6 (a), (b) and (c) are enlarged views of part A of FIG. 6 , and (a), (b), (c) of FIG. 7 are enlarged views of part B of FIG. 7 . is an enlarged view.

5 to 7 , the motor rotation shaft 23 of the vehicle brake control system according to an embodiment of the present invention may be rotated in a first direction (M) or a second direction (N).

Here, the first direction M is a direction in which the contact roller 43 is interlocked with the rotation unit 30 to press the brake pedal P (see FIG. 6 ), and the second direction N is The contact roller part 43 may be linked to the rotation part 30 in a direction to release the pressure of the brake pedal P (see FIG. 7 ).

The interlocking body 351 is, as the motor rotation shaft 23 rotates in the first direction M, the mounting neck 37 comes into contact with the first inner end 3522a and then continues to rotate. It may be rotated in the first direction M.

Specifically, the interlocking body 351 is not rotated unconditionally by the rotation of the motor rotation shaft 23 in the first direction M, but the mounting neck 37 is the first inner end ( 3522a), and only when the motor rotation shaft 23 further rotates in the first direction M, it may be rotated in the first direction M.

This is because the separation distance between the first inner end 3522a and the second inner end 3522b is formed to be greater than the width of the mounting neck 37, so that the mounting neck 37 is the first inner end 3522a. ) because the rotational force of the motor rotating shaft 23 can be transmitted to the interlocking body 351 only when in contact.

The interlocking body 351 is, as the motor rotation shaft 23 rotates in the second direction (N), the mounting neck 37 comes into contact with the second inner end 3522b and then continues to rotate. It may be rotated in the second direction (N).

Specifically, the interlocking body 351 is not rotated unconditionally by the rotation of the motor rotation shaft 23 in the second direction N, but the mounting neck 37 is the second inner end ( 3522b), and only when the motor rotation shaft 23 further rotates in the second direction (N), it can be rotated in the second direction (N).

This is because the separation distance between the first inner end (3522a) and the second inner end (3522b) is formed to be greater than the width of the mounting neck (37), the mounting neck (37) is the second inner end (3522b) ) because the rotational force of the motor rotating shaft 23 can be transmitted to the interlocking body 351 only when in contact.

Specifically, with reference to FIGS. 6 and 7 , rotation of the rotating part 30 and the linkage part 35 by the mounting neck 37 will be described.

First, referring to FIG. 6 , the position movement of the mounting neck 37 in the first direction M is described. FIG. 6 (a) shows the mounting neck 37 and the rotating part 30 , and a schematic diagram showing the initial position of the linkage part (35).

The contact roller part 43 in the initial position may be in a state in which the brake pedal P is not pressed.

In the initial position, the mounting neck 37 may be located in the first position, and the detection bar 354 may be located in the sensing space G. As shown in FIG.

Here, the first position may be a position in which the mounting neck 37 is located in the center of the second through-piece 3522 (refer to (a) of FIG. 6 ).

The mounting neck 37 may be moved from the first position to the second position so that the contact roller 43 presses the brake pedal P.

Here, the second position may be a position in which the mounting neck 37 is in contact with the first inner end 3522a while rotating in the first direction M (see FIG. 6(b) ).

Specifically, while the mounting neck 37 is rotated from the first position to the second position, the rotating part 30 is rotated in the first direction M in conjunction with the mounting neck 37 , but , the interlocking body 351 may not be rotated in the first direction (M).

For this reason, when the mounting neck 37 is located in the first position or the second position, the detection bar 354 is not moved and is located in the sensing space G of the sensing unit 50 . It can be (see Fig. 6 (a), (b)).

The mounting neck 37 may be further rotated in the first direction M from the second position to move to a fourth position (see FIG. 6(c) ).

The interlocking body 351 may be rotated in the first direction M in conjunction with the rotating part 30 when the mounting neck 37 is moved from the second position to the fourth position.

In other words, in the fourth position, the mounting neck 37 is further rotated in the first direction M while in contact with the first inner end 3522a so that the interlocking body 351 moves in the first direction ( M) may be a position to be rotated.

When the detection bar 354 is rotated in the first direction M by the interlocking body 351 and is completely separated from the sensing space G, the brake pedal P is the contact roller part 43 It may be in a state pressurized to the maximum by

Referring to FIG. 7 , the movement of the mounting neck 37 in the second direction N will be described. It is a schematic diagram showing the state in which it is located.

The mounting neck 37 may be moved from the fourth position to the third position (see FIGS. 7A and 7B ).

Here, the third position may be a position at which the mounting neck 37 is in contact with the second inner end 3522b while rotating in the second direction N from the fourth position (FIG. 7(b)). ) Reference).

Specifically, while the mounting neck 37 is rotated from the fourth position to the third position, the rotating part 30 is rotated in the second direction N in conjunction with the mounting neck 37 , but , the interlocking body 351 may not be rotated in the second direction (N).

The mounting neck 37 may be further rotated from the third position in the second direction N to move to a fifth position (see FIG. 7(c) ).

The interlocking body 351 may be rotated in the second direction (N) by interlocking with the rotating part 30 when the mounting neck 37 is moved from the third position to the fifth position.

In other words, in the fifth position, the mounting neck 37 is further rotated in the second direction N while in contact with the second inner end 3522b so that the interlocking body 351 moves in the second direction ( It may be a position to be rotated to N).

As the mounting neck 37 is rotated from the fourth position to the fifth position, the contact roller 43 may release the pressure of the brake pedal P.

In this case, the detection bar 354 separated from the sensing space G is moved into the sensing space G according to the rotation of the interlocking body 351 in the second direction N, and the maximum When it is rotated at an angle, it can be separated from the sensing space G (refer to (c) of FIG. 7).

The connection mounting hole 353 may be formed to correspond to a rotation radius of the connection part 36 .

This means that the connection part 36 and the interlocking body 351 are connected during the movement of the mounting neck 37 from the first position to the second position or the movement from the first position to the third position. This is to avoid mutual interference.

When the detection bar 354 is not detected by the detection unit 50 while the motor rotation shaft 23 rotates in the first direction M, the control unit 60 controls the motor rotation shaft 23 ) can be controlled to stop the motor unit 20 (refer to (c) of FIG. 6).

When the detection bar 354 is not detected by the detection unit 50 while the motor rotation shaft 23 rotates in the first direction M, this means that the contact roller 43 is the brake pedal. Since (P) is in the maximum pressurized state, the control unit 60 controls the motor rotation shaft 23 to stop without further rotating the motor rotation shaft 23 in the first direction M.

When the detection bar 354 is not detected by the detection unit 50 while the motor rotation shaft 23 rotates in the second direction N, the control unit 60 controls the motor rotation shaft 23 ) may control the motor unit 20 to stop (see (c) of FIG. 7).

In this case, since the contact roller part 43 completely releases the pressure of the brake pedal P, the control unit 60 stops the motor rotation shaft 23 without further rotating the motor rotation shaft 23 in the second direction (N). to control to do so.

The body portion 10 may include a stopper 17 .

The stopper 17 may limit the rotation range of the rotation part 30 in the second direction N while being disposed to face the rotation part 30 .

In the present invention, it is possible to limit the rotation range of the motor rotation shaft 23 in the second direction N by providing the control unit 60 and the stopper 17 .

Specifically, referring to FIG. 7 , the rotation part 30 may not be further rotated in the second direction N by the stopper 17 while it is rotated in the second direction N.

The controller 60 may implement a first mode, a second mode, and a third mode in order to adjust the position of the mounting neck 37 deviated from the first position to the first position.

The control unit 60 may implement a first mode for rotating the motor rotation shaft 23 in the second direction (N).

When the implementation of the first mode is completed by the controller 60, the detection bar 354 may be in a state separated from the sensing space G (refer to (c) of FIG. 7).

When the rotation of the motor rotation shaft 23 is stopped by the stopper 17 during the implementation of the first mode, the control unit 60 moves the motor rotation shaft 23 in the first direction (M). The second mode of rotating by a set first angle may be implemented.

Here, the first angle means that when the motor rotation shaft 23 is rotated in the first direction M, the detection bar 354 is rotated while being interlocked with the rotation unit 30 and the sensing space G ) may mean an angle that allows it to be located within.

When the motor rotation shaft 23 is rotated by the first angle in the first direction M, the detection bar 354 may be positioned in the sensing space G as in the case of FIG. 6(b). have

After implementing the second mode, the controller 60 may implement the third mode of rotating the motor rotation shaft 23 in the second direction N by a predetermined second angle.

Here, the second angle means an angle at which the mounting neck 37 can be positioned from the second position to the first position.

When the third mode is implemented by the control unit 60 , the mounting neck 37 may be moved from the second position to the first position.

In this case, since the interlocking body 351 is interlocked with the rotating part 30 and does not rotate, the detection bar 354 can maintain a state positioned in the sensing space (G).

When implemented up to the third mode, the rotating part 30 , the linkage part 35 and the mounting neck 37 may be positioned at the initial positions shown in FIG. 6A .

8 is a schematic diagram for explaining an intermediate part of a vehicle brake control system according to an embodiment of the present invention.

The intermediate body 71 is attached to the brake pedal P, and may include an intermediate inclined portion 711 .

The intermediate inclination part 711 may form a space in which the front end of the user's foot F that steps on the brake pedal P is located.

If the intermediate inclination part 711 is not provided, when the user places the foot F on the brake pedal P, the front end of the foot F comes into contact with the intermediate body 71 and the brake pedal P It may make it uncomfortable to step on.
