In addition, “A to B” indicating a numerical range is used in the meaning of A or more and B or less.

  The operation input device 1 is disposed on a floor console 53 located between a driver seat 51 and a passenger seat 52 of the vehicle 5 as shown in FIG. The operation input device 1 can operate an electronic device that is electromagnetically connected, for example. In other words, the operation input device 1 is, for example, instructions such as movement and selection of the cursor displayed on the display unit of the electronic device, selection of the displayed icon, determination, dragging, dropping, etc. by operation with a conductive pen or finger. It is configured to be able to do. In this embodiment, an operation with a finger (operation finger) will be described.

  As shown in FIG. 1B, the operation input device 1 includes a touch pad 10 as a touch detection unit, a threshold value generation unit 12, an initial threshold value 200, and thresholds for setting as a touch threshold value. And a control unit 20 having a value 201.

  This threshold value generation unit 12 is set in advance on the operation surface 100 of the touch pad 10 when the controlled device is in a locked state in which an instruction other than a predetermined operation made through the touch pad 10 is not accepted. It is configured to generate a setting threshold value 201 for determining an operation performed on the operation surface 100 based on a peak value of a detection value output from the touch pad 10 in accordance with the operated operation.

  The controlled device is, for example, an electronic device mounted on the vehicle 5 such as the navigation device 56, the air conditioner 57, and the music playback device 58 shown in FIG. For example, the display device 54 is configured to function as a display unit of these electronic devices. In the following embodiment, a case where the controlled device is the navigation device 56 will be described as an example.

  The predetermined operation is, for example, a tap operation that is an operation of hitting the operation surface 100 with an operation finger, but is not limited to this, and a gesture operation for drawing a predetermined figure on the operation surface 100 Etc.

  As an example, the locked state is a predetermined operation such as a tracing operation when a display image 541 that is a map image is displayed on the display screen 540 of the display device 54 as shown in FIG. Even if an operation other than the tap operation is performed on the touch pad 10, the map image is not scrolled or switched to another image. Hereinafter, this lock state is referred to as a screen lock state or a screen lock.

(Configuration of touchpad 10)
The touch pad 10 detects, for example, an electrostatic capacity formed between an electrode disposed below the operation surface 100 and the operation finger when the operation finger of the operator approaches or comes into contact with the operation surface 100. This is a capacitive touch sensor.

Touch pad 10, for example, to the control unit 20 of the electrostatic capacitance is a detected value of one period detected as a detection value information S _1. As an example, the detected value is a digital value obtained by digitally converting an analog value indicating capacitance. The touch pad 10 is configured such that the detected value takes a positive value when an operating finger is detected.

(Configuration of threshold generation unit 12)
The threshold generation unit 12 is configured to set the setting threshold 201 by multiplying a peak value in the detection value used for the tap operation determination by a predetermined constant.

  The detection value for one period described above is such that, for example, an xy coordinate system is set on the operation surface 100, the horizontal axis is x, the vertical axis is y, and the x-axis is orthogonal to the paper surface of FIG. X electrode on the detection side is disposed on the drive side, and the y electrode on the drive side is arranged so as to be orthogonal to the y axis, a plurality of scan electrodes obtained by scanning all combinations of the x electrode and the y electrode It is a detected value.

  FIG. 2C is obtained by combining the drive-side y electrode that obtained the maximum detection value among the detection values of a plurality of periods required for the determination of the tap operation and all the x electrodes. A graph of the capacitance is shown. In the present embodiment, the detection value is increased when the operating finger is detected. Therefore, when the operating finger is detected, the capacitance graph at the coordinates is convex upward. Therefore, the peak value is the maximum value. If the touch pad 10 is configured so that the detected value decreases when the operating finger is detected, a downwardly convex graph is obtained when the operating finger is detected, so the peak value is a negative peak value, that is, the minimum value. It becomes.

Threshold generator 12 generates, for example, set the threshold 201 by multiplying a predetermined constant peak value based on the peak value information S ₂ acquired via the control unit 20. For example, the predetermined constant is preferably a number in the range of 0.6 to 0.9, and more preferably in the range of 0.7 to 0.8. As an example, the predetermined constant is 0.8.

Threshold generator 12 outputs to the control unit 20 the generated set threshold 201 as a threshold value information _{S 3.}

(Configuration of control unit 20)
The control unit 20 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 20, an initial threshold value 200, and a set threshold value 201 are stored. For example, the RAM is used as a storage area for temporarily storing calculation results and the like. Further, the control unit 20 has means for generating a clock signal therein, and operates based on this clock signal.

  The initial threshold value 200 is a threshold value for determining an operation performed on the operation surface 100 when the electronic device is in a screen lock state, for example.

The control unit 20 determines, for example, if the screen locked state, by comparing the detected value information S ₁ and the initial threshold value 200 whether the tap operation. The control unit 20, the result of the comparison, when the tap operation is detected, obtains the peak value from the detection value information S _1, the threshold value generator 12 generates the peak value information S ₂ is the information of the peak value Output to. Control unit 20, when the threshold information S ₃ from the threshold generator 12 is output, and is configured to store a set threshold 201 based on the threshold information S _3. Note that the control unit 20 compares the detection values of a plurality of periods with the initial threshold value 200 in order to determine the tap operation.

Control unit 20, the operation is detected, and outputs the operation is connected to generate operation information S _4, which is information of the coordinate of the xy coordinate system, detected electronic equipment.

The control unit 20 is, for example, as shown in FIG. 1 (b), to obtain the screen lock signal _{S 5.} The screen lock signal S ₅ is output from the connected electronic equipment, the electronic device is a signal indicating whether there the released state whether the screen locked state. Control unit 20, after the screen lock signal S ₅ showing a screen locked state entered, together with determining the presence or absence of the tap operation, and outputs the peak value information S ₂ seeking peak value based on the tap operation.

(Configuration of vehicle communication system 500)
The vehicle communication system 500 is, for example, a system that enables information and signals to be exchanged between electronic devices mounted on the vehicle 5 via a vehicle LAN (Local Area Network) 501.

  For example, as shown in FIG. 2A, the vehicle communication system 500 includes an operation input device 1, a display device 54, a vehicle control unit 55, a navigation device 56, an air conditioner 57, and a music playback device 58. Are electromagnetically connected via the vehicle LAN 501. Note that another electronic device as a controlled device of the operation input device 1 may be electromagnetically connected to the vehicle LAN 501.

  The vehicle control unit 55 is a microcomputer including a CPU, a RAM, a ROM, and the like, for example. The vehicle control unit 55 is configured to comprehensively control electronic devices mounted on the vehicle 5.

  Below, the operation | movement which produces | generates the setting threshold value 201 of the operation input apparatus 1 which concerns on this Embodiment is demonstrated according to the flowchart of FIG.

(Operation)
Operation control unit 20 of the input device 1, screen lock signal S ₅ is input, the detection value and the initial threshold 200 when the electronic device is in a screen lock state (S1), a plurality of acquired detected value information S ₁ Based on the above, the presence / absence of a tap operation is determined.

When it is determined that “Yes” in Step 2 is established, that is, the tap operation is detected (S2: Yes), the control unit 20 obtains a peak value from the detection value used for the determination of the tap operation, and based on the peak value Peak value information S ₂ is generated and output to the threshold value generator 12.

Threshold generator 12, obtained peak value information S peak value of the detection values based on _2, i.e. generated by control to set the threshold 201 multiplied by the predetermined constant to the peak value of the electrostatic capacitance It outputs to the part 20 (S3).

Control unit 20 sets the output to the electronic apparatus generates operation information S ₄ based on the tapping operation, the product was unlock screen state, based on the threshold information S ₃ obtained from the threshold generating unit 12 The threshold value 201 is stored (S4). The control unit 20 determines an operation according to the set threshold value 201. As described above, the operation input device 1 ends the operation of generating the setting threshold value 201 by releasing the screen lock state.

Note the control unit 20, before generating the setting threshold 201, when the screen lock signal S ₅ indicating that the screen locked state is released from the electronic device side is input, terminates the operation of generating the set threshold 201 Then, the operation is determined by the initial threshold value 200.

(Effects of the first embodiment)
Operation input device 1 concerning this embodiment can set up a threshold according to the state at the time of operation. When the operator operates with bare hands and when the operator wears gloves to operate, the detected capacitance differs even for the same operator. Moreover, even if it is a bare hand, the detected electrostatic capacitance changes with individual differences by the difference in the thickness of a finger, etc. As a result, for example, when the threshold value is fixed, there is a possibility that an operation performed with a glove is not detected or an operation performed with a finger thinner than expected is not stabilized and the operability is lowered. If the threshold is set low so that the operation with gloves can be detected, that is, if the detection sensitivity of the operation is set high, the operation is detected in the state of being away from the operation surface in the case of a bare hand, and the operator Unintended unnecessary operations may be performed in the electronic device. However, since the operation input device 1 sets the setting threshold value 201 using the peak value of the detection value based on the tap operation when the screen is locked, the operation input device 1 depends on the state of the hand when the tap operation is performed. An appropriate setting threshold 201 can be set. Further, since the operation input device 1 generates the setting threshold value 201 suitable for the state at the time of operation, the detection sensitivity is appropriate and the operability is good.

  Since the operation input device 1 generates the setting threshold value 200 based on the tap operation performed when the screen is locked, the electronic device is not controlled by an instruction based on the tap operation, which is unnecessary. No action occurs.

The second embodiment is different from the above-described embodiment in that an acceleration sensor for detecting a load applied to the touch pad 10 is provided.

  FIG. 4A is a block diagram showing an example of the operation input device according to the second embodiment, and FIG. 4B shows an example of the operation input device for explaining the arrangement of the acceleration sensors. It is a schematic diagram. In the embodiments described below, parts having the same functions and configurations as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and description thereof is omitted.

  Here, the touchpad may detect the operation finger even if the operation finger is not in contact with the operation surface, depending on a state at the time of operation or a set threshold value. The threshold value set in a state where the operation finger is not in contact with the operation surface is slightly higher than the appropriate detection sensitivity, and it is considered that an unnecessary operation is detected. Therefore, as an example, the operation input device 1 according to the present embodiment detects an acceleration based on a load L applied to the operation surface 100 when an operation with the operation finger 9 is performed, as illustrated in FIG. Thus, the tap operation accompanied by the contact of the operation finger 9 with respect to the operation surface 100 is reliably detected, and the setting threshold value 201 that provides more appropriate detection sensitivity is generated.

The acceleration sensor 14 is, for example, a capacitance type or piezoresistive type acceleration sensor.

The control unit 20, if it is determined that operation on the basis of the sensor signal S ₆ output from the acceleration sensor 14 is made to generate a set threshold 201 controls the threshold generator 12.

The control unit 20 includes a load threshold 202, by comparing the load and the load threshold 202 based on the sensor signal S ₆ obtained, if the load exceeds the load threshold 202, It is determined that the operation finger has touched the operation surface 100, that is, the touch pad 10 has been operated.

Control unit 20, "Yes" is established in step 11, i.e. the operation is determined to have been detected (S11: Yes), followed by the detection values of a plurality of detected value information S ₁ acquired by the initial threshold value 200 The presence or absence of a tap operation is determined based on the above.

Control unit 20 determines that a tap operation is detected (S12: Yes), The peak value from the detection value used for the determination of the tap operation, and generates a peak value information S ₂ based on the peak value threshold Output to the value generator 12.

Threshold generator 12, obtained peak value information S peak value of the detection values based on _2, i.e. generated by control to set the threshold 201 multiplied by the predetermined constant to the peak value of the electrostatic capacitance It outputs to the part 20 (S13).

Control unit 20 sets the output to the electronic apparatus generates operation information S ₄ based on the tapping operation, the product was unlock screen state, based on the threshold information S ₃ obtained from the threshold generating unit 12 The threshold value 201 is stored (S14). The control unit 20 determines an operation according to the set threshold value 201. As described above, the operation input device 1 ends the operation of generating the setting threshold value 201 by releasing the screen lock state.

  If the control unit 20 determines in step 12 that a tap operation is not detected (S12: No), the control unit 20 returns to step 11 and continues the operation.

Note the control unit 20, before generating the setting threshold 201, when the screen lock signal S ₅ indicating that the screen locked state is released from the electronic device side is input, terminates the operation of generating the set threshold 201 Then, the operation is determined by the initial threshold value 200.

(Effect of the second embodiment)

For example, when the operator sits on the driver's seat 51 and touches the operation surface 100, a circuit including the touch pad 10 and the detection electrode 510 is formed through the operator, and the seating seat can be determined.

The seat discrimination sensor 16 generates discrimination information S ₇ that is information on the seat on which the operator is seated and outputs the discrimination information S ₇ to the control unit 20.

  The control unit 20 stores the seat determined by the seat determination sensor 16 in association with the set threshold value, and controls the operation surface according to the result of comparing the set threshold value and the detected value associated with the determined seat. The operation performed on 100 is determined.

  The set threshold value for each seat is, for example, the threshold value 203 for the D seat generated based on the tap operation performed by the operator on the driver's seat side to release the screen lock state, and the passenger seat side P seat threshold value 204 generated based on the tap operation performed by the operator to release the screen lock state.

Threshold generator 12, the obtained peak value of the detection value based on the peak value information S _2, i.e. the control unit generates a set threshold by multiplying a predetermined constant to the peak value of the electrostatic capacitance 20 is output. When the operator is seated in the D seat (S23: D seat), the control unit 20 generates the D seat threshold 203 that associates the generated setting threshold with the determined D seat. (S24).

  Here, when it is determined in step 23 that the operator is seated in the passenger seat (P seat) (S23: P seat), the control unit 20 determines that the generated set threshold value is the P The threshold value 204 for the P seat associated with the seat is generated and stored (S25).

  Steps 20 to 25 are the operations for generating the D seat threshold 203 and the P seat threshold 204. Subsequently, detection of an operation using the D seat threshold value 203 and the P seat threshold value 204 will be described below.

The control unit 20 determines based on the sensor signal S ₆ and the load threshold 202 of the acceleration sensor 14 acquired, to a touch operation surface 100 of the operating finger, that is, the presence or absence of operation.
