3 is a control block diagram of a vehicle according to an exemplary embodiment.

A vehicle 1 according to an exemplary embodiment includes a shift command input unit 200 that receives a shift command for changing a shift range; a shift device 500 for changing a shift range according to a shift command; and a control unit 400 that deforms the surface of the shift command input unit 200 into a shape corresponding to the changed shift range. may include

The shift command input unit 200 may be provided to receive a shift command for selecting any one of a plurality of shift ranges. Here, the shift range may include a P range, an R range, an N range, and a D range, and may include only some of these, or may further include other shift ranges.

The shift command input unit 200 may be implemented in various shapes so that a shift command can be input. For example, the shift command input unit 200 may be implemented as a shift lever 210 capable of shifting a shift position corresponding to each of a plurality of shift ranges. In addition, the shift command input unit 200 may include a fixed upper surface and a side surface formed to surround the edge thereof, and may be implemented as a shift dial receiving a shift command input through rotation of the side surface.

Hereinafter, it will be described on the assumption that the shift command input unit 200 is implemented as the shift lever 210 .

4 is a perspective view of a shift command input unit according to an exemplary embodiment;

The shift command input unit 200 includes a shift lever 210 capable of moving between a plurality of shift positions; a knob 220 provided at one end of the shift lever 210; and a shift index 230 for guiding a shift position; and the like.

Referring to FIG. 4 , the shift lever 210 may be provided to be capable of linear reciprocating movement in the arrow direction and the y-axis direction. Shift positions corresponding to a plurality of shift ranges may be provided on a shift path on which the shift lever 210 moves. 4 exemplifies a case in which the R shift position corresponding to the R range, the N shift position corresponding to the N range, and the D shift position corresponding to the D range are sequentially provided on the shift path.

The knob 220 is provided at one end of the lever, and may be provided in a shape that can be easily gripped by a driver. The driver may move the lever connected to the knob 220 by holding the knob 220 and then moving it.

When the driver inputs a shift command by changing the shift position of the shift lever 210 , the shift device 500 may perform a shift operation to change the shift range according to the input shift command. If the driver moves the shift lever 210 from the N shift position to the D shift position, the shift device 500 may perform a shift operation to change the shift range from the N range to the D range.

Meanwhile, the shift index 230 may be provided adjacent to the shift position. The shift index 230 may indicate a shift range associated with an adjacent shift position. The driver may visually confirm this and move the shift lever 210 to change to a desired shift range.

In addition, the shift index 230 may guide the current shift position of the shift lever 210 . For example, when the shift lever 210 is positioned at the N shift position, the light provided inside the N shift index 230 may be turned on. The driver may recognize that the current shift range is the N range by visually checking the illumination of the shift index 230 .

In this case, since the driver must check the shift index 230 provided in the gearbox, the concentration of driving forward may be reduced. Accordingly, the vehicle 1 according to the disclosed embodiment may guide the driving range to the driver in a manner other than visual.

To this end, the shift command input unit 200 includes a shape transformation unit 300 that is deformed by a control signal; may further include. Here, the control signal may include an electrical signal or a heat conduction signal.

When the control signal is an electrical signal, the shape transformation unit 300 may be configured as an electrically variable element. For example, the shape change unit 300 may be implemented by an electro-active polymer (EAP). Here, the electrically activated polymer refers to a polymer capable of reproducibly exhibiting expansion, contraction, and bending phenomena when an external electrical stimulus is applied. Polymer/Metal Composite (IPMC), and conductive polymers containing carbon nanoparticles.

Alternatively, the shape changing unit 300 may be implemented with a piezoelectric material, ceramic, or the like that is deformed by electrical characteristics.

5 is a plan view and a side view of a shift command input unit including a shape change unit according to an embodiment, and FIG. 6 is a view for explaining various methods in which the shape change unit is deformed according to an embodiment.

Referring to FIGS. 5A and 5B , the outermost portion of the knob 220 of the shift command input unit 200 may be covered with a cover 221 . The driver may grip the knob 220 in close contact with the cover 221 .

The shape changing unit 300 may be provided to be in close contact with the inside of the cover 221 . Since the shape changing part 300 may have a predetermined thickness, the cover 221 may protrude in a shape corresponding to the shape changing part 300 . As a result, the driver may tactilely recognize the shape of the shape changing unit 300 through the surface of the cover 221 .

A plurality of shape transforming units 300 may be provided. In the case of FIG. 5 , a case in which the first shape transformation unit 300 and the second shape transformation unit 300 are provided in parallel in the x-axis direction is exemplified.

The control unit 400 may change the plurality of shape deformation units for transmitting the control signal according to the shift position of the shift lever 210 . For example, when the shift lever 210 is in the N shift position and is in the N range state, the controller 400 may not transmit a control signal to the first shape deforming unit and the second shape deforming unit. As a result, as shown in FIG. 5 , the shape-deformed portion may exist in a linear shape, which is a basic state.

The driver may recognize that the current shift range is the N range by tactically sensing two straight shapes on the surface of the cover 221 of the knob 220 .

Alternatively, when the shift lever 210 is moved from the N shift position to the R shift position, the shift device 500 may change the shift range to the R range. At the same time, the control unit 400 may deform the shape of the first shape-deformation part by transmitting a control signal only to the first shape-deformation part.

Referring to (a) of FIG. 6 , it can be confirmed that the upper shape-deformation part of the two shape-deformation parts is deformed into a wavy shape. The driver may recognize that the current shift range is the R range by tactically sensing the upper wavy shape and the lower straight shape on the surface of the cover 221 of the knob 220 .

Also, when the shift lever 210 is moved from the N shift position to the D shift position, the shift device 500 may change the shift range to the D range. At the same time, the control unit 400 may deform the shape of the second shape deformable part by transmitting a control signal only to the second shape deformable part.

Referring to (b) of FIG. 6 , it can be confirmed that the lower shape-deformation part of the two shape-deformation parts is deformed into a wavy shape. The driver may recognize that the current shift range is the R range by tactically sensing the upper straight shape and the lower wave shape on the surface of the cover 221 of the knob 220 .

In addition, when a shift command to another shift range is input, the control unit 400 may transmit a control signal to both of the shape change units 300 . As a result, both of the shape-deforming parts receiving the control signal may be deformed. Through this, the driver may tactilely sense two wave shapes on the surface of the cover 221 of the knob 220 and recognize the current shift range.

For this shape deformation, the knob 220 of the shift command input unit 200 includes a shape guide 250 on the inside; may further include.

7 is a cross-sectional view of a shift command input unit including a shape guide according to an exemplary embodiment.

The shape guide 250 may be provided as many as the number of shape-deformable parts to accommodate each of the plurality of shape-deformable parts.

Referring to FIGS. 7 (a) and (b), the shape guide 250 includes an accommodation space 251 capable of accommodating the deformed shape deformable part; and a guide partition wall 252 for guiding the shape of the deformed shape deforming part; may include

The accommodation space 251 may be provided with a space sufficient to accommodate not only the basic linear shape but also the deformed shape.

The guide partition wall 252 may be in close contact with the deformed shape-deformed part to maintain the shape of the shape-deformed part. As a result, the shape of the shape-deformed portion sensed through the cover 221 may be determined by the guide partition wall 252 .

So far, the case in which the shift command input unit 200 is implemented as the shift lever 210 has been exemplified. Alternatively, the shift command input unit 200 may be implemented as a shift dial.

Specifically, the shift command input unit 200 includes a fixed upper surface; and a side formed to surround the periphery of the upper surface and rotatable along the periphery of the upper surface; It may be implemented as a shift dial comprising a.

The shift dial may receive a shift command by rotating the side. That is, the driver needs to touch the upper surface and/or the side surface of the shift dial to input a shift command.

Accordingly, the shift dial may include a plurality of shape-deforming portions provided on at least one of an upper surface and a side surface. Here, since the shape-modifying portion provided on the speed change dial is the same as described with reference to FIGS. 3 to 7 , a detailed description thereof will be omitted.

Even when the shift command input unit 200 is implemented as a shift dial, the driver may recognize the current shift range by tactically sensing a shape deformable part provided on the surface of the shift dial.

8 is a flowchart of a vehicle control method according to an exemplary embodiment.

First, the vehicle 1 may check whether a shift command is input. (800) Specifically, the shift command input unit 200 of the vehicle 1 may check whether a shift command for changing a shift range is input. If the shift command is not input, the vehicle 1 may repeatedly check this.

On the other hand, if a shift command is input, the vehicle 1 may change the shift range according to the input shift command ( 810 ). Specifically, the shift device 500 of the vehicle 1 has a shift range corresponding to the shift command. to perform a shift operation.

Finally, the vehicle 1 may deform the surface of the shift command input unit 200 into a shape corresponding to the changed shift range ( 820 ). Specifically, the controller 400 of the vehicle 1 corresponds to the shift range. A control signal may be transmitted to the shape deforming unit to transform the shape deforming part provided on the surface of the shift command input unit 200 into a shape that is changed.

As a result, the driver can recognize the current shift range of the vehicle 1 only by touch.
