Embodiment 1
(Configuration of Driving Skill Evaluation Device 1 and Driving Skill Evaluation System 400)
With reference to FIG. 1, the structure of the driving skill evaluation apparatus 1 and the driving skill evaluation system 400 is demonstrated. FIG. 1 is a block diagram showing the configuration of the driving skill evaluation device 1 and the driving skill evaluation system 400. As shown in FIG. 1, the driving skill evaluation device 1 includes a traveling state acquisition unit 14, a reference data acquisition unit 4, a captured image acquisition unit 5, a behavior acquisition unit 6, and a driving skill evaluation unit 7. The traveling state acquisition unit 14 includes a position information acquisition unit 2 and a vehicle behavior acquisition unit 3.

  The driving skill evaluation system 400 includes a driving skill evaluation device 1, a camera 8 (imaging unit), and a notification unit 9.

  In the present embodiment, the driving skill evaluation device 1, the camera 8, and the notification unit 9 are provided in the host vehicle 100. In addition, if the camera 8 is provided so that the area | region including the driver | operator's face of the own vehicle 100 or another vehicle can be imaged, and the notification part 9 is provided so that it can notify or display to the driver 200, The other members may be provided either on the vehicle or outside the vehicle.

  The driving skill evaluation device 1 can be configured as a drive recorder including a camera 8, for example. The driving skill evaluation device 1 may be a smartphone equipped with a camera 8 in which a program described later is installed.

  The captured image acquisition unit 5 acquires a captured image captured by the camera 8 and supplies the captured image to the behavior acquisition unit 6.

  FIG. 2 shows an example of imaging by the camera 8. The camera 8 provided in the host vehicle 100 images the area 300 including the head of the driver 200. The region 300 may be a region including at least the head of the driver 200, but may be a region including a part of the driver 200's head and chest. When the camera 8 captures an area including a part of the head and the chest of the driver 200, the behavior acquisition unit 6 to be described later performs not only a behavior based on a captured image of the head but also a part of the head and the chest. It is possible to acquire the behavior of the driver 200 including The region 300 may be a region that includes the hand of the driver 200. Further, the region 300 may be a region including the faces of passengers other than the driver 200. In addition, a passenger | crew is not limited to a human being, For example, creatures, such as a pet, are also included.

  Moreover, the camera 8 may image a driver of another vehicle. When the camera 8 images the driver 200 of the own vehicle 100, the camera 8 images the area 300 in the own vehicle, but when imaging the driver of another vehicle, the camera 8 images the outside of the own vehicle. When the camera 8 images the driver of the other vehicle, the driving skill evaluation unit 7 can evaluate the driving skill of the driver of the other vehicle, as will be described later.

  The camera 8 may acquire a plurality of captured images at different times. According to this configuration, the behavior acquisition unit 6 described later can more accurately acquire the behavior of the driver 200 with reference to a plurality of captured images captured at different times by the same camera 8. .

  The imaging unit is an optical detection element, and may be a camera capable of imaging outside the visible light region in addition to a camera capable of imaging in the visible light region. A plurality of cameras 8 may be provided for one driving skill evaluation device 1. In the present embodiment, the imaging unit is provided in the host vehicle 100, but a mode in which the imaging unit is provided in another vehicle is also within the scope of the present embodiment.

  The behavior acquisition unit 6 specifies the behavior of the driver 200 with reference to the captured image, and acquires the behavior. The behavior acquisition unit 6 supplies the acquired behavior to the driving skill evaluation unit 7. More specifically, the behavior acquisition unit 6 acquires at least one of the line of sight of the driver 200, the face orientation, and the hand movement as the behavior of the driver 200 based on the captured image. When the behavior acquisition unit 6 acquires the movement of the hand of the driver 200, the driving skill evaluation unit 7 described below can evaluate whether the driver 200 is not driving while operating the smartphone, for example.

  In addition to the behavior of the driver 200, the behavior acquisition unit 6 may acquire the behavior of an occupant other than the driver 200. For example, when the behavior acquisition unit 6 acquires the child's face of the driver 200 and the face of a pet or the like, the driving skill evaluation unit 7 described later evaluates whether the driver 200 is driving while holding the child and the pet. be able to.

  In the present application, the term “behavior” simply refers to the behavior of a driver other than the driver of the host vehicle 100 or other vehicle and the driver of the host vehicle 100 or other vehicle, and “vehicle behavior” indicating the behavior of the vehicle. Clearly distinguish.

  The behavior acquisition unit 6 may acquire the behavior of the driver 200 when the driver 200 is not driving the host vehicle 100 as well as when the driver 200 is driving the host vehicle 100. For example, when the behavior acquisition unit 6 acquires the behavior before the driver 200 starts driving or when the driver 200 pauses the driving, the driving skill evaluation unit 7 described later makes the driver 200 suitable for driving. It is possible to determine in advance that there is no state (extreme tension, seizure, panic, etc.). Moreover, when the camera 8 images the driver of another vehicle, the behavior acquisition unit 6 acquires the behavior of the driver of the other vehicle.

  The position information acquisition unit 2 acquires the position information of the host vehicle 100 and map information and supplies them to the vehicle behavior acquisition unit 3. The position information acquisition unit 2 acquires position information of the host vehicle 100 and map information using, for example, GPS (Global Positioning System). When the behavior acquisition unit 6 acquires the behavior of the driver of the other vehicle, the position information acquisition unit 2 acquires the position information and map information of the other vehicle. Further, when the vehicle behavior can be predicted from the position information of the host vehicle 100 and the map information, the position information acquisition unit 2 sends the position information of the host vehicle 100 and the map information to the reference data acquisition unit 4 and the output unit 15. You may supply.

  Note that the travel route of the host vehicle 100 is determined in advance, and the position information acquisition unit 2 may acquire the position information of the host vehicle 100 with reference to the travel route. According to this configuration, the driving skill evaluation unit 7 can evaluate the driving skill of the driver 200 in a travel route suitable for evaluation of the driving skill, for example.

  The vehicle behavior acquisition unit 3 refers to position information of the host vehicle 100 and information related to the behavior of the host vehicle 100 to acquire the vehicle behavior of the host vehicle 100 and supplies it to the reference data acquisition unit 4. The information related to the behavior of the host vehicle 100 may be control information of the host vehicle 100 acquired using a digital tachograph or the like, or a captured image of a situation outside the host vehicle acquired using an imaging unit such as a drive recorder. The control information of the host vehicle 100 includes, for example, the yaw rate, speed, acceleration, jerk (change in acceleration with time) of the host vehicle 100, light on / off, shift lever position, parking brake on / off, left and right Examples include turn signal on / off and foot brake on / off.

  Examples of the vehicle behavior acquired by the vehicle behavior acquisition unit 3 include straight ahead, right / left turn, lane change, temporary stop, parking / stopping, leaving, turning, and reverse. The vehicle behavior acquisition unit 3 acquires the vehicle behavior or predicts the vehicle behavior that will occur later by referring to the acquisition of the position information of the host vehicle 100 and the map information. For example, when the host vehicle 100 is located on a right turn road and the host vehicle 100 is operated in a clockwise direction, the vehicle behavior acquisition unit 3 determines that the host vehicle 100 is turning right. Judge. Further, for example, when the host vehicle 100 is located on a straight road without a side road and the host vehicle 100 is traveling, the vehicle behavior acquisition unit 3 determines that the host vehicle 100 is traveling straight, and It is predicted that the vehicle 100 will continue to go straight for a while.

  In the present application, the traveling state of the host vehicle 100 refers to position information of the host vehicle 100 and vehicle behavior. The reference data acquisition unit 4 to be described later may acquire reference data as a traveling state of the host vehicle 100 by referring to both the position information and the vehicle behavior of the host vehicle 100, or only the position information of the host vehicle 100. Alternatively, reference data may be acquired by referring to only vehicle behavior.

  The reference data acquisition unit 4 acquires reference data corresponding to the vehicle behavior. The reference data is data indicating a criterion as to whether or not the driver is performing an appropriate behavior corresponding to each vehicle behavior. For example, when the vehicle behavior acquisition unit 3 acquires a lane change as a vehicle behavior, the reference data acquisition unit 4 acquires data for sufficiently checking the surrounding safety as reference data corresponding to the lane change. The user can set the reference data based on basic operations such as safety confirmation required in a general driving license skill test, for example. For example, the user can set reference data based on exemplary behaviors when turning left and right at intersections, passing through signalized intersections, temporarily stopping, etc. according to traffic regulations. The user may set different reference data depending on the vehicle type such as a bus or a normal passenger car. Details of the reference data will be described later with an example.

  The driving skill evaluation unit 7 evaluates the driving skill of the driver 200 by comparing the reference data and the behavior of the driver 200 with reference to the reference data and the behavior of the driver 200. The method for evaluating the driving skill will be described later with an example. The driving skill evaluation unit 7 supplies the evaluation result of the driving skill to the output unit 15.

  The driving skill evaluation unit 7 may calculate a driving skill score obtained by digitizing the evaluation result of the driving skill of the driver 200. The method for calculating the driving skill score is not particularly limited. For example, the driving skill evaluation unit 7 scores each behavior of the driver 200 based on the difference between the behavior of the driver 200 and the reference data. Can be calculated.

  The driving skill evaluation unit 7 may identify an improvement point related to the behavior of the driver 200 and supply the improvement point to the notification unit 9. For example, the driving skill evaluation unit 7 refers to the evaluation result of the behavior of the driver 200 corresponding to each vehicle behavior, identifies the behavior whose evaluation is below a predetermined value, and supplies the behavior to the notification unit 9. The notification unit 9 may advise the driver 200 to improve the behavior. As a result, the driver 200 can learn the improvement points related to his / her behavior and use it to improve the driving skill.

  In addition, although not shown in figure, the output part 15 may supply the evaluation result of a driving skill to a data server. The data server may be connected to a plurality of vehicles via a network. In that case, the data server acquires the evaluation result of the driving skill from the host vehicle 100 and the plurality of vehicles, and stores the evaluation result of the driving skill. In this case, the driving skill evaluation unit 7 receives the evaluation result of the driving skill for a plurality of vehicles from the data server. According to this configuration, the driving skill evaluation unit 7 can calculate the threshold value and reference data for evaluating the driving skill with reference to the driving skill evaluation results for a plurality of vehicles. The data server may be provided in the vehicle or may be provided separately from the vehicle.

  The output unit 15 supplies the evaluation result of the driving skill to the notification unit 9. Note that the output unit 15 may be a device that transmits information to the notification unit 9 by, for example, wired or wireless.

  The notification unit 9 notifies the driver 200 of the evaluation result of the driving skill of the driver 200 received from the output unit 15. The notification unit 9 may be a display unit that performs notification by video, may be a speaker that performs notification by audio, or may be a vibration generator that performs notification by vibration. When the notification unit 9 performs notification by voice, the notification sound may be changed depending on the behavior type of the driver 200. The notification unit 9 may change the notification sound according to the evaluation result of the behavior of the driver 200.

  Although the timing which the notification part 9 performs notification is not specifically limited, For example, it may be every time the behavior of the driver 200 is evaluated, and may be every predetermined period. A method of notifying the driver 200 by the notification unit 9 will be described later with an example.

  Further, the notification unit 9 may notify the driver 200 of information related to the road form of the travel route with reference to the position information and map information of the host vehicle 100 supplied from the position information acquisition unit 2. The information regarding the road form includes, for example, information such as the right or left turn ahead. Thereby, the notification unit 9 can assist the driving operation of the driver 200. In addition, the notification unit 9 may notify the driver 200 of points to be noted in traveling.

  The notification part 9 should just be provided so that notification to the driver 200 of the own vehicle 100 can be performed. The notification unit 9 is provided in the host vehicle 100, for example. In the present embodiment, the notification unit 9 is provided outside the driving skill evaluation device 1, but the notification unit 9 may be provided in the driving skill evaluation device 1. A plurality of notification units 9 may be provided. For example, the notification unit 9 is provided in the host vehicle 100, and a personal computer independent of the host vehicle 100, a smartphone, or the like may be used as the notification unit 9.

(Example of driving skill evaluation method)
With reference to FIG. 3, the example of the evaluation method of a driving skill is demonstrated. FIG. 3 is a diagram for explaining an example of the driving skill evaluation method according to the present embodiment. FIG. 3A is a table showing an example of reference data. FIG. 3B is a table showing an example of driving skill evaluation by the driving skill evaluation unit 7.

  As shown in FIG. 3 (a), the reference data acquired by the reference data acquisition unit 4 can be used by the driver when the vehicle behavior is a right turn, a left turn, or a lane change in this example. It is data indicating the criterion of whether or not.

  When the vehicle behavior indicates a right turn, the reference data acquisition unit 4 indicates that the line of sight of the driver 200 is directed to 30 ° or more to the right with respect to the traveling direction of the host vehicle 100, and the face direction is the traveling direction of the host vehicle 100. As a reference data, the direction of 10 ° to the right is obtained as reference data. Hereinafter, the line of sight and the face direction of the driver 200 will be described using angles based on the traveling direction of the host vehicle 100.

  When the vehicle behavior indicates a left turn, the reference data acquisition unit 4 acquires, as reference data, that the line of sight of the driver 200 is 30 ° or more left and the face is 10 ° or more left.

  When the vehicle behavior indicates a lane change, the reference data acquisition unit 4 turns the driver's 200 line of sight toward the lane change side by 30 ° or more, and the face direction changes by 10 ° toward the lane change side. The fact that it is suitable for the above is acquired as reference data.

  As shown in FIG. 3B, the driving skill evaluation unit 7 refers to the behavior of the driver 200 and the reference data, and evaluates whether the driver 200 has sufficiently performed safety checks corresponding to each vehicle behavior. To do. The driving skill evaluation unit 7 evaluates the evaluation as being mal if the line of sight and the face direction of the driver 200 exceed the reference data described above. The driving skill evaluation unit 7 evaluates the evaluation as long as the line of sight and the face direction of the driver 200 are below the reference data described above. The driving skill evaluation unit 7 evaluates the driving skill of the driver 200 on the basis of the number of behaviors evaluated as round for all the number of behaviors evaluated. The driving skill evaluation unit 7 evaluates that the driving skill of the driver 200 is higher as the number of points increases.

  Note that the reference data and the threshold are set in advance, for example. Or reference data and a threshold value can also be set as the structure which the driving skill evaluation part 7 determines with reference to the evaluation result of the driving skill accumulate | stored in the data server.

(Notification example of driving precautions to the driver)
With reference to FIG. 4, an example of notifying the driver 200 of points to be noted when traveling by the notification unit 9 will be described. FIG. 4 is a diagram illustrating an example of notification of points of caution in traveling to the driver 200 by the notification unit 9. FIG. 4A is a diagram illustrating an example of notification of travel points when the host vehicle 100 makes a left turn, and FIG. 4B is a diagram illustrating an example of notifications of travel points when the host vehicle 100 makes a right turn. Note that the travel precautions notified by the notification unit 9 here may cause the driver 200 to confirm an appropriate behavior to be performed by the driver 200 corresponding to each vehicle behavior. For example, as shown in the right diagrams of FIGS. 4A and 4B, the notification unit 9 notifies the driver 200 of an appropriate line of sight and face orientation when making a left turn and a right turn.

  As shown in FIG. 4, the notification unit 9 refers to the position information and map information of the host vehicle 100 supplied from the position information acquisition unit 2, for example, and points to note on traveling according to the road form of the traveling route. The driver 200 can be notified before or after.

  The notification unit 9 may transmit the notification information to a terminal device possessed by the driver 200, and the terminal device may notify the driver 200 based on the notification information. At that time, the terminal device may notify the driver 200 of the notification information by display, or may notify by a combination of display and sound.

(Example of notification of driving skill evaluation results)
With reference to FIG. 5, the notification example of the evaluation result of the driving skill by the notification unit 9 will be described. FIG. 5 is a diagram illustrating a notification example of the evaluation result of the driving skill by the notification unit 9. FIG. 5A is a diagram illustrating a notification example when the behavior of the driver 200 at the time of a left turn is appropriate. FIG. 5B is a diagram illustrating a notification example when the behavior of the driver 200 at the time of a left turn is inappropriate.

  In this example, the notification unit 9 refers to the evaluation result of the driving skill and displays whether or not the behavior of the driver 200 corresponding to each vehicle behavior is appropriate every time the evaluation result for each behavior is received. In addition to displaying the notification examples shown in FIGS. 5A and 5B on the display screen, the notification unit 9 may notify by voice. In this example, since the notification unit 9 notifies the driver 200 of the evaluation result every time the behavior evaluation result is received, the driver 200 can know in real time whether or not his / her behavior is appropriate, thereby improving the driving skill. Can be useful.

(Usage example)

There can be usages such as writing.

(Flow of driving skill evaluation process)
The flow of the driving skill evaluation process will be described with reference to FIG. FIG. 6 is a flowchart showing the flow of the driving skill evaluation process. In the following, in order to simplify the description, it is assumed that the driving skill evaluation device 1 acquires only a right / left turn as the vehicle behavior of the host vehicle 100. Details of each process are as described above.

(Step S002)
First, in step S <b> 002, the captured image acquisition unit 5 acquires a captured image including the driver's head from the camera 8. The captured image acquisition unit 5 supplies the acquired captured image to the behavior acquisition unit 6.

(Step S004)
Next, in step S004, the behavior acquisition unit 6 detects the behavior of the driver 200 including the line of sight of the driver 200 and the face direction with reference to the captured image. The behavior acquisition unit 6 supplies the behavior of the driver 200 to the driving skill evaluation unit 7.

  In addition, the order which performs step S004 is not limited except that it is before step S012.

(Step S008)
Next, in step S008, the position information acquisition unit 2 acquires the position information and map information of the host vehicle 100. The position information acquisition unit 2 supplies the acquired position information and map information to the vehicle behavior acquisition unit 3.

(Step S010)
Next, in step S010, the vehicle behavior acquisition unit 3 acquires the vehicle behavior of the host vehicle 100 with reference to the position information. When the vehicle behavior acquisition unit 3 acquires a right / left turn of the vehicle, the process of step S012 is subsequently performed. If the vehicle behavior acquisition unit 3 has not acquired a right or left turn of the vehicle, the process returns to step S002.

(Step S012)
Next, in step S012, the vehicle behavior acquisition unit 3 supplies the vehicle behavior to the reference data acquisition unit 4. The reference data acquisition unit 4 refers to the vehicle behavior and acquires reference data corresponding to the right / left turn. The reference data acquisition unit 4 supplies the reference data to the driving skill evaluation unit 7.

  The driving skill evaluation unit 7 refers to the behavior of the driver 200 and the reference data, and evaluates whether or not the driver 200 can sufficiently confirm the surrounding safety when making a right / left turn. If the driver 200 has performed sufficient safety confirmation, the process of step S014 is subsequently performed. If the driver 200 has not performed sufficient safety confirmation, the process of step S016 is subsequently performed.

(Step S014)
Next, in step S014, the driving skill evaluation unit 7 supplies the output unit 15 with information that the driver 200 has performed sufficient safety confirmation. The output unit 15 supplies the notification unit 9 with information that the driver 200 has performed sufficient safety confirmation.

  The notification unit 9 notifies the driver 200 that sufficient safety confirmation has been performed by playing a voice announcement “I was able to do it” while displaying, for example, the display shown in FIG.

(Step S016)
Next, in step S <b> 016, the driving skill evaluation unit 7 supplies information indicating that sufficient safety confirmation has not been performed to the driver 200 to the output unit 15. The output unit 15 supplies the notification unit 9 with information that the driver 200 has not performed sufficient safety confirmation.

  For example, the notification unit 9 did not perform sufficient safety confirmation for the driver 200 by playing a voice announcement such as “Careful and dangerous” while displaying the display shown in FIG. 5B, for example. Notify that. Moreover, the notification part 9 may display the point which has not performed sufficient safety confirmation with respect to the driver 200, as shown in FIG.5 (b). In the example of FIG. 5B, since the driver 200 has not been able to visually confirm the left rear, the notification unit 9 displays the message “Let's visually confirm the left rear next” on the driver 200. .

(Step S018)
Next, in step S0018, if the camera 8 has stopped imaging, the captured image acquisition unit 5 cannot acquire a captured image, and thus the driving skill evaluation device 1 ends the driving skill evaluation process. If the camera 8 has not stopped imaging, the driving skill evaluation apparatus 1 returns to step S002. The driving skill evaluation device 1 repeats the processing from step S002 to step S018 unless the camera 8 stops imaging.
