(Example of items), etc. may be displayed as menu items 510, which will be described later.

Next, the configuration of the operation input device 30 will be described with reference to FIGS. 2A and 2B. 2A is a front view of the operation input device 30, and FIG. 2B is a diagram showing a cross-sectional structure taken along line bb in FIG. 2A. Here, the description will be made assuming that the operation input device 30 is used to select the menu item 510 (see FIG. 3) in the menu image 500 shown in FIG. 1.

The operation input device 30 is a touch sensor that detects the position where the user's thumb or the like touches the operation surface (operation position C), and as shown in FIG. 2B, it includes a front cover 31, a sensor sheet 32, a spacer 33, and the like. , is provided. The operation input device 30 allows the user to perform an operation of touching the operation surface with a thumb or the like (hereinafter referred to as a touch operation) or an operation of tracing a predetermined trajectory (hereinafter referred to as a gesture operation). detects the position where the thumb or the like touches the operation surface (operation position C), outputs a signal (position signal) indicating the operation position C, and when the user makes a selection (decision), the selection (decision) is detected. ) and outputs, for example, a signal (selection signal, in other words, selection (decision) detection signal) indicating that selection (decision) has been made.

The surface cover 31 of the operation input device 30 is formed into a sheet shape from a light-shielding insulating material such as synthetic resin, and has a three-dimensional shape with a convex cross section intermittently along the circumference of a circle centered on the center point Q. a convex portion (convex region) 34 (area with a radial pattern in FIG. 2A) formed in the convex portion (convex region) 34; a relatively flat flat portion (flat region) 35 connected to the convex portion (convex region) 34; has. The convex portion (convex region) 34 has a mountain-shaped cross section (convex cross section), and the mountain (convex shape) is long in the direction (inward) toward the center point Q and short in the opposite direction, outward. It has a contour line (ridge line). The convex portion (convex region) 34 is configured by providing the peaks (convex shape) intermittently along the circumference of a circle centered on the center point Q.

Further, as shown in FIG. 2B, a sensor sheet 32 is provided below the convex portion (convex region) 34 of the front cover 31, and the portion including the sensor sheet 32 allows the above-mentioned operation position detection section 36 to be detected. configured. For example, the user can detect the operation position detection unit 36 by recognizing the slope of the convex portion (convex region) 34 in the longitudinal direction (direction toward the center point Q, in other words, inward) with the touch of a finger. The approximate position of the finger on the screen can be recognized, and the operation input device 30 can be operated without looking at the operation input device 30. In other words, blind operation is possible. Note that there may be cases where the above-mentioned convex portion (convex region) 34 is not provided, but even in this case, the user can position the hand (finger) along the circumference of a circle centered on the center point Q. When the user moves the hand (finger), the user can perceive the trajectory of the hand (finger) that the user moved (the trace of the temporal change in the position where the finger etc. contacted the operating surface of the touch sensor). You can get an idea of the approximate position of the circle on the circumference of the circle. Therefore, even in this case, blind operation is possible.

The sensor sheet 32 is disposed along the circumference of a circle centered on the center point Q, at least on the back side of the front cover 31 corresponding to the convex portion (convex region) 34, and is arranged to guide the operating position C of the user's finger. It is detected and outputs information regarding the operation position C of the user's finger (information on the operation position or a signal indicating the operation position) to the control device 20 (vehicle display control device 21). The sensor sheet 32 is formed integrally with the front cover 31 by drawing, for example, so that it has the same shape as the front cover 31 (see FIG. 2B). By integrally molding the surface cover 31 and the sensor sheet 32 in this way, the surface cover 31 and the sensor sheet 32 become like a single sheet, and the stepped shape of the above-mentioned convex portion (convex area) 34 is a curved shape of the single sheet. It will be composed of parts (raised parts). Moreover, by integrally molding in this way, the back surface of the front cover 31 and the front surface of the sensor sheet 32 come into contact with each other. As a result, the detection portions of the sensor sheet 32 are arranged corresponding to the stepped shape of the front cover 31. As described above, since the detection parts of the sensor sheet 32 are arranged corresponding to the stepped shape of the front cover 31, the movement of the user's finger, etc. Even if the above is performed, for example, the vehicle display control device 21 can detect the position of the user's finger.

The spacer 33 is located on the back side of the sensor sheet 32, and is formed to match the shape of the front cover 31 and sensor sheet 32, which are integrally molded. , is a member that maintains the above shape.

A plurality of determination operation detection sections 37 (five in the example of FIG. 2B) are provided on the back side of the operation position detection section 36. The determining operation detecting section 37 is electrically connected to the control device 20 (including the vehicle display control device 21), and the user selects the operating surface of the operating position detecting section 36 (the convex portion (convex area) of the front cover 31). )) When an operation of pressing 34 (hereinafter referred to as a pressing operation) is performed, the decision operation detection section 37 is pressed, thereby detecting that the user has made a selection (decision). A signal (selection signal, in other words, selection (decision) detection signal) is output. The output selection (decision) detection signal is sent to the control device 20 (including the vehicle display control device 21). Based on the sent selection (decision) detection signal, the vehicle display control device 21 determines, for example, which menu item 510 has been selected among the plurality of menu items 510 included in the menu image 500, and selects the selected menu item 510. An operation menu image corresponding to the selection is generated and displayed on the display device 10. As a result, the display of the operation menu is switched according to the content of the selected menu item 510.

The return switch 38 is a switch located apart from the operation position detection section 36 and the decision operation detection section 37. When the user presses down the operation surface of the return switch 38 (in other words, a press operation is performed), a return signal is transmitted to the vehicle display control device 21 in the control device 20. Based on the return signal from the return switch 38, the vehicle display control device 21 returns the display of the menu image 500 to the most recent past operation menu image. In other words, switching to the immediately previous display is performed.

Next, details of the menu image 500 displayed on the display device 10 will be explained using FIG. 3. According to some embodiments, menu image 500 is a radial menu. A radial menu is a plurality of menu items 510 arranged continuously or intermittently on an open or closed figure. For example, a radial menu is a continuous partial circle (sector area) that is divided into two lines that extend radially from the center of the circle, and an arc between these two lines. The menu is arranged in the circumferential direction, with items assigned to each partial circle. In the following description, the control device 20 acquires or searches for information related to the control state of the electronic device 200, and allocates the acquired or searched information as an image to a partial circle (sector area) constituting the menu image 500. The icon image 510 will be referred to as a menu item 510, and the designated image 520 whose position changes according to the movement of the user's finger (hand) (detected by the operation input device 30) will be referred to as a pointer.

The menu item 510 is an image having a display area divided into sector areas, and as an initial display mode, for example, as shown in FIG. Ru. In the in-vehicle device operation system 100 of this embodiment, a hierarchy item 511, a device operation execution item 512, and a display item 513 are displayed as the menu item 510.

The hierarchy item 511 is a display area (partial circle or sector area) in which the type of electronic device 200 to be operated (for example, "AIR CONTROL") and information indicating the control state (for example, set temperature "28 degrees Celsius") are partitioned. By selecting this hierarchical item 511 by operating the operation input device 30, a new plurality of hierarchical items 511 specifying, for example, the air volume, wind direction, temperature setting, etc. of the air conditioner. It is possible to shift to a hierarchical display mode in which an image of a new menu image 500 including (new menu item 510) is displayed.

For example, when the hierarchy item 511 related to the air conditioning ECU 204 is specified by operating the operation input device 30, the display on the display device 10 shifts to the hierarchy display mode. Menu items 510 displayed in the hierarchical display mode include equipment operation execution items related to the air volume and wind direction of the air conditioner related to the air conditioning ECU 204 (hierarchical display mode). By selecting the device operation execution item 512 related to air volume and wind direction, the air volume and air direction of the air conditioner can be changed, and by selecting the hierarchical item 511 related to temperature setting, it is possible to shift to a hierarchical display mode related to temperature setting. can.

The device operation execution item 512 is an image displaying items (for example, “ABS”) and setting values for controlling the electronic device 200, and the device operation execution item 512 is selected by operating the operation input device 30. By doing so, it is possible to cause the electronic device 200 to execute various processes in accordance with the displayed items and setting values. Specifically, for example, by selecting "TCS" or the like using the operation input device 30, it is possible to cause the vehicle ECU 201 to execute on/off processing of the TCS function.

Note that the selected (determined) device operation execution item 512 is displayed in a display mode J2a in which the color and shape have changed to indicate that it has been selected, and the user is made aware that it has been selected (determined). good.

The display item 513 is, for example, an image in which vehicle information (eg, water temperature, oil temperature), etc. input from the vehicle ECU 201 is displayed in a divided display area, and is an image for transmitting information to the user. By selecting this display item 513 by operating the operation input device 30, detailed information on the displayed information can be displayed.

The information displayed in the divided display area (partial circle or sector area) of the display item 513 includes information related to various sensor information (for example, water temperature, oil temperature, etc.) output from the vehicle ECU 201, and information related to the own vehicle 1. Information related to various settings (for example, on/off of functions such as ABS, TCS, ECS, driving modes such as ECO mode and SPORT mode), navigation information output from the navigation ECU 202 (for example, arrival time, distance to target point, turn Information related to audio ECU 203 (playback time, song title, etc.), information indicating air conditioning ECU 204 settings (e.g., temperature setting, air volume, wind direction, etc.), electronic equipment 200 connected to information communication equipment 205 This is information acquired/searched from the electronic device 200 by the control device 20, such as information indicating the control state of the electronic device (for example, presence or absence of incoming call, content of mail). The display in the menu item 510 is updated with the information that the control device 20 continuously or intermittently acquires/retrieves from the electronic device 200.

Furthermore, the menu item 510 may be an image based not only on information acquired/searched by the control device 20 from the electronic device 200 but also based on information generated by the control device 20 itself. Specifically, for example, if the control device 20 has a timekeeping function, a stopwatch image may be displayed as the menu item 510. Further, when the display device 10 has a timekeeping function, the control device 20 may execute the timekeeping function of the display device 10 and cause the display device 10 to display a stopwatch image as the menu item 510.

Furthermore, the menu item 510 in FIG. 3 has a selectable width W. The selectable width W is the width of the position signal C that allows the menu item 510 to be specified by operating the operation input device 30. That is, the menu item 510 with a large selectable width W has a wide range of position signals C that can be specified, making it easier to specify. The selectable widths W of the plurality of menu items 510 may all be the same, but each menu item 510 may have a different selectable width W. In addition, the selectable width W may depend on the method of operation on the operation input device 30, the state of the own vehicle 1, the state of the electronic device 200, the state of the driver of the own vehicle 1 (or a passenger other than the driver), or any of these. It may be changed as appropriate depending on the combination.

The pointer 520 is an image extending from the center point P of the circle toward the menu item 510 side and indicating a guideline for specifying the menu item 510 (specified menu item 515) specified by the operation position C by the operation input device 30. According to the movement of the operation position C (see FIG. 2A) of the operation input device 30, the designated position D is smoothly changed and the specified menu item 515 is switched. By viewing this pointer 520, the user (driver, etc.) can confirm the menu item 510 (designated menu item 515) specified by the operation of the operation input device 30. Note that the pointer 520 can be used to display a cursor designation image 521 that highlights the outline of the designated menu item 515, a pointer designation image 522 that points from outside the designated menu item 515, a change in the color of the designated menu item 515, or a menu that is not designated. Even if it is replaced by changing the color of the item 510 (menu item other than the specified menu item 515), enlarging the specified menu item 515, shrinking the unspecified menu item 510 (menu item other than the specified menu item 515), etc. Often, it may be a combination of these.

Next, a more specific configuration of the control device 20 of this embodiment will be described with reference to FIG. 4. Here, the control device 20 refers to a configuration including a vehicle display control device 21 and an operation execution device 25. Note that in FIG. 4, parts common to those in FIG. 1 are denoted by the same reference numerals.

The vehicle display control device 21 includes one or more processors 22 , a memory 23 , and an image processing circuit 24 . FIG. 4 is only one example of an implementation, and the illustrated components may be combined into fewer components or there may be additional components. For example, image processing circuitry 24 (eg, a graphics processing unit) may be included in one or more processors 22. Furthermore, the processor 22 may have some or all of the functions of the operation execution device 25, which will be described later.

The I/O interface 210 also supports a personal area network (PAN) such as a Bluetooth (registered trademark) network, a local area network (LAN) such as an 802.11x Wi-Fi (registered trademark) network, 4G or LTE (registered trademark). ) may include a wireless communication interface that connects to a wide area network (WAN), such as a cellular network.

As illustrated, the processor 22 is interconnected with an I/O interface 210 so as to be able to exchange information with various electronic devices 200 connected to the vehicle display control device 21. The I/O interface 210 includes, for example, a vehicle ECU 201, a navigation ECU 202, an audio ECU 203, an air conditioning ECU 204, an information communication device 205, and a gear position sensor, a brake sensor, a speed sensor, an acceleration sensor (not shown) provided in the host vehicle 1, Sensors such as an accelerator sensor are connected so that they can exchange information. Display device 10 is operably coupled to processor 22 and image processing circuitry 24 . Accordingly, images displayed by display device 10 may be based on image data received from processor 22 and/or image processing circuitry 24. The processor 22 and the image processing circuit 24 control images displayed by the display device 10 based on information obtained from the I/O interface 210. Note that the I/O interface 210 may have a function of processing (converting, calculating, analyzing) information received from other electronic devices connected to the display device 10.

The processor 22 and the operation execution device 25 in the control device 20 perform a touch operation or draw a predetermined trajectory on the operation surface of the operation input device 30 by the user in order to specify one item included in the menu image 500. A position signal C generated in response to a tracing gesture operation and a selection (decision) signal generated in response to a pressing user operation are input from the operation input device 30.

The image processing circuit 24 in the vehicle display control device 21 generates an image of the menu image 500. For example, an image of a menu (operation menu) including a plurality of menu items 510 can be created by extracting (reading) a usable memory from a plurality of memories 23 prepared in advance and incorporating necessary information by image composition. generate. However, the present invention is not limited to this, and by arranging a plurality of items (combining images of items) according to an arrangement stored in advance in the memory 23 or an arrangement determined by a program stored in the memory 23. , an image of a menu (menu item) may be generated, or an image may be generated by rendering. The generated image is temporarily stored in an image RAM (not shown) or the like.

Note that the vehicle display control device 21 can generate an image using information from the electronic devices 200 (vehicle ECU 201, navigation ECU 202, audio ECU 203, air conditioning ECU 204, information communication device 205), or An image may be generated based only on image data stored in advance in the memory 23 without using the image data.

The rate of change or the acceleration of change may be estimated from C.

Next, in step S2, the vehicle display control device 21 acquires the state of the own vehicle 1.

The vehicle display control device 21 sets a predetermined range of display area α centered on the indicated position D corresponding to the position signal C, or based on the position signal C according to the moving direction of the position signal C. A display area L in a first direction and a display area R in a second direction opposite to the first direction are respectively set (step S3). For example, when the position signal C moves in the first direction, the display area L in the first direction based on the position signal C may be made larger than the display area R in the second direction. In addition to these, the display area α in a predetermined range (or the display area L in the first direction and the display area R in the second direction) is adjusted according to the state of the host vehicle 1 acquired in step S2.

It is displayed with a second visibility lower than the first visibility (step S4).

The vehicle display control device 21 determines whether the elapsed time outside the predetermined range of display area α has become longer than a predetermined time. In other words, it is determined whether the elapsed time since the object was removed from the object to be displayed with the first visibility has become longer than a predetermined time (step S5). If the elapsed time is not longer than the predetermined time (NO in step S5), the process ends and the process starts again from step S1.

If the elapsed time has become longer than the predetermined time (YES in step S5), the vehicle display control device 21 determines that the elapsed time since the object was removed from the object to be displayed with the first visibility has become longer than the predetermined time. The area is changed from a first visibility to a second visibility. Thereby, it is possible to prevent the visibility of the display area from suddenly decreasing. Note that the vehicle display control device 21 may gradually reduce the visibility when changing from the first visibility to the second visibility.
