  By the way, in recent years, environmental issues have been greatly taken up, and the importance of fuel-saving driving has been screamed as part of that.

  However, none of the conventional driving training devices including Patent Documents 1 and 2 can effectively perform fuel-saving driving training.

  The present invention has been made in consideration of such problems, and an object of the present invention is to provide a driving training apparatus capable of effectively training fuel-saving driving.

The driving training device according to the present invention trains driving ability required when driving a vehicle using a simulated road environment displayed on a monitor screen, and the driving training device includes: A training control unit that displays a simulated road environment seen from a simulated vehicle on the monitor screen as a moving image, a vehicle operation command input unit that includes a steering wheel operating tool, an accelerator operating tool, and a brake operating tool that control the operation of the simulated vehicle; The training control unit includes a simulated driving process for causing a trainee to perform a simulated driving using a simulated course provided with an evaluation target section for evaluating fuel-saving driving, and a moving image of the simulated driving on the monitor screen. in running and reproduction processing for reproducing, in the above simulated driving processing, storing an input for at least the evaluation interval for the vehicle operation command input unit, in the reproduction process, the When the reproduction of the simulated driving the valence target section, in reproduction of the previous SL simulated driving, the accelerator operation member so as to correspond to the reproduced scene operation amount and a continuous display and fuel-saving driving of the vehicle speed of the simulated vehicle On the monitor screen, a display indicating that the name and data for evaluating the fuel-saving driving are being measured is displayed on the monitor screen, and information on the fuel-saving driving in the evaluation target section and evaluation of the fuel-saving driving for the simulated driving are performed. The result is output as video or audio for each evaluation target section .

  According to the present invention, while reproducing the trainee's simulated driving, the fuel-saving driving information related to the simulated driving and the fuel-saving driving evaluation of the simulated driving are output in video or voice. Therefore, the trainee can check the fuel-saving driving information related to the simulated driving and the evaluation of the simulated driving while reviewing the simulated driving. Therefore, the trainee can grasp the self-improvement point regarding the fuel-saving driving with a real feeling. Further, when reproducing the simulated driving, the operation amount of the accelerator operating tool and the vehicle speed of the simulated vehicle are displayed on the monitor screen. For this reason, since the amount of operation of the accelerator operating tool and the vehicle speed of the simulated vehicle can be visually confirmed, it is possible to convey the evaluation of the simulated driving related to fuel saving to the trainee in a convincing manner. Therefore, it is possible to effectively train fuel-saving driving.

The said training control part may evaluate the said simulation driving | operation using the change of the operation amount of the said accelerator operating tool, or the operation timing of stepping on / off as a parameter | index. As a result, the simulated driving is evaluated based on the change in the amount of operation of the accelerator operating tool or the on / off operation timing of the depression , so it is possible to easily evaluate the degree of fuel-saving driving by setting the threshold and range for evaluation. It becomes. In addition, it is possible to perform driving training on the operation of the accelerator operating tool, which is the basis of fuel consumption, from the viewpoint of the operation for suppressing fuel consumption. For this reason, if acceleration / deceleration driving and cruise driving by the operation of the accelerator operating tool are targeted for evaluation, it can be expected to greatly contribute to the spread of fuel-saving driving for these driving.

  The training control unit executes a re-simulation operation process that causes the trainee to perform the simulation operation again, and the transition of the operation amount of the accelerator operation tool in the simulation operation process and the re-simulation operation process is ideal. It may be displayed on the monitor screen so as to overlap with a change in the operation amount. Thereby, it becomes possible to compare the operation amount in the first simulated operation with the operation amount in the second simulated operation on the basis of the ideal operation amount of the accelerator operation tool. Therefore, it is possible to visually confirm the improvement status of the second simulated operation compared to the first simulated operation and the waste situation of the fuel consumption in the first and second simulated operations.

  According to the present invention, while reproducing the trainee's simulated driving, the fuel-saving driving information related to the simulated driving and the fuel-saving driving evaluation of the simulated driving are output in video or voice. Therefore, the trainee can check the fuel-saving driving information related to the simulated driving and the evaluation of the simulated driving while reviewing the simulated driving. Therefore, the trainee can grasp the self-improvement point regarding the fuel-saving driving with a real feeling. Further, when reproducing the simulated driving, the operation amount of the accelerator operating tool and the vehicle speed of the simulated vehicle are displayed on the monitor screen. For this reason, since the amount of operation of the accelerator operating tool and the vehicle speed of the simulated vehicle can be visually confirmed, it is possible to convey the evaluation of the simulated driving related to fuel saving to the trainee in a convincing manner. Therefore, it is possible to effectively train fuel-saving driving.

The trainee P1 can drive the simulated vehicle Vs on the monitor 18 by performing input to the input unit 14 in accordance with the driving simulation screen (details will be described later).

  Next, the process of the driving training apparatus 10 of this embodiment is demonstrated. The processing described below is performed by executing software stored in a memory (not shown) by a CPU (Central Processing Unit) (not shown) of the computer main body 22.

  The driving training device 10 includes a driving mode, a pair mode, a kids mode, and an ecology mode as driving simulation training modes. The drive mode is a training mode for the purpose of improving the driving ability (actual ability and driving knowledge) of the driver.

  When the power of the computer main body 22 is turned on in step S1, the computer main body 22 displays a user menu (not shown) on the monitor 18 in step S2 after the startup process, and in step S3, the training mode is displayed. Select. The user menu shows options for each of the above-described training modes (drive mode, pair mode, kids mode, and ecology mode). Each option has a frame of a training mode name and a symbol image (for example, pair mode is an image of two parents and children, kids mode is an image of multiple children, and ecology mode is an image of the earth). It is displayed in the inside. The currently selected training mode is enlarged and displayed surrounded by a thick frame, and an explanation of the training mode is displayed near the frame. In the present embodiment, the drive mode is the default setting.

  In addition, in the above user menu, a message “Turn the handle to select the item to play. Once selected, press the A button or press the accelerator pedal to determine.” Is also displayed. . As shown in this message, the training mode is selected by turning the handle 24 and pressing the A button (the first button 32a of the input unit 14) or the accelerator pedal 28. That is, in step S <b> 3, when the handle 24 is turned, the computer main body 22 switches the training mode selected on the monitor 18. Further, it is monitored whether the A button (the first button 32a of the input unit 14) is pressed and whether the accelerator pedal 28 is depressed (that is, whether the training mode is selected), and either one is performed. It is determined that the training mode at the time is selected.

  When the training mode is selected in step S3, the computer main body 22 executes the selected training mode in step S4.

  FIG. 4 shows a flowchart when the ecology mode is selected as the training mode (an example of S4 in FIG. 3). When the ecology mode is selected in step S3 of FIG. 3, in step S11, the computer main body 22 executes an opening effect process for the ecology mode. Specifically, the options of the experience mode (ecology drive course) and the certification mode (ecology certification course) in the ecology mode are displayed on the monitor 18 together with a character (not shown) (the experience mode is a default setting). is there.). The experience mode is a mode for learning fuel-saving driving while reproducing simulated driving after simulated driving. The verification mode is a mode for evaluating the degree of fuel-saving driving through simulated driving.

  Further, in accordance with the above display, following the word “Welcome to ecology mode!” As the voice of the character, explanation is given by voice that environmentally friendly driving leads to safe driving.

  In step S12, the computer main body 22 monitors whether or not the first button 32a of the input unit 14 is pressed and whether or not the accelerator pedal 28 is depressed, and is selected when any one of the operations is performed. The option is executed in the subsequent processing. For example, when the first button 32a is pressed or the accelerator pedal 28 is depressed with the experience mode selected, the experience mode is selected. The test mode is selected in the same way.

  In subsequent step S <b> 13, the computer main body 22 provides an operation explanation. Specifically, the image of the input unit 14 stored in a memory (not shown) is displayed on the monitor 18, and the positions of the select lever 26, the accelerator pedal 28 and the brake pedal 30, It is displayed that the 1 button 32a is for lighting operation, the second button 32b is for left turn signal operation, the third button 32c is for right turn signal operation, and the fourth button 32d is for wiper operation.

  In subsequent steps S14 to S20, the computer main body 22 performs driving training (driving simulation). Hereinafter, a case where the experience mode (ecology drive course) is selected will be described.

  In step S <b> 14, the computer main body 22 performs a simulated driving process in which the trainee P <b> 1 drives the simulated vehicle Vs using the input unit 14. In the simulated driving process, the trainee P1 performs a simulated driving of the simulated course 50 (FIG. 5). At this time, the route of the simulated vehicle Vs from the start point Ps to the goal point Pg is instructed by sound from the speaker 20 and a guide arrow (not shown) displayed on the screen of the monitor 18.

  In the simulated driving process, the steering angle θh [degree] of the steering wheel 24, the opening degree θa [%] of the accelerator pedal 28, and the opening degree θb [%] of the brake pedal 30 are not shown from the start point Ps to the goal point Pg. Stored in memory. The opening degree θa of the accelerator pedal 28 is the amount of depression of the accelerator pedal 28 when the original position of the accelerator pedal 28 is 0% and the position where the accelerator pedal 28 is most depressed is 100%. Similarly, the opening θb of the brake pedal 30 is the amount of depression of the brake pedal 30 when the original position of the brake pedal 30 is 0% and the position where the brake pedal 30 is most depressed is 100%.

  FIG. 6 shows a screen 60 as an example of an operation screen displayed on the monitor 18 in the simulated operation process. As shown in FIG. 6, an operation state display frame 62 for displaying the operation state of the simulated vehicle Vs is arranged at the lower center of the screen 60 for the simulated driving process. The operation state display frame 62 includes a vehicle speed display section 64 that digitally displays the vehicle speed V [km / h], an accelerator pedal opening display section 66 that displays the opening degree θa of the accelerator pedal 28, and an opening degree of the brake pedal 30. and a brake pedal opening degree display unit 68 for displaying θb as a bar. The driver performs a simulated driving according to a simulated road environment displayed on a screen such as the screen 60.

  Returning to FIG. 4, in step S15, the computer main body 22 performs a reproduction process. In the reproduction process, the trainee P1 learns the fuel-saving driving while reproducing the movement of the simulated vehicle Vs in the simulated driving process.

  Specifically, the computer main body 22 moves the simulated vehicle Vs based on the steering angle θh of the handle 24, the opening degree θa of the accelerator pedal 28, and the opening degree θb of the brake pedal 30 stored in the simulation operation process of step S14. Reproduce. At the time of reproduction, a particularly detailed description will be given for a plurality of determination sections C1 to C7 (FIG. 5) preset for the simulation course 50. On the other hand, for the routes other than the determination sections C1 to C7, the simulated vehicle Vs on the monitor 18 is moved by fast-forwarding with some exceptions.

  Of the determination sections C1 to C7, the determination sections C1 and C5 are sections for determining fuel-saving driving (hereinafter also referred to as “soft accelerator”) during acceleration of the simulated vehicle Vs. Specifically, the starting point of the determination section C1 is set as an intersection, and the simulated vehicle Vs is stopped at the intersection. Then, the signal at the intersection changes from red to blue, and the vehicle speed V of the simulated vehicle Vs and its target value (target vehicle speed) after a predetermined time (for example, 5 seconds) from when the accelerator pedal 28 of the simulated vehicle Vs is depressed. Vtar) (for example, 20 km / h) The degree of fuel-saving driving is determined based on the difference Dv1 [km / h]. Similarly, in the determination section C5, the starting point is set to a level crossing, and the simulated vehicle Vs is stopped at the level crossing. Then, the degree of fuel-saving driving is determined based on the difference Dv1 between the vehicle speed V of the simulated vehicle Vs and the target vehicle speed Vtar after a predetermined time has elapsed from when the railroad crossing is opened and the accelerator pedal 28 of the simulated vehicle Vs is depressed. .

  Specifically, the computer main body 22 determines the threshold of the difference Dv1 for determining the degree of fuel-saving driving for the determination sections C1 and C5 {fuel-saving driving determination vehicle speed difference thresholds THdv1_eco1, THdv1_eco2 (hereinafter referred to as “thresholds THdv1_eco1, THdv1_eco2”). Is also set in advance. When the difference Dv1 is greater than or equal to a threshold THdv1_eco1 (for example, 18 km / h) and less than a threshold THdv1_eco2 (for example, 22 km / h), it is evaluated as “◯” (excellent). When the difference Dv1 is less than the threshold value THdv1_eco1, it is evaluated as “Δ” (possible). Furthermore, when the difference Dv1 is greater than or equal to the threshold value THdv1_eco2, it is evaluated as “×” (impossible).

  FIG. 7 shows a screen 70 as an example of an operation screen displayed on the monitor 18 when the soft accelerator is evaluated in the reproduction process. FIG. 8 shows a screen 80 showing the evaluation result of the soft accelerator.

  As shown in FIG. 7, a soft accelerator evaluation screen 70 has a display 72 indicating that ("soft accelerator measurement is in progress") and a display 74 indicating the evaluation criteria ("20 kilometers per hour in 5 seconds"). , And a display 76 indicating that the reproduction process is being performed (“replaying”). Further, the simulated vehicle Vs and the count value 78 are displayed on the monitor 18. Note that “1” of the count value 78 in FIG. 7 indicates that it is 1 second from the start of measurement.

  The computer main body 22 advances the moving image display from the screen 70 of FIG. 7, and displays the screen 80 of FIG. 8 at the end of the determination section. Meanwhile, the operation state display frame 62 continues to be displayed on the monitor 18. For this reason, the trainee P1 can confirm changes in the vehicle speed V, the opening degree θa of the accelerator pedal 28, and the opening degree θb of the brake pedal 30 during the reproduction.

  In addition, the screen 80 of FIG. 8 includes a “x” display 82 and a “soft accelerator is still out” display 84 as the evaluation results of the soft accelerator. In addition to the displays 82 and 84, the evaluation result may be output by voice. Note that “5” of the count value 78 in FIG. 8 indicates that it is 5 seconds from the start of measurement. As can be seen from FIGS. 7 and 8, the count value 78 is counted up from 1 to 5.

  When entering the determination section C1 that appears first among the determination sections C1 and C5, an explanation screen (not shown) regarding the soft acceleration may be displayed and a description of the soft acceleration may be output by voice. Alternatively, the same processing can be performed in the determination section C5. As an explanation regarding the soft acceleration, for example, it is better not to step on the accelerator pedal 28 at a stretch, but to depress it slowly, and it is possible to waste 170 cc of carbon dioxide after 10 sudden starts. .

  The determination sections C2 and C6 are sections for determining fuel-saving driving when the simulated vehicle Vs travels at a constant speed (cruise traveling). Specifically, determination sections C2 and C6 are set in sections where the vehicle speed V of the simulated vehicle Vs is considered to be stable, and the degree of fuel-saving driving is determined based on the opening θa of the accelerator pedal 28 in the determination sections C2 and C6. Determine.

  Specifically, the computer main body 22 sets a threshold value of the maximum value Dθ_max for determining the degree of fuel-saving driving {fuel-saving driving determination opening threshold value THθ_eco1, THθ_eco2 (hereinafter also referred to as “threshold values THθ_eco1, THθ_eco2”)}. Set it. The maximum value Dθ_max is obtained as follows. That is, at the start point of each of the determination sections C2 and C6, the opening degree θa of the accelerator pedal 28 (the opening degree θast at the measurement start time) is measured, and the difference Dθ between the opening degree θast at the measurement start time and the subsequent opening degree θa is sequentially determined. To do. The maximum absolute value of the difference Dθ is defined as a maximum value Dθ_max. When the maximum value Dθ_max is less than or equal to a threshold THθ_eco1 (for example, 5%), it is evaluated as “◯” (excellent). When the maximum value Dθ_max exceeds the threshold THθ_eco1 and is equal to or less than the threshold THθ_eco2 (for example, 15%), it is evaluated as “Δ” (possible). Further, when the maximum value Dθ_max exceeds the threshold value THθ_eco2, it is evaluated as “×” (impossible).

  Further, the computer main body 22 determines the threshold value Dv2 between the target vehicle speed Vtar2 and the vehicle speed V as the speed limit for the determination sections C2 and C6 {vehicle speed difference threshold values THdv2_eco1 and THdv2_eco2 (hereinafter also referred to as “threshold values THdv2_eco1 and THdv2_eco2”)}. Is set in advance. When the difference Dv2 is greater than or equal to a threshold THdv2_eco1 (for example, −5 km / h) and less than or equal to a threshold THdv2_eco2 (for example, 0 km / h), an evaluation that the vehicle speed V is appropriate is output in the first result display process described later. . When the difference Dv2 is less than the threshold value THdv2_eco1, an evaluation that the vehicle speed V is too low is output in the first result display process. Further, when the difference Dv2 exceeds the threshold value THdv2_eco2, an evaluation that the vehicle speed V is too high is output in the first result display process. The target vehicle speed Vtar2 as the speed limit is indicated on the road sign arranged on the route before entering the determination sections C2 and C6.

  As described above, in the determination sections C <b> 2 and C <b> 6, the degree of fuel-saving driving during constant speed traveling is determined based on the evaluation regarding the maximum value Dθ_max. In addition, based on the evaluation regarding the difference Dv2, in the first result display process to be performed later, the evaluation regarding the level of the vehicle speed V is performed.

  FIG. 9 shows a screen 90 as an example of a driving screen displayed on the monitor 18 when evaluating fuel-saving driving at the time of constant speed driving in the reproduction process. FIG. 10 shows a screen 100 showing the evaluation result of the fuel-saving driving at the time of constant speed traveling.

  As shown in FIG. 9, on the screen 90 under evaluation during constant speed driving, a display 92 indicating that (“cruising driving measurement”) and a display 94 indicating the evaluation criteria (“limit speed 50 km”), , And a display 76 indicating that the reproduction process is being performed (“replaying”). Further, the simulated vehicle Vs is displayed on the monitor 18.

  The moving image display is advanced from the screen 90 of FIG. 9, and the screen 100 of FIG. 10 is displayed at the end of the determination sections C2 and C6. Meanwhile, the operation state display frame 62 continues to be displayed on the monitor 18. For this reason, the trainee P1 can confirm changes in the vehicle speed V, the opening degree θa of the accelerator pedal 28, and the opening degree θb of the brake pedal 30 during the reproduction.

  In addition, the screen 100 of FIG. 10 includes a “◯” display 102 and a “stable accelerator operation is performed” display 104 as evaluation results during constant speed traveling. In addition to the displays 102 and 104, the evaluation result may be output by voice.

  In addition, when entering the determination section C2 that appears first among the determination sections C2 and C6, a description regarding fuel-saving driving during constant speed traveling is output by voice. It may be displayed on the monitor 18. Alternatively, the same processing can be performed in the determination section C6. As an explanation for fuel-saving driving during constant speed driving, for example, when driving with less acceleration / deceleration during driving, or when there is a preceding vehicle, the opening degree θa of the accelerator pedal 28 is kept constant with sufficient inter-vehicle distance. Can be mentioned.

  The determination sections C3, C4, and C7 are sections for determining fuel-saving driving (accelerator off) when the simulated vehicle Vs is decelerated. Specifically, the determination section C3 is set to a section where the simulated vehicle Vs stops at the intersection, the determination section C4 is set to a section where the simulated vehicle Vs stops at the crossing, and the determination section C7 is It is set in a section where the simulation vehicle Vs decelerates downhill. Then, the simulation vehicle Vs is decelerated and stopped in the determination sections C3 and C4, and the simulation vehicle Vs is decelerated in the determination section C7. At this time, the computer main body 22 determines a point where an accelerator off operation (for example, an operation for setting the opening degree θa of the accelerator pedal 28 to zero) is performed in the determination sections C3, C4, and C7.

  More specifically, for the determination section C3, a distance Dc1 between the simulated vehicle Vs and an intersection stop line (not shown) is used. For the determination section C4, a distance Dc2 between the simulated vehicle Vs and a stop line (not shown) before the crossing is used. For the determination section C7, the distance Dc3 from the deceleration start target point to the point where the accelerator-off operation is actually performed is used. Then, the degree of fuel-saving driving is determined based on the distances Dc1, Dc2, and Dc3.

  That is, the computer main body 22 presets thresholds of distances Dc1 to Dc3 for determining the degree of fuel-saving driving {fuel-saving driving determination distance thresholds THdc_eco1, THdc_eco2 (hereinafter also referred to as "thresholds THdc_eco1, THdc_eco2")}. deep. When the distances Dc1 to Dc3 are equal to or greater than the threshold THdc_eco1 (for example, a distance of 3/4 of the entire determination section C3 and C4), the evaluation is “◯” (excellent). Further, when the distances Dc1 to Dc3 are less than the threshold THdc_eco1 and greater than or equal to the threshold THdc_eco2 (for example, a distance of 1/4 of the entire determination section C3 and C4), the evaluation is “Δ” (possible). Further, when the distances Dc1 to Dc3 are equal to or less than the threshold value THdc_eco2, it is evaluated as “x” (impossible).

  FIG. 11 shows a screen 110 as an example of an operation screen displayed on the monitor 18 when the accelerator-off evaluation is performed in the reproduction process. FIG. 12 shows a screen 120 showing the accelerator off evaluation result.

  As shown in FIG. 11, an accelerator evaluation screen 110 displays a display 112 indicating that ("early accelerator-off measurement is in progress"), and indicates that the accelerator-off section is to be used ("accelerator-off area"). Display 114 and a display 76 indicating that the reproduction process is being performed (“replaying”). Further, the simulated vehicle Vs is displayed on the monitor 18.

  The moving image display is advanced from the screen 110 of FIG. 11, and the screen 120 of FIG. 12 is displayed at the end of the determination section. Meanwhile, the operation state display frame 62 continues to be displayed on the monitor 18. For this reason, the trainee P1 can confirm changes in the vehicle speed V, the opening degree θa of the accelerator pedal 28, and the opening degree θb of the brake pedal 30 during the reproduction.

  In addition, the screen 120 of FIG. 12 includes a display 122 of “Δ” and a display 124 of “Acceleration off is delayed” as an accelerator off evaluation result. In addition to the displays 122 and 124, the evaluation result may be output by voice.

  In addition, when entering the determination section C3 that appears first among the determination sections C3, C4, and C7, an explanation screen (not shown) regarding accelerator-off may be displayed and a description of accelerator-off may be output by voice. Alternatively, the same processing can be performed in the determination sections C4 and C7. As an explanation for accelerator off, for example, by predicting the stop position and turning off the accelerator early, it is better to cut the fuel early using the engine brake before using the foot brake. On the downhill, it is possible to improve the fuel efficiency while maintaining the sufficient vehicle speed V by turning off the accelerator before the downhill.

  As described above, in the reproduction process, the degree of fuel-saving driving related to the operation is evaluated while reproducing the operation of the trainee P1 in the simulation driving process in the determination sections C1 to C7.

  Returning to FIG. 4, in step S16, the computer main body 22 performs a first result display process. The first result display process is a process for displaying the result of the simulated operation process.

  FIG. 13 shows a screen 130 as an example of a screen displayed on the monitor 18 in the first result display process. As shown in FIG. 13, the computer main body 22 has an opening θa of the accelerator pedal 28 in the simulated operation process (also referred to as “opening θ1” for distinction from an opening θa in the re-simulation operation process described later). The opening of the accelerator pedal 28 in an ideal operation (ideal opening θt) [%] is displayed. As the ideal opening degree θt, for example, data when a driver who is proficient in fuel-saving driving operates the accelerator pedal 28 can be used. Alternatively, a simulation value may be used.

  Further, the computer main body 22 displays a region where the opening θ1 is larger than the ideal opening θt as a waste portion Rw1, and displays a region where the opening θ1 is smaller than the ideal opening θt as a saving portion Rs1. . The screen 130 of FIG. 13 further includes an evaluation result and advice display 132 in the determination sections C1 to C7, and a rank display 134 as the evaluation result of the simulated operation.

  FIG. 14 shows a screen 140 as another example of the display screen of the monitor 18 in the first result display process. The screen 140 is displayed after the screen 130 of FIG. As shown in FIG. 14, the computer main body 22 displays the fuel-saving driving when a standard model vehicle is assumed and the simulated driving in the simulated driving process in comparison. That is, on the screen 140, the average fuel consumption, the gasoline consumption under a predetermined condition, the difference in gasoline consumption, the profit / loss associated with the difference, and the carbon dioxide emission associated with the difference are simulated in the standard fuel-saving driving and the simulated driving process. The numerical value compared with driving is displayed. Therefore, the importance of fuel-saving driving can be shown with specific numerical values.

  Returning to FIG. 4, in step S <b> 17, the computer main body 22 performs a re-simulation operation process. The re-simulation driving process is the same as the simulation driving process in step S14, and the trainee P1 who has performed driving training and learning with the above-described contents performs the simulated driving again. The simulated course 50 is the same, and the route from the start point Ps to the goal point Pg is the same.

  In step S18, the computer main body 22 performs a reproduction process. The reproduction process here is to reproduce the re-simulation operation in the re-simulation operation process of step S17, and the specific process is the same as the reproduction process of step S15.

  In step S19, the computer main body 22 performs a second result display process. The second result display process is basically the same as the first result display process in step S16, but the displayed result is not only the evaluation result of the re-simulation operation process (S17) but also the simulation operation process (S14). The evaluation result is also displayed.

  FIG. 15 shows a screen 150 as an example of a screen displayed on the monitor 18 in the second result display process of step S19. As shown in FIG. 15, the computer main body 22 distinguishes the opening θ1 of the accelerator pedal 28 in the simulated driving process and the opening θa of the accelerator pedal 28 in the re-simulating driving process (to distinguish from the opening θ1 in the simulated driving process). "Opening angle θ2") and ideal opening angle θt are displayed. Further, the computer main body 22 displays an area where the opening degree θ2 is larger than the opening degree θ1 as a waste part Rw2, and displays an area where the opening degree θ2 is smaller than the opening degree θ1 as a saving part Rs2. The screen 150 of FIG. 15 further includes an evaluation result and advice display 152 in the determination sections C1 to C7 for the resimulation operation processing, and a rank display 154 as the evaluation result of the resimulation operation.

  FIG. 16 shows a screen 160 as an example of a screen displayed on the monitor 18 in the second result display process of step S19. The screen 160 is displayed after the screen 150 in FIG. As shown in FIG. 16, the computer main body 22 displays the simulated operation in the simulated operation process and the re-simulated operation in the re-simulated operation process in comparison. In other words, on the screen 160, the average fuel consumption, the gasoline consumption under a predetermined condition, the difference in gasoline consumption, the profit / loss associated with the difference, and the carbon dioxide emissions associated with the difference are simulated driving and resimulation driving processing, respectively. The numerical value that compares is displayed. Therefore, the improvement degree of the fuel-saving driving can be indicated by specific numerical values.

  Returning to FIG. 4, in step S <b> 20, the computer main body 22 inquires of the trainee P <b> 1 whether or not it is necessary to retry the re-simulation operation process, that is, whether or not the simulation operation is to be performed again. The inquiry about the necessity of retry can be made by, for example, displaying the fact on the monitor 18 and outputting a voice.

  When the trainee P1 inputs that a retry is required (S20: YES), the process returns to step S17 and the re-simulation operation process is performed again. In this case, what is used in the second result display process of step S19 is the result of the previous re-simulation operation process and the current re-simulation operation process. Alternatively, in addition to these, the result of the first simulated operation process may be used. In this way, the trainee P1 can repeat the simulated driving until he is satisfied.

  If there is an input from the trainee P1 indicating that no retry is required (S20: NO), in step S21, the computer main body 22 performs an ending effect process. Specifically, other notices related to fuel-saving driving are displayed on the monitor 18 and voices are output for the notices. Other points to consider include, for example, lightening the load on the vehicle, removing extra equipment, running without waste on a planned drive, and regularly checking the tire air pressure to determine the optimum value. Keeping it, stopping idling when parked, and opening the window as much as possible to refrain from using the air conditioner. Thereafter, a message regarding the importance of fuel-saving driving is displayed and the message is output as a voice.

  When the ending effect process is finished, the ecology mode is finished, and the process returns to the user menu (S2 in FIG. 3).

  As described above, according to the present embodiment, while reproducing the simulated driving of the trainee P1, in each of the determination sections C1 to C7, the fuel saving driving information related to the simulated driving (each determination section C1 to C7). The fuel-saving driving points and evaluation criteria, etc.) and the evaluation of fuel-saving driving for simulated driving are output in video and audio. Therefore, the trainee P1 can check the fuel-saving driving information related to the simulated driving and the evaluation of the simulated driving while reviewing his / her simulated driving. Therefore, the trainee P1 can grasp the self-improvement point regarding the fuel-saving driving with a real feeling. Further, when the simulated operation is reproduced, the opening degree θa of the accelerator pedal 28 and the vehicle speed V of the simulated vehicle Vs are displayed on the monitor 18. For this reason, since the opening degree θa and the vehicle speed V can be visually confirmed, it is possible to convey the evaluation of the simulated driving related to fuel saving to the trainee P1 in a convincing manner. Therefore, it is possible to effectively train fuel-saving driving.

  In the present embodiment, the computer main body 22 uses the opening degree θa of the accelerator pedal 28 for the determination sections C2 and C6 related to constant speed travel as an index, and the operation timing of the accelerator pedal 28 for the determination sections C3, C4, and C7 related to deceleration as an index. Evaluate simulated driving. Thereby, since the simulation driving is evaluated based on the opening degree θa of the accelerator pedal 28 or the operation timing, it is possible to easily evaluate the degree of fuel-saving driving by setting a threshold value and a range for evaluation. In addition, it is possible to perform driving training on the operation of the accelerator pedal 28, which is the basis of fuel consumption, from the viewpoint of an operation for suppressing fuel consumption. For this reason, it can be expected to greatly contribute to the spread of fuel-saving driving for deceleration driving and cruise driving by operating the accelerator pedal 28.

  In the second result display process according to the present embodiment, the computer main body 22 superimposes the transitions of the opening degrees θ1 and θ2 of the accelerator pedal 28 in the simulated operation process and the resimulation operation process on the monitor 18 so as to overlap with the transition of the ideal opening degree θt. To display. Accordingly, it is possible to compare the opening θ1 in the first simulated operation with the opening θ2 in the second simulated operation on the basis of the ideal opening θt. Therefore, it is possible to visually confirm the improvement status of the second simulated operation compared to the first simulated operation and the waste situation of the fuel consumption in the first and second simulated operations.
