Description

[0001] Transmission control module [0002]

The present invention relates to a shift control module capable of controlling a shift.

Due to the development of automobile related technology, automobiles currently on the market are equipped with an automatic transmission.

Since these automatic transmissions transmit power through oil in the transmission, they have a lower energy consumption because they have a higher energy loss than manual transmissions having a direct transmission mechanism between the gears and the gears. To overcome such disadvantages of the automatic transmission, the shift lever is provided as an up-down (UP) mode as a separate manual mode in addition to the main speed change portion including the parking (P) -backward (R) -DOWN) mode, so that a maximum fuel economy can be improved by adjusting the number of shift stages according to the driving situation of the vehicle.

The manual operation unit includes a manual mode switch provided at a side of the main transmission to interlock with a lower end of the shift lever, and converts the operation state of the manual operation unit into an electrical signal and transmits the electrical signal to the automatic transmission control unit.

On the other hand, Japanese Patent Application Laid-Open No. 2001-105925 discloses a manual mode switch for operating a conventional manual operation unit. However, this prior art has a problem in that when the tiptronic switch is arranged in a horizontal state and the space around the shift lever is narrowed or designed to have a small width for a sophisticated design, it is difficult to install the tiptronic switch. Further, due to the engagement tolerance with the peripheral structure, there is a case where the operation of the manual mode is not properly performed due to the operation of the UP-DOWN system in a state in which the shift lever is not correctly entered into the manual operation unit There was a problem.

 That is, conventionally, whether or not the shift lever has been correctly entered into the manual operation unit and whether or not the UP-DOWN operation is operated are separately recognized, and even if the shift lever is not correctly entered into the manual operation unit, There is a fear that an unstable operation may be performed due to the expectation that the operation through the UP-DOWN operation will be performed.

Also, conventionally, as shown 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, the function of the contact part may be lost due to rusting or abrasion due to moisture.

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

The present invention provides a shift control module capable of sensing a manual shift mode and an automatic shift mode using a single Hall sensor capable of detecting the amount of magnetic force and the rotation angle.

The present invention also provides a shift control module that controls an up-down of a gear ratio according to a rotational direction of a shift lever when the manual shift mode is set.

The present invention also provides a shift control module capable of identifying a drive mode (D), a neutral mode (N), a reverse mode (R), and a parking mode (P) according to the rotational angle of the shift lever in the automatic shift mode I want to.

FIG. 2 is a perspective view of a shift control module according to an embodiment of the present invention, and FIG. 3 is a perspective view of a shift control module according to an embodiment of the present invention. 5 is a cross-sectional view of the shift control module according to an embodiment of the present invention (the shift bar is not lowered), and FIG. 6 is a front view of the shift control module, FIG. 7 is a perspective view of a guide bar of a shift control module according to an embodiment of the present invention, and FIG. 8 is a perspective view of a shift control module according to an embodiment of the present invention. 1 is a plan view of a rotary arm of a shift control module according to an embodiment.

As shown in FIG. 1, the transmission system 20 of the present embodiment includes a lever box 21 having an automatic transmission guide hole 211 and a manual transmission guide hole 212 formed at an upper portion thereof; A shift lever 22 coupled to the lever box 21; And a shift control module 10 coupled to the lever box 21.

The shift control module 10 of the present embodiment includes a housing 11, a printed circuit board 12 coupled to the inside of the housing 11, A lever module 14 rotatable in the housing 11 and coupled with a magnet 141 in the direction of the hall sensor 13, a lever module 14 coupled to the lever module 14, A spring (15) coupled to the spring (15); And a movement bar 16 for moving the lever module 14 such that the amount of magnetic force sensed by the hall sensor 13 changes. (See FIGS. 2 to 5)

The housing 11 is formed with an internal space, and includes a printed circuit board 12 and a Hall sensor 13 (see FIG. 5).

The Hall sensor 13 not only detects the amount of magnetic force, but also measures the rotation angle when the magnet 141 rotates.

The lever module 14 includes a guide bar 142 guided to the housing 11 and coupled to the magnet 141 at an end thereof; A through hole 1431 through which the guide bar 142 is inserted is formed and slid when the guide bar 142 moves in the direction of the housing 11 and rotates together with the guide bar 142 when the guide bar 142 rotates And a rotary arm 143.

The guide bar 142 is guided with the housing 11. And can be projected to the outside. That is, the guide bar 142 is guided with the housing 11. A magnet 141 is coupled to the distal end of the guide bar 142 and the magnet 141 faces the hall sensor 13 inside the housing 11. [

The guide bar 142 is guided by a rotary arm 143. A through hole 1431 is formed in the rotary arm 143. The through hole 1431 and the guide bar 142 are guided. The through hole 1431 is formed with a depressed portion 1432 and the guide bar 142 is formed with a protrusion guide portion 1421. The protrusion guide portion 1421 and the indent portion 1432 are engaged with each other. Therefore, the guide bar 142 can be guided in the through hole 1431 and can move in the longitudinal direction.

However, when the rotary arm 143 is rotated, the guide bar 142 also rotates together. At this time, the protrusion guide portion 1421 is inserted into the indentation portion 1432, so that the protrusion guide portion 1421 is engaged with the rotation arm 143 when the rotary arm 143 rotates.

Meanwhile, grooves may be formed in the guide bar 142 in the longitudinal direction, and protrusions corresponding to the grooves may be formed in the through holes 1431 so as to be engaged with the guide holes.

A spring (15) is coupled to the lever module (14). As a result, the spring 15 supplies the restoring force such that the lever module 14 is in a specific position. The spring 15 is positioned between the guide bar 142 of the lever module 14 and the housing 11 and the guide bar 142 is pushed out of the housing 11. [ The elastic force may be applied to the guide bar 142 so that the spring 15 pushes the guide bar 142 into the housing 11 as occasion demands.

When the shift lever 22 is moved to the left or right, a protrusion (not shown) coupled to the shift lever 22 pushes the shift bar 16 downward as shown in FIG. The inclined portion 161 of the movable bar 16 is pushed to the right while contacting the guide bar 142. As a result, the guide bar 142 of the lever module 14 moves in the direction of the hall sensor 13. The Hall sensor 13 senses a change in the magnetic force of the magnet 141 coupled to the end of the guide bar 142. In accordance with such magnetic force change, either the manual shift mode or the automatic shift mode is selected.

5 to 6 show a process in which the movable bar 16 is lowered and the guide bar 142 is moved in the direction of the hall sensor 13. FIG. In some cases, the movable bar 16 may be lowered to move the guide bar 142 away from the hall sensor 13.

1, when the shift lever 22 is moved back and forth, the rotary arm 143, which is in contact with the shift lever 22, rotates in a certain range of angles. This shift angle can be used to control the shift.

The shift control module 10 of the present embodiment may further include a control unit (not shown).

The control unit controls the shift based on information on the amount of magnetic force of the hall sensor 13 and information on the rotation angle of the magnet 141 (information measured from the hall sensor).

As described above, when the shift lever 22 is moved leftward and rightward, the magnet 141 is approached (see FIG. 6) or separated (see FIG. 5) by the hall sensor 13. Based on the change in the amount of magnetic force, the control unit selects either the automatic shift mode or the manual shift mode. For example, the state in Fig. 5 is an automatic shift mode. However, in the case of Fig. 6, the magnet 141 is close to the Hall sensor 13 and is in the manual shift mode.

The state of Fig. 5 is recognized by the control unit as the automatic shift mode. When the shift lever 22 is moved back and forth in the state of FIG. 5, the rotary arm 143 rotates in accordance with the moving direction and the degree of the shift lever 22. At this time, the hall sensor 13 can sense the rotation direction and the angle of rotation. The control unit recognizes that the rotary arm 143 is rotated in the counterclockwise direction by about 5 degrees and recognizes it as the neutral mode (N). When the control unit detects that the rotary arm 143 is rotated about 10 degrees counterclockwise, it senses the reverse mode R. [ When the control unit senses that the rotary arm 143 is rotated about 15 degrees in the counterclockwise direction, it senses it in the parking mode (R). When the control unit detects that the rotary arm 143 rotates about 5 degrees in the clockwise direction, it detects the drive mode (D). The setting of the automatic shift mode that is different from the rotation degree and direction of the rotary arm 143 is only one example.

In the state of Fig. 6, the control section recognizes the manual shift mode. In this case, since it is manually shifted, it is only necessary to know whether to shift to a high gear ratio or a low gear ratio (i.e., up-down). This is because the manual shift can be shifted one step up or one step down. In the state of Fig. 6, when the shift lever 22 is rotated back and forth, the rotary arm 143 also rotates counterclockwise or counterclockwise. When the rotary arm 143 rotates counterclockwise, the control unit increases (+) the gear ratio. On the other hand, when the rotary arm 143 rotates clockwise, the control unit decreases (-) the gear ratio. As described above, in the manual shift mode, if only the direction of rotation is recognized, the gear ratio can be increased or decreased.

As described above, the control unit selects either the manual shift mode or the automatic shift mode by using the change in the amount of the magnetic force sensed by the hall sensor 13. When the manual shift mode is selected, the gear ratio can be increased (+) or decreased (-) in accordance with the rotating direction of the rotary arm 143. When the automatic shift mode is selected, either the drive mode D, the neutral mode N, the reverse mode R, or the parking mode P can be selected according to the rotation angle of the rotary arm 143 .

As described above, the present invention can select the manual shift mode and the automatic shift mode using one Hall sensor 13. When the manual shift mode is selected, the gear ratio can be increased or decreased according to the rotational direction of the rotary arm 143. [ When the automatic shift mode is selected, the rotation angle of the rotary arm 143 is sensed to select either the drive mode D, the neutral mode N, the reverse mode R, or the parking mode P .

FIG. 9 is a perspective view of a shift control module according to another embodiment of the present invention, FIG. 10 is a side view of a shift control module according to another embodiment of the present invention, FIG. 11 is a perspective view of a lever module according to another embodiment of the present invention, FIG. 12 is a perspective view of a ring member of a lever module according to another embodiment of the present invention. FIG.

The shift control module 20 of the present embodiment includes a housing 21, a printed circuit board (not shown) coupled to the inside of the housing 21, A Hall sensor (not shown) A lever module 24 rotatable in the housing 21 and having a magnet (not shown) coupled to the hall sensor, a spring (not shown) coupled to the lever module 24, And a movement bar 26 for moving the lever module 24 such that an amount of a magnetic force sensed by the hall sensor changes.

The shift control module 20 of this embodiment has the same basic configuration as that of the shift control module 10 described with reference to Figs. The difference lies in the lever module 24, and the lever module 24 will be described in detail below.

The lever module 24 includes a rotary arm 243 coupled to the housing 21 so that the rotary shaft 2431 projects therefrom and is rotatable within a limited range; And a ring member 242 fixedly coupled to the rotation shaft 2431 in a state where a spring is coupled to the rotation shaft 2431.

The lever module 24 is composed of a rotary arm 243 and a ring member 242. The rotary arm 243 is coupled to the inside of the housing 21 so that the rotary shaft 2431 protrudes to the outside and is rotatable within a limited angle range in the housing 11 about the rotary shaft 2431. A ring member 242 can be fixedly coupled to the rotating shaft 2431. A magnet (not shown) is coupled to the rotary arm 243 located inside the housing 21. A Hall sensor is attached to the opposite side of the magnet.

When the movable bar 26 is lowered, the ring member 242 is brought into contact with the inclined portion of the movable bar 26, and the ring member 242 moves in the direction of the housing 21. At this time, the rotary arm 243 also moves into the housing 21. At this time, the magnet coupled to the rotary arm 243 moves in the direction of the Hall sensor, and the hall sensor senses a change in the amount of magnetic force.

Further, when the rotary arm 243 rotates, the Hall sensor measures the change of the magnetic force, and the rotary arm 243 measures the rotation angle. Based on this, the control unit (not shown) can select either the manual shift mode or the automatic shift mode. Further, in the manual shift mode, the gear ratio can be increased or decreased according to the rotating direction of the rotary arm 243. If the automatic shift mode is selected, the controller can select either the drive mode (D), the neutral mode (N), the reverse mode (R), or the parking mode (P) according to the rotation angle of the rotary arm (243).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. 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.
