The electronic transmission apparatus 1 according to the exemplary embodiment of the present invention may include a shift lever 100, a sensor unit 200, an indicator 300, and a base bracket 400.

The shift lever 100 may serve to select a shift stage by moving. More precisely, the shift lever 100 may rotate in a predetermined range in the front and rear or left and right directions to select a shift stage. The direction in which the shift lever 100 rotates is a rotational direction (this is called a shift direction) and a manual mode about the shift axis to select R (reverse), N (neutral), and D (forward). In order to select (M), it can be divided into a direction of rotation about a select axis (this is called a select direction).

That is, the sensing sensor 210 may detect the magnetic flux density according to the movement of the magnet 160 in the X-axis, the Y-axis, and the Z-axis, respectively, and convert the magnetic flux density into an electrical signal corresponding thereto. As the detection sensor 210, a 3D sensor may be used. The three-dimensional sensor is a sensor for detecting the operation of the object in the three-dimensional space and the direction of movement, according to an embodiment of the present invention measures the magnetic flux density according to the movement of the magnet 160 installed at one end of the shift lever 100 It can be measured. That is, in the case of the electronic shift apparatus according to the exemplary embodiment of the present invention, the movement and the select shaft 102 when the shift lever 100 rotates about the shift shaft 101 using one sensing sensor 210 are performed. You can detect all the movements when rotating around). Therefore, since it is not necessary to install separate Hall sensors around the shift shaft 101 and the select shaft 102 of the shift lever 100, the structure of the electronic transmission can be simplified to reduce the installation space and reduce costs. .

Preferably, the detection sensor 210 may detect the movement of the magnet 160 and output a first output signal and a second output signal according to the position of the magnet 160. Therefore, the position of the shift lever 100 may be determined by combining the first output signal and the second output signal of the detection sensor 210. The operation of the detection sensor 210 will be described later in detail with reference to FIGS. 9 to 11.

Assuming that the passage 301 has a shape, the shift stage displayed by the indicator 300 may display R (reverse), N (neutral), and D (forward) on the left vertical line, and manual shift on the middle vertical line. You can display the menus + (Up) and-(Down). In addition, the rightmost M (manual mode) display can be used to switch from the automatic shift mode to the manual mode.

In the indicator 300 having the passage 301 in the shape, a null 302 may be provided to be assigned to a neutral position. At this time, if the shift lever 100 is released after the shift stage is selected by the user, the shift lever 100 may be returned to the null position 302.

Meanwhile, a separate hall sensor (not shown) for detecting the position of the shift lever 100 may be installed in the passage 301 formed in the indicator 300. Therefore, by supplementing the function of detecting the position of the shift lever 100 through the detection sensor 210, it is possible to increase the position recognition rate for the shift lever 100, and may cause a malfunction in the detection sensor 210 or Error can be prevented.

Referring back to FIG. 2, the LED display unit 310 serves to display the shift stage selected by the user so that the user can recognize it. Since the shift lever 100 returns to the null position 302 after operation of the shift lever 100, there may be a problem in which the shift stage selected by the user may not be known. You can light up the selected gear.

The slide 320 may block foreign matter from entering the indicator 300 and the base bracket 400 and may allow the operation of the shift lever 100 to be smooth. The slide 320 may be disposed between the indicator 300 and the base bracket 400, and may include a hole through which the rod 120 of the shift lever 100 passes through the center of the slide 320. In addition, when the shift lever 100 is moved back and forth and left and right, the slide is also moved together to reduce frictional force due to the operation of the shift lever 100.

The base bracket 400 may include a groove 410 that forms a passage through which the detent 150 of the shift lever 100 passes. For example, the groove 410 is a passage 301 formed in the indicator 300

It is fabricated in a shape similar to the shape, and may form the deepest valley at the null position 302, and form a shallow valley away from the null position 302.

4 is an exploded perspective view illustrating a structure of a shift lever of an electronic transmission device according to an embodiment of the present invention, and FIG. 5 is a longitudinal cross-sectional view illustrating a structure of a shift lever of an electronic transmission device according to an embodiment of the present invention.

Preferably, the shift lever 100 of the electronic transmission 1 according to an embodiment of the present invention is a rod 120, knob 110, detent 150, shift guide 130, select guide ( 140 and the magnet 160.

The rod 120 forms a body of the shift lever 100 and may rotate about a shift shaft or a select shaft. As shown in FIG. 4, the rod 120 has a long rod shape as a whole, and a hinge portion 121 such as a through hole or a shaft is formed at a center thereof so that the rod 120 may rotate by a predetermined range in a left and right direction (select direction). Can be. In addition, a protrusion 122 connected to the slot 142 of the select guide 140 may be formed at the end of the rod 120.

Knob 110 (Knob) may be connected to one end of the rod 120 and may serve as a handle to allow the user to move the shift lever 100. Accordingly, the user moves the knob 110, and the rod 120 connected to the knob 110 may rotate about the shift shaft or the select shaft, thereby allowing the user to select a shift stage.

The shift guide 130 may serve to guide the rod 120 to rotate about the shift shaft. As illustrated in FIG. 4, shafts 131 may be formed at both sides of the shift guide 130 so that the rod 120 may rotate about the shift axis. 4 illustrates an example in which the shaft 131 is formed, but a hinge hole may be formed. In addition, the shift guide 130 has a groove 132 penetrating therein so that the rod 120 can be inserted into the shift guide 130, and a through hole or a shaft is formed at a central portion of the shift guide 130 so that the rod 120 can be hinged. Hinge portion 133 may be formed.

The select guide 140 may serve to guide the rod 120 to rotate about the select axis. As shown in FIG. 4, the select guide 140 is formed in a substantially 'c' shape to surround the shift guide 130, and a hinge portion 121 and a shift guide 130 of the rod 120 are formed at a central portion thereof. The hinge portion 141 may be formed to be hinged with the hinge portion 133 of the. A slot 142 connected to the protrusion 122 of the rod 120 may be formed at the end of the select guide 140. In addition, a coupling groove 143 for fastening the magnet 160 may be formed at an upper end of the select guide 140.

On the other hand, the shift guide 130 or the select guide 140, a separate Hall sensor for detecting the position of the shift or select direction of the shift lever 100 around the shift shaft 101 or the select shaft 102 (not shown) May not be installed). Therefore, by supplementing the function of detecting the position of the shift lever 100 through the detection sensor 210, it is possible to increase the position recognition rate for the shift lever 100, and may cause a malfunction in the detection sensor 210 or Error can be prevented.

The detent 150 may be connected to the lower portion of the shift lever 100, that is, the lower end of the rod 120 to be in contact with the groove 410 of the base bracket 400. This detent 150 allows the shift lever 100 to return to the null position 302. As shown in FIG. 5, the detent 150 is inserted into the groove 123 formed at the lower end of the rod 120 and is mounted in the downward direction in which the groove 410 is provided by the elastic member 152 such as a spring. Can be pushed out. Accordingly, the detent 150 guides the shift lever 100 to move along the passage formed in the groove 410, and when the user releases the shift lever 100, the detent 150 acts as a null member by the action of the elastic member 152. It may return to the deepest portion of the groove 410 corresponding to the location 302.

The magnet 160 is composed of an N pole and an S pole, and the sensor 210 of the sensor unit 200 detects a moving position of the rod 120 through a change in magnetic flux density according to the movement of the rod 120. To help. As shown in FIG. 4, the magnet 160 may be coupled to a shift lever 100, more specifically, a coupling groove 143 formed on a side of an upper end of the select guide 140. Therefore, when the rod 120 rotates about the shift axis, the magnet 160 moves back and forth, and when the rod 120 rotates around the select die, the magnet 160 can move up and down. Therefore, in the electronic transmission apparatus according to the exemplary embodiment of the present invention, the shift lever 100 rotates about the shift shaft 101 and the select shaft 102 through one magnet 160. Since all movements when rotating can be realized, the structure can be simplified. Preferably, the S pole of the magnet 160 may be connected to the select guide 140, and the N pole may be disposed to face the sensing sensor 210 of the sensor unit 200.

6 is a perspective view illustrating an operation of a shift lever of an electronic shift apparatus according to an embodiment of the present invention.

As illustrated in FIG. 6, a direction in which the shift lever 100 rotates may be divided into a direction rotating about the shift shaft 101 and a direction rotating around the select shaft 102.

형상의 통로(301)를 가진 인디케이터(300)에서 상하로 배열되어 있는 R, N, 또는 D 변속단을 선택하거나 Up(+) 또는 Down(-)을 선택하기 위해 변속 레버(100)를 전후로 이동할 때에 작용하는 회전축을 의미한다. 또한, 셀렉트 축은 M, N 등의 변속단을 선택하기 위해 변속 레버(100)를 좌우로 이동할 때에 작용하는 회전축을 말한다. 따라서, 변속 레버(100)를 전후 방향(103)으로 이동시킨다는 의미는 변속 레버(100)를 쉬프트 축(101)을 중심으로 회전시킨다는 의미일 수 있고, 변속 레버(100)를 좌우 방향(104)으로 이동시킨다는 의미는 변속 레버(100)를 셀렉트 축(102)을 중심으로 회전시킨다는 의미일 수 있다.The shift shaft 101 is, for example, shown in FIG. 3

To move the shift lever 100 back and forth to select the R, N, or D shift stages arranged up and down or to select Up (+) or Down (-) in the indicator 300 having the passage 301 having a shape. It means the rotation axis acting at the time. In addition, the select shaft refers to a rotating shaft that acts when the shift lever 100 moves left and right to select shift stages such as M and N. FIG. Accordingly, the shifting of the shift lever 100 in the front-rear direction 103 may mean that the shift lever 100 is rotated about the shift shaft 101, and the shift lever 100 is rotated in the left-right direction 104. Moving to may mean that the shift lever 100 is rotated about the select shaft 102.

7 is a view illustrating a state in which a shift lever rotates about a shift shaft of an electronic transmission device according to an embodiment of the present invention.

As shown in FIG. 7, when the user rotates the shift lever 100 about the shift shaft, the magnet 160 coupled to the select guide 140 may move to the shift shaft 101, that is, the shift guide 130. The distance to the end of the magnet 160 about the shaft 131 may be moved along a circumference having a radius d. Therefore, it can be sensed that the shift lever 100 moves back and forth to select R, N, D or +,-shift stage. As will be described later, the moving radius d1 of the magnet 160 when the shift lever 100 moves to select the R, N, and D shift stages moves the shift lever 100 to select the +,-shift stage. Since it is different from the radius d2 of the magnet 160 at the time, two cases can be distinguished.

8 is a view illustrating a state in which a shift lever rotates about a select shaft of the electronic transmission apparatus according to an embodiment of the present invention.

As shown in FIG. 8, when the user rotates the shift lever 100 about the select shaft, the magnet 160 coupled to the select guide 140 may move up and down. Therefore, it can be sensed that the shift lever 100 moves left and right to select the M or N shift stage. In FIG. 8, the magnet 160 moves downward when M is selected from N, but the reverse is also possible.

9 is a diagram illustrating a movement of a magnet according to a shift of a shift lever in an electronic shift apparatus according to an embodiment of the present invention.

형상의 통로(301)를 구비하는 인디케이터(300)를 따라 변속 레버(100)를 이동시키는 경우, 센서부(200) 상에서의 마그넷(160)의 이동을 나타내면 도 9와 같이 표현될 수 있다.Same as in Figure 3

When the shift lever 100 is moved along the indicator 300 having the passage 301 having a shape, the movement of the magnet 160 on the sensor unit 200 may be represented as shown in FIG. 9.

As described above, when the user rotates the shift lever 100 about the shift shaft, the magnet 160 coupled to the select guide 140 may shift the shift shaft 101, that is, the shaft 131 of the shift guide 130. It can be moved along the circumference having a radius (d) the distance to the end of the magnet 160 with respect to). As shown in FIG. 8, when the magnet 160 moves downward when selecting from M to N, the movement of the magnet 160 when the shift lever 100 moves to select R, N, and D shift stages. The radius d1 becomes smaller than the radius d2 of the magnet 160 when the shift lever 100 moves to select + and-shift stages.

As shown in FIG. 9, the position of the magnet 160 also varies according to the position of the shift lever 100 that selects R, N, D, or M, +,-shift stages. The position of the shift lever 100 may be sensed by detecting a change in magnetic flux density according to the position of the magnet 160 and outputting a signal. Here, the position of the magnet 160 can be defined simply by dividing it into the X direction and the Y direction, for example, the X direction is rotated about the front and rear direction, that is, the shift axis 101 of the shift lever 100. The front and rear directions of the magnet 160 corresponding to the direction, and the Y direction refers to the vertical direction of the magnet 160 corresponding to the left and right direction of the shift lever 100, that is, the direction of rotation about the select shaft 102. Can mean.

As described above, the detection sensor 210 may output the first output signal and the second output signal according to the position of the magnet 160. For example, the first output signal may be in the X direction of the magnet 160. The second output signal may mean a signal according to the position of the magnet 160 in the Y direction. That is, the first output signal includes information according to the position when the shift lever 100 rotates about the shift shaft 101, and the second output signal includes the shift lever 100 moving the select shaft 102. It may include information according to a position when rotating about the center. Therefore, when the first output signal and the second output signal output from the detection sensor 210 are combined, the position of the magnet 160 in the X and Y directions may be known, and thus the position of the shift lever 100 may be known. You will know which gear you choose.

10 and 11 are views illustrating an example of an output signal of a sensing sensor according to a position of a shift lever in an electronic shift apparatus according to an embodiment of the present invention.

The output signal of the detection sensor 210 according to the position of the magnet 160 on the detection sensor 210 may be represented in the form of a voltage. Accordingly, the horizontal axis in FIGS. 10 and 11 may mean a position of the shift lever 100, and the vertical axis may mean an output voltage of the sensing sensor 210 according to the position of the magnet 160 in the X or Y direction. have.

As described above, since the first output signal may mean a signal according to the position of the magnet 160 in the X direction, and the second output signal may mean a signal according to the position of the magnet 160 in the Y direction, FIGS. In FIG. 11, it is assumed that the solid line 211 represents the first output signal, and the dotted line 212 represents the second output signal.

First, in FIG. 10, an output signal is shown when the shift lever 100 selects the R, N, and D shift stages. When the shift lever 100 is in the null position 302 which is the initial position, the voltage of the first output signal is Ve and the voltage of the second output signal is Vf. Comparing the output voltage when the shift lever 100 moves from the initial null position 302 to D, N, and R, respectively, the second output signal 212 indicating the movement in the Y direction does not change much, but X It can be seen that the first output signal 211 indicating the movement of the direction shows a large difference when moving to D, N, and R. This is because, as shown in FIG. 9, the movement to D, N, and R has almost no change in position in the Y direction, and much change in position in the X direction.

11 shows the output signal when the shift lever 100 selects M, +,-shift stages. When the shift lever 100 is in the null position 302 which is the initial position, the voltage of the first output signal is Ve and the voltage of the second output signal is Vf as described above. Comparing the output voltage when the shift lever 100 moves from the initial null position 302 to M, + and-, respectively, the second output signal 212 indicating the movement in the Y direction does not change much, but X It can be seen that the first output signal 211 indicating the movement of the direction shows a large difference when moving to M, +,-. However, in the case of the M shift stage, since the position is slightly higher than the + and-shift stage, the voltage of the second output signal of the M shift stage is relatively larger than the voltage of the second output signal of the + shift stage. . As such, when the first output signal 211 and the second output signal 212 are combined, the position of the shift lever 100 may be known.

As described above, the first output signal and the second output signal output through the detection sensor 210 are transmitted to a vehicle integrated control system (Vehicle Integrated Control System) such as an ECU (Engine Control Unit), the ECU, etc. The position of the shift lever 100 may be sensed by combining the voltage values of the output signal and the second output signal to determine a shift stage selected by the user. In addition, the ECU or the like may transmit the information of the shift stage to the indicator 300 to display the shift stage selected by the user through the LED display 310. In addition, the ECU and the like converts the voltage values of the first output signal and the second output signal into CAN communication or the like, and transmits a control signal to the actuator so that the transmission can perform a shift.

10 and 11 illustrate only one example of an output signal of the sensing sensor 210, but are not limited thereto and may be implemented in various ways.

In the related art, since a plurality of sensors have to be used to detect the position of the shift lever moving in the front and rear or left and right directions, the structure of the transmission is complicated and costly.

However, according to the electronic transmission device according to an embodiment of the present invention, by using a single sensor to sense both the position of the shift lever moving in the shift direction and the select direction, it is possible to simplify the structure to reduce the installation space . In addition, the cost can be reduced by simplifying the structure of the accelerator pedal actuating device.
