FIG. 6 is a flowchart illustrating an example of processing in the in-vehicle device. In the example of FIG. 6, the vehicle power supply control detection unit 21 of the in-vehicle device 20 detects the power ON of the vehicle 11 (S01). When the travel speed condition acquisition unit 22 of the in-vehicle device 20 acquires the detection of the power supply for the vehicle 11 by the process of S01, the travel speed condition acquisition unit 22 inquires the travel speed condition 31 to the management server 12 (S02).

  Next, the traveling speed condition acquisition unit 22 receives the traveling speed condition 31 (S03). The received traveling speed condition 31 is stored in the storage unit 27. The inquiry about the traveling speed condition 31 is preferably acquired before driving, but may be inquired once every predetermined period, for example, and may not be inquired every time the vehicle is turned on. .

  Next, the operation information acquisition unit 23 acquires operation information of the vehicle 11 being driven by the driver (S04). The acquired operation information 32 is stored in the storage unit 27 and transmitted to the management server 12 at a predetermined timing. Next, the traveling state determination unit 24 of the vehicle 11 compares the current operation information 32 with the traveling speed condition 31 (S05), and the current driving of the driver (behavior of the vehicle 11) is notified by a message or an alarm. It is determined whether or not it is a target (S06). Examples of the behavior of the vehicle 11 include, but are not limited to, sudden braking, sudden acceleration, and sudden steering.

The determination as to whether or not to end the process may be, for example, a case where the vehicle power supply control detection unit 21 of the in-vehicle device 20 detects that the vehicle 11 is turned off, but is not limited thereto. In-vehicle device 20 ends the notification process when the process ends (YES in S08).

<Example of processing in management server 12 (travel speed condition setting processing)>
Next, each process in the management server 12 will be specifically described. The process in the management server 12 is roughly divided into a process for setting a travel speed condition and a process for transmitting a travel speed condition corresponding to an inquiry from the vehicle 11, and will be described separately.

  FIG. 7 is a flowchart illustrating an example of a traveling speed condition setting process in the management server. In the example of FIG. 7, the operation information receiving unit 41 of the management server 12 acquires the operation information of each vehicle (S11). Next, the totaling unit 42 of the management server 12 performs totaling under a predetermined condition based on the information acquired in the process of S11 (S12). In the process of S12, for example, the position, time, and the like at the time when the driver has performed a predetermined operation event such as sudden braking are counted.

  Next, the traveling speed condition setting unit 43 of the management server 12 sets the traveling speed condition 53 based on the counting result obtained in the process of S12 (S13), and the set traveling speed condition 53 is stored in the storage unit 46. Store (S14).

In the example of FIG. 8, the traveling speed condition setting unit 43 acquires sudden braking occurrence information from an aggregation result for each predetermined distance range from a certain target intersection as an example of a predetermined area (S21).

  Next, the traveling speed condition setting unit 43 counts the number of sudden brakings for each distance and speed zone (speed range) from the intersection, and sets the distance and speed zone to be notified (S22). In the process of S22, the traveling speed condition setting unit 43 may set a traveling speed condition corresponding to each using at least one of the vehicle type, vehicle weight, driver information, and weather information, for example.

  Next, the traveling speed condition setting unit 43 determines whether or not there is an unprocessed intersection (S23). If there is an unprocessed intersection (YES in S23), the process returns to S21. If there is no unprocessed intersection (NO in S23), the process is terminated.

<Example of processing in management server 12 (travel speed condition transmission processing)>
FIG. 9 is a flowchart illustrating an example of a traveling speed condition transmission process in the management server. In the example of FIG. 9, the transmission unit 44 of the management server 12 determines whether or not there is an inquiry about the traveling speed condition 53 from the vehicle 11 (S31), and when there is an inquiry (YES in S31), the inquiry The vehicle information of the vehicle 11 (vehicle type, vehicle weight, driver information, travel speed condition corresponding to the weather, etc. is acquired (S32). In the process of S32, the transmission unit 44 determines that the vehicle 11 from the vehicle information 54. The travel speed condition 53 for a predetermined area (for example, an intersection or a sharp curve) corresponding to the acquired route may be acquired, and all the travel speed conditions 53 stored in the storage unit 46 may be acquired. You may get it.

  Next, the transmission unit 44 transmits the travel speed condition 53 acquired in the process of S32 to the vehicle 11 that has inquired (S33). In the process of FIG. 9, the travel speed condition is transmitted by an inquiry from the vehicle 11. However, in the present embodiment, the present invention is not limited to this. For example, the travel speed condition is periodically or irregularly set. When the update is performed, the traveling speed condition 53 may be automatically transmitted to each vehicle 11.

<Data example>
Next, an example of data applied in the present embodiment will be described with reference to the drawings. FIG. 10 is a diagram illustrating an example of data applied in the present embodiment. 10A shows an example of operation information, FIG. 10B shows an example of vehicle information 54, and FIG. 10C shows an example of driver information 55.

The vehicle ID is information for identifying the vehicle 11. In the example of FIG. 10A, only the vehicle ID “0001” is stored, but the operation information 51 managed by the management server 12 also stores information from other vehicles.

  The date / time is date / time information in which operation information is recorded. The latitude and longitude are position information corresponding to the date and time obtained from a position sensor such as GPS. The speed is speed information of the vehicle 11 obtained from a speed sensor or the like at the position. The G value (front and rear), the G value (horizontal), and the G value (up and down) are information indicating the magnitude of acceleration in the front and rear direction, the horizontal direction, and the vertical direction of the vehicle 11 obtained from an acceleration sensor or the like. For example, by comparing the value of G value (front and back) with a threshold value, the behavior of the vehicle 11 can be detected such as sudden braking or sudden start. Further, for example, the meandering operation of the vehicle 11 can be detected by comparing the value of the G value (horizontal) with a threshold value. Note that the detection method for sudden braking or the like is not limited to this, and for example, it can be acquired according to a speed displacement amount at a predetermined time or a predetermined distance.

  The items of the vehicle information 54 shown in the example of FIG. 10B include, for example, “vehicle ID”, “vehicle type”, “total vehicle weight (kg)”, “maximum loading capacity (kg)”, “vehicle width (mm) ) "Etc., but is not limited to this. The vehicle ID is information for identifying the vehicle 11. The vehicle type is information indicating the type of vehicle. Examples of the vehicle type include a medium-sized vehicle and a large vehicle, but are not limited thereto, and may be specific vehicle type information such as a bus or a taxi. The total vehicle weight is information indicating the weight of the vehicle 11. The maximum load capacity is information indicating the weight that the vehicle 11 can load. The vehicle width is information indicating the width (length) of the vehicle 11. In the present embodiment, the traveling speed conditions can be classified and set for each vehicle information 54 described above. Thereby, notification can be performed at an appropriate timing for each vehicle.

  The items of the driver information 55 shown in the example of FIG. 10C are, for example, “vehicle ID”, “start date / time”, “end date / time”, “driver ID”, but are not limited thereto. . The vehicle ID is information for identifying the vehicle 11. The start date / time is date / time information when the driver corresponding to the driver ID starts using the vehicle 11. The end date / time is date / time information when the driver corresponding to the driver ID ends the use of the vehicle 11. The driver ID is information for identifying the driver.

  In this embodiment, drivers such as buses 11-2 and taxis 11-3 as shown in FIG. Therefore, by associating the vehicle and the driver with the driver information 55 as shown in FIG. 10C, the vehicle speed can be set for each driver, or the traveling speed condition can be set for each driver. As a result, an appropriate timing can be notified for each driver.

<Specific example of tabulation method and travel speed condition setting>
Next, a specific example of tabulation contents and travel speed condition setting using operation information in the management server 12 will be described with reference to the drawings. FIG. 11 is a diagram for explaining a method of counting areas in which sudden braking is likely to occur. In the example of FIG. 11, the horizontal axis indicates the distance (m) from a certain point (for example, the intersection A), and the vertical axis indicates the speed (km) with respect to the distance. Each line 90 on FIG. 11 shows a travel pattern based on the distance and speed for each vehicle 11 obtained from the operation information 51, and before each vehicle 11 obtained from the operation information 51 passes through the point (intersection A). The displacement of the speed for every predetermined section is shown.

  For example, in the predetermined area 91 close to the intersection A, the counting unit 42 counts the number of vehicles whose speed changes per unit distance width or more than the threshold, and determines the place where the sudden braking is likely to occur and its speed. Measure and count (aggregate) the values.

  In the example of FIG. 11, as a result of counting in each area, the number of vehicles considered to have suddenly braked 92 in the area 91-1 having a distance of 40 to 60 m and a speed of 10 to 30 km is different from other areas (for example, area 91- 2, 92-3). Therefore, based on the result shown in FIG. 11, for example, a specific sudden braking position and its traveling speed at each intersection are extracted, and notification based on the extracted information enables notification at an appropriate timing. Become.

<Running speed condition setting: first embodiment>
FIG. 12 is a diagram illustrating an example of a traveling speed condition in the first embodiment. FIG. 12A shows an area determined as a region where a predetermined behavior (rapid braking) with respect to the vehicle is generated, and FIG. 12B shows a speed band and a notification target corresponding to FIG. The relationship of distance is shown. The example of FIG. 12 shows the number of sudden braking occurrences at a certain point (for example, “in front of the central market” intersection).

  For example, as shown in FIG. 12, the traveling speed condition in the first embodiment is set by dividing the distance from the intersection into 20 m units and dividing the sudden brake generation start speed into 10 km units, but is limited to this. It is not a thing. In the first embodiment, the number of sudden braking occurrences is counted for each unit described above.

  In the first embodiment, as shown in the example of FIG. 12A, a certain number of times (for example, a threshold of 3 times) or more is set as an area where frequent braking occurs frequently, and the area where it occurs (distance from the intersection, sudden braking start) Speed). Here, since it is necessary to notify before sudden braking is actually necessary, for example, a traveling speed condition is set for a notification target of a distance 20 meters before (-20 meters) from a region where frequent sudden braking occurs (for example, FIG. 12 ( The shaded area shown in B). The range in front of the notification target is not limited to this. For example, the number of occurrences is compared with a threshold for each predetermined unit, an area equal to or greater than the threshold is acquired, and the area immediately before the acquired area is notified. It may be a target.

  This traveling speed condition includes position information and speed information. The traveling speed condition is set as a notification target based on a speed range having a predetermined width.

  In the first embodiment, the same zone is targeted for the speed band, but the speed zone is not limited to this. For example, the speed is reduced by 5 km / h (−5 km / h) than the speed corresponding to the sudden braking frequent occurrence area. The traveling speed condition may be set with the target speed being notified.

  The traveling speed condition 53 set in the first embodiment is stored in the storage unit 46 and transmitted to each vehicle 11 in response to an inquiry from the in-vehicle device 20. The travel speed condition to be transmitted is information shown in FIG. 12B, but is not limited to this, and may be information shown in FIG. 12A, for example. When transmitting the information of FIG. 12 (A), the in-vehicle device 20 calculates the distance of “sudden braking frequent occurrence area−20 m” and the “speed corresponding to sudden braking frequent occurrence area−5 km / h”. Thus, the traveling state determination is performed.

  Also, in the first embodiment, the number of notifications can be set so that once notification is made, notification is not repeated many times before entering the intersection. Further, in the first embodiment, the notification content may be set as the traveling speed condition 51.

  Here, FIG. 13 is a diagram showing a specific example of the sudden braking occurrence information and the traveling speed condition. FIG. 13 (A) shows an example of sudden braking occurrence information obtained from the operation information 51, and FIG. 13 (B) shows a traveling speed condition corresponding to FIG. 13 (A).

  The items of sudden braking occurrence information shown in the example of FIG. 13A include, for example, “vehicle ID”, “date and time”, “intersection”, “entry direction”, “occurrence speed”, “deceleration width”, “from intersection” However, the present invention is not limited to this. The items of the traveling speed condition shown in the example of FIG. 13B include, for example, “ID”, “intersection”, “entry direction”, “distance”, “speed zone”, and the like, but are not limited thereto. It is not something.

  In the examples of FIGS. 13A and 13B, the approach direction is, for example, information indicating which direction the vehicle enters from a certain setting area (in the example of FIG. 13, the intersection in front of the central market). The generated speed is information indicating a speed when a sudden braking operation is generated, for example. The deceleration width is information indicating the deceleration width per unit time, for example. The distance from the intersection is information indicating the distance from the intersection when the sudden braking is generated. In addition, the distance and speed band information shown in FIG. 13 (B) is, for example, a table of travel measurement conditions as shown in FIG. 12 (B), but corresponds to FIG. 12 (B). is not. In the example of FIG. 13B, the speed band corresponding to the notification condition is set at an interval of 10 m, but the interval and the like are not limited to this.

  Information shown in FIG. 13A can be acquired from the operation information 51. Further, by setting the traveling speed condition as shown in FIG. 13B using the information shown in FIG. 13A, at least a danger notice is sent at the appropriate timing and position before arriving at the place. Can be done once. Therefore, according to the first embodiment, it is possible to make a notification that takes into account the proximity and speed to a certain area.

  Note that the data example applied in the present embodiment is not limited to this. For example, vehicle information storing vehicle type and vehicle weight corresponding to the vehicle ID, map information, years of experience of the driver (age May also be included), personality (whether it is a person who has a tendency to be short, timid, or speedy), weather information, and the like.

<Example of Processing in Running Condition Determination Unit 24 of In-Vehicle Device 20>
Next, an example of processing in the traveling state determination unit 24 of the in-vehicle device 20 taking the traveling speed condition shown in FIG. FIG. 14 is a flowchart illustrating an example of processing in the traveling state determination unit. In the following example, an example of determining the vehicle 11 driving with a high probability of sudden braking is shown as an example of the determination of the driving situation, but the determination method is not limited to this.

  In the example of FIG. 14, the traveling state determination unit 24 acquires the current position and speed from the operation information 32 or the like (S41). Note that the current position and speed include, for example, information on the position and speed of the vehicle 11 acquired in association with a certain setting area (for example, a distance from the intersection A and an approach direction).

  Next, the traveling state determination unit 24 compares the position and speed information obtained in the process of S41 with, for example, the traveling speed condition shown in FIG. 12B described above (S42). In the process of S42, for example, a travel speed condition corresponding to the proximity to the area indicated by the travel position of the vehicle 11 is acquired, and it is determined whether or not the travel speed corresponding to the travel position satisfies the travel speed condition. For example, in the processing of S42, for example, the current position is “sudden braking frequent occurrence area−20 m” on the basis of the distance from the intersection, and the speed (current speed) at that time is “speed corresponding to sudden braking frequent occurrence area”. Whether or not the vehicle 11 is a notification target can be determined based on whether it is “−5 km / h”, but the determination condition and the like are not limited to this.

  Next, the traveling state determination unit 24 determines whether or not the vehicle 11 is within the notification target range from the comparison result of the process of S42 (S43). If the vehicle 11 is within the notification target range (YES in S43), For example, it is determined that a message or the like for supporting safe driving is notified to the driver (S44). Further, when it is not within the notification target range (NO in S43), or after the process of S44, the process is terminated. 14 is repeatedly executed at a predetermined time interval (for example, 1 to 3 seconds) while the vehicle 11 is traveling.

<Running speed condition setting: second embodiment>
Next, a description will be given of a second embodiment for setting the traveling speed condition. FIGS. 15 and 16 are diagrams (No. 1 and No. 2) showing an example of the traveling speed condition in the second embodiment. In the example of FIG. 15, the number of times the vehicle 11 has traveled and the number of sudden brakings (the number of vehicles) in a distance range from a predetermined area (for example, an intersection) obtained from the counting result are shown.

  In the second embodiment, as in the first embodiment, as an example, the distance from the intersection is divided into units of 20 m, and the sudden brake generation start speed is divided into units of 10 km, and the total results as shown in FIG. 15 are acquired.

  In the second embodiment, the sudden braking occurrence ratio (for example, the number of times / the amount of traffic) is calculated for each unit described above. The calculation may be performed by the totaling unit 42 or the traveling speed condition setting unit 43. The calculated result is, for example, as shown in FIG.

  Here, in the second embodiment, for example, a sudden braking occurrence ratio of 3% or more is set as a sudden braking frequent occurrence area, and the occurrence area (distance from an intersection, sudden braking occurrence start speed) is acquired. Next, the traveling speed condition setting unit 43 sets the traveling speed condition as a notification target in an area 20 m before the area obtained in FIG. 16A (for example, the hatched portion in FIG. 16B). In the example of FIG. 16B, the speed zones are the same, but as described above, the speed of −5 km / h may be used as a condition, and other distances (for example, sudden braking frequent occurrence area −30 m) and A speed (for example, a speed corresponding to a region where heavy braking occurs frequently + 5 km / h) may be used as a condition.

  The traveling speed condition 53 set in the second embodiment is stored in the storage unit 46 as in the first embodiment, and is transmitted to each vehicle 11 in response to an inquiry from the in-vehicle device 20. Each vehicle 11 is determined based on the processing shown in FIG. 12 described above, and a message or the like for assisting safe driving is notified to the driver at an appropriate timing during traveling.

<Other embodiments>
In the first and second embodiments described above, the running speed condition is further set using the weather conditions (for example, clear, cloudy, rainy, snow), the results of counting for each vehicle type, vehicle weight, and time zone. Also good.

  For example, the totaling unit 42 classifies and aggregates the weather (for example, sunny, cloudy, rainy, snow, etc.) at the time of sudden braking when counting. The traveling speed condition setting unit 43 changes the distance to be notified according to, for example, the accumulated weather. For example, when the weather is clear or cloudy, the condition can be 20m before the area where frequent braking occurs, and when it is raining or snowing, the condition can be 40m.

  Similarly, the conditions may be changed depending on the vehicle type and the vehicle weight. Note that the vehicle type and the vehicle weight can be acquired based on the vehicle ID or the like as shown in the vehicle information 54 as shown in FIG. Examples of vehicle types include ordinary vehicles, medium-sized vehicles, large-sized vehicles, and extra-large vehicles, but are not limited thereto. For example, as an example of changing the condition based on the vehicle type, the condition is set such that the larger the vehicle is, the farther the distance from the intersection (reference point) is set in the area to be notified, but the present invention is not limited to this.

  Similarly, the conditions may be changed in the time zone. As an example of changing the condition based on the time zone, the condition is set so that the distance from the intersection (reference point) is longer in the middle of the night than in the daytime, but is not limited thereto.

  In the present embodiment, by the above-described method, it is possible to set a traveling speed condition in which different conditions are determined according to the degree of proximity to the setting area (for example, the distance from the sudden braking frequent occurrence area).

  Therefore, the vehicle 11 acquires an appropriate travel speed condition according to the driving situation (for example, weather, vehicle), etc., and responds to the proximity (distance) to the set area to the driver at an appropriate timing. You can be notified. In the present embodiment, the travel speed condition is set based on a wide speed range, so that an efficient setting considering the proximity to the area and the speed and notification at an appropriate timing can be performed. In addition, about a reference | standard, it is not limited to this. Each of the embodiments described above may be combined in part or in whole as necessary. In addition, the range of travel speed conditions (separation of numerical values) in each of the embodiments described above is not limited to this.

  As described above, according to the present embodiment, it is possible to notify a vehicle (driver or the like) at an appropriate timing that takes into account the proximity and speed to the area. In the present embodiment, for example, the number of sudden brakes is totaled for each distance from the intersection (for example, in units of 10 m), the most frequent speed zone (for example, in units of 10 km / h) is calculated for each distance, and notification is made for each distance. Set the driving speed condition to be performed. Further, in the present embodiment, when the vehicle 11 passes through a point with a certain point (intersection) as a reference, if the speed is to be notified, a corresponding notification is performed. Thereby, it can notify at an appropriate timing by notifying according to the tendency of the deceleration corresponding to sudden braking etc., for example.

  Moreover, this embodiment can notify not only a driver but an operation manager via the operation manager terminal 13. Thereby, the operation state for every vehicle to manage can be grasped more appropriately.

  Although the embodiments have been described in detail above, the invention is not limited to the specific embodiments, and various modifications and changes can be made within the scope described in the claims. Moreover, it is also possible to combine a part or all of each Example mentioned above.
