Description

Non-contact transmission control module and transmission system using it {Transmission control module and system using it}

The present invention relates to a non-contact shift control module capable of controlling a shift in a non-contact manner and a shift system to which the shift is applied.

In general, due to the development of automobile-related technology, commercially available cars are equipped with automatic transmissions.

Since these automatic transmissions transmit power through oil in the transmission, they have higher energy loss and lower fuel economy than manual transmissions having a direct transmission mechanism between the gears. In order to make up for the disadvantages of the automatic transmission, the shift lever is a manual mode other than the main transmission unit consisting of parking (P) -reverse (R) -neutral (N) -driving (D). -DOWN) is provided to be linked to the manual operation unit operated by the way to adjust the number of gears for each driving situation to maximize the fuel economy.

The manual operation unit is provided on the side of the main transmission unit and includes a manual mode switch interlocking with the lower end of the shift lever, and converts its operation state into an electrical signal and serves to send the automatic transmission control unit.

On the other hand, Japanese Laid-Open Patent Publication No. 2001-105925 discloses a manual mode switch for operating a conventional manual operation unit. However, the prior art has a lot of problems in the space constraint that is difficult to be installed when the tiptronic switch is arranged in a horizontal state when the space around the shift lever is narrow or designed to form a small left and right width for a refined design. In addition, due to the coupling tolerance with the surrounding structure, the operation of the operation mode of the manual mode is frequently performed due to the operation of the up-down method while the shift lever is not correctly entered into the manual control unit. There was a problem.

That is, in the related art, whether the shift lever is correctly entered into the manual manipulation unit and whether the operation of the up-down method is recognized separately is recognized, even though the shift lever is not correctly entered into the manual manipulation unit. There was a problem that the unstable operation may be performed due to the expectation that the operation through the operation of the UP-DOWN method is performed.

In addition, conventionally, as in Korean Patent Registration No. 10-0913535, a shift signal is generated by a mechanical contact switch method. In the case of such a contact switch, its function may be lost due to rust or wear of the contact part due to moisture.

Therefore, it is time to develop a new type of contactless shift control module.

The present invention not only can select an automatic shift mode and a manual shift mode using a hall sensor, but also a non-contact shift control module that can select a shift mode of a gear by detecting an accurate position of a shift lever in an automatic shift mode and a shift to which the shift is applied.

Up and down, the control unit for selecting any one of the automatic transmission drive mode, neutral mode, reverse mode, parking mode according to the rotation angle detected by the second Hall sensor 141 when the automatic shift mode is selected (not shown) ).

The shift system 20 according to the present embodiment is a system for detecting a shift mode selected by a user according to a signal of the non-contact shift control module 10 and controlling a shift of the vehicle based on the shift mode. In particular, the non-contact shift control module 10 detects the movement of the shift lever 22 through a hall sensor. That is, since the movement of the shift lever 22 is detected in a non-contact manner, there is no mechanical friction in the sensor. Therefore, there is no fear of malfunction due to mechanical wear.

 The shift system 20 includes a lever box 21 having an automatic shift guide hole 211 and a manual shift guide hole 212 formed thereon; A lever lever 24 coupled to a side thereof, and a shift lever 22 coupled to a lower part of the lever box 21 so that the upper part rotates back, forth, left and right; And a non-contact shift control module 10 coupled to the lever box 21 (see FIG. 1).

As already known, the automatic transmission gear shifts gears automatically by placing the shift lever 22 in the automatic transmission drive mode. In addition, the shift lever 22 may be placed in the parking mode, the reverse mode, or the neutral mode. The automatic shift drive mode, the parking mode, the reverse mode, and the neutral mode are selected while the shift lever 22 moves the automatic shift guide hole 211 formed at the upper portion of the lever box 21.

On the other hand, when the shift lever 22 is located in the manual shift guide hole 212, the shift gear may be manually selected. In other words, if the shift lever 22 is moved to the upper position once, it is converted into a high speed gear by one step higher in the present, and if the shift lever 22 is moved to the lower position after being moved to the lower level, it is converted into a low gear gear being lowered from the current level. (See Figure 1)

The lower portion of the shift lever 22 is coupled to the lever box 21 so as to rotate. The upper portion of the shift lever 22 may flow back, front, left, and right with the lower axis. The lever magnet 24 is coupled to the side of the shift lever 22. When the lever magnet 24 is adjacent to the first hall sensor 13, the first hall sensor 13 detects the magnetic force of the lever magnet 24. When the shift lever 22 is moved in the manual shift mode, the first hall sensor 13 and the lever magnet 24 are adjacent to each other.

The non-contact shift control module 10 is coupled to the lever box 21. In the shift system 20 of the present invention, the shift mode can be selected in a non-contact manner by the function of the non-contact shift control module 10. Therefore, the non-contact shift control module 10 will be described in detail below.

The non-contact shift control module 10 includes a housing 11; A printed circuit board 12 coupled to the inside of the housing 11; A first hall sensor 13 coupled to the printed circuit board 12 and detecting the magnetic force when the lever magnet 24 coupled to the shift lever 22 is adjacent to the printed circuit board 12; A second hall sensor 141 coupled to the printed circuit board 12 and detecting a rotation of magnetic force; and a second coupler coupled to a position facing the second hall sensor 141 and rotatably coupled to the housing 11. A rotation sensing unit 14 including a hall sensor seat module 142; and one of a manual shift mode and an automatic shift mode by a magnetic force detection signal of the first Hall sensor 13, and the manual shift mode If selected, the gear shift up and down in accordance with the rotation direction detected by the second Hall sensor 141, and if the automatic shift mode is selected, the automatic shift drive mode according to the rotation angle detected by the second Hall sensor 141, And a control unit (not shown) for selecting any one of the neutral mode, the reverse mode, and the parking mode (see FIGS. 2 to 7).

As shown in Figure 1, the non-contact shift control module 10 is coupled to the side of the lever box (21). The non-contact shift control module 10 detects the movement of the shift lever 22 and selects a shift mode based on the shift.

As shown in Figure 2, the housing 11 provides a space for storing the parts therein. The printed circuit board 12 is coupled to the inside of the housing 11. This embodiment works electronically, requiring a printed circuit board 12. The housing 11 is covered with a cover 111.

As shown in FIG. 3, the first hall sensor 13 is coupled to the printed circuit board 12. The first hall sensor 13 reduces magnetic force when the lever magnet 24 coupled to the shift lever 22 is adjacent to the first hall sensor 13. When the first hall sensor 13 detects the magnetic force, the controller recognizes that the manual shift mode is selected.

As shown in FIG. 6, the rotation sensing unit 14 is coupled to the printed circuit board 12 to detect the rotation of the magnetic force, and the second hall sensor 141 and one side facing the second hall sensor 141. And a second hall sensor magnet module 142 rotatably coupled to the housing 11. As the second Hall sensor magnet module 142 rotates, the second Hall sensor 141 detects an accurate rotation angle of the second Hall sensor magnet module 142. The other side of the second hall sensor magnet module 142 contacts the shift lever 22. When the shift lever 22 moves back and forth, the magnet member 142 rotates.

The second Hall sensor magnet module 142 includes a second Hall sensor magnet 1421 and an arm member 1422. The arm member 1422 is in contact with the shift lever 22. Here, "contact" includes the case where a hole is formed in the shift lever 22 and the arm member 1422 is partially inserted into the hole, and the arm member 1422 is elastic in a specific rotational direction and shifts. The lever 22 also includes a case where it is arranged to rotate the arm member 1422 in the direction opposite to the elastic force.

In addition, as in another embodiment shown in Figure 8, the lower portion 321 of the shift lever 32, the extension member 323 is coupled to a portion of the shift lever 32, and extends when the shift lever 32 is moved. Member 3221 moves together. At this time, the arm member 1422 coupled to the groove of the extension member 3221 is also rotated together.

In the manual shift mode, as shown in FIG. 7, when the shift lever 22 moves to the left and the lever magnet 24 is adjacent to the first hall sensor 13, the first hall sensor 13 detects the magnetic force. .

In this case, the control unit, in the manual shift mode, up and down the gear shift in accordance with the rotation direction detected by the second hall sensor 141. For example, when the shift lever 22 is moved forward in the manual shift mode (when the first hall sensor 13 detects the magnetic force), the second hall sensor magnet module 142 rotates counterclockwise. The second hall sensor 141 detects the rotation direction, and the control unit shifts the gear by a high speed gear. In addition, when the shift lever 22 is moved backward in the manual shift mode (when the first hall sensor 13 detects the magnetic force), and the second hall sensor magnet module 142 rotates clockwise, the control unit Shift the gear to the next low gear.

The protruding member 23 may be interposed between the lever magnet 24 and the shift lever 22. In addition, as shown in FIG. 3, the first spring module 151 and the second spring module 152 are coupled to the inside of the housing 11 with the first hall sensor 13 interposed therebetween. As shown in FIG. 7, the protruding member 23 is adjacent to the first hall sensor 13 in the manual shift mode. At this time, the protruding member 23 is interposed between the first spring module 151 and the second spring module 152. In the manual shift mode, when the protruding member 23 moves back and forth, the protruding member 23 is again positioned at the origin (center) by the first spring module 152 or the second spring module 152. The lever magnet 24 coupled to the protruding member 23 is large enough to supply magnetic force to the first hall sensor 13 even when the protruding member 23 moves.

On the other hand, when the lever 22 moves to the right as shown in FIG. 6, the protruding member 23 is not positioned between the first spring module 152 and the second spring module 152. In the case of Fig. 6, the automatic shift mode is entered.

In the automatic shift mode, as shown in FIG. 6, the lever 22 is moved to the right in the manual shift mode of FIG. 7, so that the lever magnet 24 is spaced apart from the first hall sensor 13, so that the first hall sensor 13 is moved. When the magnetic force is not detected (or when the magnetic force is detected weaker than in the case of Figure 6).

In this case, the shift mode is determined according to the rotation angle detected by the second hall sensor 141. This is because the rotation angle of the second hall sensor 141 is the point where the lever 22 is located. For example, when the arm member 1422 rotates about 5 degrees in the counterclockwise direction with respect to the neutral mode, the reverse mode is entered. In addition, when the arm member 1422 rotates about 10 degrees in the counterclockwise direction with respect to the neutral mode, the parking mode is entered. On the other hand, when the arm member 1422 rotates about 5 degrees clockwise with respect to the neutral mode, the automatic transmission drive mode is obtained.

4 and 5 are front views of the non-contact shift control module 10 and the shift lever 22. When the upper portion of the shift lever 22 of FIG. 4 is pulled backward, as shown in FIG. 5, the shift lever 22 rotates slightly around the lower part, and at this time, the arm member 1422 rotates. As a result, the second Hall sensor magnet 1421 is rotated to change the direction of the magnetic force, the second Hall sensor 141 detects the rotation angle and the rotation direction of the magnetic force.

In this embodiment, by using the two Hall sensors, the accurate position of the shift lever 22 is detected without mechanical contact, and the control unit controls the shift based on this.

Modifications and additions by those skilled in the art to an equivalent range based on the embodiments will also fall within the scope of the present invention.
