(Functional configuration of information distribution device)

With reference to FIG. 1, the functional configuration of the information distribution apparatus that works on the present embodiment will be described. FIG. 1 is a block diagram showing an example of a functional configuration of an information distribution apparatus that is effective in the present embodiment.

In FIG. 1, the information distribution apparatus 100 includes a receiving unit 101, a specifying unit 102, a generating unit 103, a distributing unit 104, and a force.

[0022] The receiving unit 101 receives, from at least one or more moving bodies, traveling state information relating to the traveling state of the moving body when the moving body exhibits dangerous behavior that causes dangerous behavior. For example, the dangerous behavior may be detected based on the output of various sensors mounted on the moving body, such as the operation and operation of the moving body. The various sensors may be, for example, vibration sensors, G sensors, contact sensors for moving bodies, and sensors that can output information related to operations such as handle operation, direction instruction signal input operation, accelerator pedal operation, and brake pedal operation.

[0023] More specifically, for example, the dangerous behavior is when the output value of various sensors such as a vibration sensor and a G sensor is a value that exceeds a predetermined value, or approximates to a predetermined pattern indicating an abnormality, A case where the contact sensor is activated may be determined as a cause of dangerous behavior. Dangerous behavior can be determined by, for example, operating a moving object when there is an operation that makes a sudden steering more than a predetermined angle, a steering operation that does not require a direction indication, or unnecessary information such as acceleration or deceleration. May be determined as an operation that causes dangerous behavior.

[0024] The traveling state information includes, for example, the moving path of the moving body, the moving speed, the video-sound around the moving body, the object of the dangerous behavior, the output results of various sensors when the dangerous behavior is shown, and the like. It is. In addition, the driving state information may include, for example, date and time information when a dangerous behavior is indicated, point information, and storage date and time information related to the start and end date and time of saving video data.

[0025] Using the running state information received by the receiving unit 101, the specifying unit 102 specifies a dangerous behavior frequent occurrence point where the dangerous behavior occurs frequently. Specifically, for example, the dangerous behavior frequent occurrence point may be a point where a large number of dangerous behaviors are shown by a plurality of moving bodies.

[0026] Further, the identifying unit 102 may identify the dangerous behavior occurrence point where the dangerous behavior has occurred from the running state information received by the receiving means.

The generation unit 103 generates alert information for the dangerous behavior frequent occurrence point specified by the specifying unit 102. Specifically, for example, the alerting information may be information including distribution information of dangerous behavior frequent occurrence points on a map using traveling state information.

[0028] Further, the generation unit 103 may generate alert information for the dangerous behavior occurrence point specified by the specification unit 102.

[0029] The distribution unit 104 distributes the alert information generated by the generation unit 103 to a moving body that passes through the dangerous behavior multiple points. Specifically, for example, for the distribution of the alert information, the distribution information generated by the generation unit 103 may be distributed.

[0030] Further, the distribution unit 104 may distribute the alert information generated by the generation unit 103 to a moving body located within a predetermined range from the dangerous behavior occurrence point.

[0031] (Functional configuration of information processing apparatus)

Next, the functional configuration of the information processing apparatus that is useful in the present embodiment will be described with reference to FIG. FIG. 2 is a block diagram showing an example of a functional configuration of the information processing apparatus that is effective in the present embodiment. In FIG. 2, an information processing apparatus 200 that overwrites and records traveling state information relating to a traveling state of a moving body that is continuously input includes a detection unit 201, a determination unit 202, an output unit 203, and a force configuration. Has been.

[0033] The detection unit 201 detects the behavior of the moving object. The behavior of the moving body may be detected based on, for example, the output of various sensors mounted on the moving body, such as the operation and operation of the moving body. The various sensors are, for example, vibration sensors, G sensors, touch sensors for moving objects, and sensors that can output information related to operations such as steering wheel operation, direction instruction signal input operation, accelerator pedal operation, and brake pedal operation. Good.

The determination unit 202 determines whether or not the detection result force detected by the detection unit 201 causes a dangerous behavior of the moving body. Specifically, for example, the determination unit 202 determines whether the output value of various sensors such as a vibration sensor and a G sensor in the detection unit 201 is a value that exceeds a specified value, approximates to a predetermined pattern indicating abnormality, or a contact sensor. It may be judged as the cause of dangerous behavior when the is activated.

[0035] Further, for example, the determination unit 202 may determine that a dangerous behavior is caused when a dangerous operation is performed based on information on the operation of the moving object. More specifically, for example, when there is an operation of making a sudden handle more than a predetermined angle, a handle operation without a direction instruction, or output of information such as unnecessary acceleration and deceleration, the operation of the moving body is performed. The configuration may be determined as an operation that causes a dangerous behavior.

[0036] When the determination unit 202 determines that the detection result of the detection unit 201 causes a dangerous behavior, the output unit 203 outputs traveling state information to an external device (not shown). The running state information is information including, for example, the moving route of the moving body, the moving speed, the video “sound” around the moving body, the object of the dangerous behavior, the detection result in which the behavior is detected, and the like. Further, the running state information may include, for example, date and time information when a dangerous behavior is indicated, point information, and storage date and time information related to the start and end date and time of saving video data. In addition, output to external equipment may be performed by wireless or wired communication, for example.

[0037] (Contents of processing of information distribution apparatus)

Next, the contents of the processing of the information distribution apparatus 100 will be described with reference to FIG. And explain. FIG. 3 is a flowchart showing the contents of processing of the information distribution apparatus according to the present embodiment. In the flowchart of FIG. 3, first, the receiving unit 101 determines whether or not the traveling state information of the moving body has been received (step S301). The traveling state information may be received from a plurality of moving bodies, for example.

[0038] In step S301, if the driving state information is received and received (step S301: Yes), the identifying unit 102 uses the driving state information received in step S301 to A dangerous behavior frequent occurrence point where behavior occurs frequently is specified (step S302). In the flowchart of FIG. 3, the location where the dangerous behavior occurs frequently is specified in step S302. However, the location where the dangerous behavior occurred may be specified instead of the location where the dangerous behavior occurs frequently.

[0039] Next, the alerting information is generated by the generation unit 103 for the dangerous behavior multiple occurrence points identified in step S302 (step S303). The alert information is, for example, information for calling a user of a moving body passing through or around a dangerous behavior frequent occurrence point at the dangerous behavior frequent occurrence point. In addition, for example, when the dangerous behavior occurrence point is specified instead of the dangerous behavior frequent occurrence point in step S302, the alert information may be information regarding the dangerous behavior occurrence point.

[0040] Then, the alerting information generated in step S303 is distributed by the distribution unit 104 (step S304), and the series of processing ends. For example, the alert information may be distributed to a mobile body that passes through a point where the dangerous behavior occurs frequently, or may be distributed to a mobile body located within a predetermined range from the point where the dangerous behavior occurs.

[0041] (Contents of processing of information processing apparatus)

Next, the contents of the processing of the information processing apparatus 200 that is useful for the present embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing the contents of the processing of the information processing apparatus according to this embodiment. In the flowchart of FIG. 4, first, the detection unit 201 determines whether or not the behavior of the moving object has been detected (step S401).

[0042] In step S401, waiting for detection of the behavior of the moving object, and if detected (step S401: Yes), the determination unit 202 makes a determination on the behavior of the moving object detected in step S401. Perform (step S402). Judgment regarding behavior is, for example, The detection result force S detected in step S401 may be used to determine whether or not it causes a dangerous behavior of the moving object.

[0043] Based on the determination result determined in step S402, output state information is output by the output unit 203 (step S403), and the series of processing ends. For example, when it is determined that the detection result in step S401 causes a dangerous behavior, the driving state information may be output to an external device (not shown).

[0044] As described above, according to the information distribution apparatus in the present embodiment, the alert information can be distributed to a moving body that passes the dangerous behavior occurrence point. However, it is possible to improve the safety related to the movement of the moving body.

[0045] In addition, according to the information distribution apparatus in the present embodiment, the alert information can be distributed to a mobile body located within a predetermined range from the dangerous behavior occurrence point, so that the mobile body determines the dangerous behavior occurrence point. By grasping, it is possible to avoid danger.

[0046] Also, according to the information processing apparatus of the present embodiment, when dangerous behavior is detected, the driving state information is output to the external device, so that the driving state information can be analyzed by the external device. it can. In particular, if the driving state information of multiple moving bodies is analyzed by an external device, it is possible to prevent accidents of the moving body while widespread use of the driving state information by analyzing general dangerous behavior. .

Example

[0047] Examples of the present invention will be described below. In this embodiment, for example, the information distribution device of the present invention is implemented by a server installed in an information collection center that receives various information from a moving body such as a vehicle (including a four-wheeled vehicle and a two-wheeled vehicle). An example in which the information processing apparatus of the present invention is implemented by a navigation apparatus having a drive recorder function mounted on a moving body will be described.

[0048] (Server hardware configuration)

First, the hardware configuration of a server that is useful in this embodiment will be described with reference to FIG. FIG. 5 is a block diagram illustrating an example of a hardware configuration of a server that is useful in the present embodiment.

[0049] In FIG. 5, the server 500 collects various information transmitted from the vehicle. Installed in the center, CPU501, ROM502, RAM503, magnetic disk drive 504, magnetic disk 505, optical disk drive 506, optical disk 507, audio I / F (interface) 508, speaker 509 , An input device 510, a video I / F 511, a display 512, and a communication I / F 513. In addition, each component B501 to 513 is connected by a bus 520.

The CPU 501 governs overall control of the server 500. The ROM 502 stores various programs such as a boot program, a communication program, a voice generation program, an information display program, a database creation program, and a data analysis program. The RAM 503 is used as a work area for the CPU 501.

[0051] The audio generation program may generate tone and audio information corresponding to the pattern and output the information to the audio I / F 508 via the CPU 501. Further, the information display program determines the display format of information to be displayed on the display 512 by the video 1 / F511, and displays the information on the display 512 according to the determined display format.

[0052] Further, when the CPU 501 receives a new trigger list from a navigation device (see Fig. 6) mounted on the vehicle or the like via a communication I / F 513 described later, the CPU 501 reads a magnetic disk 505 or an optical disk described later. Update the trigger list recorded in 507. Then, based on the updated trigger list, the CPU 501 generates an information acquisition request for requesting various information to the navigation device, and transmits the information acquisition request to the navigation device via the communication I / F 513.

[0053] The trigger list includes, for example, the output value of the trigger sensor, the trigger type, and the position at which the trigger is detected when the trigger is detected by the navigation device that may be generated by the navigation device. It can also be a list that includes information, detection date and time, storage start date and time and end date and time of the drive recorder image that is saved by detecting the vehicle trigger. The trigger type is triggered by G sensor detection, for example, whether it is triggered by a change in driving behavior such as sudden braking, sudden steering, etc. This indicates the type that causes this.

[0054] Various information requested by the information acquisition request is, for example, based on vehicle trigger detection. The image for the drive recorder stored in this way or information on the running state of the vehicle at the time of trigger detection may be used. Examples of the information related to the driving state of the vehicle include information related to the driving environment, such as information related to the weather, information related to the road surface condition, and power.

In addition, the CPU 501 generates accident prevention point information with reference to the trigger list and various information received from the navigation device, and also generates a browsing image corresponding to the accident prevention point.

[0056] The details will be described with reference to FIGS. 7 and 8. As for the accident prevention point information, for example, a vehicle equipped with a navigation device that detects a trigger from a list of triggers or various information encounters an accident or a near-miss. Information indicating the point where a large number of triggers were detected. In other words, it is information indicating a point where a plurality of vehicles have detected the trigger, and may be information regarding a point where accidents or near-misses occur frequently.

[0057] The accident prevention point information may be, for example, information about a point where a trigger is detected in real time, instead of a point where many triggers are detected. Further, the accident prevention point information may be, for example, information for voice output.

[0058] Further, as the browsing image, for example, it is possible to select an image that remarkably indicates the cause of the trigger detection, such as a drive recorder image at the point where the trigger is detected. In addition, the browsing image may be an image incorporating information on a corresponding trigger that may be either a moving image or a still image.

[0059] Accident prevention point information and browsing images are mounted on vehicles via communication I / F 513, which may be recorded on magnetic disk 505 or optical disk 507 in association with a trigger list, for example. When a request is received from the navigation device, information corresponding to the request may be transmitted to the navigation device.

[0060] Further, the accident prevention point information and the browsing image may be information that is displayed together with trigger information at a point where the trigger is detected in the navigation device. The details will be explained with reference to Fig. 7 and Fig. 8, but accident prevention point information can be generated by referring to the trigger list at the time of trigger detection. In addition, it may be configured to incorporate trigger information including a history and a situation.

[0061] Specifically, for example, accident prevention point information includes a vehicle equipped with a navigation device. This information is displayed together with the map information around the vehicle equipped with the navigation device when the current location of the vehicle approaches the location where the trigger was detected in the past. For this accident prevention point information, for example, the date and time when the trigger is detected may be written together, or for information going back in the past, the display point may be made smaller or the color may be made lighter.

More specifically, for example, the accident prevention point information may be information that displays information related to past trigger detection within a predetermined period from the latest trigger detection on a map on which the vehicle is traveling. In addition, accident prevention point information may be information that displays the traveling direction of the vehicle, the traveling trajectory, and the behavior of surrounding features when the trigger is detected from the traveling history of the vehicle when the trigger is detected. Alternatively, the information on the running state such as the vehicle speed may be displayed together.

[0063] Further, the accident prevention point information may be displayed in a reduced quantity according to the scale of the map information displayed on the display of the navigation device, for example. Specifically, for example, old trigger information may not be displayed, or trigger information having a smaller output value of the sensor that has detected the trigger may not be displayed. That is, it is good also as information which selectively displays the information where the more dangerous trigger was detected.

The magnetic disk drive 504 controls reading / writing of data with respect to the magnetic disk 505 according to the control of the CPU 501. The magnetic disk 505 records data written under the control of the magnetic disk drive 504. For example, HD (node disk) or FD (flexible disk) can be used as the magnetic disk 505.

The optical disk drive 506 controls reading / writing of data with respect to the optical disk 507 according to the control of the CPU 501. The optical disc 507 is a detachable recording medium from which data is read according to the control of the optical disc drive 506. The optical disk 507 can use a writable recording medium. In addition, the removable recording medium may be a power MO of the optical disc 507, a memory card, or the like.

Examples of information recorded on the magnetic disk 505 and the optical disk 507 include the above-described trigger list, accident prevention point information, and browsing images. In addition, map information used to generate other accident prevention point information may be recorded.

The audio I / F 508 is connected to an audio output speaker 509. Sound from speaker 509 Voice is output. Examples of the input device 510 include a remote controller having a plurality of keys for inputting characters, numerical values, various instructions, etc., a keyboard, a mouse, and a touch panel.

In addition, video IZF 511 is connected to display 512. Specifically, the video IZF511 is output from, for example, a graphic controller that controls the entire display 512, a buffer memory such as VRAM (Video RAM) that temporarily records image information that can be displayed immediately, and a graphic controller. It is configured by a control IC that controls display of the display 512 based on image data to be displayed.

[0069] The display 512 may be configured to display icons, cursors, menus, windows, or various data such as characters and images. The display 512 can also display various data such as characters and images by controlling the lighting location and timing of a plurality of light emitting diodes like an electric bulletin board. Also, for example, adopting CRT, TFT liquid crystal display, plasma display, etc.

[0070] The communication I / F 513 is connected to the network via radio, and functions as an interface between the Sanoku 500 and the CPU 501. The communication I / F 513 is further connected to a communication network such as the Internet via wireless, and also functions as an interface between the communication network and the CPU 501. Communication networks include LAN, WAN, public line network and mobile phone network. Specifically, the communication I / F 513 is configured by, for example, an FM tuner, a wireless device, etc., and acquires information on road traffic information such as traffic jams and traffic regulations distributed from the outside and information on displayed signs. Further, the communication I / F 513 may be configured to receive various information such as a trigger list, an accident prevention point information request, and a drive recorder image from the navigation device.

[0080] Further, the display program may determine the display format of the accident prevention point information received from the server 500 described above and display the image on the display 613 according to the determined display format. ,. Details will be described with reference to FIG. 7 and FIG. 8, but accident prevention site information and browsing images may be displayed together with map information, for example.

Further, the CPU 601 may generate a trigger list when a trigger described later is detected and transmit it to the server 500 via the communication I / F 614. Specifically, for example, the trigger list is a drive recorder that is stored when the trigger is detected, the output value of the sensor that triggered it, the location information that detected the trigger, the detection date and time, and the vehicle trigger detection. A list including the storage start date and time and the storage end date and time of the image for use may be used.

[0082] Further, the CPU 601 may be configured to switch the recording destination of the traveling state of the vehicle that has always been overwritten when a trigger is detected by various sensors 616 described later. The driving state recording destination may have, for example, an overwriting recording area for always overwriting the driving state and a storage recording area for saving the driving state when a trigger is detected. A recording medium for storage and a recording medium for storage may be provided. Further, there may be a plurality of overwriting recording areas and overwriting recording media.

The magnetic disk drive 604 controls reading / writing of data with respect to the magnetic disk 605 according to the control of the CPU 601. The magnetic disk 605 records data written under the control of the magnetic disk drive 604. As the magnetic disk 605, for example, HD (node disk) or FD (flexible disk) can be used.

The optical disk drive 606 controls reading / writing of data with respect to the optical disk 607 according to the control of the CPU 601. The optical disc 607 is a detachable recording medium from which data is read according to the control of the optical disc drive 606. The optical disk 607 can also use a writable recording medium. This removable In addition to the optical disc 607, the recording medium may be an MO, a memory card, or the like.

[0085] As an example of information recorded on the magnetic disk 605 and the optical disk 607, internal and external audio and video obtained by a microphone 609 and a camera 617, which will be described later, and the current position of the vehicle detected by a GPS unit 615, which will be described later Information, and output values from various sensors 616 described later. Also, the trigger information can be accumulated and saved based on the triggers detected from the output of various sensors 616. These pieces of information are recorded by the drive recorder function of the navigation device 600 and are used as verification materials when a traffic accident occurs.

Other examples of information recorded on the magnetic disk 605 and the optical disk 607 include map information used for route search / route guidance. The map information includes background data that represents features (features) such as buildings, rivers, and the ground surface, and road shape data that represents the shape of the road. The original drawing. When the navigation device 600 is guiding a route, the map information and the current location of the vehicle acquired by the GPS unit 615 described later are displayed in an overlapping manner.

In this embodiment, the map information is recorded on the magnetic disk 605 and the optical disk 607. However, the present invention is not limited to this. The map information may be provided outside the navigation device 600, not the information recorded only in the one integrated with the navigation device 600 hardware. In that case, the navigation device 600 acquires map information via the network through the communication I / F 614, for example. The acquired map information is recorded in RAM 603 or the like.

The audio I / F 608 is connected to a microphone 609 for audio input and a speaker 610 for audio output. Audio received by the microphone 609 is AZD converted in the audio I / F 608. In addition, sound is output from the speaker 610. Note that the voice input from the microphone 609 can be recorded on the magnetic disk 605 or the optical disk 607 as voice data.

[0089] Examples of the input device 611 include a remote controller, a keyboard, a mouse, and a touch panel, each having a plurality of keys for inputting characters, numerical values, various instructions, and the like.

In addition, video IZF 612 is connected to display 613 and camera 617. Specifically, the video I / F 612 is a graphic coordinator that controls the entire display 613, for example. Controller, a buffer memory such as VRAM (Video RAM) that temporarily records image information that can be displayed immediately, and a control IC that controls the display of the display 613 based on image data output from the graphic controller. The

[0091] The display 613 displays icons, cursors, menus, windows, or various data such as characters and images. As this display 613, for example, a CRT, TFT liquid crystal display, plasma display or the like can be adopted. A plurality of displays 613 may be provided in the vehicle, for example, for the driver and for a passenger seated in the rear seat.

[0092] The camera 617 captures an image inside or outside the vehicle. The image can be either a still image or a moving image. For example, a camera 617 captures the behavior of a passenger inside the vehicle, and the captured image is recorded on a recording medium such as a magnetic disk 605 or an optical disk 607 via a video I / F612. Output to. In addition, the camera 617 captures the situation outside the vehicle, and the captured image is output to a recording medium such as the magnetic disk 605 and the optical disk 607 via the video I / F 612. The video output to the recording medium is overwritten and recorded as a drive recorder image.

In addition, the communication I / F 614 is connected to a network via radio and functions as an interface between the navigation device 600 and the CPU 601. The communication I / F 614 is further connected to a communication network such as the Internet via radio, and functions as an interface between the communication network and the CPU 601.

[0094] Communication networks include LANs, WANs, public line networks and mobile phone networks. Specifically, the communication I / F 614 includes, for example, an FM tuner, a VICS (Vehicle Information and Communication System) / beacon receiver, a wireless navigation device, and other navigation devices, and is congested delivered from the VICS center. And road traffic information such as traffic regulations. VICS is a registered trademark.

[0095] Further, the GPS unit 615 uses a received wave from a GPS satellite and output values from various sensors 616 (for example, an angular velocity sensor, an acceleration sensor, and a tire rotation number) to be described later, Information indicating the location (the current location of the navigation device 600) is calculated. The information indicating the current location specifies one point on the map information, for example, latitude / longitude and altitude. Information.

[0096] Various sensors 616 are a vehicle speed sensor, an acceleration sensor, a G sensor, an angular velocity sensor, and the like, and their output values are used for calculating the current position by the GPS unit 615 and measuring the amount of change in speed and direction. It is done. Specifically, for example, the various sensors 616 output an odometer, a speed change amount, an azimuth change amount, and the like. This output value can be used to analyze dynamics such as sudden braking, sudden braking, and dollars.

[0097] Various sensors 616 also include sensors that detect each operation of the vehicle by the driver. The detection of each operation of the vehicle may be configured to detect, for example, steering wheel operation, turn signal input, accelerator pedal depression, or brake pedal depression. Also, the output value of various sensors 616 can be recorded as data with the drive recorder function.

[0098] The various sensors 616 may have a configuration in which a trigger for storing the drive recorder image is set in advance and the drive recorder image is stored when the trigger is detected. The trigger is, for example, a trigger for storing the drive recorder image, and may be configured such that the output from the various sensors 616 is equal to or higher than a predetermined threshold or output that approximates a predetermined pattern.

[0099] More specifically, for example, triggers in various sensors 616 may be set when vibrations exceeding a specified level or a predetermined vibration pattern are detected by the vibration sensor. The predetermined vibration pattern may be a vibration pattern that shows an abnormality such as a sudden rise. The trigger 1 may be set when, for example, the G sensor detects a G exceeding a specified value or a pattern of how to apply a predetermined G force. The predetermined G force may be any pattern that shows an abnormality such as a sudden rise. Alternatively, the vehicle contact sensor may be used to trigger the presence or absence of contact with the other, the operation of an airbag, or the stop of the vehicle. Furthermore, as long as there is one or more of the above-mentioned triggers, a combination of multiple triggers may be used.

[0100] Of the functional configuration of the information processing apparatus 200 that is relevant to the embodiment, the detection unit 201 is based on various sensors 616, the determination unit 202 is based on the CPU 601, and the output unit 203 is based on the speaker 610 and the display 613. Each implements its function.

[0101] Here, with reference to FIG. 7, the display of the accident prevention point information will be explained, focusing on this example. To do. FIG. 7 is an explanatory diagram showing a display using a bar graph for accident prevention point information that is useful in the present embodiment. The details described with reference to FIGS. 9 and 10 In this embodiment, the accident prevention point information is information generated by the server 500 on the basis of the trigger list, and in response to a request from the navigation device 600. The server 500 transmits to the navigation device 600 and displays it on the navigation device 600.

[0102] In FIG. 7, on a map 700, a route 701, a trigger detection number 702 at a trigger detection point on the route 701, a balloon 703 regarding the trigger cause, and a vehicle position 710 are shown.

[0103] The route 701 exists on the map 700 within a predetermined range from the vehicle position 710, for example. That is, on the map 700, the number of trigger detections 702 at the trigger detection points on the route 701 in a predetermined range from the own vehicle position 710 is displayed as a bar graph.

[0104] For example, the number of trigger detections 702 may be displayed as a long bar graph as the number of trigger detections increases. In addition, the trigger detection number 702 may be translucent so that the path 701 can be seen through.

[0105] The trigger detection number 702 may be displayed in a different color depending on the type of sensor that has detected the trigger, or may be configured to be displayed for each type of sensor. Furthermore, additional information such as the average output value of the trigger sensor and the date and time of detection may be displayed in accordance with the trigger detection count 702. The trigger detection number 702 may be displayed only on the route to the destination when the route to the destination in the vehicle is set.

[0106] Furthermore, when the user selects the displayed trigger detection number 702, an image browsing request such as a typical image for a drive recorder corresponding to the trigger detection number 702 may be made. The image browsing request may be transmitted to the server 500 via the communication I / F 614 and receive a browsing image from the server 500, for example.

[0107] Specifically, for example, when a user requests browsing of a browsing image related to detection of a trigger according to the display on the display 613, the corresponding browsing is performed by requesting the browsing image from the server 500. An image for use may be displayed. In this case, the browsing image to be displayed is, for example, an image of a certain section before and after the trigger is detected, It may be a still image at an arbitrary point in a certain section.

[0108] In addition, the browsing image in response to this request may be displayed together with, for example, the map information. The user may check the traveling position of the vehicle and the browsing image together. It is possible to prevent accidents more reliably.

[0109] For example, in addition to the image for the drive recorder and the related image, the browsing image can be browsed with additional information such as the output value of the sensor when the trigger is detected and the running state of the vehicle. The configuration may be instructed. In this way, the user can specifically confirm the dangerous behavior of the vehicle.

[0110] In addition, the display of accident prevention point information such as the number of trigger detection points 702 of the trigger detection points on these maps 700 may be configured to be displayed as necessary, for example. In other words, when it is necessary to notify the user that the trigger has been detected in the past, the server 500 may be requested to request and display the accident prevention point information.

[0111] Specifically, for example, the accident prevention point information is displayed when the host vehicle position 710 is within a predetermined range from the past trigger detection point, and the server 500 is notified of the accident prevention point information. A configuration may be adopted in which a request is made and displayed.

[0112] For example, when the server 500 receives a new trigger list from the navigation device 600, the balloon 703 obtains the cause of the trigger by using information indicating the trigger and the detected cause. The structure added to information may be sufficient. The cause of the trigger may be extracted from, for example, traffic information or VICS information at the point where the trigger is detected, and the user takes appropriate measures by notifying the user of the cause of the trigger detection. be able to.

[0113] Although description is omitted in FIG. 7, when the vehicle approaches the trigger detection point, the user may be notified by voice output. Specifically, for notification by voice output, for example, when the server 500 grasps the trigger detection corresponding to the accident, the trigger generation time and generation position are transmitted to the navigation device 600 of the vehicle around the position. . The navigation device 600 compares the trigger occurrence time and position with the current position, traveling direction, current time, and route of the vehicle, and says `` There is a possibility that an accident occurred 10 minutes before the intersection of 300 m ahead. Please be careful when driving. " Audio output may be performed.

[0114] Also, if the server 500 can confirm the accident, for example, the voice output saying "An accident occurred 10 minutes ago at the intersection 300m ahead. Also good.

[0115] In addition, the navigation device 600 compares the accident prevention point information received from the server 500 with the current position, traveling direction, and route of the host vehicle, according to the number of detected triggers 702 in the accident prevention point information. “The intersection 300m ahead is a frequent accident site. Please be careful about driving.” Or “The intersection 300m away is a place where accidents are relatively likely to occur. Be careful when driving.” Also good.

[0116] If the navigation device 600 receives accident prevention point information including triggers such as sudden braking, sudden steering, sudden start, etc. “Brake, sudden handle, sudden start, etc. occur frequently. Please be careful about driving.”

[0117] In addition, the navigation device 600 receives accident prevention point information in which triggers such as sudden braking, sudden steering, sudden start, etc. suddenly increased (changed in real time), which is not equivalent to an accident. However, it is possible to make a voice output saying “There are many sudden braking, sudden steering, sudden start, etc. on the right curve of 300m ahead. Further, in this case, when the cause of sudden start, etc. can be identified by sudden braking, sudden steering, or server 500, navigation device 600 receives accident prevention point information including the cause, You may be able to make a voice output saying “Be careful when driving.

[0118] Next, with reference to FIG. 8, a display different from that in FIG. 7 in the accident prevention point information that is useful in the present embodiment will be described. FIG. 8 is an explanatory diagram showing a display in which the trigger detection point is colored with respect to the accident prevention point information that is relevant to the present embodiment.

[0119] In FIG. 8, on the map 800, a route 801 and trigger detection points 802 and 803 are shown.

[0120] The route 801 exists on a map within a predetermined range from the current point of the vehicle, for example.

That is, on the map 800, a route 801 in a predetermined range from the current position of the vehicle is displayed. Trigger detection points 802, 803 are colored.

[0121] For example, the trigger detection points 802 and 803 may be configured to be colored with a darker color as the number of trigger detections increases. In the description of FIG. This is a configuration in which the trigger is detected more frequently.

[0122] In the description of FIG. 8, the trigger detection points 802 and 803 may be configured to perform color coding of three or more types of forces indicated by two types.

[0123] In addition, the trigger detection points 802 and 803 may be darkened in order from the most important trigger instead of the number of times the trigger is detected. Specifically, for example, trigger detection point 802, 8

03 is good for darkening the color from the sensor with the highest output value when a trigger is detected.

[0124] More specifically, for example, when the trigger detection points 802 and 803 detect a trigger by a plurality of sensors, the respective output values are scored, and even if the color is darkened from a higher score, Yo! In this way, it is possible to accurately grasp the trigger detection points 802 and 803 that are more dangerous.

[0125] (Contents of processing of navigation device 600)

Here, the contents of processing of the navigation device 600 according to the present embodiment will be described with reference to FIG. FIG. 9 is a flowchart showing the contents of the processing of the navigation device that is useful in this embodiment. In the flowchart of FIG. 9, the navigation device 600 first determines whether or not the vehicle has started running (step S901). The determination regarding the running of the vehicle may be made with reference to the outputs of the various sensors 616, for example.

[0126] In step S901, when the vehicle starts running after waiting for the vehicle to start running (step S901: Yes), the CPU 601 controls the magnetic disk drive 604 and the optical disk drive 606 to control the magnetic disk 605 and the like. The drive recorder image taken by the camera 617 is overwritten and recorded on a recording medium such as the optical disc 607 (step S902). Overwrite recording is, for example, recording a moving image over a certain period of time by overwriting sequentially so as not to exceed the recording capacity of the recording medium, and has a recording medium for overwriting recording and a recording area for overwriting recording. Record on a recording medium.

[0127] Next, the CPU 601 determines whether or not a trigger is detected (step S903). . The trigger may be, for example, a trigger for saving the drive recorder image by the output of various sensors 616.

[0128] More specifically, for example, the trigger may be set when a vibration sensor detects a vibration exceeding a specified level or a predetermined vibration pattern. The predetermined vibration pattern may be a vibration pattern showing an abnormality such as a sudden rising force ^. For example, the trigger may be set when the G sensor detects a G pattern that exceeds the specified level or a predetermined G force pattern. The prescribed G can be applied to any pattern that shows an abnormality, such as a sudden rising G. Alternatively, it may be configured to trigger on the operation of an air bag, such as the presence or absence of contact with the other, by the contact sensor of the vehicle body.

[0129] Further, the CPU 601 may detect the trigger by detecting the driving operation of the driver that causes dangerous behavior of the vehicle based on the output of the various sensors 616.

[0130] If a trigger is detected in step S903 (step S903: Yes), the CPU 6001 controls the magnetic disk drive 604 and the optical disk drive 606, and the recording medium such as the magnetic disk 605 and the optical disk 607 is used for the drive recorder. The image is saved (step S904) and the trigger list is updated (step S905). The trigger list is not limited to the timing when the drive recorder image is saved. For example, the trigger list is updated even when a trigger that does not require saving the drive recorder image is detected. Motole.

[0131] Then, the CPU 601 performs a step with respect to the server 500 via the communication I / F 614.

The trigger list updated by S905 is transmitted (step S906).

[0132] If a trigger is not detected in step S903 (step S903: No), the process proceeds to step S906 and a pre-recorded trigger list is transmitted to server 500 (step S906). .

Next, the communication IZF 614 determines whether an information acquisition request has been received from the server 500 (step S907). The information acquisition request may be, for example, information in which the server 500 requests an image for a drive recorder, information on the vehicle running state when a trigger is detected, or the like.

[0134] When an information acquisition request is accepted in step S907 (step S907: Yes), The communication I / F 614 transmits information corresponding to the information acquisition request received in step S907 to the server 500 (step S908).

[0135] Then, the current location of the vehicle is acquired by the GPS unit 615 (step S909), and at the same time, the server 500 is requested of the accident prevention location information at the current location via the communication IZF614 (step S910). . The request for accident prevention point information may be, for example, requesting accident prevention point information in a predetermined range from the current point.

[0136] If the information acquisition request is not accepted in step S907 (step S907: No), the process proceeds to step S909, and the current location of the vehicle is acquired by the GPS unit 615 (step S909). ) And requesting accident prevention point information at the current point from server 500 via communication IZF614 (step S910).

[0137] Then, the display 613 displays a map including the accident prevention point information transmitted from the server 500 in accordance with the accident prevention point information requested in step S910 (step S911). Specifically, for example, the map display including accident prevention point information is the accident prevention point information shown in FIGS.

[0138] Then, the input device 611 determines whether or not an image browsing request has been received from the user according to the map display made in step S911 (step S912).

[0139] When an image browsing request is accepted in step S912 (step S912: Yes), the image browsing request accepted in step S912 is transmitted to the server 500 via the communication I / F 614 (step S913). The communication I / F 614 determines whether or not the browsing image is received from the server 500 (step S914).

[0140] If an image browsing request is not accepted in step S912 (step S912: No), the process proceeds to step S916, and the navigation device 600 determines whether or not the vehicle has finished traveling (step S912). S916). For example, you may make judgments about vehicle travel by referring to the output of various sensors 616. More specifically, it may be determined that the traveling of the vehicle has ended when the output of the various sensors 616 stops.

[0141] In step S914, after waiting for receiving the browsing image (step S914: Yes), the display 613 displays the browsing image received in step S914 (step S914: Yes). Step S915). For example, viewing images can be displayed It may be performed together with map information including the current location of the vehicle.

[0142] Then, navigation device 600 determines whether or not the vehicle has finished traveling (step S916).

In step S916, if the vehicle does not finish running (step S916: No), the process returns to step S902 to repeat overwriting recording of the drive recorder image. In step S916, when the vehicle finishes running (step S916: Yes), the series of processing ends.

[0144] In the flowchart of FIG. 9, the force described for the processing by the navigation device 600 having the drive recorder function is described. The accident prevention point information is not updated by another navigation device that does not perform the processing from step S902 to step S908. It is also possible to display images for display and viewing.

[0145] Specifically, for example, other navigation devices can request and display the accident prevention point information at the position of the vehicle by the process of transition of step S908 shown in FIG. That is, even if the own vehicle does not have a drive recorder function, the information of the navigation device 600 having a plurality of drive recorder functions can be used.

[0146] (Processing contents of server 500)

Next, the processing contents of the server 500 according to the present embodiment will be described with reference to FIG. FIG. 10 is a flowchart showing the contents of the processing of the server according to the present embodiment. In the flowchart of FIG. 10, first, it is determined whether or not a new trigger list has been received from the navigation device 600 through the communication I / F 513 (step S1001).

[0147] In step S1001, it waits for the reception of a new trigger list, and if it is received (step S1001: Yes), the CPU 501 updates the trigger list (step S10

02).

Next, the communication I / F 513 transmits an information acquisition request to the navigation device 600 that is the transmission source of the new trigger list in step S1001 (step S10

03). The information acquisition request may be, for example, information on a trigger corresponding to the new trigger list, a drive recorder image, or the like.

[0149] Next, obtain the information sent in step S1003 by communication I / F513. The information transmitted from the navigation device 600 is received in response to the request (step S10 04).

[0150] Then, the CPU 501 generates accident prevention point information using the information received in step S1004 (step S1005). After receiving the new trigger list in step S1001, the power to send the information acquisition request to the navigation device 600 that has sent the trigger list in step S1003. Information acquisition request to generate accident prevention point information to be performed in step S1005 when it is received, and to acquire video information etc. only at points where there are many triggers at the accident prevention point or suspected accident occurrence May be transmitted.

Next, it is determined by communication IZF513 whether a request for accident prevention point information has been received from navigation device 600 (step S1006).

[0152] If a request for accident prevention point information is accepted in step S1006 (step S 1006: Yes), the accident prevention point information corresponding to the request accepted in step S1006 is transmitted by communication I / F513 (step S1006: Yes). Along with S1007), it is determined whether or not an image viewing request has been received from navigation device 600 (step S1008).

[0153] If the request for accident prevention point information is not accepted in step S1006 (step S1006: No), the process proceeds to step S1008, and an image browsing request is accepted from navigation device 600 by communication I / F513. Judgment is made (step S1008)

In step S1008, when an image browsing request is not accepted (step S1008: No), a series of processing ends. If an image browsing request is received in step S1008 (step S1008: Yes), the CPU 501 has a browsing image corresponding to the request in step S1008 on a recording medium such as the magnetic disk 505 or optical disk 507. (Step S1009).

[0155] In step S1009, if there is a browsing image (step S1009: Yes), the browsing image is transmitted to navigation device 600 by communication I / F 513 (step S1010), and a series of processing is performed. finish.

[0156] In step S1009, if there is no image for viewing (step S1009: No), Then, the communication I / F 513 transmits an information acquisition request for the browsing image to the navigation apparatus 600 having the browsing image (step S1011), and receives the corresponding browsing image (step S1012).

[0157] Then, the browsing image received in step S1012 is transmitted to navigation device 600 by communication I / F 513 (step S1010), and the series of processing ends.

[0158] It should be noted that when there is no image for viewing in step S1009 (the explanation is omitted in the flowchart of FIG. 10) (step S1009: No), the communication I / F 513 notifies the navigation device 600 to that effect. The structure to do may be sufficient.

[0159] Further, in the flowchart of FIG. 10, when the new trigger list is received in step S1001, the subsequent processing is performed. However, the accident prevention point in step S1006 is not required even if the new trigger list is not received. When you receive a request for information, you can do the following processing. As a result, accident prevention point information can be transmitted even to the navigation device 600 that does not detect a trigger, and a wide range of users can safely drive.

In the flowcharts of FIGS. 9 and 10, the navigation device 600 acquires the current location of the vehicle and requests the server 500 for accident prevention location information including the current location. This isn't limited to this.

[0161] Specifically, for example, the server 500 is configured to always acquire the current location of the vehicle from a plurality of navigation devices 600 and manage each. Then, the accident prevention point information may be transmitted to the navigation device 600 that approaches the accident prevention point. In this way, the navigation apparatus 600 can acquire accident prevention point information suitable for the current position of the own apparatus without detecting a trigger.

[0162] Server 500 may be configured to broadcast accident prevention point information to a plurality of navigation devices 600 in a broadcast manner without confirming the current location of navigation device 600. In that case, the navigation device 600 compares the received accident prevention point information with the current location and direction of travel of the vehicle equipped with the navigation device 600 to determine whether or not to display the accident prevention point information. Just judge. In this way, the server 500 does not have to perform processing related to the current location of the navigation device 600. The processing load can be reduced.

[0163] As described above, according to the present embodiment, the user can travel while avoiding danger by checking the accident prevention point information and the browsing image. In addition, since information related to trigger detection in a plurality of navigation devices can be used, information can be effectively used.
