It generates different shift range signals according to the state. The shift lever device 20 includes a body housing 100, a shift lever 200, and a shift detection unit 500.

The body housing 100 is fixedly coupled to the steering column 10, and an accommodation space is formed therein so that one end of the shift lever 200 is rotatably coupled to the inside of the body housing 100. In addition, the shift detection unit 500 for detecting a shift range signal by the shift lever 200 is also provided inside the main body housing 100. The body housing 100 may be separated into the lower body housing 100 and the upper body housing 100 as shown in Figure 2, one side so that the shift detection unit 500 is electrically connected to the outside. The connector connection portion 121 is formed.

The shift lever 200 is rotatably coupled to one end of the main body housing 100 so as to select and operate the shift range. More specifically, in the shift automatic mode, parking (P), reverse (R), and neutral ( The main body housing 100 is rotatably coupled to the inside of the main body housing 100 in order to select and operate the shift range of N) and the driving D, and the up / down shift operation in the shift manual mode. The inside is rotatably coupled in the vertical direction. In addition, the other end of the shift lever 200 is equipped with a separate operation knob 300 to facilitate the user's operation.

Looking at the rotation coupling structure of the shift lever 200 and the body housing 100 in more detail, first, a separate rotation coupling block 210 is provided at one end of the shift lever 200 for the rotation function of the shift lever 200. Is mounted, this rotary coupling block 210 is formed with an operation protrusion 211 is coupled to the moving block 570 to be described later. In addition, the inside of the body housing 100 is equipped with a separate moving coupling block 400 surrounding the outside of the rotary coupling block 210, the shift lever 200 is a rotary coupling block 210 is a moving coupling block ( It is rotatably coupled to the body housing 100 in a form coupled to 400. That is, the movable coupling block 400 is formed with a vertical rotation protrusion 401 forming an axis in the vertical direction so that the shift lever 200 can rotate in the front-rear direction, and the vertical rotation protrusion 401 is the main body housing 100. It is rotatably coupled therein and thus the shift lever 200 may rotate in the front-rear direction along with the movable coupling block 400 about the vertical rotation protrusion 401. In addition, horizontal rotation protrusions 212 forming a horizontal axis are formed on both sides of the rotation coupling block 210 so that the shift lever 200 may rotate in the vertical coupling direction in the movement coupling block 400. Correspondingly, the horizontal rotating protrusion 212 is inserted into the corresponding 400 and the horizontal rotating hole 402 is formed to rotate. Therefore, the shift lever 200 may rotate in the vertical direction while the horizontal rotating protrusion 212 rotates about the horizontal rotating hole 402. In other words, the shift lever 200 rotates in the front-rear direction along with the movable coupling block 400 about the vertical rotation protrusion 401 of the movable coupling block 400, and the horizontal rotation of the rotary coupling block 210. The protrusion 212 is coupled to rotate in the vertical direction in the movement coupling block 400 with a central axis.

The shift detection unit 500 is configured to generate a shift range signal by detecting a rotation manipulation position of the shift lever 200 in a non-contact detection method, such as a main printed circuit board 510, a rotation block 520, and a main magnet. 530 and the main sensing sensor 540.

The main printed circuit board 510 is mounted inside the main body housing 100, and a connector part 511 is formed at one side thereof and inserted into the connector connection part 121 of the main body housing 100. The main printed circuit board 510 is connected to make electrical communication with an external device such as a TCU through the connector unit 511. The main sensor 540 and the shift sensor 560 described later are connected to the main printed circuit board ( 510 is configured to transmit a sense signal to the TCU.

The rotation block 520 is mounted to the main body housing 100 so as to be positioned above the main printed circuit board 510, and is disposed to rotate in conjunction with rotation in the front and rear directions of the shift lever 200. That is, the rotation block 520 is engaged with the lower rotation coupling block 210 of the shift lever 200 and is configured to rotate forward and backward integrally with the rotation coupling block 210, which is illustrated in FIG. 2. As shown in FIG. 1, a protruding sleeve 111 in a vertical direction is formed, and a rotating center hole 521 is formed in the rotating block 520 such that the protruding sleeve 111 is inserted and rotatably coupled thereto. Therefore, when the shift lever 200 rotates in the front-rear direction, the rotation block 520 rotates in the front-rear direction together with the shift lever 200 about the protruding sleeve 111.

The main magnet 530 is coupled to the opposite of the center of rotation of the rotation block 520 is configured to rotate integrally with the rotation block 520. For example, as shown in FIG. 2, the rotation block 520 is formed in a fan shape and the rotation center hole 521 serving as the rotation center is formed to be located at the center of the fan shape. In this case, the main magnet 530 is formed. Is mounted on the fan outer peripheral surface of the rotary block 520 long along the circumferential direction may be configured to rotate in the front and rear direction with the rotary block 520.

The main sensor 540 is fixedly mounted on the main printed circuit board 510 to maintain a predetermined gap with the main magnet 530, and is configured to detect a change in the magnetic field due to the rotational movement of the main magnet 530. In this case, since the main magnet 530 and the main detection sensor 540 are arranged to be in contact with each other by a predetermined gap, the main magnet 530 does not generate friction and wear with the main detection sensor 540 even when the main magnet 530 rotates. to be.

Accordingly, when the shift lever 200 rotates in the front and rear directions to select and operate the shift range in the automatic shift mode, the rotation block 520 and the main magnet 530 rotate together with the shift lever 200. The change in the magnetic field according to the rotational movement of the magnet 530 is detected by the main sensor 540 to generate a signal for a shift range according to the corresponding rotational position and transmit the signal to the TCU of the vehicle.

On the other hand, such a shift detection unit 500 is configured to detect and generate a shift range signal by the operation of the shift lever 200 in the shift automatic mode as described above, in addition to the up / down shift signal in the shift manual mode. Separate detection block 570, the moving magnet 550 and the shift detection sensor 560 may be further included to detect the generated.

As described above, the shift lever 200 is rotatably coupled in the up and down direction to the inside of the main body housing 100 so as to perform an up / down shift operation in the shift manual mode. The moving block 570 is a main printed circuit board 510. Is disposed on the top of the) is configured to move linearly in conjunction with the vertical rotation of the shift lever (200). The movement block 570 is formed with a guide groove 571 such that the operation protrusion 211 of the rotation coupling block 210 described above is inserted and engaged, and thus the shift lever 200 is centered on the horizontal rotation protrusion 212. When rotated in the front-rear direction, the operation projection 211 also rotates in the front-rear direction about the horizontal rotation projection 212. At this time, the moving block 570 is configured such that the guide groove 571 is engaged with the operation protrusion 211 and linearly moved in a direction perpendicular to the vertical axis of rotation of the shift lever 200. A separate guide block 130 may be mounted inside the main body housing 100 to guide the linear movement of the moving block 570.

The moving magnet 550 is coupled to one side of the moving block 570 and configured to move linearly with the moving block 570 when the moving block 570 moves linearly, and the shift detection sensor 560 moves such a moving magnet 550. ) And is fixedly mounted on the main printed circuit board 510 to maintain a predetermined gap, and is configured to detect a magnetic field change due to the linear movement of the moving magnet 550. In this case, since the moving magnet 550 and the shift detection sensor 560 are disposed to be in contact with each other by a predetermined gap, the moving magnet 550 and the shift detection sensor 560 do not generate friction and wear with the shift detection sensor 560 even when the moving magnet 550 moves. .

Accordingly, when the shift lever 200 rotates in the up and down direction for the up / down shift operation in the shift manual mode, the moving block 570 and the moving magnet 550 move linearly together with the shift lever 200. In addition, the shift sensor 560 detects a change in the magnetic field according to the linear movement of the moving magnet 550, generates a signal for an up / down shift according to the corresponding moving position, and transmits the signal to the TCU of the vehicle.

3 to 6 are perspective views schematically showing an operating state of a shift detection unit detecting a shift range of a column type shift lever device according to an embodiment of the present invention, and FIG. 7 is a view illustrating an embodiment of the present invention. 8 is a conceptual diagram conceptually illustrating a shift sensing principle of a column type shift lever device, and FIG. 8 is a graph illustrating an operation state of a main sensing sensor of a column type shift lever device according to an exemplary embodiment of the present invention. 3 to 6 are perspective views of the lower side in a state in which the lower body housing 110 is removed while the shift lever device is assembled.

3 to 6 show the P shift range, R shift range, N shift range, and D shift range, respectively, by α angles from the P shift range state shown in FIG. It is operated by rotating in the front-back direction.

The shift lever 200 rotates about the vertical rotation protrusion 401 as described above, and in conjunction with the rotation block 520 rotates around the rotation center hole 521, one side of the rotation block 520 The main magnet 530 is mounted on the main magnet 530 also rotates with the rotation block 520.

The main magnet 530 may be configured such that magnets 531 and 532 adjacent to each other are multipole magnetized in a form having different polarities. For example, as shown in FIGS. 3 to 6, the N-pole magnet 531 is magnetized along one outer side of the rotating block 520, that is, the surface facing the main sensing sensor 540, and the remaining portion of the N-pole magnet 531. The S pole magnet 532 may be configured to magnetize in a section. The main sensor 540 is disposed outside the main magnet 530 to be spaced apart from the main magnet 530 by a predetermined distance, and may be composed of two linear hall sensors 541 and 542 for detecting magnetic field characteristics having different polarities. have. For example, the linear hall sensor 541 may sense a polarity of the S pole, and the linear hall sensor 542 may sense a polarity of the N pole.

3 is a diagram illustrating a P shift range state, in which the rotation state of the shift lever 200 is positioned at the same state as the reference line P1, and in this case, the relative positions of the main magnet 530 and the main detection sensor 540 are Both linear hall sensors 541 and 542 are located in close proximity to the N pole magnet 531. FIG. 4 illustrates an R shift range state. When the shift lever 200 rotates backward by an angle in the state shown in FIG. 4 in the state of FIG. 3, the two linear hall sensors 541 and 542 are both It moves away from the N pole magnet 531 and approaches the S pole magnet 532. FIG. 5 illustrates an N shift range state, and FIG. 6 illustrates a D shift range state. When the shift lever 200 sequentially rotates backward by an angle, two linear hall sensors 541 and 542 are provided. Is further away from the N pole magnet 531 and is located close to the S pole magnet 532.

FIG. 7 conceptually illustrates a relative position change state of the main magnets 530: 531 and 532 and the main sensing sensors 540: 541 and 542 according to the rotation of the shift lever 200, and N according to the change of each shift range. The pole magnet 531 moves away from the main sensing sensors 540: 541, 542 and the S pole magnet 531 approaches the main sensing sensors 540: 541, 542. In this case, the main sensing sensors 540: 541 and 542 may be configured to be disposed on magnetic contact boundary lines having different polarities in the N range state.

Therefore, when the main magnet 530 rotates backward by α angle, the linear hall sensor 541 for detecting the S polarity detects the proximity of the S polar magnet 532 and at the same time the linear hole for detecting the N polarity. The sensor 542 senses that the N-pole magnet 531 is far away. The main sensing sensors 540 and 541 and 542 configured as described above are configured to have linear output changes that increase or decrease proportionally, respectively, as shown in the output diagram of FIG. 8, which is the main sensing sensor 540 and 541 and 542. It may be programmed and implemented in a manner of changing the variables for the, since this method corresponds to a known technique for the Hall sensor, a detailed description thereof will be omitted.

8 illustrates a linear electrical signal output by the main sensor 540 (541,542). As shown in FIG. 8, the main sensor sensing different polarities generates a voltage output signal opposite to each other. This ensures reliable transmission range data by checking. In addition, the electrical signal by the main sensing sensor is transmitted to the control unit such as the TCU through the main printed circuit board 510, and it is determined which shift range is currently selected by the driver by comparing with a preset value stored in the TCU. In this way, transmission control is performed through appropriate hydraulic control.

That is, the TCU has a preset voltage reference value and compares the stored voltage reference value with a sensing signal input from the main sensor. Thereafter, the TCU compares a sensing signal input from the main sensing sensor with a preset stored reference value, and performs a determination step of identifying a predetermined shift range using the result obtained in the comparing step. Here, the comparing step is performed by comparing a plurality of input values inputted from the plurality of main sensing sensors with preset storage values, wherein the shift ranges determined by the respective results obtained in the comparing step are the same. If so, the TCU determines that the shift range determined in the determination step is the current shift range selected by the driver. On the other hand, when the shift ranges determined based on the result obtained in the comparison step have different values, the TCU may determine that the shift range in the previous step is still maintained, and may control the transmission accordingly.

As described above, in the column type shift lever device according to the exemplary embodiment of the present invention, the magnetic field change of the main magnet 530 that is rotated in the front and rear direction together with the shift lever 200 is not contacted by the main sensor 540. In this way, the signal for the currently selected manipulated shift range is accurately detected and generated.

9 to 11 are perspective views schematically showing an operation state of a shift detection unit that detects a shift operation state in a manual mode with respect to a column type shift lever device according to an embodiment of the present invention, and FIG. 12 is an embodiment of the present invention. A graph showing an operating state of a shift detection sensor of a column type shift lever device according to an embodiment of the present disclosure.

The shift detection unit 500 according to an embodiment of the present invention is configured to detect a signal for an up / down shift operation of the shift lever 200 in a shift manual mode and transmit the same to a control unit such as a TCU as described above. When the shift lever 200 rotates up and down, the shift block 570 and the shift magnet 550 linearly move, and the shift detection sensor 560 detects a change in the magnetic field caused by the linear shift of the shift magnet 550. It is configured to.

The moving magnet 550 is coupled to one side of the moving block 570. The magnets 551 and 552 having two different polarities are configured in a multipolar magnetization manner, and the two magnets 551 and 552 are movable blocks 570. Are arranged in a line along the linear movement direction. For example, as shown in FIGS. 9 to 11, the N pole magnet 551 is magnetized in front and the S pole in the rear with respect to the surface facing the shift detection sensor 560 along the moving direction of the moving block 570. The magnet 552 may be configured to be magnetized. The shift detection sensor 560 is disposed on the main printed circuit board 510 so as to be spaced apart from the moving magnet 550 by a predetermined distance, and as shown in FIGS. 9 to 11, one linear hall sensor 561 is disposed with each other. Two threshold hall sensors 562 and 563 that sense magnetic fields of different polarity. For example, one threshold hall sensor 562 for sensing the polarity of the north pole, one threshold hall sensor 563 for sensing the polarity of the south pole, and one pole for sensing the north pole or the south pole polarity. It may be composed of one linear Hall sensor 561. At this time, the linear hall sensor operates by outputting a continuous signal according to the strength of the magnetic force, and the threshold hall sensor outputs an on signal when the magnetic force is greater than or equal to a certain magnitude, and outputs an off signal when less than or equal to the predetermined magnitude. It operates in a manner, which corresponds to known techniques, and thus detailed description thereof will be omitted.

FIG. 9 illustrates a neutral state in which the up or down shift operation is not performed in the manual shift mode. In this case, the shift lever 200 is positioned at a reference position which is an intermediate point of the up and down rotation period. In this reference position, the shift detection sensor 560 includes one linear hall sensor 561 positioned on a magnet boundary line of different polarity of the moving magnet 550, as shown in FIG. The threshold hall sensor 562 is located close to the N pole magnet 551, and another threshold hall sensor 563 sensing S polarity is located close to the S pole magnet 552. . Accordingly, the linear hall sensor 561 generates a voltage output signal having a predetermined magnitude in this state, and the two threshold hall sensors 562 and 563 respectively generate on signals.

In this state, as shown in FIG. 10, when the shift lever 200 is rotated upward by β angle and upshifted, the movement block 570 moves to the right based on the direction shown in FIG. 10. One linear hall sensor 561 moves in a direction approaching the N-polar magnet 551 from the magnet boundary line of different polarity of the moving magnet 550 and detects the S-polarity. 563 moves from the S-pole magnet 552 close to the N-pole magnet 551. Therefore, when the linear hall sensor 561 is a type that detects the N polarity, the voltage output signal due to the magnetic force becomes larger, and the threshold hall sensor 563 that detects the S polarity weakens the strength of the magnetic force with respect to the S polarity. To output an off signal. Of course, the threshold hall sensor 562 that detects the N polarity outputs the ON signal as it is. On the other hand, if the linear hall sensor 561 is a kind that detects the S polarity, the voltage output signal due to the magnetic force will be smaller.

On the other hand, in the neutral state shown in FIG. 9, as shown in FIG. 11, when the shift lever 200 is rotated downward by the β angle and downshifted, the moving block 570 is leftward based on the direction shown in FIG. 11. Therefore, one linear hall sensor 561 moves in a direction close to the S-polar magnet 551 from a magnet boundary line of different polarity of the moving magnet 550, and detects N polarity. The three threshold hall sensors 562 move from the N-pole magnet 551 to the S-pole magnet 552. Therefore, when the linear hall sensor 561 is a type for detecting the N polarity, the voltage output signal due to the magnetic force is smaller, and the threshold hall sensor 562 for detecting the N polarity has a higher strength of the magnetic force with respect to the N polarity. It is weakened and outputs an off signal. Of course, the threshold hall sensor 562 that detects the S polarity outputs the on signal as it is. On the other hand, if the linear hall sensor 561 is a kind of sensing the N polarity, the voltage output signal due to the magnetic force will be larger.

FIG. 12 conceptually illustrates the magnitude of the voltage output signal according to the type of magnetic field acting on the linear hall sensor 561. As shown in FIG. 12, the shift lever 200 is in a neutral state (M0) in the shift manual mode. ), The output voltage signal of the linear hall sensor 561 may indicate a value of 0. When the shift lever 200 is in the up shift state M +, the output voltage signal of the linear hall sensor 561 may be represented by (). When the shift lever 200 is in the down shift state M−, the output voltage signal of the linear hall sensor 561 may indicate a negative value. The output voltage signal of the linear hall sensor 561 will appear opposite to each other in the case of sensing the N polarity and the kind sensing the S polarity.
