Description

Technical Field

[0001] The present invention relates to the technical field of vehicle shifting, and in particular to a vehicle shifting device and a shifting method. Background Art

[0002] Electronic shifter (E-Shifter) controls the gear position of the transmission electronically rather than mechanically, and is currently widely used in vehicles. The driver can shift gears among Park (P), Neutral (N), Reverse (R) and Drive (D) simply by operating the electronic shifter.

[0003] Current electronic shift devices include a joystick type using a joystick, a button type using a button, and a dial type using a dial. In a conventional dial type electronic shift device, when the shift dial is rotated one position clockwise from the middle (Null) position to the driving gear side null (Nd) position, the gear is shifted to the N gear, and when the shift dial is further rotated one position clockwise in the Nd position, the gear is shifted to the D gear. When the shift dial is rotated one position counterclockwise from the Null position to the reverse gear side null (Nr) position, the gear is shifted to the N gear, and when the shift dial is further rotated one position counterclockwise from the Nr position, the gear is shifted to the R gear. When the operation is removed after the shift dial is operated, the shift dial can be returned to the Null position from the D gear, the Nd position, the R gear, or the Nr position. The return of the shift dial can be achieved by an elastic member. When the driver rotates the shift dial, the presence of the elastic member will also give the driver a sense of operation, that is, the driver can feel the force of the shift dial trying to return to the Null position when rotating the shift dial. Since the rotation amount when shifting to D gear (or R gear) is greater than the rotation amount when shifting to N gear, the driver can always feel a small sense of operation when shifting to N gear, which makes the driver feel that the shift position is unclear and easily causes the driver to make erroneous operations.

[0004] The above description of the background technology is only for facilitating an in-depth understanding of the technical solution of the present invention (such as the technical means used, the technical problems solved and the technical effects produced), and should not be regarded as an admission or any form of implication that the information constitutes prior art already known to those skilled in the art.

[0046] The implementation scheme of the present invention is described in detail below. This implementation scheme is implemented on the premise of the technical scheme of the present invention, and a detailed implementation method and specific operation process are given, but the protection scope of the present invention is not limited to the implementation scheme described below.

[0047] Figure 1 is a schematic diagram showing a shifting device of a vehicle according to an embodiment of the present invention. Figure 2 is a top view of a gear shifting device for a vehicle according to an embodiment of the present invention. Figure 3 is along Figure 2 A cross-sectional view taken along line AA in FIG. Figure 4 is along Figure 2 A cross-sectional view taken along line BB in FIG. Figure 5 is an exploded view of a gear shifting device for a vehicle according to an embodiment of the present invention.

[0048] Reference Figures 1 to 5 , the shift device according to the embodiment of the present invention includes a rotating component 100 and a stationary component 200. The rotating component 100 can rotate around an axis J under an external rotation operation. The stationary component 200 is disposed inside the rotating component 100 around the axis J and supports the rotating component 100 to be rotatable.

[0049] The axis J may be an imaginary straight line along the up-down direction. In this document, the up-down direction does not represent the positional relationship and direction when assembled to an actual device, and in this document, the direction coincident with or parallel to the axis J is referred to as the "axial direction", the radial direction centered on the axis J is referred to as the "radial direction", and the circumferential direction of a circle centered on the axis J is referred to as the "circumferential direction".

[0050] Figure 6 is a schematic diagram of a stationary component according to an embodiment of the present invention. Figures 3 to 6 The stationary component 200 includes a fixed shaft 210. The fixed shaft 210 is arranged along the axis J with the axis J as the center.

[0051] Figure 7 is a schematic diagram of a rotating component according to an embodiment of the present invention. Figures 3 to 7 The rotating component 100 includes a selection button 110 , a connecting cylinder 120 and an outer ring 130 .

[0052] The selection button 110 can receive an external rotational operating force. A circular hole is formed in the center of the selection button 110. Since the selection button 110 is a component operated by the driver, the cross section of the outer surface of the selection button 110 can be polygonal instead of circular to prevent the driver's finger from slipping when operating the selection button 110, and the edge between two adjacent surfaces of the outer surface of the selection button 110 can be formed into a rounded structure 111.

[0053] The connecting cylinder 120 includes an upper cylinder portion 121 and a lower cylinder portion 122 connected together and communicating with each other. Each of the upper cylinder portion 121 and the lower cylinder portion 122 may be in a substantially cylindrical shape. The upper cylinder portion 121 is connected to the selection button 110 through a spline structure. Specifically, an outer spline 123 is formed on the outer circumferential surface of the upper cylinder portion 121, and an inner spline 112 is formed on the inner circumferential surface of the selection button 110. The outer spline 123 of the upper cylinder portion 121 is engaged with the inner spline 112 of the selection button 110. A plurality of connecting holes 124 may be formed in the circumferential direction at the lower portion of the lower cylinder portion 122, and a plurality of connecting protrusions 131 corresponding to the connecting holes 124 may be formed at the upper portion of the outer ring 130. The connecting protrusions 131 can be inserted into the connecting holes 124, so that the connecting cylinder 120 and the outer ring 130 are fixed together by the engagement of the connecting holes 124 and the connecting protrusions 131. Therefore, when the selector button 110 is rotated by receiving a rotation operation from the outside, both the connection cylinder 120 and the outer ring 130 can rotate integrally with the selector button 110 .

[0054] Figure 8 Schematic diagram of a rotating component and a stationary component according to an embodiment of the present invention. Figures 3 to 8 , the selection button 110, the connection cylinder 120 and the outer ring 130 are arranged on the fixed shaft 210 along the axial direction of the fixed shaft 210 and in the order of the selection button 110, the connection cylinder 120 and the outer ring 130 with the axis J as the center. That is, the selection button 110 is arranged on one side (specifically, the upper part) of the axial direction of the fixed shaft 210, and the outer ring 130 is arranged on the other side (specifically, the lower part) of the axial direction of the fixed shaft 210. The outer peripheral surface of the fixed shaft 210 extends radially outward to form a flange portion 211, and the upper end surface of the flange portion 211 can contact the inner surface of the upper part of the lower cylinder portion 122, thereby supporting the connection cylinder 130. That is, the fixed shaft 210 included in the stationary component 200 can support the rotating component 100 and allow the rotating component 100 to rotate freely. In the process of installing the rotating component 100 from top to bottom on the fixed shaft 210, the flange portion 211 can determine the installation position of the rotating component 100.

[0055] As described above, the rotating member 100 may be disposed on the fixed shaft 210 disposed centered on the axis J, and may rotate relative to the fixed shaft 210 under an external rotation operation. Figure 4 and Figure 7 , the gear shifting device of the vehicle may further include a rotation retaining member 160 . Fig. 9 yes Figure 7 A top view of the rotating and stationary parts is shown. Figure 4 and Fig. 9As shown, the rotation retainer 160 is disposed around the outer ring 130. Since the outer ring 130 can be rotatably supported by the rotation retainer 160, the rotation center of the outer ring 130 does not deviate from the axis J, thereby stabilizing the rotation of the outer ring 130. At least two rotation retainers 160 may be provided. Figures 3 to 6 The shift device of the vehicle may include an upper box body 310 and a lower box body 320 that are combined with each other, and the rotation retainer 160 may be disposed on the lower box body 320 , for example, by a screw 161 .

[0056] In addition, the fixing shaft 210 may be disposed on the lower box body 320. A mounting hole 311 is formed on the upper box body 310, and the upper barrel 121 is configured to pass through the mounting hole 311 of the upper box body 310. Therefore, the lower barrel 122 and the outer ring 130 are both disposed in the accommodation space formed by the upper box body 310 and the lower box body 320, and the selection button 110 connected to the upper barrel 121 is located outside the accommodation space for the driver to operate.

[0057] Similar to a conventional dial-type electronic shifting device, the driver can select the vehicle's neutral (Neutral, N), reverse (Reverse, R) or drive (Drive, D) gear by rotating the selector button 110. Unlike a conventional dial-type electronic shifting device, in a conventional dial-type electronic shifting device, operating positions corresponding to the N, R and D gears are respectively set on the rotation path of the shift dial, and the driver switches gears by rotating the shift dial from the neutral (Null) position to the corresponding operating position.

[0058] In the shifting device of the vehicle according to the embodiment of the present invention, the rotating component 100 can rotate around its own axis J between multiple angular positions and can be maintained at a corresponding angular position, and the rotating component 100 can rotate from one angular position to another angular position in one rotation operation. The shifting device further includes a detection component and a controller. The detection component can detect the rotation direction of the rotating component 100. The controller determines the gear to be switched after one rotation operation according to the current gear position of the vehicle and the rotation direction of the rotating component.

[0059] When the gear position of the vehicle is currently in R gear, D gear or P gear, when the rotating component 100 rotates from one angular position along the first rotation direction or the second rotation direction to another angular position, the controller can determine that the gear position to be switched is N gear. When the gear position of the vehicle is currently in N gear, when the rotating component 100 rotates from one angular position along the first rotation direction to another angular position, the controller can determine that the gear position to be switched is D gear. When the gear position of the vehicle is currently in N gear, when the rotating component 100 rotates from one angular position along the second rotation direction to another angular position, the controller can determine that the gear position to be switched is R gear. Specifically, the first rotation direction may be clockwise, and the second rotation direction may be counterclockwise.

[0060] Therefore, compared with the conventional electronic shifting device of the dial type, the shifting device according to the embodiment of the present invention does not set the Null position and the operating positions corresponding to the N gear, the R gear and the D gear, nor does it have a return component for returning the rotating component 100 to the Null position. The rotating component 100 of the shifting device is always in a stable state of being maintained at one of the angular positions before and after the shifting, and the operation feeling felt by the driver is the same and clear regardless of shifting to the D gear or the R gear or shifting to the N gear. In addition, the driver does not need to rotate the rotating component 100 to a specific angle, but only needs to control the direction of rotation of the rotating component 100 to perform the shifting operation, which is simple and convenient to operate.

[0061] Hereinafter, it will be described in detail that the rotating component 100 can rotate between a plurality of angular positions and can be maintained at a corresponding one of the angular positions and that the detecting component can detect the rotating direction of the rotating component 100 .

[0062] Fig.10 is a top view of the outer ring according to an embodiment of the present invention. Fig.10 As shown, a plurality of valleys 140 and peaks 150 between adjacent valleys 140 are formed on the inner surface of the outer ring 130 in the rotating component 100 in the circumferential direction.

[0063] Re-reference Figures 3 to 6, the stationary component 200 includes a positioning member 220. In one example, the positioning member 220 can be radially connected to the fixed shaft 210. In this embodiment, the stationary component 200 can further include an inner ring 230, and the positioning member 220 can be connected to the fixed shaft 210 through the inner ring 230. The inner ring 230 is arranged on the fixed shaft 210 with the axis J as the center. The inner ring 230 can be arranged on the fixed shaft 210 through a spline structure. Specifically, the outer peripheral surface of the fixed shaft 210 in the other axial direction (specifically, the lower part) forms an outer spline 212, and the inner peripheral surface of the inner ring 230 forms an inner spline 231. The inner spline 231 of the inner ring 230 is meshed with the outer spline 212 of the fixed shaft 210. In addition, the inner ring 230 has a receiving hole 232 extending in the radial direction, and the positioning member 220 is arranged in the receiving hole 232.

[0064] In one example, two receiving holes 232 may be formed, and there are also two positioning members 220 , and the two positioning members 220 are respectively disposed in corresponding receiving holes 232 .

[0065] Fig.11 Schematic diagram of the structure between the positioning member and the outer ring according to an embodiment of the present invention. Fig.11 As shown, the positioning member 220 can be inserted into any one of the plurality of valleys 140, so that the rotating component 100 can be maintained at one of the plurality of angular positions, and under the action of one rotation operation, the positioning member 220 can be inserted from one valley 140 across the peak 150 to another adjacent valley 140. In the case of two positioning members 220, the two positioning members 220 are inserted into the valleys 140 arranged symmetrically to each other.

[0066] Reference Figures 3 to 6 as well as Fig.11 The positioning member 220 may include a telescopic contact head 240 and an elastic member 250. The telescopic contact head 240 is disposed in the receiving hole 232, and the head of the telescopic contact head 240 can extend from the receiving hole 232. The elastic member 250 is disposed in the receiving hole 232 to elastically support the telescopic contact head 240. Specifically, the elastic member 250 may be a spring.

[0067] FIG. 12A to FIG. 12E Schematic diagram showing the position change of the positioning member and the outer ring in one rotation operation according to an embodiment of the present invention. FIG. 12A to FIG. 12C, the first telescopic contact head 241 is inserted into the first valley portion 141 of the outer ring 130, and the second telescopic contact head 242 is inserted into the fifth valley portion 145 of the outer ring 130. In one clockwise rotation operation, the first telescopic contact head 241 can be inserted from the first valley portion 141 across the peak portion 150 to the second valley portion 142, and the second telescopic contact head 242 can be inserted from the fifth valley portion 145 across the peak portion 150 to the sixth valley portion 146. Fig. 12A , Fig.12D and Fig.12E In one counterclockwise rotation operation, the first telescopic contact head 241 can be inserted from the first valley portion 141 across the peak portion 150 to the eighth valley portion 148 , and the second telescopic contact head 241 can be inserted from the fifth valley portion 145 across the peak portion 150 to the fourth valley portion 144 .

[0068] In addition, during the above process, the driver can feel a clear sense of operation, that is, the driver can feel the elastic force of the elastic member 250 in a compressed state when the positioning member 220 reaches the peak 150 and the release of the above elastic force when the positioning member 220 reaches the valley 140.

[0069] Re-reference Fig.10 , eight valleys 140 can be formed at a 45° interval, and eight peaks 150 are arranged between the valleys 140, so the angle α between the symmetry axes of two adjacent valleys 140 (or two adjacent peaks 150) is 45°. As described above, the rotation of the rotating component 100 is achieved by the driver operating the selector knob 110 to rotate. Fig.13 is a top view of a selection button according to an embodiment of the present invention. Fig.13 As shown, the cross section of the selection button 110 may be an octagon, so that the angle β of the line connecting two adjacent vertices of the octagon and its center is 45°. Under a rotation operation by the driver, the selection button 110 rotates and drives the outer ring 130 and the selection button 110 to rotate integrally, and the positioning member 220 crosses the peak 150 from one valley 140 and is inserted into another adjacent valley 140. Since the angle of the line connecting two adjacent vertices of the selection button 110 and its center is also equal to 45°, the selection button 110 can be rotated 45° from one angular position to another angular position, and the appearance of the selection button 110 before and after the rotation does not change.

[0070] However, α and β of the present invention are not limited thereto, and α and β may also be 36° or 60°, etc., thereby, the cross section of the selection button 110 may be a decagon, a hexagon, etc.

[0071] Fig.14 Schematic diagram of the structure of the detection component according to the embodiment of the present invention. Fig.14As shown, the detection component may include a plurality of sensor trigger elements 410, a sensor 420 and a detection unit. The plurality of sensor trigger elements 410 are uniformly arranged along the circumferential direction on the bottom surface of the rotating component 100 (specifically, the outer ring 130), and each of the plurality of sensor trigger elements 410 is inclined at a predetermined angle (θ) relative to the bottom surface of the rotating component 100 (specifically, the outer ring 130). The sensing surface of the sensor 420 is arranged to be parallel to the bottom surface of the rotating component 100 (specifically, the outer ring 130). Therefore, each of the plurality of sensor trigger elements 410 is also inclined at an angle θ relative to the sensor 420. Therefore, as the rotating component 100 rotates, the sensor 420 can sense that the distance between the sensor trigger element 410 changes. The detection unit determines the rotation direction of the rotating component 100 based on the distance change between the sensor 410 and the sensor trigger element 410 sensed by the sensor 410.

[0072] Fig.15 is a schematic diagram of a plurality of sensor triggering elements according to an embodiment of the present invention. Since the rotating component 100 rotates at an angle α in one rotation operation, the positioning member moves from one valley 140 to another adjacent valley 140. Therefore, in order to detect the rotation direction of the rotating component 100 in one rotation operation, as shown in FIG. Fig.15 As shown, the sensor trigger elements 410 are configured to be equal in number to the valleys 140 , that is, the sensor trigger elements 410 are configured at the same angle α, and when the positioning member 220 is inserted into any one of the plurality of valleys 140 , the sensor 420 is disposed opposite to one of the sensor trigger elements 410 .

[0073] FIG. 16A to FIG. 16E is a schematic diagram showing the position change between the sensor and the sensor trigger element under one rotation operation according to an embodiment of the present invention. Since the angle between two adjacent sensor trigger elements 410 is also equal to the angle α. As described above, under one rotation operation, the rotating component 100 rotates by an angle α, and the positioning member 220 can be inserted from one valley 140 across the peak 150 to another adjacent valley 140. Therefore, for the sensor trigger element 410, when the rotating component 100 rotates by an angle α, the sensor trigger element 410 (for example, the first sensor trigger element 411) disposed opposite to the sensor 420 will move away from the sensor 420, and another adjacent sensor trigger element 410 (for example, the second sensor trigger element 412) will move to a position opposite to the sensor 420.

[0074] like Fig.16AAs shown, the first sensor trigger element 411 is opposite to the sensor 420, specifically, located above the sensor 420. The sensor 420 can sense the distance between the first sensor trigger element 411. For example, the distance can be the distance from the center point of the sensing surface of the sensor 420 to the sensor trigger element 410 along the axial direction. Fig.16A In the embodiment, the sensor 420 can sense that the distance between the sensor 420 and the first sensor triggering element 411 is d1.

[0075] When the outer ring 130 rotates clockwise, the first sensor triggering element 411 gradually moves away from the sensor 420. Fig. 16B As shown, the sensor 420 can sense that the distance between the sensor 420 and the first sensor triggering element 411 becomes d2, and d2 is smaller than d1. Therefore, the sensor 420 can sense that the distance between the sensor 420 and the sensor triggering element 410 is reduced.

[0076] Furthermore, if Fig. 16C As shown, the sensor 420 not only cannot sense the first sensor triggering element 411 , but also cannot sense any other sensor triggering element 410 .

[0077] As the outer ring 130 rotates, the second sensor triggering element 412 gradually approaches the sensor 420. Fig.16D As shown, the second sensor triggering element 412 enters the sensing range of the sensor 420 , and the sensor 420 can sense that the distance between itself and the second sensor triggering element 412 is d3 .

[0078] As the second sensor triggering element 412 approaches further, Fig.16E As shown, the sensor 420 can sense that the distance between the sensor 420 and the second sensor triggering element 412 becomes d1, and d3 is greater than d1. Therefore, the sensor 410 can sense that the distance between the sensor 420 and the sensor triggering element 412 decreases.

[0079] Therefore, based on the fact that the sensor 420 senses that the distance to the sensor triggering element 410 decreases twice, the detection unit can determine that the rotation direction of the rotating component 100 is the first rotation direction (specifically, the clockwise direction).

[0080] According to the same principle, FIG. 16E to FIG. 16A During the process, that is, the outer ring 130 rotates counterclockwise by an angle α, the sensor 420 can sense that the distance between it and the sensor trigger element 410 changes from d1 to d3, then the sensor 420 cannot sense any other sensor trigger elements 410, and then the sensor 420 can sense that the distance between it and the sensor trigger element 410 changes from d2 to d1.

[0081] Therefore, based on the fact that the sensor 420 senses that the distance to the sensor triggering element 410 increases twice, the detection unit can determine that the rotation direction of the rotating component 100 is the second rotation direction (specifically, counterclockwise).

[0082] Therefore, when the gear position of the vehicle is currently in R gear, D gear or P gear, when the rotating component 100 rotates from one angular position along the first rotation direction or the second rotation direction to another angular position, the controller determines that the gear position to be switched is N gear. When the gear position of the vehicle is currently in N gear, when the rotating component 100 rotates from one angular position along the first rotation direction to another angular position, the controller determines that the gear position to be switched is D gear. When the gear position of the vehicle is currently in N gear, when the rotating component 100 rotates from one angular position along the second rotation direction to another angular position, the controller determines that the gear position to be switched is R gear.

[0083] Although the above shift operation is a valid shift request, when the shift device has no fault and the shift operation does not satisfy the one-rotation condition (ie, a shift error operation occurs), the controller may not determine the gear to be switched but maintain the original gear.

[0084] As described above, when the outer ring 130 rotates at an angle less than the angle (α / 2), the positioning member 220 climbs from the valley 140 to the peak 150 and does not cross the peak 150 but falls back from the peak 150 to the original valley 140. Therefore, for the sensor 420 trigger element, when the outer ring 130 rotates at an angle less than the angle (α / 2), the sensor trigger element 410 (for example, the first sensor trigger element 411) disposed opposite to the sensor 420 will return to the position opposite to the sensor 420 after moving away from the sensor 420.

[0085] and Fig.16A and Fig. 16B The same situation is shown, the sensor 420 can sense that the distance between the sensor 420 and the first sensor triggering element 411 is d1. Under the rotation operation, the outer ring 130 rotates clockwise, and the first sensor triggering element 411 gradually moves away from the sensor 420, and the sensor 420 can sense that the distance between the sensor 420 and the first sensor triggering element 411 becomes d2. d2 is less than d1, so the sensor 420 can sense that the distance between the sensor 420 and the sensor triggering element 410 is reduced. Further, the sensor 420 cannot sense the first sensor triggering element 411, nor can it sense any other sensor triggering element 410.

[0086] Subsequently, the first sensor triggering element 411 returns to the position opposite to the sensor 420. The sensor 420 can sense that the distance between the first sensor triggering element 411 and the first sensor triggering element 411 becomes d2. Then, the sensor 420 can sense that the distance between the first sensor triggering element 411 and the first sensor triggering element 411 becomes d1. Since d2 is less than d1, the sensor 420 can sense that the distance between the sensor triggering element 410 and the first sensor triggering element 410 increases. Therefore, in the above process, the sensor 420 can sense that the distance between the sensor triggering element 410 decreases once and then increases once.

[0087] According to the same principle, when the outer ring 130 rotates counterclockwise at an angle less than (α / 2), the sensor 420 can sense that the distance between the sensor trigger element 410 and the sensor trigger element 410 changes from d1 to d3. Then the sensor 420 cannot sense any other sensor trigger element 410. Then the first sensor trigger element 411 returns to the position relative to the sensor 420, and the sensor 420 can sense that the distance between the sensor trigger element 410 and the sensor trigger element 410 changes from d3 to d1. Therefore, the sensor 420 can sense that the distance between the sensor trigger element 410 increases once and then decreases once.

[0088] Therefore, based on the fact that the distance between the sensor 420 and the sensor trigger element 410 increases once and decreases once (specifically, including two situations: decreasing once and then increasing once and increasing once and then decreasing once), the detection unit can determine that the rotation direction of the rotating component 100 is a combination of the first rotation direction and the second rotation direction.

[0089] Therefore, when the vehicle is currently in any one of the R gear, D gear, N gear and P gear, when the rotating component 100 rotates from an angular position in the first rotation direction or the second rotation direction, and then the rotating component 100 returns to the original angular position in the opposite rotation direction, the controller does not perform the determination of the gear to be switched and maintains the current gear of the vehicle.

[0090] In a specific embodiment, the sensor trigger element 410 may be a magnetic paint, and cutouts are provided at intervals of an angle α along the circumferential direction on the bottom surface of the outer ring 130, one surface of the cutout is inclined at a predetermined angle θ relative to the bottom surface of the outer ring 130, and the magnetic paint is coated on the surface of the cutout. The sensor 420 may be a magnetic field measurement sensor that detects magnetic field strength using the Hall effect.

[0091] Re-reference Figures 1 to 5In an embodiment of the present invention, the shifting device of the vehicle may further include a circuit board 500. The circuit board 500 is disposed below the fixed shaft 210. In one example, the circuit board may be connected to the lower box body 320. The sensor 420 may be disposed on the circuit board 500. The circuit board 500 may be a printed circuit board (PCB). The above-mentioned detection unit and controller may be part of a microcontroller unit (MCU) of the PCB.

[0092] In this embodiment, the MCU of the PCB can perform the following two processes: a process of determining the rotation direction of the rotating component 100, and a process of determining the gear position according to the current gear position of the vehicle and the rotation direction of the rotating component determined by the determination process. In one example, the vehicle controller can feed back the gear position information of the vehicle to the MCU of the PCB. After the MCU of the PCB determines the gear position to be switched, the MCU of the PCB sends the determined gear position signal to be switched to the transmission control unit (TCU), and the TCU performs electronic shift control.

[0093] The shift device according to an embodiment of the present invention further includes a park (Park, P) gear button 600, which can move axially (i.e., along the axis J) at the center of the fixed shaft 210 under a pressing operation, and can return to the position before pressing after the pressing operation is removed.

[0094] Specifically, the circuit board 500 is covered with a damping sheet 510, and the parking gear button 600 is located above the damping sheet 510. When the driver presses the parking gear button 600, the damping sheet 510 disposed below the parking gear button 600 is elastically compressed and contacts the circuit board 500. The circuit board 500 can recognize the operation of the parking gear button and output a shift signal for the P gear. When the driver releases the parking gear button 600, the parking gear button 600 that has moved downward returns upward to its initial position due to the restoring force of the damping sheet 510.

[0095] In addition, in various embodiments of the present invention, other function buttons such as auto hold, drive mode, feedback brake mode, etc. can be integrated into the shift-by-wire (SBW) system to reduce development costs and save space in the vehicle console. Therefore, the vehicle's shift device can further include a first function button 710, a second function button 720, and a third function button 730.

[0096] As an example, the first function button 710 may be an automatic parking button, the second function button 720 may be a driving mode button, and the third function button 730 may be a feedback braking mode button. Therefore, the driver can select the automatic parking mode, driving mode and feedback braking mode by operating the vehicle's shift device.

[0097] However, the present invention is not limited thereto, and the first function button 710 may be a lane keeping assist (Lane Keeping Assist, LKA) button, the second function button 720 may be a 360° camera button, and the third function button 730 may be an automated parking system (Automated Parking System, APS) button.

[0098] Each of the first function button 710, the second function button 720 and the third function button 730 passes through the button opening 312 of the upper box body 310 and is arranged above the damping plate 510. Similar to the key principle of the parking gear button 600, when the driver presses any one of the first function button 710, the second function button 720 and the third function button 730, the damping plate 510 arranged below the pressed function button is elastically compressed and contacts the circuit board 500. The circuit board can identify the operation of the function button and output the corresponding control signal. When the driver releases the function button, the function button that has moved downward returns to the initial position upward by the restoring force of the damping plate 510. Specifically, each of the first function button 710, the second function button 720 and the third function button 730 can include a button cap 740 and a button guide column 750.

[0099] However, the parking gear button 600 , the first function button 710 , the second function button 720 , and the third function button 730 are not limited thereto, and these buttons may be configured as other different types of switches.

[0100] FIG. 17A to FIG. 17G 2 is a schematic diagram showing the operation of the shifting device of a vehicle according to an embodiment of the present invention. FIG. 17A to FIG. 17G The driver only needs to control the direction of rotation of the selector button 110 to perform the gear shifting operation, which is simple and convenient to operate. In addition, for convenience, commonly used function buttons are added to the gear shifting device.

[0101] like Fig.17A As shown, when the driver desires to shift from the R / N / D gear to the P gear, the driver can press the parking gear button at the center of the selection button 110. At this time, the vehicle can be switched to the P gear.

[0102] like Fig. 17BAs shown in FIG. 1 , when the driver desires to shift from the P / R / D gear to the N gear, the driver can rotate the selector knob 110 clockwise or counterclockwise once. At this time, the vehicle can be switched to the N gear.

[0103] like Fig. 17C As shown in FIG. 1 , when the driver desires to shift from the N gear to the R gear, the driver can rotate the selector knob 110 counterclockwise once. At this time, the vehicle can be switched to the R gear.

[0104] like Fig.17D As shown in FIG. 1 , when the driver desires to shift from the N gear to the D gear, the driver can rotate the selector knob 110 clockwise once. At this time, the vehicle can be switched to the D gear.

[0105] like Fig.17E As shown in the figure, when the driver wants to shift from P / D gear to R gear, the driver can rotate the selector knob counterclockwise twice. Specifically, in the first rotation operation, the vehicle is switched from P gear or D gear to N gear, and in the second rotation operation, the vehicle is switched from N gear to R gear, thereby switching to the driver's target gear R gear.

[0106] like Fig.17F As shown in the figure, when the driver wants to shift from P / R gear to D gear, the driver can rotate the selector button clockwise twice. Specifically, under the first rotation operation, the vehicle is switched from P gear or R gear to N gear, and under the second rotation operation, the vehicle is switched from N gear to D gear, thereby switching to the driver's target gear D gear.

[0107] like Figure 17G As shown, when the driver wants to select automatic parking mode, driving mode or regenerative braking mode, the driver can press the corresponding function button.

[0108] In addition, an embodiment of the present invention further provides a vehicle shifting method, which is applied to a shifting device having a rotating component 100, and the shifting method includes: when the current gear position of the vehicle is R gear, D gear or P gear, when the rotating component 100 rotates from one angular position to another angular position along the first rotation direction or the second rotation direction, switching to N gear. When the current gear position of the vehicle is N gear, when the rotating component 100 rotates from one angular position to another angular position along the first rotation direction, switching to D gear. When the current gear position of the vehicle is N gear, when the rotating component 100 rotates from one angular position to another angular position along the second rotation direction, switching to R gear.

[0109] The gear shifting method further includes: when the vehicle is currently in any one of the R gear, D gear, N gear and P gear, when the rotating component 100 rotates from an angular position along the first rotation direction or the second rotation direction, and then the rotating component 100 returns to the original angular position in the opposite rotation direction, the gear is not switched and the current gear of the vehicle is maintained.

[0110] The shifting device according to the embodiment of the present invention does not set the Null position and the operating positions corresponding to the N gear, the R gear and the D gear, nor does it have a return component for returning the rotating component to the Null position. The rotating component 100 of the shifting device is always in a stable state of being maintained at one of the angular positions before and after the shifting, and the operation feeling felt by the driver is the same and clear regardless of shifting to the D gear or the R gear or shifting to the N gear. Specifically, the driver can feel the elastic force of the elastic member 250 in the compressed state when the positioning member 220 reaches the peak 150 and the release of the above elastic force when the positioning member 220 reaches the valley 140.

[0111] In addition, the driver does not need to rotate the rotating component 100 to a specific angle, but only needs to control the rotating direction of the rotating component 100 to perform the gear shifting operation, which is simple and convenient to operate.

[0112] In addition, setting up multiple function buttons in the vehicle's shift device, for example, integrating functions such as automatic parking, feedback braking mode and driving mode into SBW can reduce development costs, save space for console packaging, and increase convenience.
