[Embodiment]
(Outline of air conditioner 1)
FIG. 1A is a schematic diagram illustrating an example of an air conditioner according to the embodiment, and FIG. 1B is an example of a block diagram of the air conditioner. FIG. 2A is a schematic diagram illustrating an example of a main screen of the air conditioner according to the embodiment, and FIG. 2B is a schematic diagram illustrating an example of a function screen of the air conditioner. Fig.3 (a)-FIG.3 (d) are the schematic for demonstrating an example of operation with respect to the operation part of the air conditioning apparatus which concerns on embodiment.

FIG. 3A shows the target rotation angle θ ₁ . FIG. 3B shows the rotation angle θ ₂ by the first rotation operation. FIG. 3 (c), to rotate until the rotational angle theta ₁ object shows how distant the operation finger 9 from the operation knob 20 dimensional worlds the operation knob 20. FIG. 3D shows a state in which the operation knob 20 is changed and the rotation operation is additionally performed by the rotation angle θ ₃ minutes so that the target rotation angle θ ₁ is reached. The rotation angle θ ₁ and the rotation angle θ ₂ are rotation angles from the reference 200. As an example, the rotation angle θ is positive with respect to the reference 200 in the clockwise direction and negative in the counterclockwise direction. Note that, in each drawing according to the embodiment described below, the ratio between figures may be different from the actual ratio. In FIG. 1B, main signals and information flow are indicated by arrows. Furthermore, “A to B” indicating a numerical range is used in the meaning of A or more and B or less.

  The electronic device of this Embodiment is the air conditioner 1 shown to FIG. 1 (a) and FIG.1 (b) as an example. The air conditioner 1 is an electronic device mounted on a vehicle, and is configured to send out temperature-adjusted air into the vehicle interior. The electronic device is not limited to the air conditioner 1 and may be a navigation device, a music playback device, a video playback device, or the like as an example.

  For example, as shown in FIGS. 2A and 2B, the air conditioner 1 switches the display from the main screen 40 that is the default screen to the function screen 45 when the operation finger 9 contacts the operation unit 2. It is configured as follows. The air conditioner 1 is configured so that the display is switched from the function screen 45 to the main screen 40 when the operation finger 9 is not detected.

  In addition, the air conditioner 1 suppresses the transition from the function screen 45 to the main screen 40 when the operator does not intend to move the operation unit 2 in order to increase the rotation amount of the operation unit 2. The display switching timing when the operating finger is separated from the operation unit 2 is changed.

  Specifically, for example, the air conditioner 1 detects the contact of the operating finger and sets a value related to the function assigned based on the operation performed as shown in FIGS. 1 (a) and 1 (b). The operation unit 2 to be changed, the acceleration calculation unit 3 that calculates the acceleration of the operation performed on the operation unit 2, and the function related to the function assigned from the main screen 40 when contact of the operation finger with the operation unit 2 is detected When the screen 45 is changed and the touch of the operating finger is no longer detected, the display unit 4 is controlled to change from the function screen 45 to the main screen 40, and even if the operating finger is not detected based on the calculated acceleration, And a control unit 6 that displays the function screen 45 without returning to the main screen 40 for a predetermined time T.

  The air conditioner 1 is calculated because the acceleration of the operation is small during an operation that is performed by the operator without releasing the operating finger from the operation unit 2, that is, an operation that is carefully performed to operate to the target setting value. When the acceleration is small, the normal switching timing is used. In the air conditioner 1, since the operation acceleration is large in an operation performed by the operator separating the operation finger from the operation unit 2 in a short time, that is, an operation performed quickly to increase the rotation amount, the calculated acceleration is If it is larger, the function screen 45 is continuously displayed for a predetermined time T instead of the normal switching timing. The air conditioner 1 is not related to the operation unit 2 that has been operated, but when the contact of the operation finger is detected in the other operation unit 2, the air conditioner 1 is related to the other operation unit 2 even within the predetermined time T. The display is switched to the function screen 45 of the function to be performed.

The air conditioner 1 switches the display to the main screen 40 immediately after the operating finger leaves the operation unit 2 when the calculated acceleration (angular acceleration described later) α ≦ Xdeg / s ² (X: arbitrary value) (normally) Switching timing). Further, when the calculated acceleration α> X, the air conditioner 1 switches the display to the main screen 40 after setting a predetermined time T and time lag after the operating finger is released. This predetermined time T is, for example, 300 to 500 ms.

  The air conditioner 1 also includes, for example, a display unit 4 that displays a main screen 40 and the like, and an air conditioning control mechanism unit 5 that generates temperature-adjusted air and sends out air from a selected outlet. .

  For example, the operation unit 2 is configured so that the set temperature can be changed as a value (set value) related to the assigned function based on the performed operation. The location of the air outlet, the mode, etc. may be changed.

(Configuration of operation unit 2)
As an example, the air conditioner 1 is disposed obliquely forward as viewed from an operator sitting in a driver seat or a passenger seat. The air conditioner 1 includes an operation unit 2 on the driver's seat side and an operation unit 2 on the passenger seat side.

  The air conditioner 1 is configured to switch the display to a function screen 45 related to the set temperature when the operator touches the operation unit 2. As an example, the operation unit 2 is configured so that 24 levels of moderation are set, and the set temperature can be set in 0.5 ° C. steps. That is, the rotation angle θ of one level of moderation is 15 °. The set temperature changes by 0.5 ° C. every time the operation unit 2 rotates 15 °. Note that the operation unit 2 on the driver's seat side and the passenger's seat side have the same basic configuration, and therefore the operation unit 2 on the driver's seat side will be mainly described below.

  For example, as shown in FIG. 1A, the operation unit 2 detects a rotatable operation knob 20, a touch sensor 22 that detects an operation finger 9 that contacts the operation knob 20, and a rotation amount of the operation knob 20. And a rotation amount detection unit 24 that is configured to be roughly configured. For example, as shown in FIG. 1A, the operation knob 20 is disposed with the display unit 4 disposed on the surface of the housing 10 interposed therebetween.

  The operation knob 20 has a cylindrical shape, and a touch sensor 22 is disposed on the inner side surface. For example, the operation knob 20 is configured to be rotatable in the left-right direction indicated by an arrow on the plane of FIG. 1A, in other words, counterclockwise and clockwise.

  The touch sensor 22 is, for example, a capacitive sensor that detects an operation finger that has touched the operation knob 20. The touch sensor 22 is configured to detect a single touch as an example, but is not limited thereto, and may be configured to detect multi-touch.

The touch sensor 22 outputs to the control unit 6 a detection result of the operation finger as a detection signal S _1. Control unit 6, the contact of the operating finger on the basis of the detection signals S ₁ to be input, is configured to determine the non-contact.

The rotation amount detection unit 24 is, for example, a sensor that detects the rotation amount (rotation angle θ) of the operation knob 20. The rotation amount detection unit 24 detects the rotation amount using a sensor that detects the rotation amount using light or a change in magnetic field. Sensor. Rotation amount detection unit 24, the detected amount of rotation, i.e. is configured to output to the controller 6 the information of the rotation angle θ as the rotation amount information S _2.

As a modification, the rotation amount detection unit 24 may be configured to output the set number of moderations as the rotation amount. In this case, the control unit 6 is configured to convert the rotation angle θ of the number of moderation based on the rotation amount information S ₂ acquired.

(Configuration of acceleration calculation unit 3)
The acceleration calculation unit 3 is configured to calculate an angular acceleration α as an acceleration based on the detected rotation amount of the operation knob 20 and a time interval at which the rotation amount is measured. For example, the acceleration calculation unit 3 calculates the angular acceleration α based on the rotation amount detected by the rotation amount detection unit 24, and outputs acceleration information S ₃ that is information based on the calculated angular acceleration α to the control unit 6. It is configured as follows.

  As a modification, the acceleration calculation unit 3 may be integrated with the rotation amount detection unit 24, for example. Further, the acceleration calculation unit 3 may be one or provided for each operation unit 2. Furthermore, the acceleration calculation unit 3 may be configured to calculate the acceleration based on the operation speed of the operation unit 2.

  For example, the acceleration calculation unit 3 calculates the angular acceleration α based on a change in the rotation angle θ in a certain period, and the control unit 6 stores this in time series. For example, when the operating finger is not in contact, the control unit 6 compares the latest stored angular acceleration α with an acceleration threshold 60 described later. Note that the angular acceleration α used for comparison is not limited to the latest, for example, the average angular acceleration from contact to non-contact, the maximum angular acceleration therebetween, the average angular acceleration for a predetermined period, etc. Also good.

(Configuration of display unit 4)
The display unit 4 is schematically configured as a liquid crystal monitor having a rectangular shape, for example. For example, the display unit 4 is configured to change the display based on a display control signal S ₄ output from the control unit 6.

  The display unit 4 includes, for example, a main screen 40 that is a default screen and a plurality of function screens 45 related to functions assigned to each operation unit 2. For example, as shown in FIG. 1A, the main screen 40 includes a central display area 41 that displays the outlet and the current mode, a temperature display area 42 that displays the set temperature on the passenger seat side, and the driver's seat. A temperature display area 43 for displaying the set temperature on the side, and an air volume display area 44 for displaying the air volume.

  For example, as shown in FIG. 2B, the function screen 45 is a screen related to a function assigned to the operation unit 2 in which the operation finger 9 is detected. The function screen 45 includes, for example, a central display area 41 on which a set temperature that is an adjustment target is displayed, and an air volume display area 44.

  For example, as shown in FIGS. 2A and 2B, the display unit 4 detects the operation finger 9 when the operation unit 2 on the driver's seat side has a function of adjusting the set temperature on the driver's seat side. Then, the display is switched from the main screen 40 to the function screen 45. The set temperature displayed in the central display area 41 of the function screen 45 changes according to the rotation of the operation knob 20.

(Configuration of air conditioning control mechanism 5)
The air-conditioning control mechanism unit 5 has a mechanism that generates air of a set temperature that is set and sends the air at a set air volume from a selected outlet. The air-conditioning control mechanism unit 5 performs selection of the air outlet for delivering air as well as adjusting the temperature and air volume of the air based on the control signal S ₅ output from the control unit 6.

(Configuration of control unit 6)
The control unit 6 includes, for example, a CPU (Central Processing Unit) that performs operations and processes on acquired data according to a stored program, a RAM (Random Access Memory) that is a semiconductor memory, a ROM (Read Only Memory), and the like. Microcomputer. In this ROM, for example, a program for operating the control unit 6, an acceleration threshold value 60, and a time threshold value 61 are stored. The RAM is used, for example, as a storage area for temporarily storing calculation results and acquired angular acceleration α. Further, the control unit 6 has means for generating a clock signal therein, and operates based on this clock signal.

  When the calculated acceleration is equal to or greater than the acceleration threshold value 60, for example, as shown in FIGS. 3A to 3D, the control unit 6 sets the operation knob 20 to increase the rotation amount. It is determined that the operation finger 9 is temporarily detected and the function screen 45 is displayed without returning to the main screen 40 for a predetermined time T.

For example, the control unit 6 has a time threshold value 61 as a predetermined time T, and when the elapsed time after the operation finger 9 is not detected becomes equal to or greater than the time threshold value 61, the function screen 45 is displayed. The display control signal S ₄ for switching the display from the main screen 40 to the main screen 40 is output to the display unit 4. That is, the time threshold 61 is set to generate a time lag for switching from the function screen 45 to the main screen 40.

Here, when the operator greatly changes the set temperature and operates for a rotation angle θ ₁ minute that is difficult to operate at a time (for example, when the rotation operation is performed by more than a dozen degrees of moderation), as an example, FIG. ) And FIG. 3B, the operation knob 20 is first rotated as much as possible. For example, in order to increase the set temperature by 6 ° C., the operator must rotate the operation unit 2 in 12 steps, that is, 180 °.

As an example, as shown in FIG. 3C, the operator once holds the operation finger 9 away from the operation knob 20 so as to be easily rotated. Then, for example, as shown in FIG. 3D, the operator rotates the operation knob 20 again from the first rotation angle θ ₂ to the rotation angle θ ₃ so that the desired angle (rotation angle θ ₁ ) is obtained. Note that θ ₁ = θ ₂ + θ ₃ .

  At this time, since the operation finger 9 is separated from the operation knob 20 in FIG. 3C, the touch sensor 22 does not detect the operation finger 9. However, after that, in FIG. 3 (d), the operator operates the operation knob 20 again. Therefore, when the display transitions from the function screen 45 to the main screen 40 at the timing of FIG. 3 (c), the operator feels bothersome. there is a possibility.

  Therefore, the control unit 6 is configured to switch the display with a time lag without immediately switching from the function screen 45 to the main screen 40 when it is determined that the operation finger is temporarily not detected in order to change the operation unit 2. Has been. As a result, the troublesomeness of the operator to transition from the function screen 45 to the main screen 40 during operation is suppressed.

  Further, since the control unit 6 can be operated without changing when the operator performs a moderation operation of several steps, it is assumed that the operation is finished when the operation finger is released from the operation unit 2, and the normal switching is performed. Switch the display at the timing. As a result, the operator can be prevented from bothering that the display is not switched despite the completion of the operation.

  Below, an example of operation | movement of the air conditioner 1 of this Embodiment is demonstrated according to the flowchart of FIG. Here, a case where the set temperature is changed as the set value will be described as an example.

(Operation)
Control unit 6 of the air conditioning apparatus 1, when the power is turned on, and acquires the detection signals S ₁ from the touch sensor 22. The control unit 6 operates the main screen 40 displayed on the display unit 4 when the “Yes” in Step 1 is established based on the detection signal S ₁ , that is, when the operating finger is detected (Step 1: Yes). finger generates a display control signal S ₄ that to switch to the function screen 45 associated with the assigned to have been operating section 2 detection output to the display unit 4, to switch the display on the function screen 45 from the main screen 40 (Step 2).

Control unit 6, obtained when the rotation of the rotation amount information S ₂ operating knob 20 on the basis of the is detected, generating and air conditioning control a control signal S ₅ to change the set temperature in accordance with the rotation angle θ detected and it outputs the mechanism unit 5, generates and outputs a display control signal S ₄ to change the display of the set temperature on the display unit 4 (Step3). At this time, the number indicating the set temperature displayed in the central display area 41 of the function screen 45 is changed according to the rotation angle θ of the operation knob 20.

When the rotation is detected, the control unit 6 controls the acceleration calculation unit 3 to calculate the angular acceleration α (Step 4). The acceleration calculation unit 3 calculates angular acceleration α based on the acquired rotation amount information S ₂ , generates acceleration information S ₃ corresponding to the calculated angular acceleration α, and outputs it to the control unit 6.

  The control unit 6 compares the angular acceleration α with the acceleration threshold value 60 when the operating finger is not detected, that is, when it is not detected (Step 5: Yes). When the angular acceleration α is larger than the acceleration threshold 60 (Step 6: Yes), the control unit 6 determines that the change is performed and determines from the function screen 45 that the time T is predetermined based on the time threshold 61. The function screen 45 is continuously displayed without switching to the main screen 40 (Step 7).

The control unit 6 is longer than the time threshold 61, when the contact is not detected (Step8: Yes), generates a display control signal _{S 4} for switching the display on the main screen 40 from the functional screen 45 on the display unit 4 The display is switched from the function screen 45 to the main screen 40 (Step 9).

  Here, in step 5, the control unit 6 advances the process to step 3 when the contact of the operation finger is continued (Step 5: No).

  In step 6, if the angular acceleration α is equal to or less than the acceleration threshold value 60 (Step 6: No), the control unit 6 determines that the operation has ended and proceeds to step 9, and proceeds from the function screen 45 to the main screen 40. To switch the display.

  Furthermore, in step 8, when the contact is detected within the time threshold 61 (Step 8: No), the control unit 6 advances the process to Step 3.

(Effect of embodiment)
The air conditioner 1 according to the present embodiment can improve the operability by suppressing troublesomeness during operation. Specifically, the air conditioner 1 determines whether the operation finger has been released in order to change the operation unit 2 when the operation finger is released from the operation unit 2 or whether the operation finger has been released because the operation has been completed. The display switching timing can be changed. Therefore, the air conditioner 1 switches quickly when the operation is finished and wants to quickly return to the main screen 40, and continuously displays the function screen 45 when it is not desired to switch during the operation. Compared with the case where it does not perform, the display according to an operator's intention can be performed, the troublesomeness in operation can be suppressed, and operativity can be improved. In addition, the air conditioner 1 switches the display to the main screen 40 as soon as the operation is completed, and does not switch the display even if the operation finger is released during the operation, that is, sets a time lag for switching the display. Compared to the case where the operator does not, the burden on the operator's recognition can be reduced.

  As another embodiment, the air conditioner 1 may be configured with a touch sensor that can be traced by the operation unit 2. In this case, the air conditioner 1 changes the target set value based on the direction and amount of the tracing operation performed on the operation unit 2. Then, the control unit 6 of the air conditioner 1 determines that the operation is continuously performed when the detected acceleration of the tracing operation is equal to or greater than the acceleration threshold value 60, and from the predetermined time T and the function screen 45, The function screen 45 is continuously displayed without switching to the main screen 40, that is, a time lag is set for switching the display.

  As another embodiment, the air conditioner 1 is configured to determine whether the operation finger 2 is released in order to change the operation unit 2 using speed instead of acceleration, or whether the operation finger is released because the operation is completed. Also good.

  The air-conditioning apparatus 1 according to the above-described embodiment and modification, for example, partially depends on a program executed by a computer, an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), etc. It may be realized.
