Description

Technical Field

[0001] This invention relates to a vehicle transmission device and its operating method, and more specifically, to a vehicle transmission device and its operating method that can easily identify the vehicle status through a transmission operation unit for transmission operation. Background Technology

[0002] The transmission can have different gear ratios to keep the engine rotation constant according to the vehicle speed, and the driver can change the gear ratios of the transmission by operating the gear lever.

[0003] The transmission system offers the following transmission modes: manual transmission mode, which allows the driver to manually switch gears; and automatic transmission mode, which automatically switches gear ratios based on vehicle speed when the driver selects drive (D).

[0004] At the same time, a sport mode is being used that can perform manual and automatic transmissions in one transmission. In the sport mode, while the automatic transmission is performed in the basic way, a manual transmission is provided next to the automatic transmission so that the driver can perform manual transmission by upshifting or downshifting.

[0005] At this point, the gear lever only serves to enable the driver to select the gear, so a solution is needed that can provide more information through the gear lever.

[0008] (Patent Document 1) Korean Patent Publication No. 10-1327137 (Published on November 8, 2013) Summary of the Invention

[0009] The present invention was proposed to solve the above-mentioned problems. The technical problem to be solved by the present invention is to provide a vehicle transmission device and its operation method that enable the driver to easily identify the vehicle status based on the position of the transmission operation unit.

[0010] The subject matter of this invention is not limited to the subject matter mentioned above, and other subject matters not mentioned can be clearly understood by those skilled in the art from the description below.

[0011] To achieve the aforementioned objective, a vehicle transmission device according to an embodiment of the present invention may include: a vehicle state sensing unit for sensing a vehicle state including a vehicle start-off state (including a start-preparation state) and a vehicle start-on state (including a second start-on state); a transmission operation unit for performing a transmission operation to select any one of a plurality of gears; and a position adjustment unit for adjusting the position of the transmission operation unit according to the sensed vehicle state, so that the transmission operation unit slides from a first position blocking transmission operation to a second position allowing transmission operation.

[0012] The first state may include an internal combustion engine vehicle with its engine not driven or an electric vehicle being unable to move, and the second state may include an internal combustion engine vehicle with its engine driven or an electric vehicle being able to move.

[0013] When the gear shifting unit slides to the second position, the initial gear shift position is P or N. When at least one shifting condition is met, other gear shift positions can be selected from P or N.

[0014] The start-up preparation state can be the expected state of vehicle operation when the vehicle is started and stopped.

[0015] The speed control unit may include: a light-emitting module that generates light to form a lit image of a predetermined shape.

[0016] In the first state, the light-emitting module can form a lit image for the welcoming function; in the second state, the light-emitting module can form a lit image showing the current gear position.

[0017] The position adjustment unit can cause at least a portion of the speed change operation unit to move up and down relative to the direction of the sliding movement, so as to be located at either the first position or the second position.

[0018] It may also include: a speed-changing unit, which is combined with the speed-changing operation unit and is capable of changing speed according to the speed-changing operation of the speed-changing operation unit, wherein the position of the speed-changing unit can be adjusted by the position adjustment unit to have a position corresponding to either the first position or the second position.

[0019] The position adjustment unit may include: a drive unit that generates a driving force for adjusting the position of the transmission operation unit; and a guide unit that guides the position of the transmission unit so as to adjust the position of the transmission operation unit according to the driving force of the drive unit.

[0020] The guide portion may include: a lead screw that rotates about a rotation axis by the driving force of the drive portion; and a nut component that moves along the rotation axis of the lead screw according to the rotation direction of the lead screw.

[0021] The nut component may include: a guide groove into which a guide protrusion formed in the transmission part is inserted, so as to allow the transmission part to slide when the lead screw rotates.

[0022] The guide protrusion moves along a guide rail formed in the transmission housing as the lead screw rotates.

[0023] The guide rail can be configured such that its two ends have different heights, so that the guide protrusions are positioned at different heights relative to the direction of the sliding movement in the first and second positions.

[0024] The guide groove can be formed to extend relatively long in one direction so that the guide protrusion can move up and down with reference to the sliding movement direction.

[0025] To achieve the aforementioned objective, an operation method for a vehicle transmission device according to an embodiment of the present invention may include the following steps: sensing a vehicle state including a vehicle start-off state (including a start-preparation state) and a vehicle start-on state (including a second start-up state); and, based on the sensed vehicle state, causing a transmission operation unit capable of performing a transmission operation for selecting any one of a plurality of gears to slide from a first position blocking transmission operation to a second position allowing transmission operation.

[0026] The sliding movement step may include the following steps: in the second state, the speed change operation unit slides from the first position to the second position.

[0027] The sliding movement step may further include the following steps: when the gear shifting operation unit slides from the first position to the second position, at least a portion of the gear shifting operation unit is raised or lowered.

[0028] It may also include the following steps: when the speed change operation unit is located in either the first position or the second position, a light-up image of a predetermined shape is formed from the light-emitting module disposed in the speed change operation unit.

[0029] The step of forming the illuminated image may include the following steps: when the gear shifting operation unit is in the first position, an illuminated image for the welcome function is formed, and when the gear shifting operation unit is in the second position, an illuminated image representing the current gear shift is formed.

[0030] Other specific aspects of the present invention are included in the detailed embodiments and the accompanying drawings.

[0031] The vehicle transmission device and its operating method according to the present invention, as described above, have one or more of the following effects.

[0032] Because the position of the gear shifter is adjusted to vary depending on the vehicle's condition, the driver can more easily identify the vehicle's status by observing the position of the gear shifter, thus improving driver convenience.

[0033] The effects of this invention are not limited to those mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the scope of the claims. Attached Figure Description

Moreover, in the various figures illustrated in this invention, the constituent elements may be shown in slightly enlarged or reduced form for ease of explanation.

[0060] Hereinafter, the present invention will be described with reference to the accompanying drawings, which are used to describe a transmission device for vehicles and its operation method, based on embodiments of the present invention.

[0061] Figure 1 This is a block diagram illustrating the configuration of a vehicle transmission device according to an embodiment of the present invention. Figure 2 This is a schematic diagram illustrating a vehicle transmission device according to an embodiment of the present invention. Figure 3 This is a perspective view showing a vehicle transmission device according to an embodiment of the present invention. Figure 4 This is a side view showing a vehicle transmission device according to an embodiment of the present invention. Figure 5 This is a plan view illustrating a vehicle transmission device according to an embodiment of the present invention.

[0062] Reference Figures 1 to 5 According to an embodiment of the present invention, a vehicle transmission device 1 may include a vehicle status sensing unit 100, a transmission operation unit 200, and a position adjustment unit 300.

[0063] In an embodiment of the present invention, the case in which the vehicle transmission device 1 is installed in the central control console C between the central instrument panel and the glove compartment of the vehicle is described as an example, but it is not limited thereto. The vehicle transmission device 1 of the present invention can be installed in a variety of locations that are easily accessible to the driver so as to perform gear shifting operations.

[0064] The vehicle state sensing unit 100 can sense at least one vehicle state for activating the transmission operation unit 200. Activation of the transmission operation unit 200 can be understood as being switched to a state where the driver's transmission operation can be performed.

[0065] In an embodiment of the present invention, an example will be given of a vehicle state sensing unit 100 sensing multiple vehicle states that are different from each other. This is so that the transmission operation unit 200 can be positioned at one of multiple different positions based on the vehicle state sensed by the vehicle state sensing unit 100. A detailed explanation of this will be given later.

[0066] The vehicle status sensing unit 100 can sense a first state of vehicle start-off, including a start-preparation state, and a second state of vehicle start-on. However, the vehicle status sensed by the vehicle status sensing unit 100 is not limited to the above example. Depending on the vehicle status required to activate the transmission operation unit 200, the vehicle status sensed by the vehicle status sensing unit 100 can be added, deleted, and changed.

[0067] The first state can include the expected vehicle operation and the unexpected vehicle operation when the vehicle is in the start-up and stop-down state. The start-up preparation state can be understood as the expected vehicle operation when the vehicle is in the start-up and stop-down state.

[0068] At this point, the first state can be understood as the engine of an internal combustion engine vehicle not being driven or the electric vehicle being unable to move, while the second state can be understood as the engine of an internal combustion engine vehicle being driven or the electric vehicle being able to move.

[0069] In addition, the start-up preparation state can be understood as a state of anticipated vehicle operation, such as the door being opened when the vehicle is started and closed, or a driver with a smart key approaching the vehicle, or the presence of a passenger being sensed, or the activation of the brakes.

[0070] The sensing results of the vehicle status sensing unit 100 can be sent to a controller such as an ECU, and the controller can generate a control signal for adjusting the position of the transmission operation unit 200 based on the sensed vehicle status.

[0071] The transmission operation unit 200 enables the driver to perform transmission operation. Its position is adjusted according to the vehicle status sensed by the vehicle status sensing unit 100, so that the driver can identify the vehicle status.

[0072] The gear shifting operation unit 200 is connected to the gear shifting unit 400 for gear shifting function via a shaft 410. As the gear shifting operation unit 200 rotates around the rotation axis Ax, any one of the multiple gear shifting positions can be selected.

[0073] In an embodiment of the present invention, the example is given where the gear selector is in the order of R, N, D as the gear selector rotates in the first direction, and in the order of D, N, R as the gear selector rotates in the second direction. However, the invention is not limited to this. The selectable gears as the gear selector rotates can be varied. Some gears, including the P gear, can also be selected using buttons or switches that are independently provided with the gear selector.

[0074] Furthermore, in the embodiments of the present invention, the case in which the first direction is clockwise and the second direction is counterclockwise is used as an example for explanation.

[0075] The transmission unit 400 can output a transmission signal corresponding to the position of the transmission operation unit 200. The transmission signal output from the transmission unit 400 can be transmitted to the transmission and switched to the selected transmission gear by the transmission operation unit 200.

[0076] Figures 6 to 8 This is a plan view showing the speed-changing section according to an embodiment of the present invention.

[0077] Reference Figures 6 to 8 According to an embodiment of the present invention, the speed change unit 400 may include a rotating component 420 that rotates integrally with the shaft 410 and a stop groove 430 for generating an operating feel when the rotating component 420 rotates.

[0078] When the shift operation unit 200 rotates, the rotating member 420 rotates by the rotation of the shaft 410 coupled to the shift operation unit 200. The bullet member 421 located at the end of the rotating member 420 moves while maintaining contact with the stop groove 430. Therefore, an operating sensation can be generated based on the shape of the surface in contact with the bullet member 421 in the stop groove 430.

[0079] At this time, the projectile component 421 is elastically supported in the radial direction with the rotation axis Ax as the center by the elastic component (not shown), so that it can maintain contact with the stop groove 430 when the shaft 410 rotates.

[0080] The stop groove 430 can provide a tactile feedback when the gear shifting unit 200 rotates, and can also return the gear shifting unit 200 to its initial position when the external force applied to the gear shifting unit 200 is removed in order to select a gear.

[0081] At this time, the initial position refers to the position before an external force is applied to the transmission operation unit 200 in order to select a gear. Depending on the rotation direction of the transmission operation unit 200, if the position returned when the external force applied to the transmission operation unit 200 is removed is the same, there can be one initial position. If the initial positions returned when the external force applied to the transmission operation unit 200 is removed are different from each other, there can be two or more initial positions.

[0082] In the following embodiments of the present invention, we will take the case where the initial positions of the gear shifting units 200 are different from each other depending on the rotation direction of the gear shifting unit 200 as an example. The initial position of the gear shifting unit 200 is referred to as the NULL gear. The NULL gear can correspond to the gear selected before returning to the initial position.

[0083] at this time, Figures 6 to 8 This is an example of a case that includes multiple stop grooves 431 and 432 corresponding to the Nr and Nd gears, which are NULL gears. When the external force is removed after selecting the D gear by rotating the gear shifting unit 200, the gear can return to the stop groove 431 corresponding to the Nd gear among the multiple stop grooves 431 and 432. Conversely, when the external force is removed after selecting the R gear, the gear can return to the stop groove 432 corresponding to the Nr gear among the multiple stop grooves 431 and 432.

[0084] The Nd and Nr gears can be understood as N gears. When the external force applied to the gear shifting unit 200 is removed and the gear shifting unit 200 returns to its initial position, the gear shifting unit is selected according to the gear shifting selection sequence described above.

[0085] For example, after the transmission control unit 200 is rotated in the first direction to select the D gear and the external force applied to the transmission control unit 200 is removed to return to the Nd gear, the driver can rotate the transmission control unit 200 in the second direction to select the transmission gear in the order of Nr and R. Conversely, after the transmission control unit 200 is rotated in the second direction to select the R gear and the external force applied to the transmission control unit 200 is removed to return to the Nr gear, the driver can rotate the transmission control unit 200 in the first direction to select the transmission gear in the order of Nd and D.

[0086] That is, the Nd and D gears can be understood as the gear shifting unit 200 rotating in the same direction but with different rotation angles. Similarly, the Nr and R gears can also be understood as the gear shifting unit 200 rotating in the same direction but with different rotation angles.

[0087] At this time, a first contact surface 431a can be formed along the first direction from the stop groove 431 corresponding to the Nd stop among the multiple stop grooves 431, 432, and a second contact surface 432a can be formed along the second direction from the stop groove 432 corresponding to the Nr stop.

[0088] The first contact surface 431a is formed such that the further away from the stop groove 431 corresponding to the Nd gear, the closer it is to the rotation axis Ax of the shift operation unit 200. Similarly, the second contact surface 432a is formed such that the further away from the stop groove 432 corresponding to the Nr gear, the closer it is to the rotation axis Ax of the shift operation unit 200. The closer the contact position between the projectile component 421 and any one of the first contact surface 431a and the second contact surface 432a is to the rotation axis Ax, the greater the elastic deformation rate of the elastic component that elastically supports the projectile component 421, thereby increasing the restoring force. When the external force is removed, this restoring force allows the projectile component 421 to return to any one of the multiple stop grooves 431 and 432.

[0089] The above Figure 6This is an example of a case where the projectile component 421 is inserted into the stop groove 431 corresponding to the Nd stop among multiple stop grooves 431, 432. In this case, as... Figure 7 As shown, after the gear shifting unit 200 is rotated in the second direction to select the reverse gear and the external force is removed, as... Figure 8 As shown, the projectile component 421 returns to the stop groove 432 corresponding to the Nr stop among the plurality of stop grooves 431, 432.

[0090] In the above embodiment, the case in which the shift operation unit 200 returns to its initial position when the external force applied to the shift operation unit 200 for selecting a shift gear is removed is described as an example, but it is not limited to this. The shift operation unit 200 can maintain a position corresponding to the selected shift gear, and in this case, the stop groove 430 can be formed with a stop groove corresponding to the shift gear that can be selected by the shift operation unit 200 in the rotation direction of the shift operation unit 200.

[0091] The position of the gear shifting unit 200 can be adjusted to have either a first position or a second position. Hereinafter, in the embodiments of the present invention, the first position refers to the position of the gear shifting unit 200 that prevents the driver from performing gear shifting operations when gear shifting operations are not required (i.e., the first state), and the second position refers to the position of the gear shifting unit 200 that allows the driver to perform gear shifting operations when gear shifting operations are required (i.e., the second state).

[0092] In an embodiment of the present invention, when the vehicle is started, the transmission operation unit 200 is positioned in a second position so that the driver can easily recognize that the vehicle has been started.

[0093] That is, when an internal combustion engine vehicle is started, the driver can easily identify that the vehicle is started due to engine noise or vibration. Conversely, since electric vehicles use the driving force of a motor as a power source, they do not produce engine noise or vibration, making it difficult for the driver to identify when the vehicle is started. Therefore, in the embodiments of the present invention, the position of the transmission operation unit 200 is adjusted when the vehicle is started, so that the driver can easily identify the vehicle start-up status not only in internal combustion engine vehicles but also in electric vehicles.

[0094] The position adjustment unit 300 can adjust the position of the transmission operation unit 200 so that the transmission operation unit 200 slides and moves to either the first position or the second position according to the control signal of the controller. In the embodiment of the present invention, the case in which the initial transmission gear is P or D when the transmission operation unit 200 slides to the second position is explained as an example, and the case in which other transmission gears can be selected when at least one transmission condition (including vehicle speed or whether the brake is activated) is met is explained as an example.

[0095] The position adjustment unit 300 may include a drive unit 310 and a guide unit 320.

[0096] The drive unit 310 can generate a driving force for adjusting the position of the transmission operation unit 200, and the guide unit 320 can adjust the position of the transmission operation unit 200 by means of the driving force of the drive unit 310.

[0097] When a driving force is generated from the drive unit 310, the guide unit 320 causes the gear shifting operation unit 200 to slide and adjust its position. Hereinafter, in the embodiment of the present invention, the case in which the gear shifting operation unit 200 slides in the horizontal direction by means of the guide unit 320 will be described as an example.

[0098] That is, the gear shifting unit 200 can be placed in a first position where the gear shifting unit 200 can be placed in a cover 500 that does not allow the interior to be seen from the outside. In a second position, at least a portion of the gear shifting unit 200 is set to detach from the cover 500, so that the driver can grasp the gear shifting unit 200 to perform gear shifting operations. In this case, the cover 500 can be formed with an opening (not shown) that allows the gear shifting unit 200 to slide, and the shaft 410 can be connected to the gear shifting unit 200 through the opening.

[0099] At this time, the guide 320 positions at least a portion of the shift operation unit 200 at a height different from that of the first position in the second position in a direction perpendicular to the direction of sliding movement of the shift operation unit 200, thereby making it easier for the driver to grip the shift operation unit 200 and perform shift operations.

[0100] For example, when the gear shifting operation unit 200 is configured to be integrally mounted on the mounting cover 500, it is difficult for the driver to grip the gear shifting operation unit 200. Therefore, in an embodiment of the present invention, at least a portion of the gear shifting operation unit 200 is raised while it slides, so that the driver can grip the gear shifting operation unit 200 and perform gear shifting operations.

[0101] The guide portion 320 may include a lead screw 321 and a nut component 322.

[0102] The lead screw 321 can rotate around the rotation axis 311 of the drive unit 310. The nut component 322 can move along the rotation axis direction of the lead screw 321 when the lead screw 321 rotates. A guide groove 322a is formed in the nut component 322. The guide protrusion 440 formed in the transmission unit 400 is inserted into the guide groove 322a. As the nut component 322 moves along the rotation axis direction of the lead screw 321, the transmission operation unit 200 can slide along the rotation axis direction of the lead screw 321.

[0103] At this time, the guide protrusion 440 is configured to move along the guide rail 441 formed in the transmission housing (not shown). The two ends of the guide rail 441 are formed with different heights relative to the rotation axis direction of the lead screw 321, so that the guide protrusion 440 has different heights relative to each other when it is located at one end of the guide rail 441 and when it is located at the other end of the guide rail 441.

[0104] Furthermore, the guide groove 322a formed in the nut component 322 can be formed to extend longer in the vertical direction so that the guide protrusion 440 can move up and down in the vertical direction depending on the different heights formed at the two ends of the guide rail 441.

[0105] At this time, the vertical movement of the guide protrusion 440 is an example of the guide protrusion 440 sliding in the horizontal direction. The actual direction of the vertical movement of the guide protrusion 440 can vary depending on the direction of the sliding movement of the guide protrusion 440.

[0106] Therefore, when the shift operation unit 200 is in the first position, the guide protrusion 440 is located at one end of the guide rail 441 and at the lower end of the guide groove 332a. When the position of the shift operation unit 200 is adjusted to the second position by the position adjustment unit 300, as... Figures 9 to 12 As shown, the guide protrusion 440 is located at the other end of the guide rail 441 and at the upper end of the guide groove 332a, so that the driver can grasp the gear shifting unit 200 and perform gear shifting operations.

[0107] As described above, when the position of the transmission operation unit 200 is adjusted from the first position to the second position, such as Figure 13 As shown, the driver grasps the gear shifting unit 200 and rotates it in either the first or second direction with the rotation axis Ax as the center, thereby selecting any gear among R, N, and D.

[0108] In addition, the speed change operation unit 200 may include a light-emitting module 210 for forming a lit image of a predetermined shape.

[0109] For example, in a first state, the light-emitting module 210 causes the vehicle to exhibit a response similar to welcoming the driver, thereby forming a illuminated image that highlights the welcoming function between the vehicle and the driver. In this case, the light-emitting module 210 can form an illuminated image with at least one color from at least a portion of the vehicle.

[0110] In addition, such as Figure 14 As shown, in the second state, the light-emitting module 210 can display the illuminated image I representing the current gear, so that the current gear selected by the driver can be easily identified, and Figure 14 This is an example of selecting the D gear.

[0111] In addition, when the vehicle stops running and the vehicle is turned off, the light-emitting module 210 can form a pre-defined illuminated image, or gradually increase or decrease the brightness of the illuminated image, so that the driver can recognize that the vehicle has been turned off.

[0112] In the above embodiment, the example described is that when the vehicle is started and the transmission operation unit 200 slides along the guide unit 320, at least a portion of it rises and falls, so that the transmission operation unit 200 is located in either the first position or the second position. However, this is only one example to help understand the present invention and is not limited thereto. The sliding movement of the transmission operation unit 200 can be omitted and the transmission operation unit 200 can be raised and lowered to be located in either the first position or the second position. Conversely, the raising and lowering of the transmission operation unit 200 can be omitted and the transmission operation unit 200 can be slid along to be located in either the first position or the second position.

[0113] In the vehicle transmission device 1 of the present invention, the transmission operation units 200 are positioned differently depending on the vehicle status, so that the vehicle start-up / stop of not only internal combustion engine vehicles but also electric vehicles can be easily identified by the driver. Therefore, even if the driver has difficulty identifying, for example, that the vehicle start-up of an electric vehicle has been turned on, it is possible to prevent personal injury or vehicle accidents caused by the driver's negligence in advance.

[0114] Those skilled in the art will understand that the invention can be implemented in other specific forms without altering the technical concept or essential features. Therefore, the embodiments described above are exemplary in all respects and should be understood as not limiting.
