It shows the graph of the form.

In the shift operation detecting apparatus for a vehicle transmission according to the first exemplary embodiment of the present invention, the position of the control finger 200 is controlled in such a manner that the main sensing sensor 500 detects both the magnetic field polarity change and the magnetic field strength change of the main magnet 300. It is a device that detects the shift operation state by measuring.

The main magnet 300 is mounted to have a height difference on one side of the outer circumferential surface of the control finger 200 to move integrally with the control finger 200, the main detection sensor 500 is mounted to the sensing unit 400 to control the finger ( It is configured to detect both the magnetic field polarity change and the magnetic field strength change of the main magnet 300 generated by the movement of the 200. At this time, since the main magnet 300 is disposed to be spaced apart from the sensing unit 400 by a predetermined interval, as shown in FIG. Noise is prevented and more stable operation is possible.

The main magnet 300 includes first and second magnet modules 310 and 320 in which a plurality of magnets 301 and 302 are arranged in line, and the first and second magnet modules 310 and 320 respectively have different polarities and different polarities. It has a magnet arrangement state with a height difference. That is, the first and second magnet modules 310 and 320 may be formed to have two heights of different combinations of three levels of low stage, middle stage, and high stage, respectively, and accordingly, as illustrated in FIG. The vertical separation distance from the main detection sensor 500 of the 400 is formed with values of X1, X2, and X3, respectively.

In more detail, the first and second magnet modules 310 and 320 are each formed in a form in which a plurality of magnets 301 and 302 are arranged in a line along the linear movement direction of the control finger 200, and the rotation of the control finger 200 is performed. It is arranged to be spaced apart from each other along the direction of movement. Each of the magnet modules 310 and 320 may be formed in a separate type in which a plurality of magnets magnetized independently are arranged in a row, or alternatively, may be formed in a shape in which a plurality of polarities are magnetized through a magnetizing method in one body. . In this case, the plurality of magnets constituting each of the magnet modules 310 and 320 are arranged to have different polarity combinations. Accordingly, when the control finger 200 moves, the polarity of the magnetic field by the magnets detected by the main sensing sensor 500 is changed. Will change. Therefore, the movement state of the control finger 200 and the shift operation state of the transmission may be sensed by detecting the change in the magnetic field polarity.

In addition, the magnet modules 310 and 320 are formed to have different height differences. As shown in FIGS. 2 and 4, the first magnet module 310 is disposed such that a plurality of magnets have a low stage height and a high stage height. The second magnet module 320 may be arranged such that the plurality of magnets have a middle height and a high height. When the control finger 200 is moved by the height difference, the vertical separation distance between each magnet and the main sensing sensor 500 is changed. Accordingly, the strength of the magnetic field by the magnet detected by the main sensing sensor 500 is changed. Will change. Therefore, the movement state of the control finger 200 and the shift operation state of the transmission may be sensed by detecting the change in the magnetic field strength.

That is, the shift operation detecting apparatus according to the first embodiment of the present invention is formed such that the first magnet module 310 and the second magnet module 320 have different polarities and different height differences, and thus the polarity of the magnetic field. It is configured to detect both the change and the intensity change to detect the shift operation state.

As shown in FIG. 4, the first and second magnet modules 310 and 320 are mounted to be partially exposed to one side of the outer circumferential surface of the control finger 200. That is, the magnet seating groove 210 formed along the linear movement direction of the control finger 200 is formed on the outer circumferential surface of the control finger 200 to correspond to the number of magnet modules, and each magnet in the magnet seating groove 210. The module is inserted and coupled. In the state in which each of the magnet modules 310 and 320 is inserted into the magnet seating groove 210, a separate support plate 220 attaches a screw (T) to one end of the control finger 200 to fix and support the magnet modules 310 and 320. Are combined through. In this case, the outer circumferential surface of the control finger 200 is formed to have a height difference corresponding to the magnet modules 310 and 320 so that the magnet modules 310 and 320 having a height difference can be stably coupled as shown in FIGS. 2 and 4. .

Meanwhile, a separate nonmagnetic block 330 may be coupled between the first magnet module 310 and the second magnet module 320 as shown in FIG. 4, and in this case, is mounted on the control finger 200. The groove 210 may be formed and coupled to be inserted into it. As shown in FIG. 5, the nonmagnetic block 330 is located close to the main sensing sensor 500 in a state in which a shift operation state of the transmission is a neutral shift stage, and the first magnet module 310 and the second magnet module are shown in FIG. 5. 320 is located close to the main sensing sensor 500 as the control finger 200 rotates in a state in which the shift operation state of the transmission is a driving shift stage or a reverse shift stage.

The sensing unit 400 includes a case body 410 having one side open to form an accommodation space therein, a case cover 420 coupled to an open surface of the case body 410, and the sensing unit 400. The PCB includes a PCB 430 disposed in the case body 410, and a support frame 440 connected to the connector pin 442 while supporting the PCB substrate 430. The support frame 440 and the PCB substrate 430 are coupled to each other through a screw T, and are mounted in the inner space of the case body 410 in a state where they are coupled to each other. In this case, the connector pin 442 of the support frame 440 is soldered and welded to be in electrical communication with the PCB substrate 430. The case cover 420 is provided with a connector portion 421 protruding from the outside to be inserted through the connector pin 442, thereby transmitting and receiving electrical signals with the external electronic device. Meanwhile, as shown in FIG. 3, the main sensing sensor 500 may include two Hall sensors 501 and 502, which are mounted on the PCB substrate 430 and disposed inside the case body 410. . In this case, a separate support groove 441 may be formed in the support frame 440 such that the hall sensors 501 and 502 are inserted and supported.

In this case, the two Hall sensors 501 and 502 constituting the main sensing sensor 500 may each include a level sensing Hall sensor 501 and a first sensing magnetic field strength of each magnet of the first and second magnet modules 310 and 320. And a polarity sensing hall sensor 502 that senses polarity of each magnet of the second magnet module 310 or 320. In this case, at a position adjacent to the level sensing hall sensor 501, a separate magnetic focuser 503 capable of focusing magnetic flux on the magnet is mounted, which is accommodated in the support frame 440 of the sensing unit 400. It can be mounted in a manner that is inserted into the groove 443. By the magnetic focuser 503, the level sensing hall sensor 501 operates more accurately.

The level sensing hall sensor 501 detects a change in magnetic field strength generated by a change in the vertical separation distance from an adjacent magnet, and as shown in FIG. 6A, when the nonmagnetic material is adjacent, the output state is zero. And, according to an embodiment of the present invention for the magnet module having a three-step height difference is configured so that the output state according to each height difference appears in three forms. That is, when located close to the magnet having a high step height, the vertical separation distance with the magnet is relatively short X1, the intensity of the magnetic field is relatively high, showing a high output value (H), and close to the magnet having a low step height In this case, since the vertical separation distance from the magnet is relatively long as X3 and the strength of the magnetic field is relatively low, it shows a low output value (L). Since the separation distance is medium at X2 and the strength of the magnetic field is also medium, it represents the intermediate output value (M).

The polarity detection hall sensor 502 detects a change in the polarity of the magnetic field generated by the change in the polarity of the adjacent magnets, and outputs a default default value when the nonmagnetic material is adjacent to each other, as shown in FIG. High power is output when the N pole is close, and low output value is output when the S pole is close. Of course, it may be configured to output a low output when the N pole is close, and a high output value when the S pole is close. Therefore, the polarity sensing hall sensor 502 can know the polarity (N pole or S pole) of the magnet close to each other according to the type of output value.

According to this configuration, the main sensing sensor 500 may detect the change in the magnetic field polarity and the change in the magnetic field strength of each magnet module 310 and 320 through two Hall sensors. Therefore, when the magnet module of the main magnet 300 moves along with the control finger 200 according to the shift operation state of the transmission, the main sensing sensor 500 detects the change in the magnetic field polarity and the intensity of the magnetic module. Can detect the current shift operation status.

At this time, by combining the output values for the magnetic field polarity change and the magnetic field strength change of the main magnet 300 is detected by the main sensor sensor 500 to detect the current shift operation state, the main magnet 300 each shift The combination of these output values is arranged differently for each operation state.

For example, as shown in FIG. 4, the first magnet module 310 includes one magnet 301 having a high stage height, three magnets 302 having a low stage height, and a second magnet module ( 320 may be composed of one magnet 302 having a high stage height and three magnets 302 having a middle height, and a plurality of magnets constituting each of the magnet modules 310 and 320 may be disposed to have different polarities. The arrangement state of the magnet is a combination of the magnetic field strength and the magnetic field polarity of the magnet detected by the main sensing sensor 500 in the shift operation state for the six driving shift stages, the reverse shift stage and the neutral shift stage of the vehicle transmission, respectively. It is configured to be formed differently.

The general structure for the shift operation state shown in FIG. 7 has a six-speed drive shift stage, a reverse shift stage and a neutral shift stage, in which the control finger 200 shifts the shift linearly for gear shift in the neutral state, and thereafter, As the selective rotation moves to the shift stage, a specific shift stage is selected.

Since the control fingers 200 are linearly moved and rotated in the respective steps in the same moving distance, the control fingers 200 always have the same position state according to the shift operation state. Accordingly, the arrangement state of the main magnet 300 and the main detection sensor 500 is arranged as shown in FIG. 8 in response to the movement state.

That is, the level sensing hall sensor 501 and the polarity sensing hall sensor 502 are arranged in a line along the linear movement direction of the control finger 200 as shown in FIG. 8, and the shift operation state of the vehicle transmission is the neutral shift stage. In the state is located in the interval between the first and second magnet module (310,320), when the shift operation state of the vehicle transmission is the driving shift stage or the reverse shift stage, the first magnet module according to the rotational movement of the control finger 200 Disposed to be in proximity to the 310 or the second magnet module 320.

In other words, the two Hall sensors 501 and 502 constituting the main sensing sensor 500 are located close to the nonmagnetic block 330 in a state of being separated from the first and second magnet modules 310 and 320 at the neutral shift stage. It simply outputs a reference value, and is located near to the first magnet module 310 or the second magnet module 320 in the traveling shift stage or the reverse shift stage, so that the magnetic field characteristics of the first magnet module 310 or The magnetic field characteristic by the second magnet module 320 is output.

In this case, as described above, the first magnet module 310 may include one magnet having a high stage height so as to detect six driving shift stages and shift operation states of the reverse shift stage and the neutral shift stage, respectively. 301, three magnets 302 having a low step height, and the second magnet module 320 is composed of one magnet 302 having a high step height, and three magnets 302 having a stopping height. Each of the magnets constituting the magnet module includes the magnets of the corresponding magnets detected by the level sensing hall sensor 501 and the polarity sensing hall sensor 502 in the shift operation state for the six driving shift stages, the reverse shift stage and the neutral shift stage. The combination of magnetic field strength and magnetic field polarity is arranged to be formed differently from each other.

For example, in the first magnet module 310, as shown in FIG. 8, one magnet 301 having a high stage height is disposed such that the S pole is exposed to the outside of the control finger 200 and has a low stage height. Three magnets 302 may be arranged such that the NSN poles are sequentially exposed. The second magnet module 320 is one magnet 301 having a high step height is arranged so that the N pole is exposed to the outside of the control finger 200, three magnets 302 having a suspension height is the SNS pole is sequentially May be arranged to be exposed. When the control finger 200 rotates and moves linearly in each shift operation state according to the arrangement state, the magnetic field strength and the magnetic field polarity detected by the level sensing hall sensor 501 and the polarity sensing hall sensor 502 are respectively. Since the combinations for the two have different arrangement combinations, the shift operation state for each shift stage can be detected.

The arrangement state of each shift stage is shown in FIG. 9, and the arrangement of magnets detected by the two Hall sensors 501 and 502 is shown in a table, and FIG. 11 shows two holes according to each shift operation state. Output signals for sensors 501 and 502 are shown graphically. As shown in FIGS. 9 and 10, the level sensing Hall sensor 501 is close to the N pole magnet 302 of the height of the middle of the second magnet module 320, and the polarity sensing Hall sensor ( 502 is located proximate the S pole magnet 302 of the height of the interruption of the second magnet module 320. Therefore, since the strength of the magnetic field detected by the level sensing hall sensor 501 corresponds to a medium level (M), the magnetic field is outputted, and the polarity of the magnetic field detected by the polarity sensing hall sensor 502 corresponds to the S pole. As a result, this will be output. That is, the signal combination output by the main sensing sensor 500 at the first speed shift stage is MS (magnetic field strength middle, polarity is S pole). At this time, the signal output by the polarity detection Hall sensor 502 also outputs a signal value of high output (H) or low output (S) around the default value (M), as described in Figure 6, but using the N pole Since the S pole can be measured, it is described here as outputting values of N, M, and S in order to avoid confusion with the level sensing hall sensor 501.

On the other hand, similarly, in the two-speed shift stage, the level sensing Hall sensor 501 is close to the S pole magnet 302 of the low height of the first magnet module 310, and the polarity sensing Hall sensor 502 is the first magnet module. It is located proximate to the low height N-pole magnet 302 of 310. Therefore, the magnetic field strength sensed by the level sensing hall sensor 501 corresponds to a low degree (L) and outputs it, and the magnetic field polarity sensed by the polarity sensing hall sensor 502 corresponds to the N pole and thus outputs it. . Accordingly, the signal combination output by the main sensor 500 at the second speed shift stage is LN (low magnetic field strength, polarity is N pole). In the same way, the output signal combination at the three-speed shift is MN, the output signal combination at the four-speed shift is LS, and the output signal combination at the five-speed shift is HS, at the six-speed shift. The output signal combination is HN, the output signal combination at the reverse shift stage is MM, and the output signal combination at the neutral shift stage is ZM. At this time, since the level sensing Hall sensor 501 is close to the nonmagnetic block 330 at the neutral shift stage, the output value corresponds to zero (Z).

Therefore, since the output signals of different combinations are generated at each shift stage through the arrangement of the magnets and the arrangement of the hall sensors 501 and 502, the shift detection state corresponding to each shift stage is thus detected. Of course, the magnet arrangement state described above is exemplary, and may be configured through various other combinations.

The shift operation detecting apparatus of the vehicle transmission configured as described above is configured to detect not only the polarity change but also the magnetic field strength change of a plurality of magnets, thereby relatively reducing the number of magnets for detecting all the shift stages. As a result, the structure can be simplified, and the structure is easier to manufacture and maintain.

Next, a shift operation detecting apparatus for a vehicle transmission according to a second exemplary embodiment of the present invention will be described with reference to FIGS. 12 to 21.

12 is a perspective view schematically showing a structure of a shift operation detecting apparatus for a vehicle transmission according to a second embodiment of the present invention, and FIG. 13 is a structure of a shift operation detecting apparatus for a vehicle transmission according to a second embodiment of the present invention. 14 is an exploded perspective view schematically illustrating a configuration of a sensing unit according to a second embodiment of the present invention, and FIG. 15 is a control finger and a main device according to a second embodiment of the present invention. FIG. 16 is a perspective view schematically illustrating an arrangement state of a sensing sensor, and FIG. 16 is a diagram illustrating an output form of a main sensing sensor according to a second exemplary embodiment of the present invention.

In the shift operation detecting apparatus for a vehicle transmission according to the second exemplary embodiment of the present invention, the main sensing sensor 500 measures the position of the control finger 200 in such a manner as to detect a change in the magnetic field strength of the main magnet 300, thereby shifting the shift. As an apparatus for sensing an operation state, a description will be given mainly of a configuration different from those described in FIGS. 1 to 11 in order to prevent duplication of description.

In this second embodiment, as shown in FIG. 12, the main magnet 300 is mounted to the sensing unit 400, and the main magnet 300 according to the change of the separation distance between the main magnet 300 and the control finger 200. It is configured to detect the shift operation state in a manner that the main sensor 500 detects the magnetic field change of the.

That is, the main magnet 300 is mounted to the sensing unit 400 so as to be spaced apart from the control finger 200, and the control finger 200 changes the vertical separation distance from the main magnet 300 according to the rotational movement and the linear movement state. Surface height of the outer circumferential surface is formed to be different from each other, and the main detection sensor 500 is formed to detect a change in the magnetic field strength of the main magnet 300 generated according to a change in the vertical separation distance between the control finger 200 and the main magnet 300. do. For example, as shown in FIG. 13, the height of the outer circumferential surface of the control finger 200 is a vertical separation distance from the main magnet 300 as X1, X2, and X3 as the control finger 200 rotates and moves linearly. It can be formed to change to.

In more detail, the main magnet 300 is composed of two magnets 303 mounted on the sensing unit 400, the main sensor 500 detects the change in the magnetic field strength for each of the two magnets (303) And two level sensing Hall sensors 504 and 505 respectively disposed between the two magnets 303 and the control finger 200. At this time, the control finger 200 is formed so that the vertical separation distance with the two magnets 303, which change in accordance with the rotational movement and linear movement, respectively have different combinations, and these combinations appear differently in each shift operation state. It is formed to.

For example, the control finger 200 includes a neutral region 220 disposed closest to the main magnet 300 in a state in which a shift operation state of the vehicle transmission is a neutral shift stage, and a control centered on the neutral region 220. A first rotation region 230 and a second rotation region 240 are formed on both sides along the rotational movement direction of the finger, respectively, and the first rotation region 230 and the second rotation region 240 are control fingers, respectively. It may be stepped to have a plurality of divided surfaces 201, 202, 203 along the linear movement direction of 200.

At this time, the dividing surfaces 201, 202 and 203 are formed to have the dividing surfaces 201, 202 and 203 having three heights of the low stage, the middle stage and the high stage, as shown in FIGS. The region 230 and the second rotation region 240 are formed differently. For example, the first rotating region 230 and the second rotating region 240 may be formed to have four divided surfaces 201, 202, and 203, respectively. The first rotating region 230 may have a divided surface having a low height ( 203, the dividing surface 201 of the high stage height, the dividing surface 202 of the middle stage height, and the dividing surface 203 of the high stage height may be configured to be sequentially disposed along the linear moving direction of the control finger 200, The second rotational region 240 is divided into the low step height dividing surface 203, the middle step dividing surface 202, the high step dividing surface 201 and the low step high dividing surface 203 of the control finger 200. It may be configured to be disposed sequentially along the linear movement direction (see Fig. 18).

In addition, the neutral region 220 may be formed as one surface having one of three heights of the low, middle, and high stages of the first rotation region 230 and the second rotation region 240. For example, it may be formed of one surface having a high stage height as shown in FIGS. 13 and 15.

On the other hand, the two magnets 303 of the main magnet 300 are arranged in a line along the linear movement direction of the control finger 200, and close to the neutral region 220 when the shift operation state of the vehicle transmission is the neutral shift stage. In a state where the shift operation state of the vehicle transmission is a driving shift stage or a reverse shift stage, the vehicle transmission is positioned close to the first rotation region 230 or the second rotation region 240 according to the rotational movement of the control finger 200. Is placed.

Therefore, the vertical separation distance between the main magnet 300 and the outer circumferential surface of the control finger 200 changes according to the rotational movement and the linear movement of the control finger 200 according to the shift operation state of the vehicle transmission, and the main magnet 300 The combinations of the vertical separation distances corresponding to the two magnets 303 constituting each other are different from each other. Therefore, by combining the output signals of the two level detection Hall sensors 504 and 505 respectively detecting the change in the magnetic field strength by the two magnets 303, it is possible to detect the respective shift operation state.

As such, the material of the control finger 200 is preferably formed of a ferromagnetic material in order to change the magnetic field strength of the main magnet 300 according to a change in the vertical separation distance between the main magnet 300 and the control finger 200. For example, it can be made of carbon steel (SM45C) or chromium-molybdenum alloy steel (SCM series), as well as cast iron (FCD600), and a variety of other metals.

The sensing unit 400 is configured in the same form as the first embodiment, but a separate magnet support groove (not shown) will be formed to insert and seat the main magnet 300 on the bottom surface of the support frame 440. Therefore, detailed description of the sensing unit 400 will be omitted.

17 is a conceptual diagram conceptually illustrating a rotational movement and a linear movement state according to a shift operation state of a control finger according to a second embodiment of the present invention, and FIG. 18 is a main sensing sensor according to a second embodiment of the present invention; 19 is a conceptual diagram conceptually illustrating an arrangement state of a control finger, and FIG. 19 is a conceptual diagram conceptually illustrating an arrangement state change of a main sensing sensor and a control finger according to a shift manipulation state of a control finger according to a second embodiment of the present invention; 20 is a diagram showing the arrangement of changes in the arrangement state of the main sensing sensor and the control finger shown in FIG. 19, and FIG. 21 is the main sensing according to the arrangement changes of the arrangement of the main sensing sensor and the control finger shown in FIG. 19. A graph showing the output state of the sensor.

The control finger 200 according to the second embodiment of the present invention has a rotary motion and a linear motion according to the shift operation state as shown in FIG. 17, which is the most common form as in the first embodiment.

Since the control fingers 200 are linearly moved and rotated in the respective steps in the same moving distance, the control fingers 200 always have the same position state according to the shift operation state. Accordingly, the arrangement state of the main magnet 300 mounted on the sensing unit 400 and the outer peripheral surface dividing surfaces 201, 202, 203 of the control finger 200 is disposed as shown in FIG. 18 in response to the movement state. In FIG. 18, the position of the main sensing sensor 500 is illustrated instead of the main magnet 300, but two magnets 303 constituting the main magnet 300 and two level sensing hall sensors constituting the main sensing sensor 500 ( 504 and 505 are arranged in a line up and down, respectively, so that the same position with respect to the control finger 200 in the figure as shown in FIG.

That is, the two magnets 303 of the main magnet 300 and the two level sensing hall sensors 504 and 505 of the main sensing sensor 500 are arranged in a line along the linear movement direction of the control finger 200. When the shift operation state is located near the neutral region 220 in the state of the neutral shift stage, and the shift operation state of the vehicle transmission is the driving shift stage or the reverse shift stage, the first rotation is performed according to the rotational movement of the control finger 200. It is disposed to be in proximity to the region 230 or the second rotation region 240. In this case, the two magnets 303 and the two level sensing Hall sensors 504 and 505 are divided in the first rotation region 230 and the second rotation region 240 according to the linear movement and the rotation movement of the control finger 200. Disposed to correspond to surfaces 201, 202, and 203, respectively.

Therefore, when the control finger 200 rotates and moves linearly according to the shift operation state of the vehicle transmission, the control finger 200 closest to the two magnets 303 as shown in FIG. 19 at each shift stage. Combination arrangements for the dividing surfaces 201, 202, and 203 are formed in various ways, and thus the intensity of the magnetic field by the two magnets 303 is changed, which is detected by the two level sensing hall sensors 504, 505, and the corresponding output value is changed. Is output.

As described above, the control finger 200 has a first rotational region 230 and a second rotational region 240 around the neutral region 220, and the neutral region 220 has one surface having a high height. The first rotational region 230 is a split surface having a low stage, a high stage, a middle stage, and a low stage height is sequentially disposed along the linear movement direction of the control finger 200, and the second rotation region 240 is a control finger. The dividing surfaces of the low stage, the middle stage, the high stage, and the low stage height are sequentially disposed along the linear moving direction of the 200.

Therefore, in the first speed shift stage, as shown in FIG. 19A, two level sensing hall sensors 504 and 505 are disposed in close proximity to the second rotation region 240. The first level sensing hall sensor 504 of 504, 505 is located close to the high stage height dividing surface 201, and the second level sensing hall sensor 505 is located close to the low stage height dividing surface 203. . Accordingly, since the magnets 303 disposed up and down in correspondence with the first level sensing hall sensor 504 are positioned close to the dividing surface 201 of the high stage height, the vertical separation distance is relatively short, so that the magnets 303 The magnetic field strength is relatively high, whereby the first level sensing hall sensor 504 exhibits a high output value H. On the other hand, since the magnets 303 arranged up and down in correspondence with the second level sensing hall sensor 505 are positioned close to the dividing surface 203 having a low stage height, the vertical separation distance is relatively long, so that the magnets 303 The magnetic field strength appears to be relatively low, so that the second level sensing hall sensor 505 exhibits a low output value (L). Therefore, the combination of the signals output by the main sensing sensor 500 at the first speed shift stage is an HL signal.

In the same manner, in the two-speed shift stage, as shown in FIG. 19B, two level sensing hall sensors 504 and 505 are respectively divided with the dividing surface 202 and the low end of the first rotation region 230. Since they are each located close to the dividing surface 203 of the height, the combination of the output signals is an ML (middle output value M and low output value L) signal. The output signal combinations appear in the same way in the other gears: the MH signal in the three-speed shift, the HM signal in the four-speed shift, the LM signal in the five-speed shift, the LH signal in the six-speed shift, and the reverse. The LL signal is shown at the gear stage and the HH signal is shown at the neutral gear stage. These all represent different combination arrangements, and these output signals can detect the respective shift operation states.

Accordingly, the shift operation detecting apparatus for a vehicle transmission according to the second exemplary embodiment of the present invention is simply formed to have a height difference and has a simple structure corresponding to the outer peripheral surface of the control finger 200 without having various various magnetic modules or sensors. The main magnet 300 and the main sensing sensor 500 may be provided to detect shifting states of all shift stages.

Next, a shift operation detecting apparatus for a vehicle transmission according to a third exemplary embodiment of the present invention will be described with reference to FIGS. 22 to 32.

In the shift operation detecting apparatus for a vehicle transmission according to the third exemplary embodiment of the present invention, the main sensing sensor 500 measures the position of the control finger 200 in such a manner that the magnetic field polarity change of the main magnet 300 is measured, thereby shifting the shift. As an apparatus for sensing an operation state, a description will be given mainly of a configuration different from those described in FIGS. 1 to 11 in order to prevent duplication of description.

The main magnet 300 is formed in a mixture of a plurality of magnets 302 and the nonmagnetic block 305 is mounted on one side of the outer peripheral surface of the control finger 200 to move integrally with the control finger 200, the main sensing The sensor 500 is mounted on the sensing unit 400 and configured to detect a change in the polarity of the magnetic field of the main magnet 300 generated by the movement of the control finger 200. At this time, since the main magnet 300 is spaced apart from the sensing unit 400 by a predetermined distance X, as shown in Figure 23, it is maintained in a non-contact state with each other, so that the friction between each other during the gear shift Damage and noise are prevented for more stable operation.

The main magnet 300 includes first and second mixed magnet modules 340 and 350, each of which has a plurality of magnets 302 arranged in a line and a nonmagnetic block 305 is inserted between the plurality of magnets 302. The first and second mixed magnet modules 340 and 350 have magnet arrangement states of different polarities, respectively, and are configured such that the nonmagnetic blocks 305 are inserted at different positions.

In more detail, as illustrated in FIG. 25, the first and second mixed magnet modules 340 and 350 may have a plurality of magnets 302 and nonmagnetic blocks 305 along the linear movement direction of the control finger 200, respectively. It is formed in a line arrangement, it is arranged to be spaced apart from each other along the rotational movement direction of the control finger 200. For example, the first and second mixed magnet modules 340 and 350 may be configured such that four magnets and one nonmagnetic block are arranged in a line. At this time, the polarity arrangement state of each magnet and the position of the nonmagnetic block are formed differently.

That is, the first mixed magnet module 340 is configured in a form in which two magnets 302, a nonmagnetic block 305, two magnets 302 are arranged in a line, as shown in Figure 25, the second mixing The magnet module 350 may be configured in a form in which one magnet 302, a nonmagnetic block 305, and three magnets 302 are arranged in a line. If the polarity of the nonmagnetic block 305 is expressed as M, which is a neutral polarity, the polarity arrangement state of the first mixing magnet module 340 constitutes the arrangement state of SNMSN, and the polarity arrangement state of the second mixing magnet module 350 is The deployment status of SMNSS can be achieved.

The main sensing sensor 500 includes two polarity sensing hall sensors 506 and 507 for sensing the polarity of each of the magnets of the first and second mixed magnet modules 340 and 350. That is, in the third embodiment, since the vertical separation distance change due to the height difference does not occur between the main magnet 300 and the main sensing sensor 500, the magnetic field strength change of the main magnet 300 does not occur, and the control finger does not occur. Since only the magnetic field polarity of the main magnet 300 is changed according to the rotational movement and the linear movement of the 200, the main sensing sensor 500 may include the polarity sensing hall sensors 506 and 507 capable of detecting such a magnetic field polarity change. Apply.

The shift operation detecting apparatus of the vehicle transmission according to the third embodiment may also detect all six driving shift stages, the reverse shift stage and the neutral shift stage of the vehicle transmission as in the first and second embodiments described above. As such, the magnetic field polarity combinations of the first and second mixed magnet modules 340 and 350 sensed by the two polarity sensing hall sensors 506 and 507 are arranged differently at all shift stages.

For example, the first and second mixed magnet modules 340 and 350 are arranged to have different magnetic field polarities in a form in which a plurality of magnets 302 and nonmagnetic blocks 305 are mixed as described above, and two polarities are arranged. The sensing hall sensors 506 and 507 are arranged in a line along the linear movement direction of the control finger 200 as shown in FIG. 26, and each of the magnets 302 and the nonmagnetic blocks of the first and second mixed magnet modules 340 and 350. 305 is configured to sense the polarity. In addition, the two polarity sensing Hall sensors 506 and 507 are positioned in a section between the first and second mixed magnet modules 340 and 350 in a state in which a shift operation state of the vehicle transmission is a neutral shift stage, and the shift operation state is a traveling shift stage or the like. In the reverse shift stage, the control finger 200 is disposed to be located close to the first mixing magnet module 340 or the second mixing magnet module 350 in accordance with the rotational movement of the control finger 200. The output signals of the polarity sensing hall sensors 506 and 507 are configured to represent three-stage output signals according to the magnet polarity as shown in FIG. 27.

The control finger 200 according to the third embodiment of the present invention rotates and linearly moves as shown in FIG. 28 according to a shift operation state having a six speed shift stage, a reverse shift stage, and a neutral shift stage. The first and second mixed magnet modules 340 and 350 are arranged such that the magnetic field polarities sensed by the two polarity sensing hall sensors 506 and 507 form different combinations according to the shift operation state.

For example, as described above, the first mixed magnet module 340 is mounted such that the plurality of magnets 302 and the nonmagnetic block 305 form the polarity arrangement of the SNMSN, and the second mixed magnet module 350 is A plurality of magnets 302 and nonmagnetic blocks 305 may be mounted to achieve the polarity arrangement of the SMNSS. In this case, the two polarity sensing Hall sensors 506 and 507 are disposed in a section between the first and second mixing magnet modules 340 and 350.

The arrangement state of each shift stage is shown in FIG. 30, and the magnet arrangement state detected through the two polarity sensing hall sensors 506 and 507 is shown in a table, and FIG. Output signals for the two polarity sensing Hall sensors 506 and 507 are shown graphically. At the first speed shift stage, the first polarity sensing hall sensor 506 is close to the N pole magnet 302 of the second mixed magnet module 350, and the second polarity sensing hall sensor 507 is the second mixed magnet module. It is located close to the S-pole magnet 302 of (350). Accordingly, each hall sensor 506 and 507 outputs a corresponding magnetic field polarity output signal, and this output signal combination is NS. Similarly, in the two-speed shift stage, the first polarity sensing hall sensor 506 is close to the nonmagnetic block 305 of the first mixing magnet module 340, and the second polarity sensing hall sensor 507 is the first mixing. It is located close to the S-pole magnet 302 of the magnet module 340. Therefore, the output signal combination at the two-speed shift stage is MS (M is a polarity neutral state). In the same way, the output signal combination in each gear is MN in the 3rd gear, NM in the 4th gear, SM in the 5th gear, SN in the 6th gear, and in the reverse gear. SS, the neutral shift stage will show the MM signal.

Since the output signal combinations of all the gear stages are different from each other, it is possible to detect the shift operation state for each gear stage.

Therefore, the shift operation detecting apparatus for a vehicle transmission according to the third exemplary embodiment of the present invention forms the main magnet 300 by mixing a plurality of magnets and nonmagnetic blocks, thereby detecting the magnetic field polarity detected by the main sensing sensor 500. The change state can have three states: N pole, S pole, and neutral polarity (M), which makes it possible to create different output signal combinations for each shift in a simpler and more compact form, thus making it simpler. The structure makes it possible to detect the shift operation status for all shift stages.

On the other hand, the vehicle backup lamp is turned on / off according to the shift operation state detected by the shift operation detection device of the vehicle transmission described above, all of the shift operation detection apparatus according to the present invention in accordance with the change in magnetic field strength or polarity change Since the main detection sensor 500 indicating the stepped output signal is applied, by transmitting the output signal of the main detection sensor 500 to the vehicle control unit (not shown), the vehicle backup lamp on / off without additional devices It can be configured to work. That is, the backup signal of the main sensor 500 shown in the reverse shift stage (the output signal is represented as an electrical signal of a specific voltage range as described in Fig. 6, see Figs. 6, 16, 27). The on / off operation of the lamp can be easily controlled.
