Prior to this, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms, and the inventor should appropriately interpret the concepts of the terms appropriately It should be interpreted in accordance with the meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined. Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

1 is an exploded perspective view showing a configuration of a clutch control apparatus for a manual transmission vehicle according to a preferred embodiment of the present invention, and Fig. 2 is a plan view of Fig.

Referring to FIGS. 1 and 2, a clutch control apparatus for a manual transmission vehicle according to a preferred embodiment of the present invention includes a drive motor 110, a push-pull rod 120 installed to move forward and backward linearly, A link assembly 130 connected between the drive motor 110 and the push rod 120, a rotation angle sensor 140 arranged to contact one side of the link assembly 130, (See 150 in Fig. 6).

The push-pull rod 120, the link assembly 130, and the rotation angle sensor 140 are disposed in the inner space of the main body housing 100. The main body housing 100 is preferably sealed by the cover plate 102 with the gasket 101 interposed therebetween at the upper edge portion to prevent corrosion or failure of the driving parts and the sensor due to moisture or the like.

The driving motor 110 is mounted on the rear surface of the main body housing 100 as shown in FIG. 5 to provide a rotational force for driving the push-pull rod 120. As the driving motor 110, a DC motor capable of forward rotation and reverse rotation in accordance with a control signal is employed. With reference to the plan view of FIG. 2, the counterclockwise rotation of the drive motor 110 is defined as "forward rotation" and the clockwise rotation is defined as "reverse rotation" for the sake of understanding.

The push-pull rod 120 is installed in such a manner that it can be linearly moved back and forth between a position capable of transmitting power to the clutch and a position capable of interrupting the power, which is operatively connected to the clutch of the manual transmission vehicle, do. 2 and 3 show an example in which the first position A and the second position B are specified with respect to the rear end of the push-pull rod 120 for the convenience of understanding. During the normal rotation of the drive motor 110, the end portion of the push-pull rod 120 is pulled backward to move to the second position B as shown in Fig. 3, And moves to the first position A as shown in Fig.

In order to transmit the forward and backward movements of the push-pull rod 120 to the clutch or to the elements mechanically connected to the clutch, a push rod 120 is provided at the front end of the push- The wire member 121 can be connected. In addition, it is preferable that a tube member 103 having a predetermined length capable of receiving and protecting the push-pull rod 120 is provided on the inner surface of the main body housing 100.

The wire member 121 and the push-pull rod 120 may be attached to the inside of the tube member 103 to prevent the wire member 121 and the push-pull rod 120 from being abraded or damaged by friction. A spring member of a coil type arranged so as to penetrate through the hollow can be provided. Considering that the positions of the wire member 121 and the push-pull rod 120 are somewhat varied in the lateral direction during the forward and backward movement, the inner wall of the tube member 103 moves inward of the main housing 100 It is preferable to form the substantially conical shape so as to gradually increase the diameter.

The forward end of the push-pull rod 120 is pulled back and is moved to the second position B while the wire member 121 is pulled to pull the element connected to the clutch or clutch, It is possible to obtain the same operational effect as when the clutch pedal is depressed. On the contrary, when the drive motor 110 rotates in the reverse direction, the rear end of the push-pull rod 120 advances forward and moves to the first position A while at the same time the wire member 121 advances to connect the element connected to the clutch or clutch It is possible to obtain the same action and effect as when the clutch pedal is actually released from the clutch pedal.

The link assembly 130 is connected between the drive motor 110 and the push-pull rod 120 to convert the rotational motion of the drive motor 110 into linear motion of the push-pull rod 120. Each link of the link assembly 130 is formed of a metal bar having a predetermined thickness.

Specifically, the link assembly 130 includes a first link 131 having one end fixed to the rotation axis of the driving motor 110 and rotating integrally with the rotation axis, and a second link 131 having one end overlapped with the other end of the first link 131, A third link 133 which is hingedly coupled to the other end of the second link 132 by being overlapped with the other end of the second link 132 and a third link 133 which is connected to the third link 133, And a fourth link 134 coupled to the rear end of the second link 134. [

The first link 131 and the second link 132 switch the rotary motion of the driving motor 110 to the rotating motion of the third link 133. The length of the first link 131 is longer than the length of the second link 131 132). According to this configuration, the turning radius of the first link 131 can be reduced, and the volume of the apparatus can be reduced.

Since the third link 133 and the fourth link 134 are integrally formed, the fourth link 134 also rotates at the same time as the third link 133 rotates. A rotation center portion for rotating the fourth link 134 integrally with the third link 133 is provided at a portion where the third link 133 and the fourth link 134 are connected to each other. The angle between the third link 133 and the fourth link 134 is orthogonal to each other in consideration of the stroke length of the push-pull rod 120 for interrupting the clutch, The length of the fourth link 134 is preferably longer than the length of the third link 133.

As described above, the ends of the links forming the link assembly 130 are overlapped and hinged to each other. Accordingly, the fourth link 134 is spaced apart from the inner bottom surface of the main body housing 100 by a predetermined height. The fourth link 134 has a bar-shaped guide projection for stably guiding the movement of the fourth link 134 from the bottom. (Not shown) protrudes from the inner bottom surface of the main body housing 100. The guide protrusion preferably extends substantially in parallel with the linear movement direction of the push pull rod 120.

Preferably, the link assembly 130 is designed to support a linear reciprocating motion of one cycle with respect to the push-pull rod 120 during one revolution of the drive motor 110. Accordingly, when the driving motor 110 rotates 180 degrees, the link assembly 130 pulls the push-pull rod 120 backward, for example, by 1/2 cycle from the first position A to the second position B, . In this state, when the drive motor 110 rotates 180 degrees, the link assembly 130 pushes the push-pull rod 120 forward, and moves the link assembly 130 by 1/2 cycle from the second position B to the first position A .

The rotation angle sensor 140 is disposed at one side of the link assembly 130 to detect movement of the push-pull rod 120. Specifically, the rotation angle sensor 140 senses the movement position of the push-pull rod 120 while maintaining contact with the fourth link 134 directly connected to the push-pull rod 120. [ Since the linear movement position of the push-pull rod 120 is defined by the rotation angle of the fourth link 134, the movement of the push-pull rod 120 can be accurately detected by detecting the rotation angle of the fourth link 134 .

The rotation angle sensor 140 is a module that is modularized to sense a rotation angle of a measurement object and output a voltage value. The rotation angle sensor 140 includes a sensor body having a predetermined sensing element, A tilt bar 141 to which a predetermined spring (not shown) is coupled so as to be biased, and a roller unit 142 that is rollably installed at an end of the tilt bar 141.

The tilt bar 141 has an angle range between a first point a corresponding to the first position A of the push-pull rod 120 and a second point b corresponding to the second position B, And is rotatably mounted on the sensor body.

The roller portion 142 maintains constant contact with one side of the link assembly 130 due to the elastic bias of the tilt bar 141. That is, during operation of the link assembly 130, the roller portion 142 remains in contact with one side of the fourth link 134 of the link assembly 130. The fourth link 134 rotates about the rotation center and the roller 142 rotates in contact with the surface of the fourth link 134 so that the tilt bar 141 rotates about the first point a, And the second point (b).

The controller 150 receives the control signal according to the operation of the clutch operation button 17 provided on the gear lever 1 of the manual transmission vehicle and rotates the drive motor 110 forward / And controls the pulling or pushing operation. The clutch operation button 17 is provided in a predetermined additional device to be mounted on the gear lever 1, and can be preferably configured as a push button type.

The controller 150 recognizes the movement amount of the push pull rod 120 from the voltage output value of the rotation angle sensor 140 corresponding to the rotation angle of the tilt bar 141. [

6, the controller 150 is provided with a button such as a clutch operation button 17 and the like provided on the gear lever 1, an automobile battery power source 2, an RPM detection signal input unit 10, The brake switch 12, the speed sensor 13, the ignition switch 14, the accelerator sensor 15, the neutral sensor 16, the drive motor 110, the half-clutch position adjustment volume 160, And is electrically connected.

The controller 150 recognizes the half-clutch state from the voltage output value output from the rotation angle sensor 140 when the tilting bar 141 is located at the third point c. As shown in Fig. 4, the third point c corresponds to the half-clutch position H between the first position A and the second position B.

The half clutch position adjustment volume 160 is added to the clutch control device in consideration of the fact that the half clutch position H differs by vehicle type. The half-clutch position adjustment volume 160 is composed of a variable resistance element and adjusts the position of the half-clutch by matching the adjustment value of the half-clutch adjustment volume with the voltage output value outputted from the rotation angle sensor 140.

Hereinafter, the operation control of the clutch control apparatus for a manual transmission vehicle according to a preferred embodiment of the present invention will be described separately for each step of driving the vehicle.

Preparations for driving

When the driver pushes a predetermined clutch operation button 17 located on the gear lever 1 in order to insert a gear in the stopped state of the automobile, the controller 150 performs control to rotate the drive motor 110 forward.

The drive motor 110 rotates in the counterclockwise direction by a predetermined angle under the control of the controller 150 and is driven by the operation of the link assembly 130 interlocked with the drive motor 110 in the forward direction, Is pulled and the rear end reaches the second position B, a complete clutch cut-off state is obtained. In this state, the tilt bar 141 of the rotation angle sensor 140 is located at the second point b.

During operation of the link assembly 130, the rotation angle sensor 140 is configured to rotate the tilt bar 142 located at the second point b, while maintaining the roller 142 in continuous contact with the fourth link 134 of the link assembly 130. [ And outputs a voltage value corresponding to the rotation angle of the rotor 141. [ The controller 150 receives the voltage value and recognizes the movement position of the push-pull rod 120 corresponding to the rotation angle of the fourth link 134 and reflects the movement position to the stop control of the drive motor 110, 120) to the second position (B).

Start step

Thereafter, the controller 150 performs a control for automatically rotating the driving motor 110 in the clockwise direction by detecting a low signal generated as the brake of the vehicle is switched from the turn-on state to the turn-off state .

The operation of the link assembly 130 as the drive motor 110 is rotated counterclockwise by the predetermined angle of the half clutching position adjustment volume 160 causes the push pull rod 120 to move from the second position B to the half- The wire member 121 advances and is switched to the half-clutch state. In the half-clutch state, the tilt bar 141 of the rotation angle sensor 140 is located at the third point c. The half-clutch position H is determined by the half-clutch position adjustment volume 160 within the interval between the first position A and the second position B, considering that the half-clutch position H differs by vehicle type It is adjusted and set in advance.

The controller 150 receives the voltage value corresponding to the tilt angle of the tilt bar 141 located at the third point c and outputs the voltage value corresponding to the rotation angle of the fourth link 134 Clutch rod 120 is moved to the half-clutch position H by recognizing the movement position of the corresponding push-pull rod 120 and reflecting it to the stop control of the drive motor 110. [

Acceleration stage

The controller 150 automatically rotates the driving motor 110 to rotate the push-pull rod 120 in the half-clutch position (for example, (H) to the first position (A).

The push rod 120 is moved from the half-clutch position H to the first position A at a first speed by the operation of the link assembly 130 as the drive motor 110 is rotated counterclockwise by a predetermined angle And is switched to the clutch connection state. In the clutch connected state, the tilt bar 141 of the rotation angle sensor 140 is located at the first point a.

The controller 150 receives the voltage value corresponding to the tilt angle of the tilt bar 141 located at the first point a and determines the movement position of the push rod 120 corresponding to the tilt angle of the fourth link 134 And controls the movement of the push-pull rod 120 to the first position (A) by reflecting it to the stop control of the drive motor (110).

Thereafter, when the driver presses the clutch operation button 17 for shift of the gear while the vehicle is running at a predetermined RPM, the controller 150 performs control for forward rotation of the drive motor 110, 120 to the second position B to switch to the clutch disengaged state.

When the driver releases the depression of the clutch operation button 17 after the completion of the gear shifting, the controller 150 performs a control to reverse the drive motor 110 so that the push pull rod 120 is moved to the half- H) to the first position (A) at the second speed. At this time, the controller 150 controls the driving motor 110 such that the second speed is relatively faster than the first speed so that the power is quickly transmitted to the clutch.

Deceleration and stop phase

When the brake or the like is turned on according to the brake operation of the vehicle, the controller 150 monitors the RPM of the engine to recognize the running state. When the RPM of the engine gradually decreases to a predetermined value, the controller 150 automatically rotates the drive motor 110 to perform the control of pulling the push-pull rod 120 to the half-clutch position H.

The controller 150 rotates the drive motor 110 forward at the moment when the RPM is reduced to 800 RPM, for example, when the RPM gradually decreases so as to utilize the engine brake to the maximum, so that the rear end of the push- And performs pulling control to the position (B). After the position of the push-pull rod 120 is switched to the half-clutch position H, the start-off phenomenon does not occur even if the vehicle is stopped by completely stepping on the brake.

7 is a plan view showing a configuration of a clutch control apparatus for a manual transmission vehicle according to another embodiment of the present invention. In the drawings, the same reference numerals as in the above-described embodiments correspond to the same elements. In this embodiment, the rotational motion of the driving motor 110 is switched to reciprocating motion by the link assembly 130 'to move the wire member 121 forward and backward. To this end, the link assembly 130 'includes a first link 131', one end of which is connected to the rotation axis 111 of the drive motor 110 and rotates together with the rotation axis 111, The end portion of the wire member 121 drawn to the inside of the main body housing 100 is fixed to the end of the second link 132 'by bolts or the like, do. The wire member 121 moves forward and backward by the interaction of the first link 131 'and the second link 132' when the driving motor 110 rotates.

The wire member 121 is installed in the cable sheath 122 so as to be able to move forward and backward, and is operatively connected to the clutch of the manual transmission vehicle. The wire member 121 is provided so as to be movable forward and backward between a position capable of transmitting power to the clutch and a position capable of interrupting the power. 7 and 9 show an example in which the first position A 'and the second position B' are specified based on the rear end of the wire member 121 for the sake of understanding.

The link assembly 130 'is designed to support a linear reciprocating motion of one cycle with respect to the wire member 121 in one rotation of the drive motor 110. When the drive motor 110 rotates 180 degrees, the link assembly 130 'pulls the wire member 121 backward so that the link assembly 130' can cut the power from the first position A ' 2 position (B '). In this state, when the driving motor 110 rotates 180 degrees, the link assembly 130 'advances the wire member 121 forward to move the wire member 121 from the second position B' to the first position A ' Move it by two cycles.

When the driving motor 110 rotates, the first link 131 'rotates and the second link 132' rotates about the hinge axis relative to the first link 131 ' ) Substantially linearly moves forward and backward between the first position (A ') and the second position (B'). When the rear end of the wire member 121 is in a section between the first position A 'and the second position B' as shown in Fig. 8, the above-described half-clutch function can be implemented.

The wire member 121 can be pulled to a predetermined position to pull the element connected to the clutch or the clutch, thereby achieving the same operational effect as pressing the clutch pedal substantially when the driving motor 110 is rotated in one direction. On the contrary, when the drive motor 110 rotates in the opposite direction, the wire member 121 advances forward to push the element connected to the clutch or the clutch to the original position, thereby achieving substantially the same effect as pulling the foot off the clutch pedal .

The cam member 112 is eccentrically connected to the rotating shaft 111 of the driving motor 110 and rotates together with the rotating shaft 111 and the link assembly 130. At the edge of the cam member 111, 140 are in contact with each other.
