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 a shift operation to a manual shift and an automatic shift according to an intention of a driver and limiting a shift direction stroke of a shift lever differently according to the automatic shift mode and the manual shift mode. 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 shift intention of a driver to the TCU as an electric signal. In addition, the shift mechanism can be miniaturized, which can secure a large space between a driver seat and a passenger 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

[0007] The present disclosure is proposed to solve the problems, and aims to provide an electronic shift operation apparatus capable of limiting a shift direction stroke of a shift lever differently according to an automatic shift mode and a manual shift mode, thereby improving recognition performance of a shift operation in the automatic shift mode or the manual shift mode and improving marketability.

[0008] To achieve the above object, the present disclosure provides an electronic shift operation apparatus including a mode selection section configured to select an automatic shift mode or a manual shift mode, and a shift lever configured to be manipulated by a driver in a selection direction and a shift direction, wherein a shift direction stroke of the shift lever is differently limited in the automatic shift mode and the manual shift mode.

[0009] The shift direction stroke of the shift lever 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.

[0010] The electronic shift operation apparatus can include a ball cover coupled to the shift lever and configured to rotate in the selection direction and the shift direction when the shift lever is manipulated by the driver, a shift stop pin coupled to the ball cover and configured to rotate with the ball cover when the shift lever is manipulated in the shift direction, and a shift stopper having a shift stop groove configured to be in contact with the shift stop pin, wherein the shift stop pin moves along the shift stop groove when the shift lever is manipulated in the shift direction.

[0011] The shift direction stroke of the shift lever 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.

[0012] The electronic shift operation apparatus can further include a ball cover support configured to cover the ball cover and guide rotation of the ball cover in the selection direction and the shift direction.

[0013] A second side groove is formed in one surface of the ball cover support based on the shift direction, wherein the boss portion of the shift stop pin is inserted and installed into the second side groove, and wherein, in the case where the shift lever is manipulated in the shift direction, a full stroke in the shift direction is limited when the boss portion of the shift stop pin is in contact with one end or the other end of the second side groove.

[0015] The electronic shift operation apparatus can further include a shifter controller fixed to the ball cover bracket and configured to control operation of the shift solenoid by receiving a signal of the mode selection part and a signal of the clutch pedal.

[0016] A plurality of guide protrusions and a plurality of guide grooves coupled to each other can be formed on the shift stopper and the shift stopper bracket, and the plurality of guide protrusions and the plurality of guide grooves can guide movement of the shift stopper in the shift direction.

[0017] The shift stopper groove can include an inner groove formed as a recess in a central portion of one surface of the shift stopper, an outer groove formed as a recess outside the inner groove and connected to the inner groove in a circumferential direction, and a protrusion portion formed between the inner groove and the outer groove to connect the inner groove and the outer groove, the protrusion portion having a cross section protruding from and connected to the inner groove and the outer groove in the circumferential direction.

[0018] A stop groove is formed in a side edge portion of a bottom surface of the shift stopper, wherein one side of an upper end of the stroke limiter is inserted into the stop groove in the case of the automatic shift mode, and wherein, in the case of the automatic shift mode, when the shift stopper is moved in the shift direction by manipulation of the shift lever in the shift direction, movement of the shift stopper in the shift direction is limited at a point in time at which a side wall of the stop groove comes into contact with one side surface of the stroke limiter.

[0019] When the automatic shift mode signal is generated by manipulation of the mode selection part, the shifter controller controls operation of the shift solenoid so that the stroke limiter is in a state of being inserted into the stop groove.

[0020] A stop groove is formed in a side edge portion of the bottom surface of the shift stopper, wherein, in the case of the manual shift mode, when the stroke limiter is lowered by the operation of the shift solenoid, the stroke limiter exits from the stop groove and is spaced apart from the stop groove, and wherein, in the case of the manual shift mode, when the shift stopper is moved in the shift direction by the manipulation of the shift lever in the shift direction, the shift stopper is moved without coming into contact with the stroke limiter.

[0021] A stop groove is formed in a side edge portion of the bottom surface of the shift stopper, and wherein, when a manual shift mode signal is generated by the manipulation of the mode selection portion and an operation signal of the clutch pedal is generated, the shift lever controller controls the operation of the shift solenoid so that the stroke limiter exits from the stop groove and is spaced apart from the stop groove.

[0022] A stop groove is formed in a side edge portion of the bottom surface of the shift stopper, wherein, when a manual shift mode signal is generated by the manipulation of the mode selection portion and an operation signal of the clutch pedal is not generated, the shift lever controller controls the operation of the shift solenoid so that the stroke limiter is in a state of being inserted into the stop groove, and wherein, when the shift stopper is moved in the shift direction by the manipulation of the shift lever in the shift direction, a side wall of the stop groove comes into contact with a side surface of the stroke limiter so that the movement of the shift stopper in the shift direction is restricted, and the operation of the manual shift is no longer performed.

[0023] When the shift stopper pin is located in the inner groove in the case of the automatic shift mode, the position of the shift lever is fixed in an initial position or an M position, wherein, when the shift lever is moved toward any one of the shift positions of the D range, the (-) range, the R range, and the (+) range, the shift stopper pin is moved toward the protruding portion, and wherein, when the operation force is released in a state in which the shift lever is moved to any one of the shift positions of the D range, the (-) range, the R range, and the (+) range, the shift stopper pin returns to the inner groove by the spring force, and the shift lever returns to the initial position or the M range position.

[0024] When the shift stopper pin located in the inner groove is moved toward the protruding portion by the manipulation of the shift lever in the shift direction, the shift stopper is moved in the shift direction, and the shift spring is compressed, and wherein, when the shift stopper pin is located on the protruding portion, a side wall of the stop groove comes into contact with a side surface of the stroke limiter so that the shift stopper is restricted so that the shift stopper no longer moves in the shift direction.

[0084] Hereinafter, an electronic shift operation apparatus according to an exemplary embodiment of the present disclosure will be described with reference to the accompanying drawings.

[0085] 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 pleasure to the driver and improve marketability.

[0086] In addition, 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.

[0087] 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.

[0088] 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.

[0089] Further, the electronic shift operation apparatus according to the present disclosure can include a system implementing a mode switching device for shift operation and a stroke limiting device for limiting a shift direction stroke of a shift lever.

[0090] First, a mode switching device capable of switching a mode to an automatic shift mode or a manual shift mode based on an intention of a driver will be described.

[0091] The electronic shift operation apparatus according to the present 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 switching 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 switching guide 50 into which an end of the mode switching lever 40 is inserted, the mode switching guide 50 having a first selection groove 51 configured to guide movement of the mode switching lever 40 in the selection direction in the automatic shift mode and a second selection groove 52 configured to guide movement of the mode switching lever 40 in the selection direction in the manual shift mode.

[0092] 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.

[0093] The electronic shift operation apparatus according to the present 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] One end of the mode switching lever 40 can be inserted into one end of the hinge shaft 30. The mode switching lever 40 can be installed to be movable in a longitudinal direction of the hinge shaft 30.

[0098] The other end of the mode switching lever 40 is installed to be inserted into the first selection groove 51 or the second selection groove 52 formed in the mode switching guide 50. The first selection groove 51 and the second selection groove 52 are connected by the connection groove 53.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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 installed to be inserted into a first side groove 61 of the ball cover bracket 60.

[0104] 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.

[0105] 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.

[0106] 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 in the shift direction around the hinge shaft 30.

[0107] 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.

[0108] As the ball cover 20 rotates in the selection direction, when the end of the hinge shaft 30 comes into contact with the upper end or the lower end of the first side groove 61, the rotation in the selection direction can be restricted.

[0109] 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 the rotation of the mode switching lever 40 can be restrained and restricted by the hinge shaft 30.

[0110] 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.

[0111] Therefore, 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 the rotation of the mode switching lever 40 is restricted from being performed by the cross-sectional shape of the hinge shaft 30.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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 installed to be movable in the shift direction, and a mode switching solenoid 110 fixedly coupled to a 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.

[0116] The mode switching guide bracket 90 can be fixedly coupled to a side surface of the ball cover bracket 60 forming the first side groove 61.

[0117] The inside of the mode switching guide bracket 90 is empty, and the mode switching guide 50 is inserted and mounted into the mode switching guide bracket 90. 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 when the mode switching solenoid 110 is operated.

[0118] 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.

[0119] The mode switching solenoid 110 can be connected to the mode switching guide 50. 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 when the mode switching solenoid 110 can be operated.

[0120] 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.

[0121] The mode switching guide 50 can have first and second selection grooves 51 and 52 into which the end of the mode switching lever 40 is inserted, and a connection groove 53 connecting the first and second selection grooves 51 and 52.

[0122] Referring to Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 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.

[0123] Referring to Figure 15 , Figure 16 , Figure 17 , Figure 18 and Figure 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.

[0124] When the mode switching guide 50 moves in the shift direction by the operation of the mode switching solenoid 110, 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 in the second selection groove 52 by the movement of the mode switching guide 50 in the shift direction.

[0125] Referring to Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 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 knob 20 is rotated in the selection direction, the mode switching lever 40 can move between the null position A1 and the M position A2 and stop at the null position A1 or the M position A2.

[0126] That is, in the automatic shift mode, the null position A1 and the M position A2 can be fixed ends in which the mode switching lever 40 is fixed.

[0127] The locking protrusion 54 can protrude between the null 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 located at the null position A1 or the M position A2, the 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.

[0128] Referring to Figure 15 , Figure 16 , Figure 17 , Figure 18 and Figure 19 , in the manual shift mode, the second selection groove 52 in which the mode switching lever 40 is located can include a null position (N position, neutral position, 3 / 4 position selection position) B1 connected to the connection groove 53, a 5 / 6 position selection position B2 spaced apart from the null position B1 in one direction, and a 1 / 2 position selection position B3 and an R position selection position B4 spaced apart from the null position B1 in the other direction.

[0129] When the knob 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 position selection position B2 and the R position 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 null position B1 by the spring force.

[0130] That is, in the manual shift mode, the 5 / 6th gear selection position B2, the 1 / 2nd gear selection position B3, and the R range selection position B4 are fixed ends where the 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 is selected, the mode switching lever 40 returns to the initial position Bl by the spring force.

[0131] The locking protrusion 54 is provided in the first selection groove 51. Therefore, in the automatic shift mode, when the mode switching lever 40 is moved from the initial position Al 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.

[0132] 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 shift mode, when the shift lever 10 performs the selection manipulation, the mode switching lever 40 can be easily moved along the second selection groove 52 without any interference.

[0133] Therefore, with the locking protrusion 54, the selection operation force of the shift lever 10 in the automatic shift mode can be larger than that of the shift lever 10 in the manual shift mode, and thus is easily recognized by the driver.

[0134] 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 penetrating in the shift direction, and a selection roller 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 roller 140. The selection roller 140 can move along the selection stop grooves 160 when the ball cover 20 is rotated in the selection direction.

[0135] 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.

[0136] First side grooves 61 can be respectively formed on both opposite side surfaces of the ball cover bracket 60 directed to the selection direction. A mode switching guide bracket 90 and a 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.

[0137] 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 roller 140 is rotatably coupled to both opposite ends of the roller shaft 150.

[0138] The selection roller 140 can be installed to be in contact with a selection stop groove 160 formed in a selection stop bracket 170. When the ball cover 20 is rotated in the selection direction, the selection roller 140 can move along the selection stop groove 160.

[0139] Referring to Figure 25 , the selection stop groove 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.

[0140] 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.

[0141] 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.

[0142] Referring to Figure 11 and Figure 25 , in the automatic shift mode in which the mode switching lever 40 is located in the first selection groove 51, when the mode switching lever 40 is located in the initial position A1, the selection roller 140 can be located in the first groove 161, and when the mode switching lever 40 is located in the M position A2, the selection roller 140 can be located in the third groove 163.

[0143] Further, referring to Figure 16 and Figure 25 , in the manual shift mode in which the mode switching lever 40 is located in the second selection groove 52, when the mode switching lever 40 is located in the initial position B1, the selection roller 140 can be located in the first groove 161, when the mode switching lever 40 is located in the 1 / 2 shift selection position B3, the selection roller 140 can be located in the third groove 163, when the mode switching lever 40 is located in the R shift selection position B4, the selection roller 140 can be located in the fourth groove 164, and when the mode switching lever 40 is located in the 5 / 6 shift selection position B2, the selection roller 140 can be located in the second groove 162.

[0144] The electronic shift operation apparatus according to the present disclosure can further include a second spring fixing pin 180 coupled to penetrate a longitudinal direction-based midpoint of the hinge shaft 30, 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.

[0145] The second spring fixing pin 180 can be coupled to penetrate the longitudinal direction-based midpoint of the hinge shaft 30 in the shift direction. The first spring fixing pin 70 and the second spring fixing pin 180 can be spaced left and right from the longitudinal direction-based midpoint of the hinge shaft 30 and installed in parallel with the longitudinal direction-based midpoint of the hinge shaft 30.

[0146] 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.

[0147] 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 range in which the selection spring 190 is stretched along the hinge shaft 30, so that the degree of protrusion of the guide tube 130 from the hinge shaft 30 can be increased.

[0148] 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 the 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.

[0149] The pattern guide pin 200 can be connected to the central portion of the lower portion of the ball cover 20, and the pattern guide pin 200 can rotate integrally with the ball cover 20 as the ball cover 20 rotates in the selection direction and the shift direction.

[0150] The 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 as the ball cover 20 rotates in the selection direction and the shift direction.

[0151] Referring to Figure 27 and Figure 28The pattern guide rail 210 can include a selection rail 211 configured to guide movement of the pattern guide pin 200 in a selection direction, and a shift rail 212 configured to guide movement of the pattern guide pin 200 in a shift direction.

[0152] Figure 27 and Figure 28 The state 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 is shown.

[0153] Referring to Figure 11 In the automatic shift mode, the mode switching lever 40 is positioned 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.

[0154] Accordingly, 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.

[0155] On the contrary, referring to Figure 16 In the manual shift mode, the mode switching lever 40 is positioned in the second selection groove 52, and during the selection manipulation, the mode switching lever 40 can move along all selection paths from the initial position B1 which is a neutral (N) position to the 5 / 6 shift selection position B2 in one direction and the 1 / 2 shift selection position B3 and the R shift selection position B4 in the other direction.

[0156] Accordingly, in the manual shift mode, the pattern guide pin 200 can move in the selection direction along all selection routes without being limited.

[0157] The initial position A1 in the automatic shift mode can correspond to a Null position, the initial position B1 in the manual shift mode can correspond to an N position, a neutral, or a 3 / 4 shift selection position, and the initial position A1 in the automatic shift mode and the initial position B1 in the manual shift mode can be the same position.

[0158] Further, the M position A2 in the automatic shift mode can be the 1 / 2 shift selection position B3 in the manual shift mode.

[0159] According to the present disclosure, a shift direction stroke can be differently limited in the automatic shift mode and the manual shift mode. This can be performed by a shift direction stroke limiting device which will be described below.

[0160] The shift direction stroke is relatively shorter in the automatic shift mode than in the manual shift mode, which can improve operational convenience.

[0161] In contrast, the shift direction stroke in the manual shift mode is relatively longer than in the automatic shift mode, which can improve the recognition performance during the shift operation.

[0162] 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.

[0163] 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 recognizing a magnetic flux signal according to a change in position of the permanent magnet 230 when the ball cover 20 is rotated in the selection direction and the shift direction.

[0164] 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.

[0165] 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.

[0166] 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 a vehicle controller 250, and configured to control the operation of the mode switching solenoid 110 by receiving a signal of the mode selection portion 120, which can select the automatic shift mode and the manual shift mode.

[0167] 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 the signal, and the shifter controller 260 including the PCB 240 can be covered and protected by a controller cover 270.

[0168] The controller cover 270 can be fixedly coupled to a side surface of the ball cover bracket 60.

[0169] Reference Figure 42The automatic shift mode signal or the manual shift mode signal generated by manipulation of the mode selection portion 120 is transmitted to the shift lever controller 260, and the shift lever 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.

[0170] Further, the shift position signal selected by the selective 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 shift lever controller 260, and the operation of the vehicle driving portion 280 can be controlled by the vehicle controller 250.

[0171] The 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 switching lever 40 configured to be connected to a shift lever 10, and a mode switching guide 50 having a first selection groove 51 and a second selection groove 52 configured to guide movement of the mode switching 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 switching guide 50 is moved in a shift direction by the operation of the mode switching solenoid 110. When the mode switching guide 50 is moved in the shift direction, the mode switching guide 50 is moved in a state in which the mode switching lever 40 is inserted into the connection groove 53, so that the mode switching lever 40 can be located in the first selection groove 51 or in the second selection groove 52.

[0172] In the automatic shift mode, the mode switching lever 40 can be located in the first selection groove 51 and moved along the first selection groove 51 to an initial position A1 or an M position A2 by manipulation of the shift lever 10 in the selection direction.

[0173] In the automatic shift mode, the initial position A1 can be a Null position.

[0174] Further, in the manual shift mode, the mode switching 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 B1, a 5 / 6 shift selection position B2, a 1 / 2 shift selection position B3, and an R shift selection position B4 by manipulation of the shift lever 10 in the selection direction.

[0175] In the manual shift mode, the initial position B1 can be an N position, a Neutral position, and a 3 / 4 shift selection position.

[0176] 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.

[0177] 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 differently limited.

[0178] That is, in the automatic shift mode, the shift direction stroke can be limited to a relatively shorter length than in the manual shift mode, which can improve operation convenience.

[0179] 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 recognition performance during a shift operation.

[0180] 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 those during a shift operation of an automatic transmission vehicle and a manual transmission vehicle in the related art, which can eliminate heterogeneity of the vehicles in the related art.

[0181] To implement this configuration, the electronic shift operation apparatus according to the present disclosure can include a ball cover 20 coupled to the shift lever 10 and configured to rotate in the selection direction and the shift direction when the shift lever 10 is manipulated by the driver, 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.

[0182] The shift stop pin 290 can be fixedly coupled to a position of the ball cover 20 directed to the shift direction.

[0183] 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.

[0184] 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.

[0185] 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.

[0186] The shift stop 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 stop 320, and the end of the shift stop pin 290 can have a structure that is always in contact with the shift stop groove 310.

[0187] When the ball cover 20 is rotated 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.

[0188] 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.

[0189] 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 the boss portion 291 of the shift stop pin 290 can be inserted and installed into the second side groove 62. When the shift lever 10 is manipulated in the shift direction, the boss portion 291 of the shift stop pin 290 is in contact with one end or the other end of the second side groove 62, and the full stroke in the shift direction can be limited.

[0190] When the ball cover 20 is rotated in the shift direction by manipulation of the shift lever 10, the ball cover 20, the shift stop 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.

[0191] When the boss portion 291 of the shift stop pin 290 is in contact with 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.

[0192] The electronic shift operation apparatus according to the present disclosure can further include a shift stopper bracket 330 fixedly coupled to a shift direction-based side of the ball cover bracket 60, 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 being configured to differently limit a shift direction movement stroke of the shift stopper 320 based on a position of the movement.

[0193] The shift stopper bracket 330 can be fixedly coupled to a side surface of the ball cover bracket 60 forming the second side groove 62. The shift stopper 320 can be inserted into the shift stopper bracket 330 and mounted and configured to be movable in the shift direction.

[0194] When the ball cover 20 is rotated in the shift direction as the driver manipulates the shift lever 10, the shift stopper pin 290 can move along the shift stopper groove 310 in a state in which the shift stopper pin 290 is in contact with the shift stopper groove 310. When the shift stopper pin 290 moves, the shift stopper 320 can move in the shift direction in a state in which the shift stopper 320 is inserted into the shift stopper bracket 330 by a phase difference of the shift stopper groove 310.

[0195] 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 stopper 320 and the shift stopper bracket 330, and the shift spring 340 can provide a spring force moving the shift stopper 320 toward the ball cover 20.

[0196] The shift solenoid 350 can be fixedly coupled to the shift stopper 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.

[0197] The solenoid cover 370 can be coupled to the shift stopper bracket 330, and the shift solenoid 350 and the stroke limiter 360 can be covered and protected by the solenoid cover 370.

[0198] 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 a signal of the clutch pedal 380. The stroke limiter 360 can be moved upward or downward by the operation of the shift solenoid 350.

[0199] When the automatic shift mode signal is generated, the stroke limiter 360 can be fixed in a state in which the stroke limiter 360 is moved to an upper side in which the shift stopper 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 is moved to a lower side away from the shift stopper 320. When the manual shift mode signal is generated without the operation signal of the clutch pedal 380 being generated, the stroke limiter 360 can be fixed in a state in which the stroke limiter 360 is moved to the upper side.

[0200] 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.

[0201] 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 and the operation signal of the clutch pedal 380.

[0202] 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 dual 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 is moved 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 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 is moved to a lower side away from the shift stopper 320.

[0203] A plurality of guide protrusions 321 and a plurality of guide grooves 331 for guiding the shift stopper 320 to move in a 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.

[0204] A plurality of guide protrusions 321 can be formed on the outer circumferential surface of the shift stopper 320 and spaced apart from each other. A number of guide grooves 331 equal to the number of the guide protrusions 321 can be formed on the inner circumferential surface of the shift stopper bracket 330 and provided at portions matching the guide protrusions 321.

[0205] The guide protrusions 321 and the guide grooves 331 can extend in a shift direction in which the shift stopper 320 moves.

[0206] Referring to Figure 34 to Figure 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 a 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.

[0207] Referring to Figure 35 to Figure 37 , a stop groove 322 is formed in a side edge portion of a bottom surface of the shift stopper 320, and one side of an upper end of the stroke limiter 360 is inserted into the stop groove 322 in the automatic shift mode. In the automatic shift mode, when the shift stopper 320 is moved in a 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 a point in time when a side wall of the stop groove 322 comes into contact with one side surface of the stroke limiter 360.

[0208] When the automatic shift mode signal is generated by 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 is in a state of being inserted into the stop groove 322.

[0209] Figure 35 A state in which the shift stopper pin 290 is located in the inner groove 311 in the automatic shift mode is shown, Figure 36 to Figure 37 a state in which the shift lever 10 is rotated in the shift direction from Figure 35 a state in which the shift lever 10 is rotated in the shift direction from

[0210] As shown in Figure 35 , when the shift stopper pin 290 is located in the inner groove 311 in the automatic shift mode, the position of the shift lever 10 can be fixed at a null position Al or an M (manual) position A2.

[0211] Figure 36 and Figure 37 a state in which the shift lever 10 is rotated in the shift direction from Figure 35the state in which the state in the shift lever 10 is rotated clockwise and counterclockwise in the shift direction.

[0212] When the ball cover 20 is rotated by the rotation of the shift lever 10 in the shift direction, the shift stop pin 290 moves from the inner groove 311 toward the outer groove 312 in a state in which the shift stop pin 290 is in contact with the shift stop groove 310, and the shift stop 320 is moved to the left by the movement of the shift stop pin 290. In this case, the shift spring 340 is compressed.

[0213] The movement of the shift stop 320 in the shift direction is limited at a time when the side wall of the stop groove 322 comes into contact with one side surface of the stroke limiter 360 as the shift stop 320 is moved to the left. In this case, the shift stop pin 290 is positioned on the protrusion part 313 of the shift stop groove 310.

[0214] When the shift stop pin 290 is positioned on the protrusion part 313, the shift lever 10 can be moved toward any one of the shift positions of the D range, the (-) range (down range), the R range, and the (+) range (up range).

[0215] That is, when the shift lever 10 is moved toward any one of the shift positions of the D range, the (-) range, the R range, and the (+) range, the shift stop pin 290 can be moved toward the protrusion part 313.

[0216] Further, when the operating force is released in a state in which the shift lever 10 is moved to any one of the shift positions of the D range, the (-) range, the R range, and the (+) 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.

[0217] Referring to Figure 38 to 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 stop 320 is moved in the shift direction by the manipulation of the shift lever 10 in the shift direction, the shift stop 320 can be moved without being in contact with the stroke limiter 360.

[0218] That is, when the stroke limiter 360 is lowered and deviates from the movement path of the shift stop 320 based on the shift direction, the shift stop 320 is not in contact with the stroke limiter 360 as the shift stop 320 is moved in the shift direction. Accordingly, the shift stop 320 can be moved by the maximum distance in the shift direction.

[0219] When a manual shift mode signal is generated by manipulation of the mode selection portion 120 and an operation signal of the clutch pedal 380 is generated, the shift lever controller 260 can control the operation of the shift solenoid 350 so that the stroke limiter 360 is withdrawn from the stop groove 322 and is spaced apart from the stop groove 322.

[0220] Figure 38 A state in which the shift stopper 290 is located in the inner groove 311 in the case of the manual shift mode is shown, Figure 39 to Figure 40 A state in which the shift lever 10 is rotated in the shift direction from Figure 38 A state in which the shift lever 10 is rotated in the shift direction from

[0221] As shown in Figure 38 When the shift stopper 290 is located in the inner groove 311 in the case of the manual shift mode, the shift lever 10 can be located in any one of an initial position (N range, neutral, and 3 / 4 range selection position) B1, a 5 / 6 range selection position B2, a 1 / 2 range selection position B3, and an R range selection position B4.

[0222] When the operation force of the shift lever 10 is released in a state in which the shift stopper 290 is located 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 be returned to the initial position B1 by the spring force.

[0223] Figure 39 A state in which the shift lever 10 is rotated in the shift direction from Figure 40 A state in which the shift lever 10 is rotated in the shift direction from Figure 38 A state in which the shift lever 10 is rotated in the shift direction from

[0224] When the ball cover 20 is rotated by the rotation of the shift lever 10 in the shift direction, the shift stopper 290 moves 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.

[0225] As the shift stopper 320 is moved to the left, the shift stopper 290 passes over the protrusion 313, and the shift stopper 290 is inserted into the outer groove 312 and then fixed at an appropriate position in the outer groove 312.

[0226] When the shift stopper 290 is located in the outer groove 312, the shift lever 10 can be positioned to be fixed at any one of a 1st range, a 2nd range, a 3rd range, a 4th range, a 5th range, a 6th range, and an R range.

[0227] Figure 41A case where a manual shift mode signal is generated by manipulation of the mode selection portion 120, but an operation signal of the clutch pedal 380 is not generated since the driver does not manipulate the clutch pedal 380.

[0228] 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.

[0229] Therefore, when the shift stopper 320 is moved in the shift direction by manipulation of the shift lever 10 in the shift direction, the side wall of the stop groove 322 comes into contact with the side surface of the stroke limiter 360 so that the movement of the shift stopper 320 in the shift direction is limited, and the operation of manual shifting is no longer performed.

[0230] That is, when the driver manipulates the shift lever 10 in the shift direction in a state where the manual shift mode signal is generated and the operation signal of the clutch pedal 380 is not generated, the shift stopper 320 is allowed to move in the shift direction until the side wall of the stop groove 322 comes into contact with the side surface of the stroke limiter 360. When the side wall of the stop groove 322 comes into contact with the side surface of the stroke limiter 360, the movement of the shift stopper 320 in the shift direction is limited by the stroke limiter 360.

[0231] As described above, in the state where the movement of the shift stopper 320 in the shift direction is limited by the stroke limiter 360, the shift stopper pin 290 is located on the protruding portion 313, and the movement of the shift stopper pin 290 toward the outer groove 312 that outputs the shift position signal is limited. Therefore, the shift position signal is not output, which can prevent erroneous operation.

[0232] Further, when the operation force of the shift lever 10 is released in the state where the shift stopper pin 290 is located on the protruding portion 313, the shift stopper pin 290 is returned to the inner groove 311 by the spring force, and the shift lever 10 is returned to the initial position B1.

[0233] Hereinafter, a system of a shift operation device according to the present disclosure will be described.

[0234] An electronic shift operation apparatus according to the present disclosure can include a shift lever 10 operable in a selection direction along a selection rail 211 and in a shift direction along a plurality of shift rails 212 connected to the selection rail 211, and a mode selection portion 120 capable of selecting an automatic shift mode or a manual shift mode. The mode can be switched to the automatic shift mode enabling automatic shift manipulation or the manual shift mode enabling manual shift manipulation according to an input of the mode selection portion 120. When the shift lever 10 is manipulated in the selection direction along the selection rail 211, a movement route of the shift lever 10 can vary according to the automatic shift mode and the manual shift mode. When the shift lever 10 is manipulated in the shift direction along the shift rail 212, a shift direction stroke of the shift lever 10 can vary according to the automatic shift mode and the manual shift mode.

[0235] Further, the electronic shift operation apparatus according to the present disclosure can further include a mode switching solenoid 110 configured to operate to switch the mode to the automatic shift mode or the manual shift mode, and a shifter controller 260 configured to control the operation of the mode switching solenoid 110 by receiving a signal of the mode selection portion 120.

[0236] The shifter controller 260 can control the operation of the mode switching solenoid 110 so that, in the automatic shift mode, movement of the shift lever 10 in the selection direction is limited to a selection position located at an edge of the selection rail 211.

[0237] Referring to Figure 11 In the automatic shift mode, when the shift lever 10 is manipulated in the selection direction, selection movement of the shift lever 10 can be limited to the 5 / 6th gear selection position and the R range selection position in the manual shift mode.

[0238] The shifter controller 260 can control the operation of the mode switching solenoid 110 so that, in the automatic shift mode, a selection manipulation force when the shift lever 10 is manipulated in the selection direction is higher than a selection manipulation force when the shift lever 10 is manipulated in the selection direction in the manual shift mode.

[0239] That is, in the automatic shift mode, when the shift lever 10 performs selection manipulation from the initial position Al to the M position A2, an operation force is generated as the mode switching lever 40 climbs over the locking protrusion 54, and the selection manipulation force in the automatic shift mode is higher than the selection manipulation force in the manual shift mode by the locking protrusion 54. Accordingly, recognition performance of the driver can be improved.

[0240] Referring to Figure 12 and Figure 14In the automatic shift mode, when the mode switch lever 40 is located in the M position A2 by the selection manipulation of the shift lever 10, the position of the mode switch lever 40 is fixed in the M position A2 by the locking protrusion 54, and the movement of the shift lever 10 can be stopped.

[0241] 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 shifter controller 260 and to operate differently to limit the shift direction stroke of the shift lever 10 according to the automatic shift mode and the manual shift mode.

[0242] The shifter 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.

[0243] 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.

[0244] 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 in the initial position A1 or the M position A2 is manipulated in the shift direction, and then the operating force is eliminated so that the shift lever 10 can return to the initial position A1 or the M position A2 by the spring force.

[0245] In the automatic shift mode, the initial position A1 can be a Null position.

[0246] Further, in the manual shift mode, the shift lever 10 performs a selection operation to the 5 / 6 shift selection position B2, the 1 / 2 shift selection position B3, or the R shift selection position B4, and then the operating force is eliminated so that the shift lever 10 can return to the initial position B1.

[0247] In the manual shift mode, the initial position B1 can be the N shift, the Neutral position, and the 3 / 4 shift selection position.

[0248] In the manual shift mode, the end of the shift rail 212 is defined as a fixed end, the shift lever 10 is manipulated in the shift direction, and then the operating force is eliminated so that the shift lever 10 can be fixed in any one of the 1st shift, the 2nd shift, the 3rd shift, the 4th shift, the 5th shift, the 6th shift, and the R shift.

[0249] According to the present disclosure, the shift lever 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 shift lever 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 (D range, R range, (+) range, or (-) range) regardless of the operation signal of the clutch pedal 380.

[0250] Further, the shift lever 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 (1st range, 2nd range, 3rd range, 4th range, 5th range, 6th range, or R range) only in a state where both a manual shift mode signal input by manipulation of the mode selection portion 120 and the operation signal of the clutch pedal 380 are input.

[0251] Further, when a manual shift mode signal is input to the shift lever controller 260 by manipulation of the mode selection portion 120 and the operation signal of the clutch pedal 380 is not input, the shift lever 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 (1st range, 2nd range, 3rd range, 4th range, 5th range, 6th range, or R range).

[0252] When an automatic shift mode signal is generated by manipulation of the mode selection portion 120 in a vehicle not equipped with a clutch pedal (e.g., a dual pedal vehicle), the shift lever controller 260 can control the stroke limiter 360 so that the stroke limiter 360 is fixed in a state where the stroke limiter 360 moves to an upper side where the shift stopper 320 is present. When a manual shift mode signal is generated by 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 where the stroke limiter 360 moves to a lower side away from the shift stopper 320.

[0253] 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 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 restrict the shift lever 10 from moving to any one or more of the plurality of selection positions positioned along the selection rail 211.

[0254] 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 restricted 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.

[0255] In the manual shift mode, the plurality of selection positions can include: an initial position B1 to which the shift lever 10 is returned by a spring force when an operation force in the selection direction of the shift lever 10 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 or 6th gear can be selected by 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 or 2nd gear can be selected by 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 manipulation of the shift lever 10 in the shift direction. The initial position B1 can be a 3 / 4 shift selection position B1 at which the 3rd or 4th gear can be selected by manipulation of the shift lever 10 in the shift direction.

[0256] In the automatic shift mode, one of 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 the R gear or the D gear 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 the (+) gear (upshift) or the (−) gear (downshift) can be selected by manipulation of the shift lever 10 in the shift direction.

[0257] 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 shift selection position B3 in the manual shift mode.

[0258] 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 operation force is removed at the M position A2.

[0259] 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.

[0260] Further, the shifter controller 260 can receive RPM information of the vehicle through signals of the accelerator pedal 390 and the brake pedal 400.

[0261] As described above, the electronic shift operation apparatus according to the present disclosure can switch the mode of the shift operation to automatic shifting or manual shifting based on the intention of the driver. Thus, the simplicity of the shift operation can be eliminated, which can provide the driver with fun and improve marketability.

[0262] 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 the manipulation and improving the recognition performance during the shift operation.

[0263] 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.
