In each drawing, the same or corresponding elements are designated by the same reference numerals, and duplicate explanations are omitted as necessary for the sake of clarity of explanation. In the following, the vehicle equipped with the driving support device according to each embodiment will be referred to as "own vehicle". Further, the "vehicle-mounted device" in the present specification does not need to be incorporated in the vehicle, and includes a device that can be arbitrarily removed from the vehicle, such as a portable terminal.

<Embodiment 1>
FIG. 1 is a block diagram showing a configuration of an operation support device 1 according to the first embodiment. The driving support device 1 is, for example, an information processing device such as an in-vehicle device mounted on an automobile (own vehicle). It is assumed that the own vehicle is equipped with a camera capable of photographing at least one of the front and the rear, and an image of the own vehicle while traveling is recorded.

Further, it is assumed that the own vehicle is traveling on a predetermined road at a predetermined speed or more, for example, 60 km / h or more, and one or more other vehicles (other automobiles) are traveling in the vicinity. It is assumed that the other vehicle is traveling in the front, rear, side (lateral direction), diagonal direction, etc. of the own vehicle.

The driving support device 1 includes an acquisition unit 11, a selection unit 12, a collection unit 13, a determination unit 14, and a notification unit 15. The acquisition unit 11 acquires a peripheral image taken from the traveling own vehicle. It is assumed that the peripheral image includes one or more other vehicles. The selection unit 12 selects a candidate vehicle that may be driving with respect to its own vehicle from among other vehicles included in the peripheral image.

For example, the selection unit 12 analyzes the peripheral image to extract the shape of the other vehicle, and calculates the distance between the own vehicle and the other vehicle based on the position in the image of the other vehicle. Then, the selection unit 12 determines that there is a possibility that the other vehicle is driving with respect to the own vehicle when the inter-vehicle distance is equal to or less than the predetermined distance, and the other vehicle is driving with the other vehicle. Select as a potential candidate vehicle. The selection unit 12 may select two or more candidate vehicles. The method of selecting the selection unit 12 is not limited to this, and for example, the fanning operation determination process described in Patent Document 1 may be applied.

Here, the fanning driving refers to a driving state intentionally performed by the driver of another vehicle, that is, a driving state in which the vehicle operation of the other vehicle is under the control of the driver, and is referred to as dangerous driving such as drunk driving. Is different. Therefore, even if the driver of the own vehicle tries to drive away from the other vehicle, the driver of the other vehicle intentionally follows the driving operation or keeps the driver away from the other vehicle. Includes conditions such as those listed in the operating conditions. That is, the road rage includes a state in which another vehicle intentionally follows the own vehicle (repeated rapid approach, etc.).

When a candidate vehicle is selected by the selection unit 12, the collecting unit 13 collects detailed information about the candidate vehicle. Detailed information includes an enlarged image of a specific area of the candidate vehicle, an analysis result of the enlarged image, a time during which the distance between the candidate vehicle and the own vehicle is maintained within a predetermined distance, and the number of times the distance between vehicles is within a predetermined distance. Etc., but are not limited to these. The collecting unit 13 may aggregate the collected various information and generate it as detailed information in the candidate vehicle.

The determination unit 14 acquires a determination result as to whether or not the candidate vehicle is driving in a hurry based on the detailed information. Here, the determination unit 14 inputs the detailed information collected this time into the "judgment model of the driving operation" learned in advance based on the detailed information, and acquires the output of the determination model as the determination result. Is desirable. As a result, it is possible to make a more accurate determination that reflects the past cases of road rage. In this case, the determination model may be held inside or outside the driving support device 1.

When the determination result by the determination unit 14 indicates that the candidate vehicle is driving in a hurry, the notification unit 15 notifies the outside of the notification information including the detailed information. Here, the outside may be, for example, a police force or another institution, and may have equipment capable of notifying by wireless communication. Then, for the notification, a communication means such as a telephone or an e-mail can be used.

FIG. 2 is a flowchart showing the flow of the driving support method according to the first embodiment. First, the acquisition unit 11 acquires a peripheral image taken from the traveling own vehicle (S11). Next, the selection unit 12 selects a candidate vehicle that may be driving with respect to the own vehicle from among the other vehicles included in the peripheral image (S12).

Then, after step S12, that is, when the candidate vehicle is selected by the selection unit 12, the collection unit 13 collects detailed information about the candidate vehicle (S13). Subsequently, the determination unit 14 acquires a determination result as to whether or not the candidate vehicle is driving in a fanning manner based on the detailed information (S14). After that, when the determination result in step S14 indicates that the candidate vehicle is driving in a hurry, the notification unit 15 notifies the outside of the notification information including the detailed information (S15).

As described above, in the present embodiment, after selecting a candidate vehicle that may be driving by driving from the peripheral image in step S12, detailed information that can be determined in detail about the candidate vehicle is collected. Then, based on the collected detailed information, it is determined again whether or not the candidate vehicle is driving in a hurry. Therefore, it is possible to improve the accuracy of determining whether or not another vehicle is driving with respect to the own vehicle.

In addition, if it is determined that the candidate vehicle is driving in a hurry, it can be notified to the outside including detailed information about the candidate vehicle. In addition, appropriate information can be notified. Therefore, it is possible to take appropriate measures at the notification destination organization and support the driver of the own vehicle.

The operation support device 1 includes a processor, a memory, and a storage device as a configuration (not shown). Further, the storage device stores a computer program in which the processing of the driving support method according to the present embodiment is implemented. Then, the processor reads the computer program from the storage device into the memory and executes the computer program. As a result, the processor realizes the functions of the acquisition unit 11, the selection unit 12, the collection unit 13, the determination unit 14, and the notification unit 15.

Alternatively, the acquisition unit 11, the selection unit 12, the collection unit 13, the determination unit 14, and the notification unit 15 may each be realized by dedicated hardware. Further, a part or all of each component of each device may be realized by a general-purpose or dedicated circuitry, a processor, or a combination thereof. These may be composed of a single chip or may be composed of a plurality of chips connected via a bus. A part or all of each component of each device may be realized by the combination of the circuit or the like and the program described above. Further, as a processor, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an FPGA (field-programmable gate array), an ECU (Electronic Control Unit), or the like can be used.

Further, when a part or all of each component of the driving support device 1 is realized by a plurality of information processing devices and circuits, the plurality of information processing devices and circuits are centrally arranged in the own vehicle. It may be distributed or distributed. Further, the function of the determination model of the driving support device 1 may be provided in the SAAS (Software as a Service) format.

<Embodiment 2>
The second embodiment is a modification of the first embodiment described above, and relates to a driving support system which is an information system for supporting the driver of the own vehicle described above. FIG. 3 is a block diagram showing a configuration of the driving support system 2000 according to the second embodiment. The driver assistance system 2000 includes an in-vehicle device 1a and a server 2, each of which is connected via a network N. The network N is a communication network connected to an Internet line via a wireless communication network.

The in-vehicle device 1a is an example of a driving support device mounted on the own vehicle, and has the same reference numerals as those of the driving support device 1 described above, and detailed description thereof will be omitted. The in-vehicle device 1a includes an acquisition unit 11, a selection unit 12, a collection unit 13, a notification unit 15, a transmission unit 16, and a reception unit 17. The transmission unit 16 transmits the detailed information collected by the collection unit 13 to the server 2 via the network N. The receiving unit 17 receives the result of determination as to whether or not the candidate vehicle determined based on the detailed information on the server 2 is driving. That is, it can be said that the receiving unit 17 acquires (receives) the determination result from the outside of the device, and the determination unit 14 described above acquires the determination result from the inside of the device. When the result of the determination received from the server indicates that the candidate vehicle is driving, the notification unit 15 notifies the outside of the notification information including the detailed information. At this time, the notification unit 15 may make a notification via the network N, or may make a notification via a wireless telephone line network (not shown) or the like. Alternatively, the notification unit 15 may be provided outside the vehicle (for example, the server 2 or the like).

The server 2 is a computer system composed of one or more information processing devices, and can also be called a driving support device according to the present embodiment. The server 2 includes a receiving unit 21, a determination unit 22, and a notification unit 23. The receiving unit 21 receives detailed information from the transmitting unit 16 via the network N. The determination unit 22 determines whether or not the candidate vehicle is driving in a fanning manner based on the detailed information received from the in-vehicle device 1a. Here, the determination unit 22 may input the detailed information collected this time into the "judgment model of the driving operation" learned in advance based on the detailed information, and use the output of the determination model as the determination result. desirable. As a result, it is possible to make a more accurate determination that reflects the past cases of road rage. In this case, it is assumed that the determination model is typically held inside the server 2 and at least outside the in-vehicle device 1a. The notification unit 23 returns the determination result by the determination unit 22 to the in-vehicle device 1a via the network N. Therefore, it can be said that the transmission unit 16 described above transmits the detailed information collected by the collection unit 13 to the server 2 provided with the determination model. Further, it can be said that the above-mentioned receiving unit 17 receives the output when the detailed information is input to the determination model in the server 2 from the server 2 as the determination result.

FIG. 4 is a sequence diagram showing the flow of the driving support method according to the second embodiment. First, since steps S11 to S13 are the same as those in FIG. 2 described above except that the in-vehicle device 1a is executed, detailed description thereof will be omitted. Next, the transmission unit 16 transmits the detailed information collected by the collection unit 13 to the server 2 via the network N (S21).

Subsequently, the receiving unit 21 of the server 2 receives detailed information from the transmitting unit 16 via the network N. Then, the determination unit 22 determines whether or not the candidate vehicle is driving in a fanning manner based on the detailed information received from the in-vehicle device 1a (S22). After that, the notification unit 23 returns the determination result to the vehicle-mounted device 1a via the network N (S23).

Then, the receiving unit 17 of the in-vehicle device 1a receives the determination result from the server 2. When the result of the determination received from the server indicates that the candidate vehicle is driving, the notification unit 15 notifies the outside of the notification information including the detailed information (S15).
As described above, the in-vehicle device 1a does not necessarily have to be provided with the notification unit 15. In that case, for example, the notification unit 23 of the server 2 may execute the equivalent of step S23 instead of step S23. That is, when the result of the determination indicates that the candidate vehicle is driving in a hurry, the notification unit 23 of the server 2 notifies the outside of the notification information including the detailed information. Alternatively, in addition to the in-vehicle device 1a and the server 2, there may be a notification device that notifies the police or the like. In that case, the notification unit 23 of the server 2 may set the transmission destination of step S23 as the notification device.

As described above, in the present embodiment, since it is possible to determine whether or not another vehicle is driving the own vehicle on the server side, the processing load on the in-vehicle device is reduced as compared with the first embodiment. can. Therefore, more advanced determination processing can be executed on the server 2, and determination accuracy can be improved. Further, as in the first embodiment, since appropriate information can be notified, it is possible to support the driver of the own vehicle.

The server 2 includes a processor, a memory, and a storage device as a configuration (not shown). Further, the storage device stores a computer program in which the processing of the driving support method according to the present embodiment is implemented. Then, the processor reads the computer program from the storage device into the memory and executes the computer program. As a result, the processor realizes the functions of the receiving unit 21, the determination unit 22, and the notification unit 23.

Alternatively, the receiving unit 21, the determination unit 22, and the notification unit 23 may each be realized by dedicated hardware. Further, a part or all of each component of each device may be realized by a general-purpose or dedicated circuitry, a processor, or a combination thereof. These may be composed of a single chip or may be composed of a plurality of chips connected via a bus. A part or all of each component of each device may be realized by the combination of the circuit or the like and the program described above. Further, as a processor, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an FPGA (field-programmable gate array), an ECU (Electronic Control Unit), or the like can be used.

Further, when a part or all of each component of the server 2 is realized by a plurality of information processing devices and circuits, the plurality of information processing devices and circuits may be centrally arranged or distributed. May be done. For example, the information processing device, the circuit, and the like may be realized as a form in which each is connected via a communication network, such as a client-server system and a cloud computing system. Further, the function of the server 2 may be provided in the SaaS (Software as a Service) format.

The in-vehicle device 1a has the same hardware configuration as the driving support device 1 described above, and the processor reads a computer program from the storage device into the memory and executes the computer program. As a result, the processor realizes the functions of the acquisition unit 11, the selection unit 12, the collection unit 13, the notification unit 15, the transmission unit 16, and the reception unit 17.

<Embodiment 3>
Here, the problem to be solved by this embodiment will be described in detail.
In recent years, many drivers have been hit by road rage, which has become a great stress factor. In addition, there are reports of malicious incidents such as relentless pursuit leading to a major accident. And although the police are strengthening the crackdown on road rage, not all road rage has been detected, so the damage caused by road rage is still a social problem.

Here, typical measures that a driver who has been damaged by road rage can take include shooting evidence videos and reporting to the police. However, it is difficult for the driver to make a report while driving in real time from the viewpoint of safety. Therefore, it is necessary to make a new report after stopping the own vehicle. However, it can be said that there is psychological resistance to reporting in the first place. Therefore, reporting is a heavy burden on the driver. There is also the problem that there are few measures that the driver can take while suffering from road rage.

Therefore, it is possible to make a prompt report during or immediately after being damaged by driving, the driver can make a report without any special action while driving, and effective information can be prepared without excess or deficiency. Etc. are required.

Therefore, the third embodiment is a specific embodiment of the first embodiment described above, and the following describes a method for solving at least a part of the above-mentioned problems.

FIG. 5 is a diagram for explaining the concept of the driving support system 3000 according to the third embodiment. The driving support system 3000 indicates a situation in which the running own vehicle 4 is being driven by another vehicle 5 behind. Further, it is assumed that the own vehicle 4 is equipped with the in-vehicle device group 40 according to the present embodiment and can communicate with the communication device 31 of the notification destination 3 via the communication network N1. The communication network N1 shall be a communication line including at least a mobile phone line network or a wireless communication network. The notification destination 3 is, for example, the police or the like, and the operator 32 can receive the notification information from the in-vehicle device group 40 by the communication device 31. In the following description, as a premise, the own vehicle 4 is in a state where a predetermined road (for example, an expressway) is at a predetermined speed or more, for example, 60 km / h or more, and excessive acceleration / deceleration is not repeated. It is assumed that the vehicle is traveling 0.3 m or more inside from the outside line.

FIG. 6 is a block diagram showing a configuration of an in-vehicle device group 40 mounted on the own vehicle according to the third embodiment. The in-vehicle device group 40 includes an illuminance sensor 41, a microphone 42, a notification unit 43, a camera unit 44, a GPS (Global Positioning System) information receiver 45, a communication device 46, a speed measuring instrument 47, and manual notification. It is equipped with a button 48.

The illuminance sensor 41 is a sensor that detects the illuminance indicating the brightness of the light that illuminates the periphery of the own vehicle, and outputs the detected illuminance to the notification unit 43. For example, the illuminance sensor 41 can detect that a passing has been received from another vehicle toward the own vehicle.

The microphone 42 is a device that collects sounds around the own vehicle, and outputs the collected sound information to the reporting unit 43. For example, the microphone 42 can detect that the horn is sounded from another vehicle.

The GPS information receiver 45 outputs position information (GPS information) based on GPS signals received from GPS satellites to the reporting unit 43.

The communication device 46 is a device for transmitting and receiving wireless signals to and from the outside such as the communication network N1. The communication device 46 transmits a wireless signal to the communication network N1 or the like in response to an instruction from the notification unit 43, and outputs information based on the wireless signal received from the communication network N1 or the like to the notification unit 43.

The speed measuring instrument 47 is a device that measures the traveling speed of the own vehicle and outputs it to the reporting unit 43. The speed measuring instrument 47 may be realized by a dedicated unit, or the vehicle speed information used in a speedometer or the like inside the automobile may be used.

The manual notification button 48 is a button that can be pressed by a passenger such as a driver of the own vehicle, and when the button is pressed, a signal to that effect is output to the notification unit 43. For example, when the driver or the like of his / her own vehicle feels that he / she is suffering from the damage of driving by driving from another vehicle, he / she can start the collection process of detailed information by pressing the manual notification button 48. Therefore, it is possible to easily notify the notification destination 3 by the intention of the driver or the like.

The camera unit 44 includes a front-rear camera 441, a camera ECU 442, and an HDD (Hard Disk Drive) 443. The front-rear camera 441 is a group of photographing devices for photographing at least the front and rear peripheral images of the own vehicle. Including camera equipment. Further, the front-rear camera 441 may include a camera device for photographing the side (lateral direction) of the own vehicle. Alternatively, the front-rear camera 441 may be a camera device capable of shooting 360 degrees.

The HDD 443 is a recording medium for recording video data which is a group of peripheral images continuously taken by the front and rear cameras 441. The recording medium is not limited to the HDD.

The camera ECU 442 is a control device that controls the front and rear cameras 441 and the HDD 443. The camera ECU 442 acquires a peripheral image from the front-rear camera 441 or the HDD 443 and outputs the peripheral image to the notification unit 43.

The notification unit 43 is an example of an in-vehicle device and a driving support device, and includes a storage unit 430, an acquisition unit 431, a primary determination unit 432, a collection unit 433, a secondary determination unit 434, a notification information generation unit 435, and a mail function unit 436. A telephone function unit 437 is provided.

The storage unit 430 is a storage device that stores the determination model 4301, the map information 4302, and the like. The determination model 4301 is a program module or model formula in which a process of inputting detailed information about the candidate vehicle, performing a predetermined calculation using the set parameters, and outputting the calculation result is implemented. For example, the determination model 4301 is a mathematical model in which each data of detailed information is used as an element of input data, and a predetermined parameter (weighting coefficient) is used for each input data to perform a calculation. The determination model 4301 may be represented by a neural network, a support vector machine, or the like. Further, in the present embodiment, the output result of the determination model 4301 is used as a secondary determination result as to whether or not the candidate vehicle is driving with respect to the own vehicle. Map information 4302 is general map data including road information.

The acquisition unit 431 is an example of the acquisition unit 11 and acquires a peripheral image from the camera ECU 442.

The primary determination unit 432 analyzes the peripheral image acquired by the acquisition unit 431 and makes a primary determination as to whether or not there is a possibility that another vehicle included in the peripheral image is driving. The primary determination unit 432 is an example of the selection unit 12, and the candidate vehicle may be selected by the selection method described above in the first embodiment. Here, it is assumed that the boundary line on the own vehicle side and the threshold value of the predetermined distance in the peripheral image are predetermined. In that case, for example, first, the primary determination unit 432 analyzes the peripheral image and identifies the area of one or more other vehicles. Then, the primary determination unit 432 calculates the distance between each specified area and the boundary line as the inter-vehicle distance, and when the inter-vehicle distance is equal to or less than a predetermined distance, determines that the other vehicle is a candidate vehicle. That is, the primary determination unit 432 makes a primary determination that there is a possibility that the other vehicle is being driven by the own vehicle.

Further, the primary determination unit 432 selects the other vehicle as a candidate vehicle when the distance between the other vehicle and the own vehicle becomes a predetermined distance or less after the other vehicle interrupts in front of the own vehicle. You may do it. This makes it possible to prevent leakage of candidate vehicles that are likely to be driven by road rage. Alternatively, the primary determination unit 432 may select the other vehicle as a candidate vehicle when the lateral distance between the other vehicle and the own vehicle continues to be equal to or less than a predetermined distance for a certain period of time or longer. This also makes it possible to prevent leakage of candidate vehicles that are likely to be driven by road rage. The lateral inter-vehicle distance is determined when the front-rear camera 441 includes a camera device that captures the lateral periphery of the own vehicle, or is reflected in a part of the peripheral image (for example, a side mirror) captured from the front or the rear. It can be calculated from the area of other vehicles.

The collection unit 433 is an example of the collection unit 13, and collects and generates collection information regarding a candidate vehicle when it is determined by the primary determination unit 432 that there is a possibility of road rage. For example, the collecting unit 433 collects information related to the position of the own vehicle. The position-related information is, for example, GPS information (coordinates, etc.) indicating the current position of the own vehicle, the name of the road on which the vehicle is traveling, the distance from the nearest IC (InterChange), or the like. For example, the collecting unit 433 acquires GPS information from the GPS information receiver 45, refers to the map information 4302 of the storage unit 430, and specifies the road name or the like to collect the GPS information.

In addition, the collecting unit 433 acquires and analyzes a detailed image of the candidate vehicle. In other words, the collecting unit 433 collects as detailed information an image taken by enlarging a specific area of the candidate vehicle among the peripheral images. For example, the collecting unit 433 identifies the area of the license plate of the candidate vehicle from the peripheral image, and instructs the camera ECU 442 to focus on the specified area. The camera ECU 442 causes the front and rear cameras 441 to focus in response to an instruction, and causes the front and rear cameras 441 to take a detailed image (enlarged image) of the license plate. The collection unit 433 analyzes the detailed image of the photographed license plate and converts the number into text to obtain detailed information. Alternatively, the collecting unit 433 may specify the face area of the driver of the candidate vehicle from the peripheral image and instruct the camera ECU 442 to focus on the specified face area. In that case, the collecting unit 433 uses the photographed face image of the driver of the candidate vehicle as detailed information. The collecting unit 433 may use another area as a specific area. As a result, it is possible to provide a sufficient amount of information to the notification destination 3 while improving the accuracy of the secondary determination.

In addition, the collecting unit 433 measures information related to the inter-vehicle distance. For example, the collecting unit 433 counts (measures) the number of times the distance between the candidate vehicle and the own vehicle becomes equal to or less than the predetermined distance from a plurality of peripheral images in a predetermined period, and collects it as detailed information. Alternatively, the collecting unit 433 collects as detailed information the information in which the inter-vehicle distance is equal to or less than a predetermined distance and the duration is measured. Alternatively, the collector 433 may measure both the number of times and the duration. Further, the collecting unit 433 may calculate the inter-vehicle distance and the relative speed by using the white line or the like in the peripheral image and use it as information related to the inter-vehicle distance. Here, a TOF (Time-Of-Flight) camera, LiDAR (Light Detection And Ranging), or the like may be used for the measurement.

Further, the collecting unit 433 collects at least one of the light or the sound detected from the periphery of the own vehicle as detailed information. For example, the collecting unit 433 may measure the number of times the own vehicle has been passed by another vehicle based on the output from the illuminance sensor 41, and may use it as detailed information. Further, the collecting unit 433 may measure the volume and the number of times that the own vehicle honks from another vehicle by the output from the microphone 42, and may use it as detailed information.

Further, when the telephone number, the driver's name, etc. of the driver of the own vehicle or the identification information of the driver or the own vehicle is registered in advance in the storage unit 430, the collection unit 433 collects these information from the storage unit 430. It may be collected and included in the detailed information. As a result, more accurate information can be transmitted to the notification destination 3.

The collection unit 433 also performs the same collection process as above even when the manual notification button 48 is pressed.

The secondary determination unit 434 inputs detailed information to the determination model 4301 of the driving operation learned in advance based on the detailed information in the past, and acquires the output of the determination model as the (secondary) determination result. That is, the secondary determination unit 434 makes a secondary determination as to whether or not the candidate vehicle is being driven by the road rage based on the detailed information. Then, it is desirable that the determination model 4301 is machine-learned in advance. That is, the learned determination model 4301 performs the secondary determination by comprehensively considering the position-related information of the own vehicle, the detailed image of the candidate vehicle, the measured value related to the inter-vehicle distance, and the like. Therefore, the determination accuracy is further improved.

The secondary determination unit 434 may use a determination model in which at least a part of the following algorithm is implemented. For example, the secondary determination unit 434 determines that the own vehicle 4 is maintained at a distance of less than 5 m from the other vehicle 5 for 3 minutes or more, or the distance between vehicles approaches and leaves within 5 minutes. When it is repeated 5 times or more, it may be determined that the other vehicle 5 is driving in a fan. Further, the secondary determination unit 434 determines that the other vehicle 5 is driving in a rage when the own vehicle 4 is maintained in a state of less than 0.5 m laterally from the other vehicle 5 for 1 minute or more. It is also good. Further, the secondary determination unit 434 may determine that the other vehicle 5 is driving in a fanned manner when the own vehicle 4 is passed by the other vehicle 5 five times or more within one minute. Further, the secondary determination unit 434 may determine that the other vehicle 5 is driving in a hurry when the own vehicle 4 is honked by the other vehicle 5 three times or more within one minute. .. In the determination model, the speed, distance, time, and number of times in the above secondary determination can be set as parameters, and the settings may be arbitrarily changed by the user or the parameters may be updated by machine learning.

When the determination result of the secondary determination unit 434 indicates that the other vehicle 5 is driving in a hurry, the notification information generation unit 435 generates notification information including detailed information. For example, the notification information generation unit 435 includes, in addition to the above-mentioned detailed information, a message indicating that the user has suffered a road rage and that video data is stored in the notification information. When the notification method is e-mail, the notification information generation unit 435 outputs the notification information in text form to the mail function unit 436. At this time, the e-mail address of the notification destination may be specified. The e-mail address of the notification destination is stored in the storage unit 430 in advance, and may be all or an arbitrarily selected part of the plurality of notification destinations. When the notification method is a telephone, the notification information generation unit 435 converts the notification information into voice information by voice synthesis and outputs it to the telephone function unit 437. At this time, the telephone number of the notification destination may be specified. The telephone number of the notification destination is stored in the storage unit 430 in advance, and may be one arbitrarily selected from a plurality of notification destinations. The notification information generation unit 435 does not necessarily have to collectively output all the notification information to the telephone function unit 437. For example, the notification information generation unit 435 initially instructs the telephone function unit 437 to make a call to the telephone number of a predetermined notification destination, and responds to a question from the operator 32 received by the communication device 31 to the notification information generation unit 435. May convert the corresponding information among the notification information into voice and output it via the telephone function unit 437.

The mail function unit 436 uses the notification information output from the notification information generation unit 435 as the body of the mail, and transmits an e-mail to the designated mail address of the notification destination via the communication network N1 using the communication device 46. ..

The telephone function unit 437 makes a call to the telephone number of the notification destination instructed by the notification information generation unit 435 via the communication network N1 using the communication device 46, and utters the voice information of the notification information. Further, the telephone function unit 437 outputs the contents received from the operator 32 via the communication device 31, the communication network N1 and the communication device 46 to the notification information generation unit 435.

FIG. 7 is a block diagram showing a hardware configuration of the notification unit 43 according to the third embodiment. The notification unit 43 includes a storage device 401, a control unit 402, a memory 403, and an IF (Interface Face) unit 404. The storage device 401 is a non-volatile storage device such as a hard disk or a flash memory. The storage device 401 stores the determination model 4011 and the driving support program 4012. The determination model 4011 corresponds to the determination model 4301 described above, and the parameter 40111 can be set and changed from the outside. The driving support program 4012 is a computer program in which the processing of the driving support method according to the present embodiment is implemented.

The memory 403 is a volatile storage device such as a RAM (Random Access Memory), and is a storage area for temporarily holding information when the control unit 402 operates. The IF unit 404 is an interface for input / output to / from the outside of the notification unit 43. For example, the IF unit 404 outputs the input data from the outside to the control unit 402, and outputs the data received from the control unit 402 to the outside.

The control unit 402 is a processor, that is, a control device that controls each configuration of the notification unit 43. The control unit 402 reads the operation support program 4012 from the storage device 401 into the memory 403 and executes the operation support program 4012. Further, the control unit 402 appropriately reads the determination model 4011 from the storage device 401 into the memory 403 and executes it. As a result, the control unit 402 realizes the acquisition unit 431, the primary determination unit 432, the collection unit 433, the secondary determination unit 434, the notification information generation unit 435, the mail function unit 436, and the telephone function unit 437.

FIG. 8 is a sequence diagram showing the flow of the driving support method according to the third embodiment. First, it is assumed that the front-rear camera 441 continuously captures peripheral images including the other vehicle 5 while the own vehicle 4 is traveling. At this time, the acquisition unit 431 acquires a peripheral image from the camera ECU 442 (S301). Next, the primary determination unit 432 analyzes the peripheral image (S302). Then, the primary determination unit 432 makes a primary determination of the fanning operation (S303).

When a candidate vehicle is selected in the primary determination result of the road rage (YES in step S303), steps S304 to S306 are executed. That is, the collection unit 433 collects position-related information (S304). In addition, the collecting unit 433 acquires and analyzes a detailed image of the candidate vehicle (S305). In addition, the collecting unit 433 measures information related to the inter-vehicle distance (S306).

On the other hand, if the candidate vehicle is not selected in the primary determination result of the road rage (NO in step S303), the process returns to step S301 and the process is continued.

After steps S304 to S306, the secondary determination unit 434 makes a secondary determination of the driving operation (S307). For example, the secondary determination unit 434 inputs detailed information into the determination model 4301 and outputs a determination result.

When it is determined in the secondary determination result of the fanning operation that the candidate vehicle is driving the fanning (YES in step S307), the notification information generation unit 435 generates the notification information (S308), and the mail function unit 436 or The telephone function unit 437 transmits the notification information to the communication device 31 via the communication device 46 and the communication network N1 (S309). If NO is determined in step S307, the process returns to step S301 and the process is continued.

The notification unit 43 determines whether or not the manual notification button 48 is pressed by the driver or the like at an arbitrary timing. For example, when the candidate vehicle is not selected in the primary determination result of the driving (NO in step S303), and when it is not determined in the secondary determination result that the candidate vehicle is driving in the driving (NO in step S307). However, it is not limited to these. Then, when it is determined that the manual notification button 48 is pressed, the vehicle closest to the other vehicles in the peripheral image is specified as a candidate vehicle for road rage. In that case, steps S309 and S310 are executed. In particular, in step S309, it is desirable that the notification information generation unit 435 further includes the fact that the notification is "a notification based on the subjective judgment of the driver, not the system". In this way, for example, even if the primary judgment does not meet the uniform driving judgment criteria, if the driver or passenger of the own vehicle 4 feels that the driving is driving, the manual notification button 48 is pressed. You can be notified by pressing. As a result, the driver and the like can easily and quickly give the notification.

As described above, in the present embodiment, since various detailed information is collected and the secondary judgment is comprehensively performed, it is possible to exclude cases where the uniform primary judgment standard alone is not appropriate, and the driving operation can be performed. Judgment accuracy can be improved. Further, when the primary determination is not satisfied, the collection process of the collection unit 433 is not executed, so that the processing load of the notification unit 43 can be reduced and unnecessary communication and use of the storage area can be suppressed. Furthermore, the degree of freedom of notification is high by using a plurality of notification methods.

<Embodiment 4>
The fourth embodiment is a specific embodiment of the second embodiment described above. Further, the present embodiment 4 may be a modification of the above-mentioned embodiment 3.

FIG. 9 is a block diagram showing a configuration of the driver assistance system 4000 according to the fourth embodiment. The driver assistance system 4000 includes in-vehicle devices 1b, 1c, ... 1n, and a server 2a, each of which is connected via a network N. In the following description, the same components as those of the above-described embodiments will be designated by the same reference numerals, and the description thereof will be omitted as appropriate. The notification unit 15 may be provided outside the vehicle (for example, the server 2a or the like).

In the vehicle-mounted device 1b, the transmission unit 16 is replaced with the transmission unit 16b in the vehicle-mounted device 1a of FIG. The transmission unit 16b transmits the collected detailed information to the server 2a as learning data of the determination model 25. In particular, when the determination result indicates that the candidate vehicle is driving in a fan, the transmission unit 16b may transmit the collected detailed information to the server 2a as learning data of the determination model 25. The in-vehicle devices 1c to 1n have the same configuration as the in-vehicle device 1b, and are mounted on different vehicles.

The server 2a is the server 2 of FIG. 3 with the learning unit 24 and the determination model 25 added. The determination model 25 corresponds to the determination model 4301 in the above-described third embodiment, and determines whether or not the candidate vehicle is driving in a hurry based on detailed information. The learning unit 24 learns the determination model 25 using the detailed information received in the past as learning data. For example, the learning unit 24 performs machine learning using the learning data and updates the parameters of the determination model 25. Therefore, the determination unit 22 inputs the received detailed information to the learned determination model 25, and uses the output of the determination model 25 as the determination result.

FIG. 10 is a sequence diagram showing a flow of learning data collection and learning processing of the determination model according to the fourth embodiment and subsequent determination processing. For example, it is assumed that the vehicle-mounted device 1c collects detailed information about the candidate vehicle in step S13. Then, the transmission unit 16b of the vehicle-mounted device 1c transmits the collected detailed information to the server 2a via the network N (S41).

Further, it is assumed that the in-vehicle device 1n collects detailed information about the candidate vehicle in step S13, then it is determined that the candidate vehicle is driving in a hurry, and then the notification is given in step S15. Then, the transmission unit 16b of the vehicle-mounted device 1n transmits the collected detailed information to the server 2a via the network N (S42).

After steps S41 and S42, the server 2a learns the determination model 25 using the detailed information received by these as learning data (S43). For example, the detailed information received in step S42 is labeled with a label indicating that the driving is being performed based on the secondary determination result, and the detailed information in step S41 is labeled with a different label for learning. Is also good.

After that, the in-vehicle device 1b performs S13 from steps S11 in the same manner as in FIG. 4, and the transmission unit 16b transmits the detailed information collected by the collection unit 13 to the server 2a via the network N (S21).

Subsequently, the receiving unit 21 of the server 2a receives detailed information from the transmitting unit 16b via the network N. Then, the determination unit 22 determines whether or not the candidate vehicle is driving in a fanning manner based on the detailed information received from the in-vehicle device 1b (S22). At this time, the determination unit 22 uses the learned determination model 25. After that, the notification unit 23 returns the determination result to the in-vehicle device 1b via the network N (S23). As a result, the in-vehicle device 1b can obtain a highly accurate determination result by the learned determination model, and can perform appropriate notification (S15).
As described above, the in-vehicle devices 1a to 1n do not necessarily have to be provided with the notification unit 15. In that case, for example, the notification unit 23 of the server 2a may execute step S23 instead of step S23. Alternatively, in addition to the in-vehicle device 1a and the server 2, there may be a notification device that notifies the police or the like. In that case, the notification unit 23 of the server 2a may set the transmission destination of step S23 as the notification device.

Since the server 2a can collect detailed information from a plurality of in-vehicle devices 1b to 1n, these can be held as history information related to the driving operation. Further, the history information may be used as a blacklist for driving.
