Description

TECHNICAL FIELD

[0001] The present disclosure relates to an electronic shift operation apparatus, and more particularly, to a technology related to an electronic shift operation apparatus capable of switching a mode of shift operation to manual shift and automatic shift according to a driver's intention. BACKGROUND

[0002] Generally, a vehicle equipped with an automatic transmission allows a shift gear to be automatically operated within a target shift position range by controlling hydraulic pressure within a shift range set according to a driving speed of the vehicle.

[0003] An automatic transmission creates a gear ratio by using a hydraulic circuit, a planetary gear, and a friction element to perform a shift operation, and a transmission control unit (TCU) controls the constituent components.

[0004] Unlike a mechanical transmission system in the related art, a shift-by-wire (SBW) system, which is an electronic transmission system of a vehicle, refers to an electronic transmission system having no mechanical connection structure such as a cable between a transmission and a shift lever. When a sensor value generated when a shift mechanism (shift lever, shift button, or shift dial) is manipulated is transmitted to a transmission control unit (TCU), the TCU performs electronic shift control in response to the indicated signal.

[0005] Accordingly, an automatic transmission based on SBW operation can smoothly perform a shift operation for a D (drive) range, an R (reverse) range, an N (neutral) range, and the like by simply manipulating an electronic shift mechanism, which transmits a driver's shift intention to the TCU as an electric signal. In addition, the shift mechanism can be miniaturized, which can secure a large space between a driver's seat and a passenger's seat.

[0006] The above-described background explanations are intended only to assist in understanding the background of the present disclosure and are not intended to represent the prior art that is already known to those skilled in the art. SUMMARY

[0054] Hereinafter, an electronic shift operation apparatus according to an exemplary embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0055] The electronic shift operation apparatus according to the present disclosure includes a mode switching device capable of switching a mode of a shift operation to automatic shifting or manual shifting based on an intention of a driver. Accordingly, simplicity of the shift operation can be eliminated, which can provide fun for the driver and improve marketability.

[0056] Further, the electronic shift operation apparatus according to the present disclosure can include a stroke limiting device capable of limiting a shift direction stroke of a shift lever differently according to the automatic shifting mode and the manual shifting mode.

[0057] Generally, the shift direction stroke of the shift lever is relatively shorter in the automatic shifting mode than in the manual shifting mode, which can improve operation convenience.

[0058] On the contrary, the shift direction stroke of the shift lever is relatively longer in the manual shifting mode than in the automatic shifting mode, which can improve recognition performance during the shift operation.

[0059] Further, the electronic shift operation apparatus according to the present disclosure can include a system implementing the mode switching device for the shift operation and the stroke limiting device for limiting the shift direction stroke of the shift lever.

[0060] First, the mode switching device capable of switching the mode to the automatic shifting mode or the manual shifting mode based on the intention of the driver will be described.

[0061] An electronic shift operation apparatus according to the disclosure can include a ball cover 20 coupled to a shift lever 10 and configured to rotate in a selection direction and a shift direction when the shift lever 10 is manipulated by a driver, a hinge shaft 30 coupled to the ball cover 20 and configured to rotate together with the ball cover 20 when the ball cover 20 rotates in the selection direction and to serve as a rotation center of the ball cover 20 when the ball cover 20 rotates in the shift direction, a mode switch lever 40 coupled to one end of the hinge shaft 30 and configured to be movable in a longitudinal direction of the hinge shaft 30, and a mode switch guide 50 into which an end of the mode switch lever 40 is inserted, the mode switch guide 50 having a first selection groove 51 configured to guide movement of the mode switch lever 40 in the selection direction in an automatic shift mode and a second selection groove 52 configured to guide movement of the mode switch lever 40 in the selection direction in a manual shift mode.

[0062] The shift lever 10 can have a knob 11 with which the driver can hold the knob 11 with his hand to operate the shift lever 10.

[0063] The electronic shift operation apparatus according to the disclosure can be located at a position at which the driver can easily manipulate the shift lever 10. For example, the electronic shift operation apparatus can be installed on a console, a center panel, or the like in a vehicle, or in consideration of an autonomous driving situation, the electronic shift operation apparatus can be installed on a seat.

[0064] The ball cover 20 can be provided in the form of a spherical body having an inside that is empty, or be configured as an assembly of a semi-spherical upper cover and a lower cover.

[0065] The hinge shaft 30 can be configured as a hollow shaft having an inside that is empty and penetrate the ball cover 20 in the selection direction.

[0066] When the ball cover 20 rotates in the selection direction by being manipulated by the shift lever 10, the ball cover 20 and the hinge shaft 30 can rotate together. When the ball cover 20 rotates in the shift direction, only the ball cover 20 rotates, and the hinge shaft 30 serves as a rotation center of the ball cover 20 without rotating.

[0067] One end of the mode switch lever 40 can be inserted into one end of the hinge shaft 30. The mode switch lever 40 can be installed to be movable in a longitudinal direction of the hinge shaft 30.

[0068] The other end of the mode switch lever 40 is installed to be inserted into the first selection groove 51 or the second selection groove 52 formed in the mode switch guide 50. The first selection groove 51 and the second selection groove 52 are connected by a connection groove 53.

[0069] When the mode switching guide 50 moves in the shift direction, the mode switching guide 50 can move in a state in which the other end of the mode switching lever 40 is inserted into the connection groove 53, and the other end of the mode switching lever 40 can be located in the first selection groove 51 or the second selection groove 52 by the movement of the mode switching guide 50 in the shift direction.

[0070] The electronic shift operation apparatus according to the present disclosure can further include a ball cover bracket 60 configured to cover the ball cover 20 and guide the rotation of the ball cover 20 in the selection direction and the shift direction.

[0071] The ball cover bracket 60 can be formed in a hexahedral shape and configured as an assembly of an upper bracket and a lower bracket.

[0072] The ball cover 20 can be located in the ball cover bracket 60. An inner surface of the ball cover bracket 60 can be formed in a spherical surface that facilitates the rotation of the ball cover 20 in the selection direction and the shift direction.

[0073] The hinge shaft 30 can penetrate the ball cover 20 in the selection direction. Opposite ends of the hinge shaft 30 protruding to the outside of the ball cover 20 can be mounted to be inserted into a first side groove 61 of the ball cover bracket 60.

[0074] The first side groove 61 can be formed to extend upward and downward in two surfaces located in the ball cover bracket 60 based on the selection direction.

[0075] The two opposite ends of the hinge shaft 30 and the first side groove 61 have portions facing each other in the shift direction and configured to be in surface contact with each other.

[0076] Therefore, when the ball cover 20 is rotated in the shift direction by manipulation of the shift lever 10, the two opposite ends of the hinge shaft 30 are restricted by the first side groove 61, so that the rotation of the hinge shaft 30 in the shift direction can be restricted, and the ball cover 20 can be rotated around the hinge shaft 30 in the shift direction.

[0077] In addition, when the ball cover 20 is rotated in the selection direction by manipulation of the shift lever 10, the ball cover 20 and the hinge shaft 30 are rotated together in the selection direction, and in the illustrated state, the first side groove 61 can extend upward and downward from the side surface of the ball cover bracket 60 to guide the rotation of the hinge shaft 30 in the selection direction.

[0078] As the ball cover 20 is rotated in the selection direction, when the end of the hinge shaft 30 contacts the upper end or the lower end of the first side groove 61, the rotation in the selection direction can be restricted.

[0079] The hinge shaft 30 can be configured as a hollow shaft that is empty inside. One end of the mode switching lever 40 can be inserted into the hinge shaft 30, so that the mode switching lever 40 can move in the longitudinal direction of the hinge shaft 30, and rotation of the mode switching lever 40 can be restrained and restricted by the hinge shaft 30.

[0080] One end of the hinge shaft 30 and one end of the mode switching lever 40 can be formed in a quadrangular cross-sectional shape corresponding to each other.

[0081] Thus, in a state in which one end of the mode switching lever 40 is inserted into one end of the hinge shaft 30, the mode switching lever 40 can only move in the longitudinal direction of the hinge shaft 30, and rotation of the mode switching lever 40 is restricted from being performed by the cross-sectional shape of the hinge shaft 30.

[0082] The electronic shift operation apparatus according to the present disclosure can further include a first spring fixing pin 70 coupled to penetrate a midpoint of the hinge shaft 30 based on the longitudinal direction, and a mode switching spring 80 having both opposite ends connected to one end of the first spring fixing pin 70 and one end of the mode switching lever 40, and configured to provide an elastic force to the mode switching lever 40.

[0083] The first spring fixing pin 70 is coupled to penetrate the midpoint of the hinge shaft 30 in the longitudinal direction in the shift direction.

[0084] The mode switching spring 80 can be configured as a coil spring, and provide a spring force to pull the mode switching lever 40 toward the inside of the hinge shaft 30.

[0085] The electronic shift operation apparatus according to the present disclosure can further include a mode switching guide bracket 90 fixedly coupled to one side of the ball cover bracket 60 into which the mode switching guide 50 is inserted and mounted to be movable in the shift direction, and a mode switching solenoid 110 fixedly coupled to the plate 100 coupled to the mode switching guide bracket 90, connected to the mode switching guide 50, configured to move the mode switching guide 50 in the shift direction during operation, and configured to be operated by receiving an automatic shift mode signal or a manual shift mode signal.

[0086] The mode switching guide bracket 90 can be fixedly coupled to a side surface of the ball cover bracket 60 in which the first side groove 61 is formed.

[0087] The mode switching guide bracket 90 is empty inside, and the mode switching guide 50 is inserted and mounted into the mode switching guide bracket 90. When the mode switching solenoid 110 is operated, the mode switching guide 50 can move in the shift direction in a state in which the mode switching guide 50 is inserted into the mode switching guide bracket 90.

[0088] The plate 100 is fixedly coupled to the mode switching guide bracket 90, and the mode switching solenoid 110 is fixedly coupled to the plate 100.

[0089] The mode switching solenoid 110 can be connected to the mode switching guide 50. When the mode switching solenoid 110 can be operated, the mode switching guide 50 can be moved in the shift direction in a state in which the mode switching guide 50 is inserted into the mode switching guide bracket 90.

[0090] When the driver manipulates the mode selection portion 120, an automatic shift mode signal or a manual shift mode signal can be generated. The mode switching solenoid 110 can be operated by receiving the automatic shift mode signal or the manual shift mode signal.

[0091] The mode switching guide 50 can have a first selection groove 51 and a second selection groove 52 into which an end of the mode switching lever 40 is inserted, and a connection groove 53 connecting the first selection groove 51 and the second selection groove 52.

[0092] Referring to Figures 9 to 14 In the automatic shift mode, the end of the mode switching lever 40 is inserted into the first selection groove 51. In this state, when the ball cover 20 is rotated in the selection direction, the end of the mode switching lever 40 moves along the first selection groove 51.

[0093] Referring to Figures 15 to 19 In the manual shift mode, the end of the mode switching lever 40 is inserted into the second selection groove 52. In this state, when the ball cover 20 is rotated in the selection direction, the end of the mode switching lever 40 moves along the second selection groove 52.

[0094] When the mode switching guide 50 is moved in the shift direction by the operation of the mode switching solenoid 110, the mode switching guide 50 can be moved in a state in which the other end of the mode switching lever 40 is inserted into the connection groove 53, and the other end of the mode switching lever 40 can be located in the first selection groove 51 or in the second selection groove 52 by the movement of the mode switching guide 50 in the shift direction.

[0095] Referring to Figures 9 to 14 In the automatic shift mode, the first selection groove 51 in which the mode switching lever 40 is located can include a null position A1 connected to the connection groove 53 and an M (manual) position A2 spaced apart from the null position A1 in one direction. When the ball cover 20 is rotated in the selection direction, the mode switching lever 40 can be moved between the null position A1 and the M position A2 and stopped at the null position A1 or the M position A2.

[0096] That is, in the automatic shifting mode, the initial position A1 and the M position A2 can be fixed ends at which the mode switching lever 40 is fixed.

[0097] The locking protrusion 54 can protrude between the initial position A1 and the M position A2. When the mode switching lever 40 climbs over the locking protrusion 54, an operation force is generated. When the mode switching lever 40 is positioned at the initial position A1 or the M position A2, movement of the mode switching lever 40 can be restricted by the locking protrusion 54, and the position of the mode switching lever 40 can be stopped.

[0098] Referring to Figure 15 , Figure 16 , Figure 17 , Figure 18 and Figure 19 , in the manual shifting mode, the second selection groove 52 at which the mode switching lever 40 is positioned can include an initial position (N range, neutral, 3 / 4 range selection position) B1 connected to the connection groove 53, a 5 / 6 range selection position B2 spaced apart from the initial position B1 in one direction, and a 1 / 2 range selection position B3 and an R range selection position B4 spaced apart from the initial position B1 in the other direction.

[0099] When the ball cover 20 is rotated in the selection direction by the operation of the shift lever 10, the mode switching lever 40 can move between the 5 / 6 range selection position B2 and the R range selection position B4. When the operation force of the driver is released from the shift lever 10, the mode switching lever 40 can return to the initial position B1 by the spring force.

[0100] That is, in the manual shifting mode, the 5 / 6 range selection position B2, the 1 / 2 range selection position B3, and the R range selection position B4 are not fixed ends at which movement of the mode switching lever 40 is fixed, so that when the operation force of the driver is removed after the selection position B2, B3, or B4, the mode switching lever 40 returns to the initial position B1 by the spring force.

[0101] The locking protrusion 54 is provided in the first selection groove 51. Therefore, in the automatic shifting mode, when the mode switching lever 40 is moved from the initial position A1 to the M position A2 by the selection manipulation of the shift lever 10, a large operation force is generated since the mode switching lever 40 climbs over the locking protrusion 54.

[0102] On the contrary, in the second selection groove 52, no protrusion similar to the locking protrusion 54 of the first selection groove 51 is provided. Therefore, in the manual shifting mode, when the shift lever 10 performs the selection manipulation, the mode switching lever 40 can easily move along the second selection groove 52 without any interference.

[0103] Thus, with the use of the locking protrusion 54, the selection operation force of the shift lever 10 in the automatic shift mode can be greater than the selection operation force of the shift lever 10 in the manual shift mode, and thus is easily recognized by the driver.

[0104] The electronic shift operation apparatus according to the present disclosure can include a guide tube 130 coupled to the other end of the hinge shaft 30 and configured to be movable in the longitudinal direction of the hinge shaft 30, a roller shaft 150 coupled to the guide tube 130 with the end of the guide tube 130 penetrated in the shift direction, and selection rollers 140 rotatably coupled to both opposite ends of the roller shaft 150, and a selection stop bracket 170 fixedly coupled to the other side of the ball cover bracket 60 and having selection stop grooves 160 each of which one surface is in contact with the selection rollers 140. The selection rollers 140 can move along the selection stop grooves 160 when the ball cover 20 is rotated in the selection direction.

[0105] The guide tube 130 and the roller shaft 150 can be integrally coupled. Alternatively, the roller shaft 150 can have a structure coupled to be rotatable with respect to the guide tube 130.

[0106] First side grooves 61 can be respectively formed on both opposite side surfaces of the ball cover bracket 60 directed in the selection direction. A mode switching guide bracket 90 and the selection stop bracket 170 can be respectively fixedly coupled to the side surface and the other side surface of the ball cover bracket 60 on which the first side grooves 61 are formed.

[0107] One end of the guide tube 130 is inserted into the other end of the hinge shaft 30, so that the guide tube 130 is installed and configured to be movable in the longitudinal direction of the hinge shaft 30. The roller shaft 150 is integrally coupled to the other end of the guide tube 130 and penetrates the other end of the guide tube 130 in the shift direction. The selection rollers 140 are rotatably coupled to both opposite ends of the roller shaft 150.

[0108] The selection rollers 140 can be installed to be in contact with the selection stop grooves 160 formed in the selection stop bracket 170. The selection rollers 140 can move along the selection stop grooves 160 when the ball cover 20 is rotated in the selection direction.

[0109] Referring to Figure 25 , the selection stop grooves 160 can include a first groove 161, a second groove 162 positioned to be spaced apart from the first groove 161 in one direction, and a third groove 163 and a fourth groove 164 positioned to be spaced apart from the first groove 161 in the other direction.

[0110] The second groove 162 spaced apart from the first groove 161 in one direction and the third groove 163 and the fourth groove 164 spaced apart from the first groove 161 in the other direction can define movement paths each having a schematic arc shape.

[0111] That is, an arc shape can be formed such that, based on the center of the ball cover 20, the radius of the first groove 161 is the shortest, the radius of the second groove 162 and the third groove 163 is longer than that of the first groove 161, and the radius of the fourth groove 164 is longer than that of the third groove 163.

[0112] Referring to Figure 11 and Figure 25 In the automatic shifting mode in which the mode switching lever 40 is positioned in the first selection groove 51, when the mode switching lever 40 is positioned in the initial position A1, the selection roller 140 can be positioned in the first groove 161, and when the mode switching lever 40 is positioned in the M position A2, the selection roller 140 can be positioned in the third groove 163.

[0113] Further, referring to Figure 16 and Figure 25 In the manual shifting mode in which the mode switching lever 40 is positioned in the second selection groove 52, when the mode switching lever 40 is positioned in the initial position B1, the selection roller 140 can be positioned in the first groove 161, when the mode switching lever 40 is positioned in the 1 / 2 range selection position B3, the selection roller 140 can be positioned in the third groove 163, when the mode switching lever 40 is positioned in the R range selection position B4, the selection roller 140 can be positioned in the fourth groove 164, and when the mode switching lever 40 is positioned in the 5 / 6 range selection position B2, the selection roller 140 can be positioned in the second groove 162.

[0114] The electronic shifting operation apparatus according to the present disclosure can further include a second spring fixing pin 180 coupled to penetrate a midpoint of the hinge shaft 30 based on a longitudinal direction, and a selection spring 190 of which both opposite ends are connected to the second spring fixing pin 180 and the roller shaft 150, and the selection spring 190 is configured to provide an elastic force of the roller shaft 150.

[0115] The second spring fixing pin 180 can be coupled to penetrate the midpoint of the hinge shaft 30 based on the longitudinal direction in the shifting direction. The first spring fixing pin 70 and the second spring fixing pin 180 can be spaced left and right from the midpoint of the hinge shaft 30 based on the longitudinal direction and installed in parallel with the midpoint of the hinge shaft 30 based on the longitudinal direction.

[0116] The selection spring 190 can be configured as a coil spring and provide a spring force that pulls the roller shaft 150 toward the inside of the hinge shaft 30. Accordingly, the selection roller 140 can always be kept in contact with the selection stop groove 160 by the spring force of the selection spring 190.

[0117] When the selection roller 140 moves to the second groove 162, the third groove 163, or the fourth groove 164 as the ball cover 20 rotates in the selection direction in a state in which the selection roller 140 is located in the first groove 161, the selection spring 190 can generate an operation force when being stretched by a phase difference through the selection stop groove 160, and the guide tube 130 can move the selection spring 190 stretched range from the hinge shaft 30, so that the degree of protrusion of the guide tube 130 from the hinge shaft 30 can be increased.

[0118] The electronic shift operation apparatus according to the present disclosure can further include a pattern guide pin 200 fixedly coupled to the ball cover 20, protruding downward and penetrating the ball cover bracket 60, and a pattern bracket 220 fixedly coupled to a bottom surface of the ball cover bracket 60 and having a pattern guide rail 210 configured to guide movement of the pattern guide pin 200 in the selection direction and the shift direction.

[0119] The pattern guide pin 200 can be connected to a central portion of a lower portion of the ball cover 20, and can rotate integrally with the ball cover 20 when the ball cover 20 rotates in the selection direction and the shift direction.

[0120] A lower end of the pattern guide pin 200 can be inserted into the pattern guide rail 210, so that the pattern guide pin 200 can move along the pattern guide rail 210 when the ball cover 20 rotates in the selection direction and the shift direction.

[0121] Referring to Figure 27 and Figure 28 , the pattern guide rail 210 can include a selection rail 211 configured to guide movement of the pattern guide pin 200 in the selection direction, and a shift rail 212 configured to guide movement of the pattern guide pin 200 in the shift direction.

[0122] Figure 27 and Figure 28 show states in which the pattern guide pin 200 moves along the pattern guide rail 210 in the selection direction and the shift direction in the automatic shift mode and the manual shift mode.

[0123] Referring to Figure 11 , in the automatic shift mode, the mode switching lever 40 is located in the first selection groove 51, the mode switching lever 40 moves between the M position A2 and the initial position A1 which is a Null position during the selection manipulation, and the mode switching lever 40 cannot perform selection movement to the 5 / 6 shift selection position B2 and the R shift selection position B4 based on the manual shift mode.

[0124] Therefore, in the automatic shift mode, movement of the pattern guide pin 200 in the selection direction is limited to the initial position A1 and the M position A2.

[0125] On the contrary, referring toFigure 16 In the manual shifting mode, the mode switching lever 40 is positioned in the second selection groove 52, and during the selection operation, the mode switching lever 40 can be moved along all selection paths from the initial position B1 as a neutral (N) position to the 5 / 6 selection position B2 in one direction and the 1 / 2 selection position B3 and the R selection position B4 in the other direction.

[0126] Accordingly, in the manual shifting mode, the pattern guide pin 200 can be moved in the selection direction along all selection paths without being restricted.

[0127] In the automatic shifting mode, the initial position A1 can correspond to a Null position, in the manual shifting mode, the initial position B1 can correspond to an N position, a neutral, or a 3 / 4 selection position, and the initial position A1 in the automatic shifting mode and the initial position B1 in the manual shifting mode can be the same position.

[0128] Further, the M position A2 in the automatic shifting mode can be the 1 / 2 selection position B3 in the manual shifting mode.

[0129] According to the present disclosure, the shift direction stroke can be differently restricted in the automatic shifting mode and the manual shifting mode. This can be performed by a shift direction stroke restricting device which will be described below.

[0130] The shift direction stroke is relatively shorter in the automatic shifting mode than in the manual shifting mode, which can improve the operation convenience.

[0131] On the contrary, the shift direction stroke is relatively longer in the manual shifting mode than in the automatic shifting mode, which can improve the recognition performance during the shift operation.

[0132] As described above, the shift direction stroke in the automatic shifting mode and the shift direction stroke in the manual shifting mode can be the same as the shift direction stroke during the shift operation of the automatic transmission vehicle and the manual transmission vehicle in the related art, which can eliminate the heterogeneity of the vehicles in the related art.

[0133] The electronic shift operation apparatus according to the present disclosure can further include a permanent magnet 230 fixedly coupled to the ball cover 20, and a printed circuit board (PCB) 240 fixed to the ball cover bracket 60 to face the permanent magnet 230, and configured to output a selected shift position by identifying a magnetic flux signal according to a position change of the permanent magnet 230 when the ball cover 20 is rotated in the selection direction and the shift direction.

[0134] The mode switching guide bracket 90 is coupled to a side surface of the ball cover bracket 60, the PCB 240 is fixedly coupled to a side surface of the ball cover bracket 60 spaced apart at a right angle from the mode switching guide bracket 90, and the permanent magnet 230 is coupled to the ball cover 20 to face the PCB 240.

[0135] The PCB 240 has a Hall sensor configured to detect the permanent magnet 230, so that the PCB 240 can recognize and output a selection position and a selected shift position signal when the position of the permanent magnet 230 changes according to the rotation of the ball cover 20 in the selection direction and the shift direction.

[0136] The electronic shift operation apparatus according to the present disclosure can further include a shifter controller 260 fixed to the ball cover bracket 60, configured to transmit the shift position signal output from the PCB 240 to the vehicle controller 250, and configured to control the operation of the mode switching solenoid 110 by receiving a signal of the mode selection part 120, the signal of the mode selection part 120 can select an automatic shift mode and a manual shift mode.

[0137] The shifter controller 260 can be located on a side of the PCB 240, the PCB 240 and the shifter controller 260 are electrically connected to receive a signal, and the shifter controller 260 including the PCB 240 can be covered and protected by a controller cover 270.

[0138] The controller cover 270 can be fixedly coupled to a side surface of the ball cover bracket 60.

[0139] Referring to Figure 42 The automatic shift mode signal or the manual shift mode signal generated by the manipulation of the mode selection part 120 is transmitted to the shifter controller 260, and the shifter controller 260 can control the operation of the mode switching solenoid 110 by using the automatic shift mode signal or the manual shift mode signal.

[0140] Further, the shift position signal selected by the selection rotation and the shift rotation of the ball cover 20 can be output through the PCB 240, and then transmitted to the vehicle controller 250 through the shifter controller 260, and the operation of the vehicle driving part 280 can be controlled by the vehicle controller 250.

[0141] An electronic shift operation apparatus according to the present disclosure can include a mode selection portion 120 configured to select an automatic shift mode or a manual shift mode, a mode switch lever 40 configured to be connected to a shift lever 10, and a mode switch guide 50 having a first selection groove 51 and a second selection groove 52 configured to guide movement of the mode switch lever 40 in a selection direction, and a connection groove 53 configured to connect the first selection groove 51 and the second selection groove 52. When an automatic shift mode signal is generated or a manual shift mode signal is generated by manipulation of the mode selection portion 120, the mode switch guide 50 is moved in a shift direction by operation of a mode switch solenoid 110. When the mode switch guide 50 is moved in the shift direction, the mode switch guide 50 is moved in a state in which the mode switch lever 40 is inserted into the connection groove 53, so that the mode switch lever 40 can be located in the first selection groove 51 or in the second selection groove 52.

[0142] In the automatic shift mode, the mode switch lever 40 can be located in the first selection groove 51 and moved along the first selection groove 51 to an initial position Al or an M position A2 by manipulation of the shift lever 10 in the selection direction.

[0143] In the automatic shift mode, the initial position Al can be a Null position.

[0144] Further, in the manual shift mode, the mode switch lever 40 can be located in the second selection groove 52 and moved along the second selection groove 52 to any one of an initial position Bl, a 5 / 6 range selection position B2, a 1 / 2 range selection position B3, and an R range selection position B4 by manipulation of the shift lever 10 in the selection direction.

[0145] In the manual shift mode, the initial position Bl can be an N range, a Neutral position, and a 3 / 4 range selection position.

[0146] Next, a stroke limiting device capable of limiting a shift direction stroke of a shift lever differently according to an automatic shift mode and a manual shift mode will be described.

[0147] An electronic shift operation apparatus according to the present disclosure can include a mode selection portion 120 configured to select an automatic shift mode or a manual shift mode, and a shift lever 10 manipulated by a driver in a selection direction and a shift direction. In the automatic shift mode and the manual shift mode, a shift direction stroke of the shift lever 10 can be limited differently.

[0148] That is, compared to the manual shift mode, in the automatic shift mode, the shift direction stroke can be limited to a relatively short length, which can improve operation convenience.

[0149] In contrast, the shift direction stroke is limited to be relatively longer in the manual shift mode than in the automatic shift mode, which can improve the recognition performance during the shift operation.

[0150] As described above, the shift direction stroke in the automatic shift mode and the shift direction stroke in the manual shift mode can be the same as the shift direction strokes during the shift operation of the automatic transmission vehicle and the manual transmission vehicle in the related art, which can eliminate the heterogeneity of the vehicles in the related art.

[0151] To implement this configuration, the electronic shift operation apparatus according to the disclosure can include a ball cover 20 coupled to the shift lever 10 and configured to rotate in a selection direction and a shift direction when the driver manipulates the shift lever 10, a shift stop pin 290 coupled to the ball cover 20 and configured to rotate together with the ball cover 20 when the shift lever 10 is manipulated in the shift direction, and a shift stopper 320 having a shift stop groove 310 configured to be in contact with the shift stop pin 290. The shift stop pin 290 can move along the shift stop groove 310 when the shift lever 10 is manipulated in the shift direction.

[0152] The shift stop pin 290 can be fixedly coupled to a position of the ball cover 20 directed to the shift direction.

[0153] In more detail, the permanent magnet 230 can be fixedly coupled to one side of the ball cover 20 directed to the shift direction, and the shift stop pin 290 can be fixedly coupled to the other side directed to the shift direction.

[0154] The permanent magnet 230 and the shift stop pin 290 can be coupled to the ball cover 20 so as to be directed in opposite directions.

[0155] The shift stop pin 290 can have a boss portion 291, and the boss portion 291 of the shift stop pin 290 can be fixedly coupled to the ball cover 20.

[0156] The shift stopper 320 can be located on one side of the shift stop pin 290 based on the shift direction. The shift stop groove 310 can be formed in one surface of the shift stopper 320, and an end portion of the shift stop pin 290 can have a structure that is always in contact with the shift stop groove 310.

[0157] When the ball cover 20 rotates in the shift direction as the driver manipulates the shift lever 10, the shift stop pin 290 can move along the shift stop groove 310 in a state in which the shift stop pin 290 is in contact with the shift stop groove 310.

[0158] The stroke of the shift stop pin 290 moving along the shift stop groove 310 can be relatively shorter in the automatic shift mode than in the manual shift mode, and can be relatively longer in the manual shift mode than in the automatic shift mode.

[0159] According to the present disclosure, a second side groove 62 can be formed in one surface of the ball cover bracket 60 based on the shift direction, and a boss portion 291 of the shift stopper pin 290 can be inserted and mounted into the second side groove 62. When the shift lever 10 is manipulated in the shift direction, the boss portion 291 of the shift stopper pin 290 contacts one end or the other end of the second side groove 62, and the full stroke in the shift direction can be limited.

[0160] When the ball cover 20 is rotated in the shift direction by manipulation of the shift lever 10, the ball cover 20, the shift stopper pin 290, and the boss portion 291 can rotate together in the shift direction, and in the illustrated state, the second side groove 62 can extend upward and downward from the side surface of the ball cover bracket 60 to guide the rotation of the boss portion 291 in the shift direction.

[0161] When the boss portion 291 of the shift stopper pin 290 contacts the upper end or the lower end of the second side groove 62 as the ball cover 20 is rotated in the shift direction, the rotation in the shift direction can be limited.

[0162] The electronic shift operation apparatus according to the present disclosure can further include a shift stopper bracket 330 fixedly coupled to one side of the ball cover bracket 60 based on the shift direction, a shift stopper 320 inserted into the shift stopper bracket 330 and mounted to be movable in the shift direction, a shift spring 340 both opposite ends of which are connected to the shift stopper bracket 330 and the shift stopper 320, and the shift spring 340 is configured to provide an elastic force for the movement of the shift stopper 320, a shift solenoid 350 fixedly coupled to the shift stopper bracket 330 and configured to be operated by receiving an automatic shift mode signal or a manual shift mode signal, and a stroke limiter 360 coupled to the shift solenoid 350 and configured to move away from or toward the shift stopper 320 when the shift solenoid 350 is operated, the stroke limiter 360 is configured to differently limit the shift direction stroke of the shift stopper 320 based on the position of the movement.

[0163] The shift stopper bracket 330 can be fixedly coupled to the side surface of the ball cover bracket 60 in which the second side groove 62 is formed. The shift stopper 320 can be inserted into the shift stopper bracket 330 and mounted and configured to be movable in the shift direction.

[0164] When the ball cover 20 is rotated in the shift direction as the driver manipulates the shift lever 10, the shift detent 290 can move along the shift detent groove 310 in a state in which the shift detent 290 is in contact with the shift detent groove 310. When the shift detent 290 moves, the shift detent 320 can move in the shift direction in a state in which the shift detent 320 is inserted into the shift detent bracket 330 by the phase difference of the shift detent groove 310.

[0165] The shift spring 340 can be configured as a coil spring. Both opposite ends of the shift spring 340 can be mounted to be supported by the shift detent 320 and the shift detent bracket 330, and the shift spring 340 can provide a spring force that moves the shift detent 320 toward the ball cover 20.

[0166] The shift solenoid 350 can be fixedly coupled to the shift detent bracket 330, and the stroke limiter 360 can be coupled to the shift solenoid 350, so that the stroke limiter 360 can move upward or downward when the shift solenoid 350 is operated.

[0167] The solenoid cover 370 can be coupled to the shift detent bracket 330, and the shift solenoid 350 and the stroke limiter 360 can be covered and protected by the solenoid cover 370.

[0168] When the driver manipulates the mode selection portion 120, an automatic shift mode signal or a manual shift mode signal can be generated. The automatic shift mode signal or the manual shift mode signal can be transmitted to the shifter controller 260. The shifter controller 260 can control the operation of the shift solenoid 350 by using the automatic shift mode signal or the manual shift mode signal and an operation signal of the clutch pedal 380. The stroke limiter 360 can move upward or downward by the operation of the shift solenoid 350.

[0169] When the automatic shift mode signal is generated, the stroke limiter 360 can be fixed in a state in which the stroke limiter 360 moves to an upper side in which the shift detent 320 is present. When the manual shift mode signal and the operation signal of the clutch pedal 380 are generated together, the stroke limiter 360 can be fixed in a state in which the stroke limiter 360 moves to a lower side away from the shift detent 320. When the manual shift mode signal is generated without the operation signal of the clutch pedal 380, the stroke limiter 360 can be fixed in a state in which the stroke limiter 360 moves to the upper side.

[0170] The shifter controller 260 can control the operation of the mode switching solenoid 110 by using the automatic shift mode signal or the manual shift mode signal generated by the manipulation of the mode selection portion 120.

[0171] Further, the shifter controller 260 can control the operation of the shift solenoid 350 by using the automatic shift mode signal or the manual shift mode signal generated by the manipulation of the mode selection portion 120.

[0172] When the automatic shift mode signal is generated by the manipulation of the mode selection portion 120 in a vehicle not equipped with a clutch pedal (for example, a two-pedal vehicle), the shifter controller 260 can control the stroke limiter 360 so that the stroke limiter 360 is fixed in a state in which the stroke limiter 360 moves to the upper side in which the shift stopper 320 is present. When the manual shift mode signal is generated by the manipulation of the mode selection portion 120, the shifter controller 260 can control the stroke limiter 360 so that the stroke limiter 360 is fixed in a state in which the stroke limiter 360 moves to the lower side away from the shift stopper 320.

[0173] A plurality of guide protrusions 321 and a plurality of guide grooves 331 for guiding the movement of the shift stopper 320 in the shift direction can be formed in the shift stopper 320 and the shift stopper bracket 330, and the plurality of guide protrusions 321 and the plurality of guide grooves 331 are coupled to each other.

[0174] The plurality of guide protrusions 321 can be formed on the outer circumferential surface of the shift stopper 320 and spaced apart from each other. The guide grooves 331 equal in number to the guide protrusions 321 can be formed on the inner circumferential surface of the shift stopper bracket 330 and disposed at portions matching the guide protrusions 321.

[0175] The guide protrusions 321 and the guide grooves 331 can extend in the shift direction in which the shift stopper 320 moves.

[0176] Referring to Figures 34 to 35 , the shift stopper groove 310 can include an inner groove 311 formed as a recess in a central portion of one surface of the shift stopper 320, an outer groove 312 formed as a recess outside the inner groove 311 and connected to the inner groove 311 in the circumferential direction, and a protrusion portion 313 formed between the inner groove 311 and the outer groove 312 to connect the inner groove 311 and the outer groove 312, the protrusion portion 313 having a cross-section protruding from the inner groove 311 and the outer groove 312 and connected to the inner groove 311 and the outer groove 312 in the circumferential direction.

[0177] Referring to Figure 35 , Figure 36 and Figure 37A stop groove 322 is formed in a side edge portion of the bottom surface of the shift stopper 320, and an upper end of the stroke limiter 360 is inserted into the stop groove 322 in the case of the automatic shift mode. In the case of the automatic shift mode, when the shift stopper 320 is moved in the shift direction by manipulation of the shift lever 10 in the shift direction, the movement of the shift stopper 320 in the shift direction can be limited at the point in time when a side wall of the stop groove 322 comes into contact with a side surface of the stroke limiter 360.

[0178] When the automatic shift mode signal is generated by manipulation of the mode selection portion 120, the shift lever controller 260 can control the operation of the shift solenoid 350 so that the stroke limiter 360 is in a state of being inserted into the stop groove 322.

[0179] Figure 35 A state in which the shift stopper 320 is located in the inner groove 311 in the case of the automatic shift mode is shown, Figures 36 to 37 A state in which the shift lever 10 is rotated in the shift direction from the state in which the shift stopper 320 is located in the inner groove 311 is shown. Figure 35 A state in which the shift lever 10 is rotated in the shift direction from the state in which the shift stopper 320 is located in the inner groove 311 is shown.

[0180] As shown in FIG. 6, when the shift stopper 290 is located in the inner groove 311 in the case of the automatic shift mode, the position of the shift lever 10 can be fixed to the initial position (Null) Al or the M (manual) position A2. Figure 35

[0181] A state in which the shift lever 10 is rotated in the shift direction from the state in which the shift stopper 320 is located in the inner groove 311 is shown. Figure 36 A state in which the shift lever 10 is rotated in the shift direction from the state in which the shift stopper 320 is located in the inner groove 311 is shown. Figure 37 Figure 35 When the ball cover 20 is rotated by rotation of the shift lever 10 in the shift direction, the shift stopper 290 is moved from the inner groove 311 toward the outer groove 312 in a state in which the shift stopper 290 is in contact with the shift stopper groove 310, and the shift stopper 320 is moved to the left by the movement of the shift stopper 290. In this case, the shift spring 340 is compressed.

[0182] The movement of the shift stopper 320 in the shift direction is limited at the point in time when a side wall of the stop groove 322 comes into contact with a side surface of the stroke limiter 360 when the shift stopper 320 is moved to the left. In this case, the shift stopper 290 is located on the protrusion portion 313 of the shift stopper groove 310.

[0183] When the shift stopper 290 is located on the protrusion portion 313, the shift lever 10 can be moved toward any one of the D range, the (-) range (down range), the R range, and the (+) range (up range).

[0184] When the shift stopper 290 is located on the protrusion portion 313, the shift lever 10 can be moved toward any one of the D range, the (-) range (down range), the R range, and the (+) range (up range).

[0185] ​That is, when the shift lever 10 is moved toward any one of the shift positions of D range, (-) range, R range, and (+) range, the shift stop pin 290 can be moved toward the protruding portion 313.

[0186] Further, when the operation force is released in a state where the shift lever 10 is moved to any one of the shift positions of D range, (-) range, R range, and (+) range, the shift stop pin 290 can be returned to the inner groove 311 by the spring force, and the shift lever 10 can be returned to the initial position A1 or the M position A2.

[0187] Referring to Figure 38 , Figure 39 and Figure 40 , in the manual shift mode, when the stroke limiter 360 is lowered by the operation of the shift solenoid 350, the stroke limiter 360 can exit from the stop groove 322 and be spaced apart from the stop groove 322. In the manual shift mode, when the shift stopper 320 is moved in the shift direction by the manipulation of the shift lever 10 in the shift direction, the shift stopper 320 can be moved without being in contact with the stroke limiter 360.

[0188] That is, when the stroke limiter 360 is lowered and deviates from the movement path of the shift stopper 320 based on the shift direction, the shift stopper 320 is not in contact with the stroke limiter 360 when the shift stopper 320 is moved in the shift direction. Accordingly, the shift stopper 320 can be moved by the maximum distance in the shift direction.

[0189] When the manual shift mode signal is generated by the manipulation of the mode selection portion 120, the shifter controller 260 can control the operation of the shift solenoid 350 so that the stroke limiter 360 exits from the stop groove 322 and is spaced apart from the stop groove 322.

[0190] Figure 38 A state in which the shift stop pin 290 is located in the inner groove 311 in the manual shift mode is shown, Figures 39 to 40 a state in which the shift lever 10 is rotated in the shift direction from Figure 38 .

[0191] As shown in Figure 38 , when the shift stop pin 290 is located in the inner groove 311 in the manual shift mode, the shift lever 10 can be located in any one of the initial position (N range, neutral, and 3 / 4 range selection position) B1, the 5 / 6 range selection position B2, the 1 / 2 range selection position B3, and the R range selection position B4.

[0192] When the operation force of the shift lever 10 is released in a state in which the shift lock pin 290 is positioned in any one of the 5 / 6 range selection position B2, the 1 / 2 range selection position B3, and the R range selection position B4, the shift lever 10 can return to the initial position B1 by the spring force.

[0193] Figure 39 and Figure 40 The state in which the shift lever 10 is rotated clockwise and counterclockwise in the shift direction from the state in the Figure 38

[0194] When the ball cover 20 is rotated by the rotation of the shift lever 10 in the shift direction, the shift lock pin 290 moves from the inner groove 311 toward the outer groove 312 in a state in which the shift lock pin 290 is in contact with the shift lock groove 310, and the shift lock 320 is moved to the left by the movement of the shift lock pin 290. In this case, the shift spring 340 is compressed.

[0195] As the shift lock 320 is moved to the left, the shift lock pin 290 passes over the protrusion 313, and the shift lock pin 290 is inserted into the outer groove 312 and then fixed at an appropriate position in the outer groove 312.

[0196] When the shift lock pin 290 is positioned in the outer groove 312, the shift lever 10 can be positioned to be fixed at any one of the 1st, 2nd, 3rd, 4th, 5th, 6th, and R ranges.

[0197] Figure 41 The case in which the manual shift mode signal is generated by the manipulation of the mode selection portion 120, but the operation signal of the clutch pedal 380 is not generated since the driver does not manipulate the clutch pedal 380.

[0198] In this case, the shift lever controller 260 controls the operation of the shift solenoid 350 so that the stroke limiter 360 is in a state of being inserted into the stop groove 322.

[0199] Therefore, when the shift lock 320 is moved in the shift direction by the manipulation of the shift lever 10 in the shift direction, the side wall of the stop groove 322 is in contact with one side surface of the stroke limiter 360 so that the movement of the shift lock 320 in the shift direction is limited, and the operation of the manual shift is no longer performed.

[0200] ​In other words, when a manual shift mode signal is generated but no clutch pedal 380 operation signal is generated, and the driver manipulates the shift lever 10 in the shift direction, the shift stop 320 is allowed to move in the shift direction until the side wall of the stop groove 322 contacts one side surface of the travel limiter 360. When the side wall of the stop groove 322 contacts one side surface of the travel limiter 360, the movement of the shift stop 320 in the shift direction is limited by the travel limiter 360.

[0201] As described above, with the movement of the shift stop 320 in the shift direction restricted by the travel limiter 360, the shift stop pin 290 is located on the protrusion 313, and the movement of the shift stop pin 290 toward the outer groove 312 that outputs the shift position signal is restricted. Therefore, no shift position signal is output, which prevents erroneous operation.

[0202] Furthermore, when the shift stop pin 290 is in the state of being on the protrusion 313, and the operating force of the shift lever 10 is released, the shift stop pin 290 returns to the inner groove 311 by the spring force, and the shift lever 10 returns to the initial position B1.

[0203] The system of the shifting operation device according to this disclosure will be described below.

[0204] The electronic shifting device according to this disclosure may include: a shift lever 10 operable in a selection direction along a selection rail 211 and operable in a shift direction along a plurality of shift rails 212 connected to the selection rail 211; and a mode selection unit 120 capable of selecting an automatic shifting mode or a manual shifting mode. Based on the input to the mode selection unit 120, the mode can be switched to an automatic shifting mode with automatic shifting operation enabled or a manual shifting mode with manual shifting operation enabled. When the shift lever 10 is operated along the selection rail 211 in the selection direction, the movement path of the shift lever 10 can vary depending on whether it is an automatic shifting mode or a manual shifting mode. When the shift lever 10 is operated along the shift rails 212 in the shift direction, the shift direction travel of the shift lever 10 can vary depending on whether it is an automatic shifting mode or a manual shifting mode.

[0205] Furthermore, the electronic shifting operation device according to this disclosure may further include: a mode switching solenoid 110 configured to operate to switch the mode to an automatic shifting mode or a manual shifting mode; and a shifter controller 260 configured to control the operation of the mode switching solenoid 110 by receiving a signal from the mode selection unit 120.

[0206] The shifter controller 260 can control the operation of the mode switching solenoid 110, so that in automatic shifting mode, the movement of the shift lever 10 in the selection direction is restricted to the selection position located at the edge of the selection rail 211.

[0207] Referring to Figure 11 In the automatic shift mode, when the shift lever 10 is manipulated in the selection direction, the selection movement of the shift lever 10 can be limited to the 5 / 6 range selection position and the R range selection position in the manual shift mode.

[0208] The shift knob controller 260 can control the operation of the mode switching solenoid 110 so that the selection operation force when the shift lever 10 is manipulated in the selection direction in the automatic shift mode is higher than the selection operation force when the shift lever 10 is manipulated in the selection direction in the manual shift mode.

[0209] That is, in the automatic shift mode, when the shift lever 10 performs selection manipulation from the initial position A1 to the M position A2, the operation force is generated as the mode switching lever 40 climbs over the locking protrusion 54, and the selection operation force in the automatic shift mode is higher than that in the manual shift mode by the locking protrusion 54. Accordingly, the recognition performance of the driver can be improved.

[0210] Referring to Figure 12 and Figure 14 In the automatic shift mode, when the mode switching lever 40 is located at the M position A2 by selection manipulation of the shift lever 10, the position of the mode switching lever 40 is fixed at the M position A2 by the locking protrusion 54, and the movement of the shift lever 10 can be stopped.

[0211] The electronic shift operation apparatus according to the present disclosure can further include a shift solenoid 350 configured to be operated by being controlled by the shift knob controller 260 and to differently limit the shift direction stroke of the shift lever 10 according to the automatic shift mode and the manual shift mode.

[0212] The shift knob controller 260 can control the operation of the shift solenoid 350 to limit the shift direction stroke of the shift lever 10 to be relatively shorter in the automatic shift mode than in the manual shift mode.

[0213] Referring to Figure 27 and Figure 28 The shift direction stroke of the shift lever 10 can be limited to be relatively shorter in the automatic shift mode than in the manual shift mode and to be relatively longer in the manual shift mode than in the automatic shift mode.

[0214] According to the present disclosure, in the automatic shift mode, the end of the shift rail 212 is defined as a non-fixed end, the shift lever 10 located at the initial position A1 or the M position A2 is manipulated in the shift direction, and then the operation force is eliminated so that the shift lever 10 can be returned to the initial position A1 or the M position A2 by the spring force.

[0215] In the automatic shift mode, the initial position A1 can be a Null position.

[0216] Further, in the manual shift mode, the shift lever 10 performs a selection operation to the 5 / 6th gear selection position B2, the 1 / 2nd gear selection position B3, or the R gear selection position B4, and then the operation force is canceled so that the shift lever 10 can return to the initial position B1.

[0217] In the manual shift mode, the initial position B1 can be the N gear, the neutral, and the 3 / 4th gear selection position.

[0218] In the manual shift mode, the end portion of the shift rail 212 is defined as a fixed end portion, the shift lever 10 is manipulated in the shift direction, and then the operation force is canceled so that the shift lever 10 can be fixed to any one of the 1st gear, the 2nd gear, the 3rd gear, the 4th gear, the 5th gear, the 6th gear, and the R gear.

[0219] According to the present disclosure, the shifter controller 260 can receive an operation signal of the clutch pedal 380. When an automatic shift mode signal is input by manipulation of the mode selection portion 120, the shifter controller 260 can control the operation of the shift solenoid 350 so that the shift lever 10 is allowed to move in the shift direction to a target shift position (the D gear, the R gear, the (+) gear, or the (-) gear) regardless of the operation signal of the clutch pedal 380.

[0220] Further, the shifter controller 260 can control the operation of the shift solenoid 350 so that the shift lever 10 is allowed to move in the shift direction to a target shift position (the 1st gear, the 2nd gear, the 3rd gear, the 4th gear, the 5th gear, the 6th gear, or the R gear) only in a state where a manual shift mode signal is input by manipulation of the mode selection portion 120.

[0221] Further, when a manual shift mode signal is input to the shifter controller 260 by manipulation of the mode selection portion 120 and the operation signal of the clutch pedal 380 is not input, the shifter controller 260 can control the operation of the shift solenoid 350 to restrict the movement of the shift lever 10 in the shift direction so that the shift lever 10 cannot move to a target shift position (the 1st gear, the 2nd gear, the 3rd gear, the 4th gear, the 5th gear, the 6th gear, or the R gear).

[0222] When the automatic shift mode signal is generated by the manipulation of the mode selection portion 120 in a vehicle not equipped with a clutch pedal (e.g., a two-pedal vehicle), the shift lever controller 260 can control the stroke limiter 360 so that the stroke limiter 360 is fixed in a state in which the stroke limiter 360 moves to an upper side in which the shift stopper 320 is present. When the manual shift mode signal is generated by the manipulation of the mode selection portion 120, the shift lever controller 260 can control the stroke limiter 360 so that the stroke limiter 360 is fixed in a state in which the stroke limiter 360 moves to a lower side away from the shift stopper 320.

[0223] In the manual shift mode, the shift lever controller 260 can control the operation of the mode switching solenoid 110 so that the shift lever 10 moves to a plurality of selection positions positioned along the selection rail 211 by the manipulation of the shift lever 10 in the selection direction. In the automatic shift mode, the shift lever controller 260 can control the operation of the mode switching solenoid 110 to limit the shift lever 10 from moving to any one or more of the plurality of selection positions positioned along the selection rail 211.

[0224] In the automatic shift mode, the route along which the shift lever 10 can move along the selection rail 211 by the operation of the mode switching solenoid 110 can be limited to be relatively shorter than the route along which the shift lever 10 can move along the selection rail 211 in the manual shift mode.

[0225] In the manual shift mode, the plurality of selection positions can include an initial position B1 to which the shift lever 10 returns by the spring force when the operation force of the shift lever 10 in the selection direction is released, a 5 / 6 shift selection position B2 positioned in one direction from the initial position B1 along the selection rail 211 so that the 5th gear or the 6th gear can be selected by the manipulation of the shift lever 10 in the shift direction, a 1 / 2 shift selection position B3 positioned in another direction from the initial position B1 along the selection rail 211 so that the 1st gear or the 2nd gear can be selected by the manipulation of the shift lever 10 in the shift direction, and an R shift selection position B4 positioned at an edge in another direction from the initial position B1 along the selection rail 211 so that the R gear can be selected by the manipulation of the shift lever 10 in the shift direction. The initial position B1 can be a 3 / 4 shift selection position B1 in which the 3rd gear or the 4th gear can be selected by the manipulation of the shift lever 10 in the shift direction.

[0226] In the automatic shift mode, one of the two selection positions can be alternately selected by manipulation of the shift lever 10 in the selection direction. The two selection positions can include an initial position A1 at which R range or D range can be selected by manipulation of the shift lever 10 in the shift direction, and an M position A2 positioned in another direction from the initial position A1 along the selection rail 211 so that (+) range (upshift) or (−) range (downshift) can be selected by manipulation of the shift lever 10 in the shift direction.

[0227] In the automatic shift mode, the initial position A1 is the same position as the initial position B1 in the manual shift mode, and the M position A2 in the automatic shift mode can be the same position as the 1 / 2 range selection position B3 in the manual shift mode.

[0228] In the automatic shift mode, the selection position of the shift lever 10 is fixed so that movement in the selection direction is stopped at the M position A2, and the shift lever 10 does not return to the initial position A1 even if the operating force is eliminated at the M position A2.

[0229] The electronic shift operation apparatus according to the present disclosure can further include a PCB 240 configured to sense and output a shift position selected by manipulation of the shift lever 10 in the selection direction and in the shift direction, and the shifter controller 260 can transmit a shift position signal output from the PCB 240 to the vehicle controller 250, and the driving portion 280 can be operated by receiving a signal of the vehicle controller 250.

[0230] Further, the shifter controller 260 can receive RPM information of the vehicle through signals of the accelerator pedal 390 and the brake pedal 400.

[0231] As described above, the electronic shift operation apparatus according to the present disclosure can switch the mode of shift operation to automatic shift or manual shift based on the intention of the driver. Accordingly, the simplicity of shift operation can be eliminated, which can provide pleasure to the driver and improve marketability.

[0232] Further, the electronic shift operation apparatus according to the present disclosure can limit the shift direction stroke of the shift lever 10 to different lengths according to the automatic shift mode and the manual shift mode, thereby improving the convenience of manipulation and improving recognition performance during shift operation.

[0233] While specific embodiments of the present disclosure have been illustrated and described, it will be apparent to those skilled in the art that various modifications and changes can be made without departing from the technical spirit of the present disclosure defined in the appended claims.
