Description

  The present invention relates to a multi-function rotation input device capable of inputting a plurality of target values for a control object, and more particularly to a multi-function rotation input device in which an operation range of a rotation operation member is variable according to the control object.

  For example, an input device applied to a car navigation system, a car air conditioner system, and the like includes a rotary input device having a rotation operation member that is rotated around one axis. The operator can select a target value to be controlled by rotating the rotary operation member. Some rotary input devices have a click mechanism that gives a click feeling to the operator when the rotary operation member is rotated.

  The simplest click mechanism can be constituted by a rotating member having a ball, a spring, and irregular portions provided periodically. The rotating member is provided so as to be rotatable integrally with the rotating operation member, for example, and the ball abuts against the uneven portion of the rotating member while being urged. In this click mechanism, a mechanical click feeling is given to the rotation operation member by the ball getting over the uneven portion as the rotation member rotates.

As an example that employs another click mechanism, in the haptic multifunctional rotation input device disclosed in Patent Document 1, the control unit clicks on the rotation operation member by switching the rotation direction of the motor at a predetermined angular position. A feeling is given.
Further, in this force-sensing multi-function rotary input device, when the rotary operation member continues to be operated beyond the limit point of the operation range, the maximum motor torque is finally rotated in the reverse direction. It is given to the member. Thus, the user can know by blind touch that the operation range has been exceeded.

  In addition, according to this force sense imparting type multifunctional rotation input device, the operation range of the rotary operation member can be arbitrarily set, and when there are a plurality of control objects, the operation range can be changed for each control object. .

JP 2006-11722 A

  In the force-giving type multi-function rotation input device disclosed in Patent Document 1, a click feeling is given by switching the rotation direction of the motor. The click feeling by the motor is a click of a simple click mechanism using a ball and a spring. Slightly different from the feeling. For this reason, some users may prefer the latter feeling of clicking.

Further, in the haptic multi-function rotation input device disclosed in Patent Document 1, although the rotation operation member is restricted from rotating beyond the limit point by the reverse torque of the motor, the rotation operation member is stopped. It may not be possible to For example, when the rotational operation member is vigorously rotated, the rotational operation member may rotate far beyond the limit point against the torque of the motor.
Thus, since the operator may feel uncomfortable that the rotation operation member rotates greatly outside the operation range exceeding the limit point, it is desired to be suppressed.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a multi-function rotation input device in which rotation of a rotary operation member outside an operation range is accurately suppressed while having a mechanical click feeling. It is to provide.

  In order to solve the above problems, the present invention employs the following solutions.

  Solution 1: According to one aspect of the present invention, a control target selection unit for selecting one of a plurality of control variables as a control target, and an operation performed by an operator to set the control target. A rotation operation member, a concavo-convex member having a plurality of projections and depressions arranged cyclically around the rotation axis of the rotation operation member, and a relative rotation with the concavo-convex member as the rotation operation member rotates. A frictional member that elastically contacts the unevenness of the uneven member, a rotation angle detecting means that outputs a detection signal corresponding to the rotation angle of the rotation operation member, and a frictional force applied to the rotating rotation operation member Possible friction brake means and control for calculating a detection rotation angle corresponding to the rotation angle of the rotation operation member based on the detection signal and performing drive control of the friction brake means based on the detection rotation angle The control means sets an operation range corresponding to the control object and a braking range adjacent to the operation range in a rotatable range of the rotary operation member, and the detected rotation angle within the braking range. When the operator operates the rotational operation member so that the distance changes in a direction away from the operation range, the friction brake means is driven and controlled to apply the frictional force to the rotational operation member. A multi-function rotary input device is provided.

  According to the multi-function rotation input device of the first solving means, when the rotation angle of the rotation operation member is within the operation range, the elastic contact member abuts against the unevenness while rotating relative to the rotation operation member. By bringing the elastic contact member into contact with the unevenness, a sharp mechanical click feeling can be reliably given to the rotary operation member with a simple configuration.

  On the other hand, in this multifunction rotation input device, the control means sets the operation range and the braking range, so that the position and width of the operation range are appropriately set according to the control target. For this reason, according to this multi-function rotation input device, the operator can easily input a command.

  In addition, in this multi-function rotation input device, a braking force sufficient to stop the rotation of the rotary operation member is applied by the friction brake means in the braking range. Therefore, in this multi-function rotation input device, undesired rotation of the rotation operation member within the braking range is reliably prevented, and the operator can remove the rotation operation member without feeling uncomfortable due to idling of the rotation operation member. It can be operated comfortably.

  Solving means 2: Preferably, when the detected rotation angle changes or stops in the direction toward the operation range within the braking range, the control unit is configured to detect a boundary between the operation range and the braking range, and The detected rotation angle or the position of the boundary is corrected so that the detected angle is relatively close.

  In the multi-function rotation input device of the second solving means, the detection rotation angle or the boundary position is corrected so that the position of the boundary between the operation range and the braking range is relatively close to the detection rotation angle. According to this correction, the operation range and the braking range are substantially reset with respect to the rotation angle of the rotary operation member. Before the reset, the rotation angle of the operation member is within the braking range within the operation range and the braking range. Even after the resetting, the rotation angle of the operating member is quickly returned to the operating range. Therefore, the operator can operate the rotary operation member in a timely and comfortable manner with little force required to return the rotation angle of the operation member to the operation range.

  Solution 3: Preferably, the control unit corrects the detected rotation angle or the position of the boundary in units of an angle corresponding to a cycle of the cam crest.

  According to the multi-function rotation input device of the third solving means, before and after resetting the operation range and the braking range, the correspondence relationship between the boundary between the operation range and the braking range and the cam mountain cycle does not change. For this reason, for example, when the boundary is matched with the valley between the cam mountains before resetting, the boundary matches with the valley between the cam peaks after resetting, and matches the boundary regardless of before and after resetting. When the rotation angle of the operating member is changed beyond the valley, a frictional force is applied to the operating member.

  Solution 4: Preferably, the position of the boundary between the operation range and the braking range coincides with a valley between the cam peaks.

  According to the multi-function rotation input device of the fourth solving means, the boundary between the operation range and the braking range matches the valley between the cam peaks, so it matches the boundary regardless of before and after resetting When the rotation angle of the operation member is changed beyond the valley, a frictional force is applied to the operation member. For this reason, according to this multi-function rotation input device, when the operation member is rotated to the boundary of the operation range, a click feeling is obtained, but further rotation of the operation member is prevented, and the operator can perform a good operation. A feeling is given.

  Solution 5: Preferably, the control means does not temporarily apply the friction force to the rotary operation member after the detected rotation angle changes or stops in a direction toward the operation range within the braking range. The friction brake means is driven as described above.

  According to the multi-function rotation input device of the fifth solving means, the control means allows the rotation operation member to rotate in the direction toward the boundary between the operation range to be reset and the braking range. By rotating the member, the rotation angle of the operation member is easily positioned at the boundary of the operation range. In particular, if the operation member is rotated by the elastic force of the elastic contact member, the rotation angle of the operation member can be automatically adjusted to the boundary between the operation range and the braking range.

  Solving means 6: Preferably, the rotation angle detecting means outputs a first magnetic sensor and a second magnetic sensor that output detection signals of sine waves having different phases in cooperation with the magnet as the rotating operation member rotates. The integer multiple of the period of the sine wave corresponds to an integral multiple of the period of the cam crest.

According to the multifunction rotation input device of the sixth solving means, the rotation angle of the rotation operation member is detected as the detected rotation angle based on the detection signals of the two sine waves. In this case, the relative positional relationship between the detected rotation angle and the unevenness of the uneven member can be known, and the friction brake means can be driven according to the unevenness of the uneven member. For example, when the unevenness is constituted by cam peaks, the boundary between the operation range and the braking range can be matched with the valleys between the cam peaks.
In this case, even if the rotation operation member rotates in the same direction many times, the rotation angle of the rotation operation member is detected as the detection rotation angle. For this reason, the settable range of the operation range and the braking range is wide, and even if the user continues to rotate the rotation operation member in one direction, a frictional force is accurately given to the rotation operation member.

  Solution 7: Preferably, the rotation angle calculation means calculates a phase angle corresponding to the rotation angle of the rotation operation member within one cycle of the sine wave based on a detection signal output from the rotation angle detection means. When the rotation angle of the rotation operation member changes beyond one cycle of the sine wave, the number of the cycle of the sine wave to which the rotation angle of the rotation operation member belongs is added or subtracted. A detection rotation angle calculation unit that calculates the detection rotation angle based on the phase angle and the cycle number of the sine wave.

  According to the multifunction rotation input device of the seventh solving means, the detected rotation angle is calculated with high accuracy by adding and subtracting the cycle number of the sine wave.

  Solving means 8: Preferably, the detected rotation angle calculation unit is a first value obtained by multiplying the rotation angle amount of the rotation operation member corresponding to one cycle of the sine wave by the cycle number of the sine wave. The detected rotation angle is calculated by adding a second value that is the rotation angle amount of the rotation operation member corresponding to the phase angle.

  According to the multifunction rotation input device of the eighth solving means, the detected rotation angle is calculated with high accuracy by adding the first value and the second value.

  ADVANTAGE OF THE INVENTION According to this invention, the multi-function rotation input device which has a mechanical click feeling and can suppress rotation of the rotation operation member outside an operation range exactly is provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic cross-sectional view showing an overall configuration of a multifunction rotary input device 10 according to an embodiment. The multifunction rotary input device 10 is used, for example, as an input device of a car air conditioner system, and is installed on an instrument panel or a center console in a vehicle cabin.

(Rotation operation member)
The multifunction rotary input device 10 includes, for example, a box-shaped or cylindrical housing 12, and has, for example, a columnar operation knob 14 as a rotation operation member outside the housing 12. The operation knob 14 is fixed to the tip end of the rotary shaft 16 rotatably supported by the housing 12 so as to be integrally rotatable. A person who intends to operate the car air conditioner system can change various settings of the car air conditioner system by rotating the operation knob 14 about the axis of the rotating shaft 16.

In this embodiment, as a preferable aspect, the rotating shaft 16 includes a drive shaft portion 18, a driven shaft portion 20, and a connecting portion 22 that elastically connects the drive shaft portion 18 and the driven shaft portion 20. An operation knob 14 is fixed to the tip of 18.
The connecting portion 22 is made of, for example, rubber, and when the operation knob 14 is rotated, when the driven shaft portion 20 is in a free state, the drive shaft portion 18 and the driven shaft portion 20 rotate substantially integrally with the driven shaft portion 20. When the load is applied, the connecting portion 22 is twisted, so that the rotation of the drive shaft portion 18 precedes the rotation of the driven shaft portion 20.

  When the operator releases the operation knob 14, the twist of the connecting portion 22 is eliminated, and the rotation angle of the drive shaft portion 18 matches the rotation angle of the driven shaft portion 20. Therefore, in the present embodiment, the rotation angles of the operation knob 14 and the rotation shaft 16 refer to the rotation angle θ of the driven shaft portion 20 unless otherwise specified.

[Mechanical click mechanism]
A substantially disk-shaped cam member 24 is coaxially and integrally attached to the driven shaft portion 20 of the rotating shaft 16. A plurality of cam ridges 26 are continuously formed in the circumferential direction on the outer peripheral surface of the cam member 24, and the cam ridges 26 form periodic irregularities on the outer peripheral surface of the cam member 24. In the present embodiment, the central angle of one cam peak 26 is 15 °, and a total of 24 cam peaks 26 are formed on the outer peripheral surface of the cam member 24.

On the other hand, for example, a cylindrical holder 28 is fixed to the housing 12. The holder 28 slidably supports, for example, an elastic contact member 30 having a hemispherical head, and a compression coil spring 32 as an urging means for urging the head of the elastic contact member 30 toward the cam crest 26. Is housed.
When the cam member 24 rotates with the rotation of the driven shaft portion 20, the elastic contact member 30 rotates relative to the cam member 24 while elastically contacting the cam crest 26. At this time, every time the elastic contact member 30 climbs over one cam crest 26, a clicking feeling is provided.

[Friction brake means]
The driven shaft portion 20 of the rotating shaft 16 penetrates the substantially cylindrical solenoid unit 34 so as to be relatively rotatable. The solenoid unit 34 has a double cylindrical core 36 made of a magnetic material such as iron. Inside the core 36, a solenoid (cylindrical coil) 38 made of a wire wound in a tubular shape is coaxial. Contained.
The core 36 is non-rotatably supported by the housing 12 via the bracket 40, and a resin-made sliding bearing 42 is installed between the outer peripheral surface of the driven shaft portion 20 and the inner peripheral surface of the core 36, for example. . Accordingly, the driven shaft portion 20 is supported by the core 36 and the housing 12 through the plain bearing 42 so as to be relatively rotatable.

  One end face of the core 36 faces the armature rotor 44. The armature rotor 44 is made of a magnetic material such as iron and has a disk-shaped main body 46. A central hole 48 is formed at the center of the main body 46, and the driven shaft portion 20 penetrates the central hole 48 with play. A slide bearing that allows the armature rotor 44 to move along the driven shaft portion 20 may be provided between the outer peripheral surface of the driven shaft portion 20 and the inner peripheral surface of the central hole 48.

The armature rotor 44 can be rotated integrally with the driven shaft portion 20 and can be moved in the axial direction of the driven shaft portion 20, and the main body portion 46 can come into contact with one end surface of the core 36. is there.
For this purpose, the armature rotor 44 has, for example, two rod portions 49. The rod portions 49 protrude in the axial direction from the surface of the main body portion 46 opposite to the core 36, and are separated from each other in the diameter direction of the main body portion 46. A disc-shaped support disk 50 is disposed on the opposite side of the main body 46 from the core 36, and the rod portion 49 is slidably inserted into an insertion hole 52 formed in the support disk 50.

  The support disk 50 is attached to the driven shaft portion 20 so as to be rotatable coaxially and integrally, and the armature rotor 44 can be rotated integrally with the driven shaft portion 20 via the support disk 50. The distance between the support disk 50 and the core 36 is set so that the armature rotor 44 can move in the axial direction of the driven shaft portion 20. Therefore, when the rod portion 49 slides in the insertion hole 52, the armature rotor 44 can move in the axial direction of the driven shaft portion 20 and can contact the end surface of the core 36.

  When a current is passed through the solenoid 38, the solenoid 38 generates a magnetic force, and the armature rotor 44 is attracted to the end face of the core 36 and comes into contact with a contact pressure corresponding to the magnetic force. When the driven shaft portion 20 rotates while the armature rotor 44 is in contact with the core 36, a frictional force corresponding to the contact pressure acts on the armature rotor 44 and the driven shaft portion 20 as a braking force.

[Detection of rotation angle of rotation shaft (rotation angle of driven shaft)]
Further, a disk-shaped magnet 54 is coaxially and integrally attached to the driven shaft portion 18. Two Hall sensors 56 a and 56 b are arranged in the vicinity of the outer peripheral portion of the magnet 54. Since the hall sensors 56a and 56b are separated from each other in the circumferential direction of the magnet 54, only the hall sensor 56a is shown in FIG.
FIG. 2 is a diagram for explaining the relative positional relationship among the magnet 54, the hall sensors 56a and 56b, and the mechanical click mechanism together with the structure of the magnet 54. FIG. Hereinafter, the hall sensor 56a is referred to as a first hall sensor 56a, and the hall sensor 56b is referred to as a second hall sensor 56b.

As shown in FIG. 2, the magnet 54 includes a plurality of N poles 58 and S poles 60 each having a fan shape, and the N poles 58 and the S poles 60 are alternately arranged in the circumferential direction. The center angles of the N pole 58 and the S pole 60 are each 15 ° and coincide with the center angle of the cam mountain 26.
Then, when viewed in the circumferential direction of the magnet 54, the apex of the cam peak 26 is located at the center of each of the N pole 58 and the S pole 60, and the trough 62 between the cam peaks 26 has an N pole 58 and an S pole 60. It is located at the boundary.

On the other hand, the first hall sensor 56 a and the second hall sensor 56 b are separated from each other at an angle of 7.5 ° in the circumferential direction of the magnet 54. Accordingly, the first Hall sensor 56a and the second Hall sensor 56b are equivalent to a quarter cycle when 30 °, which is the sum of the central angles of the pair of N poles 58 and S poles 60, is one cycle. It is separated as much as you want.
The first hall sensor 56a and the second hall sensor 56b detect a change in the magnetic field as the driven shaft portion 20 and the magnet 54 rotate, and output sine wave voltages whose phases are different from each other by 90 ° as detection signals. To do.

Here, in the present embodiment, as a preferable aspect, the central angles of the N pole 58 and the S pole 60 in the magnet 54, and the integer multiple of the period of the sine wave correspond to the integral multiple of the period of the cam crest 26, and The center angle of the cam mountain 26 is set.
In this specification, the expression sine wave is not used to distinguish between a sine wave and a cosine wave, but is used to mean that it periodically changes like a sine wave or a cosine wave. ing. Further, the integer multiple includes 1 time.

[Detection of rotation state of rotation shaft (micro rotation of drive shaft)]
Referring to FIG. 1 again, in the present embodiment, as a preferred mode, a means for detecting a minute rotation of the drive shaft portion 18 is provided as a means for detecting the rotation state of the rotary shaft 16.
Specifically, a code plate 64 as a detection object is coaxially and integrally attached to the drive shaft 18. The code plate 64 has a thin disk-shaped outer shape, and a plurality of slits extending in the radial direction are formed on the outer periphery of the code plate 64 at a constant interval in the circumferential direction, though not shown.

Two photo interrupter detectors 66 are arranged in the vicinity of the outer periphery of the code plate 64 so as to be separated from each other in the circumferential direction of the code plate 64. In FIG. 1, only one photo interrupter detector 66 is shown.
Each photo interrupter detector 66 has a pair of light emitting element 68 and light receiving element 70, and the light emitting element 68 and light receiving element 70 are arranged so as to sandwich the outer periphery of the code plate 64 in the thickness direction. .

Each light receiving element 70 intermittently receives the light emitted from the light emitting element 68 through the slit as the code plate 64 rotates, and outputs a rotation angle signal (encoder pulse) corresponding to the intensity of the received light. At this time, the two photo interrupter detectors 66 are separated from each other so that a phase difference is generated between the rotation angle signals output from the two light receiving elements 70.
Instead of the two photo interrupter detectors 66, a pulse encoder having the same function can be used.

(Control part)
The multifunction rotary input device 10 includes a control unit 72 configured using, for example, an MCU (microcomputer unit). The control unit 72 includes a solenoid 38, hall sensors 56a and 56b, and a photo interrupter detector 66. Are electrically connected.
FIG. 3 is a block diagram showing the electrical configuration of the multifunction rotary input device 10 together with the functional configuration of the control unit 72. As shown in FIG. 3, the control unit 72 includes a rotation angle calculation unit 74 that calculates the rotation angle θ of the driven shaft unit 20 as a detection rotation angle θc based on detection signals from the hall sensors 56a and 56b, and a photo interrupter. A micro-rotation calculation unit 76 that calculates the rotation angle θz of the drive shaft unit 18 based on the rotation angle signals of the detectors 66 and 66.

And the control part 72 has the friction brake drive control part 78 which controls the electric power supply with respect to the solenoid 38 based on detected rotation angle (theta) c.
In addition, the multi-function rotation input device 10 includes an outlet selection switch 80, an air volume selection switch provided outside the housing 12 as control target selection means for selecting one control target from among a plurality of control amounts. 82 and a temperature selection switch 84. The control unit 72 is electrically connected to the air outlet selection switch 80, the air volume selection switch 82, and the temperature selection switch 84, and is also electrically connected to the main controller 86 of the car air conditioner system.

  Note that the air outlet selection switch 80, the air volume selection switch 82, and the temperature selection switch 84 can be disposed in the vicinity of the housing 12. Further, the air outlet selection switch 80, the air volume selection switch 82, and the temperature selection switch 84 may be connected to the control unit 72 via the main controller 86. That is, the configuration of the control target selection unit is not particularly limited, and information related to the control target selected by the operator may be input to the control unit 72.

[Rotation angle calculator]
FIG. 4 is a graph for explaining a calculation method of the detected rotation angle θc executed by the rotation angle calculation unit 74.
The upper part of FIG. 4 shows the relationship between the detected rotation angle θ and the height of the cam peak 26, and the origin of the detected rotation angle θc coincides with the valley 62 between the cam peaks 26 in this embodiment. Yes.

  The middle part of FIG. 4 shows how the output voltage V1 of the detection signal of the first Hall sensor 56a and the output voltage V2 of the detection signal of the second Hall sensor 56b change according to the detection rotation angle θc.

  4, the output voltage V1 is represented by a cosine function that vibrates once every detection rotation angle θc changes by 30 °, that is, a cosine wave. The output voltage V2 has a detection rotation angle θc of It is represented by a sine function that vibrates once every 30 ° change, that is, a sine wave. The phase difference between the cosine wave and the sine wave is 90 °.

  The lower part of FIG. 4 is a graph showing the relationship between the detected rotation angle θc and the phase angle θe of the output voltages V1, V2. The phase angle θe of the output voltages V1 and V2 is obtained based on the arc tangent (arctan (V2 / V1)) having a value obtained by dividing the output V2 by the output V1 and the sign of the output signals V1 and V2.

As shown in FIG. 4, the phase angle θe indicates a sawtooth shape that vibrates once every time the detected rotation angle θc changes by 30 °. When a waveform number (period number N) is sequentially added to one vibration (period), the detected rotation angle θc can be calculated by the following expression (1).
θc = 30 × N + 30 × θe / 360 (1)

  Therefore, as shown in FIG. 5, the rotation angle calculation unit 74 includes a phase angle calculation unit 90 that calculates the phase angle θe based on the output voltages V1 and V2 of the detection signals when viewed in terms of function. The rotation angle calculation unit 74 calculates a cycle number N based on the phase angle θe calculated by the phase angle calculation unit 90, and calculates a detection angle θc based on the phase angle θe and the cycle number N. 92.

Specifically, the detected rotation angle calculation unit 92 increases or decreases the cycle number N one by one when the change amount Δθe of the phase angle θe exceeds a predetermined threshold value. As the threshold, for example, 180 ° and −180 ° are set, and when the change amount exceeds −180 ° and becomes smaller (Δθe <−180 °), the cycle number N is incremented by 1 (N = N + 1), When the change amount Δθe increases beyond 180 ° (Δθ> 180 °), the cycle number N is reduced by one.
That is, after setting the initial value once, the detected rotation angle calculation unit 92 increases or decreases the cycle number N by using the discontinuity of the phase angle θe at both ends of the sawtooth in principle. Note that the threshold is appropriately set according to the detection signal reading interval and the like.

[Selection of control target, setting of operation range / braking range, and friction brake]
On the other hand, the control unit 72 sets a part of the rotation angle range in which the operation knob 14 can be rotated as the operation range according to the control target selected by the person who operates the car air conditioner system, and is adjacent to the operation range. Set the braking range to the area to be used.

  Selection of the control target is performed by the air outlet selection switch 80, the air volume selection switch 82, and the temperature selection switch 84, and the operator can select the control target by pressing a desired selection switch.

The operation range set by the control unit 72 is a range for selecting a target value to be controlled. For example, when the control target is the air volume and the target value of the air volume can be set in five stages, as shown in FIG. 6, the operation range of the air volume includes four cam peaks 26.
In FIG. 6, the number of the cam crest 26 is based on the origin of the detected rotation angle θc, and the second, third, fourth and fifth cam crests 26 are included in the air volume operation range. The air volume operation range is set as a range of 15 ° or more and 75 ° or less when viewed with respect to the detected rotation angle θc.

  The area adjacent to the air volume operation range is set as a braking range, and the No. 6 to No. 24 and the No. 1 cam crest 26 are included in the braking range. Further, the braking range is set as a range of more than 75 ° to 360 ° and 0 ° to less than 15 ° when viewed with respect to the detected rotation angle θc.

FIG. 6 shows the urging force of the mechanical click mechanism and the friction force of the friction brake means in the operation range and the braking range. In the operation range, the friction brake means does not apply a friction force, and a click feeling by the mechanical click mechanism is obtained.
That is, in a state where the friction brake means is not functioning, the torque for rotating the driven shaft portion 20 changes according to the rotation angle θc by the elastic force (biasing force) of the compression coil spring 32 of the mechanical click mechanism. . In the present embodiment, as the driven shaft portion 20 rotates, the torque periodically increases and decreases every 15 ° that is the cycle of the cam crest 26.

On the other hand, the torque in the braking range is larger than the operating range. The increase in torque in the braking range is due to the frictional force applied to the armature rotor 44 by the friction brake means.
Specifically, the control unit 72 stops power supply to the solenoid 38 in the operation range, while supplying power to the solenoid 38 in the braking range, and causes the armature rotor 44 to be attracted to the core 34 by magnetic force.

When the armature rotor 44 tries to rotate while adsorbed to the core 34, a frictional force is applied to the armature rotor 44. Since the armature rotor 44 can rotate integrally with the driven shaft portion 20, the frictional force is transmitted to the driven shaft portion 20 and the operation knob 14 and acts as a braking force.
However, the frictional force in the braking range in FIG. 6 is generated when the operation knob 14 is rotated in a direction away from the operation range.

FIG. 7 shows the relationship among the temperature operation range, the braking range, the cam peak height, the cam peak number, the detected rotation angle θc, the urging force of the mechanical click mechanism, and the frictional force when the controlled object is temperature. Show. The temperature operation range includes seven cam peaks 26 of No. 2 to No. 8, and corresponds to a range of 15 ° to 120 ° of the detected rotation angle θc.
According to this temperature operation range, the target temperature value can be set in eight stages. Since the temperature operation range is wider than the air volume operation range, the boundary between the temperature operation range and the braking range is different from the boundary between the air volume operation range and the braking range. 7 is also generated when the operation knob 14 is rotated in a direction away from the operation range.

[Reset operation range and braking range]
In addition, in the present embodiment, as a preferable aspect, the control unit 72 can cancel the setting of the operation range and the braking range once according to the rotation of the operation knob 14 and newly set the operation range and the braking range again. is there.
For example, as shown in FIG. 8, the operation knob 14 is rotated in the direction away from the operation range (right rotation) beyond the boundary between the operation range and the braking range, and the detected rotation angle θc is 95 °. Consider a case. The detected rotation angle θc at this time is indicated by a black circle.

Thereafter, when the operation knob 14 stops or is rotated in the direction in which the operation knob 14 approaches the operation range (left rotation), the control unit 72 sets the detected rotation angle θc as shown in FIG. A corrected rotation angle θr corrected by the correction amount θa is calculated.
The operation range and the braking range are set based on the corrected detection angle θc, that is, the corrected rotation angle θr. Therefore, correcting the detected rotation angle θc is equivalent to changing the position of the operation range and the braking range in terms of the number of the cam crest 26 or the absolute angle, and resetting the operation range and the braking range. be equivalent to. Then, the detected rotation angle θc is corrected so that the correction rotation angle θr approaches the boundary between the operation range and the braking range.

In the present embodiment, as a preferred mode, the detected rotation angle θc is corrected in units of 15 ° corresponding to one cycle of the cam crest 26. In FIG. 8, the correction amount θa is −15 °. Specifically, the correction amount θa is calculated using either of the following formulas (2) and (3).
θa = −round {(θc−θR) / 15} (2)
θa = round {(θL−θc) / 15} (3)

Here, in Expressions (2) and (3), round is a function that rounds off the first decimal place and makes the variable (θc−θR) / 15 or (θL−θc) / 15 an integer. In FIG. 6, θR is a detected rotation angle θc corresponding to the boundary between the air volume operation range and the right control range when the correction amount θa = 0, and is 75 °. As seen in FIG. 6, θL is a detected rotation angle θc corresponding to the boundary between the air volume operation range and the left control range when the correction amount θa = 0, and is 15 °.
When the detected rotation angle θc is within the right braking range, the correction amount θa is calculated using Equation (2), and when it is within the left braking range, the correction amount θa is calculated using Equation (3). The

  In addition, in the present embodiment, as a preferred mode, when the operation knob 14 stops or is rotated in a direction approaching the operation range, the braking force by the friction brake means is temporarily released. That is, the operation range and the braking range are substantially canceled. As a result, the driven shaft portion 20 is rotated by the elastic force of the compression coil spring 38 of the mechanical click mechanism, and the rotation angle θ of the operation knob 14 is automatically set as indicated by a white circle in FIG. Is made to coincide with the valley 62 between the cam peaks 26.

  Then, when a predetermined time elapses, the control unit 72 operates the friction brake means as necessary, and as shown in FIG. 10, the operation range and the braking range are set according to the correction rotation angle θr. The operation knob 14 can be operated. Note that the frictional force in the braking range in FIG. 10 is also the torque when the operation knob 14 is rotated in a direction away from the operation range.

The rotation state of the operation knob 14, that is, determination of right rotation, left rotation, or stop can be performed based on the amount of change in the detected rotation angle θc. In this embodiment, the rotation angle signal of the photo interrupter detector 66 is used. By performing based on the above, a minute rotation can be determined quickly and accurately.
In particular, when the operation knob 14 is rotated in a direction away from the operation range in a state in which a frictional force is applied to the armature rotor 44, the connecting portion 22 is twisted, and then the operator releases the hand from the operation knob 14. The twist of the connecting portion 22 is eliminated. As the twist of the connecting portion 22 is eliminated, the operation knob 14 and the drive shaft portion 18 rotate in the opposite direction. By detecting the rotation in the reverse direction with the photo interrupter detector 66, it is possible to quickly and accurately detect that the operator has stopped operating the operation knob 14.

[Control processing procedure]
FIG. 11 is a flowchart illustrating an example of a procedure of control processing executed by the processor of the control unit 72 when the operator presses the air volume selection switch 82. Note that the procedure of the control process is stored as a program in the memory of the control unit 72.

Step S10: First, the processor reads the air volume operation setting information as an initial setting process. The setting information of the air flow operation is information for setting the operation range and the braking range related to the air flow operation, and the detected rotation angle θc when the air flow selection switch 82 is pressed in addition to the width of the operation range and the braking range. The positional relationship with the operation range is also included.
Step S12: As an initial setting process, the processor initializes the cycle number N and the correction amount θa and sets them to zero.
Step S14: Then, the processor reads the output voltages V1 and V2 of the detection signals of the first hall sensor 56a and the second hall sensor 56b.

Step S16: The processor calculates the phase angle θe based on the read output voltages V1 and V2.
Step S18: The processor calculates the detected rotation angle θc by substituting the calculated phase angle θe into the above-described equation (1).

Step S20: Then, the processor stores the phase angle θe calculated in step S16 in the memory as the old phase angle old θe.
Step S22: The processor sets the operation range and the braking range based on the air volume setting information read in step S10 and the detected rotation angle θc calculated in step S18.

Step S24: Thereafter, the processor again reads the output voltages V1 and V2 of the detection signals of the first Hall sensor 56a and the second Hall sensor 56b.
Step S26: The processor calculates the phase angle θe based on the output voltages V1 and V2 read in step S24.

Step S28: The processor then executes a rotation angle calculation routine to calculate the detected rotation angle θc.
Step S30: Thereafter, the processor stores the phase angle θe calculated in step S26 in the memory as the old phase angle old θe.
Step S32: The processor outputs the detected rotation angle θc calculated in step S28 or the target value to be controlled corresponding to the detected rotation angle θc to the main controller 86 of the car air conditioner system.

Step S34: Further, the processor executes a friction brake drive control / braking range reset routine to apply a frictional force according to the detected rotation angle θc, and to reset the operation range and the braking range as necessary. The correction amount θa is calculated.
Step S36: Thereafter, the processor confirms whether or not the air volume selection switch 82 is still on. If it is on, the processor returns to step S24, and if it is off, ends the program.
Note that the loop of step S24 to step S36 is repeatedly executed, for example, at intervals of 0.1 ms.

[Rotation angle calculation routine]
FIG. 12 is a flowchart showing a procedure example of control processing executed by the processor in the rotation angle calculation routine (step S28) in FIG.
Step S38: First, the processor calculates the change amount Δθe of the phase angle θe by dividing the previous phase angle oldθe calculated by the previous phase angle θe calculated in the immediately preceding step S26.

Step S40: Then, the processor determines whether or not the change amount Δθe is larger than a threshold value of 180 °.
Step S42: If the change amount Δθe is greater than 180 ° as a result of the determination in step S40, the processor subtracts 1 from the cycle number N.
Step S44: Then, the detected rotation angle θc is calculated by substituting the cycle number N and the phase angle θe subtracted in step S42 into the equation (1).
Step S45: The correction rotation angle θr is calculated by adding the correction amount θa to the detected rotation angle θc calculated in step S44.

Step S46: On the other hand, if the change amount Δθe is 180 ° or less as a result of the determination in step S40, the processor determines whether or not the change amount Δθe is smaller than another threshold value of −180 °. .
Step S48: If the change amount Δθe is smaller than −180 ° as a result of the determination in step S46, the processor adds 1 to the cycle number N. Then, the processor proceeds to step S44, and in this case, the detected rotation angle θc is calculated by substituting the cycle number N and the phase angle θe added in step S48 into the equation (1).
If the change amount Δθe is larger than −180 ° as a result of the determination in step S40, that is, if the change amount Δθe is −180 ° or more and 180 ° or less, the cycle number N is not changed and is detected as it is. Used to calculate the rotation angle θc.

[Friction brake drive control and braking range reset]
FIGS. 13 and 14 are flowcharts showing a procedure example of control processing executed by the processor in the friction brake drive control / braking range resetting routine (step S34) of FIG.
Step S50: The processor determines whether the corrected rotation angle θr calculated in the rotation angle calculation routine (step S28) is within the air volume operation range, the left braking range, or the right braking range. . The air volume operation range is 15 ° or more and 75 ° or less, the right braking range is more than 75 °, and the left braking range is set to less than 15 °.

Step S52: As a result of the determination in step S50, when the corrected rotation angle θr is within the right braking range, the processor determines whether or not the operation knob 14 is stopped or rotated to the left.
Note that the left rotation is a rotation toward the air flow operation range, and whether or not the operation knob 14 is stopped or rotated to the left may be determined from a change amount of the detected rotation angle θc or the correction rotation angle θr. The determination may be made based on the rotation angle detection signal of the photo interrupter detector 66.

Step S54: If the result of the determination in step S52 is that the operation knob 14 has stopped or rotated counterclockwise, the processor deactivates the friction brake (off) and causes the timer to start counting for a predetermined time.
Step S56: Then, the processor changes the correction amount θa and resets the operation range and the braking range. Specifically, the correction amount θa is changed based on the above-described equation (2).

Step S58: Thereafter, the processor waits until the timer finishes counting for a predetermined time. When the counting ends in step S58, the processor returns to step S36 in FIG.
Step S60: On the other hand, if the result of the determination in step S52 is that the operation knob 14 is not stopped or rotated counterclockwise and is further rotated clockwise, the processor activates (turns on) the friction brake. Then, the processor returns to step S36 in FIG.

Step S62: Also, if the result of the determination in Step S50 is the result of the determination in Step S52: Step S50 is that the corrected rotation angle θr is within the left braking range, the processor determines whether the operation knob 14 is stopped or rotated to the right. Determine whether or not.
The right rotation is a rotation toward the air volume operation range, and whether the operation knob 14 is stopped or rotated to the right may be determined from the amount of change in the detected rotation angle θc or the correction rotation angle θr. The determination may be made based on the rotation angle detection signal of the photo interrupter detector 66.

Step S64: If the result of the determination in step S62 is that the operation knob 14 is stopped or rotated to the right, the processor deactivates the friction brake (off) and causes the timer to start counting for a predetermined time.
Step S66: Then, the processor changes the correction amount θa and resets the operation range and the braking range. Specifically, the correction amount θa is changed based on the above-described equation (3).

Step S68: Thereafter, the processor waits until the timer finishes counting for a predetermined time. When the counting ends in step S68, the processor returns to step S36 in FIG.
Step S70: On the other hand, if the result of the determination in Step S62 is that the operation knob 14 is not stopped or rotated to the right and is further rotated to the left, the processor activates (turns on) the friction brake. Then, the processor returns to step S36 in FIG.

  Step S72: If the result of determination in step S50 is that the corrected rotation angle θr is within the operating range, the processor deactivates the friction brake (off) and then does not reset the braking range, as shown in FIG. The process returns to step S36.

  According to the multi-function rotation input device 10 of the above-described embodiment, when the rotation angle θ or the correction rotation angle θr of the operation knob 14 as the rotation operation member is within the operation range, the elastic knob 10 is rotated along with the rotation of the operation knob 14. The contact member 30 contacts the cam crest 26 while rotating relatively. By bringing the elastic contact member 30 into contact with the cam crest 26, a sharp mechanical click feeling is reliably given to the operation knob 14 with a simple configuration.

  On the other hand, in the multi-function rotation input device 10, the control unit 72 as control means sets the operation range and the braking range, so that the position and width of the operation range are appropriately set according to the control target. For this reason, according to this multifunctional rotation input device 10, the operator can input a command easily.

  Moreover, in this multi-function rotation input device 10, a braking force sufficient to stop the rotation of the operation knob 14 is applied by the friction brake means in the braking range. Therefore, in this multi-function rotation input device 10, undesired rotation of the operation knob 14 within the braking range is surely prevented, and the operator does not feel a sense of incongruity due to idling of the operation knob 14. Can be operated comfortably.

  In the multi-function rotation input device 10 according to the embodiment described above, the correction rotation is performed so that the detected rotation angle θc detected by the rotation angle calculation unit 74 approaches the position of the boundary between the operation range and the braking range. The angle θr is corrected. According to this correction, the operation range and the braking range are substantially reset with respect to the rotation angle θ of the operation knob 14, and before the resetting, the detected rotation angle θc is within the braking range within the operation range and the braking range. Even if it is located far from the boundary between and, the corrected rotation angle θr after resetting is quickly returned to the operation range. For this reason, the operator can operate the operation knob 14 in a timely and comfortable manner with little force required to return the rotation angle θ of the operation knob 14 to the operation range.

  Furthermore, according to the multi-function rotary input device 10 of the above-described embodiment, as is apparent from the equations (2) and (3), the correction amount θa is set in units of 15 ° that is the period of the cam crest 26. The calculated operation range and the braking range are reset using the correction amount θa. Thereby, before and after resetting the operation range and the braking range, the correspondence between the boundary between the operation range and the braking range and the cycle of the cam crest 26 does not change.

  Furthermore, according to the multifunction rotary input device 10 of the above-described embodiment, the boundary between the operation range and the braking range coincides with the valley 62 between the cam peaks 26. As a result, regardless of before and after the resetting, if the corrected rotation angle θr changes beyond the valley 62 that coincides with the boundary, a braking force based on the frictional force is applied to the operation knob 14. For this reason, according to this multi-function rotation input device 10, when the operation knob 14 is rotated to the boundary of the operation range, a click feeling can be obtained, but further rotation of the operation knob 14 is prevented, and the operator can be prevented. A good operational feeling is given.

  Further, according to the multi-function rotation input device 10 of the above-described embodiment, even if the rotation angle θ of the operation knob 14 is within the braking range, the friction brake is temporarily deactivated in step S54 or step S56. The Accordingly, since the control unit 72 allows the operation knob 14 to rotate in the direction toward the boundary between the operation range to be reset and the braking range, the correction rotation angle θr is rotated by rotating the operation knob 14. Is easily located at the boundary between the operating range and the braking range. In particular, if the operation knob 14 is rotated by the elastic force of the elastic contact member 30, the corrected rotation angle θr can be automatically adjusted to the boundary between the operation range and the braking range.

On the other hand, according to the multi-function rotation input device 10 of the above-described embodiment, based on the detection signals of two sine waves, the detection rotation angle θc of the operation knob 14 is determined using an arbitrary position as a reference for the detection rotation angle θc. Detected.
Here, the integer multiple of the period of the sine wave corresponds to an integral multiple of the period of the cam peak 26, and the relative positional relationship between the period of the sine wave and the period of the cam peak 26 is preset. Yes. For this reason, even if the detected rotation angle θc of the operation knob 14 is deviated from the valley 62 between the cam peaks 26 at the initial setting of Step S10 and Step S12, Step S22 is performed based on the detected rotation angle θc calculated in Step S18. By setting the operation range and the braking range, the boundary between the operation range and the braking range can be easily positioned at the valley 62 between the cam peaks 26, for example.
In this case, even if the operation knob 14 rotates many times in the same direction, the rotation angle θ of the operation knob 14 is detected as the detected rotation angle θc. For this reason, the setting range of the operation range and the braking range is wide, and even if the user continues to rotate the operation knob 14 in one direction, a frictional force is given to the operation knob 14 accurately.

  Further, according to the multi-function rotation input device 10 of the above-described embodiment, the two hall sensors 56a and 56b and the disk-shaped magnet 54 can detect two sine waves having different phases from each other with a simple configuration. A signal is obtained.

Furthermore, according to the multi-function rotary input device 10 of the above-described embodiment, a saw wave is obtained based on two sine wave detection signals having a phase difference of 90 °, and the operation knob 14 is detected based on the saw wave. By calculating the rotation angle θc, the detected rotation angle θc can be calculated with high accuracy with a simple configuration.
That is, according to the above-described equation (1), by counting the cycle number N, the 30 × N term does not include an error, and only the 30 × θe / 360 term includes an error. For this reason, errors do not accumulate as the detected rotation angle θc increases, and the detected rotation angle θc is calculated with high accuracy.

The present invention is not limited to the above-described embodiment, and includes a mode in which the above-described embodiment is appropriately modified.
For example, in the above-described embodiment, the rotating shaft 16 includes the connecting portion 22 that elastically connects the drive shaft portion 16 and the driven shaft portion 20, but the connecting portion 22 may be omitted. Further, the photo interrupter detector 66 for detecting the rotation angle of the drive shaft portion 16 may be omitted.

In the mechanical click mechanism of the embodiment described above, the cam crest 26 is provided on the outer peripheral surface of the cam member 24 that rotates integrally with the operation knob 14. The direction of the elastic contact member 30 may be changed so that the elastic contact member 30 is formed on the surface and abuts on the flat surface of the cam member 24 perpendicularly.
Further, the cam crest may be provided on the housing 12 side, and the elastic contact member 30 may be installed so as to rotate integrally with the operation knob 14. Further, the shape and number of the elastic contact members 30 are not particularly limited, and the urging means for urging the elastic contact members 30 is not limited to the compression coil spring 32.
Furthermore, the unevenness of the mechanical click mechanism does not need to be a smooth unevenness formed by the cam crest 26, and may be formed by bottomed holes or the like arranged periodically. Moreover, the period of unevenness is not particularly limited.

  In the above-described embodiment, the friction brake means applies the frictional force to the armature rotor 44 by attracting the armature rotor 44 to the core 34, but the armature rotor 44 is pressed against the support disk 50 by the magnetic force. The solenoid unit 34 may be configured. Furthermore, a shoe for sandwiching the support disk 50 in the radial direction may be provided, and the shoe may be pressed against the outer periphery of the support disk 50 by a solenoid unit.

Further, in the above-described embodiment, the hall sensors 56a and 56b are used as sensors for detecting the rotation angle θ of the operation knob 14, but MR (magnetic resistance) sensors may be used.
Furthermore, in the above-described embodiment, although the detection rotation angle θc is corrected so that the position of the boundary between the operation range and the braking range detection and the detection rotation angle θc are relatively close to each other, You may make it correct | amend the position of the boundary between braking ranges.

In addition, the shapes and arrangements of the various members shown in the drawings and the control processing are all preferable examples, and it goes without saying that these can be appropriately changed when implementing the present invention.
Finally, the present invention is suitable for an input device for a car air conditioner system, but is also suitable for other devices such as a car audio system and a car navigation system, and can also be applied to a personal computer or the like. Of course there is.
