DETAILED DESCRIPTION

[0026] 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.

[0027] Implementation Method 1

[0028] Figure 1 1 is a diagram showing the configuration of the display control device 2 according to the first embodiment.

[0029] Figure 2 1 is a hardware configuration diagram showing the hardware of the display control device 2 according to the first embodiment.

[0030] The shift lever 1 receives a shift operation of the vehicle and outputs shift selection information indicating the currently selected shift to the display control device 2 .

[0031] Figure 1 The illustrated display control device 2 has a shift operation detection section 11 , a display data storage section 12 , and a display control section 13 .

[0032] Figure 1 The display control device 2 shown includes a display data storage unit 12 . However, this is just an example, and the display data storage unit 12 may be provided outside the display control device 2 .

[0033] The display control device 2 causes an instrument panel (hereinafter referred to as “instrument panel”) 3 to display a speedometer, a tachometer, a fuel consumption meter, a fuel gauge, an energy-saving meter, a water temperature meter, a distance meter, or a vehicle status.

[0034] The instrument panel 3 is an instrument panel provided at the driver's seat of the vehicle, and displays a speedometer, a tachometer, a fuel consumption meter, a fuel gauge, an energy-saving meter, a water temperature meter, a distance meter, or a vehicle status.

[0035] The shift operation detection unit 11 is configured to detect the shift operation of the gear shifter 11 by, for example, Figure 2 The shift operation detection circuit 21 shown is implemented.

[0036] The shift operation detection unit 11 acquires shift selection information from the shift lever 1 .

[0037] The shift operation detection unit 11 detects a shift operation of the vehicle by monitoring changes in the shift selection information.

[0038] When detecting a shift operation of the vehicle, the shift operation detection unit 11 specifies the content of the shift position switching of the vehicle accompanying the operation of the shift lever based on the change in the shift selection information.

[0039] The shift operation detection unit 11 outputs shift switching information indicating the content of the shift position switching of the vehicle to the display control unit 13 .

[0040] The display data storage unit 12 is, for example, Figure 2 The display data storage circuit 22 is shown implemented.

[0041] The display data storage unit 12 stores display data of images showing the transition of the vehicle state when the vehicle shift position is switched, for each shift position switching pattern.

[0042] The display data stored in the display data storage unit 12 includes animation data for animating a graphic representing a vehicle state transition.

[0043] The display control unit 13 performs, for example, Figure 2 The display control circuit 23 shown is implemented.

[0044] The display control unit 13 acquires, from the display data storage unit 12 , display data related to the switching content indicated by the shift switching information output from the shift operation detection unit 11 .

[0045] The display control unit 13 causes the instrument panel 3 of the vehicle to display an image based on the acquired display data.

[0046] When the display control unit 13 displays an image on the instrument panel 3 of the vehicle based on the display data, the display control unit 13 displays a graphic in an animated manner based on the animation data included in the display data.

[0047] exist Figure 1In the embodiment, it is assumed that the shift operation detection unit 11, the display data storage unit 12, and the display control unit 13, which are components of the display control device 2, are respectively Figure 2 That is, it is assumed that the display control device 2 is implemented by the shift operation detection circuit 21, the display data storage circuit 22 and the display control circuit 23.

[0048] Here, the display data storage circuit 22 is, for example, a non-volatile or volatile semiconductor memory such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EPROM (Erasable Programmable ReadOnly Memory), EEPROM (Electrically Erasable Programmable Read Only Memory), a magnetic disk, a floppy disk, an optical disk, a compact disk, a mini disk, or a DVD (Digital Versatile Disc).

[0049] The shift operation detection circuit 21 and the display control circuit 23 are, 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 combination thereof.

[0050] The components of the display control device 2 are not limited to those implemented by dedicated hardware, and the display control device 2 may be implemented by software, firmware, or a combination of software and firmware.

[0051] Software or firmware is stored as a program in a computer's memory. Computer means hardware that executes the 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).

[0052] Figure 3 This is a hardware configuration diagram of a computer when the display control device 2 is realized by software, firmware, or the like.

[0053] When the display control device 2 is implemented by software or firmware, the display data storage unit 12 is configured on the computer's memory 31. A program for causing the computer to execute the processing of the shift operation detection unit 11 and the display control unit 13 is stored in the memory 31. Then, the processor 32 of the computer executes the program stored in the memory 31.

[0054] In addition, Figure 2 In FIG. 1 , an example is shown in which the components of the display control device 2 are respectively implemented by dedicated hardware. Figure 3 , an example is shown in which the display control device 2 is implemented by software or firmware. However, this is just an example, and some components of the display control device 2 may be implemented by dedicated hardware, and the remaining components may be implemented by software or firmware.

[0055] Next, Figure 1 The operation of the display control device 2 shown will be described.

[0057] The shift lever 1 receives a shift operation of the vehicle and outputs shift selection information indicating the currently selected shift to the shift operation detection unit 11 of the display control device 2 .

[0058] The shift operation detection unit 11 acquires shift selection information from the shift lever 1 .

[0059] The shift operation detection unit 11 detects the shift operation of the vehicle by monitoring the change of the shift selection information. Figure 4 Step ST1).

[0060] When the shift operation detection unit 11 detects the shift operation of the vehicle, it determines the gear position switching content of the vehicle accompanying the operation of the shift lever according to the change of the shift selection information. Figure 4 Step ST2).

[0061] The shift operation detection unit 11 outputs shift switching information indicating the content of the shift position switching of the vehicle to the display control unit 13 .

[0062] If the shift operation is, for example, a switching operation from the parking gear P to the reverse gear R, the shift operation detection unit 11 outputs shift switching information indicating that the gear position is switched from the parking gear P to the reverse gear R to the display control unit 13 .

[0063] If the shift operation is, for example, a shift operation from the neutral position N to the drive position D, the shift operation detection unit 11 outputs shift switching information indicating that the shift position is switched from the neutral position N to the drive position D to the display control unit 13 .

[0064] The display data storage unit 12 stores display data of images showing the transition of the vehicle state when the vehicle shift position is switched, for each shift position switching pattern.

[0066] These display data include, for example, animation data of graphics representing the state of the vehicle.

[0067] The image showing the vehicle state transition accompanying the switching from the parking gear P to the reverse gear R shows that the vehicle state transitions from the parking state to the state in which the vehicle can move backward.

[0068] The image showing the vehicle state transition accompanying the switching from the neutral gear N to the drive gear D shows that the vehicle state transitions from a state where the engine power is not transmitted to the axle to a state where the vehicle can move forward.

[0069] The image showing the vehicle state transition accompanying the switching from the reverse gear R to the neutral gear N shows that the vehicle state transitions from the state in which the vehicle can move backward to the state in which the power of the engine is not transmitted to the axle.

[0070] The display control unit 13 acquires the shift switching information from the shift operation detection unit 11 .

[0071] The display control unit 13 obtains display data ( Figure 4 Step ST3).
