[Technical field]

[0001] The present invention relates to a switch device and a control method for the switch device. [Background technology]

[0002] One example of a switch device is a switch device for a vehicle such as an automobile. Some switch devices are disposed separately while others are disposed together on a panel inside the vehicle, taking into consideration the interior design of the vehicle (for example, Patent Document 1).

[0003] This switch device is configured to include a decorative panel, a mask layer having an operation display, an electrode substrate having a sensor electrode of a touch sensor, zebra rubber, and a control substrate.

[0004] An electrode pattern is provided at the end of the mask layer to provide identification information indicating the type of the mask layer. The electrode pattern is connected to the electrode pattern of the control board via zebra rubber, and the identification information included in the electrode pattern is input to the control IC. The control IC changes the control of the function corresponding to the operation display according to the identification information based on the detection signal of the touch sensor.

[0005] According to this switch device, the arrangement of the symbols which are the operation indications of the switch device can be changed by simply replacing the mask layer, and the intended operation corresponding to the operation indication can be performed.

[0013] [First embodiment] Fig. 1 is a configuration diagram of a switch device of design A according to a first embodiment of the present invention. Fig. 2 is a front view of a design panel and an electrode substrate of the switch device of design A according to the first embodiment of the present invention.

Fig. 4 is a configuration block diagram of a switch device according to the first embodiment of the present invention, Fig. 4(a) is a configuration block diagram of switch device 1, and Fig. 4(b) is a configuration block diagram of switch device 2. Fig. 5 is a flow chart of a program of the switch device according to the first embodiment of the present invention.

[0014] 1, a switch device 1 according to a first embodiment of the present invention is composed of an operation panel 10, a capacitance detection unit 40, and a control unit 50. The operation panel 10 and the capacitance detection unit 40, the capacitance detection unit 40 and the control unit 50, and the control unit 50 and the controlled device 100 are electrically connected to each other.

[0015] The operation panel 10 is composed of a design panel 20 that serves as an operation section, and an electrode substrate 30. The operation panel 10 is arranged such that the electrode substrate 30 is superimposed on the rear side of the operator with respect to the design panel 20 on the operator side. For example, the operation panel 10 is provided on the instrument panel of a vehicle.

[0016] The design panel 20 is a translucent plate member made of resin and has a horizontally elongated outer shape.

[0017] 2(a) is a front view of the design panel 20 of design A. As described above, the design panel 20 has a plurality of designs 21 indicating operation functions arranged on both the left and right sides of the design panel 20. The plurality of designs 21 include designs 21 indicating operation positions where an operator touches to operate the switch device 1, and designs 21 that do not indicate operation positions. The design panel 20 of design A has designs 21 indicating 10 operation positions and designs 21 that do not indicate 2 operation positions.

[0018] The individual designs of the multiple designs 21 are: design 221 for increasing air volume setting, design 231 for air volume, design 241 for decreasing air volume setting, design 222 for internal air circulation mode, design 232 for outside air introduction mode, design 242 for fan OFF, design 226 for air conditioning operation, design 236 for front defroster, design 246 for rear defroster, design 227 for increasing air conditioner temperature setting, design 237 for air conditioner temperature setting, and design 247 for decreasing air conditioner temperature setting.

[0019] Among these, the designs other than the air volume design 231 and the air conditioner temperature design 237 are designs 21 indicating the operation position. The air volume design 231 and the air conditioner temperature design 237 are designs 21 not indicating the operation position.

[0020] The electrode substrate 30 is a translucent plate member made of resin, and has an outer shape that is long horizontally to match the design panel 20. However, the outer shape of the electrode substrate 30 is slightly smaller than the design panel 20.

[0021] 2(b) is a front view of the electrode substrate 30. The electrode substrate 30 has a total of 21 electrodes 31 (321-327, 331-337, 341-347) made of transparent electrodes arranged in 3 rows and 7 columns. All of the 21 electrodes 31 are electrically connected to the control unit 50 via the capacitance detection unit 40.

[0022] The electrode substrate 30 has the electrodes 31 facing the design panel 20, and as shown in FIG. 1, the multiple designs 21 of the design panel 20 are overlapped so that their arrangement matches that of the electrodes 31 of the electrode substrate 30.

[0023] Among the multiple electrodes 31, the detection electrodes are electrodes 31 whose arrangement matches the design 21 indicating the operation position. The detection electrodes are electrodes 31 that actually detect the operation and have a function assigned to the controlled device 100. On the other hand, the blank electrodes are electrodes 31 whose arrangement does not match the design 21 indicating the operation position. The detection electrodes are ten electrodes 31, the same number as the designs 21, and the blank electrodes are the remaining eleven electrodes 31. The detection electrodes and blank electrodes have the same specifications, but are electrodes with different functions according to their arrangement relative to the design 21, as described below.

[0024] Of the multiple electrodes 31, the two rows of electrodes on both the left and right ends of Fig. 2(b) are detection electrodes in design A, except for electrodes 331 and 337 in Fig. 2(b) which correspond to the air volume design 231 and the air conditioner temperature design 237 in Fig. 2(a). The other electrodes 31 are blank electrodes in design A.

[0025] That is, electrodes 321, 341, 322, 332, 342, 326, 336, 346, 327, and 347 are detection electrodes in design A. Also, electrodes 331, 337, 323 to 325, 333 to 335, and 343 to 345 are blank electrodes in design A.

[0026] Next, the switch device 2 will be described. The switch device 2 differs from the switch device 1 in that it uses a design panel 25 of design B, as opposed to the switch device 1 that uses the design panel 20 of design A. The design panel 25 of design B differs from the design panel 20 of design A in the number of designs 21 and the arrangement of the designs 21. The rest of the configuration is the same, but the settings of the control unit 50 are slightly different, as described below.

[0027] FIG. 3 is a configuration diagram of a switch device 2 equipped with an operation panel 15 in which a design panel 25 of design B and an electrode substrate 30 are superimposed.

[0028] The design panel 25 of design B has 11 designs 21 and 2 designs 21. And, while the design panel 20 of design A has designs on both the left and right sides and no designs in the center of the left and right, the design panel 25 of design B has designs on both the left and right ends and the bottom of the top and bottom.

[0029] 3, the airflow setting UP design 251, the airflow design 281, the airflow setting DOWN design 261, and the airflow OFF design 271 are arranged at the left end. Also, the internal air circulation mode design 272, the external air introduction mode design 273, the front defroster design 274, the rear defroster design 275, and the air conditioner auto mode design 256 are arranged at the bottom end. Also, the air conditioner temperature setting UP design 257, the air conditioner temperature design 287, the air conditioner temperature setting DOWN design 267, and the air conditioner operation design 277 are arranged at the right end.

[0030] Among these, the designs other than the air volume design 281 and the air conditioner temperature design 287 are designs indicating the operation position 21. The air volume design 281 and the air conditioner temperature design 287 are designs 21 that do not indicate the operation position.

[0031] The electrode substrate 30 has the same specifications as the switch device 1 of the design panel 20 of design A. However, the arrangement of the detection electrodes and blank electrodes of the electrode substrate 30 is different between switch devices 1 and 2. That is, the electrodes 31 whose arrangement matches the design 21 indicating the operation position are assigned a function in the controlled device 100 and become detection electrodes. On the other hand, the electrodes 31 whose arrangement does not match the design 21 indicating the operation position are not assigned a function in the controlled device 100 and become blank electrodes. The arrangement of the detection electrodes and blank electrodes is different due to the difference in the arrangement of the designs indicating the operation positions of designs A and B.

[0032] Fig. 4(a) is a configuration block diagram of switch device 1, and Fig. 4(b) is a configuration block diagram of switch device 2. Switch device 1 and switch device 2 have the same configurations of electrode substrate 30, capacitance detection unit 40, and control unit 50. Switch device 1 and switch device 2 differ in the controlled device 100 connected to the control unit 50 and the layout of the design of the corresponding design panel.

[0033] For example, regarding the electrode 322, in the design panel 20 of the design A, as shown in Fig. 4(a), the arrangement of the electrode 322 coincides with that of the design 222. As shown in Fig. 1, the design 222 is the design 21 indicating the operation position of the recirculated air mode. The electrode 322 has a function assigned to the controlled device 100 in the recirculated air mode indicated by the design 222. And the electrode 322 is a detection electrode.

[0034] 4B, the layout of the electrodes 322 does not match the design of the design panel 25 of design B. The electrodes 322 are not assigned any function to the control target device 100. The electrodes 322 are blank electrodes.

[0035] The electrode 321 is a detection electrode in both switch device 1 and switch device 2, and the electrode 323 is a blank electrode in both switch device 1 and switch device 2.

[0036] The capacitance detection unit 40 is an IC (Integrated Circuit) having an AFE (Analog Front End) that detects capacitance and an A / D converter circuit that converts the detected capacitance into a digital detection value. The capacitance detection unit 40 is electrically connected to all of the multiple electrode units 31. As shown in FIG. 1, the capacitance detection unit 40 receives analog information on the state of all of the electrodes of the multiple electrode units 31 as a signal S1. The capacitance detection unit 40 converts the capacitance, which is a physical quantity of the state of the electrodes 31, into a voltage, digitizes it, and detects it. The detected information is output as a signal S2.

[0037] The capacitance detection unit 40 serving as the detection unit may be provided as a part of the control unit 50 described below. In this case, the signal S2 is exchanged within the control unit 50.

[0038] The control unit 50 includes a microcomputer including a CPU (Central Processing Unit) that performs calculations and processing on acquired data according to stored programs, a RAM (Random Access Memory) that is a semiconductor memory, and a ROM (Read Only Memory).

[0039] The control unit 50 has in advance a threshold value: Vi_th for each electrode 31. The threshold value for the detection electrodes whose arrangement matches the design 21 indicating the operation position is set to a value that serves as a reference for determining whether or not an operation has been performed. On the other hand, the threshold value for the blank electrodes whose arrangement does not match the design 21 indicating the operation position is set to a maximum value. Note that the threshold value does not necessarily have to be set to a maximum value, and may be any large value that cannot actually be obtained.

[0040] In addition, the layout of the design 21 indicating the operation position is different between the switch device 1 of design A and the switch device 2 of design B, and the layout of the detection electrodes and blank electrodes is different. Therefore, the threshold settings for each electrode 31 of the control unit 50 are different between the switch device 1 and the switch device 2.

[0041] 1, the control unit 50 receives a signal S2 from the capacitance detection unit 40. When receiving the signal S2, the control unit 50 does not distinguish between whether each electrode 31 is a detection electrode or a blank electrode, but receives the signals S2 of all electrodes 31. Therefore, the control unit 50 does not require evaluation processing time to distinguish between detection electrodes and blank electrodes. Therefore, the reaction speed of the switch device 1 and the switch device 2 is not slowed down by the evaluation processing time. Furthermore, the control unit 50 does not require memory capacity to distinguish between detection electrodes and blank electrodes.

[0042] Then, based on this input signal S2, the control unit 50 determines each electrode 31 and transmits the signal S3 to the target control device. For each electrode 31, when it is a detection electrode, the control unit 50 actually determines whether there is an "operation" or "no operation" in the design 21 which is the operation unit. On the other hand, when it is a blank electrode, although a determination is made, it is always determined as "no operation". Then, the control unit 50 performs signal transmission according to the determination.

[0043] That is, the determination of the electrode 31 by the control unit 50 and the transmission of the signal S3 are performed as follows according to the flowchart shown in FIG. 5.

[0044] In S00, the control unit 50 starts the program.

[0045] In S01, the control unit 50 inputs the signal S2 from the capacitance detection unit 40. Then, the control unit 50 acquires the value Vi which is the value obtained by converting the capacitance of the electrode into a voltage and digitizing it by the capacitance detection unit 40. Here, i is the number of the electrode 31, ranging from 1 to 21 (the number of electrodes 31). For each electrode 31, regardless of whether it is a detection electrode or a blank electrode, the control unit 50 performs the following program processing in order from i = 1. Note that this program processing is not limited to being processed in order, and parallel processing may also be possible.

[0046] In S02, the control unit 50 checks whether Vi_th < Vi. When it is a detection electrode whose arrangement coincides with the design 21 indicating the operation position, the threshold value Vi_th is set to a value serving as a criterion for determining the presence or absence of an operation. Therefore, the control unit 50 actually checks the "presence or absence of an operation". On the other hand, when it is a blank electrode whose arrangement does not coincide with the design 21 indicating the operation position, the maximum value is set as the threshold value Vi_th. Therefore, the result of the check will not always be Vi_th < Vi.

[0047] And in S02, when Vi_th < Vi, the program proceeds to S03. In S03, the control unit 50 determines "operation exists". And in S04, the control unit 50 transmits an ON signal as signal S3. Then, the program returns to the start of S00.

[0048] On the other hand, in S02, when Vi_th ≥ Vi, the program proceeds to S05. In S05, the control unit 50 determines "no operation". And in S06, the control unit 50 transmits an OFF signal as signal S3. Then, the program returns to the start of S00.

[0049] (Operation of the switch device) When the operator touches the design 21 indicating the operation position of the switch device 1 as a switch operation, the capacitance of the detection electrode that coincides with the design 21 changes. Then, the capacitance detection unit 40 detects the change by signal S1 and outputs signal S2 to the control unit 50. The control unit 50 inputs signal S2, determines "operation exists" by the program, and outputs an ON signal to the controlled device 100. Then, the controlled device 100 operates upon receiving the ON signal from the control unit 50.

[0050] On the other hand, when the operator touches a location other than the design 21 indicating the operation position of the switch device 1, an ON signal is not output to the controlled device 100. That is, even if the capacitance of the electrode 31 changes because there is an electrode 31 on the back side of the touched location, the threshold value of the blank electrode of the control unit 50 has the maximum value set. For this reason, the control unit 50 does not determine "operation exists".

[0051] Note that when the operator is not touching the switch device 1, the capacitance of all the electrodes 31 does not change. For this reason, the control unit 50 does not determine "operation exists".

[0052] Switch device 1 using design panel 20 of design A and switch device 2 using design panel 25 of design B have the same configuration except for the design panels, but the threshold settings for each electrode 31 of control unit 50 are different. Then, both switch device 1 and switch device 2 operate based on this threshold setting. As a result, both switch device 1 using design panel 20 of design A and switch device 2 using design panel 25 of design B operate with the detection electrodes whose arrangement matches the design 21 that indicates the operation position functioning.

[0053] Furthermore, the control of the control unit 50 is performed after inputting signals S2 from all electrodes 31 connected to the control unit 50 via the capacitance detection unit 40, which converts the capacitance of the electrodes into a voltage and acquires a digitalized value Vi. If the control unit 50 were to perform design selection when the signal S2 is input, a processing time would be required for the selection evaluation. Furthermore, a storage capacity for the design selection pattern would be required. However, the switch device 1 and the switch device 2 do not require processing time due to selection when the signal S2 is input, and therefore the response speed of the switch can be maintained. Furthermore, no storage capacity for the design selection pattern when the signal S2 is input is required.

[0054] (Effects of the first embodiment of the present invention) According to the above-described embodiment of the present invention, the following effects can be obtained. (1) The control unit inputs and judges signals from the electrodes without identifying whether they are detection electrodes or blank electrodes. The control unit then transmits the judgment results for each electrode according to the allocation of functions to the controlled device. This makes it possible to omit a configuration for transmitting identification information for changing the control of the function corresponding to the operation display to the control unit. Furthermore, the switch device can easily change the arrangement of the operation display. (2) The setting of blank electrodes that have no detection target is achieved by setting the threshold value of the judgment criterion of the control unit to a large value. This makes it easy to set blank electrodes. In addition, the switch device makes it easy to change the arrangement of the operation display.

[0055] [Second Embodiment] FIG. 6 is a flowchart of a program of the switch device according to the second embodiment of the present invention. In the following description, parts having the same configuration and function as those in the first embodiment are denoted by the same reference numerals.

[0056] This switch device 3 is different from the first embodiment in that the control unit 50 has in advance the setting information of all the electrodes 31 as to whether they are detection electrodes or blank electrodes.

[0057] The control unit 50 performs the following processing on each electrode 31. When the control unit 50 is a detection electrode, it transmits a signal according to the determination. On the other hand, when the control unit 50 is a blank electrode, it does not transmit a signal according to the determination.

[0058] The determination and signal transmission of each electrode 31 of this control unit 50 are made according to the flowchart shown in FIG. 6.

[0059] In S00, the control unit 50 starts the program.

[0060] In S11, the control unit 50 acquires, as the signal S2 from the capacitance detection unit 40, the value Vi obtained by converting the capacitance of the electrode into a voltage and digitizing it by the capacitance detection unit 40.

[0061] In S12, the control unit 50 checks whether Vth < Vi. Since the threshold value Vth is set as a value for determining the presence or absence of an operation, the "presence or absence of an operation" is checked.

[0062] And in S12, when Vth < Vi, the program proceeds to S13. In S13, the control unit 50 determines that "there is an operation". Then the program proceeds to S15.

[0063] On the one hand, in S12, if Vth < Vi does not hold, the program proceeds to S14. In S14, the control unit 50 determines "no operation". Then, the program proceeds to S15.

[0064] In S15, the control unit 50 checks whether the acquired value: Vi is due to the electrode 31 to which the controlled device 100 is assigned. That is, the control unit 50 has in advance the setting information of all the electrodes 31 as to whether they are detection electrodes or blank electrodes. Thereby, the control unit 50 checks whether it is a detection electrode to which the controlled device 100 is assigned.

[0065] Then, in S15, if it is due to the assigned electrode 31, the program proceeds to S16. In S16, the control unit 50 transmits an ON signal or an OFF signal corresponding to the determination in S13 or S14 as the signal S3. Then, the program returns to the start of S00.

[0066] On the other hand, in S15, if it is not due to the assigned electrode 31, the program returns to the start of S00. That is, the control unit 50 does not transmit the signal S3.

[0067] That is, the control unit 50 makes the following determinations in order for each electrode 31. The control unit 50 determines "operation" or "no operation" of the design 21 which is the operation unit for all the electrodes 31. Then, in the case of an electrode with a function assignment, the control unit 50 transmits a signal according to the determination. With this method, when the signal S2 is input, there is no processing time for the control unit 50 to perform selection by the design.

[0068] (Effect of the Second Embodiment of the Present Invention) According to the above-described embodiment of the present invention, the following effects can be obtained. (1) The control unit inputs and judges signals from the electrodes without identifying whether they are detection electrodes or blank electrodes. The control unit then transmits the judgment results for each electrode according to the allocation of functions to the controlled device. This makes it possible to omit a configuration for transmitting identification information for changing the control of the function corresponding to the operation display to the control unit. Furthermore, the switch device can easily change the arrangement of the operation display. (2) The control unit has in advance setting information for all electrodes, indicating whether they are detection electrodes or blank electrodes. When an electrode has an assigned function, the control unit transmits a signal according to the determination. This allows the switch device to easily change the layout of the operation display.

[0069] Although the embodiments of the present invention have been described above, these embodiments are merely examples and do not limit the invention according to the claims. These new embodiments and their modifications can be embodied in various other forms, and various omissions, substitutions, modifications, etc. can be made without departing from the gist of the present invention.

[0070] In the embodiment described above, the electrode substrate 30 and the capacitance detection unit 40 are used as a detection unit, and a configuration is shown in which an operation is detected by a change in capacitance, but the present invention is not limited to this. For example, the switch device may be configured to use a piezoelectric element and detect an operation by a change in potential. Also, for example, the switch device may be configured to detect a mechanical operation, such as when a substrate has an operation unit and an operation detection unit.
