The display control unit 55 generates a moving image Em in the evaluation period t1 based on the evaluation period image data. The graph Eg, the table Et, and the moving image Em in the evaluation period t1 constitute the detailed display data E1 in the evaluation period t1.

  Further, the display control unit 55 synchronizes temporally the graph Eg, the table Et, and the moving image Em included in the detailed display data E. Specifically, the display control unit 55 causes the display 44 to simultaneously display measurement values and image data associated with the same time information.

  Even when the display control unit 55 generates a plurality of detailed display data E1 and E2, the display control unit 55 does not display the detailed display data E1 and E2 together on the display 44 (see FIG. 7).

  In FIG. 7, the display 44 further displays a basic display unit F, an evaluation position display unit G, an image control unit H, a switching button unit I, and a voice button unit J.

  The basic display unit F shows vehicle identification information and evaluation results related to the detailed display data E. The evaluation position display part G shows an evaluation position related to the detailed display data E. The image control unit H, the switching button unit I, and the voice button J each display buttons operated by the instructor. These units F to J are also generated by the display control unit 55.

  When the image control unit H is tapped by the instructor, the touch panel 45 receives various image control commands related to the display of the moving image Em. The image control command is sent from the touch panel 45 to the display control unit 55. The display control unit 55 controls the display of the moving image Em such as playback and stop based on the image control command.

  When the switching button I is tapped by the instructor, the touch panel 45 receives a switching command related to display on the display 44. The switching command is sent from the touch panel 45 to the display control unit 55. The display control unit 55 causes the display 44 to display the result display data A and the like instead of the detailed display data E and the like based on the switching command. For example, the display on the display 44 is switched from the display illustrated in FIG. 7 to the display illustrated in FIG.

  As shown in FIG. 6, when the display 44 displays the result display data A, the lines b1 and b2 indicating the evaluation positions in the result display data A also serve as switching buttons. When the line b is tapped, the touch panel 45 receives a switching command and sends the switching command to the display control unit 55. The display control unit 55 switches the display on the display 44 based on the switching command. As a result, the display 44 displays the detailed display data E at the tapped evaluation position instead of the result display data A. The touch panel 45 is an example of a switching command input unit in the present invention.

Specifically, when the instructor operates the voice button part C or the voice button part J (see FIGS. 6 and 7), the touch panel 45 receives an ON command. The ON command is sent from the touch panel 45 to the notification control unit 56. The notification control unit 56 turns on the microphone 46 based on the ON command. After the microphone 46 is turned on, the instructor inputs message information to the microphone 46. The microphone 46 is an example of a message information input unit in the present invention.

  The notification control unit 56 controls the operations of the microphone 46 and the transmission unit 57. The notification control unit 56 further determines at least one vehicle device 5 as a message information notification destination. The process of determining the notification destination depends on the case where the voice button part C displayed together with the result display data A is operated and the case where the voice button part J displayed together with the detailed display data E is operated. Different.

  When the voice button part C is operated, the instructor operates the designation button part D (see FIG. 6) displayed on the display 44 together with the voice button part C. Thereby, the touch panel 45 accepts a designation command for designating a notification destination. The designation command is sent from the touch panel 45 to the notification control unit 56. The notification control unit 56 determines the vehicle device 5 designated by the designation command as a notification destination.

  When the voice button unit J is operated, the notification control unit 56 specifies the motorcycle 3 related to the detailed display data E, and determines the vehicle device 5 provided in the specified motorcycle 3 as a notification destination.

  The transmission unit 57 transmits message information to the vehicle device 5 determined as the notification destination. The transmitted message information is received by the vehicle device 5 that is the notification destination and is output by the speaker 38.

  The evaluation period determination unit 52 determines an evaluation period based on the measurement data. Hereinafter, the process which determines an evaluation period is illustrated.

The evaluation period determination unit 52 acquires measurement data related to the yaw rate from the data storage unit 51. The evaluation period determination unit 52 acquires the lower limit value _Xt and the minimum duration Y _min from the evaluation period condition storage unit 58. The lower limit _Xt and the minimum duration Y _min are examples of evaluation period condition information. The evaluation period determining unit 52 determines an evaluation period period absolute value of the yaw rate is not less than the lower limit value X _t over a minimum duration Y _min. The determined evaluation period corresponds to a period during which the motorcycle 3 is turning.

  The evaluation unit 53 includes a component separation unit 61, a vehicle stability characteristic evaluation unit 62, a turning characteristic determination unit 63, and a comprehensive evaluation unit 64.

  The component separation unit 61 extracts a low frequency component and a high frequency component of the evaluation period measurement data. Below, the process which extracts the low frequency component and high frequency component of the roll rate in an evaluation period is illustrated.

  The component separation unit 61 reads roll rate measurement data from the data storage unit 51. The component separation unit 61 extracts evaluation period measurement data from the measurement data based on the evaluation period. The component separation unit 61 reads out the low pass filter and the band pass filter from the evaluation criterion storage unit 59. The low pass filter and the band pass filter are examples of filters. The component separation unit 61 removes high frequency components higher than a predetermined threshold frequency Fc1 from the evaluation period measurement data using a low-pass filter. Thereby, the component separation unit 61 obtains a low frequency component of the roll rate in the evaluation period. The component separation unit 61 uses a bandpass filter to remove a low frequency component having a threshold frequency Fc1 or less and a noise component having a predetermined threshold frequency Fc2 (Fc2> Fc1) or more from the evaluation period measurement data. From this, the component separation part 61 obtains the high frequency component of the roll rate in the evaluation period.

  The vehicle stability characteristic evaluation unit 62 evaluates the driving skill from the viewpoint of vehicle stability characteristics based on the evaluation period measurement data. Hereinafter, the process of the vehicle stability characteristic evaluation unit 62 will be specifically exemplified.

Here, the ratio between the integral value of the absolute value of the low frequency component and the integral value of the absolute value of the high frequency component is defined as a stability characteristic index S. The vehicle stability characteristic evaluation unit 62 calculates a stability characteristic index S _yaw related to the _yaw rate, a stability characteristic index S _roll related to the roll rate, and a stability characteristic index S _pitch related to the pitch rate. Further, the vehicle stability characteristic evaluation unit 62 calculates a weighted linear sum (hereinafter referred to as “vehicle stability characteristic score S _v ”) of the stability characteristic indexes S _yaw , S _roll, S _pitch .

Stable characteristic indicator S _yaw, S _roll, such as a function for calculating the S _pitch and vehicle stability properties score S _v is included in the vehicle stability characterization information. The vehicle stability characteristic evaluation unit 62 performs the above-described processing using the vehicle stability characteristic evaluation information read from the evaluation criterion storage unit 59.

  The turning characteristic evaluation unit 63 evaluates the driving skill from the viewpoint of turning characteristics based on the evaluation period measurement data and the evaluation period position data. Hereinafter, the process of the turning characteristic evaluation unit 63 will be specifically exemplified.

The turning characteristic evaluation unit 63 acquires the low frequency components of the roll angle and the pitch angle in the evaluation period from the component separation unit 61. The turning characteristic evaluation unit 63 calculates an integral value of the absolute value of the low frequency component of the roll angle (hereinafter referred to as “turning characteristic index T _roll ”). Similarly, the turning characteristic evaluation unit 63 calculates an integral value (hereinafter referred to as “turning characteristic index T _pitch ”) of the absolute value of the low frequency component of the pitch rate. The turning characteristic evaluation unit 63 extracts evaluation period position data based on the evaluation period and position data. The turning characteristic evaluation unit 63 calculates the average vehicle speed T _speed during the evaluation period based on the evaluation period position data. The turning characteristic evaluation unit 63 further calculates a weighted linear sum (hereinafter referred to as “turning characteristic score T _v ”) of the turning characteristic indexes T _roll and T _pitch and the average vehicle speed T _speed .

Turning characteristic index T _roll, T _pitch, average speed T _speed, such as a function for calculating a turning characteristic score T _v is included in the turning characteristic evaluation information. Note that the turning characteristic evaluation information and the vehicle stability characteristic evaluation information define different evaluation criteria. The turning characteristic evaluation unit 63 performs the above-described processing using the turning characteristic evaluation information read from the evaluation reference storage unit 59.

Comprehensive evaluation unit 64, based on the vehicle stability characteristics scores S _v and turning characteristic score T _v, to comprehensively evaluate the driving skill. Hereinafter, the process of the comprehensive evaluation unit 64 will be specifically exemplified.

Comprehensive evaluation unit 64, the weighted linear sum of the vehicle stability characteristics score S _v and turning characteristic score T _v (hereinafter referred to as "overall performance score U") is calculated. The comprehensive evaluation unit 64 compares the comprehensive characteristic score U with a threshold value. As a result, when the total characteristic score U is higher than the threshold value, the comprehensive evaluation unit 64 determines the evaluation result as “good evaluation result”. Otherwise, the comprehensive evaluation unit 64 determines the evaluation result as “bad evaluation result”.

  A function for calculating the total characteristic score U, a threshold value for classifying the evaluation result according to the total characteristic score U, and the like are included in the total evaluation information. The comprehensive evaluation unit 64 performs the above-described processing using the comprehensive evaluation information read from the evaluation reference storage unit 59.

4). Operation of the Learning Support System 1 The operation of the learning support system 1 in this embodiment will be described. In the following description, it is assumed that the student M is riding the motorcycle 3.

  FIG. 10 is a flowchart showing an operation of transmitting data.

  The GPS receiver 33 detects the time and the position of the motorcycle 3 (step S1). The vehicle attitude angle sensor 34 measures the attitude angle of the motorcycle 3 (step S2). The camera 35 performs shooting (step S3).

  CPU31 reads the detection result of the GPS receiving part 33, and determines whether the detection of the position and time was successful (step S4). If it is determined to be successful, the process proceeds to steps S5, S6, and S8. Otherwise, the process returns to step S1.

  CPU31 produces | generates position data (step S5). The CPU 31 reads the measurement result of the vehicle attitude angle sensor 34 and determines whether or not the measurement is successful (step S6). When it determines with success, CPU31 produces | generates measurement data (step S7). Otherwise, skip step S7 and proceed to step S10. The CPU 31 reads the photographing result of the camera 35 and determines whether or not the photographing is successful (step S8). If it is determined to be successful, the CPU 31 generates image data (step S9). Otherwise, skip step S9 and proceed to step S10.

  The communication unit 36 transmits the generated various data (step S10). The data to be transmitted always includes position data. Then, the process returns to step S1.

  As described above, when the position and time are successfully detected, the position data is transmitted at any time. At this time, when measurement data and image data are generated, they are transmitted together.

  FIG. 11 is a flowchart showing an operation for displaying display data.

  The receiving unit 50 receives position data, measurement data, and image data (step S11).

  The display control unit 55 specifies a travel locus based on the position data (step S12). The evaluation period determination unit 52 performs a process of determining the evaluation period based on the measurement data (step S13). When the evaluation period is determined as a result of step S13, the process proceeds to steps S14 and S15. Otherwise, skip steps S14 and S15 and proceed to steps S16 and S17.

  The display control unit 55 specifies the evaluation position based on the evaluation period and the position data (step S14). The evaluation unit 53 performs an evaluation process based on the evaluation period, measurement data, and position data, and acquires an evaluation result (step S15).

  The display control unit 55 generates result display data A based on the travel locus, the evaluation position, and the evaluation result (step S16). The display control unit 55 generates detailed display data E based on the evaluation period, measurement data, and image data (step S17). However, if the evaluation period is not determined as a result of step S13, the display control unit 55 updates the traveling locus of the result display data A based on the traveling locus (step 16). In this case, the detailed display data E is not generated (step S17).

  The display 44 displays the display data A and E generated in steps S16 and S17 (step S18). In step S18, the display 44 displays either the result display data A or the detailed display data E according to the operation of the instructor.

  When displaying the result display data A, the display 44 displays all the result display data A generated in step S16 side by side. The display 44 displays the legend part B, the voice button part C, and the designation button part D together with the result display data A.

  When displaying the detailed display data E, the display 44 displays any one of the detailed display data E generated in step S17. Further, the display 44 displays a basic display part F, an evaluation position display part G, an image control part H, a switching button part I, and a voice button part J together with the detailed display data E.

  FIG. 12 is a flowchart showing an operation of notifying message information from the instructor device 7 to the vehicle device 5. In FIG. 12, steps S21 to S23 are operations of the instructor apparatus 7, and steps S24 and S25 are operations of the vehicle apparatus 5.

  In response to the operation of the voice buttons C and J by the instructor, the notification controller 56 turns the microphone 46 on. The microphone 46 acquires the instructor's utterance as message information (step S21). The notification control unit 56 specifies the vehicle device 5 that is the notification destination in response to the operation of the designation button unit D by the instructor or the control of the display 44 by the display control unit 55 (step S22). The transmission unit 57 transmits the message information to the vehicular device 5 that is the notification destination (step S23).

  The communication part 36 of the apparatus 5 for vehicles receives message information (step S24). The speaker 38 of the vehicle device 5 outputs message information (step S25).

  As described above, according to the first embodiment, the instructor apparatus 7 includes the display control unit 55 that generates the result display data A and the display 44 that displays the result display data A. The result display data A shows the evaluation position and the evaluation result in the same evaluation period in association with each other. Therefore, the instructor can suitably confirm the position where the student M has driven the motorcycle 3 and the evaluation result regarding the driving skill at the position. Therefore, the instructor can appropriately instruct the student M.

  In particular, evaluation position and evaluation result information is held on the display 44 and can be looked back. That is, the instructor can look back at the evaluation position and the evaluation result at any time by simply looking at the display 44. In this respect, the evaluation position and the evaluation result indicated by the result display data A are greatly different from the information indicated by the normal moving image and sound. For this reason, even if the instructor does not always monitor the display 44, the instructor can confirm the evaluation position and the evaluation result at an arbitrary timing, thereby confirming the evaluation position and the evaluation result that should not be overlooked without omission. Therefore, the instructor can appropriately confirm the driving operation of the student M.

  Furthermore, since it is not always necessary to continuously monitor the display 44, the instructor can carry out the lessons with ease. For example, it is possible to look directly at the state where the student M is driving the motorcycle 3 while keeping an eye on the display 44. According to this, the instructor can grasp the driving operation of the student M in more detail.

  In the result display data A, the display control unit 55 changes the manner in which the evaluation position is displayed according to the evaluation result. Therefore, not only the evaluation position but also the evaluation result at the evaluation position can be suitably displayed. Specifically, the display control unit 55 changes the thickness of the line indicating the evaluation position according to the evaluation result. According to this, both the evaluation position and the evaluation result can be shown by one line.

  In the result display data A, the display control unit 55 emphasizes the bad evaluation result rather than the good evaluation result. Thereby, the instructor can confirm the bad evaluation result more easily.

  In the result display data A, the display control unit 55 indicates the evaluation position by a line drawn on the route map a. Therefore, the instructor can confirm the relative positional relationship between the runway and the evaluation position.

  The display control unit 55 further indicates a travel locus in the result display data A. Therefore, the instructor can confirm the traveling locus.

  The display control unit 55 causes the display 44 to display a plurality of result display data A in a list. Therefore, the instructor can simultaneously confirm the evaluation results regarding the driving skills of a plurality of students M.

  The display control unit 55 generates detailed display data E, and the display 44 displays the detailed display data E. The detailed display data E indicates evaluation period measurement data. Therefore, the state of the motorcycle 3 at the evaluation position can be confirmed in detail. Specifically, the detailed display data E includes a graph Eg indicating the evaluation period measurement data. Therefore, the instructor can easily confirm the temporal change in the measured value during the evaluation period. The detailed display data E includes a table Et indicating the evaluation period measurement data. Therefore, the instructor can easily confirm the measurement value (instantaneous value) included in the evaluation period measurement data.

  Detailed display data E indicates evaluation period image data. Therefore, the instructor can see the state of the motorcycle 3 at the evaluation position. Specifically, the detailed display data E includes a moving image Em indicating evaluation period image data. Therefore, the state of the motorcycle 3 at the evaluation position can be seen in detail.

  The display control unit 55 displays the graph Eg, the table Et, and the moving image Em in synchronization. Therefore, the state and state of the motorcycle 3 at the evaluation position can be confirmed in more detail.

  The touch panel 45 receives a switching command by an operation by an instructor. The display control unit 55 switches the display on the display 44 between the result display data A and the detailed display data E based on the switching command. Thereby, the instructor can promptly confirm the result display data A and the detailed display data E, respectively. In particular, the line b indicating the evaluation position in the result display data A also serves as a switching button. Thereby, the instructor can easily select the detailed display data E at an arbitrary evaluation position.

  Since the instructor device 7 includes the receiving unit 50, the position data of the motorcycle 3 can be received at a position away from the motorcycle 3. Therefore, the instructor can use the instructor device 7 at a position away from the motorcycle 3.

  Since the instructor device 7 includes the microphone 46, the instructor can promptly input message information. Since the instructor apparatus 7 includes the transmission unit 57, the instructor apparatus 7 can give message information to the student M. As a result, the driving operation of the student M can be improved efficiently.

  The display control unit 55 displays the designation button part D on the display 44 together with the result display data A, the touch panel 45 accepts a designation command according to the operation of the instructor, and the notification control unit 56 selects a notification destination based on the designation command. decide. Thereby, the instructor can easily select the student M who notifies the message information. When the voice button J is operated while the detailed display data E is being displayed, the notification control unit 56 automatically determines the notification destination based on the control of the display 44 by the display control unit 55. Thereby, the operation by the instructor is reduced, and the instructor can notify the message information more promptly.

  Since the evaluation unit 53 acquires the evaluation result based on the evaluation period, the measurement data, and the position data, the evaluation result is objective and quantitative. Therefore, the instructor can grasp the driving skill of the student M objectively and quantitatively. In addition, the instructor can properly grasp the transition of the driving skill of the student M. That is, it is possible to properly grasp the effect of guidance by the instructor.

  The instructor device 7 includes the evaluation period determination unit 52 and the evaluation unit 53. Therefore, it is possible to prevent the process for determining the evaluation period and the evaluation process from varying among the plurality of motorcycles 3.

  Since the position data, the measurement data, and the image data each include time information, the position information, the measurement value, and the image information can be suitably synchronized. Further, since the position data, measurement data, and image data each include vehicle identification information, various data can be associated with each motorcycle 3. Therefore, various data relating to the plurality of motorcycles 3 can be suitably managed by the single instructor device 7.

  Further, when the detection by the GPS receiver 33 is successful, the vehicle device 5 generates and transmits position data even if the measurement by the vehicle attitude angle sensor 34 and the photographing by the camera 35 are not successful. . Thus, the instructor device 7 can update the traveling locus of the motorcycle 3 in substantially real time.

  Since the vehicular device 5 includes the speaker 38, message information can be suitably presented to the student M.

  The learning support system 1 according to the second embodiment includes a vehicle device 5 and a teacher device 7. Since the hardware configuration of the vehicle device 5 and the instructor device 7 is the same as that of the first embodiment, the description thereof is omitted. Hereinafter, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 13 is a block diagram illustrating the functional configuration of the learning support system 1 according to the second embodiment. FIG. 13 shows a functional configuration particularly related to the display of the instructor apparatus 7. As illustrated, in the second embodiment, the vehicle device 5 calculates an evaluation period and an evaluation result.

  In addition to the data generation unit 71, the vehicle device 5 includes a data storage unit 72, an evaluation period determination unit 73, and an evaluation unit 74. These units 71, 73, and 74 are functions realized by the CPU 31 executing a program. The data storage unit 72 is realized by the storage unit 32.

  The data generation unit 71 generates position data, measurement data, and image data. The data storage unit 72 stores position data, measurement data, and image data. The evaluation period determination unit 73 and the evaluation unit 74 perform the same processing as the evaluation period determination unit 52 and the evaluation unit 53 of the first embodiment, respectively. The communication unit 36 transmits position data, measurement data, image data, an evaluation period, and an evaluation result.

  The instructor device 7 includes an evaluation result storage unit 76. The evaluation result storage unit 76 is realized by the storage unit 42. The evaluation result storage unit 76 accumulates the evaluation period and the evaluation result. The display control unit 55 performs processing using the evaluation period and the evaluation result stored in the evaluation result storage unit 76 in addition to the various data stored in the data storage unit 51.

  According to the second embodiment configured as described above, the same effects as the first embodiment are obtained.

  In addition, since the instructor apparatus 7 does not include the evaluation period determination unit 52 and the evaluation unit 53 described in the first embodiment, the processing load on the CPU 41 of the instructor apparatus 7 can be reduced.

  The present invention is not limited to the above embodiment, and can be modified as follows.

  (1) In the above-described embodiment, the evaluation position and the evaluation result indicated by the result display data A may be changed so as to be limited to a specific evaluation position and the evaluation result. For example, the result display data A may indicate an evaluation position and an evaluation result within a predetermined time. For example, the result display data A may indicate an evaluation position and an evaluation result within a predetermined travel distance.

  Refer to FIG. FIG. 14 is a block diagram illustrating a functional configuration of the learning support system 1 according to a modified embodiment. The instructor device 7 includes a monitoring condition storage unit 77. The monitoring condition storage unit 77 stores monitoring condition information.

  The display control unit 55 extracts an evaluation position and an evaluation result that match the monitoring condition information, and generates display data A based on the extracted evaluation position and the evaluation result. The display data A shows the extracted evaluation position and evaluation result, and does not show the evaluation position and evaluation result that were not extracted. Therefore, the instructor can efficiently check the evaluation position and the evaluation result that match the monitoring condition information.

  Here, the monitoring condition information defines, for example, at least one of a monitoring time (for example, 2 minutes) and a monitoring distance.

  When the monitoring condition information defines the monitoring time, the display control unit 55 specifies a period from the reference time to a time that is back by the monitoring time as the monitoring period. The display control unit 55 extracts the evaluation period within the monitoring period from the already determined evaluation period. The display control unit 55 specifies the evaluation position and the evaluation result in the extracted evaluation period. The display control unit 55 generates result display data A indicating the specified evaluation position and evaluation result. Here, the reference time is, for example, the time indicated by the latest time information included in the position data. The reference time is, for example, a time when the display control unit 55 performs processing for generating the result display data A.

  When the monitoring condition information defines the monitoring distance, the display control unit 55 identifies a range (traveling locus) in which the traveling distance of the motorcycle 3 up to the reference position is equal to or less than the monitoring distance as a monitoring section. The display control unit 55 extracts the evaluation position included in the monitoring section from the already specified evaluation position. The display control unit 55 identifies an evaluation result related to the extracted evaluation position. The display control unit 55 generates result display data A indicating the extracted evaluation position and the specified evaluation result. Here, the reference position is, for example, a position indicated by position information associated with the latest time information.

  (2) In each embodiment described above, the vehicle attitude angle sensor 34 is exemplified as the vehicle state measurement unit, but the present invention is not limited to this. The vehicle state may be measured by various sensors. Here, the vehicle state measuring unit may be a sensor that measures the behavior of the vehicle (for example, the vehicle speed) and the state of the engine 22 (for example, the engine speed). Further, the vehicle state measuring unit may be a sensor that detects an operation (for example, a clutch operation) by the student M. Furthermore, the vehicle device 5 may include a driver state measuring unit that measures the state of the student M (for example, the angle of the head) in addition to the vehicle state measuring unit. A specific example will be described below.

The front wheel suspension stroke sensor 86 measures the amount of expansion / contraction of the front fork 15. The rear wheel suspension stroke sensor 87 measures the amount of expansion and contraction of the shock absorber 94. The shock absorber 94 expands and contracts according to the swing of the swing arm 27 to absorb and attenuate the impact. The clutch operation sensor 88 measures the operation of the clutch lever. The engine speed sensor 89 measures the speed of the engine 22. The gear position sensor 90 detects the shift position. The throttle opening sensor 91 measures the throttle opening.

The interface 98 is electrically connected to the sensors 81 to 92 and the external speaker 96 by wire or wirelessly. The measured values of the sensors 81 to 92 are respectively input to the control unit 97 through the interface 98. The control unit 97 causes the external speaker 96 to output sound via the interface 98.

  The CPU 31 (data generation unit 71) generates measurement data regarding the state of the motorcycle 3 at each time and measurement data regarding the state of the student M at each time. Each measurement data includes a measurement value acquired by each sensor 81 to 92 and time information associated with the measurement value. The communication unit 36 transmits measurement data together with position data.

  The vehicular apparatus 5 configured as described above supplies various measurement data to the instructor apparatus 7. The display control unit 55 generates detailed display data E based on various measurement data, and the display 44 displays the detailed display data E including various measurement data.
