[Explanation of vehicle management method]
Hereinafter, the vehicle management method executed by the vehicle management system S according to the present embodiment will be described in detail. First, the driver activates the driver application (vehicle management program) in the in-vehicle device 2. When the driver application is activated, the traveling state determination unit 231 repeatedly determines whether or not the vehicle is in the traveling state. For example, the traveling state determination unit 231 determines whether or not the vehicle is in a traveling state based on the speed, acceleration, gear state, or parking brake state acquired from a sensor provided in the vehicle. Further, the traveling state determination unit 231 determines whether or not the vehicle is in the traveling state based on the change in the position calculated based on the signal acquired from the GPS (Global Positioning System) receiver provided in the vehicle. You may.

When the traveling state determination unit 231 determines that the vehicle is in the traveling state, the acquisition unit 232 acquires the captured image of the driver captured by the imaging device 3. For example, the acquisition unit 232 acquires an captured image by transmitting an imaging instruction to the imaging device 3 at a timing when the traveling state determination unit 231 determines that the vehicle is in a traveling state. Further, the acquisition unit 232 captures the captured image taken at the time closest to the timing determined by the running state determination unit 231 that the vehicle is in the running state from the captured images periodically captured by the image pickup device 3. May be obtained. The first transmission unit 233 transmits the captured image acquired by the acquisition unit 232 to the vehicle management device 1.

FIG. 3 is a diagram showing an exemplary captured image IM1 acquired by the acquisition unit 232. The captured image IM1 is an image including at least a part of the driver (for example, the upper body of the driver) so that the driver can be identified and the posture of the driver can be determined.

In the vehicle management device 1, the receiving unit 131 receives the captured image transmitted by the vehicle-mounted device 2. The identification unit 132 identifies the driver of the vehicle based on the captured image received by the reception unit 131. For example, the storage unit 12 stores in advance an image of each of the plurality of drivers (or feature information extracted from the image) in association with identification information (user ID or the like) that can identify the driver. The specific unit 132 applies a known image recognition technology (person recognition technology) to the captured image received by the reception unit 131, so that a plurality of operations corresponding to the plurality of images stored in advance in the storage unit 12 can be performed. From the hands, identify the driver included in the captured image.

The generation unit 133 generates reference posture information indicating the reference posture of the driver specified by the specific unit 132. The reference posture is a posture that serves as a reference for determining whether or not the driver's posture is disturbed by the in-vehicle device 2 as described later. The reference posture is represented by the positions of multiple joints in the driver's body. For example, the generation unit 133 detects a known posture for each of a plurality of captured images received by the reception unit 131 from the in-vehicle device 2 in the past (for example, several days back from the present) for the driver specified by the specific unit 132. By applying the technology, the posture of the driver is detected. Then, the generation unit 133 specifies the detected statistical values (average value, median value, mode value, etc.) of the plurality of postures as the reference posture. Further, the reference posture may be common among a plurality of drivers. The reference posture information may be generated in advance and stored in the storage unit 12.

The transmission unit 134 transmits the driver information including the identification information that can identify the driver specified by the specific unit 132 and the reference posture information indicating the reference posture of the driver specified by the specific unit 132 to the in-vehicle device 2. do.

In the in-vehicle device 2, the receiving unit 234 receives the driver information transmitted by the vehicle management device 1. After the receiving unit 234 receives the driver information, the acquiring unit 232 repeatedly acquires the captured image of the driver captured by the imaging device 3. The posture determination unit 235 notifies the driver of the difference between the driver's posture indicated by the captured image acquired by the acquisition unit 232 and the reference posture indicated by the driver information received by the reception unit 234. Determine if the condition is met.

FIG. 4 is a schematic diagram for explaining a method in which the posture determination unit 235 determines the posture of the driver. The posture determination unit 235 detects the posture indicated by the captured image IM1 by applying a known posture detection technique to the captured image IM1 acquired by the acquisition unit 232. The posture indicated by the captured image IM1 is represented by the positions of a plurality of joints in the driver's body. The posture determination unit 235 calculates the difference between the posture indicated by the captured image IM1 and the reference posture P indicated by the driver information received by the reception unit 234 (for example, the average value of the differences in the positions of the joints). Then, the posture determination unit 235 determines that the notification condition is satisfied when the calculated difference is equal to or greater than a predetermined value, and determines that the notification condition is not satisfied otherwise. When the posture determination unit 235 determines that the notification condition is satisfied, the posture determination unit 235 causes the display unit 24 to display a predetermined notification. The posture determination unit 235 may notify the driver by outputting a predetermined voice.

FIG. 5 is a front view of the in-vehicle device 2 displaying the notification 241. Notification 241 includes a message indicating that the driver's posture is disturbed. As a result, the driver can know whether or not his / her posture is disturbed as compared with the reference posture, and can change the posture during driving.

The second transmission unit 236 acquires driving information regarding the driving of the vehicle by the driver. For example, driving information includes speed, acceleration, number of sudden accelerations and number of sudden brakings. For example, the second transmission unit 236 acquires the speed and acceleration from a sensor provided in the vehicle, and further calculates the number of sudden accelerations and the number of sudden brakings from the acquired acceleration. The second transmission unit 236 may acquire other information regarding the driving of the vehicle by the driver, such as information regarding the operation of the steering wheel and information regarding the operation of the direction indicator, as driving information. Further, the driving information may include a posture determination result determined by the posture determination unit 235.

The second transmission unit 236 transmits the acquired driving information to the vehicle management device 1 together with the captured image acquired by the acquisition unit 232. The second transmission unit 236 may sequentially transmit the acquired operation information, may periodically transmit the acquired operation information at predetermined time intervals, or may collectively transmit the acquired operation information at the end of the operation. Further, the second transmission unit 236 causes the display unit 24 to display a notification indicating that the continuous operation time is long when the acquired operation information indicates that the same driver has been operating for a predetermined time or longer. You may. The second transmission unit 236 may notify the driver by outputting a predetermined voice.

In the vehicle management device 1, the receiving unit 131 receives the driving information and the captured image transmitted by the vehicle-mounted device 2. The receiving unit 131 stores the driving information and the captured image received from the vehicle-mounted device 2 in the storage unit 12 in association with the driver (that is, the driver's identification information). The evaluation unit 135 evaluates the driver specified by the specific unit 132 based on the operation information received by the reception unit 131, and generates evaluation information indicating the evaluation result.

FIG. 6 is a schematic diagram for explaining a method in which the evaluation unit 135 evaluates the driver. For example, the evaluation unit 135 evaluates the safety, riding comfort, unevenness, etc. of the driver's driving of the vehicle based on the speed, acceleration, the number of sudden accelerations, and the number of sudden brakings included in the driving information. The driver's evaluation performed by the evaluation unit 135 is not limited to the specific items shown here. The evaluation unit 135 stores the evaluation information indicating the evaluation result in the storage unit 12 in association with the driver (that is, the driver's identification information).

At this time, the evaluation unit 135 evaluates the driver whose predetermined attribute is set in the driver information, and does not evaluate the driver whose predetermined attribute is not set in the driver information. The predetermined attribute is, for example, a flag indicating that the driver is the evaluation target. As a result, the vehicle management system S can reduce the processing load by evaluating only a specific driver and not evaluating other drivers.

In this way, since the vehicle management system S identifies the driver based on the captured image captured when the vehicle is in a running state, there is a high probability that the specified driver and the driver who is driving the vehicle will identify the driver. Match. Therefore, the vehicle management system S can record information on the driving of the vehicle by the driver identified with high accuracy in association with the driver.

Further, the vehicle management system S identifies the driver when the vehicle is in a traveling state, and then identifies the driver again when the driver can be replaced. FIG. 7 is a schematic diagram for explaining how the vehicle management system S identifies the driver again.

As described above, in the in-vehicle device 2, the receiving unit 234 is the driver specified based on the captured image IM1 acquired by the acquisition unit 232 when the traveling state determination unit 231 determines that the vehicle is in the traveling state. Receive driver information. After that, the traveling state determination unit 231 repeatedly determines whether or not the vehicle is in the paused state. For example, the traveling state determination unit 231 determines whether or not the vehicle is in the paused state based on the speed, acceleration, gear state, or parking brake state acquired from a sensor provided in the vehicle. Further, the traveling state determination unit 231 may determine whether or not the vehicle is in the paused state based on the change in the position calculated based on the signal acquired from the GPS receiver provided in the vehicle. ..

When the traveling state determination unit 231 determines that the vehicle is in the paused state, the acquisition unit 232 acquires the driver's image IM2 imaged by the image pickup device 3. The acquisition unit 232 determines whether or not the driver has performed a predetermined operation based on the captured image IM2 in the paused state. The predetermined operation is an operation in which the driver goes out of the imaging range of the imaging device 3. For example, the acquisition unit 232 detects the position of the driver's face based on the captured image IM2, and determines that the predetermined operation is performed when the driver's face is not within the range of the captured image IM2. The acquisition unit 232 may determine whether or not the driver has performed a predetermined operation outside the imaging range of the imaging device 3 by using an infrared sensor or the like provided in the vehicle without using the captured image IM2. ..

When the acquisition unit 232 determines that the driver has performed a predetermined operation, the traveling state determination unit 231 repeatedly determines whether or not the vehicle has entered the traveling state after being temporarily stopped. When the traveling state determination unit 231 determines that the vehicle has entered the traveling state after being temporarily stopped, the acquisition unit 232 acquires the captured image of the driver captured by the imaging device 3 again. The first transmission unit 233 retransmits the captured image (that is, the captured image in the traveling state) acquired again by the acquisition unit 232 to the vehicle management device 1.

In the vehicle management device 1, the receiving unit 131 receives the captured image transmitted again by the vehicle-mounted device 2. The identification unit 132 identifies the driver of the vehicle based on the captured image received by the reception unit 131. The transmission unit 134 transmits the driver information of the driver specified by the specific unit 132 to the in-vehicle device 2.

In the in-vehicle device 2, the receiving unit 234 receives the driver information specified by the vehicle management device 1 based on the captured image transmitted again by the first transmitting unit 233. As described above, when the vehicle is temporarily stopped and the driver performs a predetermined operation that can be replaced, the vehicle management system S reacquires the captured image in the traveling state and identifies the driver again. As a result, the vehicle management system S can continue to identify the driver with high accuracy. Since the in-vehicle device 2 transmits the captured image to the vehicle management device 1 on condition that the driver performs a predetermined operation during the temporary stop, the communication load can be reduced. Further, since it is determined whether or not the driver can be replaced on the vehicle-mounted device 2 side, the processing load of the vehicle management device 1 can be reduced.

In the above process, the first transmission unit 233 transmits the captured image acquired again by the acquisition unit 232 on the condition that the driver has performed the predetermined operation, but the detection of the driver's predetermined operation is omitted. You may. In this case, regardless of whether or not the driver has performed a predetermined operation, the traveling state determination unit 231 repeatedly determines whether or not the vehicle has entered the traveling state after being temporarily stopped. When the traveling state determination unit 231 determines that the vehicle has entered the traveling state after being temporarily stopped, the first transmitting unit 233 again transmits the captured image acquired by the acquiring unit 232 to the vehicle management device 1. do. Even in such a configuration, the vehicle management system S can continue to identify the driver with high accuracy.
