Summary of Invention

Problems to be Solved by the Invention

[0005] In the apparatus of Patent Document 1, when operating the air conditioning equipment, the image displayed on the display is switched to an image including only icons related to the air conditioning equipment, so that the image representing the magnitude of the control parameter such as air volume can be displayed on the display in a relatively large size. Therefore, according to this apparatus, the user can perform the desired operation on the image even while being subjected to vibrations from the vehicle, which is considered to improve operability. However, this configuration has a problem that convenience is poor because other information such as a map is not displayed on the display during operation of the air conditioning equipment.

[0006] This invention has been made in view of the circumstances described above, and aims to provide a vehicle display device that can display a large amount of information and has good operability. [Means for solving the problem]

[0007] To solve the above problems, the present invention provides a display device installed in a vehicle, comprising: a display unit capable of receiving touch operations by a user; a display control unit that displays a bar icon in a predetermined bar icon display area of ​​the display unit, the bar icon including a bar for representing the magnitude of a predetermined control parameter of an in-vehicle device and a pointer that moves along the bar; a device control unit that sets the magnitude of the control parameter based on the position of the pointer relative to the bar; and a notification unit that performs notification control to notify the user that a touch operation has been received when a touch operation is performed in a predetermined operation reception area of ​​the display unit, wherein, after the notification control is performed, if a swipe operation is performed to slide the operation position of the touch operation, the display control unit performs pointer movement control to move the pointer in accordance with the change in the operation position, regardless of whether the operation position of the swipe operation is within the bar icon display area or not (Claim 1).

[0008] In this invention, the pointer can be moved even if the swipe operation position is outside the bar icon display area, eliminating the need for the user to perform pointer movement operations within the limited area of ​​the bar icon display area. Therefore, the area of ​​the bar icon display area can be kept small to secure space for displaying other information, thereby improving convenience while also improving operability when moving the pointer. Moreover, in this invention, notification control is performed before pointer movement control. Therefore, the user can be made aware that the pointer can be moved by performing a swipe operation after the notification. Consequently, it is possible to encourage highly operable operations and reliably provide the user with a good operating experience.

[0009] In the above configuration, preferably, the display control unit performs notification control to inform the user that a touch operation has been performed by displaying the bar and the pointer in the bar icon display area when a touch operation is performed in the operation reception area (Claim 2).

[0010] This configuration allows users to intuitively understand that they can move the pointer by swiping.

[0011] In the above configuration, preferably, the display control unit displays a main icon representing the type of control parameter in the operation reception area, and the bar icon display area is set to an area that does not overlap with the operation reception area (Claim 3).

[0012] With this configuration, icons representing the control parameters are displayed even while notification control and pointer movement control are being performed, allowing the user to recognize the type of control parameter they are operating.

[0013] In the above configuration, preferably, the display control unit performs the pointer movement control when the condition is met that the touch operation within the operation reception area and the swipe operation after the notification control are consecutive (Claim 4).

[0014] With this configuration, the user can move the pointer with a simple swipe operation, using a position within the operation reception area as the starting point.

[0015] In the above configuration, preferably, the display control unit performs the pointer movement control when the following conditions are met: the touch operation within the operation reception area and the swipe operation after the implementation of the notification control are not consecutive, and a swipe operation is performed after the implementation of the notification control with respect to the position within the bar icon display area (Claim 5).

[0016] In this configuration, even if a touch operation within the input area is interrupted, pointer movement control is performed if a swipe operation is then performed using the position within the bar icon display area as the starting point. Therefore, the user does not need to restart the operation from the touch operation within the input area in order to perform pointer movement control, improving convenience.

[0017] In the above configuration, preferably, when the pointer movement control is performed, the display control unit determines the amount of pointer movement based only on the amount of change in the operation position of the swipe operation for a predetermined effective operation direction (Claim 6).

[0018] This configuration prevents changes in the operating position in a direction different from the user's intended direction of operation, caused by vehicle vibrations or other factors, from affecting pointer movement. Therefore, the pointer can be moved more reliably in accordance with the user's intentions.

[0019] In the above configuration, preferably, the bar has a shape that extends along the effective operating direction, and the display control unit moves the pointer along the effective operating direction (Claim 7).

[0020] In this configuration, the direction of change of the operation position that determines the amount of pointer movement coincides with the direction of pointer movement. Therefore, users can intuitively perform operations to move the pointer.

[0021] In the above configuration, preferably, the bar has a shape that extends in a predetermined direction, and when the pointer movement control is performed, the display control unit disables the swipe operation to move the pointer to the one side when the pointer has reached one end of the bar in the longitudinal direction (Claim 8).

[0022] This configuration allows the pointer to be displayed in a position that is more appropriately aligned with the bar.

[0023] In the above configuration, preferably, the in-vehicle device is an air conditioning device, and the control parameter is at least one of a flow rate and a temperature of air supplied by the air conditioning device into a vehicle cabin (Claim 9).

[0024] According to this configuration, it is possible to secure an area for displaying information other than the air volume or temperature of the air conditioning device on the display unit, while improving the operability of the air volume operation or temperature operation of the air conditioning device.

[0025] In the above configuration, preferably, the in-vehicle device is an audio device, and the control parameter is a volume of sound generated by the audio device (Claim 10).

[0026] According to this configuration, it is possible to secure an area for displaying information other than the volume of the audio device on the display unit, while improving the operability of the volume operation of the audio device. [Effects of the Invention]

[0027] As described above, according to the present invention, it is possible to provide a vehicular display device capable of displaying a large amount of information and achieving excellent operability. [Brief Description of the Drawings]

[Modes for carrying out the invention]

[0029] A preferred embodiment of the present invention will be described below with reference to the drawings.

[0030] (Overall structure) Figure 1 is a schematic diagram showing the area around the driver's seat of a vehicle V equipped with a vehicle display device 1 according to an embodiment of the present invention. Figure 2 is a block diagram showing the control system of the vehicle display device 1. Hereafter, the front-rear direction of the vehicle V will be simply referred to as the front-rear direction, and the left-right direction of the vehicle V, i.e., the left-right direction when the vehicle V is facing forward, will be simply referred to as the left-right direction. The directions shown in each figure are the directions defined above.

[0031] The vehicle display device 1 includes a display 10 and a control unit 100 that controls the display 10 and in-vehicle equipment. The display 10 corresponds to the "display unit" of the present invention.

[0032] The display 10 displays various information and accepts user operations. The display 10 displays various information while emitting light. In this embodiment, the display 10 is made of an organic EL panel. However, the light emission method of the display 10 is not limited to the organic EL method, and the display 10 may be made of a liquid crystal panel, a plasma panel, or the like. The display 10 is a so-called touch panel and accepts touch operations from the user. In this embodiment, the display 10 is made of a pressure-sensitive touch panel. However, the input method of the display 10 is not limited to the pressure-sensitive method, and the display 10 may be made of a capacitive panel or the like.

[0033] The touch operations accepted by the display 10 are those in which a finger, pen, or the like is placed on the display 10 to specify a point (position) on the screen 20 of the display 10. If the display 10 uses a capacitive panel or the like and is a non-contact touch panel, then bringing a finger, pen, or the like close to the display 10 is also included in the above-mentioned touch operations. In the following explanation, we will assume that a finger is used to perform the touch operation, as this is representative of the tools used for such operations.

[0034] In this embodiment, the above-mentioned touch operations include at least tap operations, double-tap operations, long-tap operations, and swipe operations, and the control unit 100 accepts each of these operations as a different operation. The control unit 100 identifies which of the above operations the input touch operation is based on the contact time and contact interval between the finger and the display 10. A tap operation is an operation in which the finger is briefly in contact with the screen 20 of the display 10. A double-tap operation is an operation in which the tap operation is repeated twice in a short period of time. A long-tap operation is a so-called long-press operation, in which the finger is in contact with the same point on the screen 20 for a longer time than a tap operation. A swipe operation is an operation in which the position of the touch operation is moved by sliding the finger, and the finger is moved while in contact with the screen 20.

[0035] The display 10 is positioned so that it can be operated by the driver seated in the driver's seat. In this embodiment, it is positioned so that the driver can operate the display 10 with one hand while gripping the steering wheel 52 with the other hand. Specifically, the display 10 is located approximately in the center in the vehicle width direction of the instrument panel 51, which is located at the front of the passenger compartment R.

[0036] The control unit 100 includes a microprocessor consisting of a well-known CPU, ROM, RAM, etc. Functionally, the control unit 100 has a display control unit 102, an equipment control unit 104, and a navigation calculation unit 106.

[0037] The control unit 100 (display control unit 102) controls the display content and display format of the display 10 based on operations performed on the display 10.

[0038] The control unit 100 (device control unit 104) controls the in-vehicle equipment based on operations performed on the display 10. In this embodiment, the air conditioning equipment 60 and the audio equipment 70 mounted on the vehicle V are electrically connected to the control unit 100 as in-vehicle equipment controlled by the control unit 100.

[0039] The air conditioning equipment 60 includes a heat exchanger and the like, and heats or cools the air through heat exchange in the heat exchanger, and supplies the air into the passenger compartment R. The vehicle V is provided with a plurality of air outlets 65 on the instrument panel 51, etc., and the air conditioning equipment 60 supplies air into the passenger compartment R through these air outlets 65. In this embodiment, the vehicle V has a driver's seat and a passenger seat, and the air outlets 65 include a driver's side air outlet 65A provided on the driver's side and mainly supplying air to the driver's seat, and a passenger side air outlet 65B provided on the passenger's side and mainly supplying air to the passenger seat. Some of the air outlets 65 are provided on the instrument panel 51.

[0040] The air conditioning unit 60 can change the airflow rate and temperature of the air supplied to the vehicle compartment R. The air conditioning unit 60 can individually change the temperature of the air flowing into the vehicle compartment R via the driver's side outlet 65A and the temperature of the air flowing into the vehicle compartment R via the passenger side outlet 65B. On the other hand, the air conditioning unit 60 can change the airflow rate output to each outlet 65A and 65B collectively. The user can adjust the airflow rate flowing into the vehicle compartment R through the outlets 65A and 65B by changing the opening degree of the shutters provided at each outlet 65A and 65B. Hereinafter, the temperature of the air supplied to the vehicle compartment R by the air conditioning unit 60 will be referred to as the conditioned temperature, the temperature of the air passing through the driver's side outlet 65A will be referred to as the first conditioned temperature, and the temperature of the air passing through the passenger side outlet 65B will be referred to as the second conditioned temperature. Furthermore, in the following, the airflow rate supplied into the vehicle compartment R by the air conditioning equipment 60 will be referred to as the air conditioning airflow rate.

[0041] The control unit 100 (equipment control unit 104) can control the air conditioning temperature and air conditioning airflow, and transmits control signals to the air conditioning equipment 60 to change these.

[0042] The audio equipment 70 includes a head unit, amplifier, speakers, etc. The audio equipment 70 amplifies the sound signal generated by the head unit in conjunction with the playback of a sound source, etc., using the amplifier and outputs it from the speakers. The speakers are incorporated into the inner wall of the vehicle interior R so as to output sound towards the vehicle interior R. The sound pressure, i.e., volume, of the sound output from the speakers of the audio equipment 70 can be changed. Hereinafter, the volume of the speakers of the audio equipment 70 will be referred to as the speaker volume.

[0043] The control unit 100 (device control unit 104) can control the type of sound source and speaker volume played by the audio device 70, and transmits control signals to the audio device 70 to change these.

[0044] In this embodiment, the vehicle display device 1 constitutes a navigation system. The control unit 100 (navigation calculation unit 106) performs various calculations related to navigation. For example, the control unit 100 (navigation calculation unit 106) determines the current position of the vehicle V and calculates the route to the destination set by operations on the display 10. The display 10 displays the determined current position of the vehicle V, the route to the destination, etc., together with a map or the like. In other words, in this embodiment, the navigation system mounted on the vehicle V is further enhanced with functions to operate the air conditioning equipment 60 and the sound equipment 70.

[0045] In this embodiment, the control unit 100 is configured to enable wireless LAN communication and wireless communication with surrounding base stations.

[0046] (Image on display) Next, we will describe the images displayed on the screen 20 of the display 10. Where appropriate, the screen 20 of the display 10 will simply be referred to as the display screen 20. Figure 3 shows an example of an image displayed on the display screen 20. Hereafter, the display screen 20 is divided into three main display areas. Specifically, the display screen 20 is divided into a first display area 20A, which constitutes the upper end of the display screen 20; a third display area 20C, which constitutes the lower end of the display screen 20; and a second display area 20B, which lies between these two areas.

[0047] The first display area 20A displays information such as the time, temperature, and communication status between the control unit 100 and the outside, which is basically information that cannot be operated by the user. The second display area 20B is the area that occupies most of the display screen 20 and displays the map, the type of sound source being played, etc. The third display area 20C displays multiple function icons F1 to F8. These function icons F1 to F8 each function as controls for operating the display 10, air conditioning equipment 60, and audio equipment 70, etc. In this embodiment, these function icons F1 to F8 are always displayed in the third display area 20C of the display screen 20. In this embodiment, the area in which each of the function icons F1 to F8 is shown, and which includes these icons and is approximately the same size as one index finger of an average-sized adult American male (AM50) in the left-right direction, functions as a control that accepts touch operations, etc. Furthermore, if a single function icon contains multiple icons (designs), for each icon, an area encompassing that icon and extending horizontally to the left and right, roughly the same size as one index finger of an average-sized American adult male (AM50), functions as a touch input area.

[0048] The function icons include the first air conditioning temperature icon F1, the second air conditioning temperature icon F2, the air conditioning airflow icon F3, and the volume icon F4. These icons F1 to F4 each function as controls to operate the in-vehicle equipment and change the magnitude of its control parameter, and represent the type of control parameter they correspond to. Specifically, the first air conditioning temperature icon F1 represents the first air conditioning temperature and functions as a control to change the first air conditioning temperature by operating the air conditioning equipment 60. The second air conditioning temperature icon F2 represents the second air conditioning temperature and functions as a control to change the second air conditioning temperature by operating the air conditioning equipment 60. The air conditioning airflow icon F3 represents the air conditioning airflow and functions as a control to change the air conditioning airflow by operating the air conditioning equipment 60. The volume icon F4 represents the speaker volume and functions as a control to change the speaker volume by operating the audio equipment 70. These first air conditioning temperature icon F1, second air conditioning temperature icon F2, air conditioning air volume icon F3, and volume icon F4 correspond to the "main icons" of the present invention.

[0049] The two air conditioning temperature icons F1 and F2 each include a set temperature display icon F1A and F2A that shows the current set values ​​for the first and second air conditioning temperatures, a temperature increase icon F1B and F2B located to the right of the set temperature display icon F1A and F2A that functions as an operator for increasing the air conditioning temperature, and a temperature decrease icon F1C and F2C located to the left of the set temperature display icon F1A and F2A that functions as an operator for decreasing the air conditioning temperature.

[0050] The function icons include a home icon F5 for displaying a pre-set home image in the second display area 20B, a navigation icon F6 for displaying maps and other information in the second display area 20B and enabling input of destinations, etc., and an audio icon F7 for displaying the type of sound source being played in the second display area 20B and enabling operation of the audio equipment 70 (excluding speaker volume). The function icons also include two setting icons F8 for configuring various settings of the display 10, etc.

[0051] (Control unit control details) Next, we will describe the control performed by the control unit 100 when the first air conditioning temperature icon F1, the second air conditioning temperature icon F2, the air conditioning air volume icon F3, and the volume icon F4, which are features of the present invention.

[0052] First, the control when the second air conditioning icon F2 is operated, representing the four icons F1 to F4 mentioned above, will be explained using the flowcharts in Figures 4 to 6 and Figures 7 and 8. Figures 7 and 8 are enlarged views of a portion of the display screen 20. In Figure 7 and other figures, the symbol D represents a user's (human) hand to indicate the user's operation, but it is shown smaller than the actual size of a human hand to minimize overlap with other figures.

[0053] The control unit 100 determines whether or not a touch operation has occurred in the operation reception area A201 for the second air conditioning temperature control within the third display area 20C (step S1). As shown in Figure 7, in this embodiment, the operation reception area A201 for the second air conditioning temperature control is approximately rectangular in shape. The operation reception area A201 for the second air conditioning temperature control is set near the area where the second air conditioning temperature control icon F2 is displayed.

[0054] In this embodiment, the operation reception area A201 for the second air conditioning control is set to extend to the left and right of the area where the second air conditioning icon F2 functions as an operator (the area where touch operations, etc., are received as operations performed on the second air conditioning icon F2), by approximately 0.5 index fingers of an average-sized adult American male (AM50). Specifically, the second air conditioning icon F2 includes three icons, i.e., three patterns: a set temperature display icon F2A, a temperature increase icon F2B, and a temperature decrease icon F2C. The area where the second air conditioning icon F2 functions as an operator is approximately three index fingers of the adult male. In contrast, the operation reception area A201 for the second air conditioning control is set to extend from a position 0.5 index fingers to the right of the area where the second air conditioning icon F2 functions as an operator to a position 0.5 index fingers to the left of the area where it functions as an operator. In the example diagram, the operation reception area A201 for the second air conditioning control is located in the horizontal direction, from a position midway between the right edge of the second air conditioning icon F2 and the left edge of the air conditioning air volume icon F3, to a position slightly to the left of the left edge of the second air conditioning icon F2. In the vertical direction, the operation reception area A201 for the second air conditioning control is located in the vertical direction, from a position near the lower edge of the third display area 20C, below the lower edge of the second air conditioning icon F2, to a position midway between the upper edge of the second air conditioning icon F2 and the lower edge of the second display area 20B.

[0055] Returning to Figure 4, if the determination in step S1 is NO and no touch operation has been performed on the operation reception area A201 for the second air conditioning temperature control, the control unit 100 repeats step S1. That is, steps S2 and beyond are performed only when a touch operation has been performed on the operation reception area A201 for the second air conditioning temperature control.

[0056] If the determination in step S1 is YES and a touch operation is performed in the operation reception area A201 for the second air conditioning temperature control, the control unit 100 determines whether the duration of the touch operation performed in the operation reception area A201 for the second air conditioning temperature control is equal to or greater than a predetermined determination time (step S2). If this determination is NO and the duration of the touch operation performed in the operation reception area A201 for the second air conditioning temperature control is less than the determination time, the control unit 100 proceeds to step S201. The above determination time is set in advance and stored in the control unit 100. Note that this determination time is set to be approximately the same as the operation time of the tap operation.

[0057] In step S201, the control unit 100 determines whether a tap operation has been performed on the temperature-increasing icon F2B or the temperature-decreasing icon F2C of the second air conditioning temperature icon F2. If the determination in step S201 is YES, the control unit 100 changes the second air conditioning temperature according to the operation on these icons F2B and F2C (step S202). Specifically, if a tap operation is performed on the temperature-increasing icon F2B, the control unit 100 issues a command to the air conditioning equipment 60 to raise the second air conditioning temperature by a unit temperature. If a tap operation is performed on the temperature-decreasing icon F2C, the control unit 100 issues a command to the air conditioning equipment 60 to lower the second air conditioning temperature by a unit temperature. The unit temperature is pre-set and stored in the control unit 100. After step S202, or if the determination in step S201 is NO, the control unit 100 terminates the process (returns to step S1).

[0058] On the other hand, if the determination in step S2 is YES and the duration of the touch operation performed on the operation reception area A201 for the second air conditioning temperature control is equal to or greater than the determination time, the control unit 100 displays the bar icon F20 for the second air conditioning temperature control in the bar icon display area A202 for the second air conditioning temperature control (step S3). The display of this bar icon F20 allows the user to recognize that the above-mentioned touch operation (a touch operation that lasted for longer than the determination time) has been received by the control unit 100. This control that displays the bar icon F20 corresponds to the "notification control" of the present invention. Furthermore, the control unit 100 (display control unit 102) that implements this control functions as the "notification unit" of the present invention.

[0059] The bar icon F20 for the second air conditioning temperature includes a bar F21 representing the magnitude of the second air conditioning temperature and a pointer F22 that moves along the bar F21. In this embodiment, the bar F21 is rod-shaped and extends in the left-right direction. The pointer F22 is approximately circular in shape, with a diameter about the same as the vertical dimension of the bar F21 and sufficiently smaller than the left-right dimension of the bar F21. The pointer F22 is displayed on the bar F21 and is displayed to move along the bar F21 in the left-right direction. Here, as described above, in this embodiment, the longitudinal direction of the bar F21 coincides with the left-right direction, and as will be described later, the amount of movement of the pointer F22 is determined based on the amount of change of the pointer F22 in the left-right direction, and the left-right direction corresponds to the "effective operating direction" of the present invention.

[0060] The bar icon display area A202 for the second air conditioning temperature control is set in the third display area 20C. In this embodiment, as shown in Figure 8, the bar icon display area A202 for the second air conditioning temperature control is substantially rectangular in shape. The bar icon display area A202 for the second air conditioning temperature control is set above the operation reception area A201 for the second air conditioning temperature control, in an area that does not overlap with it. In the example in Figure 8, in the vertical direction, the bar icon display area A202 for the second air conditioning temperature control is adjacent to the operation reception area A201 for the second air conditioning temperature control. The dimensions and area of ​​the bar icon display area A202 for the second air conditioning temperature control are larger in the horizontal direction than the dimensions and area of ​​the operation reception area A201 for the second air conditioning temperature control.

[0061] In this embodiment, the bar icon F20 is displayed such that, in the left-right direction, the starting position of the touch operation that triggered the display of the second air conditioning bar icon F20, i.e., the starting position TP of the contact between the user's finger and the display 10, coincides with the center position of the bar F21 in the left-right direction. In the up-down direction, the bar icon F20 is displayed near the center of the second air conditioning bar icon display area A202. In the left-right direction, the bar icon F20 is displayed at a position spaced inward from both edges of the second air conditioning bar icon display area A202.

[0062] Returning to the flowchart in Figure 4, after step S3, the control unit 100 determines whether the following conditions are met: that the touch operation is continuing and that a swipe operation has been performed with a point (position) within the operation reception area A201 for the second air conditioning temperature control. (Step S4) That is, this condition means that a swipe operation has been performed with a point within the operation reception area A201 for the second air conditioning temperature control, following the touch operation to display the bar icon F20. This condition is met if the user keeps their finger in contact with the operation reception area A201 for the second air conditioning temperature control before and after the bar icon F20 is displayed, and after the bar icon F20 is displayed, they perform a swipe operation without lifting their finger from the operation reception area A201. If the determination in step S4 is NO and the above condition is not met, the control unit 100 proceeds to step S7 in Figure 5.

[0063] On the other hand, if the determination in step S4 is YES and the above conditions are met, the control unit 100 performs bar slide control (step S5). Bar slide control is performed continuously until the touch operation is finished (until the determination in step S6 is YES), that is, until the user lifts their finger from the display 10. Bar slide control will be described later. If the user lifts their finger from the display 10 and the touch operation is finished (until the determination in step S6 is YES) YESIf this occurs, the bar slide control is terminated and the control unit 100 proceeds to step S7.

[0064] In step S7, the control unit 100 determines whether or not a touch operation has occurred in the bar icon display area A202 for the second air conditioning temperature control. That is, the control unit 100 determines whether a touch operation that had been completed has been performed again and whether the operation location is within the bar icon display area A202. If the determination in step S7 is NO and there is no touch operation in the bar icon display area A202 for the second air conditioning temperature control, the control unit 100 proceeds to step S14.

[0065] On the other hand, if the determination in step S7 is YES and a touch operation is performed on the bar icon display area A202 for the second air conditioning temperature control, the control unit 100 determines whether the touch operation performed is a swipe operation based on a position within the bar icon display area A202 (step S8). That is, it is determined whether the user touched the bar icon display area A202 with their finger and then slid their finger without lifting it from the display 10. If this determination is YES, the control unit 100 continues to perform bar slide control until the touch operation is completed (until the determination in step S10 is YES), that is, until the user lifts their finger from the display 10, as in steps S5 and S6 (step S9). . Yu When the user lifts their finger from display 10 and the touch operation ends (the judgment in step S10 is YES When this happens, the control unit 100 proceeds to step S14.

[0066] Returning to step S8, if the determination in step S8 is NO and the touch operation performed was not a swipe operation, the control unit 100 determines whether or not a tap operation was performed on bar F21 (step S11). If the determination in step S11 is NO, the control unit 100 proceeds to step S14. On the other hand, if the determination in step S11 is YES, the control unit 100 changes the display position of pointer F22 to the position where the tap operation was performed (step S12). The control unit 100 also changes the second air conditioning temperature according to the position of pointer F22 on bar F21 (step S13). Specifically, the control unit 100 calculates a set value by multiplying the distance between the position of pointer F22 and the left end position XL of bar F21 (Figure 8) by a predetermined value and adding this value to the lowest temperature corresponding to the left end position XL of bar F21, and issues a command to the air conditioning equipment 60 so that the second air conditioning temperature is set to this set value. After step S13, the control unit 100 proceeds to step S14.

[0067] Step S In step 14, the control unit 100 determines whether the termination condition is met, which is that no touch operation is performed on the bar icon display area A202 for the second air conditioning temperature for a predetermined period of time or longer, or that a touch operation is performed on an area other than the bar icon display area A202 for the second air conditioning temperature. The termination period is set in advance and stored in the control unit 100. If the determination in step S14 is NO and the termination condition is not met, the control unit 100 returns to step S7. On the other hand, if the determination in step S14 is YES and the termination condition is met, the control unit 100 cancels the display of the bar icon F20 (step S15). As a result, the control of changing the second air conditioning temperature in response to the operation on the second air conditioning temperature icon F2 is terminated.

[0068] Next, the details of the bar slide control performed in steps S5 and S9 will be explained using the flowchart in Figure 6.

[0069] When bar slide control is initiated, the control unit 100 first calculates the amount of change in the left-right direction of the operating position, i.e., the contact position between the user's finger and the display 10 (step S52). Next, the control unit 100 calculates a temporary pointer position, which is a temporary position of pointer F22, based on the direction of movement of the operating position in the left-right direction, the amount of change in the operating position calculated in step S52, and the position of pointer F22 at the start of the swipe operation (step S53). Specifically, if the operating position moves to the right by a predetermined amount, the temporary pointer position is calculated to be a position shifted to the right by the predetermined amount from the position of pointer F22 at the start of the swipe operation. On the other hand, if the operating position moves to the left by a predetermined amount, the temporary pointer position is calculated to be a position shifted to the left by the predetermined amount from the position of pointer F22 at the start of the swipe operation.

[0070] Next, the control unit 100 determines whether the temporary pointer position is to the right of the right end position XR (Figure 8) of bar F21 (step S54). If this determination is YES and the temporary pointer position is to the right of the right end position XR of bar F21, the control unit 100 sets the pointer position to the right end of bar F21 (step S55). On the other hand, if the determination in step S54 is NO, the control unit 100 then determines whether the temporary pointer position is to the left of the left end position XL (Figure 8) of bar F21 (step S56). If this determination is YES and the temporary pointer position is to the left of the left end position XL of bar F21, the control unit 100 sets the pointer position to the left end of bar F21 (step S57). On the other hand, if the determination in step S56 is NO and the temporary pointer position in the left-right direction is between the right end position XR and the left end position XL of bar F21, the control unit 100 sets the pointer position to the temporary pointer position (step S58). In this way, the control unit 100 limits the pointer position in the left-right direction to the area between the left end XL and the right end XR of bar F21.

[0071] Step S55, Step S 57 Or Step S58 After that, the control unit 100 moves the pointer F22 (display of pointer F22) to the set temporary pointer position (step S59). The control unit 100 also changes the second air conditioning temperature according to the position of pointer F22 on bar F21 (step S60). The specific procedure for changing the second air conditioning temperature according to the position of pointer F22 on bar F21 is the same as in step S13. After step S60, the process proceeds to step S6 or step S10.

[0072] Of the above bar slide control, the control including steps S52 to S59 corresponds to the "pointer movement control" of the present invention.

[0073] As described above, if a touch operation is performed on the operation reception area A201 for the second air conditioning temperature control for a period of time longer than the judgment time, the bar icon F20 for the second air conditioning temperature control will be displayed in the third display area 20C of the display screen 20. Then, if a swipe operation is performed after the display of the bar icon F20 for the second air conditioning temperature control, following the above touch operation, bar slide control will be started, and the position of the pointer F22 will change on the bar F21 as the operation position moves left or right, and the second air conditioning temperature will be changed according to the position of the pointer F22. Furthermore, in the left or right direction, the position of the pointer F22 is limited to the area between the left and right ends of the bar F21. That is, in the left or right direction, if the pointer F22 reaches one end of the bar F21, even if the operation position of the swipe operation changes to the other side, the operation will be invalid with respect to the movement of the pointer F22. Furthermore, when the bar icon F20 is displayed on the display 10, even if the user lifts their finger from the display 10, if a swipe operation is performed with the point within the bar icon display area A202 as the starting point, the bar slide control described above is initiated, and the position of the pointer F22 and the second air conditioning temperature are changed in accordance with the movement of the operation position.

[0074] At this point, once the bar slide control is initiated, the touch operation will cease (the determination in step S6 or S10 will be made). YESThe bar slide control will continue until (this happens). From this point on, even if the operation position moves out of the operation reception area A201 and the bar icon display area A202 for the second air conditioning temperature control during the swipe operation, the bar slide control will continue. Note that at the start of the bar slide control, the position of the touch operation is within the operation reception area A201 or the bar icon display area A202 for the second air conditioning temperature control.

[0075] Figure 9 shows an example of the display screen 20 when bar slide control is started and a swipe operation is performed. As shown in Figure 9, for example, even if the touch operation position TP moves from the first position TP1 in the operation reception area A201 for the second air conditioning temperature along the dashed line L1 to the second position TP2 outside the area A201 and the bar icon display area A202, the bar slide control continues until the touch operation is stopped, and the position of the pointer F22 and the second air conditioning temperature are changed based on the amount of change in the operation position of the touch operation.

[0076] Furthermore, in bar slide control, the position of the pointer F22 is changed by the amount of left-right movement of the touch operation position TP. Therefore, as in the example in Figure 9, even if the touch operation position TP changes significantly in the vertical direction, the position of the pointer F22 is changed by the left-right separation distance LT between the first position TP1 and the second position TP2, regardless of the vertical change of the touch operation position. Specifically, in the example in Figure 9, as a swipe operation is performed to the right, the position of the pointer F22 moves from position P1, which was the position before the start of bar slide control, to position P2, which is separated to the right by the above separation distance LT.

[0077] Figure 10 shows another example of the display screen 20 when bar slide control is initiated. In Figure 10, a swipe operation is performed along the dashed line L2, and the touch operation position TP moves to the right of the right end position XR of bar F21. As described above, in bar slide control, if the touch operation position TP moves to the right of the right end position XR of bar F21, the position of pointer F22 is set to the right end of bar F21, and if the touch operation position TP moves to the left of the left end position XL of bar F21, the position of pointer F22 is set to the left end of bar F21. Thus, in the example of Figure 10, pointer F22 is at the right end position of bar F21. P2 We will be moving to [location].

[0078] Furthermore, the control performed by the control unit 100 when the first air conditioning icon F1 is operated is the same as the explanation above for the control performed when the second air conditioning icon F2 is operated, but with "second air conditioning" replaced by "first air conditioning". The operation reception area for the first air conditioning, which is displayed in response to the operation of the first air conditioning icon F1, is set near the display area of ​​the first air conditioning icon F1, and the bar icon display area for the first air conditioning is set above the operation reception area for the first air conditioning.

[0079] (Control when operating the air conditioning fan speed icon) Next, we will explain the control performed by the control unit 100 when the air conditioning air volume icon F3 is operated. The control performed when the air conditioning air volume icon F3 is operated is generally the same as when the second air conditioning temperature icon F2 is operated, and will be briefly explained below.

[0080] Figures 11(a) and 11(b) correspond to Figures 7 and 8, respectively. Similar to the second air conditioning temperature icon F2, if a touch operation is performed for a duration longer than the judgment time on the operation reception area A301 for air conditioning air volume, which is set near the display area of ​​the air conditioning air volume icon F3, the control unit 100 displays an air conditioning air volume bar icon F30 in the air conditioning air volume bar icon display area A302, which includes a bar F31 and a pointer F32 that moves along the bar F31.

[0081] In this embodiment, similar to the operation reception area A201 for the second air conditioning temperature control, the operation reception area A301 for air conditioning air volume is set to be wider on both the left and right sides than the area where the air conditioning air volume icon F3 functions as an operator (the area where touch operations, etc., are received as operations performed on the air conditioning air volume icon F3). These wider areas are approximately the width of 0.5 index fingers of an average-sized American adult male (AM50). Specifically, the air conditioning air volume icon F3 includes two icons (designs): one consisting of a picture of a fan and another consisting of a number representing the air conditioning air volume level. The area where the air conditioning air volume icon F3 functions as an operator is the width of two index fingers of the adult male. In contrast, the operation reception area A301 for air conditioning air volume is set to be the area from 0.5 index finger widths to the right of the area where the air conditioning air volume icon F3 functions as an operator to 0.5 index finger widths to the left of this area. In the example diagram, the distance is measured from the midpoint between the left end of the air conditioning airflow icon F3 and the right end of the second air conditioning temperature icon F2, to the right end of the air conditioning airflow icon F3 and the home icon F5. left edge It is set to the area up to the midpoint. In the vertical direction, the operation reception area A201 for the second air conditioning temperature control and the operation reception area A301 for the air conditioning air volume control are set to the same position.

[0082] Similar to the bar icon display area A202 for the second air conditioning temperature, the bar icon display area A302 for the air conditioning airflow is set in the third display area 20C. Also, similar to the relationship between the operation reception area A201 and the bar icon display area A202 for the second air conditioning temperature icon F2, the bar icon display area A302 for the air conditioning airflow is set above the operation reception area A301 for the air conditioning airflow icon F3, in an area that does not overlap with it. Furthermore, the shape and dimensions of the bar icon F30 for the air conditioning airflow icon F3 are the same as the bar icon F20 for the second air conditioning temperature.

[0083] On the other hand, when operating the air conditioning air volume icon F3, unlike when operating the second air conditioning temperature icon F2, the volume increase icon F 34 The bar icon F30 is displayed to the right of the weight loss icon F33 The number F35 and the toggle icon F36 appear to the left of the bar icon F30. 34 This icon functions as a control for increasing the air conditioning airflow per unit volume. (Decrease icon F) 33 This icon functions as an operator to reduce the air conditioning airflow by one unit of airflow. The number F35 corresponds to the set value of the air conditioning airflow. The toggle icon F36 functions as an operator to switch between letting the air conditioning air into the vehicle cabin R and stopping it.

[0084] Furthermore, the control performed by the control unit 100 when the air conditioning airflow icon F3 is operated is, except for the processing when the determination in step S2 above is NO and the timing of the execution of step S201, in the flowcharts in Figures 4 to 6 and the above explanation using them, replace "operation reception area for second air conditioning temperature", "bar icon display area for second air conditioning temperature", and "bar icon for second air conditioning temperature" with "operation reception area for air conditioning airflow", "bar icon display area for air conditioning airflow", and "bar icon for air conditioning airflow", respectively, and replace "bar" and "pointer" with the respective terms. Air conditioning airflow The bar icon for the air conditioning is read as "bar" and "pointer," and the "heating icon," "cooling icon," and "unit temperature" are read as "increase icon," "decrease icon," and "unit airflow," respectively. When the air conditioning airflow icon F3 is operated, step S201 is performed if the judgment in step S11 is NO, not step S2, and if the judgment in step S2 is NO, the process proceeds to step S7 instead of step S201. Also, when the air conditioning airflow icon F3 is operated, if the judgment in step S201 is NO, a judgment is made as to whether or not the switching icon F36 has been operated. If this judgment is YES, the inflow and stop of air conditioning air into the vehicle compartment R are switched, and if this judgment is NO, the process proceeds to step S7. Also, in step S15, which is performed when the air conditioning airflow icon F3 is operated, the increase icon F is performed along with the bar icon F30. 34 Weight loss icon F 33 The display of the number F35, which represents the air conditioning airflow level, and the switch icon F36 will be canceled.

[0085] When the above control is implemented, if a touch operation is performed on the operation reception area A301 for air conditioning volume for a duration longer than the judgment time, similar to when the second air conditioning temperature icon F2 is operated, a bar icon F30 is displayed on the display 10. Then, if a swipe operation is performed from a point within the operation reception area A301 for air conditioning volume following the above touch operation, bar slide control is started, and the position of the pointer F32 changes on the bar F31 as the operation position moves left or right, and the air conditioning volume is changed according to the position of the pointer F32. Furthermore, even if the user lifts their finger from the display 10 while the bar icon F30 is displayed on the display 10, bar slide control is started if a swipe operation is performed from the bar icon display area A302 for air conditioning volume. Furthermore, even if the swipe operation position moves outside the air conditioning airflow control reception area A301 and the bar icon display area A302 after the start of bar slide control, the bar slide control continues, and the position of the pointer F32 and the air conditioning airflow are changed according to the amount the operation position moves.

[0086] (Control when operating the volume icon) Next, we will describe the control performed by the control unit 100 when the volume icon F4 is operated. The control performed when the volume icon F4 is operated is generally the same as that performed when the second air conditioning temperature icon F2 is operated, and will be briefly explained below.

[0087] Figures 12(a) and 12(b) correspond to Figures 7 and 8, respectively. Similar to the second air conditioning icon F2, if a touch operation is performed for a duration longer than the judgment time on the speaker volume operation reception area A401, which is set near the display area of ​​the volume icon F4, the control unit 100 displays a bar F41 and a pointer F that moves along the bar F41 on the speaker volume bar icon display area A402. 42 Displays the F40 bar icon for speaker volume, including the following.

[0088] In this embodiment, similar to the operation reception area A201 for the second air conditioning temperature control, the speaker volume operation reception area A401 is set to be wider on both the left and right sides than the area where the volume icon F4 functions as an operator (the area where touch operations, etc., are received as operations performed on the volume icon F4), by approximately 0.5 index fingers of an average-sized adult American male (AM50). Specifically, the volume icon F4 consists of one icon (design), and the area where the volume icon F4 functions as an operator is the width of one index finger of the adult male. In contrast, the speaker volume operation reception area A401 is set to be the area from 0.5 index fingers to the right of the area where the volume icon F4 functions as an operator to 0.5 index fingers to the left of the area where the volume icon F4 functions as an operator. In the example diagram, the control input area A401 for speaker volume is located midway between the left end of volume icon F4 and the right end of setting icon F8, and between the right end of volume icon F4 and the first air conditioning temperature icon F1. left edge It is set to the area up to the midpoint. In the vertical direction, there is the operation reception area A201 for the second air conditioning temperature control and the operation reception area A for the speaker volume. 401 It is set to the same position.

[0089] Similar to the bar icon display area A202 for the second air conditioning temperature control, the bar icon display area A402 for speaker volume is set in the third display area 20C. Also, similar to the relationship between the operation reception area A201 and the bar icon display area A202 for the second air conditioning temperature control icon F2, the bar icon display area A402 for speaker volume is set above the operation reception area A401 for speaker volume, in an area that does not overlap with it. 40 Its shape and dimensions are the same as the bar icon F20 for the second air conditioning temperature control.

[0090] On the other hand, when operating the volume icon F4, unlike when operating the second air conditioning temperature icon F2, the volume increase icon F 44 The bar icon F40 is displayed to the right of the weight loss icon F 43The numbers F45 and the toggle icon F46 are bar icons F 40 It will be displayed on the left side. Increase icon F 44 This icon functions as an operator for increasing speaker volume in increments of a unit level. (Decrease icon F) 43 The F46 icon functions as an operator to decrease the speaker volume in increments of a unit level. The number F45 corresponds to the speaker volume setting value. The F46 toggle icon functions as an operator to switch between outputting and stopping sound from the speaker.

[0091] Furthermore, when the volume icon F4 is operated, the control performed by the control unit 100 is as follows, except for the processing when the judgment in step S2 is NO and the timing of the execution of step S201, in the flowcharts in Figures 4 to 6 and the explanation above using these, the "operation reception area for second air conditioning temperature," the "bar icon display area for second air conditioning temperature," and the "bar icon for second air conditioning temperature" are read as the "operation reception area for speaker volume," the "bar icon display area for speaker volume," and the "bar icon for speaker volume," respectively; the "bar" and "pointer" are read as the "bar" and "pointer" of the bar icon for speaker volume, respectively; and the "temperature increase icon," "temperature decrease icon," and "unit temperature" are read as the "increase icon," "decrease icon," and "unit level," respectively. Note that when the volume icon F4 is operated, step S201 is performed when the judgment in step S11 is NO, not step S2, and if the judgment in step S2 is NO, the process proceeds to step S7 instead of step S201. Furthermore, when the volume icon F4 is operated, if the determination in step S201 is NO, it is determined whether or not the switch icon F46 has been operated. If this determination is YES, the output of sound from the speaker is switched on and off. If this determination is NO, the process proceeds to step S7. Also, in step S15, which is advanced when the volume icon F4 is operated, the increase icon F46 is activated along with the bar icon F40. 44 Weight loss icon F 43 The display of the number F45, which represents the speaker volume level, and the toggle icon F46 are canceled.

[0092] When the above control is implemented, the control acceptance area A for speaker volume will be activated, similar to the second air conditioning icon F2. 401 If a touch operation is performed on the device for longer than the judgment time, a bar icon F40 will be displayed on the display 10. Then, following the above touch operation, the speaker volume control input area A will be activated. 401 When a swipe operation is performed with the point within the bar as the starting point, bar slide control is initiated, and as the operation position moves left or right, the position of pointer F42 changes on bar F41, and the volume is changed according to the position of pointer F42. Furthermore, even if the user lifts their finger from the display 10 while the bar icon F40 is displayed on the display 10, bar slide control is initiated when a swipe operation is performed with the point within the bar icon display area A402 for speaker volume as the starting point. In addition, even if the operation position of the swipe operation moves out of the operation reception area A401 and the bar icon display area A402 for speaker volume after bar slide control has started, bar slide control continues, and the position of pointer F42 and the speaker volume are changed according to the amount of movement of the operation position.

[0093] (effect, etc.) As described above, in the vehicle display device 1 according to the above embodiment, even if the touch operation position moves out of the operation reception area A201 (A301, A401) and the bar icon display area A202 (A302, A402) after the start of bar slide control, the bar slide control continues, and the position of the pointer F22 (F32, F42) and the values ​​of the control parameters (air conditioning temperature, air conditioning airflow, speaker volume) are changed based on the amount of lateral movement of the operation position. For example, even if the user's touch operation position moves out of the operation reception area A201 (A301, A401) or the bar icon display area A202 (A302, A402) against the user's intention due to vibration of the vehicle V, the control parameters are changed.

[0094] Therefore, users do not need to perform operations within the limited range of the operation reception area A201 (A301, A401) or the bar icon display area A202 (A302, A402) in order to change the values ​​of control parameters, resulting in improved operability. In other words, there is no need to enlarge these areas A201 (A301, A401) and A202 (A302, A402) in order to improve operability. Accordingly, with the above-described vehicle display device 1, the operation reception area A201 (A301, A401) or the bar icon display area A202 (A302, A402) can be kept small to secure display area for other information such as maps, thereby improving convenience through the display of such information while improving the operability of changing control parameters.

[0095] Furthermore, in the vehicle display device 1 according to the above embodiment, bar icons F20 (F30, F40) are displayed before the start of bar slide control. Therefore, when bar slide control is started, the pointer F22 (F32, F42) is moved to bar F21 (F 31 ,F 41 This allows users to recognize that they can move along the specified area. Therefore, it is possible to encourage users to operate in a wider area than the above-mentioned areas A201 (A301, A401) and A202 (A302, A402), and to reliably provide a good user experience. In addition, it is possible to make users aware that operations on other icons located outside the operation reception area A201 (A301, A401) or the bar icon display area A202 (A302, A402) will be invalid, thereby preventing users from making accidental operations on those icons.

[0096] In particular, in the above embodiment, the user is notified of the start of bar slide control by displaying an icon F20 (F30, F40) which includes the pointer F22 (F32, F42) that the user is trying to operate. Therefore, the user can intuitively recognize that bar slide control has started and that the pointer F22 (F32, F42) can be moved by a swipe operation.

[0097] Furthermore, in the vehicle display device 1 according to the above embodiment, the bar icon display area A202 (A302, A402) is set to an area that does not overlap with the operation reception area A201 (A301, A401), and even after the bar icon F20 is displayed, the operation reception area A201 Within (A301, A401), function icons F1 to F8 are continuously displayed. This allows the user to recognize the type of control parameter they are operating, improving usability.

[0098] Furthermore, in the vehicle display device 1 according to the above embodiment, when the condition is met that a swipe operation is performed consecutively with a touch operation to display the operation reception area A201 (A301, A401), bar slide control is started. Therefore, the user can change the position and control parameters of the pointer F22 (F32, F42) with a simple operation of swiping with a finger or the like that has come into contact with the operation reception area A201 (A301, A401).

[0099] Furthermore, in the vehicle display device 1 according to the above embodiment, a touch operation is performed to display the operation reception area A201 (A301, A401), and the bar icon F20 (F30, F Even if the swipe operation after displaying 40) is not consecutive, the bar icon F20 (F30, F If the condition is met that a swipe operation is performed using a point within the bar icon display area A202 (A302, A402) as the starting point after the display of 40), then bar slide control will start.

[0100] Therefore, the user presses the bar icon F20 (F30, F Even if you remove your finger or other object from the operation reception area A201 (A301, A401) immediately after the display of 40), the operation reception area A201 will be reactivated in order to start the bar slide control. (A301, A401) There is no need to perform touch operations. Therefore, convenience is improved.

[0101] Furthermore, in the vehicle display device 1 according to the above embodiment, the amount of movement of the pointer F22 (F32, F42) is determined based solely on the amount of change in the left-right direction of the swipe operation position.

[0102] Therefore, as described above, even if the operating position shifts vertically in a way unintended by the user due to vibrations of the vehicle V, this shift can be prevented from affecting the amount of movement of pointer F22 (F32, F42). Consequently, the position of pointer F22 (F32, F42) and, consequently, the control parameters can be changed more reliably in accordance with the user's intentions.

[0103] In particular, in the vehicle display device 1 according to the above embodiment, the longitudinal direction of the bar F21 (F31, F41) but, This direction is left-right and coincides with the direction that determines the movement amount of pointer F22 (F32, F42). Therefore, users can easily recognize the direction that determines the movement amount of pointer F22 and perform swipe operations to move pointer F22 intuitively.

[0104] Furthermore, in the vehicle display device 1 according to the above embodiment, the pointer F22 (F32, F42) is configured to move only within the range between the left and right ends of the bar F21 (F31, F41). Even when a swipe operation is performed to move the pointer F22, any swipe operation performed when the pointer F22 (F32, F42) has reached one end of the bar F21 (F31, F41) in the left-right direction is invalidated. As a result, the pointer F22 (F32, F42) can be displayed more appropriately on the bar F21 (F31, F41).

[0105] Furthermore, in the vehicle display device 1 according to the above embodiment, the air conditioning equipment 60 and the sound equipment 70 are set as the devices to which bar slide control is implemented, and the air conditioning airflow rate, air conditioning temperature, and speaker volume are set as control parameters. Therefore, it is possible to ensure good operability of the air conditioning airflow rate and air conditioning temperature while securing an area for displaying information other than information related to the air conditioning airflow rate, air conditioning temperature, and speaker volume.

[0106] Furthermore, in the vehicle display device 1 according to the above embodiment, the size of the operation reception area A201 (A301, A401) in the left-right direction is set to be approximately the same width as 0.5 index fingers of an average-sized adult American male (AM50) on each side, wider than the area where the corresponding icon F2 (F3, F4) functions as an operator. Double V Even if the user's finger or other body part shifts from the position of the corresponding icon F2 (F3, F4) due to vibration or other reasons, the bar icon F20 (F30, F40) can be displayed, and the bar slide control can be initiated.
