Description

BACKGROUND OF REVELATION Area of ​​Revelation

[0001] The present disclosure relates to an electronic switching device and, in particular, to a technology relating to an electronic switching device that is capable of switching a switching mode to manual and automatic shifting depending on the driver's intention and of limiting the switching direction strokes of a shift rod differently in accordance with an automatic and a manual shifting mode. Description of the state of the art

[0002] In general, a vehicle with an automatic transmission enables the automatic actuation of gears within a target shift position range by controlling the hydraulic pressure within a shift range that is determined depending on the vehicle's driving speed.

[0003] The automatic transmission generates a gear ratio using a hydraulic circuit, a planetary gear set and friction elements to perform a shifting operation, and a transmission control unit (TCU) controls the individual components.

[0004] A shift-by-wire (SBW) system, which is an electronic transmission system for a vehicle, refers to an electronic transmission system that, unlike a mechanical transmission system in the related technology, has no mechanical connection structure, such as a cable, between a gearbox and a shift lever. When a sensor value, generated when a transmission mechanism (a shift lever, a shift knob, or a selector dial) is actuated, is transmitted to the transmission control unit (TCU), the TCU performs electronic shift control in response to a given signal.

[0005] Therefore, the automatic transmission, which operates using the SBW (Self-Bordered Unit), transmits the driver's shift intention to the TCU (Transmission Control Unit) in the form of an electrical signal. The TCU then simply actuates the electronic transmission mechanism in such a way that the shift into D (Drive), R (Reverse), N (Neutral), and so on, can be carried out smoothly. Furthermore, the transmission mechanism can be miniaturized, which allows for a larger space between the driver's and passenger's seats.

[0006] The foregoing background information is intended only to facilitate understanding of the background of the present disclosure and is not intended to imply that the present disclosure falls within the scope of related prior art already known to the skilled person. OVERVIEW OF THE REVELATION

[0007] The present disclosure is intended to solve these problems and aims to provide an electronic switching device capable of differently limiting switching direction strokes of a shift rod in accordance with an automatic switching mode and a manual switching mode, thereby improving performance in detecting a switching operation in automatic or manual switching mode and enhancing marketability.

[0008] To achieve the above-mentioned objective, the present disclosure provides an electronic switching device comprising: a mode selection part configured to select an automatic switching mode or a manual switching mode; and a shift rod configured to be operated by a driver in a selection direction and a switching direction, wherein the switching direction strokes of the shift rod are limited differently in the automatic switching mode and in the manual switching mode.

[0009] The stroke of the shift rod in the shifting direction can be limited so that it is relatively shorter in automatic shifting mode than in manual shifting mode, and relatively longer in manual shifting mode than in automatic shifting mode.

[0010] The electronic shift actuation device may comprise: a ball cover coupled to the shift rod and configured to rotate in the selection direction and the shift direction when the driver operates the shift rod; a shift detent pin coupled to the ball cover and configured to rotate together with the ball cover when the shift rod is operated in the shift direction; and a shift detent with a shift cam configured to be in contact with the shift detent pin, the shift detent pin moving along the shift cam when the shift rod is operated in the shift direction.

[0011] The stroke with which the shift detent pin moves along the shift gate can be relatively shorter in automatic shifting mode than in manual shifting mode, and relatively longer in manual shifting mode than in automatic shifting mode.

[0012] The electronic switching device may further include: a ball cover holder configured to cover the ball cover and to guide rotations of the ball cover in the selection direction and the switching direction.

[0013] A second side groove is formed in a surface of the ball cover holder according to the shifting direction, into which a hub section of the shift detent pin is inserted and installed in the second side groove, and in which a full stroke in the shifting direction is limited when the hub section of the shift detent pin comes into contact with one end or the other of the second side groove when the shift rod is actuated in the shifting direction.

[0014] The electronic switching actuator may further comprise: a detent carrier rigidly coupled to one side of the ball cover carrier with respect to the switching direction, wherein the detent is inserted into the detent carrier and installed so that it is movable in the switching direction; a switching spring with two opposite ends connected to the detent carrier and the detent and configured to provide an elastic force for the movement of the detent; a switching solenoid coil rigidly coupled to the detent carrier and configured to operate by receiving an automatic switching mode signal or a manual switching mode signal;and a stroke limiter coupled to the switching solenoid coil and configured to move away from or towards the switching detent when the switching solenoid coil is operating, wherein the stroke limiter is configured to limit the strokes of movement of the switching detent differently based on a moving position.

[0015] The electronic switching device may further include: a switching control attached to the ball cover bracket and configured to control the operation of the switching magnet by receiving a signal from a mode selection part and a signal from a clutch pedal.

[0016] Several guide projections and several guide grooves can be formed on the switching detent and the switching detent carrier and guide the movement of the switching detent in the switching direction in such a way that the guide projections and the guide grooves are coupled to each other.

[0017] The switching mechanism may comprise: an inner groove formed as a concave groove in a central section of a surface of the switching detent; an outer groove formed as a concave groove outside the inner groove and connected to the inner groove in a circumferential direction; and a projecting section formed between the inner groove and the outer groove to connect the inner groove and the outer groove, the projecting section having a cross-section that projects from the inner groove and the outer groove and is connected to the inner groove and the outer groove in the circumferential direction.

[0018] A detent groove is formed in a side edge section of a bottom surface of the detent, wherein a side of an upper end of the stroke limiter is inserted into the detent groove in an automatic switching mode situation, and wherein, in the automatic switching mode situation, when the detent is moved in the switching direction by actuation of the switching rod in the switching direction, the movement of the detent in the switching direction is limited at a time when a side wall of the detent groove comes into contact with a side surface of the stroke limiter.

[0019] If the signal for the automatic switching mode is generated by actuating the mode selection part, the switching control controls the operation of the switching solenoid coil so that the stroke limiter is inserted into the detent groove.

[0020] In a side edge section of a bottom surface of the switching detent, a detent groove is formed in which, in a manual switching mode situation, when the stroke limiter is lowered by actuation of the switching solenoid coil, the stroke limiter is retracted and spaced away from the detent groove, and in which, in the manual switching mode situation, when the switching detent is moved in the switching direction by actuation of the switching rod, the switching detent moves without coming into contact with the stroke limiter.

[0021] A detent groove is formed in a side edge section of a base surface of the shift detent, in which, when both the manual shift mode signal is generated by actuating the mode selection part and the actuating signal of the clutch pedal, the shift control controls the operation of the shift magnet in such a way that the stroke limiter is retracted and spaced away from the detent groove.

[0022] A detent groove is formed in a side edge section of a base surface of the shift detent, wherein the signal for the manual shift mode is generated by actuating the mode selection part and the actuation signal of the clutch pedal is not generated, wherein the shift control controls the operation of the shift magnet such that the stroke limiter is in a state in which it is inserted into the detent groove, and in which, when the shift detent is moved in the shift direction by actuating the shift rod, a side wall of the detent groove comes into contact with a side surface of the stroke limiter in such a way that the movement of the shift detent in the shift direction is restricted and the manual shifting process is not carried out further.

[0023] If the detent pin is positioned in the inner groove in automatic shift mode, a position of the shift rod is set in an initial position or an M position, in which, when the shift rod moves to any shift position between a D stage, a (-) stage, an R stage and a (+) stage, the detent pin moves towards the projecting section, and in which, when an actuating force is released in a state in which the shift rod is moved to any shift position between the D stage, the (-) stage, the R stage and the (+) stage, the detent pin is returned to the inner groove by a spring force and the shift rod is returned to the initial position or the M position.

[0024] If the detent pin positioned in the inner groove is moved towards the projection section by actuating the shift rod in the shifting direction, the detent moves in the shifting direction, and the shift spring is compressed, whereby, when the detent pin is positioned on the projection section, the side wall of the detent groove comes into contact with a side surface of the stroke limiter in such a way that the detent is restricted so that the detent does not move further in the shifting direction.

[0025] If the shift detent pin is positioned in the inner groove in the manual shift mode situation, the shift rod is positioned in any of the following: a home position, a 5 / 6-stage selection position, a 1 / 2-stage selection position, and an R-stage selection position. In these positions, when the shift rod is actuated in the shift direction in a state where the clutch pedal actuation signal is generated and the stroke limiter is retracted from the detent groove, the shift detent pin passes over the projection section and the position of the shift detent pin in the outer groove is fixed. In these positions, when the shift detent pin is positioned in the outer groove, the shift rod is positioned in a first stage, a second stage, a third stage, a fourth stage, a fifth stage, a sixth stage, or an R-stage.

[0026] If the shift detent pin is positioned in the inner groove in the manual shift mode situation, the shift rod is positioned in any of the following: a home position, a 5 / 6-stage selector position, a 1 / 2-stage selector position, and an R-stage selector position. When the shift rod is actuated in the shift direction in the state where the clutch pedal actuation signal is not generated, movement of the shift detent in the shift direction is permitted until a side wall of the detent groove comes into contact with a side face of the stroke limiter. When the side wall of the detent groove comes into contact with a side face of the stroke limiter, the movement of the shift detent in the shift direction is limited by the stroke limiter. In a state where the movement of the shift detent in the shift direction is limited by the stroke limiter, movement of the shift detent pin towards the outer groove is prevented.which is positioned on the protrusion section and outputs the switching position signal, is limited.

[0027] If an actuating force on the shift rod is released in the state where the shift detent pin is positioned on the projecting section, the shift detent pin is returned to the inner groove by a spring force, and the shift rod is returned to its starting position.

[0028] The electronic shifting device according to the present disclosure can switch the shifting mode to automatic or manual shifting based on the driver's intention. Therefore, it is possible to eliminate the complexity of the shifting process, which can enhance driver satisfaction and improve marketability.

[0029] Furthermore, according to the present disclosure, the electronic switching device can limit the switching direction strokes of the switching rod to different lengths in accordance with the automatic switching mode and the manual switching mode, thereby improving the ease of handling and the detection performance during the switching process.

[0041] An electronic switching device according to an exemplary embodiment of the present disclosure is described below with reference to the accompanying drawing figures.

[0042] The electronic switching device according to the present disclosure comprises a mode switching device capable of switching the mode of a shifting operation to an automatic or a manual shifting operation based on the driver's intention. Therefore, it is possible to eliminate the complexity of the shifting operation, which can enhance driver satisfaction and improve marketability.

[0043] Furthermore, the electronic switching device according to the present disclosure may include a stroke limiting device which is capable of limiting the switching direction strokes of a switching rod differently in accordance with an automatic switching mode and a manual switching mode.

[0044] Typically, the shift rod travel in automatic shift mode is relatively shorter than in manual shift mode, which can improve ease of use.

[0045] In contrast, the shift rod travel is relatively longer in manual shift mode than in automatic shift mode, which can improve detection performance during the shifting process.

[0046] Furthermore, the electronic switching device according to the present disclosure can include a system that implements the mode switching device for the switching operation and the stroke limiting device for limiting the switching direction stroke of the switching rod.

[0047] First, the mode switching device is described, which is able to switch the mode to automatic shifting mode or manual shifting mode based on the driver's intention.

[0048] The electronic switching device according to the present disclosure may comprise: a ball cover 20 coupled to a shift rod 10 and configured to rotate in a selection direction and a switching direction when a driver actuates the shift rod 10; a drive 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 the pivot point of the ball cover 20 when the ball cover 20 rotates in the switching direction; a mode switching rod 40 coupled to one end of the drive shaft 30 and configured to be movable in a longitudinal direction of the drive shaft 30; and a mode switching guide 50 into which one end of the mode switching rod 40 is inserted, the mode switching guide 50 having a first selection groove 51 configured toto guide the movement of the mode selector rod 40 in the selection direction in automatic switching mode, and to have a second selection groove 52 which is designed to guide the movement of the mode selector rod 40 in the selection direction in manual switching mode.

[0049] The shift rod 10 can have a button 11 which the driver can grasp by hand to operate the shift rod 10.

[0050] The electronic switching device according to the present disclosure can be mounted in a position where the driver can easily operate the shift rod 10. For example, the electronic switching device can be installed on a console, center console or the like in a vehicle, or, taking into account an autonomous driving situation, the electronic switching device can be installed on a seat.

[0051] The spherical cover 20 can be designed in the form of a spherical body with an empty interior or as an arrangement of hemispherical upper and lower covers.

[0052] The drive shaft 30 can be designed as a hollow shaft with an empty interior and penetrate the ball shell 20 in the selection direction.

[0053] The ball cover 20 and the drive shaft 30 can rotate together when the ball cover 20 rotates in the selection direction by being actuated by the shift rod 10. When the ball cover 20 rotates in the switching direction, only the ball cover 20 rotates, and the drive shaft 30 serves as the pivot point for the ball cover 20 without rotating itself.

[0054] One end of the mode selector rod 40 can be inserted into one end of the drive shaft 30. The mode selector rod 40 can be installed so that it can move along the length of the drive shaft 30.

[0055] The other end of the mode selector rod 40 is inserted into the first selection groove 51 or the second selection groove 52 in the mode selector guide 50. The first selection groove 51 and the second selection groove 52 are connected by a connecting groove 53.

[0056] If the mode switching guide 50 moves in the switching direction, the mode switching guide 50 can move in the state in which the other end of the mode switching rod 40 is inserted into the connecting groove 53, and the other end of the mode switching rod 40 can be positioned in the first selection groove 51 or in the second selection groove 52 by the movement of the mode switching guide 50 in the switching direction.

[0057] The electronic switching device according to the present disclosure may further comprise a ball cover holder 60 which is configured to cover the ball cover 20 and to guide the rotations of the ball cover 20 in the selection direction and the switching direction.

[0058] The ball cover bracket 60 can be hexahedral (six-sided) and configured as a unit consisting of upper and lower brackets.

[0059] The ball cover 20 can be positioned in the ball cover holder 60. An inner surface of the ball cover holder 60 can be designed as a spherical surface, which facilitates the rotation of the ball cover 20 in the selection and switching direction.

[0060] The drive shaft 30 can penetrate the ball cover 20 in the selection direction. Two opposite ends of the drive shaft 30, projecting towards the outside of the ball cover 20, can be positioned so that they are inserted into the first lateral grooves 61 of the ball cover holder 60.

[0061] The first lateral grooves 61 can be designed to extend upwards and downwards into two surfaces positioned in the ball cover holder 60, depending on the selection direction.

[0062] The two opposite ends of the cardan shaft 30 and the first lateral grooves 61 have sections that face each other in the switching direction and are arranged to be in surface contact with each other.

[0063] Therefore, when the ball cover 20 is rotated in the switching direction by actuating the shift rod 10, the two opposite ends of the cardan shaft 30 are held back by the first side grooves 61 in such a way that the rotation of the cardan shaft 30 in the switching direction can be restricted and the ball cover 20 can rotate around the cardan shaft 30 in the switching direction.

[0064] If the ball cover 20 is rotated in the selection direction by actuating the shift rod 10, the ball cover 20 and the drive shaft 30 rotate together in the selection direction, and the first lateral grooves 61 can extend upwards and downwards from a side surface of the ball cover holder 60 in the illustrated state to guide the rotation of the drive shaft 30 in the selection direction.

[0065] Rotation in the selection direction can be inhibited if one end of the drive shaft 30 comes into contact with an upper or lower end of the first side groove 61 while the ball cover 20 is rotating in the selection direction.

[0066] The driveshaft 30 can be designed as a hollow shaft with an empty interior. One end of the mode selector rod 40 can be inserted into the driveshaft 30 in such a way that the mode selector rod 40 can move longitudinally along the driveshaft 30, and the rotation of the mode selector rod 40 can be inhibited and restricted by the driveshaft 30.

[0067] One end of the drive shaft 30 and one end of the mode switching rod 40 can be square in cross-section and correspond to each other.

[0068] Therefore, in the state where one end of the mode switching rod 40 is inserted into one end of the drive shaft 30, the mode switching rod 40 can only move in the longitudinal direction of the drive shaft 30, and the rotation of the mode switching rod 40 is restricted by the cross-sectional shape of the drive shaft 30 and cannot be carried out.

[0069] The electronic switching device according to the present disclosure can further comprise a first spring retaining pin 70 coupled in such a way that it penetrates a center point of the cardan shaft 30 in a longitudinal direction, and a mode switching spring 80 having two opposite ends which are connected and arranged to one end of the first spring retaining pin 70 and one end of the mode switching rod 40, exerting an elastic force on the mode switching rod 40.

[0070] The first spring fastening pin 70 is coupled in such a way that it penetrates into the center of the drive shaft 30 in the longitudinal direction in the switching direction.

[0071] The mode switching spring 80 can be designed as a coil spring and provide a spring force that pulls the mode switching rod 40 towards the inside of the drive shaft 30.

[0072] The electronic switching device according to the present disclosure can further comprise a mode-switching guide bracket 90 which is fixedly connected to one side of the ball cover holder 60, wherein the mode switching guide 50 is inserted into the mode-switching guide bracket 90 and is installed so that it is movable in the switching direction, and a mode-switching solenoid coil 110 (a mode switching solenoid) which is fixedly connected to a plate 100 which is coupled to the mode-switching guide bracket 90, wherein the mode-switching solenoid coil 110 is connected to the mode switching guide 50, is configured to move the mode switching guide 50 in the switching direction during actuation, and is configured to operate by receiving an automatic switching mode signal or a manual switching mode signal.

[0073] The mode-switching guide bracket 90 can be firmly connected to a side surface of the ball cover holder 60 in which the first side groove 61 is formed.

[0074] The mode switching guide bracket 90 has an empty interior, and the mode switching guide 50 is inserted and installed in the mode switching guide bracket 90. When a mode switching solenoid coil 110 is operating, the mode switching guide 50, in the state in which it is inserted into the mode switching guide bracket 90, can move in the switching direction.

[0075] The plate 100 is firmly connected to the mode-switching guide bracket 90, and the mode-switching solenoid coil 110 is firmly connected to the plate 100.

[0076] The mode-switching solenoid coil 110 can be connected to the mode switching guide 50. When the mode-switching solenoid coil 110 is operating, the mode switching guide 50 can move in the switching direction when inserted into the mode switching guide bracket 90.

[0077] If the driver activates a mode selection part 120, the automatic shift mode signal or the manual shift mode signal can be generated. The mode switching solenoid 110 can be activated by receiving the automatic shift mode signal or the manual shift mode signal.

[0078] The mode switching guide 50 can have the first selection groove 51 and the second selection groove 52, into which the end of the mode switching rod 40 is inserted, as well as the connecting groove 53, which connects the first selection groove 51 and the second selection groove 52.

[0079] With reference to Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13 and Fig. 14 In automatic switching mode, the end of the mode selector rod 40 is inserted into the first selection groove 51. In this state, the end of the mode selector rod 40 moves along the first selection groove 51 when the ball cover 20 rotates in the selection direction.

[0080] With reference to Fig. 15, Fig. 16, Fig. 17, Fig. 18 and Fig. 19 In manual switching mode, the end of the mode selector rod 40 is inserted into the second selection groove 52. In this state, the end of the mode selector rod 40 moves along the second selection groove 52 when the ball cover 20 rotates in the selection direction.

[0081] If the mode switching guide 50 is moved in the switching direction by actuating the mode switching solenoid coil 110, the mode switching guide 50 can move into the state in which the other end of the mode switching rod 40 is inserted into the connecting groove 53, and the other end of the mode switching rod 40 can be positioned in the first selection groove 51 or in the second selection groove 52 by moving the mode switching guide 50.

[0082] With reference to Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13 and Fig. 14 The first selection groove 51, in which the mode switching rod 40 is positioned, can have, in automatic switching mode, an initial position (zero position) A1 connected to the connecting groove 53 and an M-position (manual position) A2 spaced from the initial position A1 in one direction. If the ball cover 20 rotates in the selection direction, the mode switching rod 40 can move between the initial position A1 and the M-position A2 and be stopped in either the initial position A1 or the M-position A2.

[0083] This means that in automatic shifting mode, the starting position A1 and the M-position A2 can be fixed endpoints at which the shift rod 40 is fixed.

[0084] A detent projection 54 can protrude between the initial position A1 and the M-position A2. When the mode selector rod 40 climbs over the detent projection 54, an actuating force is generated. When the mode selector rod 40 is positioned in the initial position A1 or the M-position A2, the movement of the mode selector rod 40 can be inhibited by the detent projection 54, thus stopping the position of the mode selector rod 40.

[0085] With reference to Fig. 15, Fig. 16, Fig. 17, Fig. 18 and Fig. In manual switching mode, 19 can include the second selection groove 52, in which the mode switching rod 40 is positioned, a starting position (an N-stage, a neutral stage, a 3 / 4-stage selection position) B1, which is connected to the connecting groove 53, a 5 / 6-stage selection position B2, which is spaced from the starting position B1 in one direction, and a 1 / 2-stage selection position B3 and an R-stage selection position B4, which are spaced from the starting position B1 in the other direction.

[0086] When the ball cover 20 is rotated in the selection direction by actuating the shift rod 10, the mode selector rod 40 can move between the 5 / 6-stage selection position B2 and the R-stage selection position B4. When the driver releases the actuating force on the shift rod 10, the mode selector rod 40 can be returned to its initial position B1 by spring force.

[0087] This means that in manual shift mode, the 5 / 6-stage selection position B2, the 1 / 2-stage selection position B3 and the R-stage selection position B4 are not fixed endpoints at which the movement of the mode selector rod 40 is fixed in such a way that the mode selector rod 40 returns to the initial position B1 by spring force when the driver's actuating force is released after position B2, B3 or B4 has been selected.

[0088] The detent projection 54 is provided in the first selection groove 51. Therefore, in automatic switching mode, when the mode selector rod 40 is moved from the initial position A1 to the M position A2 by the selection manipulation of the switch rod 10, a high actuating force is generated when the mode selector rod 40 overcomes the detent projection 54.

[0089] In contrast, the second selection groove 52 does not have a projection similar to the detent projection 54 of the first selection groove 51. Therefore, in manual shift mode, when the shift rod 10 performs the selection manipulation, the mode selector rod 40 can move easily along the second selection groove 52 without interference.

[0090] Therefore, with the detent projection 54, the selection actuation force of the shift rod 10 in automatic shift mode can be higher than the selection actuation force of the shift rod 10 in manual shift mode and can thus be easily recognized by the driver.

[0091] The electronic switching device according to the present disclosure can comprise a guide tube 130 coupled to the other end of the drive shaft 30 and configured to be movable in the longitudinal direction of the drive shaft 30, a roller shaft 150 coupled to the guide tube 130 while penetrating one end of the guide tube 130 in the switching direction, and having two opposite ends to which a selector roller 140 is rotatably coupled, and selector detent holders 170 that are fixedly coupled to the other side of the ball cover holder 60 and have selector detent grooves 160, each having a surface with which the selector roller 140 is in contact. When the ball cover 20 rotates in the selection direction, the selector roller 140 can move along the selector detent grooves 160.

[0092] The guide tube 130 and the roller shaft 150 can be rigidly connected to each other. Alternatively, the roller shaft 150 can have a structure that is coupled in such a way that it is rotatable relative to the guide tube 130.

[0093] The first lateral grooves 61 can each be formed in the two opposing surfaces of the ball cover holder 60, which are oriented in the selection direction. The mode-switching guide bracket 90 and the selection detent holder 170 can each be rigidly connected to one side surface and the other side surface of the ball cover holder 60 in which the first lateral grooves 61 are formed.

[0094] One end of the guide tube 130 is inserted into the other end of the drive shaft 30 in such a way that the guide tube 130 is movably mounted and installed along the length of the drive shaft 30. The roller shaft 150 is integrally connected to the other end of the guide tube 130 and extends through the other end of the guide tube 130 in the direction of shifting. The selector roller 140 is rotatably connected to two opposite ends of the roller shaft 150.

[0095] The selection roller 140 can be installed so that it is in contact with the selection detent grooves 160 formed in the selection detent holders 170. If the ball cover 20 rotates in the selection direction, the selection roller 140 can move along the selection detent groove 160.

[0096] With reference to Fig. 25 The selection detent groove 160 can comprise a first groove 161, a second groove 162 arranged so that it is spaced apart in one direction from the first groove 161, and a third groove 163 and a fourth groove 164 arranged so that they are spaced apart in the other direction from the first groove 161.

[0097] The second groove 162, which is spaced apart in one direction from the first groove 161, and the third groove 163 and the fourth groove 164, which are spaced apart in the other direction from the first groove 161, can define paths of movement, each of which has a schematic arc shape.

[0098] This means that arc shapes can be formed, such that, starting from the center of the sphere cover 20, the radius to the first groove 161 is smallest, the radius to the second groove 162 and to the third groove 163 is longer than the radius of the first groove 161, and the radius to the fourth groove 164 is longer than the radius of the third groove 163.

[0099] With reference to the Fig. 11 and Fig. 25 can be in automatic switching mode, in which the mode switching rod 40 is positioned in the first selection groove 51, the selection roller 140 can be positioned in the first groove 161 when the mode switching rod 40 is positioned in the initial position A1, and the selection roller 140 can be positioned in the third groove 163 when the mode switching rod 40 is positioned in the M position A2.

[0100] Furthermore, with reference to Fig. 16 and Fig. 25, in manual switching mode, in which the mode switching rod 40 is positioned in the second selection groove 52, the selection roller 140 may be positioned in the first groove 161 when the mode switching rod 40 is positioned in the initial position B1, the selection roller 140 may be positioned in the third groove 163 when the mode switching rod 40 is positioned in the 1 / 2-stage selection position B3, the selection roller 140 may be positioned in the fourth groove 164 when the mode switching rod 40 is positioned in the R-stage selection position B4, and the selection roller 140 may be positioned in the second groove 162 when the mode switching rod 40 is positioned in the 5 / 6-stage selection position B2.

[0101] The electronic switching device according to the present disclosure can further comprise a second spring retaining pin 180, which is coupled in such a way that it penetrates the center of the cardan shaft 30 in the longitudinal direction, and a selector spring 190 with two opposite ends, which is connected to the second spring retaining pin 180 and the roller shaft 150 and is arranged to exert an elastic force on the roller shaft 150.

[0102] The second spring retaining pin 180 can be coupled such that it penetrates the center point of the drive shaft 30 longitudinally in the switching direction. The first spring retaining pin 70 and the second spring retaining pin 180 can be spaced longitudinally to the left and right of the center point of the drive shaft 30 and installed parallel to the center point of the drive shaft 30 in the longitudinal direction.

[0103] The selector spring 190 can be designed as a coil spring and provide a spring force that pulls the roller shaft 150 towards the inside of the drive shaft 30. Therefore, the selector roller 140 can always be kept in contact with the selector detent groove 160 by the spring force of the selector spring 190.

[0104] When the selector roller 140 moves into the second groove 162, the third groove 163 or the fourth groove 164, while the ball cover 20 rotates in the selection direction in the state in which the selector roller 140 is positioned in the first groove 161, the selector spring 190 can generate an actuating force while being stretched by a phase difference of the selector detent groove 160, and the guide tube 130 can move along the cardan shaft 30 to the extent that the selector spring 190 is stretched, such that the degree to which the guide tube 130 protrudes from the cardan shaft 30 can increase.

[0105] The electronic switching device according to the present disclosure can further comprise a pattern guide pin 200, which is fixedly connected to the ball cover 20, projects downwards and penetrates into the ball cover holder 60, and a pattern carrier 220, which is fixedly connected to a bottom of the ball cover holder 60 and has a pattern guide rail 210 which is configured to guide the movements of the pattern guide pin 200 in the selection direction and the switching direction.

[0106] The pattern guide pin 200 can be coupled to a central part of a lower part of the ball cover 20 and rotate together with the ball cover 20 when the ball cover 20 rotates in the selection and switching direction.

[0107] 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 as the ball cover 20 rotates in the selection and switching direction.

[0108] With reference to Fig. 27 and Fig. 28 The pattern guide rail 210 can include a selection rail 211 configured to guide the movement of the pattern guide pin 200 in the selection direction, and a switching rail 212 configured to guide the movement of the pattern guide pin 200 in the switching direction.

[0109] Fig. 27 and Fig. Figures 28 show states in which the pattern guide pin 200 is moved in the selection direction and the switching direction along the pattern guide rail 210 in automatic switching mode and in manual switching mode.

[0110] With reference to Fig. In the automatic switching mode, the mode switching rod 40 is positioned in the first selection groove 51. During selection manipulation (selection actuation), the mode switching rod 40 moves between the M position A2 and the initial position A1, which is the zero position. The mode switching rod 40 cannot perform the selection movement to the 5 / 6-stage selection position B2 and the R-stage selection position B4 based on the manual switching mode.

[0111] Therefore, in automatic switching mode, the movement of the pattern guide pin 200 in the selection direction is limited to the starting position A1 and the M-position A2.

[0112] In contrast, in manual shift mode according to Fig. 16 the mode switching rod 40 is positioned in the second selection groove 52, and during the selection manipulation the mode switching rod 40 can move along all selection paths from the initial position B1, which is the neutral stage (N stage), to the 5 / 6 stage selection position B2 in one direction and to the 1 / 2 stage selection position B3 and the R stage selection position B4 in the other direction.

[0113] Therefore, in manual switching mode, the pattern guide pin 200 can move freely along all selection paths in the selection direction.

[0114] The starting position A1 can correspond to the zero position in automatic switching mode, the starting position B1 can correspond to the N stage, the neutral stage or the 3 / 4 stage selection position in manual switching mode, and the starting position A1 in automatic switching mode and the starting position B1 in manual switching mode can be the same position.

[0115] Furthermore, the M position A2 in automatic shift mode can be the 1 / 2-stage selection position B3 in manual shift mode.

[0116] According to the present disclosure, the switching direction strokes can be limited differently in automatic switching mode and in manual switching mode. This can be achieved by the switching direction stroke limiting device described below.

[0117] The stroke in the shifting direction is relatively shorter in automatic shifting mode than in manual shifting mode, which can improve ease of use.

[0118] In contrast, the shift direction stroke in manual shift mode is relatively longer than in automatic shift mode, which can improve detection performance during the shifting process.

[0119] As described above, the shift direction stroke in automatic shift mode and the shift direction stroke in manual shift mode can be identical to the shift direction stroke during the shifting process of a vehicle with an automatic transmission and a vehicle with a manual transmission in the related prior art, which can eliminate the heterogeneity with the vehicle in the related prior art.

[0120] The electronic switching device according to the present disclosure can further comprise a permanent magnet 230, which is rigidly coupled to the ball cover 20, and a printed circuit board (PCB) 240, which is attached to the ball cover holder 60 such that it faces the permanent magnet 230 and which is configured to output a selected switching position by detecting a magnetic flux signal in accordance with a change in position of the permanent magnet 230 when the ball cover 20 rotates in the selection direction and the switching direction.

[0121] The mode-switching guide bracket 90 is connected to a side surface of the ball cover holder 60, the circuit board 240 is firmly connected to a side surface of the ball cover holder 60, which is spaced at a right angle from the mode-switching guide bracket 90, and the permanent magnet 230 is connected to the ball cover 20 such that it is opposite the circuit board 240.

[0122] The circuit board 240 has a Hall sensor which is configured to detect the permanent magnet 230 in such a way that the circuit board 240 can detect and output a selection position and a selected displacement position signal when the position of the permanent magnet 230 is changed in accordance with the rotations of the ball cover 20 in the selection and displacement directions.

[0123] The electronic switching device according to the present disclosure can further comprise a switching control 260 which is attached to the ball cover holder 60, which is configured to transmit a switching position signal output by the circuit board 240 to a vehicle control 250, and which is configured to control an operation of the mode switching solenoid coil 110 by receiving a signal from the mode selection part 120 which can select the automatic switching mode and the manual switching mode.

[0124] The switching control 260 can be positioned on one side of the circuit board 240, the circuit board 240 and the switching control 260 are electrically connected to receive signals, and the switching control 260 including the circuit board 240 can be covered and protected by a control cover 270.

[0125] The control cover 270 can be firmly connected to the side surface of the ball cover bracket 60.

[0126] With reference to Fig. 42 The automatic switching mode signal or the manual switching mode signal generated by actuating the mode selection part 120 is transmitted to the switching control 260, and the switching control 260 can control the operation of the mode switching solenoid coil 110 by using the automatic switching mode signal or the manual switching mode signal.

[0127] Furthermore, the switching position signal, which is selected by a selection rotation and a switching rotation of the ball cover 20, can be output via the circuit board 240 and then transmitted via the switching control 260 to the vehicle control 250, and operation of a vehicle drive part 280 can be controlled by the vehicle control 250.

[0128] The electronic switching device according to the present disclosure can comprise the mode selection part 120, which is configured to select the automatic switching mode or the manual switching mode; the mode switching rod 40, which is configured to be connected to the switching rod 10; the mode switching guide 50 with the first selection groove 51 and the second selection groove 52, which are configured to guide the movement of the mode switching rod 40 in the selection direction; and the connecting groove 53, which is configured to connect the first selection groove 51 and the second selection groove 52. When the automatic switching mode signal is generated or the manual switching mode signal is generated by actuating the mode selection part 120, the mode switching guide 50 is moved in the switching direction by the operation (actuation) of the mode switching solenoid coil 110.When the mode switching guide 50 moves in the switching direction, the mode switching guide 50 moves in the state in which the mode switching rod 40 is inserted into the connecting groove 53, so that the mode switching rod 40 can be positioned in the first selection groove 51 or in the second selection groove 52.

[0129] In automatic switching mode, the mode selector rod 40 can be positioned in the first selection groove 51 and moved along the first selection groove 51 to the starting position A1 or the M position A2 by actuating the selector rod 10 in the selection direction.

[0130] In automatic switching mode, the initial position A1 can be the zero position.

[0131] In addition, in manual switching mode, the mode switching rod 40 can be positioned in the second selection groove 52 and moved along the second selection groove 52 by actuating the switching rod 10 in the selection direction to any of the starting positions B1, the 5 / 6-stage selection position B2, the 1 / 2-stage selection position B3 and the R-stage selection position B4.

[0132] In manual switching mode, the starting position B1 can be the N stage, the neutral stage, and the 3 / 4 stage selection position.

[0133] Next, the stroke limiting device is described, which is able to limit the switching direction strokes of the shift rod differently according to the automatic switching mode and the manual switching mode.

[0134] The electronic switching device according to the present disclosure can comprise the mode selection part 120, which is configured to select the automatic shifting mode or the manual shifting mode, and the shift rod 10, which is actuated by the driver in the selection direction and the shifting direction. The shift direction strokes of the shift rod 10 can be restricted differently in the automatic shifting mode and in the manual shifting mode.

[0135] This means that the shift direction stroke in automatic shift mode can be limited to a relatively shorter length than in manual shift mode, which can improve ease of use.

[0136] On the contrary, the stroke in the shifting direction is relatively longer in manual shifting mode than in automatic shifting mode, which can improve detection performance during the shifting process.

[0137] As described above, the shift direction stroke in automatic shift mode and the shift direction stroke in manual shift mode can be identical to the shift direction stroke during the shifting process of a vehicle with an automatic transmission and a vehicle with a manual transmission in the related prior art, which can eliminate the heterogeneity with the vehicle in the related prior art.

[0138] To achieve this configuration, the electronic shift actuation device according to the present disclosure can comprise the ball cover 20, which is coupled to the shift rod 10 and configured to rotate in the selection and shift directions when the driver actuates the shift rod 10; a shift detent pin 290, which is coupled to the ball cover 20 and configured to rotate together with the ball cover 20 when the shift rod 10 is actuated in the shift direction; and a shift detent 320 with a shift cam 310 configured to be in contact with the shift detent pin 290. When the shift rod 10 is actuated in the shift direction, the shift detent pin 290 can move along the shift cam 310.

[0139] The switching detent pin 290 can be fixedly connected to a position on the ball cover 20 that is aligned in the switching direction.

[0140] More precisely, the permanent magnet 230 can be firmly coupled to one side of the ball cover 20 that points in the switching direction, and the switching detent pin 290 can be firmly coupled to the other side that points in the switching direction.

[0141] The permanent magnet 230 and the switching detent pin 290 can be coupled to the ball cover 20 in such a way that they point in opposite directions.

[0142] The detent pin 290 can have a projection 291, and the projection 291 of the detent pin 290 can be firmly connected to the ball cover 20.

[0143] The switching detent 320 can be positioned on one side of the switching detent pin 290 according to the switching direction. The switching cam 310 can be formed in a surface of the switching detent pin 320, and one end of the sliding detent 290 can have a structure that is always in contact with the switching cam 310.

[0144] When the ball cover 20 rotates in the shifting direction while the driver operates the shift rod 10, the shift detent pin 290 can move along the shift gate 310 when the shift detent pin 290 is in contact with the shift gate 310.

[0145] The stroke with which the shift detent pin 290 moves along the shift gate 310 can be relatively shorter in automatic shifting mode than in manual shifting mode and relatively longer in manual shifting mode than in automatic shifting mode.

[0146] According to the present disclosure, a second side groove 62 can be formed in a surface of the ball cover holder 60 based on the switching direction, and the projecting section 291 of the shift detent pin 290 can be inserted into and installed in the second side groove 62. When the shift rod 10 is actuated in the switching direction, the hub section 291 of the shift detent pin 290 comes into contact with one or the other end of the second side groove 62, and a full stroke in the switching direction can be restricted.

[0147] If the ball cover 20 is rotated in the shifting direction by actuating the shift rod 10, the ball cover 20, the shift detent pin 290 and the hub section 291 can rotate together in the shifting direction, and the second lateral groove 62 can extend upwards and downwards from the side surface of the ball cover holder 60 in the illustrated state to guide the rotation of the hub section 291 in the shifting direction.

[0148] Rotation in the switching direction can be inhibited if the projection 291 of the switching detent pin 290 comes into contact with an upper or lower end of the second side groove 62 when the ball cover 20 rotates in the switching direction.

[0149] The electronic switching actuation device according to the present disclosure can further comprise a switching detent carrier 330, which is rigidly coupled to one side of the ball cover holder 60 with respect to the switching direction, wherein the switching detent 320 is inserted into the switching detent carrier 330 and is installed so that it is movable in the switching direction, a switching spring 340 having two opposite ends which are connected to the switching detent carrier 330 and the switching detent 320 and which is configured to provide an elastic force for the movement of the switching detent 320, a switching solenoid coil 350 (also: a switching solenoid) which is rigidly coupled to the switching detent carrier 330 and configured to operate by receiving the automatic switching mode signal or the manual switching mode signal, and a stroke limiter 360 which is coupled to and configured with the switching solenoid coil 350.to move away from or towards the switching detent 320 when the switching solenoid coil 350 is operating, wherein the stroke limiter 360 is configured to limit the strokes of movement of the switching detent 320 differently in the switching direction based on a moved position.

[0150] The shift detent carrier 330 can be rigidly connected to a side surface of the ball cover holder 60, in which the second side groove 62 is formed. The shift detent 320 can be inserted and installed in the shift detent carrier 330 and is designed to be movable in the shifting direction.

[0151] When the ball cover 20 rotates in the shifting direction while the driver operates the shift rod 10, the shift detent pin 290 can move along the shift gate 310 if the shift detent pin 290 is in contact with the shift gate 310. The shift detent 320, when inserted into the shift detent carrier 330, can move in the shifting direction due to a phase difference of the shift gate 310 when the shift detent pin 290 moves.

[0152] The switching spring 340 can be designed as a coil spring. The two opposite ends of the switching spring 340 can be installed so that they are supported by the switching detent 320 and the switching detent carrier 330, and the switching spring 340 can provide a spring force that moves the switching detent 320 towards the ball cover 20.

[0153] The switching solenoid coil 350 can be permanently connected to the switching detent carrier 330, and the stroke limiter 360 can be coupled to the switching solenoid coil 350 in such a way that the stroke limiter 360 can move upwards or downwards when the switching solenoid coil 350 is actuated.

[0154] A solenoid cover 370 can be connected to the switching detent carrier 330, and the switching solenoid 350 and the stroke limiter 360 can be covered and protected by the solenoid cover 370.

[0155] When the driver operates the mode selector 120, the signal for automatic or manual shift mode can be generated. The automatic or manual shift mode signal can be transmitted to the shift control unit 260. The shift control unit 260 can control the actuation of the changeover solenoid 350 using the automatic or manual shift mode signal and a signal from the clutch pedal 380. The stroke limiter 360 can be moved up or down by actuating the changeover solenoid 350.

[0156] When the signal for automatic shift mode is generated, the stroke limiter 360 can be fixed in the position where it is moved to the upper side, where the shift detent 320 is located. When the manual shift mode signal and the clutch pedal actuation signal 380 are generated simultaneously, the stroke limiter 360 can be fixed in the position where it is moved to the lower side, away from the shift detent 320. If the manual shift mode signal is generated but the clutch pedal actuation signal 380 is not generated, the stroke limiter 360 can be fixed in the position where it is moved to the upper side.

[0157] The switching control 260 can control the operation of the switching magnet 110 using the automatic switching mode signal or the manual switching mode signal generated by actuating the mode selection part 120.

[0158] In addition, the shift control 260 can control the operation of the shift solenoid 350 by using the signal for the automatic shift mode or the signal for the manual shift mode and the actuation signal of the clutch pedal 380, which is generated by actuating the mode selection part 120.

[0159] If the automatic shift mode signal is generated by actuating the mode selector 120 in a vehicle (e.g., a two-pedal vehicle) that is not equipped with a clutch pedal, the shift control 260 can control the stroke limiter 360 such that the stroke limiter 360 is fixed in the position where it is moved to the upper side, where the shift detent 320 is located. If the manual shift mode signal is generated by actuating the mode selector 120, the shift control 260 can control the stroke limiter 360 such that it is fixed in the position where it is moved to the lower side, away from the shift detent 320.

[0160] A multitude of guide projections 321 and a multitude of guide grooves 331 for guiding the movement of the switching detent 320 in the switching direction can be formed in the switching detent 320 and the switching detent carrier 330 and coupled together.

[0161] The majority of the guide projections 321 can be formed on an outer circumferential surface of the detent 320 and spaced apart from one another. The guide grooves 331, of which there are the same number as the guide projections 321, can be formed in an inner circumferential surface of the detent carrier 330 and provided on sections that correspond to the guide projections 321.

[0162] The guide projection 321 and the guide groove 331 can extend in the switching direction in which the switching detent 320 moves.

[0163] With reference to Fig. 34 to Fig. 35 The switching gate 310 can include an inner groove 311, which is formed as a concave groove in a central section of a surface of the switching detent 320, an outer groove 312, which is formed as a concave groove outside the inner groove 311 and is connected to the inner groove 311 in a circumferential direction, and a projecting section 313, which is formed between the inner groove 311 and the outer groove 313 to connect the inner groove 311 and the outer groove 312, wherein the projecting section 313 has a cross-section that projects from the inner groove 311 and the outer groove 312 and is connected to the inner groove 311 and the outer groove 312 in the circumferential direction.

[0164] With reference to the Fig. 35, Fig. 36 to Fig. 37 A detent groove 322 is formed in a side edge section of a base surface of the switching detent 320, wherein one side of the upper end of the stroke limiter 360 is inserted into the detent groove 322 in the automatic switching mode situation. In the automatic switching mode situation, when the switching detent 320 is moved in the switching direction by actuating the switching rod 10 in the switching direction, the movement of the switching detent 320 in the switching direction can be restricted at a point in time when a side wall of the detent groove 322 comes into contact with a side surface of the stroke limiter 360.

[0165] If the automatic switching mode signal is generated by actuating the mode selection part 120, the switching control 260 can control the actuation of the switching solenoid coil 350 so that the stroke limiter 360 is in the state in which it is inserted into the detent groove 322.

[0166] Fig. Figure 35 illustrates a state in which the shift detent pin 290 is positioned in the inner groove 311 in automatic shift mode, and the Fig. 36 to Fig. Figure 37 illustrates states in which the shift rod 10 moves in the switching direction from the state in Fig. 35 is turned.

[0167] As in Fig. As shown in Figure 35, the position of the shift rod 10 can be fixed in the starting position (zero position) A1 or the M position (manual) A2 when the shift detent pin 290 is positioned in the inner groove 311 in automatic shift mode.

[0168] Fig. 36 and Fig. Figure 37 shows states in which the switching rod 10 rotates clockwise and counterclockwise in the switching direction relative to the state in Fig. 35 is turned.

[0169] When the ball cover 20 is rotated in the shifting direction by the rotation of the shift rod 10, the shift detent pin 290 moves from the inner groove 311 to the outer groove 312 in the state in which the shift detent pin 290 is in contact with the shift gate 310, and the shift detent 320 is moved to the left by the movement of the shift detent pin 290. In this case, the shift spring 340 is compressed.

[0170] The moment the side wall of the detent groove 322 comes into contact with a side surface of the stroke limiter 360 when the switching detent 320 moves to the left, the movement of the switching detent 320 in the switching direction is restricted. In this case, the switching detent pin 290 is positioned on a projecting section 313 of the switching gate 310.

[0171] When the shift detent pin 290 is positioned on the protruding part 313, the shift rod 10 can move into any shift position between a D stage, a (-) stage (downshifting), an R stage and a (+) stage (upshifting).

[0172] This means that when the shift rod 10 moves into any shift position between the D stage, the (-) stage, the R stage and the (+) stage, the shift detent pin 290 can move in the direction of the projecting section 313.

[0173] If the actuating force is released in the state in which the shift rod 10 is moved to any switching position between the D stage, the (-) stage, the R stage and the (+) stage, the shift detent pin 290 can be returned to the inner groove 311 by the spring force, and the shift rod 10 can be returned to the initial position A1 or the M position A2.

[0174] With reference to the Fig. 38, Fig. 39 to Fig. In manual switching mode, when the stroke limiter 360 is lowered by actuating the switching magnet 350, the stroke limiter 360 can be retracted and spaced away from the detent groove 322. In manual switching mode, when the switching detent 320 is moved in the switching direction by actuating the switching rod 10, the switching detent 320 can move without coming into contact with the stroke limiter 360.

[0175] This means that if the stroke limiter 360 is lowered and deviates from the movement path of the switching detent 320 according to the switching direction, the switching detent 320 does not come into contact with the stroke limiter 360 if the switching detent 320 moves in the switching direction. Therefore, the switching detent 320 can move over a maximum distance in the switching direction.

[0176] If both the manual shift mode signal and the clutch pedal actuation signal 380 are generated by actuating the mode selection part 120, the shift control 260 can control the operation of the switching solenoid coil 350 so that the stroke limiter 360 is retracted and spaced away from the detent groove 322.

[0177] Fig. Figure 38 illustrates a state in which the shift detent pin 290 is positioned in the inner groove 311 in manual shift mode, and the Fig. 39 to Fig. Figure 40 illustrates states in which the shift rod 10 moves in the switching direction from the state in Fig. 38 is being filmed.

[0178] As in Fig. As shown in Figure 38, the shift rod 10 can be positioned in the starting position (N-stage, neutral stage and 3 / 4-stage select position) B1, in the 5 / 6-stage select position B2, in the 1 / 2-stage select position B3 and in the R-stage select position B4 when the shift detent pin 290 is positioned in the inner groove 311 in manual shift mode.

[0179] If the actuating force of the shift rod 10 is released in the state in which the shift detent pin 290 is in one of the positions 5 / 6-stage selection position B2, 1 / 2-stage selection position B3 or R-stage selection position B4, the shift rod 10 can be returned to the starting position B1 by the spring force.

[0180] Fig. 39 and Fig. Figure 40 shows states in which the switching rod 10 rotates clockwise and counterclockwise in the switching direction relative to the state in Fig. 38 is being filmed.

[0181] When the ball cover 20 is rotated in the shifting direction by the rotation of the shift rod 10, the shift detent pin 290 moves from the inner groove 311 to the outer groove 312 in the state in which the shift detent pin 290 is in contact with the shift gate 310, and the shift detent 320 is moved to the left by the movement of the shift detent pin 290. In this case, the shift spring 340 is compressed.

[0182] When the detent 320 moves to the left, the detent pin 290 is guided over the projection 313, and the detent pin 290 is inserted into the outer groove 312 and then fixed in the outer groove 312.

[0183] When the shift detent pin 290 is positioned in the outer groove 312, the shift rod 10 can be positioned so that it is fixed in any shift position between a first stage, a second stage, a third stage, a fourth stage, a fifth stage, a sixth stage and an R stage.

[0184] Fig. Figure 41 illustrates a situation in which a manual shift mode signal is generated by actuating the mode selection part 120, but the clutch pedal 380 operating signal is not generated because the driver does not actuate the clutch pedal 380.

[0185] In this case, the switching control 260 controls the actuation of the switching solenoid coil 350 so that the stroke limiter 360 is inserted into the detent groove 322.

[0186] If the switching detent 320 is moved in the switching direction by actuating the switching rod 10, the side wall of the detent groove 322 comes into contact with a side surface of the stroke limiter 360 in such a way that the movement of the switching detent 320 in the switching direction is restricted and the manual switching process is not carried out any further.

[0187] This means that when the driver operates the shift rod 10 in the shifting direction in the state where the manual shift mode signal is generated and the clutch pedal 380 actuation signal is not generated, the movement of the shift detent 320 in the shifting direction is permitted until the side wall of the detent groove 322 comes into contact with a side surface of the stroke limiter 360. When the side wall of the detent groove 322 comes into contact with a side surface of the stroke limiter 360, the movement of the shift detent 320 in the shifting direction is restricted by the stroke limiter 360.

[0188] As described above, in the state where the movement of the switching detent 320 in the switching direction is restricted by the stroke limiter 360, the switching detent pin 290 is positioned on the projecting section 313, and the movement of the switching detent pin 290 towards the outer groove 312, which outputs the switching position signal, is restricted. Therefore, the switching position signal is not output, which can prevent faulty operation.

[0189] If the actuating force of the shift rod 10 decreases in the state in which the shift detent pin 290 is positioned on the preceding section 313, the shift detent pin 290 is returned to the inner groove 311 by the spring force, and the shift rod 10 is returned to the initial position B1.

[0190] The switching device system according to the present disclosure is described below.

[0191] The electronic switching device according to the present disclosure can comprise the switching rod 10, which can be actuated in the selection direction along a selection rail 211 and in the switching direction along a plurality of switching rails 212 connected to the selection rail 211, and the mode selection element 120, which is capable of selecting the automatic switching mode or the manual switching mode. The mode can be switched to the automatic switching mode, in which automatic switching manipulation is activated, or to the manual switching mode, in which manual switching manipulation is activated, according to the input of the mode selection element 120. When the switching rod 10 is actuated in the selection direction along the selection rail 211, the movable path of the switching rod 10 can vary depending on whether it is in the automatic or manual switching mode.If the switching rod 10 is actuated in the switching direction along the switching rail 212, the switching direction stroke of the switching rod 10 can vary depending on the automatic switching mode and the manual switching mode.

[0192] Furthermore, the electronic switching device according to the present disclosure may also include the mode-switching solenoid coil 110, which is configured to operate to switch the mode to the automatic switching mode or the manual switching mode, and the switching control 260, which is configured to control the operation of the mode-switching solenoid coil 110 by receiving the signal from the mode selection part 120.

[0193] The switching control device 260 can control the actuation of the switching magnet shaft 110 in such a way that the movement of the switching rod 10 in the selection direction is limited to the off position at the edge of the selection rail 211 in automatic switching mode.

[0194] With reference to Fig. In automatic shift mode, when the shift rod 10 is actuated in the selection direction, the selection movement of the shift rod 10 can be limited to the selection position of stage 5 / 6 and the selection position of stage R in manual shift mode.

[0195] The switching control 260 can control the operation of the mode-changing solenoid coil 110 such that a selection actuation force when the switching rod 10 is actuated in the selection direction in automatic switching mode is higher than a selection actuation force when the switching rod 10 is actuated in the selection direction in manual switching mode.

[0196] This means that in automatic shift mode, when the shift rod 10 performs the selection manipulation from the initial position A1 to the M position A2, the actuation force is generated when the mode selector rod 40 overcomes the detent projection 54 ("climbs over the detent projection 54"), and the selection actuation force in automatic shift mode is higher due to the detent projection 54 than the selection actuation force in manual shift mode. Therefore, it is possible to improve the driver's recognition performance.

[0197] With reference to Fig. 12 and Fig. 14 in automatic switching mode, when the mode switching rod 40 is positioned in the M position A2 by the selection manipulation of the switching rod 10, the position of the mode switching rod 40 is fixed in the M position A2 by the detent projection 54, and the movement of the switching rod 10 can be stopped.

[0198] The electronic switching device according to the present disclosure can further comprise the switching solenoid coil 350, which is configured to be operated by controlling the switching control 260 and to limit the switching direction strokes of the switching rod 10 differently according to the automatic switching mode and the manual switching mode.

[0199] The switching control 260 can control the operation of the switching solenoid coil 350 so that the switching direction stroke of the switching rod 10 is relatively shorter in automatic switching mode than in manual switching mode.

[0200] With reference to Fig. 27 and Fig. 28 The switching direction stroke of the shift rod 10 can be restricted so that it is relatively shorter in automatic switching mode than in manual switching mode and that it is relatively longer in manual switching mode than in automatic switching mode.

[0201] According to the present disclosure, in automatic switching mode the end section of the switching rail 212 is defined as a non-fixed end section, the switching rod 10 positioned in the initial position A1 or the M-position A2 is manipulated in the switching direction, and then the actuating force is released in such a way that the switching rod 10 can be returned to the initial position A1 or the M-position A2 by the spring force.

[0202] In automatic switching mode, the initial position A1 can be the zero position.

[0203] Furthermore, in manual shift mode, the shift rod 10 performs the selection manipulation to the 5 / 6-stage selection position B2, the 1 / 2-stage selection position B3 or the R-stage selection position B4, and then the actuating force is released in such a way that the shift rod 10 can be returned to the starting position B1.

[0204] In manual switching mode, the starting position B1 can be the N stage, the neutral stage, and the 3 / 4 stage selection position.

[0205] In manual switching mode, the end of the switching rail 212 is defined as a fixed end, the switching rod 10 is actuated in the switching direction, and then the actuating force is released in such a way that the switching rod 10 can be fixed in any switching position between the first stage, the second stage, the third stage, the fourth stage, the fifth stage, the sixth stage and stage R.

[0206] According to the present disclosure, the shift control device 260 can receive the actuation signal from the clutch pedal 380. If the automatic shift mode signal is entered by actuating the mode selection part 120, the shift control device 260 can control the operation of the switching solenoid coil 350 such that the movement of the shift rod 10 in the shift direction to the target shift position (the D stage, the R stage, the (+) stage or the (-) stage) is permitted independently of the actuation signal from the clutch pedal 380.

[0207] Furthermore, the switching control 260 can control the actuation of the switching solenoid coil 350 in such a way that the movement of the shift rod 10 in the switching direction to the target switching position (the first stage, the second stage, the third stage, the fourth stage, the fifth stage, the sixth stage or the R stage) is only permitted in the state in which both the manual shift mode signal by actuation of the mode selection part 120 and the actuation signal of the clutch pedal 380 are input.

[0208] Furthermore, if the manual shift mode signal is entered into the shift control 260 by actuating the mode selection part 120 and the actuation signal of the clutch pedal 380 is not entered, then

[0209] The switching control 260 controls the operation of the switching magnet 350 in order to limit the movement of the switching rod 10 in the switching direction in such a way that the switching rod 10 cannot move into the target switching position (the first stage, the second stage, the third stage, the fourth stage, the fifth stage, the sixth stage or stage R).

[0210] When the automatic shift mode signal is generated by actuating the mode selector 120 in a vehicle (e.g., a two-pedal vehicle) that is not equipped with a clutch pedal, the shift control 260 can control the stroke limiter 360 so that it is fixed in the position where it is moved to the upper side, where the shift detent 320 is located. When the manual shift mode signal is generated by actuating the mode selector 120, the shift control 260 can control the stroke limiter 360 so that it is fixed in the position where it is moved to the lower side, away from the shift detent 320.

[0211] In manual switching mode, the switching control device 260 can control the operation of the mode-switching solenoid coil 110 such that the switching rod 10 moves in the selection direction to the multiple selection positions along the selection rail 211 by actuating the switching rod 10. In automatic switching mode, the switching control device 260 can control the operation of the mode-switching solenoid coil 110 such that the movement of the switching rod 10 is limited to one or more of the plurality of selection positions along the selection rail 211.

[0212] In automatic switching mode, the path over which the switching rod 10 can be moved along the selection rail 211 by actuating the switching magnet 110 may be limited to a relatively shorter path than the path over which the switching rod 10 can be moved along the selection rail 211 in manual switching mode.

[0213] In manual switching mode, the majority of selection positions can be: the initial position B1, to which the switching rod 10 is returned by spring force when the actuating force of the switching rod 10 is released in the selection direction; the 5 / 6-stage selection position B2, which is positioned in one direction along the selection rail 211 from the initial position B1, so that the fifth or sixth stage can be selected by actuating the switching rod 10 in the switching direction; the 1 / 2-stage selection position B3, which is positioned in the other direction along the selection rail 211 from the initial position B1, so that the first or second stage can be selected by actuating the switching rod 10 in the switching direction; and the R-stage selection position B4, which is positioned at the edge in the other direction along the selection rail 211 from the initial position B1.so that the R stage can be selected by actuating the shift rod 10 in the shifting direction. The starting position B1 can be the 3 / 4 stage selection position B1, in which the third or fourth stage can be selected by actuating the shift rod 10 in the shifting direction.

[0214] In automatic shifting mode, one of the two selection positions can be alternately selected by actuating the shift rod 10 in the shifting direction. The two selection positions can include the initial position A1, in which the R stage or the D stage can be selected by actuating the shift rod 10 in the shifting direction, and the M position A2, which is positioned in the opposite direction along the selection rail 211 from the initial position A1, so that the (+) stage (upshift) or the (-) stage (downshift) can be selected by actuating the shift rod 10 in the shifting direction.

[0215] In automatic switching mode, the starting position A1 is a position identical to the starting position B1 in manual switching mode, and the M position A2 in automatic switching mode can be a position identical to the 1 / 2-stage selection position B3 in manual switching mode.

[0216] In automatic switching mode, the selection position of the shift rod 10 is set such that the movement in the selection direction is stopped in the M-position A2 and the shift rod 10 does not return to the starting position A1, even if the actuating force is released in the M-position A2.

[0217] The electronic switching device according to the present disclosure can further comprise the circuit board 240, which is configured to detect and output a switching position selected by actuating the switching rod 10 in the selection direction and in the switching direction, and a switching control 240 can transmit the switching position signal output by the circuit board 240 to the vehicle control 250, and by receiving the signal from the vehicle control 250 a drive part 280 can be operated.

[0218] In addition, the shift control unit can receive 240 speed information from the vehicle via signals from an accelerator pedal 390 and a brake pedal 400.

[0219] As described above, the electronic shifting device according to the present disclosure can switch the shifting mode between automatic and manual shifting based on the driver's intention. Therefore, it is possible to eliminate the complexity of the shifting process, which can enhance driver satisfaction and improve marketability.

[0220] Furthermore, according to the present disclosure, the electronic switching device can limit the switching direction strokes of the switching rod 10 to different lengths in accordance with the automatic switching mode and the manual switching mode, thereby improving the ease of handling and the detection performance during the switching process.
