There is a state etc.

The driver's license reading unit 23 reads the driver's identification information from the driver's license held by the driver. The input unit 25 accepts the input operation of the driver.
The camera 26 is provided in the vehicle interior of the vehicle 7. The camera 26 takes a picture of the driver and generates an image. The image generated by the camera 26 will be referred to as a driver image below. The driver image represents, for example, the upper body including the driver's face.

The communication unit 27 communicates with the safe driving diagnostic device 5 via the Internet 31. The database 29 can store information.
The safe driving diagnostic device 5 is fixedly installed outside the vehicle 7. The safe driving diagnosis device 5 includes a control unit 33, an input unit 34, a communication unit 35, and a database 37. The control unit 33 includes a microcomputer having a CPU 39 and, for example, a semiconductor memory such as a RAM or a ROM (hereinafter referred to as a memory 41).

Each function of the control unit 33 is realized by the CPU 39 executing a program stored in the non-transitional substantive recording medium. In this example, the memory 41 corresponds to a non-transitional substantive recording medium in which a program is stored. Moreover, when this program is executed, the method corresponding to the program is executed. The control unit 33 may include one microcomputer or a plurality of microcomputers.

As shown in FIG. 3, the control unit 33 includes an in-vehicle device information acquisition unit 43, an abnormality acquisition unit 44, an abnormality determination unit 45, an evaluation result acquisition unit 46, an evaluation result determination unit 47, and a driver designation unit 48. And an output unit 49.

The input unit 34 receives the input operation of the operator of the safe driving diagnosis device 5. The communication unit 35 communicates with the in-vehicle device 3 via the Internet 31. Further, the communication unit 35 communicates with the external device 51 via the Internet 31. Examples of the external device 51 include a computer of a business operator and a computer of an observer. The database 37 can store information.

2. 2. Processing executed by the in-vehicle device 3 The processing executed by the in-vehicle device 3 will be described with reference to FIGS. 4 and 5. This process is started when the operation of the vehicle 7 starts. In step 1 of FIG. 4, the identification information acquisition unit 18 acquires the driver's identification information from the driver's license held by the driver by using the license reading unit 23.

In step 2, the image acquisition unit 12 acquires the driver image using the camera 26.
In step 3, the abnormality detection unit 13 performs a process of detecting an abnormal state of the driver based on the driver image acquired in step 2. Examples of the abnormal state of the driver include a state of inattentive driving, a state of drowsy driving, a state of drowsiness of the driver, a state of the driver's posture being distorted, and a state of involuntary driving.

In step 4, the abnormality detection unit 13 stores the detection result of the abnormal state in the process of step 3 in the database 29.
In step 5, the vehicle information acquisition unit 14 acquires vehicle information using the sensor group 21.

In step 6, the vehicle information acquisition unit 14 stores the vehicle information acquired in step 5 in the database 29.
In step 7, the operation determination unit 19 determines whether or not the operation of the vehicle 7 has been completed. When the operation is completed, the driver inputs to the input unit 25 indicating that the operation has ended (hereinafter referred to as an end input). The operation determination unit 19 determines whether or not the operation of the vehicle 7 has been completed, depending on whether or not the end input has been made to the input unit 25. If it is determined that the operation has ended, this process proceeds to step 8. If it is determined that the operation has not ended, this process proceeds to step 2.

In step 8, the evaluation unit 15 evaluates safe driving based on the vehicle information. The evaluation method is as follows. First, the evaluation unit 15 reads out the vehicle information acquired during the period of the immediately preceding operation from the database 29. The evaluation unit 15 calculates a score for each of the plurality of diagnostic items by analyzing the read vehicle information. As a diagnosis item and a method of calculating a score in the diagnosis item, for example, there are the following.

Diagnostic items for sharp turns: If there is a sharp turn, the score is lower than if there is no sharp turn. The greater the degree of sharp turn, the lower the score.
Diagnostic items related to continuous operation: The longer the continuous operation time, the lower the score.

Diagnostic item for overspeed: If there is overspeed, the score is lower than if there is no overspeed. The greater the degree of overspeed, the lower the score.
Diagnostic items related to rapid acceleration / deceleration: The greater the degree of rapid acceleration / deceleration, the lower the score.

Diagnostic item related to engine speed: When the engine speed is out of the proper range, the score is lower than when it is within the proper range. The more significantly the engine speed deviates from the appropriate range, the lower the score.

Diagnostic item regarding idling speed: When the idling speed is out of the proper range, the score is lower than when it is within the proper range. The greater the degree to which the idling speed deviates from the appropriate range, the lower the score.

Diagnostic items related to slowing down at intersections: If you do not slow down at an intersection, your score will be lower than if you slowed down.
Diagnostic item related to blinker lighting: If the blinker is not turned on when turning left or right, the score is lower than when the blinker is turned on.

The evaluation unit 15 calculates the total score by totaling the scores of each diagnostic item. The overall score corresponds to the evaluation result. Calculating the total score corresponds to making an evaluation of safe driving. The higher the overall score, the better the evaluation result of the evaluation regarding safe driving.

In step 9, the vehicle-mounted device information generation unit 16 generates vehicle-mounted device information. As shown in FIG. 5, the in-vehicle device information 53 includes the total score 55 obtained in step 8, the detection result 57 of the abnormal state, the driver identification information 59 acquired in step 1, and the generation time 61. Information including ,.

The abnormal state detection result 57 is stored in the database 29 in the processes of the step 3 and the step 4 repeatedly executed during the period of one operation. The abnormal state detection result 57 specifies the number of abnormal states detected during one operation period for each type of abnormal state. Examples of the detection result 57 of the abnormal state include the following.

Number of detections of inattentive driving state: A times Number of detections of drowsy driving state: B times Number of detections of driver's drowsiness: C times Number of detections of driver's posture collapse: D times Number of detections: E times A, B, C, D, and E are integers of 0 or more, respectively. The generation time 61 is the time when the in-vehicle device information is generated.

Returning to FIG. 4, in step 10, the transmission unit 17 transmits the in-vehicle device information generated in step 9 to the safe driving diagnostic device 5 using the communication unit 27.
3. 3. Information storage processing executed by the safe driving diagnosis device 5 The in-vehicle device information acquisition unit 43 of the safe driving diagnosis device 5 acquires in-vehicle device information by using the communication unit 35. The in-vehicle device information to be acquired is the one transmitted by the in-vehicle device 3 in the step 10. The in-vehicle device information acquisition unit 43 stores the acquired in-vehicle device information in the database 37.

4. Guidance determination process executed by the safe driving diagnosis device 5 The guidance determination process executed repeatedly by the safe driving diagnosis device 5 at predetermined intervals will be described with reference to FIG. Here, the predetermined interval is one month.

In step 11, the driver designation unit 48 designates the driver to be diagnosed. The operator of the safe driving diagnostic device 5 can input the driver to the input unit 34. The driver designation unit 48 designates the driver input to the input unit 34.

In step 12, the abnormality acquisition unit 44 acquires the degree of abnormality of the driver specified in step 11 during the diagnosis period. The diagnosis period is, for example, the period from one month ago to the present time.

The degree of abnormality during the diagnosis period is the frequency of detection of abnormal conditions during the diagnosis period. The detection frequency is the number of detections per unit time. There are, for example, multiple types of degrees of abnormality during the diagnosis period. The degree of abnormality in the diagnosis period includes, for example, the degree of first to fifth abnormalities in the diagnosis period.

The first degree of abnormality during the diagnosis period is the frequency of detection of the state of inattentive driving during the diagnosis period. The second degree of abnormality during the diagnosis period is the frequency of detection of the state of dozing driving during the diagnosis period. The third degree of abnormality during the diagnosis period is the frequency of detection of drowsiness in the driver during the diagnosis period. The fourth degree of abnormality in the diagnosis period is the detection frequency of the state in which the driver's posture is out of order during the diagnosis period. The fifth degree of abnormality during the diagnosis period is the frequency of detection of the state of involuntary driving during the diagnosis period.

The abnormality acquisition unit 44 acquires the degree of the first to fifth abnormalities in the diagnosis period as follows. The abnormality acquisition unit 44 reads out all the in-vehicle device information stored in the database 37, including the driver identification information 59 specified in step 11, and the generation time 61 is within the diagnosis period. ..

The abnormality acquisition unit 44 calculates the degree of the first to fifth abnormalities in the diagnosis period based on the detection result 57 of the abnormal state included in the read in-vehicle device information.
In step 13, the abnormality determination unit 45 acquires the standard level. The standard degree is the degree of abnormality of the driver specified in step 11 in the standard period. The standard level is set based on the detection result of the abnormal state in the standard period.

The standard period is the period from the time point n months ago to the time point 1 month ago. n is a value greater than 1. n is preferably 6 or more. The standard period is a period that includes a period older than the diagnosis period. The abnormality determination unit 45 acquires a corresponding standard degree for each type of degree of abnormality during the diagnosis period. As the standard level, there are first to fifth standard levels.

The first standard degree corresponds to the degree of the first anomaly during the diagnostic period. The first standard degree is a value obtained by adding F to the detection frequency of the state of inattentive driving in the standard period. F is a constant of 0 or more.
The second standard degree corresponds to the degree of the second anomaly during the diagnostic period. The second standard degree is a value obtained by adding G to the detection frequency of the state of dozing driving in the standard period. G is a constant of 0 or more.

The third standard degree corresponds to the degree of the third anomaly during the diagnostic period. The third standard degree is a value obtained by adding H to the detection frequency of the driver's drowsiness during the standard period. H is a constant of 0 or more.
The fourth standard degree corresponds to the degree of the fourth anomaly during the diagnostic period. The fourth standard degree is a value obtained by adding I to the detection frequency of the state in which the driver's posture is out of order during the standard period. I is a constant of 0 or more.

The fifth standard degree corresponds to the fifth degree of abnormality during the diagnostic period. The fifth standard degree is a value obtained by adding K to the detection frequency of the state of involuntary driving in the standard period. K is a constant of 0 or more.
The abnormality determination unit 45 acquires, for example, the first to fifth standards as follows. The abnormality determination unit 45 reads out all the in-vehicle device information stored in the database 37, including the driver identification information 59 specified in step 11, and the generation time 61 is in the standard period. .. The abnormality determination unit 45 calculates the first to fifth standards based on the detection result 57 of the abnormal state included in the read in-vehicle device information.

In step 14, the abnormality determination unit 45 determines whether or not the degree of the first to fifth abnormalities in the diagnosis period exceeds the corresponding first to fifth standards. That is, the abnormality determination unit 45 determines whether or not each of the following (J1) to (J5) is satisfied.

(J1) The degree of the first abnormality in the diagnosis period exceeds the degree of the first standard.
(J2) The degree of the second abnormality during the diagnosis period exceeds the degree of the second standard.
(J3) The degree of the third abnormality in the diagnosis period exceeds the degree of the third standard.

(J4) The degree of the fourth abnormality in the diagnosis period exceeds the degree of the fourth standard.
(J5) The degree of the fifth abnormality in the diagnosis period exceeds the degree of the fifth standard.

If any one of (J1) to (J5) is satisfied, this process proceeds to step 15. If none of (J1) to (J5) is satisfied, this process proceeds to step 19.
In step 15, the evaluation result acquisition unit 46 includes all the in-vehicle device information stored in the database 37, including the driver identification information 59 specified in step 11, and the generation time 61 is during the diagnosis period. Read in-vehicle device information.

Next, the evaluation result acquisition unit 46 calculates the average value of the total points included in the read in-vehicle device information. The calculated average value is defined as the total score X. The total score X corresponds to the evaluation result of the driver specified in step 11. In addition, the total score X corresponds to the evaluation result regarding safe driving during the diagnosis period.

In step 16, the evaluation result determination unit 47 includes all the in-vehicle device information stored in the database 37, including the driver identification information 59 specified in step 11, and the generation time 61 is in the standard period. Read in-vehicle device information.

Next, the evaluation result determination unit 47 calculates the average value of the total points included in the read in-vehicle device information. The value obtained by subtracting L from the calculated average value is defined as the standard total score Y. L is a constant of 0 or more. The standard total score Y corresponds to the evaluation result of the driver specified in step 11. In addition, the standard total score Y corresponds to the evaluation result regarding safe driving in the standard period. Further, the standard total score Y corresponds to the standard evaluation result.

In step 17, the evaluation result determination unit 47 determines whether or not the total score X is lower than the standard total score Y. The fact that the total score X is lower than the standard total score Y corresponds to the fact that the evaluation result regarding safe driving during the diagnosis period is worse than the standard evaluation result.

If the total score X is lower than the standard total score Y, the process proceeds to step 18. If the total score X is equal to or higher than the standard total score Y, the process proceeds to step 19.
In step 18, the output unit 49 outputs the inadequate guidance determination to the external device 51 using the communication unit 35. The judgment of insufficient guidance means that the degree of abnormality during the diagnosis period is large and the total score X is low.

In step 19, the output unit 49 outputs the guidance sufficient determination to the external device 51 using the communication unit 35. Sufficient guidance means that the degree of abnormality during the diagnosis period is small or the total score X is high.

4. Effects of the Safe Driving Diagnosis System 1 (1A) The Safe Driving Diagnosis System 1 can determine whether or not the degree of abnormality during the diagnosis period exceeds the standard level. That is, the safe driving diagnosis system 1 can diagnose the state of the driver. The safe driving diagnosis system 1 outputs a guidance insufficient judgment or a guidance sufficient judgment based on the result of the diagnosis. The user of the safe driving diagnosis system 1 can know whether or not the driver is sufficiently instructed by the inadequate instruction determination or the sufficient instruction determination.

(1B) The safe driving diagnosis system 1 sets the standard degree based on the degree of abnormality in the standard period of the driver specified in step 11. Therefore, the degree of abnormality in the diagnosis period and the standard degree are the degree of abnormality of the same driver. As a result, the safe driving diagnosis system 1 can more accurately diagnose the state of the driver.

(1C) The safe driving diagnosis system 1 can determine whether or not the total score X is lower than the standard total score Y. That is, the safe driving diagnosis system 1 can evaluate the safe driving. The safe driving diagnosis system 1 outputs a guidance insufficient judgment or a guidance sufficient judgment based on the result of the evaluation regarding safe driving. The user of the safe driving diagnosis system 1 can know whether or not the driver is sufficiently instructed by the inadequate instruction determination or the sufficient instruction determination.

(1D) The safe driving diagnosis system 1 sets a standard total score Y based on the total score in the standard period of the driver specified in step 11. Therefore, the total score X and the standard total score Y are the total points of the same driver. As a result, the safe driving diagnosis system 1 can more accurately evaluate the safe driving.
