The in-vehicle device 3 is mounted on the vehicle 7. The in-vehicle device 3 includes a microcomputer having a CPU 9 and, for example, a semiconductor memory such as a RAM or a ROM (hereinafter referred to as a memory 11). Each function of the in-vehicle device 3 is realized by the CPU 9 executing a program stored in a non-transitional substantive recording medium. In this example, the memory 11 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 sensor group 21 includes a plurality of sensors for acquiring vehicle information. The vehicle information is information indicating the state of the vehicle 7. The contents of vehicle information include speed, steering amount, engine speed, brake operation amount, magnitude of impact applied to vehicle 7, position of vehicle 7, image taken around or inside vehicle 7, and blinker lighting. 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 drive recorder 26 can determine whether or not the recording conditions are satisfied. The recording conditions include, for example, that the acceleration of the vehicle 7 exceeds the threshold value, that the vehicle 7 makes a sharp turn, that the vehicle 7 is impacted, and the like.

When the recording condition is satisfied, the risk of the vehicle 7 is higher than that when the recording condition is not satisfied. Further, when the recording condition is satisfied, it is more likely that the state of the driver of the vehicle 7 is not suitable for driving as compared with the case where the recording condition is not satisfied. Examples of the driver's state unsuitable for driving 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.

When the recording condition is satisfied, the drive recorder 26 performs one recording. Examples of the recording include photographing the surroundings of the vehicle 7 to generate an image, and recording the generated image. Further, as the recording, for example, recording the voice inside or outside the vehicle 7 can be mentioned. Recording is performed for a predetermined period including, for example, a time when the recording conditions are satisfied. The drive recorder 26 outputs one recording signal to the vehicle-mounted device 3 each time recording is performed.

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, a recording frequency calculation unit 44, a recording frequency determination unit 45, an evaluation result acquisition unit 46, an evaluation result determination unit 47, and a decrease determination. It includes a unit 48, a driver designation unit 49, and an output unit 50.

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 17 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 recording number acquisition unit 12 executes a process of acquiring the recording signal output by the drive recorder 26.
In step 3, the recording number acquisition unit 12 performs a process of storing the recorded signal acquired in the process of step 2 in the database 29.

In step 4, the vehicle information acquisition unit 13 acquires vehicle information using the sensor group 21.
In step 5, the vehicle information acquisition unit 13 stores the vehicle information acquired in step 4 in the database 29.

In step 6, the operation determination unit 18 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 18 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 7. If it is determined that the operation has not ended, this process proceeds to step 2.

In step 7, the recording number acquisition unit 12 calculates the number of recorded signals stored in the database 29. The number of recorded signals stored in the database 29 is equal to the number of records made by the drive recorder 26 during the last operation period.

The number of records acquisition unit 12 sets the number of recorded signals stored in the database 29 as the number of records recorded by the drive recorder 26 during the period of the immediately preceding operation. In the following, the number of records made by the drive recorder 26 during one operation is referred to as the number of DR records.

In step 8, the evaluation unit 14 evaluates safe driving based on the vehicle information. The evaluation method is as follows. First, the evaluation unit 14 reads out the vehicle information acquired during the period of the immediately preceding operation from the database 29. The evaluation unit 14 analyzes the read vehicle information to calculate points for each of the plurality of diagnostic items. 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 14 totals the scores of each diagnostic item to calculate the total score. 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 15 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 number of DR records 57 calculated in step 7, and the driver identification information 59 acquired in step 1. This is information including the generation time 61. 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 16 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 FIGS. 6 and 7. Here, the predetermined interval is one month.

In step 11, the driver designation unit 49 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 49 designates the driver input to the input unit 34.

In step 12, the recording frequency calculation unit 44 calculates the recording frequency (hereinafter referred to as the diagnostic recording frequency) in the diagnosis period for the driver specified in step 11. The diagnosis period is, for example, the period from one month ago to the present time. The recording frequency is the number of recordings of the drive recorder 26 per operation.

The recording frequency calculation unit 44 calculates the diagnostic recording frequency as follows. The recording frequency calculation unit 44 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 within the diagnosis period. read out. The recording frequency calculation unit 44 uses the average value of the number of DR recordings 57 included in the read in-vehicle device information as the diagnostic recording frequency.

In step 13, the recording frequency determination unit 45 calculates the recording frequency (hereinafter referred to as the standard recording frequency) in the standard period for the driver specified in step 11. The standard period is, for example, a period from a time point n months ago to a 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 recording frequency determination unit 45 calculates the standard recording frequency as follows. The recording frequency determination unit 45 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 within the standard period. read out.

The recording frequency calculation unit 44 calculates the average value of the number of DR recordings 57 included in the read in-vehicle device information. The recording frequency calculation unit 44 uses a value obtained by adding A to the average value as the standard recording frequency. A is a constant of 0 or more. The standard recording frequency calculated in this way is a standard recording frequency set based on the recording frequency in the standard period of the driver specified in step 11.

In step 14, the recording frequency determination unit 45 determines whether or not the diagnostic recording frequency exceeds the standard recording frequency. If the diagnostic recording frequency exceeds the standard recording frequency, this process proceeds to step 15. If the diagnostic recording frequency is less than or equal to the standard recording frequency, the process proceeds to step 20.

In step 15, the reduction determination unit 48 determines whether or not the recording frequency of the driver specified in step 11 decreases with the passage of time. The reduction determination unit 48 performs the following processing.

The reduction determination unit 48 includes all the vehicle-mounted 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 or the standard period. Read the machine information. The reduction determination unit 48 calculates the recording frequency for each of the read in-vehicle device information. The recording frequency for any in-vehicle device information is equal to the number of DR recordings 57 included in the same in-vehicle device information.

As shown in FIG. 7, the reduction determination unit 48 plots the recording frequency calculated as described above and the generation time 61 included in the corresponding in-vehicle device information on a graph. In this graph, the decrease determination unit 48 determines whether or not the recording frequency decreases with the passage of time. If it is determined that the recording frequency decreases with the passage of time, this process proceeds to step 16. If it is determined that the recording frequency cannot be said to decrease with the passage of time, this process proceeds to step 19.

In step 16, 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 55 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 17, 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 55 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 18, 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 19. If the total score X is equal to or greater than the standard total score Y, the process proceeds to step 20.
In step 19, the output unit 50 outputs the inadequate guidance determination to the external device 51 using the communication unit 35. Judgment of insufficient guidance basically means that the frequency of diagnostic records is high. However, even if the diagnosis recording frequency is high, if the recording frequency decreases with the passage of time and the total score X is high, the judgment of insufficient guidance is not output.

In step 20, the output unit 50 outputs the guidance sufficient determination to the external device 51 using the communication unit 35. Sufficient guidance judgment basically means that the frequency of diagnostic records is low. However, even if the diagnosis recording frequency is high, if the recording frequency decreases with the passage of time and the total score X is high, a sufficient guidance judgment is output.

4. Effects of the Safe Driving Diagnosis System 1 (1A) The Safe Driving Diagnosis System 1 can determine whether or not the diagnostic recording frequency exceeds the standard recording frequency.

(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 55 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.

(1E) The safe driving diagnosis system 1 determines whether or not the recording frequency of the driver specified in step 11 decreases with the passage of time. The decrease in recording frequency over time indicates that the driver's condition is improving. The safe driving diagnosis system 1 can determine whether or not the driver's condition is improved.
