[0027] Hereinafter, in order to explain the present invention in more detail, the mode for carrying out the present invention will be described with reference to the drawings.

[0028] Implementation Method 1

[0029] Figure 1 1 is a diagram showing the structure of the display control device 3 according to the first embodiment.

[0030] Figure 2 This is a hardware configuration diagram showing the hardware of the display control device 3 according to the first embodiment.

[0031] The brake pedal sensor 1 monitors the operation of the brake pedal of the vehicle, and outputs brake pedal operation information indicating whether the driver has depressed the brake pedal to the display control device 3 .

[0032] The accelerator pedal sensor 2 monitors the operation of the accelerator pedal of the vehicle, and outputs accelerator pedal operation information indicating whether the driver has depressed the accelerator pedal to the display control device 3 .

[0033] The display control device 3 causes an instrument panel (hereinafter referred to as “instrument panel”) 4 of the vehicle to display a speedometer, a tachometer, a fuel gauge, a water temperature gauge, a rangefinder, or the like.

[0034] The display control device 3 notifies the driver of the vehicle whether or not a pedal operation has been performed by the driver, without providing a dedicated display area on the instrument panel 4 of the vehicle.

[0035] When the display area of ​​the instrument panel 4 is limited, for example, when a dedicated display area for displaying the character "brake" is set on the instrument panel 4 of the vehicle, the area for displaying other information becomes relatively narrow, and it is difficult for the driver to confirm other information. The display control device 3 does not need to set a dedicated display area on the instrument panel 4 of the vehicle, so the area for displaying other information will not become relatively narrow.

[0036] The instrument panel 4 is an instrument panel provided at the driver's seat of the vehicle, and displays a speedometer, a tachometer, a fuel gauge, a water temperature gauge, a rangefinder, and the like.

[0037] exist Figure 1 In the illustrated display control device 3 , it is assumed that the instrument panel 4 is a so-called digital instrument, but it may be an analog instrument.

[0038] Figure 1 The display control device 3 shown includes a pedal operation detection unit 11 and a display mode switching unit 12 .

[0039] The pedal operation detection unit 11 is composed of, for example, Figure 2 The pedal operation detection circuit 21 shown is implemented.

[0040] The pedal operation detection unit 11 acquires brake pedal operation information from the brake pedal sensor 1 , and acquires accelerator pedal operation information from the accelerator pedal sensor 2 .

[0041] The pedal operation detection unit 11 detects a pedal operation of the vehicle.

[0042] That is, if the brake pedal operation information indicates that the driver is performing a brake pedal depression operation, the pedal operation detection unit 11 detects the operation of the brake pedal.

[0043] If the accelerator pedal operation information indicates that the driver is depressing the accelerator pedal, the pedal operation detection unit 11 detects the operation of the accelerator pedal.

[0044] The pedal operation detection unit 11 outputs the detection result of the pedal operation to the display mode switching unit 12 .

[0045] The display mode switching unit 12 is composed of, for example, Figure 2 The display mode switching circuit 22 shown is implemented.

[0046] The display mode switching unit 12 causes the instrument panel 4 to display a speedometer, a tachometer, a fuel gauge, a water temperature gauge, a distance meter, or the like.

[0047] The display mode switching unit 12 switches the display mode of the instrument displayed on the instrument panel 4 and the instrument that is associated with the pedal operation and the reminder information, based on the detection result of the pedal operation by the pedal operation detection unit 11 .

[0048] As a meter that associates the pedal operation with the prompt information, a speedometer or a tachometer may be considered.

[0049] Therefore, the display mode switching unit 12 switches the display mode of the speedometer or the display mode of the tachometer according to the detection result of the pedal operation by the pedal operation detection unit 11 .

[0050] exist Figure 1 In the embodiment, it is assumed that the pedal operation detection unit 11 and the display mode switching unit 12 as components of the display control device 3 are respectively Figure 2 Specifically, it is assumed that the display control device 3 is implemented by the pedal operation detection circuit 21 and the display mode switching circuit 22.

[0051] The pedal operation detection circuit 21 and the display mode switching circuit 22 are respectively equivalent to, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array) or a circuit combining them.

[0052] The components of the display control device 3 are not limited to those implemented by dedicated hardware, and the display control device 3 may be implemented by software, firmware, or a combination of software and firmware.

[0053] Software or firmware is stored as a program in a computer's memory. A computer is hardware that executes a program, such as a CPU (Central Processing Unit), a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, a processor, or a DSP (Digital Signal Processor).

[0054] Figure 3 This is a hardware configuration diagram of a computer when the display control device 3 is implemented by software, firmware, or the like.

[0055] When the display control device 3 is implemented by software or firmware, a program for causing a computer to execute each process step in the pedal operation detection unit 11 and the display mode switching unit 12 is stored in the memory 31. Then, the processor 32 of the computer executes the program stored in the memory 31.

[0056] In addition, Figure 2 In FIG. 1 , an example is shown in which the components of the display control device 3 are respectively implemented by dedicated hardware. Figure 3 , an example is shown in which the display control device 3 is implemented by software or firmware. However, this is just an example, and some components of the display control device 3 may be implemented by dedicated hardware, and the remaining components may be implemented by software or firmware.

[0057] Next, explain Figure 1 The operation of the display control device 3 is shown.

[0058] Figure 4 This is a flowchart showing a display control method as a processing procedure of the display control device 3 according to the first embodiment.

[0059] The brake pedal sensor 1 monitors the operation of the brake pedal of the vehicle.

[0060] When the driver performs a brake pedal depression operation, the brake pedal sensor 1 outputs brake pedal operation information indicating that the driver performs a brake pedal depression operation to the pedal operation detection unit 11 of the display control device 3 .

[0061] If the driver does not perform a depression operation on the brake pedal, the brake pedal sensor 1 outputs brake pedal operation information indicating that the driver does not perform a depression operation to the pedal operation detection unit 11 .

[0062] The accelerator pedal sensor 2 monitors the operation of the accelerator pedal of the vehicle.

[0063] If the driver is depressing the accelerator pedal, the accelerator pedal sensor 2 outputs accelerator pedal operation information indicating that the driver is depressing the accelerator pedal to the pedal operation detection unit 11 .

[0064] If the driver does not perform a depression operation on the accelerator pedal, the accelerator pedal sensor 2 outputs accelerator pedal operation information indicating that the driver does not perform a depression operation to the pedal operation detection unit 11 .

[0065] The pedal operation detection unit 11 obtains brake pedal operation information from the brake pedal sensor 1 and obtains accelerator pedal operation information from the accelerator pedal sensor 2 ( Figure 4 Step ST1).

[0066] If the brake pedal operation information indicates that the driver is depressing the brake pedal ( Figure 4 Step ST2: If “Yes”), the pedal operation detection unit 11 detects the operation of the brake pedal ( Figure 4 Step ST3).

[0067] If the brake pedal operation information indicates that the driver has not depressed the brake pedal ( Figure 4 In step ST2: In the case of "No", the pedal operation detection unit 11 does not detect the operation of the brake pedal.

[0068] When the operation of the brake pedal is not detected, if the accelerator pedal operation information indicates that the driver is depressing the accelerator pedal ( Figure 4 In step ST4: If “Yes”), the pedal operation detection unit 11 detects the operation of the accelerator pedal ( Figure 4 Step ST5).

[0069] If the accelerator pedal operation information indicates that the driver has not depressed the accelerator pedal ( Figure 4 In step ST4: "No", the pedal operation detection unit 11 does not detect the operation of the accelerator pedal. That is, the pedal operation detection unit 11 does not detect both the operation of the brake pedal and the operation of the accelerator pedal ( Figure 4 Step ST6).

[0070] The pedal operation detection unit 11 outputs the detection result of the pedal operation to the display mode switching unit 12 .

[0071] exist Figure 1 In the display control device 3 shown, it is assumed that the depressing operation of the brake pedal and the depressing operation of the accelerator pedal are not performed at the same time. When the pedal operation detection unit 11 does not detect the operation of the brake pedal, if the accelerator pedal operation information indicates that the driver is depressing the accelerator pedal, the operation of the accelerator pedal is detected. However, this is just an example, and even if the operation of the brake pedal is detected, if the accelerator pedal operation information indicates that the driver is depressing the accelerator pedal, the pedal operation detection unit 11 can also detect the operation of the accelerator pedal.

[0072] The display mode switching unit 12 causes the instrument panel 4 to display a speedometer, a tachometer, a fuel gauge, a water temperature gauge, a distance meter, or the like.

[0073] The display mode switching unit 12 switches the display mode of the instrument associated with the pedal operation and the prompt information displayed on the instrument panel 4 according to the detection result of the pedal operation by the pedal operation detection unit 11. Figure 4 Step ST7).

[0074] Hereinafter, the display mode switching process performed by the display mode switching unit 12 will be described in detail.

[0075] The display mode switching unit 12 obtains the pedal operation detection result from the pedal operation detecting unit 11 .

[0076] If the pedal operation detection result indicates that the brake pedal operation is detected, the display mode switching unit 12 causes the instrument panel 4 to display Figure 5 Speedometer shown.

[0077] Figure 5 It is an explanatory diagram showing the display mode of the speedometer when the operation of the brake pedal is detected.

[0078] exist Figure 5 The instrument panel 4 shown shows an eco meter (represented as "ECO" in the figure) indicating the degree of energy saving, a character "D" indicating that the gear position is the forward gear D, "50 km / h" indicating the speed of the vehicle, "123456 km" indicating the total driving distance of the vehicle (hereinafter referred to as "ODO"), and "345.6 km" indicating the trip distance of the vehicle (hereinafter referred to as "TRIP"). Obviously, "50 km / h", "123456 km" and "345.6 km" are just examples.

[0079] In addition, Figure 5On the illustrated instrument panel 4 , graphics for confirming the surroundings of the vehicle, which represent objects and the like existing around the vehicle, are displayed.

[0080] The plurality of dot graphics displayed in an arc shape around "50 km / h" are first speed display graphics indicating that the speed of the vehicle is "50 km / h".

[0081] The first speed display graphic, which is a collection of a plurality of dot graphics, indicates that the driver is operating the brake pedal. In other words, when the driver is operating the brake pedal, the display mode switching unit 12 causes the instrument panel 4 to display the first speed display graphic.

[0082] If the pedal operation detection result indicates that the accelerator pedal operation is detected, the display mode switching unit 12 causes the instrument panel 4 to display Figure 6 Speedometer shown.

[0083] Figure 6 It is an explanatory diagram showing the display mode of the speedometer when the operation of the accelerator pedal is detected.

[0084] exist Figure 6 The illustrated instrument panel 4 displays an eco meter, a character "D" indicating that the gear position is the drive gear D, "50 km / h" indicating the speed of the vehicle, "123456 km" indicating ODO, and "345.6 km" indicating TRIP.

[0085] In addition, Figure 6 On the instrument panel 4 shown, graphics for confirming the surroundings of the vehicle are displayed.

[0086] The plurality of bar-shaped graphics displayed in an arc shape around "50 km / h" are second speed display graphics indicating that the speed of the vehicle is "50 km / h".

[0087] The second speed display graphic, which is a set of a plurality of bar graphics, indicates that the driver is operating the accelerator pedal. In other words, when the driver is operating the accelerator pedal, the display mode switching unit 12 causes the instrument panel 4 to display the second speed display graphic.

[0088] If the pedal operation detection result indicates that neither the brake pedal operation nor the accelerator pedal operation is detected, the display mode switching unit 12 causes the instrument panel 4 to display Figure 7 Speedometer shown.

[0089] Figure 7 This is an explanatory diagram showing the display mode of the speedometer when neither the operation of the brake pedal nor the operation of the accelerator pedal is detected.

[0090] exist Figure 7The illustrated instrument panel 4 displays an eco meter, a character "D" indicating that the gear position is the drive gear D, "50 km / h" indicating the speed of the vehicle, "123456 km" indicating ODO, and "345.6 km" indicating TRIP.

[0091] In addition, Figure 7 On the instrument panel 4 shown, graphics for confirming the surroundings of the vehicle are displayed.

[0092] The curved graph displayed in an arc shape around "50 km / h" is a third speed display graph indicating that the speed of the vehicle is "50 km / h".

[0093] The third speed display graph as a curve graph indicates that the driver has neither operated the brake pedal nor the accelerator pedal. In other words, when the driver has neither operated the brake pedal nor the accelerator pedal, the display mode switching unit 12 causes the instrument panel 4 to display the third speed display graph.

[0094] exist Figure 1 In the display control device 3 shown, the display mode switching unit 12 switches the shape of the speed display graphic according to the detection result of the pedal operation by the pedal operation detection unit 11. However, this is just an example, and the display mode switching unit 12 may also switch the color of the speed display graphic according to the detection result of the pedal operation by the pedal operation detection unit 11, for example, or switch the color of "50 km / h" indicating the speed of the vehicle.

[0095] exist Figure 1 In the display control device 3 shown, the display mode switching unit 12 switches the display mode of the speedometer according to the detection result of the pedal operation by the pedal operation detection unit 11. However, this is just an example, and the display mode switching unit 12 may also switch the display mode of the tachometer according to the detection result of the pedal operation by the pedal operation detection unit 11.

[0096] Figure 8 It is an explanatory diagram showing the display mode of the tachometer when the operation of the brake pedal is detected.

[0097] exist Figure 8 The instrument panel 4 shown in the figure displays "3500 rpm" indicating the engine speed. Of course, "3500 rpm" is just an example.

[0098] The plurality of dot graphics displayed in an arc shape around "3500 rpm" is a first rotation speed display graphic indicating that the engine rotation speed is "3500 rpm".

[0099] The first rotation speed display graphic, which is a collection of a plurality of dot graphics, indicates that the driver is operating the brake pedal. In other words, when the driver is operating the brake pedal, the display mode switching unit 12 causes the instrument panel 4 to display the first rotation speed display graphic.

[0100] Fig. 9 It is an explanatory diagram showing the display mode of the tachometer when the operation of the accelerator pedal is detected.

[0101] exist Fig. 9 The instrument panel 4 shown displays “3500 rpm” indicating the engine speed.

[0102] The plurality of bar-shaped graphics displayed in an arc shape around "3500 rpm" are second rotation speed display graphics indicating that the engine rotation speed is "3500 rpm".

[0103] The second rotation speed display graphic, which is a collection of a plurality of bar graphics, indicates that the driver is operating the accelerator pedal. In other words, when the driver is operating the accelerator pedal, the display mode switching unit 12 causes the instrument panel 4 to display the second rotation speed display graphic.

[0104] Fig.10 This is an explanatory diagram showing the display mode of the tachometer when neither the operation of the brake pedal nor the operation of the accelerator pedal is detected.

[0105] exist Fig.10 The instrument panel 4 shown displays “3500 rpm” indicating the engine speed.

[0106] The curve graph displayed in an arc shape around "3500 rpm" is a third rotation speed display graph indicating that the engine rotation speed is "3500 rpm".

[0107] The third rotation speed display graph as a curve graph indicates that the driver has neither operated the brake pedal nor the accelerator pedal. In other words, when the driver has neither operated the brake pedal nor the accelerator pedal, the display mode switching unit 12 causes the instrument panel 4 to display the third rotation speed display graph.

[0108] In the above-mentioned first embodiment, the display control device 3 is configured to include: a pedal operation detection unit 11 that detects a pedal operation of the vehicle; and a display mode switching unit 12 that switches the display mode of the instrument that is displayed on the instrument panel 4 of the vehicle and that is associated with the pedal operation and prompt information, according to the detection result of the pedal operation by the pedal operation detection unit 11. Therefore, the display control device 3 can notify the driver of the vehicle whether the pedal operation is performed by the driver without providing a dedicated display area on the instrument panel 4 of the vehicle.

[0109] Implementation Method 2

[0110] In Embodiment 2, the following display control device 3 is described: when the detection result of the pedal operation by the pedal operation detection unit 11 changes, when the display mode before the detection result changes to the display mode after the detection result changes, the display mode switching unit 13 displays an animation indicating the transition of the display mode.

[0111] Fig.11 2 is a diagram showing the structure of a display control device 3 according to Embodiment 2. Fig.11 In, with Figure 1 The same reference numerals denote the same or corresponding parts, and thus their descriptions are omitted.

[0112] Fig.12 2 is a hardware configuration diagram showing the hardware of the display control device 3 according to the second embodiment. Fig.12 In, with Figure 2 The same reference numerals denote the same or corresponding parts, and thus their descriptions are omitted.

[0113] The display mode switching unit 13 is composed of, for example, Fig.12 The display mode switching circuit 23 shown is implemented.

[0114] The display mode switching unit 13 and Figure 1 Similarly, the display mode switching unit 12 shown in the figure causes the instrument panel 4 to display a speedometer, a tachometer, a fuel gauge, a water temperature gauge, a distance meter, or the like.

[0115] The display mode switching unit 13 and Figure 1 Similarly, the display mode switching unit 12 shown switches the display mode of the instrument displayed on the instrument panel 4 and the instrument associated with the pedal operation and the reminder information, based on the detection result of the pedal operation by the pedal operation detection unit 11 .

[0116] and Figure 1 Unlike the display mode switching unit 12 shown, when the detection result of the pedal operation by the pedal operation detection unit 11 changes, the display mode switching unit 13 displays an animation indicating the transition of the display mode when switching from the display mode before the detection result changes to the display mode after the detection result changes.

[0117] exist Fig.11 In the embodiment, it is assumed that the pedal operation detection unit 11 and the display mode switching unit 13 as components of the display control device 3 are respectively Fig.12 Specifically, it is assumed that the display control device 3 is implemented by the pedal operation detection circuit 21 and the display mode switching circuit 23.

[0118] The pedal operation detection circuit 21 and the display mode switching circuit 23 are respectively equivalent to, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a circuit combining these.

[0119] The components of the display control device 3 are not limited to those implemented by dedicated hardware, and the display control device 3 may be implemented by software, firmware, or a combination of software and firmware.

[0120] When the display control device 3 is implemented by software or firmware, a program for causing a computer to execute each processing step in the pedal operation detection unit 11 and the display mode switching unit 13 is stored in Figure 3 The memory 31 shown. And, Figure 3 The processor 32 shown executes the program stored in the memory 31 .

[0121] In addition, Fig.12 In FIG. 1 , an example is shown in which the components of the display control device 3 are respectively implemented by dedicated hardware. Fig.13 , an example is shown in which the display control device 3 is implemented by software or firmware. However, this is just an example, and some components of the display control device 3 may be implemented by dedicated hardware, and the remaining components may be implemented by software or firmware.

[0122] Next, explain Fig.11 The operation of the display control device 3 is shown.

[0123] However, except for the display mode switching unit 13, Figure 1 The display control device 3 shown is the same, and therefore, the operation of the display mode switching unit 13 will be mainly described here.

[0124] The pedal operation detection unit 11 repeatedly performs a process of detecting a pedal operation of the vehicle, and repeatedly outputs the detection result of the pedal operation to the display mode switching unit 13 .

[0125] Every time the pedal operation detection result is received from the pedal operation detection unit 11 , the display mode switching unit 13 switches the display mode of the meter that associates the pedal operation with the reminder information according to the pedal operation detection result of the pedal operation detection unit 11 .

[0126] and Figure 1 Unlike the display mode switching unit 12 shown, when the detection result of the pedal operation by the pedal operation detection unit 11 changes, the display mode switching unit 13 displays an animation indicating the transition of the display mode when switching from the display mode before the detection result changes to the display mode after the detection result changes.

[0127] Hereinafter, the display mode switching process performed by the display mode switching unit 13 will be described in detail.

[0128] The display mode switching unit 13 compares the pedal operation detection results repeatedly output from the pedal operation detection unit 11 with each other, thereby determining whether the pedal operation detection result has changed.

[0129] If the detection result of the pedal operation changes, the display mode switching unit 13 determines the change mode of the detection result.

[0130] As the change mode of the detection result of the pedal operation, for example, the following modes (1) to (6) are conceivable.

[0131] (1) Change from "with" brake pedal operation to "without" brake pedal operation

[0132] (2) Change from "no" pedal operation to "with" brake pedal operation

[0133] (3) Change from "with" accelerator pedal operation to "without" accelerator pedal operation

[0134] (4) Change from "no" pedal operation to "with" accelerator pedal operation

[0135] (5) Change from "with" brake pedal operation to "with" accelerator pedal operation

[0136] (6) Change from “with” accelerator pedal operation to “with” brake pedal operation

[0137] “No” pedal operation means that neither the operation of the brake pedal nor the operation of the accelerator pedal is detected.

[0138] After determining the change mode of the detection result, when switching from the display mode before the detection result changes to the display mode after the detection result changes, the display mode switching unit 13 displays an animation indicating the transition of the display mode.

[0139] That is, if the change mode of the detection result is mode (1), the display mode switching unit 13 changes from Fig.13 The speedometer display shown in A switches to Fig.13 In the middle of the speedometer display mode shown in C, the display Fig.13 The display mode of the speedometer shown in B is changed, and an animation showing the transition of the display mode is displayed.

[0140] Fig.13 A is an explanatory diagram showing the display form of the speedometer when operation of the brake pedal is detected.

[0141] Fig.13 B is an explanatory diagram showing the state in which the display mode of the speedometer is being switched.

[0142] Fig.13C is an explanatory diagram showing the display mode of the speedometer when neither the operation of the brake pedal nor the operation of the accelerator pedal is detected.

[0143] exist Fig.13 In the display form of the speedometer shown in B, the dotted line graphic displayed in an arc shape around "50 km / h" is a fourth speed display graphic indicating that the vehicle speed is "50 km / h".

[0144] When the dot pattern is extended in the circumferential direction, it becomes a dotted line pattern, and when the dotted line pattern is extended in the circumferential direction, it becomes a curved line pattern. Therefore, the appearance of the fourth speed display pattern, which is a collection of a plurality of dotted line patterns, is between the appearance of the first speed display pattern, which is a collection of a plurality of dot patterns, and the appearance of the third speed display pattern, which is a curved line pattern. Therefore, the display mode switching unit 13 displays the first speed display pattern, the fourth speed display pattern, and the third speed display pattern in the order of the first speed display pattern, the fourth speed display pattern, and the third speed display pattern, respectively, so that the display mode looks like being drawn by animation.

[0145] If the detection result changes in the manner (4), for example, the display mode switching unit 13 changes from Fig.14 The speedometer display shown in A switches to Fig.14 In the middle of the speedometer display mode shown in C, the display Fig.14 The display mode of the speedometer shown in B is changed, and an animation showing the transition of the display mode is displayed.

[0146] Fig.14 A is an explanatory diagram showing a display mode of the speedometer when neither the operation of the brake pedal nor the operation of the accelerator pedal is detected.

[0147] Fig.14 B is an explanatory diagram showing the state in which the display mode of the speedometer is being switched.

[0148] Fig.14 C is an explanatory diagram showing the display mode of the speedometer when operation of the accelerator pedal is detected.

[0149] exist Fig.14 In the display form of the speedometer shown in B, a plurality of bar graphics displayed in an arc shape around "50 km / h" are fifth speed display graphics indicating that the vehicle speed is "50 km / h".

[0150] The line width of the plurality of bar-shaped graphics included in the fifth speed display graphics is thicker than the line width of the plurality of bar-shaped graphics included in the second speed display graphics. Therefore, the appearance of the fifth speed display graphics, which is a collection of bar-shaped graphics with thick line width, is between the appearance of the third speed display graphics, which is a curve graphic, and the appearance of the second speed display graphics, which is a collection of bar-shaped graphics with thin line width. Therefore, the display mode switching unit 13 displays the third speed display graphics, the fifth speed display graphics, and the second speed display graphics in the order of the third speed display graphics, the fifth speed display graphics, and the second speed display graphics, respectively, so that the display mode looks like being drawn by animation.

[0151] In the above second embodiment, the display control device 3 is configured so that when the detection result of the pedal operation by the pedal operation detection unit 11 changes, the display mode switching unit 13 displays an animation indicating the change of the display mode when the display mode before the detection result changes to the display mode after the detection result changes. Therefore, the display control device 3 can notify the driver of the vehicle whether the driver has performed a pedal operation without providing a dedicated display area on the instrument panel 4 of the vehicle, and can also notify the driver of the change of the pedal operation.

[0152] Furthermore, the present invention can freely combine the various embodiments, modify any constituent elements of the various embodiments, or omit any constituent elements in the various embodiments.
