1 is a perspective view showing the appearance of a vehicular transmission according to an embodiment of the present invention.

As shown, the vehicular transmission 1 according to the embodiment of the present invention may include a display unit 100, a shift lever 200, and a shift control unit 300.

The display unit 100 may display a shift pattern including at least one gear position. In an embodiment of the present invention, the shift pattern may include at least two layers. For example, A case in which the speed change stages are arranged in the same direction at positions adjacent to each other will be described as an example.

In this case, the shift stages included in the respective layers are arranged in the same direction in order to allow the shift lever 200 to move in any one direction in the embodiment of the present invention to select all of the shift stages included in the respective layers And a detailed description thereof will be given later. In addition, in the embodiment of the present invention, the case where the direction of arrangement of the gear positions included in each layer is the same as the moving direction of the shift lever 200 will be described as an example. However, The arrangement direction of the gear positions included in each layer may be different from the moving direction of the shift lever 200.

2 is a schematic diagram showing a shift pattern according to an embodiment of the present invention.

As shown, the shift pattern 400 according to the embodiment of the present invention includes a first layer 410 including P, R, N, D, and M stages and a second layer 410 including +, M, And the first layer 410 and the second layer 420 may be arranged in the same direction at positions adjacent to each other.

In the embodiment of the present invention, the shift pattern 400 includes the first layer 410 and the second layer 420. However, the number of layers and the number of layers included in each layer The speed change stages can be variously changed. In the embodiment of the present invention, the shift pattern 400 is composed of a plurality of layers such as the first layer 410 and the second layer 420. However, the present invention is not limited to this, And may be composed of at least one layer according to a pattern.

In the embodiment of the present invention, the first layer 410 and the second layer 420 of the speed change pattern 400 are all displayed. However, The present invention is not limited to this, and when another layer is selected in a state where only one layer among a plurality of layers is displayed, another selected layer may be displayed.

In this case, in FIG. 2, the gear stages included in the first hierarchical layer 410 and the gear stages included in the second hierarchical layer 420 are different from each other. That is, In order to make it possible. For example, in FIG. 2, the currently selected layer is the first layer 410, and the gear stages included in the first layer 410 have a relatively larger size than the gear stages included in the second layer 420 And displayed brightly.

In the exemplary embodiment of the present invention, the size and brightness of the gear stage are displayed differently to represent the currently selected layer among the first layer 410 and the second layer 420. However, The present invention is not limited to this, and it is also possible to display different colors or fonts in addition to the above-described size and brightness.

The display unit 100 may include an indication pattern 411 indicating the position pattern of the shift lever 200 according to the selection of each gear range stage on one side of the gear stages included in the first layer 410 and the second layer 420. [ , ≪ / RTI > 421). Here, the position pattern in the embodiment of the present invention indicates the positional relationship of the shift lever 200 when the shift lever 200 is moved to select a predetermined speed change stage. For example, A pattern in which the lever 200 is positioned as it is, a pattern in which the shift lever 200 returns to the position of the previous gear position after the gear position is selected, and the like.

For example, the instruction patterns 411 and 421 of the first hierarchical layer 410 and the second hierarchical structure 420 include the instruction patterns 411a and 421a highlighted respectively as shown in FIGS. 2 and 3, In the embodiment of the present invention, the shift lever 200 is directly positioned at the speed change stage where the highlighted design patterns 411a and 421a are selected, and the unlined patterns 411b and 421b are shifted to the previous shift position The case where the shift lever 200 is returned to the position of the shift lever 200 will be described. At this time, FIGS. 2 and 3 show an example in which the highlighted instruction patterns 411a and 421a are displayed in relatively thick lines.

In addition, in the embodiment of the present invention, the case where all the instruction patterns of the gear positions included in the non-selected hierarchy are displayed in dark will be described as an example.

In the shift pattern 400 described above, the first layer 410 may include a selected gear stage 412 for selecting the second layer 420, and in the embodiment of the present invention, the selected gear stage 412 And the second gear 420 is also provided with the same speed change stage 422 as the selected speed change stage 412 of the first hierarchy 410, And may indicate a selection relationship between the layer 410 and the second layer 420.

In the embodiment of the present invention, the case where one selection speed change stage 412 is provided is exemplified. However, the present invention is not limited to this, and the selection speed change stage 412 may be two or more, May be arranged in the same direction adjacent to the first layer 410.

That is, when the driver selects the M-th stage in the first hierarchy 410, the second hierarchy 420 is selected as shown in FIG. 3 in FIG. 2 described above, and the rendering mode can be displayed in the reverse order to FIG. 2 . In FIG. 3, the case where the selected hierarchy 412 is omitted in the first hierarchy 410 after the second hierarchy 420 is selected is described as an example for facilitating understanding of the present invention However, the present invention is not limited thereto. Unlike FIG. 3, the first hierarchy 410 may display the selected speed change stage 412 even after the second hierarchy 420 is selected.

In this case, when the driver selects the predetermined shift stage of the second hierarchy 420 continuously for a predetermined time or there is no operation of the shift lever 200 for a predetermined time, the first hierarchy 410 May be selected. However, this is merely an example for facilitating understanding of the present invention. The selection between the first layer 410 and the second layer 420 may be performed according to various conditions.

For example, when the driver selects the - / D step for a predetermined time or does not operate the shift lever 200 for a predetermined time while the second layer 420 is selected as shown in FIG. 3, the first layer 410 And the D stage is selected. In this case, in FIG. 2, it is displayed in the -lower stage and in FIG. 3, it is displayed in the - / D stage. In the embodiment of the present invention, when the stage is continuously selected for a predetermined time, And may be displayed in a non-step of the / D step.

" 형상을 가지나 제 2계층(420)이 선택된 상태에서 제 1계층(410)의 지시 패턴(411)은 "

"형상을 가지도록 하여 운전자로 하여금 현재 선택된 계층을 보다 쉽게 인지할 수 있도록 할 수도 있다.Meanwhile, it can be seen that the shape of the instruction pattern 411. 421 is changed according to the hierarchy selected in the above-described FIG. 2 and FIG. For example, when the first layer 410 is selected as shown in FIG. 2, the instruction pattern 411 of the first layer 410 is "

Quot; shape but the second layer 420 is selected, the instruction pattern 411 of the first layer 410 is "

Quot; shape so that the driver can more easily recognize the currently selected layer.

In addition, in the embodiment of the present invention, the display unit 100 may display a setting screen that allows the driver to make various settings in addition to the shift pattern 400 of FIGS. 2 and 3, Or the like may be displayed on the display unit 100 or may be separately provided.

For example, the display unit 100 may display a setting screen for setting the intensity of the operation force as shown in FIG. 4, and the driver may set the intensity of the operation force desired by the driver through the displayed setting screen.

That is, the user can set the intensity of the operation force such as SOFT, NORMAL, and HARD to the intensity of the desired operation force on the setting screen for setting the intensity of the operation force to be provided when the driver operates the shift lever 200.

In the embodiment of the present invention, the case where the driver 200 moves the shift lever 200 in a state where the setting screen is displayed and sets the desired speed to a desired value will be described. However, A jog shuttle, a button, or the like may be provided inside the vehicle.

In the embodiment of the present invention, the intensity of the operation force is set as the setting screen. However, the present invention is not limited thereto. For example, A screen for various settings can be displayed.

Although the display unit 100 is installed at one side of the shift control unit 200 in the embodiment of the present invention, the present invention is not limited to this example. For example, The HUD device may be used, or two or more may be used together.

The shift lever 200 may have a knob (not shown) serving as a knob at one end thereof. The driver can select a desired shift stage by moving the shift lever 200 in one direction by holding the knob . In the embodiment of the present invention, a case in which the shift lever 200 moves only in one direction to select a gear position of a shift pattern of at least two layers or more will be described as an example.

In other words, the gear stages included in the shift pattern are all included in the same hierarchy, and the driver moves the shift lever 200 in a plurality of directions such as the horizontal direction and the vertical direction to select a desired gear position, The shift lever 200 can be shifted only in one direction with respect to the shift pattern 400 composed of two layers as shown in FIG. 2, so that the shift stages included in the plurality of layers can be selected.

Therefore, since the driver can move the shift lever 200 only in any one direction to select the speed change stage, the space occupied by the vehicular transmission 1 is reduced, and the space utilization in the vehicle can be improved.

The transmission control unit 300 is connected to the shift lever 200 to control the movement of the shift lever 200 and to provide the operation force and to sense the position of the shift lever 200 to determine whether the normal shift has been performed have.

FIG. 5 and FIG. 6 are perspective views illustrating a shift control unit according to an embodiment of the present invention, and FIG. 7 is a perspective view illustrating a position sensing unit according to an embodiment of the present invention. 5 and 6, reference numerals for some components of the position sensing unit are omitted, but the same reference numerals as in FIG. 7 may be used for the omitted reference numerals.

A shift control unit 300 according to an embodiment of the present invention includes a shift control unit 310 and a shift lever 200 that are connected to the shift lever 200 to control the shift of the shift lever 200, And a position sensing unit 320 for sensing the position of the display unit 320.

The movement control unit 310 may include a drive unit 311 and a connection unit 312. The movement control unit 310 controls the movement of the shift lever 200 moving in one direction while rotating around the first rotation axis 210, 200 can be provided.

The driving unit 311 may include a fixed unit 311a and a moving unit 311b. In the embodiment of the present invention, a case where a voice coil motor is used as the driving unit 311 is described, for example, However, the present invention is not limited thereto, and various types of motors such as a DC motor, a stepping motor, and the like may be used.

The moving part 311b moves in one direction according to a control signal applied to the coil 311c wound around the fixed part 311a and the magnitude of the moving force or the force pattern may be changed according to the applied control signal .

The connecting portion 312 may be formed on one side of the moving portion 311b and may be connected to one end of the shift lever 200. One end of the shift lever 200 connected to the connecting portion 312 may be disposed around the second rotating shaft 312a It becomes possible to rotate. Accordingly, when one end of the shift lever 200 connected to the connecting portion 312 is moved when the shifting portion 311b moves, a force is applied to one end of the shift lever 200, and when the driver operates the shift lever 200, will be. For example, when the shifting portion 211b moves in a direction opposite to the shifting direction of the shifting lever 200, the driver must apply a greater force than the force of the shifting portion 311b to move the shifting lever 200, Can move.

Since the magnitude and the force pattern of the force of the moving part 311b moving in accordance with the control signal applied to the coil 311c of the fixed part 311a may be different from that of the shifting control part 310, The driver feels a sense of operation, thereby preventing selection or misoperation of the speed change stage.

For example, when the driver selects the adjacent gear position from the current gear position, the movement control unit 310 applies a control signal to provide the operating force as shown in FIG. 8, When a step is selected, a control signal for providing an operation force as shown in FIG. 9 is applied. In the case where the control signal is restored to its original position after selecting another gear, a control signal providing operation force as shown in FIG. 10 can be applied.

8 to 10, the "operating force" means a force applied to the shift lever 200 in accordance with the movement of the shift lever 200, and the positive value refers to a force applied to the shift lever 200 in relation to the shift direction of the shift lever 200 A negative value indicates a force applied in a forward direction with respect to the moving direction of the shift lever 200, and a "position" indicates a speed change stage selected by the shift of the shift lever 200. At this time, the force applied in the forward or reverse direction with respect to the moving direction of the shift lever 200 may be changed depending on the moving direction of the moving part 311b.

Hereinafter, the shift pattern of FIG. 2 described above with reference to FIGS. 8 to 10 will be described as an example.

8 is an operation force generated when the driver selects the adjacent speed change stage R from the current speed change stage N. The movement control unit 310 determines whether or not the shift lever 200 starts to move, A force is applied to the shift lever 200 in the opposite direction to the shift direction of the shift lever 200 and a force is applied in the forward direction to the shift direction of the shift lever 200 beyond the reference point P1, So that the stage can be selected. 8 illustrates a case where the force applied in the reverse direction and in the forward direction is increased to the peak value and then decreased, and then the force pattern is shaped like a hill shape. However, this is only an example for understanding the present invention, It is possible to have various force patterns depending on the operation force.

9 is an operation force generated when the other speed change stage P is selected from the current speed change stage N via one or more intermediate speed change stages R. The movement control section 310 selects the other speed change stage P (V1, V2) of the force applied in the reverse direction between the gear stages to which it is subjected. At this time, it can be seen that the magnitude of the force at the time point T1 at which the shift lever 200 is moved from the N-th stage to the R-stage and at the time T2 at which the shift lever 200 starts to move from the R-stage to the P- This is to inform the driver that at least one intermediate gear range is used. Here, a case where the force at T2 is set to be larger than the force at T1 will be described as an example in the embodiment of the present invention.

In other words, when the driver wants to select the P stage through the R stage from the N stage, if the R stage is selected and then the P stage is selected, The shift lever 200 can be moved. In the embodiment of the present invention, the magnitude of the force is different between T1 and T2. However, the present invention is not limited thereto. For example, The sizes may be the same. In the above-described FIG. 9, a case in which the force pattern between the gear stages increases to the respective peak values and then decreases is described as an example. However, the present invention is not limited thereto.

10 is a diagram showing an example of operation force generated when the shift lever 200 is shifted by the driver and the specific shift range is selected and then the shift lever 200 returns to the original position, The force can be continuously applied in the reverse direction until the shift lever 200 is returned to the original position N again. That is, when the driver moves the shift lever 200 from the N-th stage to the D-stage, a force is applied in a reverse direction in accordance with a predetermined force pattern with respect to the shifting direction of the shift lever 200, The shifting lever 200 is restored to the original position N by applying a force in a reverse direction to the shifting direction of the shifting lever 200 continuously. In this case, the arrow in FIG. 10 indicates the moving direction of the shift lever 200.

10, the case where the shift lever 200 moves from the N-th stage and selects the D-stage is illustrated as an example. As shown in Fig. 2, ), That is, the position pattern returning to the previous speed change stage, and the speed change stage in which the operating force of Fig. 10 is provided according to the position pattern of each speed change stage can be changed. 3, the second layer 420 has the instruction pattern 421a with the M-stage highlighted and the instruction pattern 421b with the + and - / D stages not highlighted. Therefore, in the second hierarchy 420, However, the shift lever 200 can be returned to the M-th stage after the -D / D stage is selected.

When the driver attempts to select the selected speed change stage 413 to select the second hierarchy 420 in the state where the first hierarchy 410 of FIG. 2 is selected, the movement control unit 310 determines In order to prevent the selection from being made, when the driver moves the shift lever 200 from the D-stage to the M-stage, the M-stage is selected only when the driver applies a greater force So that the erroneous operation can be prevented.

In addition, the movement control unit 310 may perform a shift lock function so that a specific shift range is selected only when a specific condition is satisfied. For example, when the driver wants to select the R-stage, the movement control unit 310 allows the movement unit 311b to move only when the speed of the vehicle is equal to or lower than a predetermined speed and depresses the brake pedal, So that occurrence of a vehicle accident can be prevented in advance.

The position sensing unit 320 may include a first rotating member 321, a second rotating member 322, and a sensing unit 323.

The first rotary member 321 rotates in one direction together with the first rotary shaft 210 of the shift lever 200 when the shift lever 200 rotates about the first rotary shaft 210 and the outer peripheral edge of the first rotary member 321 The first magnetic member 321a may be in contact with the second rotary member 322 and the first magnetic member 321b may be formed in the vicinity of the first outer peripheral edge 321a.

The second rotating member 322 can rotate around the third rotating shaft 322a and the outer peripheral edge 322b of the second rotating member 322 (hereinafter referred to as the "second peripheral edge" And is rotatable in one direction due to the frictional force when the first rotating member 321 rotates by being positioned to be in contact with the outer peripheral end 321a. In addition, a second magnetic force member 322c may be formed in the vicinity of the second outer peripheral edge 322b.

The first magnetic member 321b and the second magnetic member 322c generate a force between the first rotating member 321 and the second rotating member 322 to rotate the first rotating member 321 and the second rotating member 322, (322) from falling off from each other.

Here, in the embodiment of the present invention, for example, a case where the first magnetic force member 321b and the second magnetic force member 322c are formed in the vicinity of the first outer peripheral edge 321a and the second outer peripheral edge 322b, respectively The first rotating member 321 and the second rotating member 322 themselves may be constituted by the first magnetic force member 321b and the second magnetic force member 322c, respectively.

On the other hand, when a force exceeding the friction force or attraction between the first rotating member 321 and the second rotating member 322 is applied to the shift lever 200, the first rotating member 321 and the second rotating member 322 The contact member 322d may be formed on at least one of the first peripheral edge 321a and the second peripheral edge 322a in the embodiment of the present invention. In the example, a case where the contact member 322d is formed on the second outer peripheral edge 322b will be described as an example.

The contact member 322d may be formed along the second peripheral edge 322b and the second peripheral edge 322b may be formed with an insertion groove 322e into which the contact member 322d can be inserted.

7, the second rotary member 322 may have an insertion groove 322e formed along the second outer peripheral edge 322b, and a contact member 322d having the shape of the second rotary member 322 may be formed. Can be inserted into the insertion groove 322e.

In the embodiment of the present invention, since the second rotary member 322 is circular, the contact member 322d can also be formed to have an O-ring shape. Further, in the embodiment of the present invention, a case where the contact member 322d is made of a rubber material for the purpose of increasing frictional force will be described as an example, but this is merely an example for facilitating understanding of the present invention, Various materials capable of increasing the frictional force between the first rotary member 321 and the second rotary member 322 can be used and the first outer peripheral edge of the first rotary member 321 321a may have a predetermined pattern (for example, a concave-convex shape or the like) on one side thereof, but the shape of the pattern may be variously changed.

In the embodiment of the present invention, the first rotating member 321 and the second rotating member 322 have different rotation ratios, the rotation ratio of the first rotating member 321 is P, 322 is represented by Q and P < Q, the following description will be given.

In other words, the second rotary member 322 rotates due to the rotation of the first rotary member 321. Since the rotation ratio of the second rotary member 322 is larger, the rotation amount of the second rotary member 322 is larger . As described above, in the embodiment of the present invention, the rotation ratios of the first rotating member 321 and the second rotating member 322 are made different from each other to detect the position of the shift lever 200 more precisely, Will be described later.

The sensing unit 323 is connected to the third rotary shaft 322a of the second rotary member 322 and rotates in one direction when the second rotary member 322 rotates and a plurality of slits 323a are formed along the outer circumference A slit 323b formed at regular intervals and a sensor 323c formed near the slit 323a to sense movement of the slit 323a as the slit 323b rotates.

In the embodiment of the present invention, the sensor 323c is an optical sensor including a light emitting portion 323d and a light receiving portion 323e formed on both outer sides of the slit portion 323b. The light emitting portion 323d and the light receiving portion 323e are formed on both sides of the slit portion 323b so that when the slit portion 323b rotates in accordance with the rotation of the second rotary member 322, So that the position of the shift lever 200 can be detected on the basis of the detected displacement.

In this embodiment, the rotation ratio of the second rotary member 322 is larger than that of the first rotary member 321. In this case, the amount of rotation of the first rotary member 321 The amount of rotation of the slit portion 323b that rotates about the third rotational axis 322a of the second rotational member 322 is larger than the rotational amount of the first rotational member 322 because the rotational amount of the second rotational member 322 is larger, &Lt; / RTI &gt;

Therefore, even if the rotation amount of the first rotary member 321 is small, the rotation amount of the slit portion 323b is relatively larger by the rotation ratios of the first rotary member 321 and the second rotary member 322, So that it is possible to more easily detect the minute movement of the shift lever 200.

That is, when the rotation ratios of the first rotating member 321 and the second rotating member 322 are the same, the rotation of the first rotating member 321 causes the slit 323b to rotate in the direction of the axis of rotation between the light emitting portion 323d and the light receiving portion 323e Passing through the slit portion 323b between the light emitting portion 323d and the light receiving portion 323e when the rotation ratio of the second rotary member 322 is larger than the number of the slits 323a passing through the slit portion 323a than the first rotary member 321 323a are increased, so that more accurate detection can be performed.

As described above, the vehicular transmission 1 according to the embodiment of the present invention includes at least two layers of shift patterns 400 arranged in the same direction so that the shift lever 200 can be moved in any one direction So that the structure for moving the shift lever 400 can be omitted. Therefore, the space required can be reduced, so that miniaturization can be advantageously achieved. In addition, by using the rotary members 321 and 322 having different rotation ratios, the movement of the shift lever 400 can be sensed to enable a finer sensing, and a slip phenomenon such as a backlash phenomenon can be detected by the contact member 322d It is possible to more precisely select the speed change stage.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the foregoing detailed description, and all changes or modifications derived from the meaning and scope of the claims and the equivalents thereof are included in the scope of the present invention Should be interpreted.
