FIG. 6 is a first diagram showing the processing flow of the drive recorder.
Next, the processing flow of the driving condition monitoring system will be explained step by step.
First, the process of transmitting driving status information in the drive recorder 2 will be described.
When the electric system of the vehicle starts, the drive recorder 2 starts operating (step S101). Each of the sensors 21 of the drive recorder 2 starts various sensing after the drive recorder 2 is started (step S102). Also, the camera 23 starts photographing (step S103). During the operation of the drive recorder 2, the vehicle information acquisition section 241 of the control device 24 acquires vehicle information (step S104). The vehicle information acquisition unit 241 may repeatedly acquire the sensing information included in the vehicle information at predetermined time intervals. Also, the position information acquisition unit 242 acquires the latitude and longitude from the GPS sensor 213 at predetermined time intervals (step S105). Further, the acceleration information acquisition unit 243 acquires acceleration from the acceleration sensor 211 at predetermined time intervals (step S106). Also, the authentication image data generation unit 249 generates authentication image data at predetermined time intervals based on the captured image acquired from the camera 23 . The predetermined time interval may be, for example, every 0.1 seconds. The authentication image data generating unit 249 may generate at a long time interval such as every minute, which is different from other sensing information. The driving situation data transmission unit 246 acquires vehicle information, position information (latitude, longitude), acceleration, and image data for authentication, and transmits the driving situation including the information, the time when the driving situation data was generated, and the ID of the drive recorder 2. Data is generated (step S107). The driving condition data transmission unit 246 requests the communication device 22 to transmit the driving condition data to the driving condition monitoring device 1 . The communication device 22 transmits the driving condition data to the driving condition monitoring device 1 (step S108). The control device 24 determines whether the process is finished (step S109), and repeats the process from step S102 until the process is finished.

FIG. 7 is a second diagram showing the processing flow of the drive recorder.
The drive recorder 2 performs event detection processing in parallel with the transmission processing of the driving status information. First, when the drive recorder 2 is started, the event detection unit 244 of the control device 24 acquires acceleration information from the acceleration information acquisition unit 243 at predetermined time intervals (step S201). Also, the event detection unit 244 acquires speed information from the vehicle information acquisition unit 241 at predetermined time intervals (step S202). The event detection unit 244 detects whether an event has occurred in the vehicle based on changes in acceleration and speed of the vehicle over time (step S203). An event is an event indicating a dangerous event in this embodiment. Detection of whether this event has occurred may be defined by driver attributes.

Specifically, the event detection unit 244 acquires the operating condition data described above. The risk level information included in this operating condition data holds an action flag for each acceleration corresponding to the risk. The dangerous driving type information included in the operating condition data holds an operation flag for each acceleration direction condition and speed condition corresponding to the dangerous driving type. The event detection unit 244 detects the occurrence of an event when the acceleration has a degree of risk indicating that the operation flag is "1" and the acceleration direction and speed conditions of the dangerous driving type indicating that the operation flag is "1" are met. The event detection unit 244 detects an event when at least one of the acceleration with the degree of danger indicating "1" in the operation flag or the acceleration direction and speed conditions of the dangerous driving type indicating the operation flag indicating "1" is met. The occurrence may be detected. Since the action flags held in the risk level information and the dangerous driving type information are set according to the driver's attribute, it is possible to detect the occurrence of an event based on the driver's attribute.

When the event detection unit 244 detects the occurrence of an event, it instructs the upload image generation unit 245 to generate upload image data. The upload image generation unit 245 acquires the captured image captured by the camera 23 of the drive recorder 2 . When the event detection signal is input from the event detection unit 244, the upload image generation unit 245 generates upload image data based on the captured image (step S204). Specifically, the upload image generation unit 245 generates a still image or a moving image of a predetermined playback time. The number of still images, the shooting time based on the event occurrence time of the still image, the playback time of the video image, and the time to match the video start timing based on the event occurrence time of the video image are determined according to the driver attributes. It's okay. The upload image generation unit 245 temporarily stores the upload image data including the generated still image or moving image, the generation time, and the ID of the drive recorder 2 (step S205). The upload image generation unit 245 may delete upload image data that has passed a predetermined period of time, such as one week before, from generation.

When the event detection unit 244 detects the occurrence of an event, it generates event data (step S206). The event data may include the acceleration, velocity, event occurrence time, and ID of the drive recorder 2 when the event occurrence is detected. Event data may include vehicle location information (latitude, longitude) and other sensing information. The event data transmission unit 247 acquires event data from the event detection unit 244 . The event data transmission unit 247 instructs the communication device 22 to transmit the event data to the driving condition monitoring device 1 . The communication device 22 transmits the event data to the driving condition monitoring device 1 (step S207). The control device 24 determines whether the process is finished (step S208), and repeats the process from step S202 until the process is finished.

FIG. 8 is a diagram showing a processing flow of the driving condition monitoring device.
In the driving situation monitoring device 1, the sensing data acquisition unit 12 acquires the driving situation data transmitted by the vehicle communication device 22 via the communication module 105 (step S301). Also, the sensing data acquisition unit 12 acquires the event data transmitted by the communication device 22 of the vehicle via the communication module 105 (step S302). The driver ID specifying unit 15 acquires authentication image data included in the driving situation data. The driver ID identification unit 15 generates facial feature information from the image included in the authentication image data. The driver ID identification unit 15 sequentially acquires information on combinations of driver IDs and facial feature information for a plurality of drivers recorded in advance in the database 104 . The driver ID specifying unit 15 calculates the matching degree between the facial feature information acquired from the database 104 and the facial feature information generated based on the authentication image data. A well-known calculation method may be used as a method for calculating the degree of matching. The driver ID identifying unit 15 performs authentication for identifying one or more driver IDs linked to facial feature information used to calculate a degree of matching equal to or greater than a predetermined threshold from the driver IDs acquired from the database 104. process. The driver ID specifying unit 15 performs an authentication process to determine whether the driver ID has been specified based on the degree of matching (step S303). Specifically, when there is one specified driver ID, the driver ID specifying unit 15 specifies the driver ID if the degree of matching calculated in specifying the driver ID is equal to or greater than a predetermined threshold value. Then, it is determined that the authentication is successful (step S304). If there are a plurality of specified driver IDs, the driver ID specifying unit 15 specifies one driver ID from among them and determines that the authentication is successful. Specifically, the driver ID specifying unit 15 calculates the average value of the degree of matching used to specify each driver ID for each driver ID. The driver ID specifying unit 15 specifies the driver ID with the highest average value of the degree of matching as the driver ID of the driver who drives the vehicle. After identifying the driver ID corresponding to the driving situation data acquired from the drive recorder 2 , the driver ID identification unit 15 outputs the driver ID to the recording unit 16 . The recording unit 16 associates the driver ID, the driving situation data, and the ID of the drive recorder 2 included in the driving situation data, and records them in the database 104 (step S305).

The dangerous driving data generator 13 detects the occurrence of an event in the vehicle equipped with the drive recorder 2 based on the event data (step S306). When the event occurrence is detected, the dangerous driving data generator 13 analyzes the vehicle information at the event occurrence time based on the event occurrence time (step S307). For example, the event occurrence time may be one minute before and after the event occurrence time. The dangerous driving data generation unit 13 calculates the event occurrence time specified by each time of 1 minute before and 1 minute after the event occurrence time, and generates information (vehicle information, position information, acceleration etc.) from the received driving situation data. The dangerous operation data generator 13 acquires the ID of the drive recorder 2 included in the event data. Based on the ID of the drive recorder 2, the dangerous driving data generator 13 reads the driver ID recorded in step S305 from the database 104. FIG. The dangerous driving data generation unit 13 acquires analysis conditions that are stored in advance in association with the ID of the drive recorder 2 and the driver ID. Since the analysis conditions are specified by the ID of the drive recorder 2 or the driver ID, analysis conditions corresponding to the company or individual driver using the drive recorder 2 installed in the vehicle can be obtained. The ID of the drive recorder 2 and the driver ID are one aspect of information indicating driver attributes.

The dangerous driving data generator 13 analyzes information (hereinafter referred to as extracted information) extracted from the driving situation data based on the event occurrence time based on the analysis conditions, and generates dangerous driving data as the analysis result (step S308). The analysis conditions include information used for analysis, information indicating the range indicated by the value of the information, information indicating the analysis method, and the like. The dangerous operation data generation unit 13 analyzes the extracted information based on the analysis method indicated by the analysis conditions, and determines whether or not the event is an important event. As an example, the analysis conditions may be conditions defined by the operating condition data described above. When the extracted information includes the acceleration that causes the operation flag to be "1", the dangerous driving data generation unit 13 reads the vehicle speed at each time at a predetermined interval during the event occurrence time from the extracted information. The dangerous driving data generation unit 13 identifies the dangerous driving type based on the transition of the acceleration and speed during the event occurrence time. When the operation flag corresponding to the specified danger type indicates "1", the dangerous driving data generation unit 13 generates dangerous driving data including the identification information of the danger type. Dangerous driving data may include acceleration, speed, and other information extracted from driving situation data at the time of event occurrence. The output unit 19 acquires the generated dangerous operation data. The output unit 19 records the dangerous driving data in a storage unit such as the database 104 in association with the ID of the drive recorder 2 and the driver ID (step S309).

Also, the dangerous driving data generation unit 13 determines whether to upload an image based on the identified risk type (step S310). Image upload determination conditions are determined based on driver attributes such as the ID of the drive recorder 2 and the driver ID, and may be stored in the driving situation monitoring device 1 in advance. When the specified risk type is a risk type that requires an image to be uploaded, the dangerous driving data generation unit 13 outputs an image acquisition request including at least the ID of the drive recorder 2 and the event occurrence time to the image acquisition unit 14 . . When the image acquisition request is input from the dangerous driving data generation unit 13, the image acquisition unit 14 sends the image acquisition request to the communication address of the drive recorder 2 that is specified in advance in association with the ID of the drive recorder 2 via the communication module 105. is transmitted (step S311).

The control device 24 of the drive recorder 2 receives the image acquisition request. Then, the upload image transmission unit 248 of the control device 24 temporarily uploads the upload image data corresponding to the time included in the event occurrence time extracted from the image acquisition request, among the upload image data generated by the upload image generation unit 245. It is specified from the uploaded image data to be stored. The upload image transmission unit 248 waits for transmission of the specified upload image data and temporarily stores it in a buffer or the like. For example, when the electrical system of the vehicle is restarted and the driving situation monitoring device 1 is restarted, the upload image transmission unit 248 transmits uploaded image data temporarily stored in a buffer and waiting for transmission. It is transmitted to the driving condition monitoring device 1 via the device 22 . The image acquisition unit 14 acquires the uploaded image data transmitted from the drive recorder 2 (step S312). The image acquisition unit 14 records the uploaded image data in association with the already generated dangerous driving data (step S313).

Through the above processing, the driving situation monitoring device 1 can generate and store the dangerous driving data and the uploaded image data according to the driver's attribute. According to the above-described processing, the uploaded image data is part of the still image or moving image data of the captured moving image generated according to the driver's attribute. Therefore, it is possible to reduce the amount of uploaded image data to be transmitted to the driving condition monitoring device 1 . In addition, the drive recorder 2 transmits the uploaded image data to the driving condition monitoring device 1 when it is restarted. Therefore, upload image data, which may have a large volume, during the time period when the vehicle is likely to be stopped and the communication quality is likely to be stable due to the vehicle being stopped. It can be transmitted to the driving condition monitoring device 1 .

If a driver ID whose degree of matching or the average value thereof is equal to or greater than a predetermined threshold is not obtained in the process of step S303 described above, it is determined whether or not the authentication process has been performed a predetermined number of times (step S321). If the authentication process has not been performed the predetermined number of times, the driver ID identification unit 15 repeats the authentication process in step S303 using the authentication image data included in the next driving situation data. If the driver ID identification unit 15 has performed the authentication process a predetermined number of times or more, it determines that the authentication has failed (step S322). If the driver ID identifying unit 15 determines that the authentication has failed, it generates a temporary ID (step S323). After generating the temporary ID, the driver ID identification unit 15 outputs the driver ID to the recording unit 16 . The recording unit 16 links the temporary ID, the driving situation data, and the ID of the drive recorder 2 included in the driving situation data, and records them in the database 104 (step S324). After that, the process transitions to step S306.

The driver ID identification unit 15 notifies the administrator of the provisional ID generated in step S323 at a predetermined timing. For example, the driver ID specifying unit 15 transmits screen information including the temporary ID and the recording destination URL of the driving situation data recorded in the database 104 linked to the temporary ID to the administrator's terminal screen at a predetermined time. As a result, screen information including the temporary ID and the recording destination URL is displayed on the administrator's terminal. The administrator accesses the driving situation data based on the recording destination URL, and displays images of authentication image data and upload image data included in the data. Based on the face image in the image, the manager determines whether the driver is a driver whose face image feature information has already been recorded in the database 104 . When the feature information of the face image of the driver is already recorded in the database 104, the manager performs an operation to rewrite the temporary ID recorded in the database 104 with the driver ID of the specified driver. The administrator inputs the temporary ID and the driver ID to the driving situation monitoring device 1, and the driver ID identification unit 15 identifies the temporary ID recorded in the database 104 based on the administrator's operation. A process of rewriting to the driver ID of the driver input together with the driver may be performed.

If the feature information of the face image of the driver is not recorded in the database 104, the administrator identifies the driver displayed in the authentication image data or the uploaded image data, and assigns the driver to the driver. Issue an ID. The administrator performs an operation to rewrite the temporary ID recorded in the database 104 with the driver ID of the newly issued driver. The manager inputs the provisional ID and the newly issued driver ID to the driving situation monitoring device 1, and the driver ID identification unit 15 identifies the provisional ID recorded in the database 104 based on the manager's operation. , a process of rewriting to the driver ID of the driver input together with the temporary ID may be performed.

According to the above-described process, the driving situation monitoring device 1 can identify the driver's ID based on the received authentication image data. As a result, the driving situation monitoring device 1 does not allow the drive recorder 2 to recognize identification information such as the driver's own ID by inserting a memory card into the drive recorder 2 or the like. can be recognized.
Then, the driver ID specified based on the photographed image of the driver, the operation status data, and the uploaded image data are linked and recorded in the database 104, so that the ID of the person different from the actual driver is recorded in the drive recorder. 2, management can be performed so that the ID of a different person and the operation status data are linked and recorded in the database 104 by mistake or disguise.
Also, even if the driver ID cannot be specified in the authentication image data based on the photographed image of the driver, a temporary ID is issued and notified to the administrator. can be linked to and recorded.
Then, it is possible to monitor the driving conditions of each driver who drives a plurality of vehicles, and accurately manage the data acquired from the drive recorder 2 for each driver.

The warning information generator 18 of the driving situation monitoring device 1 generates warning information including at least the danger type specified by the dangerous driving data generator 13 and the ID of the drive recorder 2 that transmitted the driving situation data (step S314). The output unit 19 acquires the warning information generated by the warning information generation unit 18 . The output unit 19 transmits the warning information to the communication address of the drive recorder 2 specified in advance in association with the ID of the drive recorder 2 via the communication module 105 (step S315). The drive recorder 2 receives the warning information. Upon receiving the warning information, the drive recorder 2 may output according to the danger type included in the warning information. For example, the drive recorder 2 emits sounds and voices according to the danger type. Accordingly, it is possible to issue a warning to the user according to the danger type.

The report generation unit 17 of the driving situation monitoring device 1 determines whether or not to generate the report data at a predetermined timing (step S316), and when the predetermined timing is reached, the report data corresponding to the driver is generated. Generate (step S317). The generation timing of the report data is, for example, once a day at a predetermined time such as 24:00. As a specific example of generating the report, for example, the report generating unit 17 acquires the ID dangerous driving data and the uploaded image data of the drive recorder 2 linked to one driver ID recorded in the storage unit such as the database 104. do. Based on at least one of the driver ID and the ID of the drive recorder 2, the report generation unit 17 acquires a pre-stored report generation condition. The report generation conditions include information such as the type of information to be included in the report and the destination of the report. The report generation unit 17 generates report data based on the report generation conditions. The report document data includes, for example, idling time indicating the time since the start of the vehicle included in the vehicle information, a radar chart corresponding to the number of occurrences for each risk type, and a report creation unit based on the risk type and the number of occurrences thereof. 17, the risk ranking aggregated by the report generation unit 17 according to the score, and the like. When the report data is generated, the output unit 19 acquires the report data and transmits it to the destination address based on the corresponding driver ID and drive recorder 2 ID (step S318). The control unit 11 of the driving condition monitoring device 1 determines whether the process is finished (step S319), and repeats the process from step S302 until the process is finished.

Through the above processing, the driving situation monitoring device 1 can generate report data corresponding to the driver's attribute and transmit it to a desired destination.
