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

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 driving situation information transmission processing. First, when the drive recorder 2 starts, 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). The event detection unit 244 also 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 temporal changes in the acceleration and speed of the vehicle (step S203). In this embodiment, an event is an event indicating a dangerous event. Detection of whether this event has occurred may be determined by driver attributes.

Specifically, the event detection unit 244 acquires the above-mentioned operating condition data. The danger level information included in this operating condition data holds an operation flag for each acceleration according to the danger level. Further, the dangerous driving type information included in the operating condition data holds an operation flag for each acceleration direction condition and speed condition according to the type of dangerous driving. The event detection unit 244 detects the occurrence of an event when the acceleration is at a dangerous level where the operation flag is "1" and the acceleration direction and speed conditions match the dangerous driving type where the operation flag is "1". The event detection unit 244 detects an event in at least one of cases where the acceleration is at a dangerous level where the operation flag indicates "1", or when the acceleration direction and speed match the conditions of the dangerous driving type where the operation flag indicates "1". The occurrence may also be detected. Since the operation flags held in the risk level information and dangerous driving type information are set according to the driver attributes, it is possible to detect the occurrence of an event based on the driver attributes.

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 a captured image captured by the camera 23 of the drive recorder 2. When the upload image generation unit 245 receives the event occurrence detection signal from the event detection unit 244, it generates upload image data based on the acquired captured image (step S204). Specifically, the upload image generation unit 245 generates a still image or a moving image with 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, the time to adjust the video start timing based on the event occurrence time of the video image, etc. are determined according to the driver's attributes. It's okay to stay. The upload image generation unit 245 temporarily stores upload image data including the generated still images and moving images, 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 been generated for a predetermined period of time, such as one week ago.

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, speed, time of event occurrence, and ID of the drive recorder 2 when the event occurrence is detected. The event data may include vehicle position information (latitude, longitude) and other sensing information. The event data transmitter 247 acquires event data from the event detector 244. The event data transmitter 247 instructs the communication device 22 to transmit event data to the driving status monitoring device 1 . The communication device 22 transmits the event data to the driving status monitoring device 1 (step S207). The control device 24 determines whether the processing is completed (step S208), and repeats the processing from step S202 until the processing is completed.

FIG. 8 is a diagram showing a processing flow of the driving condition monitoring device.
In the driving condition monitoring device 1, the sensing data acquisition unit 12 acquires the driving condition data transmitted by the communication device 22 of the vehicle via the communication module 105 (step S301). Furthermore, the sensing data acquisition unit 12 acquires event data transmitted by the communication device 22 of the vehicle via the communication module 105 (step S302). The driver ID identification unit 15 acquires authentication image data included in the driving situation data. The driver ID identifying unit 15 generates facial feature information from the image included in the authentication image data. The driver ID specifying 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 identification unit 15 calculates the degree of matching between the facial feature information acquired from the database 104 and the facial feature information generated based on the authentication image data. A known calculation method may be used as the method for calculating the degree of matching. The driver ID identification unit 15 performs authentication to identify one or more driver IDs from the driver IDs obtained from the database 104 that are associated with the facial feature information used to calculate the degree of matching equal to or higher than a predetermined threshold. Perform processing. 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 the number of identified driver IDs is one, the driver ID identifying unit 15 identifies that driver ID if the degree of matching calculated in identifying that driver ID is greater than or equal to a predetermined threshold. It is determined that the authentication is successful (step S304). If there are a plurality of identified 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 identification unit 15 calculates, for each driver ID, the average value of the degree of matching used to identify each driver ID. The driver ID identifying unit 15 identifies the driver ID with the highest average value of matching degree as the driver ID of the driver who drives the vehicle. When the driver ID identifying unit 15 identifies the driver ID corresponding to the driving situation data acquired from the drive recorder 2, it outputs the driver ID to the recording unit 16. The recording unit 16 records the driver ID, the driving situation data, and the ID of the drive recorder 2 included in the driving situation data in the database 104 in association with each other (step S305).

The dangerous driving data generation unit 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 dangerous driving data generation unit 13 detects the event occurrence, it analyzes 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 the times one minute before and one minute after the event occurrence time, and generates information at the event occurrence time (vehicle information, position information, acceleration etc.) from the received driving status data. The dangerous driving data generation unit 13 acquires the ID of the drive recorder 2 included in the event data. Furthermore, the dangerous driving data generation unit 13 reads the driver ID recorded in step S305 from the database 104 based on the ID of the drive recorder 2. 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 and the driver ID, the analysis conditions can be obtained depending on the company or individual driver who uses the drive recorder 2 mounted on a vehicle, for example. The ID of the drive recorder 2 and the driver ID are one form of information indicating driver attributes.

The dangerous driving data generation unit 13 analyzes information extracted from the driving situation data (hereinafter referred to as extracted information) based on the event occurrence time based on 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, etc. The dangerous driving data generation unit 13 analyzes the extracted information based on the analysis method indicated by the analysis conditions, and determines whether the event is an important event or not. As an example, the analysis conditions may be conditions defined by the above-mentioned operating condition data. When the extracted information includes an acceleration that causes the operation flag to be "1", the dangerous driving data generation unit 13 reads the speed of the vehicle 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 at 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 identification information of the danger type. The dangerous driving data may include information extracted from acceleration, speed, and other driving situation data at the time when the event occurred. The output unit 19 acquires the generated dangerous driving 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).

Further, the dangerous driving data generation unit 13 determines whether to upload an image based on the specified risk type (step S310). The 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 status monitoring device 1 in advance. If the identified risk type is a risk type that requires image upload, 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 unit 14 receives an image acquisition request from the dangerous driving data generation unit 13, the image acquisition unit 14 sends an image acquisition request 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 S311).

The control device 24 of the drive recorder 2 receives the image acquisition request. Then, the upload image transmitter 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, from among the upload image data generated by the upload image generator 245. Specify from among the uploaded image data to be stored. The upload image transmitter 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 status monitoring device 1 is restarted, the upload image transmitter 248 transmits the upload image data that has been temporarily stored in the buffer and is waiting to be transmitted. It is transmitted to the driving status monitoring device 1 via the device 22. The image acquisition unit 14 acquires the upload 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 dangerous driving data and upload image data according to driver attributes. According to the above-described process, the upload image data is data of some still images or moving images of the captured moving images generated according to the driver attributes. Therefore, the amount of upload image data sent to the driving condition monitoring device 1 can be reduced. Further, the drive recorder 2 transmits upload image data to the driving status monitoring device 1 upon restart. Therefore, upload image data, which may have a large capacity, during times when there is a high possibility that the vehicle is stopped, and when the communication quality is likely to be stable because the vehicle is stopped. It can be transmitted to the driving status monitoring device 1.

In the process of step S303 described above, if a driver ID with a matching degree or an average value equal to or higher than a predetermined threshold cannot be obtained, it is determined whether the authentication process has been performed a predetermined number of times (step S321). If the driver ID identifying unit 15 has not performed the authentication process a predetermined number of times, it repeats the authentication process in step S303 using the authentication image data included in the next driving situation data. If the driver ID specifying unit 15 performs the authentication process a predetermined number of times or more, it determines that the authentication is unsuccessful (step S322). If the driver ID specifying unit 15 determines that the authentication is unsuccessful, it generates a temporary ID (step S323). After generating the temporary ID, the driver ID specifying unit 15 outputs the driver ID to the recording unit 16. The recording unit 16 records the temporary ID, the driving situation data, and the ID of the drive recorder 2 included in the driving situation data in the database 104 in association with each other (step S324). After that, the process transitions to step S306.

The driver ID specifying unit 15 notifies the administrator of the temporary 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 in association with the temporary ID to the administrator's terminal screen at a predetermined time. As a result, screen information including the temporary ID and recording destination URL is displayed on the administrator's terminal. The administrator accesses the driving status data based on the recording destination URL and displays images of the authentication image data and upload image data included in the data. Based on the facial image in the image, the administrator determines whether the driver is a driver whose facial image characteristic information has already been recorded in the database 104. If the characteristic information of the driver's face image is already recorded in the database 104, the administrator performs an operation to rewrite the temporary ID recorded in the database 104 to the driver ID of the specified driver. The administrator inputs the temporary ID and driver ID into the driving status monitoring device 1, and the driver ID specifying unit 15 inputs the temporary ID recorded in the database 104 based on the operation by the administrator. You may also perform a process of rewriting the driver ID of the driver input at the same time.

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

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 status monitoring device 1 can detect the driver's ID without the driver having to insert a memory card into the drive recorder 2 to make the drive recorder 2 recognize identification information such as his or her own ID. can be recognized.
The driver ID identified based on the captured image of the driver is linked to the driving status data and the uploaded image data and recorded in the database 104, so that the ID of a person different from the actual driver is recorded in the drive recorder. 2, it is possible to manage to prevent fraud such as erroneously or fraudulently linking a different person's ID and driving status data and recording them in the database 104.
In addition, even if the driver ID cannot be specified in the authentication image data based on the image taken by the driver, a temporary ID will be issued and the administrator will be notified. It can be recorded in association with.
The driving status of each driver driving a plurality of vehicles can be monitored, and the data acquired from the drive recorder 2 for each driver can be managed with precision.

The warning information generating unit 18 of the driving situation monitoring device 1 generates warning information including at least the danger type specified by the dangerous driving data generating unit 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 generating 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. When the drive recorder 2 receives the warning information, it may output according to the type of danger included in the warning information. For example, the drive recorder 2 emits sounds and voices depending on the type of danger. Thereby, a warning can be given to the user according to the type of danger.

The report generation unit 17 of the driving status monitoring device 1 determines whether to generate report data at a predetermined timing (step S316), and when the predetermined timing is reached, generates report data according to the driver. is generated (step S317). The report document data is generated at a predetermined time such as once a day at 24 o'clock, for example. A specific example of report generation is, for example, when the report generation unit 17 acquires the ID dangerous driving data and upload image data of the drive recorder 2 associated with one driver ID recorded in a storage unit such as the database 104. do. The report generation unit 17 acquires report generation conditions stored in advance based on at least one of the driver ID and the ID of the drive recorder 2. 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 report generation conditions. The report data includes, for example, idling time that indicates the time since the start of the vehicle included in the vehicle information, a radar chart according to the number of occurrences of each danger type, and a report generation unit based on the danger type and the number of occurrences thereof. 17, a risk ranking compiled by the report document generation unit 17 according to the scores, and the like. When the report document data is generated, the output unit 19 acquires the report document data and transmits it to the destination address based on the corresponding driver ID and the ID of the drive recorder 2 (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 document data according to driver attributes and transmit it to a desired destination.
