[0001] The present disclosure relates to an information processing device. [Background technology]

[0002] Patent Document 1 discloses a technique for displaying an entire image of a speedometer on a display so that the display magnification of numbers and scales close to the indicated value indicated by the needle is increased. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-266288 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the technology described in Patent Document 1, the area in which the display magnification increases in the overall image of the speedometer constantly changes in response to changes in vehicle speed, making the displayed content bothersome to the driver.

[0005] Therefore, an object of the present disclosure is to provide an information processing device that can improve the visibility of an instrument image of an instrument that shows vehicle information related to vehicle driving control displayed on a display unit. [Means for solving the problem]

[0006] The information processing device of claim 1 displays an instrument image of an instrument showing vehicle information related to vehicle driving control on a display unit, and includes a control unit that changes the intervals of the scales of the instrument shown in the instrument image depending on the state of the vehicle.

[0007] In the information processing device according to claim 1, the control unit displays an instrument image of an instrument showing vehicle information related to vehicle driving control on the display unit. The control unit then changes the intervals of the scales of the instrument shown on the instrument image depending on the state of the vehicle. As a result, according to the information processing device, the scales are displayed at intervals according to the state of the vehicle, thereby improving the visibility of the instrument image in a specific state.

[0008] In the information processing device of claim 2, in claim 1, the vehicle information is engine speed, and when the vehicle is in a sports mode that performs driving control suitable for sports driving, the control unit widens the intervals of the scale in the high rotation speed range of the engine speed in the instrument image compared to the intervals of the scale in the low rotation speed range.

[0009] In the information processing device according to claim 2, the vehicle information is engine speed. When the vehicle is in a sports mode that performs driving control suitable for sports driving, the control unit widens the intervals of the scale markings in the high engine speed range on the instrument image compared to the intervals of the scale markings in the low engine speed range. This allows the information processing device to improve the visibility of the instrument image in sports mode by widening the intervals of the scale markings corresponding to the high engine speed range that the driver focuses on during sports driving.

[0010] The information processing device according to claim 3 is the same as claim 1 or 2, wherein the vehicle information is engine speed, and when the vehicle is located in a specific location where sporty driving is possible, the control unit widens the intervals of the scales in the high engine speed range in the instrument image compared to the intervals of the scales in the low engine speed range.

[0011] In the information processing device according to claim 3, the vehicle information is engine speed. When the vehicle is located in a specific location where sporty driving is possible, the control unit widens the intervals of the scales in the high engine speed range on the instrument image compared to the intervals of the scales in the low engine speed range. This allows the information processing device to improve the visibility of the instrument image in the specific location by automatically widening the intervals of the scales corresponding to the high engine speed range in response to the driver's intention.

[0012] The information processing device of claim 4 is any one of claims 1 to 3, wherein the vehicle information is engine speed, and when the vehicle is in an eco mode that performs driving control suitable for eco-driving, the control unit widens the intervals of the scale in the low engine speed range on the instrument image compared to the intervals of the scale in the high engine speed range.

[0013] In the information processing device according to claim 4, the vehicle information is engine speed. When the vehicle is in eco mode, which performs driving control suitable for eco-driving, the control unit widens the intervals of the scale markings in the low engine speed range on the instrument image compared to the intervals of the scale markings in the high engine speed range. This allows the information processing device to improve the visibility of the instrument image in eco mode by widening the intervals of the scale markings corresponding to the low engine speed range on which the driver focuses during eco-driving.

[0014] The information processing device of claim 5 is any one of claims 1 to 4, wherein when the control unit widens the interval between the scale marks in a predetermined part shown on the instrument image, the control unit narrows the interval between the scale marks in other parts to maintain the display size of the instrument image on the display unit.

[0015] In the information processing device according to claim 5, when the interval between the scale marks in a predetermined portion shown on the instrument image is widened, the control unit narrows the interval between the scale marks in other portions to maintain the display size of the instrument image on the display unit. As a result, the information processing device can prevent the display size of the instrument image from being changed in accordance with a change in the interval between the scale marks, and prevent the display content on the display unit from becoming bothersome to the driver. [Effects of the Invention]

[0016] As described above, the information processing device according to the present disclosure can improve the visibility of the instrument image of the instrument that shows vehicle information related to vehicle driving control displayed on the display unit. [Brief explanation of the drawings]

[0018] The vehicle 10 according to this embodiment will be described below. (First embodiment) First, a first embodiment of a vehicle 10 according to the present embodiment will be described.

[0019] Fig. 1 is a block diagram showing the hardware configuration of a vehicle 10. As shown in Fig. 1, the vehicle 10 includes a meter ECU (Electronic Control Unit) 20. The meter ECU 20 is an example of an "information processing device."

[0020] The meter ECU 20 includes a CPU (Central Processing Unit) 21, a ROM (Read Only Memory) 22, a RAM (Random Access Memory) 23, a storage 24, an in-vehicle communication I / F (Interface) 25, an input / output I / F 26, and a wireless communication I / F 27. The CPU 21, the ROM 22, the RAM 23, the storage 24, the in-vehicle communication I / F 25, the input / output I / F 26, and the wireless communication I / F 27 are connected to each other via an internal bus 28 so as to be able to communicate with each other.

[0021] The CPU 21 is a central processing unit that executes various programs and controls each part. That is, the CPU 21 reads programs from the ROM 22 or the storage 24 and executes the programs using the RAM 23 as a work area. The CPU 21 controls each of the above components and performs various arithmetic processing in accordance with the programs recorded in the ROM 22 or the storage 24.

[0022] The ROM 22 stores various programs and various data. The RAM 23 serves as a working area for temporarily storing programs or data.

[0023] The storage 24 is configured with a storage device such as an eMMC (embedded multi media card) or a UFS (universal flash storage), and stores various programs and various data. An information processing program 24A is stored in the storage 24. The information processing program 24A is a program for causing the CPU 21 to execute specific processing (see FIG. 3), which will be described later.

[0024] The in-vehicle communication I / F 25 is an interface for connecting to other ECUs 30. The interface uses a communication standard based on the CAN protocol. The in-vehicle communication I / F 25 is connected to an external bus 29. Although not shown, in addition to the ECU 30, multiple ECUs are provided for each function of the vehicle 10.

[0025] The input / output I / F 26 is an interface for communicating with an in-vehicle device 40 mounted on the vehicle 10 .

[0026] The on-vehicle devices 40 are various devices mounted on the vehicle 10. The vehicle 10 includes, as examples of the on-vehicle devices 40, a group of sensors 42, a monitor 44, and a group of switches 46.

[0027] The sensor group 42 includes sensors for detecting the state of the vehicle 10 and the surrounding circumstances, such as a 3D-LiDAR, a millimeter wave sensor, an infrared sensor, a blinker sensor, an accelerator position sensor, a vehicle speed sensor, a steering angle sensor, an angular velocity sensor, a GPS (Global Positioning System) sensor, an illuminance sensor, a gyro sensor, and an acceleration sensor. The sensor group 42 outputs the detection results of each sensor to the meter ECU 20, the ECU 30, etc.

[0028] The monitor 44 is provided on an instrument panel located in front of the driver's seat of the vehicle 10, and is a liquid crystal monitor for displaying operation suggestions related to the functions of the vehicle 10 and images related to explanations of the functions. The monitor 44 is an example of a "display unit."

[0029] The switch group 46 includes various switches for activating or deactivating functions of the vehicle 10. The switch group 46 outputs operation details of the various switches to the meter ECU 20, the ECU 30, and the like.

[0030] The wireless communication I / F 27 is a wireless communication module for communicating with external devices, and uses communication standards such as 5G, LTE, Wi-Fi (registered trademark), and Bluetooth (registered trademark).

[0031] The CPU 21 of the meter ECU 20 has, as functional components, an acquisition unit 21A and a control unit 21B. Each functional component is realized by the CPU 21 reading and executing an information processing program 24A stored in the storage 24.

[0032] The acquisition unit 21A acquires various types of information. For example, the acquisition unit 21A acquires, as the various types of information, data input from the ECU 30 via the in-vehicle communication I / F 25, data input from the sensor group 42 or the switch group 46 via the input / output I / F 26, and the like.

[0033] The control unit 21B performs display control regarding the display on the monitor 44. For example, as the display control, the control unit 21B displays, on the monitor 44, an instrument image 54 (see FIG. 2, etc.) of an instrument indicating vehicle information regarding driving control of the vehicle 10. The vehicle information includes the engine speed, vehicle speed, etc.

[0034] Fig. 2 shows a first display example displayed on the monitor 44. Specifically, Fig. 2 shows a display example of an instrument image 54 when the vehicle 10 is in normal mode.

[0035] Here, vehicle 10 has three driving modes: a normal mode, which is a normal driving mode; an eco mode, which realizes eco-driving that prioritizes fuel efficiency more than in the normal mode; and a sport mode, which allows for more powerful sport driving than in the normal mode. The driver can switch between driving modes by operating a predetermined switch included in switch group 46. In the sport mode, driving control suitable for sport driving is performed, and for example, the torque required of the engine based on the accelerator opening detected by the accelerator position sensor included in sensor group 42 is greater than in the normal mode. In the eco mode, driving control suitable for eco-driving is performed, and for example, the torque required of the engine based on the accelerator opening is smaller than in the normal mode.

[0036] As shown in FIG. 2, the monitor 44 displays vehicle speed information 50, shift information 52, an instrument image 54, and a gauge 56.

[0037] The vehicle speed information 50 indicates the speed of the vehicle 10. In Fig. 2, "68 km / h" is displayed as the vehicle speed information 50, indicating that the vehicle speed is 68 km / h.

[0038] The shift information 52 indicates the shift position of the vehicle 10. In Fig. 2, "D" is displayed as the shift information 52, indicating that the shift position is in the D range.

[0039] The instrument image 54 is an image of a tachometer, which is an instrument that indicates engine speed. The instrument image 54 has eight scales 54A and numerical values ​​54B that indicate the engine speed corresponding to each of the scales 54A. In the instrument image 54, the intervals between the eight scales 54A are all equal.

[0040] The gauge 56 is a rectangular shape that expands and contracts in response to changes in engine speed. In Fig. 2, the gauge 56 is located near the front end of the scale 54A, which is the fourth mark from the left, indicating that the engine speed is approximately 3000 revolutions per minute.

[0041] Here, the CPU 21 of the meter ECU 20, as a function of the control unit 21B, changes the intervals of the tachometer scale 54A shown on the instrument image 54 in accordance with the state of the vehicle 10. The state of the vehicle 10 is a concept that includes the driving mode and driving location of the vehicle 10. Hereinafter, the flow of the control by the meter ECU 20 will be described with reference to FIG. 3.

[0042] 3 is a flowchart showing the flow of the identification process executed by the meter ECU 20. The CPU 21 reads the information processing program 24A from the storage 24, loads it into the RAM 23, and executes it, thereby performing the identification process. As an example, the identification process is automatically and repeatedly performed at regular intervals when the driving mode of the vehicle 10 is the normal mode.

[0043] 3, the CPU 21 acquires various pieces of information, and then the CPU 21 proceeds to step S11.

[0044] In step S11, the CPU 21 determines whether or not a change condition for changing the interval of the tachometer scale 54A shown on the instrument image 54 is met. If the CPU 21 determines that the change condition is met (step S11: YES), the CPU 21 proceeds to step S12. On the other hand, if the CPU 21 determines that the change condition is not met (step S11: NO), the CPU 21 returns to step S10. In the first embodiment, the CPU 21 determines that the change condition is met when the driving mode is switched to the eco mode or the sport mode.

[0045] In step S12, the CPU 21 changes the intervals of the tachometer scale 54A shown on the instrument image 54 in accordance with the state of the vehicle 10. In the first embodiment, the CPU 21 changes the instrument image 54 to an interval of the scale 54A that corresponds to whether the driving mode is the sport mode or the eco mode. Then, the CPU 21 ends the specification process.

[0046] Next, an example of changing the intervals of the scale 54A will be described with reference to FIGS. Fig. 4 shows a second display example displayed on the monitor 44. Specifically, Fig. 4 shows a first display example of an instrument image 54 when the vehicle 10 is in the sport mode.

[0047] As shown in FIG. 4, the monitor 44 displays vehicle speed information 50, shift information 52, an instrument image 54, and a gauge 56.

[0048] In Fig. 4, "80 km / h" is displayed as vehicle speed information 50, indicating that the vehicle speed is 80 km / h. Also in Fig. 4, "D" is displayed as shift information 52, indicating that the shift position is in the D range. Also in Fig. 4, gauge 56 is located near the front end of scale 54A, the seventh mark from the left, indicating that the engine speed is approximately 6,000 revolutions per minute.

[0049] 4, the intervals between the scale marks 54A corresponding to the high rotational speed range of the engine, where the rotational speed is 4000 rotations per minute or more, are wider than the intervals between the scale marks 54A corresponding to the low rotational speed range of less than 4000 rotations per minute. As an example, the intervals between the scale marks 54A become wider as the rotational speed range becomes higher in the instrument image 54. For example, in the instrument image 54, the intervals between the scale marks 54A sixth from the left, which indicates 5000 to 6000 rotations per minute, are wider than the intervals between the scale marks 54A fifth from the left, which indicates 4000 to 5000 rotations per minute.

[0050] Fig. 5 shows a third display example displayed on the monitor 44. Specifically, Fig. 5 shows a display example of an instrument image 54 when the vehicle 10 is in the eco mode.

[0051] As shown in FIG. 5, the monitor 44 displays vehicle speed information 50, shift information 52, an instrument image 54, and a gauge 56.

[0052] In Fig. 5, "30 km / h" is displayed as vehicle speed information 50, indicating that the vehicle speed is 30 km / h. Also in Fig. 5, "D" is displayed as shift information 52, indicating that the shift position is in D range. Also in Fig. 5, gauge 56 is located near the front end of scale 54A, the second mark from the left, indicating that the engine speed is approximately 1000 revolutions per minute.

[0053] 5, the intervals between the scale marks 54A corresponding to the low rotational speed range where the engine speed is less than 4000 rotations per minute are wider than the intervals between the scale marks 54A corresponding to the high rotational speed range where the engine speed is 4000 rotations per minute or higher. As an example, in the instrument image 54, the intervals between the scale marks 54A become wider as the rotational speed range becomes lower. For example, in the instrument image 54, the intervals between the scale marks 54A second from the left, which indicates 1000 to 2000 rotations per minute, are wider than the intervals between the scale marks 54A third from the left, which indicates 2000 to 3000 rotations per minute.

[0054] 4 and 5, when the intervals between the scale marks 54A in a predetermined portion shown on the instrument image 54 are widened, the CPU 21 narrows the intervals between the scale marks 54 in other portions to maintain the display size of the instrument image 54 on the monitor 44. For example, in FIG. 4, the CPU 21 narrows the intervals between the scale marks 54A in other portions corresponding to the low rotation range by the amount that the intervals between the scale marks 54A corresponding to the high rotation range, which is the predetermined portion, are widened. In this case, the CPU 21 narrows the intervals between the scale marks 54A as the rotation range becomes lower. For example, in the instrument image 54 shown in FIG. 4, the interval between the second scale mark 54A from the left, which indicates 1000 to 2000 rotations per minute, is narrower than the interval between the third scale mark 54A from the left, which indicates 2000 to 3000 rotations per minute.

[0055] As described above, in the meter ECU 20, the CPU 21 displays the instrument image 54 of a tachometer indicating the engine speed on the monitor 44. The CPU 21 then changes the intervals of the tachometer scale 54A shown on the instrument image 54 in accordance with the state of the vehicle 10. As a result, the meter ECU 20 displays the scale 54A at intervals according to the state of the vehicle 10, thereby improving the visibility of the instrument image 54 in a specific state.

[0056] Furthermore, in the meter ECU 20, as a function of the control unit 21B, the CPU 21 widens the intervals of the scales 54A in the high engine speed range compared to the intervals of the scales 54A in the low engine speed range on the instrument image 54 when the vehicle 10 is in the sport mode. As a result, the meter ECU 20 widens the intervals of the scales 54A corresponding to the high engine speed range that the driver focuses on during sport driving, thereby improving the visibility of the instrument image 54 in the sport mode.

[0057] Furthermore, in the meter ECU 20, as a function of the control unit 21B, the CPU 21 widens the intervals of the scales 54A in the low engine speed range compared to the intervals of the scales 54A in the high engine speed range in the instrument image 54 when the vehicle 10 is in the eco mode. As a result, the meter ECU 20 widens the intervals of the scales 54A corresponding to the low engine speed range that the driver focuses on during eco-driving, thereby improving the visibility of the instrument image 54 in the eco mode.

[0058] Furthermore, in the meter ECU 20, when the intervals between the scale marks 54A in a predetermined portion shown on the instrument image 54 are widened, the CPU 21 narrows the intervals between the scale marks 54A in other portions to maintain the display size of the instrument image 54 on the monitor 44. As a result, the meter ECU 20 can prevent the display size of the instrument image 54 from being changed in accordance with a change in the intervals between the scale marks 54A, and can prevent the display content of the monitor 44 from becoming bothersome to the driver.

[0059] (Second embodiment) Next, a second embodiment of the vehicle 10 according to the present invention will be described while omitting or simplifying parts that overlap with the above embodiment.

[0060] The second embodiment differs from the above-described embodiment in the determination of whether the change condition is met in the specific processing shown in Fig. 3. Specifically, in step S11 shown in Fig. 3, the CPU 21 determines that the change condition is met when the driving mode is switched to the eco mode or the sport mode, or when the current location of the vehicle 10 measured by the GPS sensor included in the sensor group 42 belongs to a specific location. The specific location is, for example, a place where motorsports are held, such as a circuit or rally course, where sports driving is possible, in which the vehicle 10 is driven at an increased speed at which the speed limiter of the vehicle 10 is activated.

[0061] Then, when the vehicle 10 is located in a specific location where sporty driving is possible, the CPU 21, as a function of the control unit 21B, widens the intervals of the scales 54A in the high engine speed range on the instrument image 54 compared to the intervals of the scales 54A in the low engine speed range (see FIG. 4). As a result, the meter ECU 20 automatically widens the intervals of the scales 54A corresponding to the high engine speed range in response to the driver's intention, thereby improving the visibility of the instrument image 54 in the specific location.

[0062] (others) In the above embodiment, the CPU 21 may display different content for the scale 54A with wider intervals and the scale 54A with narrower intervals, thereby improving the visibility of the scale 54A with wider intervals. This will be explained below with reference to FIG. 6.

[0063] Fig. 6 shows a fourth display example displayed on the monitor 44. Specifically, Fig. 6 shows a second display example of the instrument image 54 when the vehicle 10 is in the sports mode.

[0064] In the instrument image 54 shown in FIG. 6 , similar to the above embodiment, the intervals between the scale marks 54A corresponding to the high rotation speed range (4000 rpm or more) are wider than the intervals between the scale marks 54A corresponding to the low rotation speed range (less than 4000 rpm). Here, in the instrument image 54, the scale marks 54A corresponding to the high rotation speed range are hatched with diagonal lines, and the scale marks 54A corresponding to the low rotation speed range are left blank. In this manner, the CPU 21 may highlight the widely spaced scale marks 54A by hatching only the widely spaced scale marks 54A to enhance their visibility. The highlighting method is not limited to a difference in the design of the scale marks 54A, and may also be a difference in the color of the scale marks 54A, for example.

[0065] In the above embodiment, the monitor 44 is an example of the "display unit," but the example of the "display unit" is not limited to this. For example, the "display unit" may be a multimedia display provided above the center console or a head-up display (HUD). When the "display unit" is a display other than the monitor 44, an example of the information processing device is an ECU that controls the other display.

[0066] In the above embodiment, the tachometer is used as an example of an "instrument," but the example of the "instrument" is not limited to this. For example, the "instrument" may be a speedometer that indicates vehicle speed. In this case, the instrument image is an image of the speedometer that indicates vehicle speed.

[0067] In the above embodiment, the engine speed was defined as a high rotation range of 4000 rpm or more and a low rotation range of less than 4000 rpm, but the boundary between the high rotation range and the low rotation range is not limited to this and can be set to any numerical value.

[0068] In the above embodiment, the intervals between the markings 54A in the instrument image 54 become wider as the rotation speed increases and narrower as the rotation speed decreases, but this is not limited to this. For example, in the instrument image 54, the intervals between the markings 54A in the high rotation speed range may be wider and uniform than in the low rotation speed range, and the intervals between the markings 54A in the low rotation speed range may be narrower and uniform than in the high rotation speed range.

[0069] In the above embodiment, the CPU 21 may determine that a change condition is met when, for example, a predetermined input is received to increase the vehicle speed at which the speed limiter of the vehicle 10 is activated in order to change the driving performance of the vehicle 10. In this case, the CPU 21 may widen the intervals of the scales 54A corresponding to the high rotation speed range of the engine speed in the instrument image 54 based on the meeting of the change condition.

[0070] In the above embodiment, the design of the instrument image 54 is the same regardless of the driving mode of the vehicle 10, but the design of the instrument image 54 may be different for each driving mode. For example, the shape or color of the scale 54A may be different for each driving mode. Similarly, the design of the gauge 56 may be different for each driving mode. For example, the shape or color of the gauge 56 may be different for each driving mode.

[0071] In the above embodiment, the number of scales 54A is the same regardless of the driving mode of the vehicle 10, but this is not limitative, and the number of scales 54A may be different for each driving mode.

[0072] In the above embodiment, when the spacing between the scale marks 54A in a predetermined portion shown on the instrument image 54 is widened, the spacing between the scale marks 54A in all other remaining portions is narrowed, but this is not limiting. For example, when the spacing between the scale marks 54A in a predetermined portion on the instrument image 54 is widened, there may be scale marks 54A in certain other portions where the spacing between the scale marks 54A does not narrow.

[0073] In the above embodiment, the specific process executed by the CPU 21 after reading the software (program) may be executed by various processors other than a CPU. Examples of such processors include programmable logic devices (PLDs) (such as field-programmable gate arrays (FPGAs)) whose circuit configuration can be changed after fabrication, and dedicated electrical circuits such as application-specific integrated circuits (ASICs) that are processors with circuit configurations specifically designed to execute specific processes. The specific process may be executed by one of these processors, or by a combination of two or more processors of the same or different types (e.g., multiple FPGAs, or a combination of a CPU and an FPGA). The hardware structure of these processors is, more specifically, an electrical circuit that combines circuit elements such as semiconductor devices.

[0074] In the above embodiment, the information processing program 24A is pre-stored (installed) in the storage 24, but the present invention is not limited to this. The information processing program 24A may be provided in a form recorded on a recording medium such as a CD-ROM (Compact Disk Read Only Memory), a DVD-ROM (Digital Versatile Disk Read Only Memory), or a USB (Universal Serial Bus) memory. The information processing program 24A may also be downloaded from an external device via a network. [Explanation of symbols]
