It is about.

In general, a vehicle using a manual transmission has an advantage in that the transmission cost and fuel cost of the transmission can be reduced as compared to a vehicle using an automatic transmission. However, when using a manual transmission, the driver has to shift gears at any time. There is a disadvantage in that the ease of comfort and fatigue increases.

In order to alleviate this disadvantage, recently, a semi-auto clutch system has been developed that can operate a clutch pedal with a simple button input without stepping on the clutch pedal, such as an automatic transmission.

It protects the power train from overload as well as reduces the rotational vibration of the engine with the flywheel.

In a typical manual transmission vehicle clutch device, when the driver presses the clutch pedal, the piston of the mast cylinder is actuated by the force to generate oil pressure, and the generated oil pressure is released by the pneumatic pump by opening the valve hole. Through the clutch booster. At this time, the air pressure generated from the pneumatic pump is introduced into the clutch booster through the pneumatic induction pipe, and the inflow air pressure moves the clutch booster piston to move the push rod of the release cylinder, and the shift lever moves the clutch by the push rod. The clutch disc of the engine is separated from the drive plate of the engine and the power transmitted to the flywheel is cut off.

As shown in FIG. 4, according to one embodiment of the present invention, the shift signal generation unit 14 may be provided in the form of a gear rod 40 used for gear shifting. In more detail, the shift signal generator 14 may be implemented as a push button switch 41 provided in the gear rod 40.

The setting method by the operation of the setting unit 18 as shown in FIG. 5 will be described in more detail later.

Hereinafter, a mode-specific operation method and a setting method of the semi-auto clutch system for a manual transmission vehicle according to the exemplary embodiment of the present invention configured as described above will be described in detail.

- 동작모드별 운용 방법 --Operation Method by Operation Mode-

As described above, in one embodiment of the present invention, the control unit 15 is the state of the clutch pedal, the state of the accelerator pedal, the brake state and the type of the shift signal when the shift signal is generated in the shift signal generator 14. By driving the motor 16 according to a preset mode according to the position, it is possible to determine the position of the clutch pedal suitable for the driving state of the vehicle by the current driver.

The mode operated by the controller 15 may be determined as shown in the following table.

Table 1

Mode ＼ status	Previous mode	Brake signal	Shift signal input	action
Silent mode	-	ON	1 time	Clutch pedal fully integrated with accelerator pedal
Semi-automatic mode	Auto mode	OFF	1 time	Clutch pedal lift if stepping on the accelerator pedal
Manual mode	Semi-automatic mode	OFF	1 time	Accelerator pedal, clutch pedal up regardless of brake
Ascent mode	Silent mode	ON	Episode 2	Clutch pedal lifts to half clutch position
Turn uphill mode	Ascent mode	ON	1 time	Return to auto mode

In the table, the brake signal indicates that the brake is in operation when it is ON, and indicates that the brake is not in operation when it is OFF. In addition, the pedal is raised / lowered means the spatial state of the pedal installed in the manual transmission vehicle.

First, the automatic mode is a mode set when a shift signal is input once while the brake is operating regardless of the previous mode. In this automatic mode, the clutch pedal is fully linked to the state of the accelerator pedal operated by the driver. That is, in the automatic mode, the clutch pedal moves up when the accelerator pedal descends, and the clutch pedal descends when the accelerator pedal rises. This action prevents the engine from starting up. For example, when the vehicle is braked in the automatic mode and the gear is repeatedly stepped up and reversed, the gear shift is possible without pressing the gear shift button separately.

Next, the semi-automatic mode is a mode set when the shift signal is input once without the brake being operated in the automatic mode. That is, when the shift signal is input in the automatic mode, the clutch pedal descends, and after the gear shift is made, the clutch pedal is raised by pressing the accelerator pedal. However, even if the accelerator pedal is raised again, the clutch pedal does not lower again. However, when the brake signal comes in when the brake pedal is pressed in the semi-automatic mode, the clutch pedal is lowered to prevent the engine from turning off.

Next, the manual mode is a mode that is set when the shift signal is input once without the brake being operated in the semi-automatic mode. In manual mode, after the gear shift is made, the clutch pedal raises, regardless of whether the accelerator pedal is pressed. In the manual mode, the clutch pedal does not lower even when the brake is applied after the gear shift is made. This manual mode is a mode that can be executed when the vehicle is traveling at a high speed, and the clutch pedal is not lowered so that the engine brake can be used even when the brake is applied. That is, in the manual mode, when the clutch pedal descends when the brake is depressed for high speed driving, the power is cut off and the braking distance can be prevented from being extended.

Next, the uphill mode is a mode set when the shift signal is input twice in succession while the brake signal is input in the automatic mode. In this ascent mode, the clutch pedal is forcibly raised to the position corresponding to the half clutch while the brake is being applied. Therefore, in the uphill mode, a safe and comfortable uphill climbing is possible by significantly reducing a phenomenon that the vehicle is pushed back when the vehicle is restarted after stopping at the uphill climb.

This uphill mode can be released when the brake signal is input and the shift signal is input once while the uphill mode is being executed. That is, when the shift signal is input once while the brake is being applied, the uphill mode may be released by turning down the clutch pedal which has been raised to the half-clutch state and turning off the power.

- 사전 설정 방법 --Preset method-

First, a method of setting the accelerator pedal position will be described.

In a state where the accelerator pedal is not pressed, adjustment of the dip switch 52 for setting the accelerator pedal switch may be performed in the setting unit 18 as shown in FIG. 5 for setting the accelerator pedal position. For example, a state in which only the first switch of the dip switch 52 is turned on may be a dip switch state for setting an accelerator pedal position. Subsequently, when the setting switch 51 is pressed, a position detected by the second position sensor without storing the accelerator pedal may be stored. Subsequently, when the accelerator pedal is pressed down to the end and the setting switch 51 is pressed again, the position detected by the second position sensor may be stored while the accelerator pedal is lowered to the end. Information on the position of the accelerator pedal may be made using a storage space provided in the controller 15 or may be made using an external storage space such as a separate flash memory.

On the other hand, when the setting of the dip switch 52 is made or the setting switch 51 is pressed, an audible alarm such as a buzzer may be made to notify that the setting is made.

Next, the clutch pedal position setting method will be described.

As shown in FIG. 6, in one embodiment of the present invention, the position of the clutch pedal 60 can be considered to mean four positions in total. In FIG. 6, the position indicated by A is a position at which gear shifting can be performed smoothly. The position marked C is the initial position of the power transmission at which the vehicle starts to move and is in a half clutch state. The position indicated by B is a position where the movement of the clutch pedal is temporarily stopped before the clutch pedal moves from the position indicated by A to the position indicated by C. FIG. If the clutch pedal moves suddenly from the position of A to the position of C, the position of B is required because an impact may occur and cause discomfort to the driver. The position of D is the position where the clutch pedal is fully raised. In an embodiment of the present invention, the positions of A, B, and C shown in FIG. 6 may be set and stored.

First, a setting method for determining the position of A in FIG. 6 will be described.

The setting unit 18 as shown in FIG. 5 adjusts the dip switch 52 to find the A position of the clutch pedal. For example, only switch 2 of the dip switch 52 may be set to the on state. After the setting of the dip switch is made, while slightly pushing the shift gear toward the first stage, the clutch pedal is lowered toward the vehicle floor while pressing the shift signal generator (ie, the push button switch 41 of FIG. 4) a plurality of times. If the shifting gear is completely shifted while the push button switch 41 is briefly pressed, the press of the push button switch 41 is stopped and the setting switch 51 is pressed. At this time, the first position sensor 11 is detected. The location is stored as a location corresponding to A of FIG. 6.

Next, the C position of FIG. 6 is set.

After the setting of the A position is completed, the dip switch 52 for adjusting the C position of FIG. 6 is adjusted. For example, switch 1 of the dip switch 52 may be set to an off state, and switches 2 and 3 may be set to an on state. Through this dip switch 52 setting, the operation of the shift signal generator (ie, the push button switch 41 in Fig. 4) is determined to raise the clutch pedal. Similarly to the A position setting, the push button switch 41 is briefly pressed a plurality of times to raise the clutch pedal little by little. While raising the clutch pedal, you can find the location where the power of the vehicle is transmitted. That is, since the transmission gear is in the first stage, when the clutch pedal is raised little by little, it can be confirmed that the vehicle is transmitting power to move forward. With the brake pedal fully depressed, the clutch pedal is raised little by little to find the point where the power is transmitted to the maximum by the half-clutch in the state that the starting is not turned off, and the setting switch 51 is pressed to press the first position sensor 11 at this time. The position detected at is stored as a position corresponding to C of FIG. 6.

Next, the B position of FIG. 6 is set.

After the setting of the C position is completed, the dip switch 52 is adjusted to find the B position of FIG. 6. For example, only switch 2 of the dip switch 52 may be set to the on state. Through this dip switch 52 setting, the operation of the shift signal generator (ie, the push button switch 41 in FIG. 4) is determined to lower the clutch pedal again. Similarly to the A position setting, the push button switch 41 is briefly pressed a plurality of times to lower the clutch pedal little by little. Since the transmission gear is in the first stage, when the clutch pedal is lowered little by little in the half-clutch state, the power to advance the vehicle gradually decreases. The clutch pedal is lowered to the point where the power starts to be transmitted to the vehicle, and the setting switch 51 is pressed to store the position detected by the first position sensor 11 as the position corresponding to B of FIG. 6. Similarly to the acceleration pedal setting described above, an audible alarm such as a buzzer may be generated when the dip switch 52 or the setting switch 51 is operated in each position setting step.

Further, in one embodiment of the present invention, the speed at which the clutch pedal rises can be adjusted. This can be done by using the plurality of volume switches 53 of the setting unit 18 as shown in FIG. The ascending speed of the clutch pedal can be adjusted slowly or quickly according to the direction in which the volume switch 53 is rotated. The speed control of the clutch pedal's rising speed by the volume switch 53 may be set differently according to the above-described operation mode. For example, the volume switch B1 may adjust the speed at which the clutch pedal goes up from the B position to the C position of FIG. 6. The volume switch B2 can adjust the speed at which the clutch pedal rises from the C position to the D position when the accelerator pedal is pressed in the automatic mode. The volume switch B3 can adjust the speed at which the clutch pedal moves from the C position to the D position when the accelerator pedal is pressed in the semi-automatic mode. The volume switch B4 may adjust the speed at which the clutch pedal rises from the C position to the D position when the gear is shifted in the manual mode and the accelerator pedal is not pressed. The volume switch B5 may adjust the speed at which the clutch pedal moves from the C position to the D position when the gear shift is performed in the manual mode and the accelerator pedal is pressed.

As described above, one embodiment of the present invention can eliminate the driver's need to repeatedly operate the clutch pedal using the leg even in a situation where the vehicle stops / runs repeatedly, thereby reducing the driver's driving fatigue. Enables comfortable shifting.

In addition, since one embodiment of the present invention operates by automatically setting an appropriate operation mode according to the position of the clutch pedal, the position of the accelerator pedal, the brake state, and the like, the driver's driving comfort and driving safety can be improved.

In addition, in one embodiment of the present invention, since the position of the clutch pedal is set by dividing the plurality of sections and the rising time of the clutch pedal for each section can be adjusted, the shift according to the shift can be alleviated and smooth shifting is possible. The shift characteristics can be freely adjusted according to driving habits and the like.
