BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a clutch used in a vehicle, and more particularly, to a clutch used in a vehicle, To a method for controlling a clutch disc based on the stored data during a semi-auto operation process.

The manual clutch device is a device that operates the master cylinder, the release cylinder, the release bearing, the release lever, and the pressure plate in sequence by the operation of the clutch pedal, A clutch disc disposed between a wheel and a pressure plate is intercepted and connected to a fly wheel to intercept the power transmitted from the engine to the transmission.

In the manual clutch device, when the gear shift is to be performed, the clutch pedal must be pressed each time by using the left foot. In the case where the traffic light frequently travels in the city or traffic congestion frequently occurs, A lot of fatigue occurred to the legs and backs of the driver who operated the pedal.

In order to solve the inconvenience of the manual clutch, an automatic transmission in which the shift is automatically performed without operating the clutch pedal of the driver according to the driving state of the vehicle has been developed and widely used. However, if the initial transmission is expensive, The fuel consumption is increased by about 20 to 30 percent, and the maintenance cost is increased.

In order to overcome the disadvantage of the manual transmission in which the driver presses the clutch pedal each time by using the foot during gear shifting, the invented apparatus is a semi-auto clutch. Briefly, A driving motor for driving the piston in the driving master cylinder and a driving motor for moving the piston in the driving master cylinder are disposed on the manual transmission stick to move forward and backward to control the driving motor forward and backward And a controller for controlling the driving motor according to the input signal of the button, the driving signal of the vehicle, and the driving master cylinder.

The driving master cylinder of the semiautomatic clutch is important in the process of mounting the cylinder on the vehicle so that when the driving master cylinder is moved back and forth by the driving motor, The piston in the driving master cylinder is advanced to the point where the clutch disc and the flywheel are completely disconnected from the connection point (the point where the clutch disc is connected to the flywheel and the piston in the driving master cylinder is positioned backward) (I.e.

Conventionally, as a method of setting the piston moving section, a limit switch is positioned at both ends of a moving section of a push rod connecting a driving motor and a piston in a driving master cylinder, and the driving motor is operated several times in forward and backward directions A method in which a limit switch is moved and fixed to a point at which the clutch disc is sensed and connected to the clutch disc, or a method of setting a moving section by combining a means for changing the length of the push rod and a means for moving the limit switch Were used.

The conventional semi-automatic clutch device has a disconnection method in which the vehicle speed and the engine speed increase, and when the connection condition is reached, the piston is moved to the connection point by moving the piston located at the cutoff point by the drive motor operation Or the pushrod movement data is compared with the pushrod movement distance data after detecting the engine revolution speed (RPM) or the like, the pushrod movement data is shifted by a predetermined amount And the clutch disk is connected by repeating the process of reversing and stopping the clutch disk.

Problems to be solved in the conventional semi-auto clutch device are as follows. Firstly, the drive master cylinder is operated several times before and after backward movement in order to set the movement period of the piston at the time of installation. And secondly, in the case of a connection condition, a travel time from the cutoff point to the connection start point, at which the clutch disk and the flywheel start to connect, is required for the reason of connecting the clutch disk backward from the cutoff point, The power transmission is delayed. In the case of starting after a stop or starting after stopping on a ramp uphill, the power transmission is delayed, resulting in a problem in that the vehicle progresses and the vehicle is pushed backward.

In order to solve the above-described problems, the present invention is characterized in that after a motor drive volume is placed in a controller input unit, the drive motor is moved forward, backward, And when the shut-off button is depressed based on the stored data during the semi-auto operation process, the piston is positioned at the clutch disc cutoff point. When the cutoff button is released, the piston is moved to the clutch disc immediately before the clutch disc connection start point The time required for connecting the clutch disc from the connection condition signal of the controller is reduced, thereby solving the problem that the vehicle is delayed from the start at the start of the vehicle and at the start of the slope.

According to an aspect of the present invention, there is provided a driving apparatus comprising: a motor driving volume for moving a driving motor forward and backward in a setting mode; A motor rotation detection sensor for detecting a rotation position of a drive motor for driving the piston to calculate a movement position of the clutch disk; A mode selection button for switching the clutch disk position setting mode and the operation mode; An A point storing button for storing the clutch disc breaking point data while moving the piston in the setting mode; A point B storing button for storing point data immediately before the clutch disk connection; A C point storing button for storing clutch disc connection starting point data; A D point storing button for storing clutch disk connection completion point data; An E point storing button for storing clutch pedal end point data at which the clutch disk connection is completed and the release fork is completely separated from the release bearing; A drive motor for moving the push rod and the piston back and forth by an input signal of a forward button and a reverse button; A, B, C, D, and E point indicators for displaying the input completed state from the inputs of the A, B, C, D, and E point storing buttons in the setting mode; A flash ROM (EEPROM) for storing the clutch disc position data and holding the data value even in the power-off state; A controller for controlling input and output by a drive program; .

According to another aspect of the present invention, there is provided a driving method for driving a motor in which a motor driving volume is rotated from a setting mode selection of a mode selection switch to forward / A drive motor drive method for stopping the drive motor when the drive motor is not present; A storage method for storing clutch disk position points in a flash memory by using the A, B, C, D, and E point storage buttons while moving the drive motor forward and backward to store clutch disk points; A clutch disc interrupting step for rapidly advancing the drive motor in accordance with the pushing of the forward button from the operation mode selection of the mode selection switch to shut off the clutch disc; And a clutch disc connecting step of gradually connecting the clutch disc from the input signal of the engine speed increase or reverse button.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic overall configuration diagram of a semi-auto clutch system to which the present invention is applied.

The master cylinder M4 and the drive master cylinder M8 are constituted by push rods M2 and M6 and pistons M3 and M7 and the drive master cylinder M8 is connected to the master cylinder M8 when the clutch pedal M1 is operated M4 to the release cylinder M9 and also acts as a master cylinder in accordance with the rotation of the drive motor 11 in the motor drive mode.

The release cylinder M9 converts the hydraulic energy of the master cylinder M4 or the drive master cylinder M8 into mechanical energy and supplies the hydraulic energy to the clutch disc M4, And the switching gear M5 is for turning the rotational force of the driving motor 11 into a linear reciprocating motion and pushing the push rod M6 in the driving master cylinder M8 to generate the hydraulic pressure .

2 is a block diagram of a configuration of a semi-auto clutch drive device according to the present invention. The motor drive volume 1 is a piston in the drive master cylinder M8 while operating and stopping the drive motor 11 in the set mode, M7 in the forward and backward directions.

The motor rotation detection sensor 2 is a means for sensing the rotational speed of the drive motor 11 and for reading the moving state of the clutch disk M12.

The mode selection button is a button for selecting a setting mode and an operation mode operation. In the setting mode, the clutch disconnection process and the clutch disc position data of the vehicle are read during the connection process and then stored in the flash ROM 18. In the operation mode, Mode, and activates the clutch disc M12 based on the recalled clutch disc position data.

The A, B, C, D, and E point storage buttons (4, 5, 6, 7, 8) store the clutch disc position data values during the set mode operation and display the A, B, 12, 13, 14, 15, 16). The forward and backward buttons 9 and 10 are for blocking and connecting the clutch disc M12 by moving the piston M7 back and forth during the operating mode.

The controller 17 performs a predetermined control procedure to store the clutch disk position points A, B, C, D, and E in the setting mode in the flash ROM 18 as a nonvolatile memory, The drive motor 11 is rotated in the forward and reverse directions with reference to the buttons 9 and 10 and the set value.

Next, the control operation of the semiautomatic clutch according to the present invention is applied to the vehicle, and the operation mode and the setting mode will be described as follows.

3 is a detailed sectional view of the driving master cylinder for explaining the operation of the present invention.

<Setting mode>

1. Install the semi-auto clutch device on the vehicle.

2. Start the engine.

3. Place the mode selection button in the setting mode.

4. When the motor drive volume 1 is rotated in one direction, the drive motor 11 advances the piston M7 by a rotation increment of the motor drive volume 1 so that the clutch disk M12 is gradually cut off from the flywheel, The piston M7 is moved backward by the amount of rotation reduction so that the clutch disk M12 is gradually connected.

If there is no increase or decrease in the motor drive volume 1, the drive motor 11 is stopped, so that the piston in the drive master cylinder M8 is also stopped, thereby disabling the movement of the clutch disk M12.

5. As a method of setting the clutch disc cut-off point (A), try to put the gear stick in the first position while advancing the piston (M7) using the motor drive volume (1). If the gear stick smoothly enters the first gear position, the clutch disc M12 is completely shut off. Therefore, the A point storing button 4 is pressed to input the motor rotation detecting sensor 2 data at this point to the flash ROM 18 Remember.

6. As a method of setting the clutch disk connection start point C, a point where the engine speed is lowered is shown by gradually moving the piston M7 backward using the motor drive volume 1, ) And a disk connection start point (C) at which the flywheel slips and begins to be connected. The C point storing button 6 is pressed to store the data of the motor rotation detecting sensor 2 at this point in the flash ROM 18.

7. In the method of setting the point B immediately before the clutch disk connection, when the motor drive volume 1 is reversely rotated from the above-mentioned step 6 to slightly advance the piston M7, a point at which the engine speed rises again appears, Is a point (B) immediately before the clutch disk connection, immediately before the clutch disk M12 comes into contact with the flywheel. The B point storing button 5 is pressed to store the data of the motor rotation detecting sensor 2 at this point in the flash ROM 18.

8. As a method of setting the clutch disk connection completion point D, when the accelerator pedal is depressed so that the engine is not turned off, the motor drive volume 1 is rotated to move the piston M7 backward, Is the half-clutch point, which is the point at which the flywheel and clutch disc slip and connect.

When the motor drive volume 1 is further slowly rotated from this point, the starting of the vehicle is smoothly started. This point is the clutch disk connection completion point D where the clutch disk M12 and the flywheel are completely connected. The D-point storing button 7 is pressed to store the data of the motor rotation detecting sensor 2 at this point in the flash ROM 18.

9. In order to set the clutch pedal end point E, the clutch pedal M1 is pressed smoothly by pressing the clutch pedal M1 occasionally while moving the piston M7 backward by using the motor drive volume 1 This point is the clutch pedal end point E, with the piston M7 opening the hydraulic line coming from the master cylinder M4. The E point storing button 8 is pressed to store the data of the motor rotation detecting sensor 2 at this point in the flash ROM 18.

10. Place the mode select button in the operating mode.

<Driving Method>

A. The clutch must be disconnected quickly when the gear is inserted while the forward button (9) on the manual transmission is pressed, so that the movement of the piston is maximized to the clutch disc cutoff point (A) Drive the drive motor to advance at a speed.

B. After completion of the above step A, releasing the forward push button 9 causes the piston M7 to move backward so that the piston M7 is located at the point B immediately before the clutch disc closing point A from the clutch disc closing point A. In this process, the driving motor 11 is driven at the maximum speed so that the operation is performed quickly.

If the connection process of this process is made late, the progress of the vehicle is slowed down, and the phenomenon that the vehicle is pushed backward when the vehicle ascends uphill occurs.

C. When the accelerator pedal is depressed after step B, the piston M7 is gradually moved backward in accordance with the drive connection data to move the clutch disc M12 to the connection completion point D so that the clutch connection is smoothly performed. The process from the clutch disk connection completion point D to the clutch pedal end point E maximizes the connection speed to shorten the contact time between the release lever and the release bearing to suppress the shortening of the part life time.

D. In order to quickly perform the operation even when the reverse button 10 is pressed to place the piston M7 at the clutch pedal end point E in order to forcibly connect the clutch disk M12 during the operation, ) At a high speed.

In the conventional semi-auto clutch drive method, since the setting of the piston position data for each section is not easily performed, the speed control of the section can not be applied, resulting in a problem that the vehicle progresses slowly. As described above, It is possible to easily find the clutch disc disassembly position data of the vehicle to which the auto clutch is attached, and by using this, it is possible to precisely control the position and speed of the clutch disc by each section, have.
