(First embodiment)
Hereinafter, a first embodiment of the disclosed technology will be described in detail with reference to the drawings.
FIG. 1 shows a vehicle warning system 10. The vehicle warning system 10 includes a plurality of vehicle devices 12 and a vehicle warning device 14. The plurality of vehicle devices 12 and the vehicle warning device 14 are connected via a wireless network 16. The vehicle warning system 10 is applied to an operation management system for commercial vehicles such as trucks and taxis.

  As shown in FIG. 2, the vehicle device 12 includes a control unit 18, a GPS receiving unit 20, an acceleration sensor 22, a timer 24, a sound output unit 26, an operation display unit 27, and a communication unit 28.

  The GPS receiving unit 20 receives a GPS signal from a GPS (Global Positioning System) satellite, and acquires information on the latitude and longitude of the current position of the vehicle on which the vehicle device 12 is mounted.

  The acceleration sensor 22 detects the acceleration of the vehicle on which the vehicle device 12 is mounted. The acceleration sensor 22 is, for example, a triaxial acceleration sensor, and detects acceleration in three directions of orthogonal XYZ axes.

  The timer 24 acquires the current date and time.

  The operation display unit 27 includes an operation button for performing various operations and a display device for displaying various messages such as an alarm message transmitted from the vehicle alarm device 14, and is configured by a touch panel, for example.

  Note that the audio output unit 26 and the operation display unit 27 correspond to an alarm unit in the disclosed technology.

  The control unit 18 includes the latitude and longitude acquired by the GPS receiving unit 20, the acceleration in the traveling direction of the vehicle detected by the acceleration sensor 22, the current date and time acquired by the timer 24, and the driver ID given in advance to the driver of the vehicle. It transmits to the vehicle warning device 14 every predetermined time as operation information.

  As shown in FIG. 3, the vehicle alarm device 14 includes an information update unit 30 and an alarm instruction unit 31. In addition, the vehicle alarm device 14 includes an area mesh information storage unit 36, a point information storage unit 38, an operation information storage unit 40, a driver activity area information storage unit 42, a sudden action occurrence information storage unit 44, and an alarm point information storage unit 46. , And a communication unit 48. The alarm instruction unit 31 includes a determination unit 32 and an instruction unit 34.

  As shown in FIG. 4, the regional mesh information storage unit 36 stores in advance regional mesh information 50 representing the correspondence relationship between the mesh code of the regional mesh, the start point latitude, the start point longitude, the end point latitude, and the end point longitude.

  The area mesh (area) is obtained by dividing the area into meshes of approximately the same size based on the latitude and longitude, and a mesh code is assigned in advance to identify the area mesh. Here, as an example, a case will be described in which a secondary mesh obtained by dividing an area into 10 km (about 5 minutes in units of latitude and longitude) is used. For this reason, the mesh code in the present embodiment is a secondary mesh code. In addition, not only a secondary mesh code but a primary mesh code and a tertiary mesh code may be used.

  As shown in FIG. 5, the area mesh 52 is represented by a rectangular area whose diagonal is a start point position represented by a start point latitude and a start point longitude and an end point position represented by an end point latitude and an end point longitude.

  As illustrated in FIG. 6, the point information storage unit 38 stores in advance point information 54 that indicates the correspondence between the point No, the start point latitude, the start point longitude, the end point latitude, and the end point longitude.

  The point is an area obtained by further dividing the area mesh. Similarly to the area mesh, the start point position represented by the start point latitude and the start point longitude and the end point position represented by the end point latitude and the end point longitude are diagonal lines. Represented by a rectangular area. As an example, the length of one side of the point is about 90 m (about 3 seconds in units of latitude and longitude). Each point is given a unique point No. in advance.

  As shown in FIG. 7, the operation information storage unit 40 stores operation information 56 including a driver ID, current date and time, acceleration, latitude of the current position, longitude of the current position, mesh code, and point No.

  As shown in FIG. 8, the driver activity area information storage unit 42 stores driver activity area information 58 including a driver ID, an activity period, a mesh code, the number of traffics, and a traffic frequency. Here, the target period is a period in which the number of times of traffic is counted and is one month in the example of FIG. 8, but is not limited to this, and may be several months or may be one year or more.

  The number of times of traffic represents the number of times the vehicle driven by the driver represented by the driver ID has passed (entered) the area of the regional mesh represented by the mesh code. The number of times of traffic is incremented by 1 every time a regional mesh represented by a mesh code is entered.

  The traffic frequency is, for example, “high” when the number of passes is A or more, “medium” when the number of passes is B or more and less than A, and “low” when the number of passes is 1 or more and less than B. FIG. 9 shows an example of the traffic frequency of each regional mesh. The way of dividing the traffic frequency is not limited to the way shown above.

  The information updating unit 30 increments the number of passes by 1 and determines whether the incremented number of passes belongs to “high”, “medium”, or “low”, and the traffic frequency is changed. Update to a new traffic frequency.

  As shown in FIG. 10, the sudden movement occurrence information storage unit 44 includes a point No, a mesh code of a regional mesh including a spot corresponding to the spot No, the number of sudden movements, the number of passages, a sudden movement occurrence rate, and a sudden movement occurrence rate. The sudden action occurrence information 60 including the rank is stored.

  The number of sudden movements is a value obtained by adding the number of sudden movements at the point indicated by the point No. for all the vehicles. The number of times of passing is a value obtained by adding the number of times of entering the point indicated by the point No. for all vehicles.

  The sudden action occurrence rate is a value obtained by dividing the number of sudden actions by the number of passes. The sudden action occurrence rates are ranked in descending order of sudden action occurrence rates.

  As shown in FIG. 11, the alarm point information storage unit 46 stores alarm point information 62 representing a correspondence relationship between the traffic frequency and the sudden action occurrence rate ranking of the alarm points to be alarmed. In the example of FIG. 11, when the traffic frequency is “high”, the points where the sudden action occurrence rate rank is 1 to 50 are set as the alarm points. In addition, when the traffic frequency is “medium”, the points where the sudden motion occurrence rate rank is 1 to 100 are alarm points, and when the traffic frequency is “low”, the sudden motion occurrence rate rank is 1 to 200. The points up to are set as warning points. It should be noted that points below the 201st place are not subject to warning.

  In regions where vehicles operate as bases (regions where the frequency of vehicle traffic is high), there is a tendency that the frequency of sudden actions such as sudden braking is lower than in other regions (regions where the frequency of vehicle traffic is low). This is because in areas where the vehicle is active as a base, the driver knows in advance the roads where sudden movements such as sudden braking may occur, and in such areas, he tries to drive safely in advance. It is thought that.

  For this reason, the warning instruction | indication part 31 makes the grade of the warning regarding sudden operation of a vehicle low, when the driving frequency in the present position of a vehicle is more than the predetermined reference | standard. In addition, when the traveling frequency at the current position of the vehicle is less than the reference, the warning instruction unit 31 increases the degree of warning related to the sudden operation of the vehicle and issues a warning instruction to the vehicle. That is, the warning instruction unit 31 decreases the number of warning points where the warning is executed in the region where the vehicle is frequently driven, and increases the number of warning points where the warning is executed in the region where the vehicle is frequently driven. In other words, the number of warning points is reduced in regions that are used to driving, and the number of warning points is increased in regions that are not used to driving. As a result, unnecessary alarms can be suppressed when alarming sudden operations such as sudden braking.

  Specifically, the alarm instruction unit 31 includes a determination unit 32 and an instruction unit 34. The determination unit 32 refers to the alarm point information 62, and based on the sudden action occurrence rate ranking included in the sudden action occurrence information 60 and the traffic frequency included in the driver activity area information 58, an alarm to alert the sudden action It is determined whether it is a point. The instruction unit 34 instructs the communication unit 48 to transmit an alarm message to be warned of sudden action to the vehicle device 12 when the determination unit 32 determines that the determination unit alarm point should be alarmed.

  The vehicle warning device 14 can be realized by a computer 70 shown in FIG. 12, for example. The computer 70 includes a CPU 72, a memory 74, and a nonvolatile storage unit 76, which are connected to each other via a bus 78.

  The storage unit 76 can be realized by an HDD (Hard Disk Drive), a flash memory, or the like. A storage unit 76 serving as a recording medium stores a vehicle warning program 80 for causing the computer 70 to function as the vehicle warning device 14. The CPU 72 reads out the vehicle warning program 80 from the storage unit 76, expands it in the memory 74, and sequentially executes processes included in the vehicle warning program 80.

  The vehicle warning program 80 includes an information update process 82, a warning point determination process 84, and a warning instruction process 86.

  The CPU 72 operates as the information update unit 30 illustrated in FIG. 3 by executing the information update process 82. Further, the CPU 72 operates as the determination unit 32 illustrated in FIG. 3 by executing the warning point determination process 84. Further, the CPU 72 operates as an instruction unit illustrated in FIG. 3 by executing the alarm instruction process 86.

  As a result, the computer 70 that has executed the vehicle warning program 80 functions as the vehicle warning device 14. The vehicle warning program 80 is an example of a vehicle warning program in the disclosed technology. In the above description, the vehicle alarm program 80 is stored in the storage unit 76 in advance. However, the vehicle alarm program 80 according to the disclosed technology is recorded on a recording medium such as a CD-ROM or a DVD-ROM. It is also possible to provide it in a certain form.

  The vehicle alarm device 14 can be realized by, for example, a semiconductor integrated circuit, more specifically, an ASIC (Application Specific Integrated Circuit) or the like.

  Next, the operation of the first embodiment will be described. First, the process performed by the vehicle apparatus 12 is demonstrated with reference to the flowchart shown in FIG. Note that the processing shown in FIG. 13 is executed every predetermined time, for example, every second.

  In step S <b> 100, the control unit 18 acquires latitude and longitude from the GPS receiving unit 20.

  In step S <b> 102, the control unit 18 acquires acceleration in the traveling direction of the vehicle from the acceleration sensor 22.

  In step S <b> 104, the control unit 18 acquires the current date and time from the timer 24.

  In step S <b> 106, the control unit 18 adds the driver ID to the acquired latitude and longitude, the acceleration in the traveling direction of the vehicle, and the current date and time to obtain operation information, and transmits the operation information to the vehicle alarm device 14 via the communication unit 28.

  In step S108, the control unit 18 determines whether or not an alarm message has been received from the vehicle alarm device 14 to alert the driver to be aware of a sudden operation such as a sudden brake. If an alarm message is received from the vehicle alarm device 14, the process proceeds to step S110. If an alarm instruction is not received from the vehicle alarm device 14, this routine ends.

  In step S110, the control unit 18 outputs the received warning message to the voice output unit 26, and outputs the warning message as a voice. An alarm message may be displayed on the operation display unit 27. As a result, the driver of the vehicle can be alerted to a sudden operation such as a sudden brake.

  Next, processing executed by the vehicle warning device 14 will be described with reference to a flowchart shown in FIG. The process shown in FIG. 14 is executed each time the communication unit 48 receives the operation information transmitted by the vehicle device 12. Below, the received operation information is called reception operation information.

  In step S <b> 200, the information update unit 30 updates the operation information 56 stored in the operation information storage unit 40. Specifically, the information update unit 30 refers to the regional mesh information 50 stored in the regional mesh information storage unit 36, and acquires the mesh code of the regional mesh to which the latitude and longitude included in the received operation information belongs. Further, the information update unit 30 refers to the point information 54 stored in the point information storage unit 38 and acquires the point No of the point to which the latitude and longitude included in the received operation information belongs. Then, the information update unit 30 stores the acquired mesh code and point No. in the operation information storage unit 40 in addition to the operation information received from the vehicle device 12. Thereby, every time operation information is received from each vehicle device 12, operation information for each driver ID is accumulated in the operation information storage unit 40 in the operation information storage unit 40.

  In step S202, the information update unit 30 determines whether or not a sudden operation has occurred in the vehicle driven by the driver with the driver ID included in the received operation information. Here, as an example, a case where the sudden movement is sudden braking will be described. Sudden braking refers to a case where there is a deceleration of a predetermined speed or more per unit time, and an example is a case where there is a deceleration of 10 km / s or more per second.

Therefore, the information update unit 30 refers to the operation information 56 stored in the operation information storage unit 40, and the acceleration A1 included in the latest operation information of the driver ID updated in step S200 and the latest of the driver ID. The acceleration A2 of the operation information immediately before the operation information is compared. Then, it is determined that sudden braking has occurred when the difference between the acceleration A1 and the acceleration A2 is −10 km ² / s or less.

  The information updating unit 30 proceeds to step S204 when determining that sudden braking has occurred, and proceeds to step S206 when determining that sudden braking has not occurred.

  In step S <b> 204, the information update unit 30 updates the sudden action occurrence information 60 stored in the sudden action occurrence information storage unit 44. Specifically, the information update unit 30 first increments the number of sudden movements of the point No where the sudden movement of the sudden movement occurrence information 60 has occurred by one. Next, the sudden action occurrence rate is calculated by dividing the sudden action number by the passing number, and updated. Then, the sudden action occurrence rate ranking is updated based on the new sudden action occurrence rate.

  In step S206, the information update unit 30 determines whether or not the regional mesh at the current position of the vehicle driven by the driver with the driver ID included in the received operation information has been switched, that is, whether or not the vehicle has entered a new regional mesh. to decide. Specifically, the information update unit 30 refers to the operation information 56, the mesh code included in the latest operation information corresponding to the driver ID included in the received operation information, and the previous one of the latest operation information. It is determined whether or not the mesh code included in the operation information is different. If the two mesh codes are different, it is determined that the regional mesh has been switched and the process proceeds to step S208. If both mesh codes are the same, it is determined that the regional mesh has not been switched and the process proceeds to step S210.

  In step S208, the information update unit 30 updates the driver activity area information 58 stored in the driver activity area information storage unit. Specifically, the information update unit 30 updates the driver activity area information corresponding to the driver ID included in the received operation information and the mesh code of the switched area mesh by incrementing by 1, and updates the updated information. The traffic frequency is determined based on the number of times of traffic. If the traffic frequency has changed, it is updated to a new traffic frequency. Note that when the traffic frequency is updated, the updated traffic frequency may be transmitted to the vehicle device 12 to instruct to notify the traffic frequency. In addition, when the updated traffic frequency is the previous traffic frequency, the notification is not given, and the updated traffic frequency allows the driver to recognize his / her own traffic frequency in the current traveling area, Attention is paid to movement.

  In step S210, the information update unit 30 determines whether or not the location of the vehicle driven by the driver ID included in the received operation information has been switched, that is, whether or not the vehicle has entered a new location. Specifically, the information update unit 30 refers to the operation information 56 stored in the operation information storage unit 40, and includes the point No included in the latest operation information corresponding to the driver ID included in the received operation information, It is determined whether or not the point No included in the operation information immediately before the latest operation information is different. And if both point No differs, it will be judged that the point changed and it will transfer to step S212, and if both point No is the same, it will be judged that the point has not changed and this routine will be complete | finished.

  In step S212, the information update unit 30 updates the sudden action occurrence information 60 stored in the sudden action occurrence information storage unit 44. Specifically, the number of passes of the sudden motion occurrence information corresponding to the point No of the point after switching is incremented by one. Next, the sudden action occurrence rate is calculated and updated by dividing the sudden action number by the updated number of passes, and the sudden action occurrence rate ranking is updated based on the updated sudden action occurrence rate.

  In step S <b> 214, the determination unit 32 reads the sudden motion occurrence rate ranking corresponding to the point No of the point after switching from the sudden motion occurrence information 60.

  In step S <b> 216, the determination unit 32 reads from the driver activity area information 58 the driver ID included in the received operation information and the traffic frequency of the mesh code to which the point after switching belongs.

  In step S218, the determination unit 32 determines whether an alarm is necessary for the point after switching based on the sudden movement occurrence rate ranking read in step S214 and the traffic frequency read in step S216. Specifically, the determination unit 32 refers to the alarm point information 62, and the sudden action occurrence rate order read in step S214 is included in the sudden action occurrence rate order corresponding to the traffic frequency read in step S216. Determine whether or not. If the sudden motion occurrence rate ranking read in step S214 is included in the sudden motion occurrence rate ranking corresponding to the traffic frequency read in step S216, it is determined that an alarm is necessary, and the process proceeds to step S220. On the other hand, if the sudden motion occurrence rate ranking read in step S214 is not included in the sudden motion occurrence rate ranking corresponding to the traffic frequency read in step S216, it is determined that an alarm is unnecessary and this routine is terminated.

  In step S220, an alarm message for calling attention to the sudden action is transmitted to the vehicle apparatus 12 that has transmitted the operation information to the vehicle alarm apparatus 14.

  Thereby, in the vehicle device 12, for example, as shown in FIG. 15, when the vehicle 90 driven by the driver ID included in the received operation information enters the warning target point 92, the driver of the vehicle 90 is warned. A message is uttered by voice or text. For this reason, the driver can recognize that there are many sudden movements at the point where the vehicle is traveling, and is alerted to the sudden movement.

  Also, set the higher rank of the sudden action rate ranking as a warning spot so that the number of warning spots decreases as the traffic frequency increases, and increase the number of warning spots as the traffic frequency decreases. It is set as an alarm point so that the lower ranks are also included. In other words, in areas that are used to driving, only warnings are given to points with high sudden movement rate rankings, and in cases where traffic frequency is low, that is, in regions that are not used to driving, warnings are also made to points with low sudden movement rate rankings. Unnecessary alarms can be suppressed.

(Second Embodiment)
Next, a second embodiment of the disclosed technique will be described. In addition, since the apparatus structure of the vehicle warning device 14 is the same as 1st Embodiment, description is abbreviate | omitted.

  In the second embodiment, a mode in which the user changes the traffic frequency of the driver activity area information 58 will be described.

  FIG. 16 shows a configuration of a vehicle device 12A according to the second embodiment. The vehicle device 12A shown in FIG. 16 is different from the vehicle device 12 shown in FIG. 2 in that a map information storage unit 29 is provided.

  The map information storage unit 29 includes map information including the same information as the map database for displaying the map on the operation display unit 27 and the regional mesh information 50 stored in the regional mesh information storage unit 36 of the vehicle warning device 14. Stored in advance.

  Next, the operation of the second embodiment will be described. First, the process performed by the vehicle apparatus 12 is demonstrated with reference to the flowchart shown in FIG. The process shown in FIG. 17 is different from the process shown in FIG. 13 in that the processes in steps S112 to S116 are added. Since the other processes are the same as those in the first embodiment, the description thereof is omitted.

  As shown in FIG. 17, in step S112, the control unit 18 determines whether or not there is a request for changing the traffic frequency. The user of the vehicle device 12 can operate the operation display unit 27 to instruct a change in the traffic frequency of the driver activity area information corresponding to the driver ID of the driver of the vehicle on which the vehicle device 12 is mounted.

  In step S114, the control unit 18 requests the vehicle warning device 14 to transmit the driver activity area information corresponding to the driver ID of the driver of the vehicle device 12A via the communication unit 28.

  In step S116, it is determined whether or not driver activity area information has been received from the vehicle warning device 14. If received, the process proceeds to step S118. If not received, the process waits until it is received.

  In step S118, the control unit 18 executes a traffic frequency setting process. Specifically, the control unit 18 reads map information from the map information storage unit 29 and displays it on the operation display unit 27. At this time, as shown in FIG. 18, the map is divided and displayed by the area mesh 94, and the traffic frequency of the received driver activity area information is shaded and displayed, so that the difference in the traffic frequency for each area mesh is displayed. Is displayed so that can be recognized.

  The user of the vehicle device 12 </ b> A operates the operation display unit 27 to select by touching the regional mesh whose traffic frequency is to be changed. As shown in FIG. 18, the selected regional mesh 94A is highlighted by being displayed as a thick frame as an example or displayed in a color different from other regional meshes.

  When the user performs a predetermined operation for instructing the change of the traffic frequency, the control unit 18 causes the operation display unit 27 to display a traffic frequency setting screen 96 as shown in FIG. As shown in FIGS. 18 and 19, the traffic frequency of the selected regional mesh 94 is set to “no travel”. In FIG. 19, the radio button 96A for “no running” is selected and displayed as a black circle. For example, to set the traffic frequency to “medium frequency”, the radio button of “medium frequency” is touched. As a result, the traffic frequency is changed to “medium frequency” as shown in the setting screen 98, and the traffic frequency of the selected regional mesh 94A is changed to “medium frequency” as shown in FIG.

  In step S <b> 120, the control unit 18 transmits the changed traffic frequency to the vehicle alarm device 14 via the communication unit 28.

  Next, processing executed by the vehicle alarm device 14 will be described with reference to a flowchart shown in FIG. The process shown in FIG. 21 is different from the process shown in FIG. 14 in that the processes in steps S222 to S228 are added. The other processes are the same as those in the first embodiment, and the description thereof will be omitted.

  In step S222, the information update unit 30 determines whether or not there is a request from the vehicle device 12 to transmit the driver activity area information. If there is a request, the process proceeds to step S224. This routine ends.

  In step S224, the information update unit 30 reads out the driver activity area information of the requested driver ID from the driver activity area information storage unit 42 and transmits it to the vehicle device 12 via the communication unit 48.

  In step S226, it is determined whether or not the changed traffic frequency is received from the vehicle device 12. If the changed traffic frequency is received, the process proceeds to step S228, and the changed traffic frequency is not received. If so, wait until it is received.

  In step S228, the corresponding traffic frequency of the driver activity area information 58 stored in the driver activity area information storage unit 42 is updated to the changed traffic frequency received in step S226.

  Thus, the change of the traffic frequency is accepted, and the driver activity area information is updated with the accepted traffic frequency after the change. Therefore, the user can change the traffic frequency of the regional mesh whose traffic frequency is desired to be changed to a desired traffic frequency. For this reason, for example, recently, the traffic frequency is “no travel” and the traffic frequency is changed to “medium frequency” for areas that have been used frequently in the past. As a result, the number of alarm points can be reduced. Thereby, useless warning can be suppressed.

  In the above description, the sudden braking has been described as an example of the sudden action. However, the disclosed technology can be applied to sudden acceleration and sudden steering.

  The vehicle warning system 10 in the disclosed technology may be applied not only to a business operation management system such as a truck or a taxi, but also to a general vehicle. For example, the vehicle warning system 10 can be applied to a general vehicle by incorporating the vehicle device 12 in the car navigation system.

  In addition, when considering the frequency of vehicle traffic, some drivers drive carefully on frequent roads, while others are distracted if they get used to traveling on frequent roads. For drivers who have become distracted because they are too used to traveling on the roads they frequently pass, it is possible to suppress the distracted state of the driver by increasing the frequency of warnings.

  In order to make it possible to suppress the driver's distraction state, for example, the following alarm instruction unit may be provided. The alarm instruction unit increases the degree of alarm regarding the sudden operation of the vehicle when the traveling frequency at the current position of the vehicle is equal to or higher than a predetermined reference, and instructs the vehicle to issue an alarm. Further, the alarm instruction unit instructs the vehicle to issue an alarm by lowering the degree of alarm regarding the sudden operation of the vehicle when the traveling frequency at the current position of the vehicle is less than the reference.

  Regarding the above embodiment, the following additional notes are disclosed.
