3 is a view illustrating a shift pattern of an electronic transmission apparatus of a vehicle according to a preferred embodiment of the present invention.

Referring to the drawings, the electronic transmission apparatus of the vehicle of the present invention includes movement paths 10, 20, and 30 including one or more straight paths 10, 20, and 30 on which a plurality of gear stages are disposed. The manipulator 100 moving along the paths 10, 20, 30 is provided. The manipulator 100 is a means that the driver can directly operate, and is provided to enable the operation for shifting. The manipulator 100 may be, for example, a known shift lever.

In addition, the electronic transmission device of the vehicle of the present invention receives the input of the sensor 200 and the sensor 200 for detecting a change in the position of the operating body moving along the movement path (10, 20, 30) the operation body ( And a controller 300 for outputting a shift signal for controlling the transmission according to the operation of 100.

Therefore, the shift signal output from the controller 300 by the manipulation to the operation unit 100 is input to the transmission 400 of the vehicle and is configured to shift.

As shown in FIG. 3, the movement paths 10, 20, 30 of the preferred embodiment of the present invention include three straight paths 10, 20, 30, and the three straight paths 10. , 20 and 30 ends are connected to each other, and each of the straight paths is formed to form a right angle with the connected straight paths.

It is configured to move along the straight path described above, drawing a trajectory close to the straight line. However, the present invention is not limited thereto, and the manipulator 100 may be formed by means such as a slider that moves along the straight path.

The plurality of straight paths 10, 20, and 30 have a fixed point (Null) or the manipulator 100 which can maintain its position as long as the manipulator 100 does not have an external force. One of the temporary points (N, D, R) configured to automatically return to the fixed point (Null), wherein the fixed point (Null) and / or temporary points (N, D, R) are each straight The straight paths disposed at both ends of the path to be adjacent to each other and having the fixed point and / or the temporary points N, D, and R may be the fixed and / or temporary points N. , D, R) to be connected to each other by the intersection. Therefore, the manipulation body 100 is configured to move along the movement path formed by the connection of the straight paths 10, 20, 30.

At this time, the controller 300 is located at the position between the fixed point (Null) or temporary points (N, D, R) disposed at both ends of the linear paths (10, 20, 30) When the 100 is positioned, it is made so that the manipulator 100 does not recognize it as a valid position for shifting, and thus is different from any one of the null or temporary points N, D, and R. Only when the manipulator 100 is moved toward one side, the controller 300 recognizes that the manipulator 100 has made a valid movement for shifting.

On the other hand, by providing a known elastic member and the like between the fixed point (Null) and the temporary points (N, D, R) in the movement path, when the external force applied to the operating body 100 is released the operating body ( 100 may be automatically returned to the fixed point (Null).

In a preferred embodiment of the present invention, there is one fixed point (Null) on the movement path that the manipulator 100 moves. Therefore, even if the operating body 100 is moved for shifting, when the external force is released, it is made to return to the one fixed point Null.

The first straight path 10 includes a fixed point at one end and a first temporary point N at the other end, and the first straight path to include the fixed point at one end. A second straight path 20 connected to the second end and having a second temporary point D at the other end thereof, and a first temporary point N provided at the other end of the first straight path 10 at one end thereof; It comprises a third straight path 30 is connected to the other end of the first linear path 10 to include a third temporary point (R) to the other end thereof.

Preferably, the first straight path 10 is disposed in a horizontal direction such that a fixed point Null is positioned at one end and a first temporary point N is located at the other end, and the second straight path 20 is A second temporary point (D) is disposed at an extended end extending vertically downward from the fixed point (Null), and the third straight path 30 extends vertically downward from the first temporary point (N). Thus, the third temporary point R is disposed at the extension end. In addition, the P button (P) is spaced apart from the fixed point is arranged to enable a separate operation.

However, the linear paths of the present invention are not limited to the above-described configuration, and in another embodiment of the present invention, the first straight path 10, the second straight path 20, and the third straight path 30 are not limited thereto. May be arranged at other predetermined angles, not at right angles to each other.

Here, the fixed point (Null) on the first straight path 10 is a basic end of the shift stage, and is fixed when no shift is made, and the first temporary point N on the first straight path 10 is shown. ) Is a temporary point for selecting the N stage of the shift stage, the second temporary point D on the second straight path 20 is a temporary point for selecting the D stage of the shift stage, and the third temporary point ( R) is a temporary point for selecting the R stage of the shift stage.

In the shift pattern as described above, the existence of the N stage is based on a law that there must be an N stage in a neutral state between the D stage as the forward stage and the R stage as the reverse stage, and the present invention satisfies such a shift pattern. Has

On the other hand, in a preferred embodiment of the present invention, when the operating body 100 is located at the fixed point (Null), further comprising a P button (P) for selecting the P stage by a separate operation, the controller Is configured to receive a signal according to the operation of the P button (P). However, in the present invention, the P button P is not limited thereto, and may have a different type of switch structure, and may be provided in other positions without being provided in the manipulation body 100. Self-explanatory

4 illustrates a shift lock included in a shift pattern of an electronic transmission apparatus of a vehicle according to a preferred embodiment of the present invention.

The electronic transmission device of the vehicle of the present invention is provided with shift locks S1 and S2 to prevent misoperation when the operation body 100 moves for shifting and to limit shifting according to a vehicle state. That is, the controller 300 selectively controls the shift locks S1 and S2 according to the position and operation state of the operating body 100 to limit the movement of the operating body 100 to an appropriate range. For example, the control function limits a shift operation that is not required and prevents a shift operation that generates a risk factor according to the vehicle condition.

As shown, in the preferred embodiment of the present invention the shift locks S1 and S2 are provided on the second straight path 20 and the third straight path 30, respectively. That is, the shift locks S1 and S2 of the present invention are provided with two of the first shift lock S1 and the second shift lock S2, and the first shift lock S1 is provided with the fixed point Null. It is disposed between the second temporary point (D), the second shift lock (S2) is made to be disposed between the first temporary point (N) and the third temporary point (R).

The controller 300 controls the shift by controlling the shift locks according to vehicle conditions such as a safety button, a vehicle speed, and a brake pedal signal provided in the vehicle.

Hereinafter, a shift step using the electronic shift device of the vehicle of the present invention will be described in detail with reference to FIGS.

Hereinafter, for convenience of explanation, the fixed point (Null), the first temporary point (N), the second temporary point (D) and the third temporary point (R) to the Null end, the N end, the D end and the R end Mark it.

5 shows a moving step of the operating body 100 at the time of the R gear shift.

When the controller 100 receives the signal recognized by the sensor that the moving object 100 is moved to the initial position, that is, the N point for shifting the R stage in a state located at the fixed point (Null), the manipulation After the sieve 100 returns to the initial position after the shift for shifting, the shifting signal is output.

As shown, the manipulator 100 is moved along the first straight path 10 and the third straight path 30 for shifting the R stage, and thus, moves through the N stage. At this time, since the first straight path 10 and the third straight path 30 are formed at right angles to each other, a driver operating the manipulator 100 for R-speed shifting operates the manipulator 100. After moving to the N stage, it is necessary to operate up to the R stage in the orthogonal direction, and this structure prevents the misshift due to the inability to accurately move the manipulator 100 to the R stage in a situation where the driver intends to change the R stage. It is a structure to prevent.

Therefore, the R stage shifting which is moved along the first straight path 10 and the third straight path 30 arranged at right angles to each other as described above is a state in which the driver does not see the shift stage, for example, while driving. It offers the advantage of enabling accurate shifting without misoperation even in the state.

On the other hand, as described above, the electronic transmission device of the vehicle of the present invention is configured to output a signal in a state in which the operating body 100 returns to the fixed point (Null) after the shift operation, and further, for the shift When the operating body 100 is moved to the R stage and the external force is released, the control unit 100 is automatically returned to the fixed stage, the null stage.

Therefore, the driver applying external force to the manipulator 100 for shifting moves the manipulator 100 to the N stage for shifting the R stage, and then moves to the R stage again by moving in the perpendicular direction again to release the external force. In this case, the operating body 100 is automatically returned to the N stage and then moved in the perpendicular direction again to the fixed stage Null stage. When the manipulator 100 finishes moving to the null stage, the controller recognizes that the driver has made the R gear shift operation based on the movement of the manipulator 100 received through the sensor, and thus the R stage. By outputting the shift signal, the R stage shift is substantially performed in the transmission.

6 shows a moving step of the operating body 100 at the time of N-speed shift.

As shown, the N-stage is positioned on the first movement path as the fixed point (Null), and thus, the manipulator 100 moves on the first straight path 10 to shift the N-stage. To move along.

Accordingly, the first temporary point N located on the first movement path, that is, the N-end, is adjacent to each other as described above, so that the N-manipulator 100 is positioned at the fixed point Null. N-stage shifting is performed by directly moving from Null to the N-stage along the first movement path.

In addition, as described above, the electronic transmission device of the vehicle of the present invention is configured to output a signal in a state in which the operating body 100 returns to the fixed point (Null) after the shift operation, the operation for shifting When the sieve 100 is moved to the N stage and the external force is released, the controller 100 automatically returns to the fixed stage, the null stage, and when the manipulation body 100 finishes moving to the null stage, the controller receives the input received through the sensor. The driver recognizes that the N-speed shift operation is performed based on the movement of the manipulator 100 and outputs the N-speed shift signal accordingly, thereby substantially performing the N-speed shift in the transmission.

7 shows a moving step of the operating body 100 at the time of the D gear shift.

As shown, the D stage is positioned on the second movement path as the fixed point (Null), and thus, the manipulator 100 is positioned on the second straight path 20 for the D stage shifting. Is made to move along.

Accordingly, the second temporary point D, ie, the D stage, located adjacent to each other as described above and positioned on the second movement path, moves the manipulator 100 positioned at the fixed point to the fixed point. It is made to shift the D stage by directly moving from the (Null) to the D stage along the second movement path.

In addition, as described above, the electronic transmission device of the vehicle of the present invention is configured to output a signal in a state in which the operating body 100 returns to the fixed point (Null) after the shift operation, the operation for shifting When the sieve 100 is moved to the D stage and the external force is released, the controller 100 automatically returns to the fixed stage, the null stage, and when the manipulation body 100 finishes moving to the null stage, the controller receives the input received through the sensor. The driver recognizes that the D stage shifting operation is performed based on the movement of the operating body 100, and outputs the D stage shifting signal accordingly, thereby substantially performing the D stage shifting in the transmission.

8 shows a moving step of the operating body 100 during the P-speed shift.

As described above, in the electronic transmission apparatus of the vehicle of the present invention, the shift of the P stage is made through the P button P in the form of a button. The shifting of the P stage is performed in a state in which the operating body 100 is positioned at the null stage, and is operated by manipulation of the P button P. FIG.

Therefore, when the P button P is operated, the controller recognizes that the driver has made the P-stage shift operation, and outputs the P-stage shift signal accordingly, thereby substantially performing the P-stage shift in the transmission.

9 is a table showing the operating conditions of the shift lock according to the preferred embodiment of the present invention.

As described above, the electronic transmission of the vehicle of the present invention has a shift lock S1 on the second straight path 20 and the third straight path 30 in order to prevent misoperation of the operating body 100. , S2). Therefore, when the shift locks S1 and S2 are operated, the movement of the manipulator 100 is restricted by the shift locks S1 and S2, so that the manipulator 100 cannot reach D stage. And control of the R stage is made impossible.

The shift locks S1 and S2 are operated in accordance with vehicle conditions such as safety button, vehicle speed and brake pedal signals of the vehicle, and the control of the shift lock is made by the controller.

As shown in FIG. 9, the shift lock is operated when the operating body 100 is positioned at the null end in a state where the respective stages of the P, R, N, and D stages are shifted.

First, when the current shift stage is the P stage, when the brake pedal signal is ON and the vehicle speed is 5 km / h or less, the shiftable stage can be shifted in both the R stage, the N stage, and the D stage, but the safety button is in the OFF state. In this case, the shift locks S1 and S2 are operated so that the shift of the R stage and the D stage is impossible.

Secondly, when the current shift stage is the R stage, the brake pedal signal is ON, the vehicle speed is 5 km / h or less, and when the safety button is in the OFF state, the shift stage in which the shift is possible is made possible to shift the P stage and the D stage. However, when the brake pedal signal is not ON or the vehicle speed is not 5 km / h or less, the shift locks S1 and S2 are operated so that the gear shift can be shifted to the N gear only.

Thirdly, when the current shift stage is N, the brake pedal signal is ON, the vehicle speed is 5km / h or less, and when the safety button is OFF, the shiftable gear stage can be shifted to the P stage, and the brake pedal signal is When it is ON, the vehicle speed is 5 km / h or less, and the safety button is in the ON state, the shift stage in which the shift is possible is made possible to shift the R stage. However, when the safety button is in an OFF state when the brake pedal signal is not ON or the vehicle speed is not 5 km / h or less, the second shift lock S2 of the shift locks S1 and S2 is operated. Therefore, the gear shift is made so that only the gear shift to the D gear is possible.

Fourth, when the current gear is D, the brake pedal signal is ON, the vehicle speed is 5km / h or less, and when the safety button is OFF, the shiftable gear stage is available for P-shift and the brake pedal signal is When it is ON, the vehicle speed is 5 km / h or less, and the safety button is in the ON state, the shift stage in which the shift is possible is made possible to shift the R stage. However, when the brake button signal is not ON or the vehicle speed is not 5 km / h or less, and the safety button is OFF, only the second shift lock S2 of the shift locks S1 and S2 is operated. Therefore, the gear shift is made so that the gear shift to the D gear is possible.

The electronic shifting device of the vehicle of the present invention made as described above uses only a simple shift pattern, that is, four shift stages (Null, N, D, and R), two shift locks (S1, S2), and a P button (P). It has a structure made to enable the shift stage, thereby providing an excellent space utilization. In addition, by reducing the number of shift locks with respect to the conventional shift pattern, it also provides the advantage of reducing the manufacturing cost.

As mentioned above, although the preferred embodiment of the electronic transmission apparatus of the vehicle of the present invention has been described in detail, this is merely presented a specific example to aid in understanding the present invention, and is not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
