Description

[0001] Automotive transmission [0002]

[0001] The present invention relates to a vehicular transmission, and more particularly, to a shift control device for a vehicle, which is provided with an operation feeling in accordance with an improvement in thrust during a shift to a D (forward) The speed change can be smoothly performed.

Generally, a transmission of a vehicle has a gear ratio different in order to keep the rotation of the engine constant in accordance with the speed of the vehicle. In order to change the gear ratio of the transmission, the shift lever .

At this time, the driver can change the gear ratio by selecting the speed change stage by operating the shift lever positioned next to the driver's seat.

The transmission is divided into a manual transmission and an automatic transmission.

The manual transmission is a shift device that directly selects the gear positions of the first, second, third, and fourth stages in accordance with the traveling speed of the vehicle. The automatic transmission includes a traveling speed of the vehicle, an engine load, The ECU of the vehicle automatically adjusts the speed change stage according to the opening amount and the like.

The automatic transmission generally includes a P stage used for driving a vehicle at an emergency, an D stage used for advancing the vehicle, an R stage used for backing the vehicle, and an N stage for blocking the output of the engine from being transmitted to the drive wheel And a speed change stage.

The driver can select each gear range using the shift lever. There are two types of shift lever, lever type and dial type. In addition, there are some vehicles with each speed range button type.

A common lever type is configured such that the speed change stages are arranged in the order of P-R-N-D, and the lever is moved in a linear direction to select each gear change stage. In recent years, as the lever type, the position of the gear position of the PRND is not fixed, and the lever is configured to return after being tilted in place in accordance with the operation of the driver, so that the gear position can be selected in such a manner that the PRND changes sequentially in accordance with the tilting direction of the lever A speed change device is provided.

On the other hand, the dial type is configured such that the speed change stage of the P-R-N-D is positioned in the vicinity of the dial rotating within a certain angle range and the shift stage is selected by positioning a specific point of the dial at each speed change stage of the P-R-N-D.

The transmission equipped with the lever type or dial type shift lever tactilely transmits the throttle opening so that when the driver selects the transmission side of the PRND, the change of the speed change stage and the shift lever are located at the respective speed change stages do. In order to realize such a thief feeling, a detent device is provided in the transmission. However, a conventional design has required a complicated structure because it realizes a thief feeling using a mechanical structure.

Further, in order to stably drive the vehicle, when changing the speed change stage from the D-stage to the P-stage or R-stage, or vice versa, the change from the P-stage or R-stage to the D-stage should be made only in a state where the vehicle is almost stationary. To this end, the conventional transmission is provided with a separate blocking device that allows the change of the speed change stage only when a predetermined condition is satisfied, and prevents the shift lever from being shifted as described above.

Therefore, when the driver operates the shift lever 10 to change the speed change stage, the variable unit of the linear drive motor 80 is moved reciprocally with respect to the fixed unit, as shown in Figs. 6A to 6C The speed change stage is changed.

7 is a configuration diagram showing a vehicular transmission according to an embodiment of the present invention.

As shown in the drawing, the vehicular transmission (100) according to the embodiment of the present invention includes a first pattern unit (110) capable of maintaining the N mode or the R mode as the shift lever (10) And a second pattern unit 130 capable of maintaining an N mode or a D mode as the shift lever 10 of the transmission is moved and positioned.

Here, the first pattern unit 110 and the second pattern unit 130 are positioned vertically or horizontally adjacent to each other, and the shift lever 10 can be selectively moved and positioned.

The transmission for a vehicle 100 according to the embodiment of the present invention is disposed adjacent to the first pattern unit 110 and is configured such that after the shift lever 10 is tilted from the first pattern unit 110 And an R-stage tilting unit 120 that is returned to the first pattern unit 110.

The transmission for a vehicle 100 according to an embodiment of the present invention is disposed adjacent to the second pattern unit 130 and after the shift lever 10 is tilted from the second pattern unit 130, 2 pattern unit 130. The D-tilting unit 140 may include a D-tilting unit 140 and a D-

The R-tilting portion 120 is disposed on the opposite side of the first pattern portion 110 from the second pattern portion 130, and the D-tilting portion 140 is disposed on the opposite side of the second pattern portion 130 from the center of the second pattern portion 130 May be disposed on the opposite side of the first pattern unit 110.

In order to support the embodiment of the present invention, the R-tilting unit 120, the first pattern unit 110, the second pattern unit 130, and the D-tilting unit 140 are sequentially arranged Are shown as an example, they can be arranged in the reverse order.

In order to support the embodiment of the present invention, the R-tilting unit 120, the first pattern unit 110, the second pattern unit 130, and the D-tilting unit 140 are arranged in the longitudinal direction But it may be arranged in the lateral direction.

On the other hand, the vehicular transmission (100) according to the embodiment of the present invention may include a P-stage switch (200) for switching from N mode to P mode by switch operation.

A process of shifting by the vehicle transmission 100 having the above-described structure will be described below.

FIGS. 8 to 16 are diagrams sequentially illustrating a shift process performed by the vehicular transmission according to the embodiment of the present invention.

8 is a diagram showing a state in which the shift lever is located in the first pattern portion and the P-stage switch is operated to be in the P-mode.

Such a state is a state in which the vehicle is parked or stopped. In this state, when the driver wishes to drive the vehicle, the P-stage switch 200 may be released to become the N-mode as shown in FIG.

That is, when the P-stage switch 200 is released in the P mode, the shift to the N mode is performed as shown in FIG. 9. In this state, the driver moves the shift lever 10, The R mode or the D mode can be selected.

10 is a view showing a process in which the driver selects the R mode by operating the shift lever in the N mode.

As shown in the figure, when the R mode is selected to move the vehicle backward, the driver tilts the shift lever 10 to the R-tilting portion 120, 110 to the R-tilting portion 120, and then returns to the first pattern portion 110 to be shifted to the R-mode.

Therefore, the driver can drive the vehicle in the R mode and can move it backward.

On the other hand, when the vehicle is shifted to the D mode for running the vehicle forward after advancing backward in the R mode, the shift lever 10 is operated to shift to the second pattern portion 130 And then tilted to the D-tilting unit 140 continuously.

At this time, as the shift lever 10 moves from the first pattern unit 110 to the second pattern unit 130, the speed change stage of the vehicle is shifted from the R mode to the N mode, and the D-tilting unit 140, then returns to the second pattern unit 130 and shifts to the D mode.

Therefore, the shift from the R mode to the D mode is performed after passing through the N mode.

9, the shift lever 10 may be positioned in the first pattern unit 110 to shift from the N mode to the D mode. In this case, as shown in FIG. 11, The shift lever 10 may be operated to move to the second pattern unit 130 and then tilted to the D-tilting unit 140.

At this time, when the shift lever 10 moves from the first pattern unit 110 to the second pattern unit 130, the shift lever 10 continues to maintain the N mode, and is continuously tilted to the D-tilting unit 140, And then returns to the second pattern unit 130, the shift to the D mode is performed.

As shown in Fig. 11, when the shift lever 10 is located in the second pattern unit 130 and is in the D mode, when it is desired to stop the running of the vehicle and convert to the P mode in order to drive the vehicle, As shown in the figure, the shift lever 10 is moved to the first pattern unit 110 to shift to the N mode, and then the P-stage switch 200 is operated as shown in FIG.

When the P-step switch 200 is operated in a state where the shift lever 10 is positioned on the first pattern unit 110 and the vehicle is to be driven again after the vehicle is parked, the shift lever 10) to select R mode, N mode and D mode.

13 and 14 illustrate the P mode and the N mode in a state where the shift lever 10 is positioned on the second pattern unit 130. As shown in FIG.

The first pattern unit 110 can maintain the NR mode as the shift lever 10 is positioned and the second pattern unit 130 can maintain the ND mode as the shift lever 10 is positioned The shift lever 10 may be maintained in the P mode and the N mode in a state where the shift lever 10 is positioned on the second pattern unit 130. [

For example, as shown in FIG. 10, when the shift lever 10 is located in the first pattern unit 110 and is in the R mode, when it is desired to stop the running of the vehicle and convert it to the P mode , The shift lever 10 is shifted from the first pattern unit 110 to the second pattern unit 130 so as to shift to the N mode, as shown in FIG. 14, The switch 200 is operated to set the P mode.

Therefore, the vehicle transmission 100 according to the embodiment of the present invention can maintain the N mode and the P mode even in a state where the shift lever 10 is positioned on the second pattern unit 130.

As shown in Fig. 13, the process of shifting the transmission for driving the vehicle while the vehicle is in the P mode with the shift lever 10 positioned on the second pattern portion 130 is shown in Figs. 14 16.

First, when the P-step switch 200 is released to travel the vehicle, the shift lever 10 is maintained in the N mode with the shift lever 10 positioned on the second pattern unit 130 as shown in FIG.

That is, when the P-step switch 200 is released in the P mode, the shift is made to the N mode as shown in FIG. 14. In this state, the driver moves the shift lever 10, The R mode or the D mode can be selected.

15 is a view showing a process in which the driver selects the R mode by the operation of the shift lever 10 in the N mode.

As shown in the figure, when the vehicle is shifted to the R mode to travel backward, the shift lever 10 is operated to move to the first pattern unit 110, and then, the R-tilting unit 120 Tilting.

At this time, as the shift lever 10 moves from the second pattern portion 130 to the first pattern portion 110, the gear position of the vehicle continues to maintain the N-mode, and the R-tilting portion 120 continuously moves, And then returns to the first pattern unit 110, the shift to the R mode is performed.

Therefore, when the driver is able to drive the vehicle in the R mode and move backward, and thereafter shifts to the D mode to drive the vehicle forward, the shift lever 10 is operated as described above, And then tilted to the D-tilting portion 140 successively.

At this time, as the shift lever 10 moves from the first pattern unit 110 to the second pattern unit 130, the speed change stage of the vehicle is shifted from the R mode to the N mode, and the D-tilting unit 140, then returns to the second pattern unit 130 and shifts to the D mode, so that the shift from the R mode to the D mode is performed after passing through the N mode (see FIG. 11).

On the other hand, FIG. 16 is a view showing a process of the driver selecting the D mode by the operation of the shift lever 10 in the N mode.

As shown in the figure, the shift lever 10 may be positioned in the second pattern unit 130 to be shifted from the N mode to the D mode. In this case, the driver may shift the shift lever 10 to the D- The shift lever 10 is tilted from the second pattern unit 130 to the D-tilting unit 140, and then the shift lever 10 is returned to the D-tilting unit 140 and shifted to the D mode.

Therefore, the driver can drive the vehicle in the D mode and advance it.

15, when the shift lever 10 is located in the first pattern unit 110 and is in the R mode, the vehicle is shifted to the P-mode in order to shift the vehicle to the P-mode, as shown in FIG. 14 The shift lever 10 is shifted from the first pattern unit 110 to the second pattern unit 130 so as to shift to the N mode. Then, as shown in FIG. 13, the P-stage switch 200 is operated You.

In the case where the shift lever 10 is located in the second pattern unit 130 as shown in Fig. 16 and the vehicle is shifted to the P mode in the state of being in the D mode, The shift lever 10 is moved to the first pattern unit 110 so that the shift is made to the N mode, and then the P-stage switch 200 is operated as shown in FIG.

As described above, when the shift lever 10 is positioned on the first pattern unit 110, the vehicle may be in the N mode or the R mode. When the shift lever 10 is in the second pattern unit 130 The vehicle may be in the N mode or the D mode.

At this time, when the shift lever 10 is positioned in the first pattern unit 110 and moves to the second pattern unit 130 in the N mode or the R mode, the N mode is maintained or the shift to the N mode is performed When the shift lever 10 is positioned in the second pattern unit 130 and moves to the first pattern unit 110 in the N mode or the D mode, the N mode is maintained or the shift mode is changed to the N mode .

Therefore, the section in which the shift lever 10 moves from the first pattern unit 110 to the second pattern unit 130 or from the second pattern unit 130 to the first pattern unit 110 is the R mode D mode, or shifted from the D mode to the R mode, and shifting to the N mode.

Alternatively, it may be a period for maintaining the N mode in the N mode.

The section in which the shift lever 10 moves from the first pattern unit 110 to the second pattern unit 130 or from the second pattern unit 130 to the first pattern unit 110 is a mode in which the R mode And the N th mode is maintained in the N mode. Thus, the thrust is maintained constant as shown in Fig. 17, so that the driver can feel the smooth operation feeling .

17 is a graph showing a change in thrust force in each section in which shifting is performed by the vehicular transmission device 100 according to the embodiment of the present invention.

As shown in the figure, the period in which the shift from the R mode to the N mode or the D mode to the N mode or the N mode is maintained in the N mode is not a period in which the vehicle is shifted forward or backward, So that the driver can feel a smooth operation feeling in shifting.

That is, the period in which the shift from the R mode to the N mode, the D mode to the N mode, or the N mode is maintained is achieved when the shift lever 10 moves from the first pattern portion 110 to the second pattern portion 130, The magnet 820 and the coil 860 of the linear driving motor 80 move from the second pattern unit 130 to the first pattern unit 110. In this case, The magnetic flux density of the magnet 820 and the coil 860 is moved in a section where the magnetic flux density is high.

The width of the thrust change in the section in which the shift lever 10 moves from the first pattern unit 110 to the second pattern unit 130 or the second pattern unit 130 to the first pattern unit 110 is small So that the driver can feel a smooth operation feeling.

The section in which the shift lever 10 moves from the first pattern unit 110 to the R-tilting unit 120 or from the second pattern unit 130 to the D-tilting unit 140 is the R mode, or a shift from N mode to D mode.

When the shift lever 10 is moved from the first pattern unit 110 to the R-tilting unit 120, the linear drive motor 80 is driven to move the variable unit to the fixed unit 110, as shown in FIG. 6B or 6C. The magnet 820 and the coil 860 are not overlapped or completely overlapped with each other so that the magnetic flux density of the magnet 820 and the coil 860 is low .

Therefore, when the shift from the N mode to the R mode is performed, the magnetic flux density of the magnet 820 and the coil 860 of the linear drive motor 80 becomes high and low, whereby the thrust becomes small, So that the driver feels a sense of throttling during shifting and is provided with a sense of operation that allows the shift to be recognized.

When the shift lever 10 is moved from the second pattern unit 130 to the D-tilting unit 140, the linear drive motor 80 is driven to rotate the variable unit as shown in FIG. 6B or 6C. The magnet 820 and the coil 860 are not overlapped or completely overlapped with each other so that the magnetic flux of the magnet 820 and the coil 860 The density is lowered.

Therefore, when the shift from the N mode to the D mode is performed, the magnetic flux density between the magnet 820 and the coil 860 of the linear drive motor 80 becomes high and low, whereby the thrust becomes small, So that the driver feels a sense of throttling during shifting and is provided with a sense of operation that allows the shift to be recognized

 Thus, as shown in Fig. 17, the shift range from the N-th stage to the R-stage or from the N-th stage to the D-th stage increases the variation range of the thrust force and provides the driver with a sense of throttling during shifting, So that it is possible to provide a sense of operation.

In other words, since the section in which the shift from the N mode to the R mode and the shift from the N mode to the D mode is performed is for shifting the vehicle forward or backward, the change width of the thrust is large, So that it is possible to provide a sense of operation that can recognize that the shift is performed.

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 detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.

Wherein the first pattern portion and the second pattern portion are located adjacent to each other so that the shift lever can be selectively moved and positioned. 3. The method of claim 2,
Wherein the R-tilting portion is disposed on a side opposite to the second pattern portion with respect to the first pattern portion,
Wherein the D-tilting portion is disposed on the opposite side of the first pattern portion with respect to the second pattern portion. The method according to claim 1,
Wherein the R-tilting portion, the first pattern portion, the second pattern portion, and the D-tilting portion are arranged in a row direction. The method according to any one of claims 1 to 4,
And a P-step switch for switching to a P mode by a switch operation. The method according to claim 1,
And a linear drive motor that moves the shift lever or provides a reaction force to a force by which the driver operates the shift lever,
The linear drive motor includes:
A fixed unit;
A variable unit movably installed with respect to the fixed unit;
A coil provided in any one of the fixed unit and the variable unit, and a magnet provided in the other unit. The method according to claim 6,
When the shift lever is moved from the second pattern portion or the second pattern portion to the first pattern portion in the first pattern portion,
And the variation width of the thrust is reduced as the magnetic flux density of the magnet and the coil moves. The method according to claim 6,
When the shift lever is tilted from the first pattern portion to the R-tilting portion or tilted from the second pattern portion to the D-tilting portion,
Wherein the magnetic flux density of the magnet and the coil is shifted to a low region in a high magnetic flux density region, and the first pattern portion and the second pattern portion are shifted from each other, gearbox.
