According to this kind of driving evaluation technique, the driver can try to improve driving thereafter based on the output driving advice. However, since the conventional technique only outputs driving advice unilaterally, even if the driver attempts to improve driving, the driver cannot grasp whether or not driving has actually been improved.
Therefore, the present invention provides a driving evaluation device that can grasp that driving is actually improved when driving improvement is attempted based on the output driving advice.

According to the driving evaluation apparatus of the present invention, the driving advice output means outputs driving advice when the vehicle behavior detected by the vehicle behavior detection means is outside the reference range. Then, after the driving advice is output, the behavior determining means determines whether or not the behavior detected by the vehicle behavior detecting means is within the reference range. When the behavior determining means determines that “the behavior is within the reference range”, the driving improvement result output means outputs a driving improvement result indicating that the driving of the vehicle has been improved.
As a result, when the driver attempts to improve driving based on the output driving advice, driving performance is output in response to the subsequent behavior of the vehicle being improved within the reference range. Therefore, the driver can grasp that the driving is actually improved based on the output of the driving improvement result.

(First embodiment)
A driving evaluation apparatus 10 illustrated in FIG. 1 is mounted on a vehicle, for example, and includes a control unit 11, a vehicle behavior detection unit 12, a display output unit 13, a voice output unit 14, an operation input unit 15, and the like. The control unit 11 includes a CPU, RAM, ROM, and the like (not shown), and controls the overall operation of the driving evaluation apparatus 10. Further, the control unit 11 executes a control program in the CPU so that the driving advice output processing unit 21, the behavior determination processing unit 22, the driving improvement result output processing unit 23, and the reference range setting processing unit 24 are virtualized by software. Realize. In addition, you may implement | achieve these process parts 21-24 as hardware as an integrated circuit integrated with the control part 11, for example.

  The vehicle behavior detection unit 12 is an example of vehicle behavior detection means, and includes, for example, an acceleration sensor 121 that detects vehicle acceleration, a speed sensor 122 that detects vehicle speed, and an engine speed sensor 123 that detects engine speed. Various sensors for detecting the behavior of the vehicle, such as a winker sensor 124 for detecting the operating state of the winker, are provided. The vehicle behavior detection unit 12 outputs vehicle behavior data indicating the behavior of the vehicle detected by various sensors to the control unit 11.

  The display output unit 13 includes, for example, a liquid crystal display, an organic EL display, and the like. The display output unit 13 outputs various visual information based on various display output data input from the control unit 11. The audio output unit 14 includes, for example, a vehicle-mounted speaker.

The driving advice output processing unit 21 is an example of a driving advice output unit, and when the behavior detected by the vehicle behavior detection unit 12 deviates from a preset reference range, the behavior of the vehicle is out of the reference range. Outputs driving advice to the effect or to promote driving improvement. That is, for example, when the detected speed of the vehicle is faster than a preset reference speed, the driving advice output processing unit 21 outputs driving advice indicating that the speed of the vehicle is too high or that the vehicle is to be decelerated. Although detailed explanation is omitted, the driving advice output processing unit 21 also detects other behaviors such as the acceleration of the vehicle and the engine speed, for example, when the detected behavior is outside a preset reference range. Driving advice indicating that the behavior is out of the reference range or promoting the improvement of driving is output.
In this case, the driving advice output processing unit 21 is set to output driving advice by voice via the voice output unit 14. The driving advice output processing unit 21 may be set to output driving advice by display via the display output unit 13, or may be set to output driving advice by both sound and display. Good.

  The behavior determination processing unit 22 is an example of a behavior determination unit. After the driving advice output processing unit 21 outputs driving advice, the behavior detected by the vehicle behavior detection unit 12 returns to a preset reference range. It is determined whether or not. That is, for example, when a driving advice is output based on the fact that the detected speed of the vehicle is faster than a preset reference speed, the behavior determination processing unit 22 determines that the detected vehicle speed is higher than the reference speed. It is determined whether or not it has become late. Although detailed explanation is omitted, the behavior determination processing unit 22 also outputs driving advice based on the fact that other behaviors such as vehicle acceleration and engine speed are out of the reference range, for example. It is determined whether or not the detected vehicle behavior has returned to the reference range.

That is, for example, when the driving advice is output based on the fact that the detected speed of the vehicle is faster than a preset reference speed, and the vehicle speed becomes slower than the reference speed, the driving improvement result output processing unit 23 outputs a driving improvement record indicating that the speed of the vehicle is slower than the reference speed and the driving is improved. Although detailed explanation is omitted, the driving improvement result output processing unit 23 outputs the driving advice based on the fact that other behaviors such as the acceleration of the vehicle and the engine speed are out of the reference range. Even when the behavior returns to the reference range, the driving improvement result indicating that the behavior of the vehicle is within the reference range and the driving is improved is output.
In this case, the driving improvement result output processing unit 23 is set to output the driving improvement result by voice via the voice output unit 14. The driving improvement result output processing unit 23 may be set to output the driving improvement result by display via the display output unit 13, or set to output the driving improvement result by both voice and display.

In this case, on the setting screen S1, the reference speed on the general road and the reference speed on the highway can be set, and the user can appropriately set a desired reference speed by operating the setting button Ba. it can. The reference range setting processing unit 24 sets the reference speed based on the numerical value input via the setting screen S1. Then, the driving advice output processing unit 21 and the behavior determination processing unit 22 determine that the behavior of the vehicle is out of the reference range when the vehicle detection speed is faster than the set reference speed, and set the reference speed set. If the detection speed of the vehicle is slower than that, it is determined that the behavior of the vehicle is within the reference range.

  Furthermore, on the setting screen S1, these reference speeds can be set at a plurality of levels. For example, when a vehicle travels on a general road, when determining the behavior of the vehicle at a “level 1” reference speed, whether the detected speed is out of the reference range or within the reference range based on 60 km / h When the vehicle behavior is determined at the reference speed of “level 3”, it is determined whether the detected speed is out of the reference range or within the reference range with reference to 50 km / h. Which level of reference value is used to determine the behavior of the vehicle can be set, for example, via a level setting screen R shown in FIG. That is, on the level setting screen R, a speed diagnosis level, a rapid acceleration diagnosis level, a rapid deceleration diagnosis level, a sudden turn diagnosis level, and an engine speed diagnosis level can be set. The user can appropriately set a desired level by operating the setting buttons Bb.

  Although not described in detail, the reference range setting processing unit 24 can display various setting screens for vehicle behavior diagnosis on the display output unit 13 in addition to the setting screen S1 for speed diagnosis. That is, the reference range setting processing unit 24 is, for example, a setting screen for engine speed diagnosis for setting a reference range related to the engine speed diagnosis of the vehicle, and a reference range related to the rapid acceleration diagnosis of the vehicle. Setting screen for sudden acceleration diagnosis, setting screen for sudden deceleration diagnosis for setting the reference range for sudden deceleration diagnosis of the vehicle, setting for sudden turning diagnosis for setting the reference range for sudden turning diagnosis of the vehicle A screen or the like can also be displayed by switching to the display output unit 13. Through various setting screens displayed on the display output unit 13, the user can use a reference value for engine speed diagnosis, a reference value for rapid acceleration diagnosis, a reference value for rapid deceleration diagnosis, or a reference for sudden turn diagnosis. A value etc. can be set. Further, the reference range setting processing unit 24, for example, various reference ranges for vehicle behavior diagnosis based on input information input from an external personal computer or the like different from the driving evaluation apparatus 10 via a wireless line or a wired line. Can also be set.

Next, an example of the driving evaluation process by the driving evaluation device 10 will be described. That is, as shown in FIG. 4, when the vehicle starts traveling, the driving evaluation device 10 determines whether or not the vehicle behavior detected by the vehicle behavior detection unit 12 is outside a preset reference range. (A1). When the detected vehicle behavior is out of the reference range (A1: YES), the driving evaluation device 10 determines that the vehicle behavior is out of the reference range or sets the vehicle behavior within the reference range. The driving advice to the effect of prompting is output (A2).
When the driving evaluation device 10 outputs driving advice, the driving evaluation device 10 determines whether or not the behavior of the vehicle detected after the driving advice is within a preset reference range (A3). When the behavior of the vehicle detected after the driving advice is output returns to the reference range (A3: YES), the driving evaluation device 10 determines whether or not a predetermined time has elapsed since the driving advice was output. Is determined (A4). The predetermined time can be changed and set as appropriate.

  When the predetermined time has not elapsed since the output of the driving advice (A4: NO), the driving evaluation device 10 proceeds to step A3 and determines whether or not the behavior of the vehicle has returned to the reference range. Run again. In other words, the driving evaluation device 10 repeatedly determines whether or not the behavior of the vehicle after the driving advice is output is within the reference range over a predetermined time after the driving advice is output. Then, when a predetermined time has elapsed from the output of the driving advice (A4: YES), the driving evaluation device 10 outputs a driving improvement result indicating that the driving of the vehicle has been improved (A5), and ends this processing. . That is, the driving evaluation device 10 outputs driving improvement results when a state in which the behavior of the vehicle is within the reference range continues for a predetermined time after the driving advice is output. In addition, the driving | running evaluation apparatus 10 transfers to step A1, when the behavior of the vehicle detected after the output of driving advice is out of a reference range (A3: NO).

  According to the driving evaluation apparatus 10 according to the present embodiment, driving advice is output when the behavior of the vehicle falls outside a preset reference range while the vehicle is running, and the driver drives based on the output driving advice. Can try to improve. When the driver tries to improve driving based on the output driving advice, the driving performance is improved according to the subsequent behavior of the vehicle returning to the reference range, that is, the driving is improved. Is output. Therefore, the driver can grasp that the driving is actually improved based on the output of the driving improvement result.

Further, according to the driving evaluation apparatus 10, the determination as to whether or not the behavior of the vehicle is within the reference range is repeatedly performed over a predetermined time after the driving advice is output. As a result, driving improvement results are output when the vehicle behavior returns to the reference range for a certain period of time, not when the vehicle behavior temporarily returns to the reference range, Can be continuously improved.
Moreover, according to the driving | running evaluation apparatus 10, a driving | operation improvement performance is output with a sound. As a result, the driver can be audibly notified that the driving has actually improved, and the driver can confirm that the driving has actually improved while keeping his line of sight in the forward direction of the vehicle. I can grasp it.

  Further, according to the driving evaluation device 10, the reference range setting processing unit 24 can appropriately change and set the reference range for vehicle behavior diagnosis. As a result, the reference range can be adjusted as appropriate in consideration of the driving tendency of the driver, for example, and detailed driving evaluation can be performed. Further, for example, a different reference range can be set for each vehicle or for each driver, and driving evaluation according to each vehicle or each driver can be performed.

It is determined whether or not the behavior of the vehicle detected in is within a preset reference range (B3). Then, when the behavior of the vehicle after the driving advice is output returns to the reference range (B3: YES), the driving evaluation device 10 outputs a driving improvement result accordingly (B4) and proceeds to Step B5. Transition. On the other hand, when the behavior of the vehicle after outputting the driving advice is out of the reference range (B3: NO), the driving evaluation device 10 proceeds to step B5 without outputting the driving improvement record.

When the driving evaluation device 10 proceeds to step B5, the driving evaluation device 10 determines whether or not a predetermined time has elapsed after completing the determination of whether or not the behavior of the vehicle is within the reference range (B5). The predetermined time can be changed and set as appropriate. The predetermined time in step B5 may be set regardless of the predetermined time in step A4 described above, or may be set in association with it.
Then, when a predetermined time has elapsed since the completion of the previous behavior determination (B5: YES), the driving evaluation device 10 proceeds to step B3 and again determines whether or not the behavior of the vehicle is within the reference range. To do. That is, the driving evaluation device 10 repeatedly determines whether the behavior of the vehicle is within the reference range at predetermined time intervals after the driving advice is output. The driving evaluation device 10 continues this process until the vehicle stops.

  According to the driving evaluation device 10 according to the present embodiment, even if driving is improved after driving advice is output and driving performance is output, vehicle behavior determination is repeatedly performed at predetermined time intervals thereafter. When the detected behavior of the vehicle is within the reference range and the driving is improved, the driving improvement result is output again. Thereby, the presence or absence of the driving | running improvement after the output of driving advice can be continuously evaluated.

(Third embodiment)
In the present embodiment, the content of the driving evaluation process by the driving evaluation device 10 is different from the above-described embodiment. That is, as shown in FIG. 6, the driving evaluation device 10 outputs a driving advice in accordance with the behavior detected while the vehicle is running (C1: YES) and outputs driving advice accordingly (C2). It is determined whether or not the behavior of the vehicle detected in step 1 is within a preset reference range (C3). This determination may be performed over a predetermined time after the driving advice is output, may be repeatedly performed at predetermined time intervals after the driving advice is output, or a combination of these may be performed. Also good.

  When the behavior of the vehicle detected after the driving advice is output returns to the reference range (C3: YES), the driving evaluation device 10 determines whether the driving of the vehicle has ended (C4). . Note that the completion of driving of the vehicle can be determined based on, for example, that an ignition switch (not shown) is turned off. Then, when the driving of the vehicle is finished (C4: YES), the driving evaluation device 10 outputs a driving improvement result (C5) and ends this process.

  According to the driving evaluation apparatus 10 according to the present embodiment, the driving improvement result is output when the driving of the vehicle is finished. As a result, the driving improvement results can be notified to the driver in general after the driving is completed, and the driver can utilize the improvement results in the completed driving at the next driving.
