The left end of the windshield glass 17 is fixed to a front pillar on the left side of the vehicle (not shown).

[0014] Here, the instrument panel 14 is provided with an image display area V1. Display area V1 is a meter display located on the right side of the vehicle on instrument panel 14, and predetermined information is displayed by first image display device 40 (see FIG. 2). First image display device 40 is connected to various meter devices mounted on vehicle 12, and is located in a position within the driver's field of vision when the driver is looking ahead of the vehicle.

[0015] An image display area V2 is provided on the windshield glass 17. The display area V2 is set above the vehicle with respect to the display area V1, and is configured as a projection surface onto which an image is projected by a second image display device 42 (see FIG. 2). Here, the second image display device 42 is a head-up display device provided on the vehicle front side of the instrument panel 14, and is configured so that an image is projected from the second image display device 42, which is a head-up display device, onto the display area V2 of the windshield glass 17. In other words, the display area V2 is a part of the windshield glass 17 that serves as the projection surface for the head-up display device.

[0016] The steering wheel 16 has a substantially annular rim portion 16A, and a hub portion 16B forming the center portion is provided on the inner periphery of the rim portion 16A. The right side of the rim portion 16A is connected to the hub portion 16B by spokes 16C, and the left side of the rim portion 16A is connected to the hub portion 16B by spokes 16C. A first right operation switch 34R, a second right operation switch 36R, and a right function selector switch 38R are provided on the right spoke portion 16C. A first left operation switch 34L, a second left operation switch 36L, and a left function selector switch 38L are provided on the left spoke portion 16C.

[0017] The right first operation switch 34R is formed in a substantially rectangular shape and is located in the upper right portion of the right spoke 16C. The right first operation switch 34R is configured to allow input in four directions (up, down, left, and right), and each direction is assigned a function.

[0018] In this embodiment, as an example, the right first operation switch 34R is equipped with an electrostatic sensor (not shown), and when the occupant simply touches the right first operation switch 34R, the touched function is selected. Furthermore, when the occupant presses the right first operation switch 34R with the function selected, the selected function is executed. Similar electrostatic sensors are also equipped in the right second operation switch 36R, the right function selector switch 38R, the left first operation switch 34L, the left second operation switch 36L, and the left function selector switch 38L.

[0019] The right second operation switch 36R is formed in a generally elongated rectangular shape with the vertical direction as the longitudinal direction, and is located to the left of the right first operation switch 34R. The right second operation switch 36R is configured to allow input in two directions, up and down, and each direction is assigned a different function.

[0020] The right function selector switch 38R is formed in a generally elongated rectangular shape with the left-right direction as the longitudinal direction, and is disposed below the first right operation switch 34R and the second right operation switch 36R. The right function selector switch 38R is a switch for switching functions. Specifically, by operating the right function selector switch 38R, the functions assigned to the first right operation switch 34R and the second right operation switch 36R are switched. In this embodiment, as an example, two functions are assigned to each operation switch, and the functions are switched each time the right function selector switch 38R is operated.

[0021] The left first operation switch 34L is formed in a generally rectangular shape that is bilaterally symmetrical to the right first operation switch 34R, and is located in the upper left part of the left spoke portion 16C. The left first operation switch 34L is configured to allow input in four directions, up, down, left, and right, and each has its own function. A skill is assigned.

[0022] The left second operation switch 36L is formed in a generally elongated rectangular shape that is bilaterally symmetrical to the right second operation switch 36R, and is located to the right of the left first operation switch 34L. The left second operation switch 36L is configured to allow input in two directions, up and down, and each direction is assigned a different function.

[0023] The left function selector switch 38L is formed in a generally elongated rectangular shape that is bilaterally symmetrical to the right function selector switch 38R, and is disposed below the first left operation switch 34L and the second left operation switch 36L. The left function selector switch 38L is also a switch for switching functions. Specifically, by operating the left function selector switch 38L, the functions assigned to the first left operation switch 34L and the second left operation switch 36L are switched.

[0024] Here, a vehicle 12 is provided with a vehicle display control device 10. The vehicle display control device 10 of this embodiment is, for example, a display ECU (Electronic Control Unit) that performs various controls.

[0025] (Hardware configuration of the vehicle display system S) As shown in FIG. 2, the vehicular display system S includes a vehicular display control device 10.

[0026] The vehicle display control device 10 includes a CPU (Central Processing Unit: processor) 20, It is configured to include a ROM (Read Only Memory) 22, a RAM (Random Access Memory) 24, a storage 26, a communication interface (communication I / F) 28, and an input / output interface (input / output I / F) 30. Each component is connected to each other via an internal bus 32 so that they can communicate with each other.

[0027] The CPU 20 is a central processing unit that executes various programs and controls each component. That is, the CPU 20 reads programs from the ROM 22 or storage 26 and executes the programs using the RAM 24 as a work area. The CPU 20 also controls the above components and performs various arithmetic operations in accordance with the programs stored in the ROM 22 or storage 26.

[0028] 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 by an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and is a non-temporary recording medium that stores various programs including an operating system and various data. In this embodiment, the ROM 22 or the storage 26 stores programs for performing display processing, etc.

[0029] The communication I / F 28 is an interface for the vehicle display control device 10 to communicate with an external server and other devices, and may be, for example, a CAN (Controller Area Network), an Ethernet, or the like. Standards used include LTE (registered trademark), LTE (Long Term Evolution), FDDI (Fiber Distributed Data Interface), and Wi-Fi (registered trademark).

[0030] The input / output interface 30 is electrically connected to the right first operation switch 34R, the right second operation switch 36R, the right function changeover switch 38R, the left first operation switch 34L, the left second operation switch 36L, the left function changeover switch 38L, the first image display device 40, and the second image display device 42.

[0031] The first image display device 40 is a device that displays a predetermined image in a display area V1 of the meter display, and the second image display device 42 is a device that displays a predetermined image in a display area V2 of the head-up display.

[0032] The vehicle display control device 10 is also electrically connected to a driving assistance ECU 44. The driving assistance ECU 44 of this embodiment controls, for example, ACC (active cruise control) and LTA (lane tracing assist). For this reason, the driving assistance ECU 44 is configured to be able to acquire signals from sensors that detect the periphery of the vehicle 12.

[0033] (Functional configuration of the vehicle display control device 10) The vehicular display control device 10 uses the above hardware resources to realize various functions. The functional configuration realized by the vehicular display control device 10 will be described with reference to FIG.

[0034] 3, the vehicular display control device 10 is configured to include, as functional components, a right operation detection unit 50, a left operation detection unit 52, a vehicle state acquisition unit 54, an operation unit image display unit 56, and a state image display unit 58. Each functional component is realized by the CPU 20 reading and executing a program stored in the ROM 22 or the storage 26.

[0035] The right operation detection unit 50 detects that the right operation unit has been operated. Specifically, the right operation detection unit 50 detects that any of the right first operation switch 34R, the right second operation switch 36R, and the right function selector switch 38R has been operated. The operation here includes not only the act of the occupant pressing a switch but also the act of the occupant touching a switch. For this reason, the right operation detection unit 50 detects, for example, that the occupant has touched the right first operation switch 34R through a signal from an electrostatic sensor. The right operation detection unit 50 also detects, for example, that the occupant has pressed the right first operation switch 34R through a signal from a pressure sensor.

[0036] The left operation detection unit 52 detects that a left operation unit has been operated. Specifically, the left operation detection unit 52 detects that any of the first left operation switch 34L, the second left operation switch 36L, and the left function selector switch 38L has been operated. To this end, the left operation detection unit 52 detects, for example, that the occupant has touched the first left operation switch 34L through a signal from an electrostatic sensor. Furthermore, the left operation detection unit 52 detects, for example, that the occupant has pressed down the first left operation switch 34L through a signal from a pressure sensor.

[0037] The vehicle state acquisition unit 54 acquires the vehicle state based on signals detected by various sensors. For example, the vehicle state acquisition unit 54 acquires the state of on-board equipment installed in the vehicle 12. The on-board equipment here refers to an air conditioner, an audio system, etc. The vehicle state acquisition unit 54 also acquires the state of the driving assistance functions of the vehicle 12.

[0038] When the operation unit image display unit 56 detects an operation of the right operation unit, it displays a right operation unit image corresponding to the right operation unit in the right portion of the display area V2. When the operation unit image display unit 56 detects an operation of the left operation unit, it displays a left operation unit image corresponding to the left operation unit in the left portion of the display area V2. Furthermore, the operation unit image display unit 56 highlights the part corresponding to the switch being touched by the occupant. Furthermore, when the operation unit image display unit 56 detects that the right function selector switch 38R or the left function selector switch 38L has been operated, it displays an animation in which the operation unit image is reversed.

[0039] The status image display unit 58 displays the current status of the function assigned to the operated switch in the display area V2. Furthermore, the status image display unit 58 changes the status image in response to a change in status due to the operation of the operation unit. The function of 58 will be explained with reference to FIGS.

[0040] 4 shows a state in which the occupant is not touching any of the operation switches. In this state, a central image 60M indicating the vehicle status is always displayed in the central portion of the display area V2. In this embodiment, the current speed of the vehicle 12 is displayed as the central image 60M. In addition, a substantially arc-shaped indicator is displayed above the speed.

[0041] When the occupant touches any of the first left operation switch 34L, the second left operation switch 36L, and the left function selector switch 38L from the state shown in Fig. 4, the state transitions to the state shown in Fig. 5. As shown in Fig. 5, a left operation unit image 64M is displayed at the left end of the display area V2 by the function of the operation unit image display unit 56. Here, the operation unit image display unit 56 moves the central image 60M to the right from the position shown in Fig. 4, and displays the left operation unit image 64M to the left of the central image 60M.

[0042] The left operation unit image 64M includes a first left operation switch image 34LM shaped like the first left operation switch 34L, a second left operation switch image 36LM shaped like the second left operation switch 36L, and a left function selector switch image 38LM shaped like the left function selector switch 38L. Fig. 5 also shows a state in which the occupant is touching the right end of the first left operation switch 34L.

[0043] An icon for decreasing the air conditioner's airflow is displayed on the left side of the left first operation switch image 34LM, and selecting this icon decreases the airflow by a predetermined amount. An icon for increasing the air conditioner's airflow is displayed on the right side of the left first operation switch image 34LM, and selecting this icon increases the airflow by a predetermined amount. Here, in the state of FIG. 5, because the occupant is touching the right side of the left first operation switch 34L, the icon on the right side of the left first operation switch image 34LM is displayed in inverse video and highlighted by an oval.

[0044] An icon for increasing the air conditioner's set temperature is displayed at the top of the left first operation switch image 34LM, and selecting this icon increases the set temperature by a predetermined amount. An icon for decreasing the air conditioner's set temperature is displayed at the bottom of the left first operation switch image 34LM, and selecting this icon decreases the set temperature by a predetermined amount.

[0045] A volume up icon is displayed at the top of the left second operation switch image 36LM, and selecting this icon increases the volume of music and other sounds played in the vehicle cabin by a predetermined amount. Also, a volume down icon is displayed at the bottom of the left second operation switch image 36LM, and selecting this icon decreases the volume by a predetermined amount.

[0046] The left function changeover switch image 38LM displays a function changeover icon, and when this icon is selected, the function assigned to the first left operation switch 34L is changed.

[0047] To the right of the left operation unit image 64M, a right status image 70M is displayed by the function of the status image display unit 58. At the top of the right status image 70M, text is displayed indicating that this is the screen for setting the air conditioner's airflow. Also, below the text, an icon resembling a fan is displayed.

[0048] At the bottom of the right state image 70M, a roughly bar-shaped icon extending to the left and right is displayed, and it has a tapered shape that narrows as it moves from the right to the left. Furthermore, only the left half of the bar-shaped icon is colored, so the current air conditioner airflow level can be intuitively determined. The bar icon has a minus sign on the left side and a plus sign on the right side.

[0049] When the occupant presses the right part of the first left operation switch 34L in the state shown in Figure 5, the air conditioner airflow is increased. At this time, the right state image 70M changes as shown in Figure 6 due to the function of the state image display unit 58.

[0050] As shown in Fig. 6, the bar-shaped icon in the right-hand state image 70M has a larger colored area than in Fig. 5. Specifically, the bar-shaped icon is colored from halfway to the right, making it possible to visually confirm that the air conditioner's airflow has increased. Note that in Fig. 6, for the sake of convenience, the increased airflow portion is represented in a different color, but this is not limited thereto, and the entire icon may be displayed in the same color.

[0051] Next, when the occupant touches any of the first right operation switch 34R, the second right operation switch 36R, and the right function selector switch 38R from the state shown in Fig. 4, the state transitions to the state shown in Fig. 7. As shown in Fig. 7, a right operation unit image 62M is displayed at the right end of the display area V2 by the function of the operation unit image display unit 56. Here, the operation unit image display unit 56 moves the central image 60M to the right from the position shown in Fig. 4, and displays a left operation unit image 64M to the right of the central image 60M.

[0052] The right operation unit image 62M includes a right first operation switch image 34RM shaped like the right first operation switch 34R, a right second operation switch image 36RM shaped like the right second operation switch 36R, and a right function selector switch image 38RM shaped like the right function selector switch 38R. Fig. 7 also shows a state in which the occupant is touching the right function selector switch 38R.

[0053] Here, as an example, no icon is displayed at the top or right of the right first operation switch image 34RM. In this way, when there is no assigned function, no icon is displayed.

[0054] An icon related to setting the distance between vehicles is displayed on the left side of the right first operation switch image 34RM, and selecting this icon allows the user to set the distance between vehicles. That is, the function of setting the distance between vehicles is assigned to the left side of the right first operation switch 34R.

[0055] An icon related to switching of the driving mode is displayed below the right first operation switch image 34RM, and selecting this icon switches the driving mode. That is, a driving mode switching function is assigned to the lower part of the right first operation switch 34R.

[0056] An icon for switching the radar cruise mode ON and OFF is displayed at the top of the right second operation switch image 36RM, and selecting this icon switches the radar cruise mode ON and OFF. Also, an icon for switching the LTA ON and OFF is displayed at the bottom of the right second operation switch image 36RM, and selecting this icon switches the LTA ON and OFF. In this way, information related to driving assistance is displayed on the right operation unit image 62M.

[0057] The right function changeover switch image 38RM displays a function changeover icon, and when this icon is selected, the function assigned to the right first operation switch 34R is changed.

[0058] A left status image 72M is displayed on the left side of the right operation unit image 62M by the function of the status image display unit 58. The left status image 72M indicates that a page switching button is selected. The character indicating this is displayed.

[0059] When the occupant presses the right function changeover switch 38R in the state of FIG. 7, the operation unit image display unit 56 displays an animation in which the right first operation switch image 34RM of the right operation unit image 62M is inverted.

[0060] Fig. 8 shows a state in the middle of the flipping animation. As shown in Fig. 8, the right second operation switch image 36RM and the right function selector switch image 38RM do not change, and only the right first operation switch 34RM is flipped.

[0061] 9, when the inversion of the right first operation switch 34RM is completed, the function assigned to the right first operation switch 34RM is changed. In other words, the icons displayed above, below, left, and right of the right first operation switch 34RM are changed.

[0062] (action) Next, the operation of this embodiment will be described.

[0063] (Display processing) An example of the display processing by the vehicular display control device 10 will be described with reference to the flowchart shown in Fig. 10. This display processing is executed by the CPU 20 reading a display program from the ROM 22 or the storage 26, expanding it in the RAM 24, and executing it.

[0064] In step S102, the CPU 20 acquires the operation status of the operation unit. Specifically, the CPU 20 acquires information from electrostatic sensors (not shown) mounted on each of the first right operation switch 34R, second right operation switch 36R, right function selector switch 38R, first left operation switch 34L, second left operation switch 36L, and left function selector switch 38L.

[0065] In step S104, the CPU 20 determines whether the occupant's hand is in contact with the right operation unit. Specifically, if the CPU 20 detects, through the function of the right operation detection unit 50, that the occupant's hand is in contact with any one of the right first operation switch 34R, the right second operation switch 36R, and the right function selector switch 38R, the result of step S104 is affirmative and the process proceeds to step S106. On the other hand, if the CPU 20 does not detect, through the function of the right operation detection unit 50, that the occupant's hand is in contact with any one of the right first operation switch 34R, the right second operation switch 36R, and the right function selector switch 38R, the result of step S104 is negative and the process proceeds to step S110. The process from step S110 onwards will be described later.

[0066] In step S106, the CPU 20 moves the center image 60M to the left using the function of the operation unit image display unit 56. In step S108, the CPU 20 displays the right operation unit image 62M and the left state image 72M in the display region V2 (see FIG. 7).

[0067] On the other hand, if the occupant's hand is not touching the right operation unit, the CPU 20 determines in step S110 whether the occupant's hand is touching the left operation unit. Specifically, if the CPU 20 detects through the function of the left operation detection unit 52 that the occupant's hand is touching any one of the first left operation switch 34L, the second left operation switch 36L, and the left function selector switch 38L, the result of step S110 is affirmative and the CPU 20 proceeds to processing in step S112. On the other hand, if the CPU 20 does not detect through the function of the left operation detection unit 52 that the occupant's hand is touching any one of the first left operation switch 34L, the second left operation switch 36L, and the left function selector switch 38L, the result of step S110 is negative and the display processing ends.

[0068] In step S112, the CPU 20 moves the center image 60M to the right using the function of the operation unit image display unit 56. In step S114, the CPU 20 displays the left operation unit image 64M and the right state image 70M in the display region V2 (see FIG. 5).

[0069] As described above, in the vehicular display control device 10 according to this embodiment, when an operation unit provided on the steering wheel 16 is operated, an operation unit image corresponding to the operation unit is displayed in the display area V2 set in front of the driver's seat. Also, a status image indicating the current status of the function assigned to the operated switch is displayed in the display area V2. This allows the occupant to grasp the current status of the function without looking at another display or the like.

[0070] In particular, in this embodiment, since the display area V2 is set on the windshield glass 17, the occupant can view the operation unit image and the status image while directing his or her line of sight toward the windshield glass 17.

[0071] In this embodiment, the occupant can grasp that the state has changed simply by looking at the status image. Furthermore, the occupant can recognize which switch they are touching simply by looking at the highlighted portion. This eliminates the need for the occupant to lower their eyes and directly check the switch.

[0072] Furthermore, in this embodiment, the occupant can grasp the status of the in-vehicle devices simply by looking at the right-state image 70M displayed in the display area V2, while the occupant can grasp the status of the driving assistance functions simply by looking at the left-state image 72M displayed in the display area V2.

[0073] 7 to 9, when the function of the right first operation switch image 34RM is switched, the right first operation switch image 34RM displayed in the display region V2 appears to be inverted when viewed from the occupant, allowing the occupant to intuitively recognize that the function assigned to the right first operation switch image 34RM has been changed. Also, the occupant can intuitively recognize that by operating the right function selector switch 38R again, the right first operation switch image 34RM will be further inverted and return to its original state.

[0074] Although the vehicular display system S and the vehicular display control device 10 according to the embodiment have been described above, it goes without saying that they can be embodied in various forms without departing from the spirit of the present invention.
