Control device, control method, program, and display unit

This disclosure relates to a control device, a control method, a program, and a display unit.

2. Description of the Related Art A navigation device that displays a map image at a desired position according to an operation of a user such as an occupant on a display device using map image data and coordinate data is known. In recent years, with the widespread use of touch panels, user operations via touch panels provided so as to cover the display area of display devices are becoming mainstream for navigation devices.

The cover panel that covers the touch panel often has a mirror surface. Therefore, dirt such as fingerprints attached to the cover panel during operation of the touch panel is easily noticeable. Therefore, it is often necessary to wipe off dirt adhering to the cover panel with a cloth or the like. If such a wiping operation is performed during operation of the navigation device, the touch panel may also react to the wiping operation, resulting in erroneous input to the navigation device. A technique for preventing such erroneous input has been proposed (see Patent Document 1).

Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

(First embodiment)
Hereinafter, an example of the configuration of the control device according to the present disclosure will be described with reference to FIGS. 1 to 5. The control device according to the present disclosure will be described by taking an in-vehicle navigation device that displays a navigation screen or the like using a map as an example.

FIG. 1 is a diagram showing an example of the appearance of the navigation device A according to the present embodiment. FIG. 2 is a diagram illustrating an example of a hardware configuration of the navigation apparatus A according to the present embodiment. FIG. 3 is a diagram illustrating an example of functional blocks of the control device 1 according to the present embodiment. FIG. 4 is an exploded perspective view showing an example of a component configuration of the display unit 3 according to the present embodiment. FIG. 5 is a cross-sectional view showing an example of the component configuration of the display unit 3 according to the present embodiment.

<Configuration of navigation device>
The navigation device A includes a control device 1, a storage device 2, and a display unit 3. For example, the control device 1 and the storage device 2 generate map image data, and the display unit 3 displays the map image, thereby providing a navigation function to a user such as an occupant.

The control device 1 includes, for example, a CPU (Central Processing Unit). And the control apparatus 1 performs data control with each part of the navigation apparatus A, and centrally controls the navigation function provided to a user, when CPU runs a computer program.

The control device 1 has a control circuit 1A. The control circuit 1A has functions of a display control unit 1a, a press information acquisition unit 1b, a touch sensor information acquisition unit 1c, and an operation mode switching unit 1d. Moreover, the control apparatus 1 has the press information input part 1e into which press information is input, and the touch sensor information input part 1f into which touch sensor information is input. The display control unit 1a, the press information acquisition unit 1b, the touch sensor information acquisition unit 1c, and the operation mode switching unit 1d are realized, for example, when the CPU executes an application program (see FIG. 3. These functions are provided). Details of the operation used will be described later with reference to FIG.

The display control unit 1a uses the map image data stored in the storage device 2 to generate and display a map image to be displayed on the display unit 3 (display device 3a). The display control unit 1a is based on information such as information indicating that a touch operation acquired by the touch sensor information acquisition unit 1c has been detected, information indicating a touch position, position information acquired from a GPS (Global Positioning system) terminal 4, and the like. Then, the display device 3a is controlled. Here, the touch operation is an operation in which the user touches the finger in the display area of the display device 3a. The touch position is a position where the user's finger contacts in the display area of the display device 3a.

The press information acquisition unit 1b acquires information indicating the pressure (press) applied to the display area of the display device 3a detected by the pressure sensor 3c from the display unit 3 (pressure sensor 3c) via the press information input unit 1e. To do. In one example, the information indicating the pressure is a voltage signal output from the pressure sensor 3c. In another example, the information indicating the pressure is a current signal output from the pressure sensor 3c.

The touch sensor information acquisition unit 1c acquires information indicating that a touch operation has been detected and information indicating a touch position from the touch sensor 3b via the touch sensor information input unit 1f. Information indicating the touch position is output as a value from the touch sensor 3b (display unit 3) to a register included in the control device 1, for example. Then, the touch sensor information acquisition unit 1c acquires information indicating the touch position based on the value stored in the register.

In one example, the touch sensor information acquisition unit 1c determines whether or not a swipe operation has been performed in the display area of the display device 3a based on information indicating the touch position. Here, the swipe operation is an operation in which the user traces the surface of the cover panel 3e with a finger in the display area of the display device 3a.

The operation mode switching unit 1d activates the operation mode of the display unit 3, the first operation mode (cleaning mode) in which the response of the display device 3a to the touch operation is invalidated, and the response of the display device 3a to the touch operation. Is switched to the second operation mode (normal operation mode).

In the cleaning mode, the display device 3a does not respond to a touch operation on any part of the display area of the display device 3a, so that the user can display the navigation device A without worrying about the malfunction of the navigation device A. The display area of the device 3a can be cleaned. On the other hand, in the normal operation mode, for example, the navigation device A provides the above navigation function to the user.

The storage device 2 includes, for example, a ROM (read-only memory), a RAM (random-access memory), an HDD (hard disk drive), and the like, and includes a system program, an application program that can be executed on the system program, and the like. These various processing programs and various data are stored, and a work area for temporarily storing them in the arithmetic processing is formed. In addition to the HDD, the storage device 2 may be stored in an auxiliary storage device using a flash memory or the like so as to be read / write updated. Various processing programs and various data may be downloaded through an Internet line.

The display unit 3 includes a display device 3a, a touch sensor 3b, and a pressure sensor 3c (see FIGS. 4 and 5). The display unit 3 can switch the operation mode between the cleaning mode and the normal operation mode.

The display device 3a is constituted by a liquid crystal display, for example, and displays a map image or the like in the display area of the liquid crystal display. Image data is input from the control device 1 to the display device 3a, and a map image or the like is displayed based on the image data.

The touch sensor 3b is a user input device for the navigation device A. The touch sensor 3b detects the touch operation by the user by detecting whether or not the user's finger contacts the surface of the cover panel 3e in the display area of the display device 3a.

As the touch sensor 3b, for example, a projected capacitive touch sensor is used, and a plurality of capacitances are arranged in a matrix on the display area of the display device 3a by X electrodes and Y electrodes arranged in a matrix. A sensor is configured. Then, the touch sensor 3b detects a change in capacitance due to capacitive coupling generated between the electrodes and the finger when the finger approaches the touch sensor 3b. An operation is detected and a touch position is specified. Then, the touch sensor 3b outputs information indicating that the touch operation has been detected and information indicating the touch position to the control device 1.

The pressure sensor 3c detects a pressure applied to the display area of the display device 3a. In one example, the pressure-sensitive sensors 3c are arranged at four positions at positions corresponding to the four sides of the outer periphery of the display area of the display device 3a.

In one example, the pressure-sensitive sensor 3c detects a pressure based on a capacitance that changes according to the distance between electrodes provided on each of the pressure-sensitive members that are provided above and below. In another example, the pressure-sensitive sensor 3c detects a pressure based on a resistance value that changes in accordance with a contact area between a resistor and a current-carrying circuit provided on each of the pressure-sensitive members provided above and below.

Information indicating the pressure detected by the pressure sensor 3 c is output to the control device 1. In one example, the information indicating the pressure is a voltage signal between the electrodes provided on each of the pressure-sensitive members. In another example, the information indicating the pressure is a current signal of an energization circuit provided in the pressure sensitive member.

Furthermore, the display unit 3 includes a housing 3d, a cover panel 3e, and a double-sided tape 3f in addition to the display device 3a, the touch sensor 3b, and the pressure sensor 3c.

Specifically, the display unit 3 includes a plate-like touch sensor 3b and a cover panel so that the display device 3a is accommodated in the housing 3d so that the display region is exposed, and covers the display region of the display device 3a. 3e are arranged and arranged in this order. And the plate-shaped touch sensor 3b is being fixed with respect to the housing | casing 3d using the double-sided tape 3f in the outer side of the outer edge part of the display area of the display apparatus 3a. The pressure sensor 3c is installed between the plate-shaped touch sensor 3b and the housing 3d on the outer periphery of the display area of the display device 3a.

The navigation device A includes a GPS (Global Positioning System) terminal 4, a gyro sensor 5, a vehicle speed sensor 6, a TV (television) receiver 7, a radio receiver 8, and a CD / DVD (compact disc / digital versatile tile disc) reproducing device. 9. It has a connection port 10 for connecting a digital audio player, etc., and the control device 1 is configured to allow data communication with these devices. In addition, since these apparatuses are all well-known, detailed description here is abbreviate | omitted.

<Example of mode switching process in navigation device>
FIG. 6 is a flowchart showing an example of the operation of the navigation apparatus A according to the first embodiment. This process is realized by the CPU of the navigation device A reading and executing a program stored in the ROM, for example, when the engine of the host vehicle is started.

In step S1, the control device 1 acquires information indicating the pressure applied to the display area of the display device 3a detected by the pressure sensor 3c (processing as the press information acquisition unit 1b). In one example, the information indicating the pressing is a voltage signal. In another example, the information indicating the pressing is a current signal. In step S <b> 2, the control device 1 calculates the pressure based on the information indicating the pressure acquired from the pressure sensor 3 c (processing as the pressure information acquisition unit 1 b).

In step S3, the control device 1 determines whether or not the pressure is greater than the first threshold value (processing as the operation mode switching unit 1d).

For example, the user cleans the display unit 3 by wiping off dirt adhering to the cover panel 3e in the display area of the display device 3a using a cloth or the like. In that case, a larger pressure is applied to the display area of the display device 3a than a pressure applied by a normal touch operation. Therefore, the pressure sensor 3c detecting a pressure greater than the first threshold is a (necessary) condition for switching the operation mode of the display unit 3 to the cleaning mode.

If it is determined that the pressure is greater than the first threshold (step S3: Yes), the control proceeds to step S4. On the other hand, when it determines with a press not being larger than a 1st threshold value (step S3: No), control returns to step S1.

Thus, since the control does not proceed to step S4 and thereafter while the user performs a normal touch operation, the display unit 3 cannot be switched to the cleaning mode while the normal touch operation is performed in the normal operation mode. . Therefore, it is possible to prevent the user from switching the display unit 3 to the cleaning mode by mistake.

In step S4, the control device 1 determines whether or not a touch operation has been detected (touch sensor information acquisition unit 1c). If it is determined that the touch operation has not been detected (step S4: No), the control proceeds to step S6. In this case, the touch operation is not detected while the pressure is larger than the first threshold value. For example, this is the case when the user presses the display unit 3 through a thick cloth for cleaning. Details will be described later with reference to FIGS. 7A and 7B.

On the other hand, when it is determined that the touch operation is detected (step S4: Yes), in step S5, the control device 1 determines whether or not the swipe operation is detected (processing as the touch sensor information acquisition unit 1c). If it is determined that a swipe operation has been detected (step S5: Yes), the control proceeds to step S6. In this case, the touch operation and the swipe operation are detected while the pressure is larger than the first threshold. For example, this is the case when the user wipes off the display area of the display device 3a through a thin cloth for cleaning. Details will be described later with reference to FIGS. 8A and 8B.

On the other hand, when it is determined that the swipe operation has not been detected (step S5: No), the control returns to step S1. Accordingly, even if a touch operation is detected, if it is determined that the swipe operation is not performed, the switching to the cleaning mode is suppressed, so that it is displayed when it is determined that the user is not willing to wipe off the dirt. It is possible to prevent the unit 3 from being unnecessarily switched to the cleaning mode.

In step S6, the control device 1 switches the operation mode of the display unit 3 from the normal operation mode to the cleaning mode (processing as the operation mode switching unit 1d).

In one example, in the cleaning mode, the control device 1 cuts off the power supply to the touch sensor 3b. Thereby, the control apparatus 1 can invalidate the response of the display apparatus 3a to the touch operation of the touch sensor 3b. In the first embodiment, among the components of the display unit 3, the power supply to the pressure sensor 3c is continued.

In one example, in the cleaning mode, the control device 1 cuts off the power supply to the display device 3a. Also by this, the control apparatus 1 can invalidate the response of the display apparatus 3a to the touch operation of the touch sensor 3b. Further, since the power supply to the display device 3a is cut off, the display device 3a becomes a black screen, and the dirt attached to the cover panel 3e in the display area of the display device 3a is easy to see, so that cleaning becomes easier. .

In yet another example, in the cleaning mode, the control device 1 invalidates the response of the display device 3a to the touch operation of the touch sensor 3b, and displays a screen of an arbitrary color (for example, white) on the display device 3a. It may be displayed. The display device 3a displays a screen of a color that makes it easy to see the dirt in accordance with the type of dirt attached to the cover panel 3e in the display area of the display device 3a, thereby facilitating cleaning.

In one example, when the control device 1 switches the display unit 3 to the cleaning mode, the display control unit 1a notifies the user that the display unit 3 is switched to the cleaning mode for the first period. Is displayed. Here, the first period is a period that is considered necessary for the user who has viewed the display screen to recognize the switching to the cleaning mode. For example, the first period is 1 second, for example.

For example, the display control unit 1a causes the display unit 3 to display a message “switch to cleaning mode” for 1 second. In another example, when the control device 1 switches the display unit 3 to the cleaning mode, the control device 1 makes a voice message “switch to the cleaning mode” from a speaker (not shown). Thereby, the user who is going to clean the display unit 3 of the control apparatus 1 can recognize reliably that the display unit 3 was switched to the cleaning mode, and can prevent the erroneous operation by the user in a normal operation mode. it can.

In step S7, the control device 1 acquires information indicating the pressure detected by the pressure sensor 3c (processing as the pressure information acquisition unit 1b). Next, in step S8, the control device 1 calculates a press based on the acquired information indicating the press (a process as a process as the press information acquisition unit 1b). The contents of the processes in steps S7 and S8 are the same as the contents of the processes in steps S1 and S2.

In step S9, the control device 1 determines whether or not the pressure detected by the pressure sensor 3c is smaller than a predetermined second threshold during the second period (processing as the operation mode switching unit 1d). ).

Here, the second period and the second threshold are thresholds used for determining whether or not the display unit 3 is cleaned by the user. In one example, the second threshold is equal to the first threshold.

The second period is a threshold used for determining whether or not the display unit 3 is cleaned by the user. The second period is, for example, 3 seconds.

When it is determined that the pressure detected by the pressure sensor 3c is smaller than the second threshold during the second period (step S9: Yes), the control proceeds to step S12.

On the other hand, when it is determined that the pressure detected by the pressure-sensitive sensor 3c is not smaller than the second threshold during the second period (step S9: No), the control proceeds to step S10. For example, when the second period is 3 seconds, the cloth is temporarily removed (for less than 3 seconds) from the display area of the display device 3a while the user is cleaning the display unit 3 in the cleaning mode. Even in this case, the display unit 3 can be prevented from being unnecessarily switched to the normal operation mode.

In step S10, the control device 1 determines whether or not the pressure detected by the pressure sensor 3c is greater than a third threshold (processing as the operation mode switching unit 1d). Here, the third threshold value is a threshold value used for determining whether or not the pressure is large enough to cause damage or failure of the display unit 3. For example, the third threshold value is an arbitrary value larger than the first threshold value.

If it is determined that the pressure is not greater than the third threshold (step S10: No), the control returns to step S7.

On the other hand, when it determines with a press being larger than a 3rd threshold value (step S10: Yes), control progresses to step S11. In step S11, the control device 1 causes the display unit 3 to display a predetermined warning screen (processing as the display control unit 1a). The predetermined warning screen includes, for example, a message such as “An excessive push-in has been detected” or “Please note that it may cause damage / failure”. By displaying a warning screen for the user who applies excessive pressure to the display unit 3, the user can recognize that the pressure applied to the display unit 3 is excessive. In another example, the control device 1 utters these messages as voice messages from a speaker (not shown). Control then returns to step S7.

In step S12, the control device 1 switches the display unit 3 from the cleaning mode to the normal operation mode (processing as the operation mode switching unit 1d). Thereby, it can be detected that the user has finished cleaning the display unit 3, and the display unit 3 can be returned to the normal operation mode. In one example, the control device 1 stores the operation state of the display unit 3 immediately before switching from the normal operation mode to the cleaning mode, for example, in the storage device 2 and returns to the normal operation mode. To restore.

In one example, the first threshold is variable. For example, in response to an instruction received by the display unit 3 in the normal operation mode, the control device 1 changes the first threshold value. For example, the display control unit 1a causes the display unit 3 to display a user interface screen including a slider, a list box, and the like for accepting a change in the first threshold value. Next, the display unit 3 receives a user input from the user interface screen. Next, in response to a user input from the user interface screen, the operation mode switching unit 1d changes the first threshold value. If it carries out like this, the press suitable for the cleaning of the display unit 3 according to each user can be set to the control apparatus 1. FIG. The same applies to the second threshold value, the third threshold value, the first period, and the second period.

In one example, the first threshold value is a value larger than the maximum value of pressure that can be detected by the pressure-sensitive sensor 3c when the user swipes the display unit 3 in the normal operation mode.

In one example, when an operation including both pressing and swiping operation is defined in an application that operates on the navigation device A, the first threshold value is larger than the pressing threshold value when the operation is detected. is there.

FIG. 7A is a front view showing a state in which the display area of the display unit 3 is wiped with a thick cloth C1. FIG. 7B is a side view showing a state in which the display area of the display unit 3 is wiped with a thick cloth C1. For cleaning, the user presses the display unit 3 via the thick cloth C1. In this case, the pressure applied by the user is applied to the pressure sensor 3c through the cover panel 3e. Therefore, the pressure-sensitive sensor 3c can detect the pressure applied by the user as it is. Even if the user moves the thick cloth C1 in the direction of the arrow shown in FIG. 7A, the pressure is detected as it is.

On the other hand, as shown in FIG. 7B, even when the user presses the display unit 3 via the thick cloth C1, the touch operation is not detected because the distance from the user's hand to the touch sensor 3b is far. .

FIG. 8A is a front view showing a state of wiping the display area of the display unit 3 with a thin cloth C2. FIG. 8B is a side view showing a state where the display area of the display unit 3 is wiped with the thin cloth C2. For cleaning, the user presses the display unit 3 via the thin cloth C2. In this case, the pressure applied by the user is applied to the pressure sensor 3c through the cover panel 3e. Therefore, the pressure sensor 3c can detect the pressure applied by the user as it is, as in the case of the thick cloth C1. Even if the user moves the thin cloth C2 in the direction of the arrow shown in FIG. 8A, the pressure is detected as it is.

On the other hand, as shown in FIG. 8B, when the user presses the display unit 3 through the thin cloth C2, the user's hand approaches the touch sensor 3b, and thus a touch operation is detected. Further, when the user moves the thin cloth C2 in the arrow direction shown in FIG. 8A, a swipe operation is detected.

As described above, the control device 1 controls the display unit 3. The display unit 3 includes a display device 3a, a touch sensor 3b that detects a touch operation in the display area of the display device 3a, and a pressure-sensitive sensor 3c that detects a pressure applied to the display area. The control device 1 includes an input unit (press information input unit 1e, touch sensor information input unit 1f) to which information indicating pressing and information indicating a touch operation are input, and a control circuit 1A. The control circuit 1A determines the operation mode of the display unit 3 according to the information indicating the press and the touch operation, the first operation mode (cleaning mode) in which the response of the display device 3a to the touch operation is invalidated, and the touch operation. Is switched between the second operation mode (normal operation mode) in which the response of the display device 3a is validated.

According to the control device 1 according to the first embodiment, the response of the display device 3a to the touch operation is invalidated by an easy configuration of detecting the pressing of the display unit 3 on the display area and the touch operation. Can do. As a result, the display unit 3 operating in the normal operation mode can be switched to the cleaning mode through a user's natural and indispensable operation of cleaning such as pressing a cloth or the like against the display area of the display unit 3. Therefore, it is possible to reduce the user's stress when cleaning the display unit 3. Further, when the user cleans the display area of the display unit 3, it is possible to prevent the touch sensor or the pressure sensitive sensor from malfunctioning.

(Second Embodiment)
FIG. 9 is a flowchart showing an example of the operation of the navigation apparatus A according to the second embodiment. The processing contents of steps S1 to S5 shown in FIG. 9 are the same as the processing contents of steps S1 to S5 shown in FIG.

In step S6 ', the control device 1 turns off the navigation device A. When the power of the navigation device A is turned off, the power supply to the display unit 3 is also cut off. Therefore, the control device 1 can invalidate the response of the display device 3a to the touch operation of the touch sensor 3b. In another example, in the cleaning mode, the control device 1 cuts off the power supply to the display unit 3.

In the second embodiment, the user can use the navigation device A by turning on the power of the navigation device A after cleaning the display unit 3.

Thus, the control device 1 according to the second embodiment cuts off the power supply to the display unit 3 in the cleaning mode.

According to the control device 1 according to the second embodiment, the power supply to the display device 3a is interrupted along with the power supply to the display unit 3, whereby the display device 3a becomes a black screen. In the display area of the display device 3a, the dirt attached to the cover panel 3e can be easily seen, so that cleaning becomes easier.

(Other embodiments)
In the first embodiment and the second embodiment, the pressure sensor 3c detects a pressure greater than the first threshold as a condition for switching the operation mode of the display unit 3 to the cleaning mode. . Instead, the user's finger pressing the display unit 3 and the touch sensor 3b based on the relationship between the change in capacitance detected by the capacitance sensor of the touch sensor 3b and the pressure detected by the pressure sensor 3c. The control device 1 estimates the interval between the two. Next, an embodiment in which the control device 1 switches the operation mode of the display unit 3 to the cleaning mode when the estimated interval is larger than a predetermined distance is also conceivable. Here, the predetermined distance is, for example, an arbitrary distance between 0.5 mm and 1 mm. If it carries out like this, when the cloth is pinched | interposed between the user's finger | toe which presses the display unit 3, and the touch sensor 3b, the operation mode of the display unit 3 can be switched to cleaning mode.

In the above embodiment, the cleaning mode is defined for the display unit 3. Instead of this, the cleaning mode may be defined for the control device 1 or the navigation device A in the same manner as defined for the display unit 3.

In the above embodiment, the control device 1 functions as the display control unit 1a, the press information acquisition unit 1b, the touch sensor information acquisition unit 1c, and the operation mode switching unit 1d when the CPU executes the computer program. Is realized.
