[0003] [Patent Document 1] JP 2011-159215 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the technology described in the above Patent Document 1, a comprehensive evaluation result for the most recent driving operation is presented to the driver based on the evaluation points of various driving operations performed within a predetermined time.

[0019] Hereinafter, a driving evaluation system S including a driving evaluation display device 10 according to this embodiment will be described with reference to Figs.

[0020] As shown in Fig. 1, the driving evaluation system S of this embodiment is configured to include a driving evaluation display device 10 mounted on a vehicle V and a server 12. The vehicle V and the server 12 are connected to a network N. Although a plurality of vehicles V are connected to the network N, only one vehicle V is shown in Fig. 1 for ease of explanation.

[0021] The driving evaluation display device 10 of the present embodiment is a control device provided in a vehicle V, as an example.

[0022] The server 12 is owned by an administrator of multiple vehicles V. That is, the server 12 is owned by an administrator who manages multiple vehicles V, and in this embodiment, as an example, the vehicles V are used as taxis that carry users. The server 12 is owned by a taxi company.

[0023] Here, the vehicle V acquires operation data of the driving operations performed by the driver while traveling and transmits it to the server 12. The server 12 evaluates the driving operations of the driver based on the operation data by executing a pre-stored program. The driving evaluation display device 10 acquires the evaluation results of the driving operations and displays an evaluation image reflecting the display results on the display unit 23 (23A, 23B, 23C) provided in front of the driver's seat of the vehicle V.

[0024] 2, the display unit 23 is configured with a display provided at the front part of the interior of the vehicle V.

[0025] The display unit 23 may be configured as a meter display 23A provided in front of the driver's seat on one side of the instrument panel 14 in the vehicle width direction (the right side in FIG. 2).

[0026] The display unit 23 may be configured as a display 23B provided in the center of the instrument panel 14 in the vehicle width direction, on the vehicle front side of the driver's seat.

[0027] The display unit 23 may be configured as a projection surface 23C (windshield glass 18) of a head-up display device (not shown) on the vehicle front side of the instrument panel 14. In this case, the driving evaluation display device 10 is included in the head-up display device.

[0028] The display unit 23 may be a display of a user terminal installed in front of the driver's seat. The user terminal is, for example, a portable terminal such as a smartphone or a tablet. In this case, the driving evaluation display device 10 may be an external configuration of the user terminal or an internal configuration of the user terminal.

[0029] (Hardware configuration of driving evaluation display device 10) Fig. 3 is a block diagram showing a hardware configuration of the driving evaluation display device 10. As shown in Fig. 3, the driving evaluation display device 10 includes a CPU (Central Processing Unit: processor) 20, a ROM (Read Only Memory) 22, a RAM (Random Access Memory) 24, a storage 26, a communication I / F (communication interface) 28, and an input / output I / F (input / output interface) 30. Each component is connected to each other via a bus 32 so as to be able to communicate with each other.

[0030] The CPU 20 is a central processing unit that executes various programs and controls each part. That is, the CPU 20 reads a program from the ROM 22 or the storage 26, and executes the program using the RAM 24 as a working area. The CPU 20 controls each of the above components and performs various arithmetic processing according to the program recorded in the ROM 22 or the storage 26.

[0031] The ROM 22 stores various programs and various data. The RAM 24 temporarily stores programs or data as a working area. The storage 26 is configured with an HDD (Hard Disk Drive) or an SSD (Solid State Drive) and stores various programs including an operating system and various data. In this embodiment, the ROM 22 or the storage 26 stores programs and various data for performing the driving evaluation display process.

[0032] The communication I / F 28 is an interface for the driving evaluation display device 10 to communicate with the server 12 and other devices such as the data logger 38 described later, and uses standards such as CAN (Controller Area Network), Ethernet (registered trademark), LTE (Long Term Evolution), FDDI (Fiber Distributed Data Interface), and Wi-Fi (registered trademark).

[0033] Here, the communication I / F 28 communicates with a data logger 38 mounted on the vehicle V.

[0034] The data logger 38 is configured to be able to communicate with ECUs (Electronic Control Units) mounted on various in-vehicle sensors via an in-vehicle network such as a Controller Area Network (CAN) or Ethernet (registered trademark). The in-vehicle sensors are a group of sensors for detecting operation data related to the driver's driving operations. The types of the in-vehicle sensors are not particularly limited, but may be configured, for example, by an internal camera that photographs the interior of the vehicle V, an external camera that photographs the surroundings of the vehicle V, a driving monitor, an accelerator position sensor, a brake sensor, and the like.

[0035] The data logger 38 of this embodiment can acquire operation data related to the driving operation of the driver detected by the in-vehicle sensor and transmit the data to the driving evaluation display device 10 via the communication I / F 28. The data logger 38 also transmits the acquired operation data to the server 12. The server 12 accumulates the operation data transmitted from the data logger 38.

[0036] The input / output I / F 30 is electrically connected to an input unit 34 and a display unit 36. The input unit 34 is a device for inputting predetermined instructions to the driving evaluation display device 10, and is composed of, for example, operation buttons or an operation panel installed around the driver's seat. The display unit 36 ​​is a device such as a display for displaying information output from the driving evaluation display device 10. In addition, when the driving evaluation display device is composed of a tablet or the like, the input unit 34 and the display unit 36 ​​may be integrally configured by a touch-operated display or the like.

[0037] (Functional configuration of driving evaluation display device 10) The driving evaluation display device 10 realizes various functions using the above hardware resources. The functional configuration realized by the driving evaluation display device 10 will be described with reference to FIG.

[0038] 4, the driving evaluation display device 10 includes, as functional components, an evaluation acquisition unit 62 and a display control unit 64. Each functional component is realized by the CPU 20 reading and executing a program stored in the ROM 22 or the storage 26.

[0039] The evaluation acquisition unit 62 acquires an evaluation result for a preset driving operation based on operation data acquired during driving. In one example of the present embodiment, this evaluation result is calculated by executing a program stored in the server 12. The evaluation acquisition unit 62 receives the evaluation result transmitted from the server 12, thereby acquiring the evaluation result for the driver's driving operation.

[0040] (Evaluation method for driving operation) An example of a method for evaluating driving operations will be described. In this embodiment, the accelerator operation and the brake operation of the driver are evaluated. Specifically, for each operation, a quantitative score is calculated based on operation data acquired during driving, and based on the calculated score, an evaluation result for each operation is calculated in three stages, namely, "OK judgment", "NG judgment", and "danger judgment".

[0041] An "OK judgment" is an evaluation result that indicates that the driving operation is good. An "NG judgment" is an evaluation result that indicates that the driving operation is poor. A "danger judgment" is an evaluation result that indicates that the operation is highly dangerous and threatens the safe driving of the vehicle V.

[0042] The accelerator operation is evaluated for starting and rapid acceleration. Specifically, the accelerator opening detected by the accelerator position sensor and the time required to reach a predetermined accelerator opening are acquired as operation data.

[0043] For example, in the item of transmission, the score may be calculated based on the time it takes for the vehicle V to reach a predetermined accelerator opening from a stopped state. Also, the score of the most ideal starting state may be set to 100, and the score of the starting state in which the accelerator opening is fully opened from a stopped state may be set to 0, and the score may be calculated by comparing with the actual starting state.

[0044] In the item of sudden acceleration, the degree of sudden acceleration is calculated as a score. The change in the accelerator opening detected by the accelerator position sensor and the time required to reach a predetermined change are acquired as operation data. If the predetermined change is reached in a relatively short time, the score may be calculated to be low.

[0045] Brake operation is evaluated for sudden braking and stopping. In the sudden braking category, the degree to which sudden braking was performed is calculated as a score. For example, the change in the amount of depression of the brake pedal detected by a brake sensor and the time required to reach a predetermined amount of change are acquired as operation data. If the predetermined amount of change is reached in a relatively short time, a low score may be calculated. In addition, in the stopping category, the score may be calculated based on the time required for the vehicle V to stop from a predetermined speed.

[0046] The scores for the accelerator operation and the brake operation may be calculated based on an acceleration sensor provided in the vehicle V. That is, the starting, sudden acceleration, sudden braking, and stopping of the vehicle may be determined based on the amount of change in acceleration within a predetermined time, and the scores may be calculated based on the degree of these.

[0047] The server 12 holds a table in which operation items, scores, and evaluation results are associated with respect to accelerator operation and brake operation, and performs evaluation of the driving operation by referring to this table.

[0048] The above evaluation of the driving operation may be performed, for example, at a predetermined time interval.

[0049] In this embodiment, the evaluation of the driver's driving performance is performed by executing a program stored in the server 12, but the present invention is not limited to this. The driving performance may be evaluated by the driving evaluation display device 10. In this case, for example, similar to the use of a known ASP (Application Service Provider), the driving evaluation display device 10 may execute application software stored in the server 12 via the network N and evaluate the driving performance by a function realized by the application software. In this case, the driving evaluation display device 10 evaluates the driving performance by executing the application software based on the operation data received from the data logger 38. Alternatively, the driving performance may be evaluated by the driving evaluation display device 10 by executing a program stored in advance in the driving evaluation display device 10.

[0050] The display control unit 64 displays the evaluation results acquired by the evaluation acquisition unit 62 on the display unit 23 mounted on the vehicle V. Specifically, while the vehicle V is traveling, the display control unit 64 displays an evaluation image 70 (see FIG. 5) showing the evaluation results using a graphic image 72. This evaluation image is capable of displaying the evaluation results for each operation most recently performed by the driver.

[0051] The display mode of the evaluation image 70 will be specifically described with reference to the example shown in Fig. 5. The example in this figure shows the evaluation result for the driver's accelerator operation. The evaluation image 70 displays a circular graphic image 72 in the center of the display screen, and presents the evaluation result to the driver by changing the color and shape of the graphic image 72. Note that while Fig. 5 shows the graphic image 72 as a three-dimensional spherical image, it may also be a flat circular image.

[0052] Specifically, as shown in the upper diagram of Fig. 5, when the start of accelerator operation by the driver is detected while the vehicle is running, the evaluation image 70 displays a graphic image 72 in the center of the display screen in conjunction with the start of the operation. This allows the driver looking at the display unit 23 to intuitively understand that the accelerator operation that was most recently started is being evaluated. Note that, in the example of the embodiment, the graphic image 72 is displayed in an inconspicuous gray tone until the evaluation result of the driving operation is reflected.

[0053] Next, the display control unit 64 intuitively presents the evaluation result to the driver by changing the color and shape of the graphic image 72 based on the acquired evaluation result. Specifically, as shown in the center diagram of Fig. 5, when the evaluation result is "OK", the circular graphic image 72 is displayed in a state approximating a new circle, and the graphic image is displayed in a blue color tone. In addition, in this embodiment, text information of "Good Accelerator", which indicates that the accelerator operation is good, is displayed below the graphic image 72.

[0054] On the other hand, as shown in the lower diagram of Fig. 5, when the evaluation result is "NG judgement", the shape of the circular graphic image 72 is distorted and flattened, and the graphic image 72 is displayed in a yellow color tone. In this embodiment, text information of "Bad Accelerator", which indicates that the accelerator operation is poor, is displayed below the graphic image 72. The magnitude of the distortion of the graphic image 72 may be changed so as to increase as the number of "poor" evaluations counted during driving in a predetermined section increases.

[0055] Similarly, the evaluation image for the braking operation can indicate "good" or "bad" by changing the color and shape of the graphic image 72.

[0056] Although not shown in the figure, the evaluation result of "danger judgment" is calculated when a sudden start, sudden acceleration, sudden braking, or sudden stop occurs to a degree that threatens the safe driving of the vehicle V. In this case, the evaluation image 70 is displayed, for example, by emphasizing the display mode of the graphic image 72 compared to the display of other evaluation results, to call the driver's attention. For example, the graphic image 72 may be enlarged over time to give a visual effect of approaching the driver, and the graphic image 72 may be displayed in a red color tone.

[0057] In this way, the driver can intuitively recognize the evaluation result of his driving operation by the change in color and shape of the graphic image 72.

[0058] As shown in FIG. 6, the display control unit 64 displays an evaluation distribution image 80 when the driving state of the vehicle V changes from driving to stopped. The evaluation distribution image 80 shows the distribution of evaluation results for a plurality of driving operations during driving in a predetermined section, and includes a plurality of circular graphic images 82 shown in different colors corresponding to the evaluation results. In one example of this embodiment, a graphic image 82A showing an "OK judgment" is shown in a blue color tone, a graphic image 82B showing an "NG judgment" is shown in a yellow color tone, and a graphic image 82C showing a "danger judgment" is shown in a red color tone. Next to each graphic image 82, the number of times each evaluation result was calculated with respect to the total number of evaluations in the predetermined section is presented by text information. For example, according to FIG. 6, it can be seen that the evaluation of the accelerator operation was performed 40 times in the predetermined section, and of those, the evaluation result showing an "OK judgment" was calculated 20 times. In this way, the driver can quantitatively and objectively grasp the tendency of his / her driving operation in the predetermined section while the vehicle is stopped, which makes it easier to encourage improvement of the driving operation when driving is resumed thereafter.

[0059] The specified section may be, for example, the section from the most recent start of the vehicle V to when it is stopped, or the section during which the vehicle V travels a specified distance from when it starts, or the section traveled between when the engine is started and when it is stopped.

[0060] (Action and Effects) As described above, in the driving evaluation display device 10 of this embodiment, the evaluation result of the driver's driving operation is displayed as an evaluation image on the display unit 23. At this time, the evaluation image 70 is displayed in conjunction with the start of the driving operation by the driver, and at least a part of the display mode changes based on the evaluation result of the driving operation.

[0061] Specifically, in this embodiment, the evaluation image 70 is a graphic image 72, and the shape of the evaluation image 70 is distorted and displayed based on the obtained evaluation result (see FIG. 5).

[0062] As a result, when the driver starts the driving operation to be evaluated, the evaluation image 70 is displayed in time with the timing at which the driver feels the operation, so that the driver can intuitively understand the driving operation to be evaluated. Also, by changing the display mode of the evaluation image 70 based on the evaluation result, the evaluation result according to the operation feeling can be displayed in a manner that makes it easy to intuitively understand.

[0063] In this embodiment, when the driving state of the vehicle changes from running to stopped, an evaluation distribution image 80 is displayed on the display unit (see FIG. 6). This evaluation distribution image 80 shows the distribution of evaluation results for multiple driving operations in a specified section. As a result, the evaluation distribution for multiple driving operations in the section to be evaluated is presented to the driver while the vehicle is stopped, which does not interfere with driving operations. As a result, the driver can objectively grasp the tendency of his / her driving operation and make improvements.

[0064] [supplementary explanation] Although the driving evaluation display device 10 according to the embodiment has been described above, it goes without saying that the present invention can be embodied in various forms without departing from the gist of the present invention.

[0065] (Modifications of evaluation image and evaluation distribution image) For example, in the above embodiment, the display mode in which the judgment result is conveyed to the driver by distorting the shape of the graphic image has been described, but the present invention is not limited to this. As shown in the upper and central diagrams of FIG. 7, the evaluation image 90 may be displayed as a circular graphic image 92, and the color of the outer periphery 92A of the graphic image 92 may be changed based on the evaluation result to inform the driver of the evaluation result. In this example, when an "OK judgment" is calculated for the driver's driving operation, the outer periphery 92A of the graphic image 92 is displayed in a blue color tone. On the other hand, when an "NG judgment" is calculated for the driver's driving operation, the outer periphery 92A of the graphic image 92 is displayed in a yellow color tone.

[0066] Also, as shown in the lower diagram of FIG. 7, in the modified example, when the driving state of the vehicle changes from running to stopped, the distribution of the evaluation results for multiple driving operations in a predetermined section is displayed using an evaluation distribution image 100 consisting of a gradation image. In FIG. 7, a gradation image including a display area X displaying a blue color tone indicating an "OK judgment", a display area Y displaying a yellow color tone indicating an "NG judgment", and a display area Z displaying a red color tone indicating a "dangerous judgment" is presented on the display unit 23 as the evaluation distribution image 100. The size of each display area is displayed to be larger in proportion to the count number of each evaluation. Therefore, according to FIG. 7, since the display area X has the largest display area, it can be intuitively known that the number of "OK judgments" is the largest for the evaluation of a predetermined driving operation in the predetermined section.

[0067] In the above embodiment, the accelerator operation and the brake operation are evaluated, but the present invention is not limited to this. For example, the steering operation, the dangerous operation, the observance of traffic signals, the observance of signs, and other driving operations may be set as the operations to be evaluated.

[0068] Furthermore, the processing executed by the CPU 20 by reading the program in the above embodiment may be executed by various processors other than the CPU 20. Examples of the processor in this case include a PLD (Programmable Logic Device) whose circuit configuration can be changed after manufacture such as an FPGA (Field-Programmable Gate Array), and a dedicated electric circuit such as an ASIC (Application Specific Integrated Circuit) which is a processor having a circuit configuration designed exclusively for executing a specific processing. The above processing may be executed by one of these various processors, or may be executed by a combination of two or more processors of the same or different types, for example, by a plurality of FPGAs, or a combination of a CPU and an FPGA. The hardware structure of these various processors is, more specifically, an electric circuit that combines circuit elements such as semiconductor elements.

[0069] In the above embodiment, various data is stored in the storage 26, but the present invention is not limited to this. For example, a non-transitory recording medium such as a CD (Compact Disk), a DVD (Digital Versatile Disk), or a USB (Universal Serial Bus) memory may be used as the storage unit. In this case, various programs and data are stored in these recording media. [Explanation of symbols]
