display of the notification screen 60 to the notification screen 60 displayed on the display device 30 of the information notification unit 9 is provided.
Thereby, the driver can stop the display of the notification screen 60 when the occurrence of the event is sufficiently grasped, and the attention is not distracted from the grasped notification, and the driver is not bothered.

In the present embodiment, the information notification unit 9 includes the display device 30, and the notification control unit 18 increases the proportion of the notification screen 60 in the display area 40 of the display device 30 as the required time becomes shorter.
Thus, the notification screen 60 is displayed so that the driver becomes more aware as the required time becomes shorter, that is, as the driver has no time margin to respond and the urgency of the response increases. Therefore, it is possible to prevent oversight of notifications that are highly urgent.
In addition, as described above, since the release button 66 is provided on the notification screen 60, even when the notification screen 60 occupies most of the display area 40 and it is difficult to grasp the display of the normal screen 59. The driver can recognize the entire normal screen 59 without being covered by the notification screen 60 by grasping the notification screen 60 and then stopping the display of the notification screen 60 by operating the release button 66.

In the present embodiment, the traveling route of the vehicle 2 includes a route R on which the vehicle 2 is traveling and a route R on which the vehicle 2 is scheduled to travel.
As a result, not only the event that occurs on the route R while the vehicle 2 is traveling, but also the event that occurs when the vehicle 2 is scheduled to travel, that is, the occurrence of an event that has a high probability of affecting the progress of the vehicle 2 is given to the driver. Can be notified.

In the present embodiment, when the cause of occurrence is input by the user input unit 24, the event information transmitter 26 transmits the event information 5 indicating the occurrence of the event including the cause of occurrence.
Thereby, even if the event is not detected by the event information transmission unit 6, the occurrence of the event can be transmitted to the surroundings together with the cause of occurrence by the user operation.

  The above-described embodiment is merely an example of one aspect of the present invention, and can be arbitrarily modified and applied without departing from the spirit of the present invention.
